Answer:

22 kids

Step-by-step explanation:

R (red shirts)

Y (yellow shirts)

R= Y+12 (to make them equal, you need to add 12 to the yellow because it tells you that there are 12 more red shirts than yellow)

R+Y=32 (the amount of students in the class)

Substitute R from the first equation into the second one.

(Y+12) + Y = 32

2Y +12 =32 (subtract 12 from both sides)

2Y =20 (divide by 2 on both sides)

Y=10

Now you know the amount of kids wearing yellow shirts.

Subtract the whole class and the yellow shirts.

32-10= 22

A certain forest covers an area of 2100 km^2. Suppose that each year this area decreases by 5.25%. What will the area be after 6

Neko [114]

Answer:

The area after 6 years is $1519.49km^2$

<em></em>

Step-by-step explanation:

Given

$a = 2100$ --- Initial Value

$r = 5.25\%$ --- Rate

Required

Determine the area after 6 years

Because the area reduces,, the following formula will be used to solve the question.

$y = a*(1 - r)^t$

Here

$t = 6$

So, we have:

$y = 2100*(1 - 5.25\%)^6$

Convert percentage to decimal

$y = 2100*(1 - 0.0525)^6$

$y = 2100*(0.9475)^6$

$y = 1519.47866516$

$y = 1519.49$ -- approximated

<em>The area after 6 years is </em> $1519.49km^2$ <em></em>

Find the value of x that makes line m parallel to line n.

evablogger [386]

Answer: <em>x</em> = 20

Step-by-step explanation:

If line <em>m</em> is parallel to line <em>n</em>, the two angles given will be congruent because they will be alternate exterior angles (which are congruent).

This means we will set them equal to each other and solve for <em>x</em>.

Given:

(4<em>x</em> - 23) = (2<em>x</em> + 17)

Add 23 to both sides of the equation:

4<em>x</em> = 2<em>x</em> + 40

Subtract 2<em>x</em> from both sides of the equation:

2<em>x</em> = 40

Divide both sides of the equation by 2:

<em>x</em> = 20

A golf player is trying to make a hole-in-one on the miniature golf green shown.

Flauer [41]

The path of the ball is an illustration of absolute equation.

The equation of the path is: $y =- \frac{12}7|x- 4.8| + 6.4$

The given parameters are:

$(h,k) = (4.8,6.4)$ --- the vertex (i.e. the point where the ball hits the wall)

$(x_1,y_1) = (2,1.6)$

$(x_2,y_2) = (7.6,1.6)$

An absolute function is represented as:

$y = a |x - h| + k$

Substitute $(h,k) = (4.8,6.4)$

$y = a |x - 4.8| + 6.4$

Substitute $(x_1,y_1) = (2,1.6)$ for x and y

$1.6 = a|2 - 4.8| + 6.4$

$1.6 = a|- 2.8| + 6.4$

Remove absolute bracket

$1.6 = 2.8a + 6.4$

Collect like terms

$2.8a = -6.4+1.6$

$2.8a =- 4.8$

Solve for a

$a =-\frac{4.8}{2.8}$

Simplify

$a =-\frac{12}{7}$

Substitute $a =-\frac{12}{7}$ in $y = a |x - 4.8| + 6.4$

$y =- \frac{12}7|x- 4.8| + 6.4$

Hence, the equation of the path is: $y =- \frac{12}7|x- 4.8| + 6.4$

See attachment for graph that models the path
