Answer:
The volume of this Prism is 30.
Step-by-step explanation:
Multiply the bases measurements together first. 3 x 10 = 30
Divide the base and height by 2. 30 / 2 = 15
Multiply the base area times the height. 15 x 2 = 30
Answer: 1.23×10¹⁶
Step-by-step explanation:
For this problem, we want to use order of operations to solve.
Parenthesis
Exponent
Multiply
Divide
Add
Subtract
Let's first solve the parenthesis.
[add denominator]
[cross multiply]
[divide]
[exponent]
1.23×10¹⁶
The ending result is way too large. Therefore, we use scientific notation and get 1.23×10¹⁶.
You would multiply 29.50 x 0.07 which would give you 2.065. The tax amount would be $2.07. The total after tax would be $31.57
Answer:
A
Step-by-step explanation:
Since the angle that is touching each other shows that it is equal, the lines also show equality. So the number of lines in one of them is the same length in the other.
Answer:
9 Model As.
Step-by-step explanation:
Let A represent Press A and let B represent Press B.
So, they own 14 total presses. This means that:

They can print 905 books per day, in other words, since A prints 70 per day and B prints 55 per day:

This is now a system of equations. Solve by substitution. From the first equation, subtract B from both sides:

Substitute this into the second equation: "

First, we can divide everything by 5 to simplify things:

Distribute the left:

Combine like terms:

Subtract 196 from both sides:

Divide both sides by -3

So, the company has 5 Model B presses.
Which means that the company has 14-5 or 9 Model A presses.
And we're done!
