Answer:

Part 1) The sum of the two angles equals 70 degrees

Part 2) The complementary angle is 19 degrees and the supplementary angle is 109 degrees

Step-by-step explanation:

Part 1) we know that

The sum of the interior angles in any triangle must be equal to 180 degrees

so

In the triangle JKL

[tex]m\angle JKL+m\angle KLJ+m\angle LJK=180^o[/tex]

we have

[tex]m\angle JKL=110^o[/tex]

substitute

[tex]110^o+m\angle KLJ+m\angle LJK=180^o[/tex]

[tex]m\angle KLJ+m\angle LJK=180^o-110^o[/tex]

[tex]m\angle KLJ+m\angle LJK=70^o[/tex]

therefore

The sum of the two angles equals 70 degrees

Part 2) we know that

If two angles are complementary, then their sum is equal to 90 degrees

If two angles are supplementary, then their sum is equal to 180 degrees

step 1

Find the complementary

Let

c ----> the complementary angle

[tex]m\angle c+71^o=90^o[/tex]

[tex]m\angle c=90^o-71^o=19^o[/tex]

step 2

Find the supplementary

Let

s ----> the supplementary angle

step 1

Find the complementary

Let

c ----> the complementary angle

[tex]m\angle s+71^o=180^o[/tex]

[tex]m\angle s=180^o-71^o[/tex]

[tex]m\angle s=109^o[/tex]

therefore

The complementary angle is 19 degrees and the supplementary angle is 109 degrees

Answer:

Therefore we can say that 98 boxes will be needed to hold all the paperweights.

Step-by-step explanation:

i) there are 1657 souvenir paperweights that need to be packed in boxes.

ii) each box will hold 17 paperweights

iii) therefore the number of boxes that will be needed are

   = [tex]\dfrac{total\hspace{0.15cm} number\hspace{0.15cm} souvenir\hspace{0.15cm} paperweights}{number\hspace{0.15cm} of\hspace{0.15cm} paperweights\hspace{0.15cm} per\hspace{0.15cm} box}[/tex]  = [tex]\dfrac{1657}{17}[/tex] = 97.471

iv) Therefore we can say that 98 boxes will be needed to hold all the paperweights.

Question 1:

For this case we must solve the following system of equations by the method of elimination:

[tex]8x-6y=-20\\-16x+17y=30[/tex]

We multiply the first equation by 2:

[tex]16x-12y = -40[/tex]

We have the equivalent system:

[tex]16x-12y = -40\\-16x + 17y = 30[/tex]

We add the equations:

[tex]5y = -10[/tex]

We divide between 5 on both sides of the equation:

[tex]y = - \frac {10} {5}\\y = -2[/tex]

We find the value of the variable "x":

[tex]8x-6 (-2) = - 20\\8x + 12 = -20\\8x = -20-12\\8x = -32[/tex]

We divide by 8 on both sides of the equation:

[tex]x = - \frac {32} {8}\\x = -4[/tex]

Thus, the solution of the system is:

[tex](x, y): (- 4, -2)[/tex]

Answer:

[tex](x, y): (- 4, -2)[/tex]

Question 2:

For this case we must solve the following system of equations by the method of elimination:

[tex]-4y-11x = 36\\20 = -10x-10y[/tex]

We multiply the first equation by 10:

[tex]-40y-110x = 360[/tex]

We multiply the second equation by -4:

[tex]40y + 40x = -80[/tex]

We have the equivalent system:

[tex]-40y-110x = 360\\40y + 40x = -80[/tex]

We add the equations:[tex]-70x = 280[/tex]

We divide by -70 on both sides of the equation:

[tex]x = \frac {280} {- 70}\\x = -4[/tex]

We find the value of the variable "y":

[tex]-4y-11 (-4) = 36\\-4y + 44 = 36\\-4y = 36-44\\-4y = -8[/tex]

We divide between -4 on both sides of the equation:

[tex]y = - \frac {8} {- 4}\\y = 2[/tex]

Thus, the solution of the system is:

[tex](x, y): (- 4,2)[/tex]

Answer:

[tex](x, y): (- 4,2)[/tex]

Answer:

0.9

Step-by-step explanation:

i) 1 nickel is equal to 5 cents

ii) 36 nickels will equal to = 36 × 5 = 180 cents

iii) 1 dime is equal to 10 cents

iv) 20 dimes will equal to = 20 × 10 = 200 cents

v) the ratio of 36 nickels to 20 dimes will equal to

  =  36 nickels ÷ 20 dimes

 = 180 cents ÷ 200 cents

 = [tex]\frac{9}{10}[/tex]

 = 0.9

To express the comparison of 36 nickels to 20 dimes as a ratio in lowest terms, calculate the value of nickels and dimes in pennies, then simplify the ratio. By converting to pennies and reducing, the ratio of 36 nickels to 20 dimes is 9:10.

