Answers

You do 12.4 x 97.02 because that’s already length times width, and all you need to do is multiply the height.

Once you do that, you get 1,203.048,

then you divide that by 3 and you get 401.016

And that rounds to 401.1 ig

"what is the value of a in the equation 81^b=a^4b"

Answers

Answer:

Step-by-step explanation:

The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.

What is an expression?

Mathematical expression is defined as the collection of the numbers variables and functions by using operations like addition, subtraction, multiplication, and division.

Given that;

The expression is,

⇒ [tex]81^b = a^4^b[/tex]

Now,

Solve the expression for the value of b as;

⇒ [tex]81^b = a^4^b[/tex]

Since, 81 = 3⁴

So, We get;

⇒ [tex]3^4^b = a^4^b[/tex]

By comparing, we get;

⇒ a = 3

Thus, The value of a in the equation [tex]81^b = a^4^b[/tex] will be 3.

Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'. Which rule describes this transformation?
A: (x, y) → (x−5, y−3)
B: (x, y) → (x+5, y+3)
C: (x, y) → (x−3, y−5)
D: (x, y) → (x+3, y+5)

Answers

Answer:

B

Step-by-step explanation:

As Quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P′Q′R′S′.

Therefore, we can conclude that the rule '' A rule for a translation right and up (x + __, y + __) '' describes this transformation.

The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.

Given that, quadrilateral PQRS was translated 5 units to the right and 3 units up to create quadrilateral P'Q'R'S'.

What is the translation?

A translation in math moves a shape left or right and/or up or down. The translated shapes look exactly the same size as the original shape, and hence the shapes are congruent to each other. They just have been shifted in one or more directions.

Translation rules:

When the shape is moved towards the right by k units, then replace x with x + k.

When the shape is moved up by k units, then replace y with y + k.

So, translated 5 units to the right

x → x+5

Translated 3 units up

y → y+3

The transformation which describes the quadrilateral P'Q'R'S' is (x, y) → (x+5, y+3). Therefore, option B is the correct answer.

What is the circumference and area of both pizzas?
will mark brainliest

Answers

To find circumference, you must multiply the diameter by pi, (roughly 3.14)
To find area, you can use the formula A=pi (radius) squared
Radius is half of diameter

For the large pizza, the circumference would be about 50.265. You can round this to ~50 inches.
The area would be about 201.06 inches. You can round this to 201 inches


For the medium pizza, the circumference would be about 37.69 inches. The area would be about 113.09 inches squared.

Answer: C) 35

Explanation: To solve you must follow the rules of PEMDAS.
First, we divide and multiply, left to right.
22/11 = 2
Then, we have another at the end of the equation.
11 x 3 = 33
Now we are left with 2+33.
Which leaves us with 35.

A six-week fitness program was designed to decrease the time it takes retired individuals to walk one mile. At the beginning of the program, 20 randomly selected retired individuals were invited to participate, and their times to walk a mile were recorded. After the six-week program, their times to walk a mile were again recorded. Most participants saw little to no improvement in their times to walk one mile; however, a few participants saw drastic improvements in their times to walk one mile. The program director would like to perform a hypothesis test to determine if the program reduces the mean time for retired individuals to walk a mile. Which of the following statements is true? a. Because there are 40 observations in total, the sample size is large enough to assume that the sampling distribution of the sample mean differences is approximately normal. b. Because the walk times before and after the program are paired, a hypothesis test is not appropriate. c. The sampling distribution of sample means can be assumed to be approximately normal because the distribution of the sample data is not skewed. d. Because the sample size of 20 is less than 30 and the improvements in walk times in the sample data appear to be skewed, the distribution of sample means should not be assumed to be approximately normal. e.
