Answer:

9 in³

Step-by-step explanation:

The volume (V) of the pyramid is calculated as

V = $\frac{1}{3}$ Ah ( A is the area of the base and h the perpendicular height )

A = 3 × 3 = 9 in² ← area of base and h = 3, thus

V = $\frac{1}{3}$ × 9 × 3 = 3 × 3 = 9 in³

Simplify 5 square root of 7 end root plus 12 square root of 6 end root minus 10 square root of 7 end root minus 5 square root of

Alinara [238K]

Answer:

So, the simplified version is

$-5\sqrt{7}+7\sqrt{6}$

In words it can be written as minus 5 square root of 7 end root plus 7 square root of 6 end root

Step-by-step explanation:

$5\sqrt{7}+12\sqrt{6}-10\sqrt{7}-5\sqrt{6}$

We need to simplify the above expression.

Combining the like terms of the above expression.

Like terms are those that have same variables.

$=(5\sqrt{7}-10\sqrt{7})+(12\sqrt{6}-5\sqrt{6})$

$=((5-10)(\sqrt{7})+((12-5)(\sqrt{6}))$

$=((-5)(\sqrt{7})+((7)(\sqrt{6}))$

So, the simplified version is

$-5\sqrt{7}+7\sqrt{6}$

In words it can be written as minus 5 square root of 7 end root plus 7 square root of 6

Candace makes a sugar-water mixture for hummingbirds. She knows the amount of sugar used in the mixture is proportional to the a

Sonja [21]

Answer:

the first image (the image with the upward sloping line)

Step-by-step explanation:

If the amount of sugar used in the mixture is proportional to the amount of water used, as more water is used, the more sugar is used. So, as more water is used, more sugar is used.

If the amount of water used is constant regardless of the amount of sugar, the appropriate graph would be the second graph. the graph with the straight line

Which line has the same slope as the line passing through (-4,-1)and (-1,8)?

marusya05 [52]

Answer:

A: 9x-3y =5

Step-by-step explanation:

slope of the line = (8-(-1))/(-1)-(-4) = 3

so y = mx+ c , where m= slope

the equation 9x-3y= 5 has the slope 3 since we can make y the subject of the formula to get

y= 3x - 5/3..here m is also equal to 3
