Answer:

5/8

Step-by-step explanation:

First we need to figure out how many girls  and boys there are.

g = girls

b = boys

g = b+8  ( eight more girls than boys)

b = g-8

There are 32 students)

g+b =32

Substitute b = g-8 into the equation

g + (g-8) = 32

Combine like terms.

2g-8 = 32

Add 8 to each side.

2g -8+8 = 32+ 8

2g = 40

Divide by 2

g = 20

There are 20 girls

The experimental probability of picking a girl is

girls/ total

20/32 = 5/8

Finding the volume of this will mean that we'll have to know the formula. The formula for finding the volume of a prism is L x W x H. 
L- Lenght
W - Width
H - Height.

So Volume is going to be equalled to  6 x 5 x 4 = 120 cm cubed

A recipe uses 2 cups of flour to make 18 cupcakes. How much flour is needed to make 27 cupcakes?
drek231 [11]

Answer:

3 cups

Step-by-step explanation:

we can solve this by setting up ratios

\frac{2 cups}{18 cupcakes} = \frac{x}{27 cupcakes}

cross multiply:

(2)(27) = 18x

54 = 18x

solve for x

x = 3 cups

What is the value for y
egoroff_w [7]

Answer:

y = 107°

Step-by-step explanation:

As you can see from the markings on the triangle, this is an isosceles triangle (two sides are congruent).

An isosceles triangle has the base angles congruent too.

So at this point,

34 = x - 5

Solve for x,

34 = x - 5

x = 34 + 5

x = 39

Now, the total angle measure of triangle is 180°.

There are two angles ready to solve for y.

34 + 39 + y = 180

73 + y = 180

y = 180 - 73

y = 107°

Don’t understand 23 and 24
enot [183]

Answer:

23.  16x² + 4x + 0.25

24.  16x² - 4x + 0.25

Step-by-step explanation:

Given the functions f(x) = 4x + 0.5 and g(x) = 4x - 0.5, questions 23 and 24 are asking you to square the entire function.  So, you will take the expression given in each function and square it:

(f(x))² = (4x + 0.5)(4x + 0.5) Using FOIL:

(4x*4x) + (4x*0.5) + (4x*0.5) + (0.5*0.5)

16x² + 2x + 2x + 0.25 = 16x² + 4x + 0.25

(g(x))² = (4x - 0.5)(4x - 0.5) Using FOIL:

(4x*4x) - (4x*0.5) - (4x*0.5) + (0.5*0.5)

16x² - 2x - 2x + 0.25 = 16x² - 4x + 0.25
