Answers

Answer 1

Answer:

x = 5

Step-by-step explanation:

Sum of angles = 180, so

60 + 80 + 8x = 180

140 + 8x = 180

8x = 180 - 140 = 40

x = 40/8 = 5

Ms. Johnson bought an area rug for her den. The perimeter is 30 feet. The width of the rug is
2yards What is the area of Ms. Johnson's rug in square feet and square yards?
in both feet and yards.

Answers

I believe it should be 54 square feet and 18 square yards

Answer:

6 sq yards, 54 sq feet

Step-by-step explanation:

30/3 = 10, 10 - 4 = 6, 6/2 = 3, 3 * 2 = 6

30/3 since we are calculating yards(3 ft = 1 yard), 10 -4 since 2 sides have the width of 2 yards. 6/2 since there is two sides left.

Basically the same thing for sq feet.

You have already done half of it. Now substitute for x1 = 4 and y = 5
y - 5 = 6/7(x - 4)
Multiply everything by 7 to remove fractions
7y - 35 = 6(x - 4)
7y - 35 = 6x - 24
-6x + 7y = -24 + 35
-6x + 7y = 11

Some people prefer a positive number in front of x so multiply by -1
6x - 7y = -11

You can check the answer by testing it works for both of the original points
6x4 - 7x5 = 24 - 35 = -11 true
6x-3 - 7x-1 = -18 - -7 = -11 true

Malcom has $638.54 in his checking account. He must maintain a $500 balance to avoid a fee. He wrote a check for 159.50 today. Write an inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a fee.
(9th grade Algebra 1)

Answers

The inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a fee is 638.54 - 159.50 + x ≥ $500

The given parameters:

initial amount of money in Malcom's account = $638.54

a constant balance to be maintained to avoid a fee = $500

amount to be withdrawn today = $159.50

To find:

inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a fee

Let the LEAST amount = x

Here are basic things to note in order to form the equation:

The money going into the account must be addedThe amount to be withdrawn will be subtracted Finally, the total amount must be greater or equal to  $500

Considering the above explanation, the inequality becomes;

638.54 + x - 159.50 ≥ $500

Rearrange to match the given options;

638.54 - 159.50 + x ≥ $500

Thus, the inequality that would be used to solve for the LEAST amount of money he needed to deposit to avoid a fee is 638.54 - 159.50 + x ≥ $500

Convert 19.3 picometers per squared kiloseconds (pm/ks^2) into megameter per squared nanoseconds (Mn/ns^2).

Answers

Unit conversion involves the conversion of a metric unit to another unit of the same quantity.

[tex]19.3 pm/ks^2[/tex] to megameter per squared nanoseconds is [tex]19.3 \times 10^{-41} Mn/ns^2[/tex]

Let:

[tex]x = 19.3 pm/ks^2[/tex]

Multiply by [tex]10^{-17[/tex] to convert megameter per squared kiloseconds

[tex]x = 19.3 \times 10^{-17} Mn/ks^2[/tex]

Divide by [tex]10^{24[/tex] to convert to megameter per squared nanoseconds

[tex]x = \frac{19.3 \times 10^{-17}}{10^{24}} Mn/ns^2[/tex]

Apply law of indices:

[tex]x = 19.3 \times 10^{-17-24} Mn/ns^2[/tex]

[tex]x = 19.3 \times 10^{-41} Mn/ns^2[/tex]

Answer:

∠LMP = 77

∠NMP = 103

Step-by-step explanation:

to find the measure of ∠LMP and ∠NMP

we know that ∠LMN is a straight line so that will be 180 degrees

so you can say that

∠LMP + ∠NMP = 180

(-16x +13) + (-20x +23)  = 180

-16x +13 -20x + 23  = 180

-36x + 36 = 180

-36x = 180-36

-36x = 144

x = 144/-36

x = -4

∠LMP = (-16x +13)

          = ( -16 (-4) + 13)

         = ( 64 + 13)

         = 77

∠LMP = 77

∠NMP = (-20x +23)

          =  (-20 (-4) + 23)

          = 80 + 23

          = 103

∠NMP = 103
