n=
x=

Ill mark brainliest if yall help me and ill make it 20 points

Answers

Answer 1
1) 15 = 5(x + 2)
15 = 5x + 10
15 - 10 = 5x + 10 - 10
5 = 5x
5/5 = 5x/5
1 = x

2) 5n + 34 = -21(1-7n)
5n + 34 = -21 + 147n
5n + 34 = -21 + 147n
5n - 147n + 34 = -21 + 147n - 147n
-142n + 34 = -21
-142n + 34 - 34 = -21 - 34
-142n = -55
-142n/-142 = -55/-142
n = 55/142

Answer:

Step-by-step explanation:

The United States Postal Service delivers about 2^8⋅5^2 pieces of mail each second. There are 2^8⋅3^4⋅5^2 seconds in 6 days. How many pieces of mail does the United States Postal Service deliver in 6 days? Write your answer as an expression involving three powers.

Answers

Answer:

The total number of pieces delivered in 6 days is the number delivered each second (28.52) times the number of seconds in 6 days (28 34.52). This gives:

(28.52) (28 3¹.52) 28 + 8.31.52+2 = 216.31.54

find the area of each shaded sector. Round to the nearest hundredths place. Use 3.14 for pi​

Answers

Answer:

8.48cm²

Step-by-step explanation:

area of a sector = [tex]\frac{0\pi r^2\\\\}{360}[/tex]

where 0 = angle measure of sector

and r = radius

we are given the angle measure ( 23° ) and the radius ( 6.5 cm )

so all we have to do is plug in the values into the formula

(Note that the question asks us to use 3.14 for pi)

[tex]A=\frac{23*3.14* 6.5^2\\\\}{360}\\6.5^2 = 45.25\\23*3.14 =72.22\\72.22*45.25 = 3051.295\\\frac{3051.295}{360} =8.47581944[/tex]

so the area of the sector = 8.47581944 cm^2

finally we want to round to the nearest hundredth and we get that the answer is 8.48cm²

Step-by-step explanation:

Since both of the acute angles have around or similar degrees, they will be the same. But even without that information we can see that each of the angles look the same. We already know that there are 360° in a circle, making 180° in a semi-circle. We can add 60+60 which will give us 120°. 360-120=240, which dividing that by 2 will give us 120, and if we were figuring out the other 2 would be 120° each.

Justin drinks 1 litter of water.He drank 2,000 litters at his game.How many during his game and his practice?Explain.

Answers

The question is incomplete. The complete question is :

Justin drinks 1 litter of water during the soccer practice. He drank 2,000 milliliters of water at his game. How many liters of water did he drink during his game and his practice? Explain.

Solution :

It is given that :

During practice, Justine drank = 1 liter of water

During game, Justine drank = 2000 milliliters of water

We know that,

1 liter = 1000 mL

Therefore, during the game, Justine drank :

1000 mL = 1 liter

∴ 2000 mL = 2 liter

So Justine drank 2 liters of water during his soccer game and 1 liter of water during his practice.

Rebecca needs a box with a rectangular base of 36 cm2 and a volume of 180 cm3. What would be the height of this box? O A. 45 cm B. 30 cm C. 20 cm D. 15 cm E. 5 cm​

Answers

Answer:

Volume of box V = 180 cm^3

Base area of box A = 36 cm^2

Height = h

Volume = base area × height

height = volume/base area

h = V/A

Substituting the values;

h = (180cm^3)/(36cm^2)

Height h = 5 cm
