No; the mean is the average amount of tips she makes, not the different amounts she makes each day.

If log10x=−3 , what is the value of x ?
IgorC [24]

log10x=−3

10 ^(log10x) = 10^(-3)

10x = 10^-3

x =10 ^ -3 / 10

x = 10^-4

x = .0001

x=1/ 10000

There were 287 music books and 134 science books in the store. After some books were sold there are 159 books left. How many boo
stiks02 [169]

Answer:

262 books sold

Step-by-step explanation:

This is a very vague word problem, but if it truly is just asking the amount of books sold (regardless of music or science), here's how to get the answer:

1. 287+134=421 - first you want to add together the two types of books to get the total amount of books in the store

2. 421-x=159 - create an equation and solve.

3. -x=-262 - follow order of operations and subtract 421 on both sides in order to isolate the variable

4. x=262 - divide each side by -1 to make the variable positive.

If you'd like an easier way, you can just:

1. 421-159=262 - it's easier, but my math teacher would count us wrong if we didn't do equations a specific way. Good luck!

Is the ans i got correct?<br>the total surface area is 33.8cm² <br>​
ElenaW [278]

Given:

A prism with height 5 cm and equilateral triangular base with side 2 cm.

To find:

The total surface area of the prism.

Solution:

Area of an equilateral triangle is:

A_1=\dfrac{\sqrt{3}}{4}a^2

Where, a is the side length.

Putting a=2, we get

A_1=\dfrac{\sqrt{3}}{4}(2)^2

A_1=\dfrac{\sqrt{3}}{4}(4)

A_1=\sqrt{3}

A_1\approx \sqrt{3}

The base and top of the prism are congruent so their area must be equal.

The lateral surface area of the prism is:

LA=Ph

Where, P is the perimeter of the base and h is the height of the prism.

The lateral surface area of the prism is:

A_2=(2+2+2)5

A_2=(6)5

A_2=30

Now, the total surface area is the sum of areas of bases and lateral surface area.

A=2A_1+A_2

A=2(1.73)+30

A=3.46+30

A=33.46

Therefore, the total surface area is 33.46 cm².