The question asks to write the comparison of 36 nickels to 20 dimes as a ratio reduced to lowest terms. To compare the value of nickels and dimes, we must know their value in pennies, the smallest unit of US currency. Since 1 nickel is worth 5 pennies and 1 dime is worth 10 pennies, we can express 36 nickels and 20 dimes in terms of pennies.

36 nickels = 36 x 5 pennies = 180 pennies

20 dimes = 20 x 10 pennies = 200 pennies

Now, we write the comparison as a ratio:

180 pennies : 200 pennies

Next, we reduce this ratio to lowest terms by dividing both numbers by their greatest common divisor, which is 20 in this case:

180 ÷ 20 : 200 ÷ 20

9 : 10

Therefore, the ratio of 36 nickels to 20 dimes reduced to lowest terms is 9:10.

Answer:

The answer is x = 1

Step-by-step explanation:

Let¿'s solve for x in the equation:

(x + 5)/4 = (2x + 1)/2

x + 5 = 2 * (2x + 1)

x + 5 = 4x + 2

-3x = 2 - 5

-3x = -3

x = 1

Proof of x = 1

1 + 5/4 = 2 + 1/2

6/4 = 3/2

3/2 = 3/2 (Dividing by 2 at the left side)

We proved that x = 1 is correct

Step-by-step explanation:

Given Will ran the diagonal distance across a square field measuring 40 yards each sides .

∴The distance covered by Will was =[tex]\sqrt{40^{2}+40^2 }[/tex] yards

                                                         = [tex]40\sqrt{2}[/tex] yards=56.56 yards

Again James ran diagonal distance across a rectangle field with a length of 25 yards and a width of 35 yards.

So,distance covered by James was =[tex]\sqrt{25^2+35^2}[/tex] yards

                                                             =[tex]5\sqrt{74}[/tex] yards = 43.01 yards

∴Will ran longer distance.

∴Will ran 13.55 yards more than James.

To calculate the longer distance Will ran compared to James, find the diagonal distances each ran. Will ran approximately 13.56 yards longer.

To determine how much longer Will ran compared to James, we need to calculate the diagonal distances for each run.

Will ran 56.57 - 43.01 ≈ 13.56 yards longer than James. Thus, Will ran around 13.56 yards longer than James, as determined by subtracting the diagonal of the rectangular field from that of the square field. This calculation offers a quantitative measure of the difference in running distances, providing insight into their comparative performances.

The given equation is not the conditional equation.

Step-by-step explanation:

A conditional equation is true only certain values of the numbers present in it.

    for example  x + 3 = 9  is true only, if x = 6

                         3x - 5 = 10 is true only, if x = 5

The given equation is an Identity equation in which both sides of the equation is equal.    

                     3(x - 4) + 5x = 4x + 4(x - 3)

                     3x - 12 + 5x = 4x + 4x - 12

Answer:

No, the books had more sales by 5/6 being bigger (Greater Than) than 3/4.

By converting both fractions to have a common denominator of 12, it becomes clear that there were more books than toys for sale, as 10/12 (books) is greater than 9/12 (toys).

To determine whether there were more toys or books for sale, we need to compare the fractions ⅓ (representing toys) and ⅗ (representing books). To compare these fractions, they must have a common denominator. The least common denominator for 4 and 6 is 12. Converting both fractions to have the denominator of 12, you would get:

When comparing 9/12 (toys) to 10/12 (books), it is clear that there were more books than toys for sale since 10/12 is greater than 9/12.

6) In rectangle, diagonals are equal.

