x=7

Step-by-step explanation:1,200x 0.06 interest= 72.

She paid it over the course of 9 months, so 72x9= 648.

Mira pay $1,254 the bank back all together.

A quick and easy method of calculating the interest charge on a loan is called a Simple interest.

We have to given that;

Mira borrowed $1,200 from the bank to help pay rent.

And, The bank charged 6% interest over 9 months.

Now, We know that;

⇒ Simple interest = PRT / 100

Where, P is principle amount, R is rate and T is time.

So, We get;

⇒ Simple interest = PRT / 100

⇒ Simple interest = 1200 × 6 × 9/12 × 1/100

⇒ Simple interest = $54

Hence, The total amount to pay back to bank is,

⇒ Amount = Principle amount + Interest

⇒ Amount = $1,200 + $54

⇒ Amount = $1,254

The answer would be -3.

Answer:

110 in.

Step-by-step explanation:

newspapers have four sides because it is a square

one side is parallel to the other side.

so

20 × 2 for the width

35 × 2 for the height

20 × 2 = 40

35 × 2 = 70

add together for the perimeter.

40 + 70 = 110 in.

you could also...

20 + 35 + 20 + 35 = 110 in.

Answer:

C. 5, 12 and 13

D. 6, 8 and 10

Step-by-step explanation:

To see if three side lengths would give you a right triangle, you have to use the Pythagoras Theorem which is a² + b² = c², where c is the hypotenuse (longest side) and a and b are adjacent to the right angle.

A. 3² + 7² ≠ 10²

9 + 49 ≠ 100

58 ≠ 100

B. 4² + 9² ≠ 10²

16 + 81 ≠ 100

97 ≠ 100

C. 5² + 12² = 13²

25 + 144 = 169

169 = 169

D. 6² + 8² = 10²

36 + 64 = 100

100 = 100

Answer:

.25

Step-by-step explanation:

37.50/5=7.5

58/8=7.25

7.5-7.25=.25

Answer:

260

Step-by-step explanation:

So first you need to multiply 5 and 37. and the is 5×37 equals 185. So now your gonna multiply 8 by 58 and that is 464. So now that you have those two numbers ( 185, 464 ) your gonna add how ever much you need to get 464. So the closest to get to 464 is gonna be 260 I'm pretty sure.

Answer:

r<2

r greater than or equal to 7

Step-by-step explanation:

The solution for r in the two of the given inequalities is r<2 and r ≥ 7, respectively.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed. It is mostly denoted by the symbol <, >, ≤, and ≥.

The given inequalities can be solved as shown below.

1.)

2r + 3 < 7

Subtract 3 from both sides of the inequality,

2r + 3 - 3 < 7 - 3

2r < 4

Divide both the sides of the inequality by 2,

2r/2 < 4/2

r < 2

2.)

-r + 9 ≤ 2​

Subtract 9 from both sides of the inequality,

-r + 9 - 9 ≤ 2 - 9

-r ≤ - 7

Multiply from both sides of the inequality by -1,

(-r × -1) ≤ (-7 × -1)

r ≥ 7

Hence, the solution for r in the two of the given inequalities is r<2 and r ≥ 7, respectively.

Step-by-step explanation:

Answer:

Absolute value equation is:

|L - 72| ≤ 0.05

Solution is 71.05 ≤ L ≤ 72.5

Step-by-step explanation:

We are told that the length (l) of the boards that the company received varies from a maximum length of 0.05 inches longer than 6 feet to a minimum length of 0.05 inches shorter than 6 feet.

From conversions, 1 ft gives 12 inches. Thus, converting the 6 ft to inches gives us; 6 × 12 = 72 inches

This means that minimum value of L is 72 - 0.05 and maximum is 72 + 0.05.

Thus,the absolute value equation is;

|L - 72| ≤ 0.05

Solving this gives;

L - 72 ≤ 0.05 and -(L - 72) ≤ 0.05

This gives;

L ≤ 72 + 0.05 and -L + 72 ≤ 0.05

L ≤ 72.05 and 72 - 0.5 ≤ L

L ≤ 72.05 and 71.05 ≤ L
