Step-by-step explanation:

8+7=15

For the numbers 8, 7, and 15, the true statements are '15 is 7 more than 8' and, when rephrased correctly, '7 is 8 more than 15'. The concept of significant figures plays an important role in mathematical operations to maintain the accuracy of results based on the precision of original numbers.

The fact family model is used to represent the relationship between three numbers that can form addition and subtraction statements. For the numbers 8, 7, and 15, only some of the given statements are true. Let's verify each statement:

15 is 7 more than 8: This statement is true, as 8 + 7 equals 15.

15 is 8 less than 7: This statement is false, as adding 8 to 7 gives us 15, not taking 8 from 7.

7 is 15 less than 8: This statement is false, as subtracting 15 from 8 would give us a negative number, not 7.

7 is 8 more than 15: This statement is true when we rephrase it correctly as 7 + 8 equals 15.

Therefore, only two statements are accurate: '15 is 7 more than 8' and '7 is 8 more than 15' when considered as 7 + 8 = 15.

The subject of significant figures and rounding is also related to mathematics. When performing mathematical operations, significant figures are crucial to ensure that our answers are as accurate as the precision of the numbers we started with, without overstating the certainty of our results. This becomes important when adding, subtracting, multiplying, or dividing numbers in mathematics.

Answer:

Step-by-step explanation:

see the attached figure to better understand the problem

Let

x -----> the number of weeks

y ---->skiing distance in kilometers

Looking at the graph of Jake's goal

we have the ordered pair (6,5)

That means

The number of kilometers from Jake's goal for week 6 is 5 kilometers

and

In the actual Jake is skiing at 4.5 km at week 6

so

[tex]4.5\ km < 5\ km[/tex]

therefore

He is below his goal

Answer:

The second option is best to choose.

Step-by-step explanation:

Joshua plans on working 3 days a week for 8 weeks. Therefore, Joshua will work for (8 × 3) = 24 days.

For the first option, Joshua earns $20 each day he works. So, in 24 days he will earn (20 × 24) = $480.

For the second option, he earns one nickel for agreeing to work, and that amount doubles each day he works after that.

So, the total earning of Joshua after 24 days of work will be

0.05 + 0.1 + 0.2 + 0.4 + 0.8 + 1.6 + ......... up to 24 terms {Since 1 nickel is equal to $0.05}

Now, this is an G.P. series sum and first term is 0.05, common ration is 2 and the number of terms is 24.

So, the sum = [tex]0.05 \times \frac{2^{24} - 1 }{2 - 1}[/tex]

= $838860.75

Therefore, the second option is best to choose. (Answer)

Final answer:

To decide between the payment options, Joshua should calculate the total income for the first option ($480) and compare it to the exponentially growing total of the second option, which would be far greater due to the daily amount doubling. Therefore, the second option is the more lucrative choice.

Explanation:

The student's question pertains to determining which of the two payment options offered by Joshua's uncle for work on a soybean farm is more advantageous. Joshua needs to calculate the total earnings for each option over the course of 8 weeks, given that he will work 3 days each week. For option one, it is straightforward: $20 per day times 3 days per week times 8 weeks equals a total of $480. Option two, however, requires calculating the total amount for a doubling sequence starting with a nickel ($0.05).

For option two, the earnings for each week will look like this:

Week 1: Day 1 = $0.05, Day 2 = $0.10, Day 3 = $0.20

Week 2: Day 1 = $0.40, Day 2 = $0.80, Day 3 = $1.60
...and so on. The amount doubles each day Joshua works.

Calculating this for the 24 days (3 days times 8 weeks) will show that on day 24, Joshua's daily earnings would be $0.05 ×223 (since the first day is $0.05 and does not double).

Comparing the total earnings from both options will reveal that Joshua will earn significantly more with the second option. Therefore, Joshua should choose the second payment option.

Answer:

{(-2,3), (7,-6) } -----> y - 15 = -[tex]x^{2}[/tex] + 4x

                               x + y = 1

{(-5, 8). (3,0) } ----> y + 12 = [tex]x^{2}[/tex] + x

                              x + y = 3

{(-2,5),(3,-5) } -----> y + 5 = [tex]x^{2}[/tex]  - 3x

                               2x + y = 1

{(2, 3), (8,9)} -----> y-17 = [tex]x^{2}[/tex] - 9x

                              -x + y = 1

Step-by-step explanation:

The simplest way to find the answer is by solving all the equations and finding the value of x and y for each of them.

Solving the equations ->

y + 12 = [tex]x^{2}[/tex]  + x

x + y = 3

Substitute y = 3-x from second equation to first and solving the quadratic equation obtained i.e solving [tex]x^{2}[/tex] + 2x -15 = 0 , we get values of x = -5 , 3 and the corresponding values of y by substituting values of x in second equation , y = 8, 0 respectively. So, solution matched  = {(-5, 8). (3,0) }.

Similarly solving other equations using exactly the same method as above we get the following solutions,

For,

y - 15 = [tex]x^{2}[/tex] + 4x

x - y = 1

we don't get any integer solution for this hence it has no match.

