Answer:

12

Step-by-step explanation:

We just need to divide the number of laps to the number of swimmers to find the unit rate.

240 / 20 = 12

216 / 18 = 12

168 / 14 = 12

108 / 9 = 12

X = amount of forks bought

y = amount of spoons bought

Answer:

Yes, it should work.

Step-by-step explanation:

DC=AB  (because it is a rectangle and they are parallel)

DA=CB (because it is a rectangle and they are parallel)

DB=AC (given)

Those are all sides and gives enough information for us to know that it is congruent.

Answer:

Step-by-step explanation:

T=L(8+RS)

T=L8+LRS

T-L8=LRS

R=T-L8/LS

The required solution to the given equation is R = (T - 8L)/LS.

The equation is defined as a mathematical statement that has a minimum of two terms containing variables or numbers that are equal.

The equation is given in the question, as follows:

T = L(8 + RS)

Apply the distributive property of multiplication,

T = L × 8 + L × RS

T = 8L + LRS

Rearrange the terms in the above equation,

T - 8L = LRS

Divided by LS into both sides, and we get

R = (T - 8L)/LS

Thus, the required solution to the given equation is R = (T - 8L)/LS.

Answer:

$913.46

Step-by-step explanation:

$47,500 / 52 = 913.46

Given:

Number of rows = 3

Number of columns = 6

Number of square boxes = 18

yellow square boxes in the top two rows = 12

Blue square boxes in the first 5 columns = 15

Number of green boxes (shading overlaps) = 10

To find:

The model to show multiplying a fraction by a fraction.

Solution:

2 rows out of 3 are shaded yellow.

Fraction for yellow = [tex]\dfrac{2}{3}[/tex]

5 columns out of 6 are shaded blue.

Faction for blue = [tex]\dfrac{5}{6}[/tex]

10 out of 18 squares are green.

Faction for green =  [tex]\dfrac{10}{18}=\dfrac{5}{9}[/tex]

Now,

[tex]\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{10}{18}[/tex]

[tex]\dfrac{2}{3}\times \dfrac{5}{6}=\dfrac{5}{9}[/tex]

Therefore, the correct option is D.

The correct option is D.

2 rows out of 3 are shaded yellow.

Fraction should be [tex]2\div 3[/tex]

Now

5 columns out of 6 are shaded blue.

Fraction should be [tex]5 \div 6[/tex]

And,

10 out of 18 squares are green.

Fraction should be  [tex]10 \div 18 = 5\div 9[/tex]

Now

[tex]\frac{2}{3} \times \frac{5}{6} = \frac{10}{18}\\\\ \frac{2}{3} \times \frac{5}{6} = \frac{5}{9}[/tex]

Work Shown:

y-5 = x^2

y = x^2 + 5 ... add 5 to both sides

y = 1x^2 + 5

y = 1(x-0)^2 + 5 ... x replaced with (x-0)

The equation is now in the form y = a(x-h)^2 + k

We have a = 1, h = 0, k = 5.

The vertex is (h,k) = (0,5)

The value of 'a' determines how vertically stretched or compressed the parabola is. Also, if a > 0, then the parabola opens upward; or if a < 0, then the parabola opens downward.

Answer: 10

Step-by-step explanation:

The x-intercepts means when y equals 0, or when the function crosses the x-axis.

0 = (x-6)^2 - 16

16 = (x-6)^2

Take the square root of both sides:

4 = (x-6)

Add 6 to both sides to get:

x = 10

Answer:

Independent variable: distance

Dependent variable: number of letters recognized on an eye chart

Step-by-step explanation:

Independent variables are stand-alone. This means that it does not depend on another variable but affects the dependent variable.

Dependent variables are dependent on another variable. When the independent variable changes, dependent variables are changed.

Since the hypothesis is that the distance affects the number of letters recognized,

the distance causes a change in the number of letters recognized not the other way around.

Thus, the dependent variable is the number of letters recognized on the eye chart while the independent variable is the distance.

Answer:

The equation has an Inifinite amount of solutions

Step-by-step explanation:

2 ( 3g + 2 ) = 1/2 ( 12g + 8 )

First use the distributive property of multiplication -

6g + 4 = 6g + 4

6g cancels out from both sides of the equation -

4 = 4

When both sides of an equation are the same there is an infinite amount of solutions.

f=39

Step-by-step explanation:

hi! first, we can multiply by 12 on both sides to eliminate the 12 in the denominator.

f+3= (7/2)*12

f+3=84/2

f+3=42

now, subtract 3 on both sides.

f=39