KM = LN

6x + 16 = 49

6x = 49 - 16

6x = 33

x = 33/6

x = 5.5

7) 2x + 4 =  5x - 11

2x - 5x = -11 -4

-3x = -15

x = -15/-3

x = 5

In  rhombus,diagonals make two congruent triangles

So, ∠ACD = ∠ACB

8) In Rectangle, diagonals are equal and bisect each other

x + 10 = 3x - 18

x - 3x =  -18 -10

-2x = -28

x = -28/-2

x = 14

Answer: ≈ 8%

Step-by-step explanation:

Total number of students = total number of boys + total number of girls

Total number of students = 88 + 75

Total number of students =  163

10.2% of the boys have blue eyes , this means that 10.2% of 88 have blue eyes

[tex]\frac{10.2}{100}[/tex] x 88 = 8.976

Since we are dealing with humans , therefore , this means that 9 boys have blue eyes.

Also , 5.3% of the girls have blue eyes means that 5.3% of 75 have blue eyes. That is

[tex]\frac{5.3}{100}[/tex] x 75 = 3.975 , therefore : 4 girls have blue eyes.

In total , 13 students have blue eyes

Therefore , to calculate the % of students that have blue eyes , we have :

13/163 x 100 = 7.975460123

Therefore : ≈ 8% of the students have blue eyes

Answer:

D. 5/12

Step-by-step explanation:

I will have a picture attached to the answer. But I will explain it overall.

So let's start off with what information we have: Bella ate 1/4 of the bar and Owen at 1/3 of the same bar.

So how much overall was gone by the two? Well, in this part we will add the two fractions.

1/3 + 1/4 =?

Yet, here's the thing, these two fractions have different denominators. What we have to do is make them the same denominator. In order to do so we have to find the Least Common Multiple of the denominators.

So with that in mind...

Multiples of 3: 3,6,9,12,15,18,21,...

Multiples of 4: 4,8,12,16,20,24...

Do you see a number that 3 and 4 have? Welp, I do! It's 12! So here is what going to happen! We will set up the problem like this!

1/3 times ? equal x/12

+ 1/4 times ? equal x/12

Now you may be wondering what is the question mark for and what is "x"? Here's the thing, since we know the new fraction we have to figure out what times the original denominators equal the new denominator! So with 1/3, what or how do we make the 3 into 12? Well 3 times 4 equals 12! So that is ?. The ? will be 4/4. Because whatever you do to the bottom you do to the top.

1/3 times 4/4 equals 4/12

Now we do the same thing for the 1/4 fraction. Except the question mark will be 3/3 since 4 times 3 equals 12

1/4 times 3/3 equals 3/12

Okay, now we have 4/12 + 3/12= x/12. Let's add the fractions. 4+3=7 and the 12 of the denominator will stay the same. So 1/3+1/4 or 4/12+3/12 now equals 7/12.

The real question is what is LEFTOVER of the granola bar? So we have what was devoured of the bar, so now we can subtract the part that was gone with the whole bar. So...

1 whole bar equals 12/12

- the devoured part equals 7/12

left over or untouched = 5/12

So the answer to the question is D. 5/12

I hope this helps you, I'm sorry this took me a long time, I again do have a picture attached to the answer. If you need any help or have a question please don't be afraid to ask! Have a good day!

Answer: option D.

The total amount of the granola bar is = 1.

Given that they have eaten 1/4 and 1/3 of the bar.

So they have eaten a total of [tex]\frac{1}{4}+\frac{1}{3}=\frac{7}{12}[/tex] of the bar.

So the remaining amount is = [tex]1-\frac{7}{12}=\frac{12}{12}-\frac{7}{12}=\frac{5}{12}[/tex].

So option D is right.

Answer:

(1/5)(10/3) = 10/15 = 2/3 mile

The friend lives [tex]$\frac{2}{5}$[/tex] of a mile away.

To solve this problem, we need to calculate the total distance based on the speed at which the bike is ridden and the time it takes to reach the friend's house.

First, we determine the speed at which the bike is ridden, which is given as [tex]$\frac{1}{5}$[/tex] of a mile per minute.

