The surface area of the moon is 37,932,330km squared. Calculate the side length of a square with the same area.

2 answers:

8 0

Area of a square = length²
length² = 37 932 330
length = √37 932 330
= 6160 km (to three signifcant figures)

The side length of a square with the same area would then be 6160 km.

First, you need to know that formula for the area of a square with the information given - length ^2
Since you know that the area is length^2then you would plug in the information given for the length which would be 37,932,330 then you take the square root of that because the opposite of ^2 would be the square root of the number. You would then get 6160km which is equal to three other figures but is also going to be your answer. 6160Km

Christina collected information about the ages of the players on her softball team. The ages were 10, 12, 14, 13, 12, 11, 13, 12

BARSIC [14]

We are told that Christina collected information about the ages of the players on her softball team. The ages were 10, 12, 14, 13, 12, 11, 13, 12, 11, 12, 12, and 13. Christina wants to describe the players’ ages in an article for the school newspaper.

Since we know that range of a data is difference between the highest and lowest values of a data set. Range of our data set will be 4 (14-10). A group of different ages could have same range as Christina's data set. So range will be not a good option.

A measure of central tendencies will be better option to represent information about ages of softball team players. Mean will give the average age of softball players.

$\text{Mean age of players}=\frac{10+11+11+12+12+12+12+12+13+13+13+14}{12}$

$\text{Mean age of players}=\frac{145}{12}=12.0833$

Let us find median of data.

10,11,11,12,12,12,12,12,13,13,13,14

$\text{Median age of softball players}=\frac{12+12}{2}$

$\text{Median age of softball players}=\frac{24}{2}=12$

We can see that average of our data is 12 years.

Therefore, a measure of central tendency will be better choice to describe ages of softball players.

Which value for x makes the sentence true? 2.45 + x = 3.64

Scrat [10]

Answer:

1.19

Step-by-step explanation:

You're trying to figure out what x is here.

So you'll want to isolate the x. That means, get it alone.

Since both sides are equivalent, when you subtract 2.45 from the x side, you also subtract it from the other side too.

x = 3.64 - 2.45

x = 1.19

Find the total surface area of this triangular prism. 17 cm 8 cm 2 cm 15 cm

kumpel [21]

Answer:

200cm²

Step-by-step explanation:

Total surface area of the prism = bh + L(s1+s2+s3)

b is the base of the triangle = 15cm

h is the height of the triangle = 8cm

Perimeter of the triangular base = s1 + s2 + s3 = 8+17+15

Perimeter of the triangular base = 40cm

L is the lateral height = 2cm

Substitute the given values into the formula;

Total surface area of the prism = 15(8) + 2(40)

Total surface area of the prism = 120+80

Total surface area of the prism = 200cm²

Hence the total surface area of the prism is 200cm²

Step-by-step explanation:

If you can get 3 shirts for $24 then that means that each shirt was $8. With that being said, 8 multiplied by 7 equals 56 so you would pay $56 for 7 shirts.
