Diana has an end table in the shape of a right triangle. The triangular tabletop is twice as high as it is wide at the base. If

n200080 [17]

Answer:

The width of the base is 2.828 feet

Explanation:

Given the area of the table top is 4 square feet

The triangular table top is twice as high as it is wide at the base

Therefore, we can say that height = base

Area of a right angled triangle is calculated by, Area = ½ * base * height

In this case, height = base

Therefore, area = $\frac{1}{2}\times (base)^2$

Substituting the values,

4 = $\frac{1}{2}\times (base)^2$

$(base)^2$ = 8

Base = 2√2 = 2 * 1.414 = 2.828 feet

Therefore, the width of the base is 2.828 feet

Angelina has five cakes. She wants to cut them into 2/5 pieces. How many pieces will she be able to cut?

Licemer1 [7]

Answer:
She will be able to cut them into 12.5 pieces

Explanation:
We know that the total number of cakes is 5 cakes and that the portion of each piece would be $\frac{2}{5}$ .

To know the total number of pieces she can divide, we would simply divide the total number of cakes by the portion of each cake as follows:
number of pieces = $\frac{5}{ \frac{2}{5}}$

number of pieces = $\frac{25}{2}$

number of pieces = 12.5 pieces

Hope this helps :)

Let's put it in slope intercept form

2y = x - 14

y = (1/2) x - 7

[ ] Slope = 2. Nope, slope=1/2

[ ] y intercept = 7. Nope, y intercept = -7

[ ] line moves up from left to right. Positive slope, that's TRUE

[ ] x intercept is positive.