Next, we calculate the time it takes to reach the friend's house, which is [tex]$3\frac{1}{3}$[/tex] minutes. To work with this mixed number easily, we convert it to an improper fraction. [tex]$3\frac{1}{3}$[/tex] minutes is the same as [tex]$\frac{10}{3}$[/tex] minutes because [tex]$3\frac{1}{3} = 3 + \frac{1}{3} = \frac{9}{3} + \frac{1}{3} = \frac{10}{3}$[/tex].

Now, we can find the total distance by multiplying the speed by the time:

[tex]\[ \text{Distance} = \text{Speed} \times \text{Time} \][/tex]

[tex]\[ \text{Distance} = \frac{1}{5} \text{ mile/minute} \times \frac{10}{3} \text{ minutes} \][/tex]

When we multiply these two fractions, we multiply the numerators together and the denominators together:

[tex]\[ \text{Distance} = \frac{1}{5} \times \frac{10}{3} \][/tex]

[tex]\[ \text{Distance} = \frac{1 \times 10}{5 \times 3} \][/tex]

[tex]\[ \text{Distance} = \frac{10}{15} \][/tex]

We can simplify this fraction by dividing both the numerator and the denominator by their greatest common divisor, which is 5:

[tex]\[ \text{Distance} = \frac{10 \div 5}{15 \div 5} \][/tex]

[tex]\[ \text{Distance} = \frac{2}{3} \][/tex]

Therefore, the friend lives [tex]$\frac{2}{5}$[/tex] of a mile away.

=2x+−12+16

Combine Like Terms:

=2x+−12+16

=(2x)+(−12+16)

=2x+4

Final answer:

The simplified expression of 2(x-6)+2(8) is 2x + 4 after distributing the 2 and combining like terms.

Explanation:

To simplify the expression 2(x-6)+2(8), you need to distribute the 2 into the parentheses and then combine like terms. Distributing the 2 into the first set of parentheses gives us 2x - 12.

For the second set, multiplying 2 by 8 gives us 16. So the expression becomes 2x - 12 + 16. Adding together the numerical terms (-12 + 16) gives us 2x + 4. Therefore, the simplified expression is 2x + 4.

Devin buys his clothes in Illinois, so he would pay the sales tax rate of Illinois, which is 6.25%. Therefore, the correct answer is D. 6.25%.

Certainly! Devin buys his clothes in Illinois, where the sales tax rate is 6.25%. This means that for every dollar he spends on clothes, he pays an additional 6.25 cents as tax.

To calculate how much tax Devin pays on a $100 purchase, you can use the formula:

[tex]\[ \text{Tax Amount} = \text{Purchase Amount} \times \text{Tax Rate} \][/tex]

Substitute the values:

[tex]\[ \text{Tax Amount} = \$100 \times 0.0625 \][/tex]

[tex]\[ \text{Tax Amount} = \$6.25 \][/tex]

So, if Devin buys clothes worth $100 in Illinois, he would pay $6.25 as sales tax, which corresponds to the 6.25% tax rate of Illinois.

The unit rate is $4.25 per day for lunch.

To find the unit rate of how much it costs to buy lunch for one day, we divide the total cost by the number of days. In this case, the total cost is $21.25 for 5 days of lunch.

Here's the calculation to find the unit rate:

Divide the total cost by the number of days: $21.25 / 5 = $4.25

Hence, the unit rate is $4.25 per day for lunch.

Step-by-step explanation:

420 gallons of 90% antifreeze must be mixed with 60 gallons of 10% antifreeze to get mixture that is 80% antifreeze

Solution:

Let "x" be the gallons of 90% antifreeze

The, final mixture would contain (x + 60) gallons

Then by given question, we can say,

"x" be the gallons of 90% antifreeze must be mixed with 60 gallons of 10% antifreeze to get 80 % of (x + 60) gallons

Thus we frame a equation as:

[tex]x \times 90 \% + 60 \times 10 \% = (x + 60) \times 80 \%[/tex]

Solve the above equation for "x"

[tex]x \times \frac{90}{100} + 60 \times \frac{10}{100} = (x + 60) \times \frac{80}{100}\\\\0.9x + 6 = (x+60) \times 0.8\\\\0.9x + 6 = 0.8x + 48\\\\\text{Combine the like terms }\\\\0.9x - 0.8x = 48 - 6\\\\0.1x = 42\\\\x = \frac{42}{0.1} = 420[/tex]

Thus, 420 gallons of 90% antifreeze is used
