How can I solve 764+135 faster using a different strategy?

Answer:

  ∠3 = 114°

Step-by-step explanation:

Angle 3 is a corresponding angle to angle 7, since they are both in the southwest corner of the intersection of the transversal and the parallel lines. Corresponding angles have the same measure, so ...

 ∠3 = ∠7 = 114°

Answer:the correct answer is b

Step-by-step explanation:

Answer: The one who ran at the greater Average Speed in 1 hour ran the greater Distance.

Step-by-step explanation:

Speed (S) is the ratio of the distance (D) covered to the time (t) taken.

That is, S = D/t

Suppose Andrew ran a distance D1 in 1 hour (3600 seconds) at a Speed, say S1, we have

S1 = D1/t

We can then say he ran a distance

D1 = t × S1

= 3600S1

Similarly, let's say Karleigh ran a distance

D2 = t × S2

= 3600S2

Let us compare these two, you will notice that the bigger number between S1 and S2 is going to determine the bigger number between D1 and D2.

Let's choose random numbers for S1 and S2 for clarity, say S1 = 5, S2 = 10

D1 = 3600 × 5

= 18000

D2 = 3600 × 10

= 36000

This makes D2 bigger than D1.

I hope this is clear.

Answer:

Karleigh ran a greater distance. The slope of the line described by the data in her table increased at a rate of 1/10 mile per minute compared to Andrew’s 1/12 mile per minute.

Step-by-step explanation:

Marco scored 876 more points than Jasmine.

To find how many more points Marco scored than Jasmine, we subtract Jasmine's score from Marco's score.

Marco scored 1,753 points while Jasmine scored 877 points.

Thus, Marco scored 1,753 - 877 = 876 more points than Jasmine.

Answer:

The slope of the two points is 2.

Answer:

Angle 1:  100

Angle 2:  80

Step-by-step explanation:

A linear pair of angles is formed when two lines intersect.  The measure of a straight angle is 180 degrees, so a linear pair of angles is equal to 180 degrees.

Angle 1: x

Angle 2: (x * 3/4) + 5

x + (x * 3/4) + 5 = 180

x + 3/4x + 5 = 180

1 3/4x + 5 - 5 = 180 - 5

1 3/4x = 175

1 3/4x / 1 3/4 = 175 / 1 3/4

x = 100

Check:

(x * 3/4) + 5

(100 * 3/4) + 5

75 + 5

80

100 + 80 = 180

To find the measure of both angles that form a linear pair, set up an equation and solve for x.

To find the measure of both angles, let's assume that one angle is x degrees. According to the given information, the other angle is 3/4 of x degrees plus 5. So the measure of the other angle is (3/4)x + 5 degrees. Since the two angles form a linear pair, their measures sum up to 180 degrees. Therefore, we can write the equation: x + (3/4)x + 5 = 180. Solving this equation, we can find the value of x and then calculate the measures of both angles.

The simplified expression is

[tex]\frac{4}{5}(\frac{1}{4}c-5)=\frac{c}{5}-4[/tex]

Step-by-step explanation:

Given expression is

[tex]\frac{4}{5}(\frac{1}{4}c-5)[/tex]

To simplify the given expression:

[tex]\frac{4}{5}(\frac{1}{4}c-5)[/tex]

[tex]\frac{4}{5}(\frac{1}{4}c-5)=(\frac{4}{5}\times \frac{1}{4}c)-(\frac{4}{5}\times 5)[/tex] ( here using the distributive property )

[tex]=(\frac{1}{5}c)-(4\times 1)[/tex] (simplify the factors )

[tex]=\frac{1}{5}c-4[/tex] or

[tex]=\frac{c}{5}-4[/tex]

Therefore the simplified expression is

[tex]\frac{4}{5}(\frac{1}{4}c-5)=\frac{c}{5}-4[/tex]

Answer:

$36

Step-by-step explanation:

The original value is $37.50 so that is 100%.

A decrease of 4% from original value means that you are finding 96% of the value, since 100% -4%= 96%

So the new value is 37.50/100 ×96= $36

This is because:

100% ----- $37.50

1% --------- $0.375

96% ------- $36

or taking 96% of original value would be

96/100 × $37.50= $36

Which would give you the same answer

a. The equation of the line is [tex]y = \frac{28}{15}x+\frac{41}{30}[/tex]

b. The equation of the line is [tex]y = \frac{-7}{5}x+\frac{1}{5}[/tex]

The general equation of the line in slope-intercept form is:

y = mx + c

where m is the slope and c is the y-intercept

1. To get the slope:

[tex]m = \frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]

where (x₁ , y₁) and (x₂ , y₂) are two points that belong to the line

2. To get the y-intercept:

We pick any point (x , y) that belong to the line and use this point to substitute in the general equation:

y = mx + c

m is calculated from part 1 and (x , y) is a known point on the line. So, we solve for c which is the only unknown.

