Answer:

16

Explanation:

Area of Triangle = 1/2(B*H)

Height - 4

Base - 8

8 * 4 = 32

32 / 2 = 16

16 because the base is 8 and the height is 4. That equals 32. 32/2=16

Fiona wrote the linear equation y = 2/5 x – 5. When Henry wrote his equation, they discovered that his equation had all the same

Hoochie [10]

we have

$y=\frac{2}{5}x-5$

Let's Isolate the variable y in each of the cases and then compare with Fiona's equation to determine the solution of the problem

case A) $x-\frac{5}{4}y= \frac{25}{4}$

Multiply by $4$ both sides

$4x-5y= 25$

$5y=4x-25$

Divide by $5$ both sides

$y=\frac{4}{5}x-5$

therefore

the case A) is not equal to Fiona's equation

case B) $x-\frac{5}{2}y= \frac{25}{4}$

Multiply by $4$ both sides

$4x-10y= 25$

$10y=4x-25$

Divide by $10$ both sides

$y=\frac{2}{5}x-2.5$

therefore

the case B) is not equal to Fiona's equation

case C) $x-\frac{5}{4}y= \frac{25}{2}$

Multiply by $4$ both sides

$4x-5y= 50$

$5y=4x-50$

Divide by $5$ both sides

$y=\frac{4}{5}x-10$

therefore

the case C) is not equal to Fiona's equation

case D) $x-\frac{5}{2}y= \frac{25}{2}$

Multiply by $2$ both sides

$2x-5y= 25$

$5y=2x-25$

Divide by $5$ both sides

$y=\frac{2}{5}x-5$

therefore

the case D) is equal to Fiona's equation

the answer is

$x-\frac{5}{2}y= \frac{25}{2}$

One of the skylights on the roof of Bianca’s building is in the shape of the solid below.

luda_lava [24]

Answer:

588 sq. in.

Step-by-step explanation:

The total volume of air inside the skylight is in the shape of a pyramid, not the rectangular prism at the bottom.

So, if we look at the pyramid, it has a square base with dimensions 14 x 14. Its height is 11 - 2 = 9.

Formula for volume of a pyramid is:

V = 1/3 * Area of Base * height

Area of Base (since it is a square) = 14 * 14 = 196

Height is 9

plugging into the formula, we get:

$V=\frac{1}{3}*BaseArea*height\\=\frac{1}{3}*196*9\\=588$

Hence, volume is 588 sq. in.

If you can solve 20 multiplication facts in one minute how long will it take to solve 50 facts

mezya [45]

Answer:

150s or 2 min and 30 s

Step-by-step explanation:

20 facts = 1 min

10 facts = 30s

50 facts = ? min

50 / 10 = 5

30 * 5 = 150s

150s = 2 min and 30 s
