Help now please I’ve been sitting here for 20 minutess

Answer:

Step-by-step explanation:

Number of laps run by Runner A = x

Number of laps run by Runner B = y

Runner B ran 6 more than twice as many laps as Runner A.

b = 6 + 2a

Together they ran a total of 30 laps.

a + b = 30

Part A: Write an equation for this situation. Use a variable to represent the number of laps for Runner A.

Part B: How many laps did Runner A run?

a + b = 30

b = 6 + 2a

Hence:

a + 6 + 2a = 30

3a = 30 - 6

3a = 27

a = 27/3

a = 9 laps

Part C: How many laps did Runner B run?

a + b = 30

b = 30 -9

b = 21 laps

Answer:

15/56

Step-by-step explanation:

42*4n=45

4n=45/42

4n=15/14

n=(15/14)/4

n=(15/14)(1/4)

n=15/56

Answer:

Step-by-step explanation:

42 ⋅ 4n = 45

4n= 45/42 = 15/14

n = 15/14/4 = 15/56

Answer:

B. 81 in.²

Step-by-step explanation:

We have been given that the trapezoid shown in the attachment has been enlarged by a scale of 1.5. We are asked to find the area of the enlarged trapezoid.

The area of the original trapezoid is 36 square inches.

Since each side of the trapezoid is enlarged 1.5 times, so the area of new trapezoid would be 2.25 times greater than area of original trapezoid.

The area would be 2.25 times greater because area is product of sum of lengths of parallel sides and height.

1.5 × 1.5 = 2.25

Area of new trapezoid: 2.25 × 36 in²

Area of new trapezoid = 81 in²

The area of the enlarged trapezoid would be 81 in² or option B.

Answer:

Answer:

[tex]Probability = \frac{11}{40}[/tex]

Step-by-step explanation:

Given

See attachment

Required

The probability that a 7th grader selected will play guitar.

From the attachment, we have:

[tex]7th\ graders =11+8+8+13[/tex]

[tex]7th\ graders =40[/tex]

7th graders that can play guitars are:

[tex]Guitars = 11[/tex]

So, the probability is:

[tex]Probability = \frac{Guitars}{7th\ graders}[/tex]

[tex]Probability = \frac{11}{40}[/tex]

Answer:

yx

Step-by-step explanation:

The answer is yx

We can draw the conclusion that linear functions can be used to represent each of the ideas. Due to the fact that each proposal's linear function has an initial value, the class now has money in its accounts (b).

A linear function is denoted by the equation y = mx + b, where m is the slope or unit rate between the two variables, x and y, and b is the beginning value or y-intercept.

The initial value is b.

A linear function is a graph with straight lines.

A unit rate exists for all linear functions (b).

here, we have,

given that,

Sarah's suggestion can be expressed by a linear function because the graph that represents it is a straight line.

Gene's Proposal's table displays the unit rate as change in y/change in x = 7. As a result, a linear function can be used to express it.

Paul's idea has a linear function as its equation.

This leads us to the conclusion that linear functions can be used to represent each of the ideas.

Due to the fact that each proposal's linear function has an initial value, the class now has money in its accounts (b).

Step-by-step explanation:

Answer:

Step-by-step explanation:

x        - the measure of the largest angle

x - 107°        - the measure of the smallest angle

¹/₃x     - the measure of the third angle

x + x - 107° + ¹/₃x = 180°

2¹/₃x = 180° + 107°

⁷/₃x = 287°

x = 287°÷⁷/₃

x = 287° · ³/₇

x = 123°

x-107° = 123° - 107° = 16°

¹/₃x = ¹/₃ · 123° = 41°

Answer:

x = 60

largest angle = 80°

Step-by-step explanation:

the sum of all three angles in a triangle = 180°

(3x - 100) + (x - 10) + (x - 10) = 180

simplify:

5x = 300

x = 60

angles are 80°, 50°, and 50°

Answer:To calculate the standard deviation of those numbers:

1.Work out the Mean (the simple average of the numbers)

2.Then for each number: subtract the Mean and square the result.

3.Then work out the mean of those squared differences.

4.Take the square root of that and we are done!

Answer:

[tex]V=502.5\ cm^3[/tex]

Step-by-step explanation:

The area of the pentagonal base, A = 33.5 cm²

The height of the prsim,h = 15 cm

We need to find the volume of the pentagonal base prism. The formula for the volume of the pentagonal base prism is given by :

[tex]V=A\times h\\\\V=33.5\times 15\\\\V=502.5\ cm^3[/tex]

So, the required volume is [tex]502.5\ cm^3[/tex].

Answer:

The answer is B. [tex]3\frac{1}{3} ft.[/tex]

Step-by-step explanation:

It states that the figures in the pair are similar

When you multiply 5*8 it gives you 40 on the first angle

If the figures are similar then the other angle will equal 40.

So we need to find out which number that is multiplied by 12 that will give you 40.

If we multiply [tex]12*3\frac{1}{3}[/tex], it should  give you 40.

Convert The mixed number into a improper fraction:

3 1/3=3*3+1/3

=10/3

Convert the element into a fraction:

12/1*10/3

Factor the number:

3*4/1=10/3

Cross - cancel the common factor: 3

4/1*10/1

Apply the fraction rule:

4*10/1*1

Multiply the numbers: 4*10=40

=40/1*1

Multiply the numbers: 1*1=1

=40/1

Apply the Fraction rule:

=40