Now, for the required lines:

Part a:

The two given points are (2, 5.1) and (-1, -0.5)

representing (x₁ , y₁) and (x₂ , y₂)

i. Getting the slope:

[tex]m = \frac{-0.5 - 5.1}{-1 -2}=\frac{28}{15}[/tex]

ii. Getting the y-intercept:

I will use the point (-1, -0.5)

y = mx + c

[tex]-0.5 = \frac{28}{15}(-1)+c\\\\-0.5=\frac{-28}{15}+c\\ \\ c = \frac{41}{30}[/tex]

iii. Based on the above calculations, the equation of the line is:

[tex]y = \frac{28}{15}x+\frac{41}{30}[/tex]

Part b:

The two given points are (-2, 3) and (3, -4)

representing (x₁ , y₁) and (x₂ , y₂)

i. Getting the slope:

[tex]m = \frac{-4-3}{3--2}=\frac{-7}{5}[/tex]

ii. Getting the y-intercept:

I will use the point (3, -4)

y = mx + c

[tex]-4 = \frac{-7}{5}(3) + c\\ \\-4 = \frac{-21}{5}+c\\ \\c=\frac{1}{5}[/tex]

iii. Based on the above calculations, the equation of the line is:

[tex]y = \frac{-7}{5}x+\frac{1}{5}[/tex]

Hope this helps :)

x-1=2 therefore x is 3 so 2x squared is 36

Answer:

1.22474487139

Step-by-step explanation:

x = 3

so if 2x^2 - 1 = 2

add 1 to both equations

2x^2 = 3

next, divide 2 from both sides

x^2 = 3/2

x^2 = 1.5

now find the square root of 1.5

Step-by-step explanation:

2x3/5+1/5

Going by BoDMAS

Multiplication comes before addition

2x3/5+1/5 = 6/5 + 1/5 = (6+1)/5

= 7/5 = 1 2/5

Final answer:

The expression 2x3/5+1/5 is solved by first multiplying 2 by 3/5 to get 6/5 or 1.2, and then adding this to 1/5 to get the final answer of 7/5 or 1.4.

Explanation:

To solve the expression 2x3/5+1/5, you first need to perform the multiplication before the addition, according to the order of operations (PEMDAS/BODMAS). So, you need to multiply 2 by 3/5:

2 x 3/5 = 6/5 or 1.2

Now add this result to 1/5:

6/5 + 1/5 = 7/5 or 1.4

Therefore, the answer is 7/5 or 1.4.

Given,

Radius of basketball hoop = 9 inches

As the basketball hoop is in circular shape.

Circumference of basketball hoop = 2πr

We will put given radius = 9

Circumference of basketball hoop = 2*π*9

Circumference of basketball hoop = 2 . 9 . π

Therefore,

Circumference of basketball hoop is 2*9*π.

The right answer is Option D.

The equation has only one solution that is x = -15

Step-by-step explanation:

We have to convert the given statement in  form of equation to find the number

Let x be the number

then

According to given statement,

[tex]2x-7 = 3x+8\\-7 = 3x-2x+8\\-7 = x+8\\x = -7-8\\x = -15[/tex]

The equation has only one solution that is x = -15

Final answer:

The equation 'twice a number minus seven equals eight greater than three times the number' simplifies to 2x - 7 = 3x + 8, which has one solution: x = -15.

Explanation:

The original question asks us to solve an algebraic equation where twice a number minus seven is equal to eight greater than three times that number.

To translate this into an algebraic expression, let the unknown number be x.

This gives us the equation 2x - 7 = 3x + 8.

To solve this equation, we can subtract 2x from both sides to get -7 = x + 8 and then subtract 8 from both sides to isolate x, resulting in x = -15.

To answer part B, this type of linear equation will only have one solution because it’s a linear equation with a non-zero coefficient in front of the variable x.

Dimensions are length 20 meter and width 14 meter

Solution:

Let "a" be the length of rectangle

Let "b" be the width of rectangle

Given that,

A rectangle has width that is 6 meters less than the length

Width = length - 6

b = a - 6

The area of the rectangle is 280 square meters

The area of the rectangle is given by formula:

[tex]Area = length \times width[/tex]

Substituting the values we get,

[tex]Area = a \times (a-6)\\\\280 = a^2-6a\\\\a^2-6a -280=0[/tex]

Solve the above equation by quadratic formula

[tex]\mathrm{For\:a\:quadratic\:equation\:of\:the\:form\:}ax^2+bx+c=0\mathrm{\:the\:solutions\:are\:}\\\\\quad x_{1,\:2}=\frac{-b\pm \sqrt{b^2-4ac}}{2a}[/tex]

[tex]\mathrm{For\:}\quad a=1,\:b=-6,\:c=-280:\quad a_{1,\:2}=\frac{-\left(-6\right)\pm \sqrt{\left(-6\right)^2-4\cdot \:1\left(-280\right)}}{2\cdot \:1}[/tex]

[tex]a =\frac{6 \pm \sqrt{36+1120}}{2}\\\\a = \frac{6 \pm \sqrt{1156}}{2}\\\\a = \frac{6 \pm 34}{2}\\\\Thus\ we\ have\ two\ solutions\\\\a = \frac{6+34}{2} \text{ or } a = \frac{6-34}{2}\\\\a = 20 \text{ or } a = -14[/tex]

Since, length cannot be negative, ignore a = -14

Thus solution of length is a = 20

Therefore,

width = length - 6

width = 20 - 6 = 14

Thus dimensions are length 20 meter and width 14 meter