For,

y + 5 = [tex]x^{2}[/tex] - 3x

2x + y = 1

we get x = 3,-2 and corresponding y = -5,5

So, solution is {(-2,5),(3,-5) }

For,

y- 6 = [tex]x^{2}[/tex] – 3x

x + 2y = 2

we again don't get any integer solution for x and y so this has no match.

For,

y-17 = [tex]x^{2}[/tex] - 9x

-x + y = 1

we get x = 2,8 and corresponding y = 3,9

So, {(2, 3), (8,9)} is the solution match.

Lastly for,

y - 15 = -[tex]x^{2}[/tex] + 4x

x + y = 1

we get x = -2,7 and corresponding y = 3,6

So, {(-2,3), (7,-6)} is the solution match.

Answer:

The given expression represents the Associative Property of Addition.

Step-by-step explanation:

Here, the given expression is given as:

(2+3.4) + 6 = 2 + (3.4+6)

Now, for any 3 terms a, b and c the given properties in the options are described as:

1. Associative Property of Addition

(a +b) + c = a + (b + c)

2. Commutative Property of Multiplication

a x b = b x a

3. Inverse Property of Multiplication

[tex]a \times \frac{1}{a} = 1[/tex]

4. Commutative Property of Addition

a+ b = b + a

Hence, from the given expression,we can see that:

(2+3.4) + 6 = 2 + (3.4+6)

⇒(a +b) + c = a + (b + c)

Hence, the expression represents the Associative Property of Addition

Final answer:

The statement (2+3.4) + 6 = 2 + (3.4+6) demonstrates the Associative Property of Addition, indicating that the sum of a set of numbers is the same regardless of how the numbers are grouped.

Explanation:

The property illustrated by the statement (2+3.4) + 6 = 2 + (3.4+6) is the Associative Property of Addition. This property states that when adding three or more numbers, the way in which the numbers are grouped does not change the sum. For instance, as shown in the statement, (a + b) + c equals a + (b + c), which means that the groupings of the numbers can be changed without affecting the total sum. This is not to be confused with the Commutative Property of Addition, which is about the order of the numbers and states that A + B equals B + A. The commutative property tells us that we get the same result whether we add 2 + 3 or 3 + 2. However, the question explicitly deals with the grouping of numbers, not the order, thus confirming that the associative property is in use.

Step-by-step explanation:

An integer is a number that can be written without a fractional component.

Answer:

[tex]\text{Shaded area as fraction}=\frac{81}{100}[/tex]

[tex]\text{Shaded area as decimal}=0.81[/tex]

[tex]\text{Shaded area as percent of the whole}=81\%[/tex]

Step-by-step explanation:

Please consider the attached image as the given square.

We are asked to express the shaded area as a fraction, a decimal, and a percent of the whole.

We can see that in our figure there are 100 squares as there are 10 rows and each row contains 10 squares.

We can also see that there are 81 shaded squares out of 100 squares, so we can represent it as a fraction as:

[tex]\frac{\text{Shaded squares}}{\text{Total squares}}[/tex]

[tex]\text{Shaded area as fraction}=\frac{81}{100}[/tex]

To convert the shaded area into decimal, we need to divide 81 by 100.

[tex]\text{Shaded area as decimal}=0.81[/tex]

To convert the shaded area into percent, we need to multiply 0.81 by 100.

[tex]\text{Shaded area as percent of the whole}=0.81\times 100\%[/tex]

[tex]\text{Shaded area as percent of the whole}=81\%[/tex]

The fraction is: 44/100

The Decimal is: 0.44

Percent: 44%

Answer:

4 polio

56 measles

Step-by-step explanation:

Write equations to represent the problem

let x be the number of vaccinations for polio

let y be the number of vaccinations for measles

x + y = 60          Equation for vaccinations

4x + 2y = 128    Equation for doses

Solve the system using substitution. Rearrange x + y = 60 to isolate one variable.

x = 60 - y

Substitute x for 60-y in the other equation

4x + 2y = 128

4(60-y) + 2y = 128     Distribute over brackets

240 - 4y + 2y = 128    Collect like terms. They have the variable "y"

240 - 2y = 128    Subtract 240 from both sides

-2y = 128 - 240

-2y = -112    Divide both sides by -2

y = -112/-2

y = 56    Number of measles vaccinations

Substitute y for 56 in x + y = 60

x + y = 60

x + 56 = 60

x = 60 - 56

x = 4   Number of polio vaccinations

Therefore Dr. Potter gave out 4 polio vaccinations and 56 measles vaccinations.

Answer:

DZ = 4 units

Step-by-step explanation:

Given:

CD || XZ

YC = 25 units, CX = 5 units, YD = 20 units.

We know that,

If CD is parallel to XZ , then the line CD divides the sides XY and YZ of the triangle XYZ proportionally. This is true by triangle proportionality theorem.

Therefore, the lengths YC, CX, YD and DZ are in proportion. This gives,

[tex]\frac{YC}{CX}=\frac{YD}{DZ}[/tex]

Rewrite in terms of DZ. This gives,

[tex]DZ=\frac{YD\times CX}{YC}[/tex]

Plug in [tex]YC=25,CX=5,YD=20[/tex]. Solve for DZ.

[tex]DZ=\frac{20\times 5}{25}\\\\DZ=\frac{100}{25}=4[/tex]

Therefore, the length of DZ is 4 units.
