Mia found the volume of a rectangular prism to be 840 mm3. As she was telling her father about it. she remembered that the base had a length of 10 mm and a width of 12 mm, but she could not remember the height maybe there is a way you can find it by going backwards . her father suggested. Can you help Mia find the height of her prism. Explain your solution.
Answers
Answer:
H = 7mm
Step-by-step explanation:
Height of Prism
So to calculate the height, multiply L · H · W. But since there is no height we will multiply what is given and then divide the volume by the product. For this case, the volume of the prism is 840 and its length is 10 and its width is 12. Multiply 10 and 12 then dividing 840 by 120. The height of the prism is 7.
Solve
Volume if the rectangular prism is given by the formula
V = L · H · W
Length, Height, Width of the prism
L = 10mm H = 12mm Volume = 840mm³
10 · 12 · h = 840
∴ 840 ÷ 120 = 7
H = 7mm

Peter is 8 years younger than Jonne. In 5 years time, Jonne will be twice as old as Peter. How old is Peter now?
Answers
Answer:
Age of Peter = 3 year
Step-by-step explanation:
Given:
Peter is 8 years younger than Jonne
Assume;
Age of Jonne = a
So,
Age of Peter = a - 8
After 5 years,
2[a - 8 + 5] = a + 5
2a - 6 = a + 5
a = 11
Age of Jonne = 11
Age of Peter = 11 - 8
Age of Peter = 3 year

A person invested $7,400 in an account growing at a rate allowing the money to
double every 6 years. How much money would be in the account after 4 years, to the
nearest dollar?
Answers
Using an exponential function, it is found that $11,747 will be in the account after 4 years.
What is an exponential function?An increasing exponential function is modeled by:
[tex]A(t) = A(0)(1 + r)^t[/tex]
In which:
A(0) is the initial value.r is the growth rate, as a decimal.In this problem, considering the initial investment of $7,400, and the fact that it doubles every 6 years, the equation is given by:
[tex]A(t) = 7400(2)^{\frac{t}{6}}[/tex]
Hence the amount in 4 years is given by:
[tex]A(4) = 7400(2)^{\frac{4}{6}} = 11747[/tex]

Determine if 0.69789978997899789 is rational or irrational
Answers
The given decimal 0.69789978997899789 is irrational since 7899 is repeating.
What is an irrational number?Any real number that cannot be written as the quotient of two integers, p/q, where p and q are both integers, is referred to as an irrational number.
In another word, irrational numbers are those numbers that can not terminate.
For example, √2, and √3 are irrational numbers because they cannot be written as p/q where p and q both should be integers.
Given the decimal
0.69789978997899789
Now if we see then 7899 is repeating it means it will going to repeat and it ends so it is not apple to write in form of p/q so it will be an irrational number.
Hence "The given decimal 0.69789978997899789 is irrational since 7899 is repeating".

A. 1 Degrees
B. 10 Degrees
C. 100 Degrees
D. 180 Degrees
Answers
Answer:
180 degrees
Step-by-step explanation:
because 52 degrees + 104 degrees + 24 degrees = 180 degrees
Answer:
B. 10 Degrees.
Step-by-step explanation:
The degrees of the angles on a triangle must have a sum of 180 degrees.
100 + 70 = 170.
180 - 170 = 10.
This is how you know 10 degrees is what the third angle must be.
100 + 70 + 10 = 180.
So, B is your answer.

The Oates family went out to
dinner. The price of the meal was
$33.95. They left a 15% tip.
What was the total cost?
Answers
Answer:
$39.04
Step-by-step explanation:
1.Approach
To solve this problem, one must first find the amount of tip that was left, then add the value to the cost of the meal. The amount of tip given can be found by dividing the percent value of the tip by (100) and then multiplying the result by the price of the meal.
2.Find the amount of tip
To find the amount of tip that was left, divide the percent value of the tip by (100). This technique converts the percent into a decimal. After doing so, multiply the result by the cost of the meal.
Tip as a percent: 15%
Tip as a decimal: 0.15
Amount of tip left:
33.95 * 0.15 = 5.0925
Round the result
~5.09
3.Find the total bill
Disincluding the tax, one now has to add the tip to the cost of the meal to find the total amount paid.
(tip) + (price)
= (5.09) + (33.95)
= (39.04)
