Answer:

50m²

Explanation:

first, we have to find the length and width of the backyard. since 4cm represents 5m, we know that the real width of the backyard is 5m.

as for the length of the backyard, 8cm is double of 4cm so we can also double 5m to get 10m.

now, we can find the area by taking 5m × 10m = 50m².

i hope this helps! :D

Han and Tyler are following a polenta recipe that uses 5 cups of water for every 2 cups of cornmeal.

Aleonysh [2.5K]

Answer:

Step-by-step explanation:

1. 5 cups of cornmeal=2 cups of water. Using 115 cups of cormeal would mean you need 287.5 cups of water, not 3.

3 is too little

2: If you use 5 cups of water for every 3 cups of cornmeal, for 3 cups of cornmeal you'd need like 6.5 cups of water, not that high of a number.

Natasha_Volkova [10]

Answer:

60 inches long are the sides of the pillars.

Step-by-step explanation:

Given : A small bridge sits atop four cube shaped pillars that all have the same volume. the combined volume of the four pillars is 500 ft cubed.

To find : How many inches long are the sides of the pillars?

Solution :

Refer the attached picture below for Clarence of question.

The volume of the cube is $V=a^3$

Where, a is the side.

The combined volume of the four pillars is 500 ft cubed.

The volume of each cube is given by,

$V=\frac{500}{4}=125\ ft^3$

Substitute in the formula to get the side,

$125=a^3$

$a=\sqrt[3]{125}$

$a=5\ ft$

We know, 1 feet = 12 inches

So, 5 feet = $5\times 12=60$ inches

Therefore, 60 inches long are the sides of the pillars.

Evaluate each expression. Determine if the final simplified form of the expression is positive or negative -42 (-4)2 42

Sati [7]

Answer:

Given the expression:

$-4^2$

we know:

$4^2 = 4 \times 4 = 16$

then;

$-4^2 = -16$

Therefore, the value of expression $-4^2$ is -16 i.e negative.

$(-4)^2$

we know:

$4^2 = 4 \times 4 = 16$

$(-1)^2 = 1$

then;

$(-4)^2 = (-1)^2 \cdot (4)^2= 16$

Therefore, the expression $(-4)^2$ is 16 i.e Positive.

$4^2$

we know:

$4^2 = 4 \times 4 = 16$

then;

$4^2 = 16$

Therefore, the expression $4^2$ is 16 i.e Positive.
