Answer:

9\picentimeters squared or 28.27 centimeters squared

Step-by-step explanation:

The formula for volume is r^{2} \pi h. The radius is 3 and the height is 1 so it is 3^{2} \pi 1 which equals 9\pi. 9\pi is roughly 28.27.

Which rule represents the translation from the pre-image, ΔABC, to the image, ΔA'B'C'?
cluponka [151]

The rule represents the translation from the pre-image, ΔABC, to the image, ΔA'B'C' is (x, y) → (x + 7, y - 6).

<h3>What is translation?</h3>

When a line is translated, it means the line is moved from one position to another. The coordinate for triangle ABC are A(-3 ,4) , B(-4,1) and C(-2,1).

The coordinate of triangle A'B'C' is A'(4,-2), B'(3,-5), and C'(5,-5).

From above, it can be seen that the image A'B'C' is obtained from the pre-image ABC by translating the vertices of the image by 7 units to the right and 6 units down.

Therefore, the rule represents the translation from the pre-image, ΔABC, to the image, ΔA'B'C' is (x, y) → (x + 7, y - 6)

Hence, the rule represents the translation from the pre-image, ΔABC, to the image, ΔA'B'C' is (x, y) → (x + 7, y - 6).

If x to y as 4 is to 5 then what is y:x Please solve mark brainliest
Radda [10]

Answer:

y : x: = 5 : 4

Step-by-step explanation:

x to y = 4 to 5

Rewrite;

x:y = 4:5

Remember, a ratio is another way of representing a fraction, hence one can do the same operations that one could do with a fraction. Therefore, one can take the cross products of a ratio;

x : y= 4 : 5

5x = 4y

Inverse operations;

5x = 4y

x = \frac{4}{5}y

Now substitute this into the equation y:x

y : \frac{4}{5}y

Rewrite as a fraction;

\frac{y}{\frac{5}{4}y}

Simplify;

\frac{1}{\frac{4}{5}}\\\\\frac{5}{4}

Rewrite as a ratio;

y : x = 5 : 4

When x, is 0, you just have to plug in 0 for x (and solve for y):
y = -2(0)+1
y = 1

So, your answer: y = 1

A football team receives a 5-yard penalty on one play and a 10-yard penalty on the next. Write a number sentence to represent th
DanielleElmas [232]

Answer: Total penalty =  -5yd + (-10yd) =  -15yd

Step-by-step explanation:

A number sentence is any type of equation that represents something:

First, the team receives a 5 yd penalty.

-5yd

Then the team receives another penalty, this time of 10 yd, then we can write the total penalty as the sum of the two penalties.

Total penalty =  -5yd + (-10yd) =  -15yd
