The radius of the moon is approximately 1,350,000 m. What is the radius in kilometers? (1 km=1000m)

Answers

Answer:

I believe it is 1,350 but i am not completely sure

Step-by-step explanation:

The radius of the moon in Kilometers is 1350 km.

What is unit conversion?

Multiplication or division by a numerical factor, selection of the correct number of significant figures, and unit conversion are all steps in a multi-step procedure.

Unit conversion is a multi-step procedure that involves adding, subtracting, multiplying, or dividing by a conversion factor. Additionally, rounding and choosing the appropriate number of significant digits may be necessary during the process. To measure various parameters, various units of conversion are utilized.

Given that the radius of the moon is approximately 1,350,000 m. The radius in kilometers will be calculated as,

1 km = 1000m

1 m = 1 / 1000 km

1350000 meters = 1350000 / 1000 km

1350000 meters = 1350 km

Brooklyn had 4.52 inches of rain in April. In May it rained 5.23 inches and 3.41 inches of rain in June. How much rain did the city have during this three-month period?

Answers

Answer:

[tex]Total = 13.16\ in[/tex]

Step-by-step explanation:

Given

[tex]April = 4.52\ in[/tex]

[tex]May = 5.23\ in[/tex]

[tex]June = 3.41\ in[/tex]

Required

Determine how much rain the city had

To do this, we simply sum the rainfall in the three months

[tex]Total = April + May + June[/tex]

[tex]Total = 4.52\ in + 5.23\ in + 3.41\ in[/tex]

[tex]Total = 13.16\ in[/tex]

Hence:

13.16 inches of rain fell

Patrick wants to use a gift certificate to buy some songs and videos
from an online media store.
• Songs (s) cost $1 each.
• Videos (v) cost $2.50 each.
• Patrick has a gift certificate for $25 for the store.
Which inequality represents the number of songs and videos Patrick
can buy using only his gift certificate?

Answers

Answer:

i think songs it might be correct but im not sure

The inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is s + 2.50v ≤ 25

What is inequality?

It is defined as the expression in mathematics in which both sides are not equal they have mathematical signs either less than or greater than, known as inequality.

Let's suppose the number of songs is 's' and number of videos is 'v'

Total cost for songs = $s

Total cost for videos = $2.50v

Patrick has a gift certificate for $25

Then the inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is:

s + 2.50v ≤ 25

Thus, the inequality that represents the number of songs and videos Patrick can buy using only his gift certificate is s + 2.50v ≤ 25

x + 15y = 40 / x + 10y = 30 solve for x and y

Answers

Use elimination to find both values.
Subtract the second equation from the first equation
x + 15y = 40
- x + 10y = 30
————————
5y = 10
y = 2

Plug in the value for y into one of the equations. I’m going to put it in the second equation.
x + 10(2) = 30
x + 20 = 30
x = 10

x = 10
y = 2

Find the volume of a pyramid with a square base, where the side length of the base is 4.8\text{ cm}4.8 cm and the height of the pyramid is 4.6\text{ cm}4.6 cm

Answers

Answer: 35.328 cubic inches.

Step-by-step explanation:

Volume of square pyramid = [tex]\dfrac{a^2}{3}h[/tex] , where a = length of base , h = height

Given: For a square pyramid

a= 4.8 cm and h = 4.6

Then, Volume = [tex]\dfrac{4.8^2}{3}\times4.6[/tex]

[tex]=\dfrac{23.04}{3}\times4.6\\\\=35.328\text{ cubic cm}[/tex]

Hence, the volume of a pyramid with a square base = 35.328 cubic inches.
