Answer:

Step-by-step explanation:

Each of the squares has trinomials that factor. x^2 - 14x + 49 = (x - 7)^2

When you take the square root (to get the side length) you get x - 7. So the length of each square is x - 7) = 0;..........x=7 That's the answer to a.

The answer to b is the same. The width =7

It's a square both sides have to be equal.  

The length of the rectangle when the two squares are put together is 7 +7 = 14.

Answer: Question a = 7..... Question b = 7 ......... Question C = 14

Grant has $58 in a savings account. He plans on depositing $30 into the
account each month and not taking any money out of the account. Which
function rule will give the total amount T that he has in the account
after n months?

Answers

Answer

I believe it is the first answer

Step-by-step explanation:

You would have to multiply 30 by however many months he deposits money to find how much he has in he account at that time

Hope this helps

The function rule of the total amount T in the account after n months is

T = 30n + 58.

Option A is the correct answer.

What is an expression?

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Amount in the account = $58

Amount deposited each month = $30

The total amount after n months.

T = 58 + 30n

Thus,

The T = 30n + 58 is the total amount in the account after n months.

At every company meeting, the president speaks for 28 minutes and then takes questions from her employees. Let q represent the number of minutes she spends answering questions and t represent the total number of minutes the meeting lasts.

Answers

Answer:

t = 20 + q in minutes

Step-by-step explanation:

Company meeting = president speech + questions + answers

President speech = 20 minutes

Questions and answers = q minutes

Total time spent = t minutes

Total time spent = President speech + Total time spent

t = 20 + q

The equation that represents the relationship between q and t is

t = 20 + q in minutes

Sam and Taylor own and operate a car wash service. Sam cleans the interior of each car and Taylor cleans the exterior. The time it takes Sam to finish the interior has a mean of 20 minutes with a standard deviation of 6.4 minutes. The time it takes Taylor to finish the exterior has a mean of 18 minutes with a standard deviation of 4.8 minutes. Both of their finishing times are approximately normally distributed.
Suppose we select a car at random, and define the random variable D as the difference between their finishing times. We can assume that their times are independent.
Find the probability that they finish within 10minutes of each other.

Rewrite the sum of 75+18 as a product of a number and another sum

Answers

Answer:

(2)(9) + 75 = 75+18

Step-by-step explanation:

(2)(9) + 75 = 75+18

The expression written as a product of a number and another sum is 3(25 + 8)

Given the expression 75 + 18, we are to write as a product of a number and another sum.

First we need to find the GCF of 75 and 18

75 = 3 * 25

18 = 3 * 6

Since 3 is common to both D+GCF, we can factor it out from the expression to have:

75 + 18 = 3(25 + 8)

Hence the expression written as a product of a number and another sum is 3(25 + 8)

1. If RU = 16, UT = 20, and SR = 16, what is the perimeter of SUT?
Figure:
Please answer ASAP!

Answers

Answer:

72

Step-by-step explanation:

If SR and RU have the same length, a right angle, and a shared side, we know that they are congruent triangles using SAS (Side Angle Side). Our equation to find the perimeter would be SR + RU + UT + TS or 16 + 16 + 20 + 20(using our knowledge of the congruent triangles) = 72.

The Perimeter of SUT is 72 units.

What is Pythagoras theorem?

According to the Pythagoras theorem, the square of the hypotenuse of a triangle, which has a straight angle of 90 degrees, equals the sum of the squares of the other two sides.

Given:

RU = 16, UT = 20, and SR = 16

Now, Using Pythagoras theorem

UT² = RT² + RU²

20²= RT² + 16²

RT² = 400- 256

RT² = 144

RT= 12

And, ST=20

Now, Perimeter of SUT

= 16 + 16 + 20 +20

= 72

Triangle ABC is an obtuse triangle with the obtuse angle at vertex B. Angle A must be

less than 90°.
greater than 90°.
congruent to angle B.
congruent to angle C

Answers

Answer:

"less than 90°."

Step-by-step explanation:

This is because an obtuse triangle can be defined as "An obtuse triangle (or obtuse-angled triangle) is a triangle with one obtuse angle (greater than 90°) and two acute angles." Therefore, there can only be ONE obtuse angle. Therefore, with the obtuse angle being at vertex B, there cannot be another one at vertex A.
