Volume of a Triangular Prism
V = 1/2BHLSolving
V = 1/2 x 7 x 8 x 10V = 7 x 10 x 4V = 280 m³Answer:
280
Step-by-step explanation:
So first lets establish the formula for a Triangular Prism :
1/2 * b * h * l
now lets use the mesurements given to substitute into the formula :
1/2 * 7 * 8 * 10
now lets solve it by first multiplying all the whole numbers together!
7 * 8 = 56
56 * 10 = 560
Finally lets multiply 560 by 1/2 or in other words, divide 560 by 2 :
560/2 = 280

In order to qualify for a role in a play, an actor must be taller than 64 inches but shorter than 68 inches. The inequality 64 < x < 68, where x represents height, can be used to represent the height range. Which is another way of writing the inequality?
x > 64 and x < 68
x > 64 or x < 68
x < 64 and x < 68
x < 64 or x < 68
Answer: x > 64 and x < 68 is another way of rewriting inequality.
Step-by-step explanation:
To qualify for a role in a play, an actor must be taller than 64 inches but shorter than 68 inches.
⇒The inequality 64 < x < 68, where x represents height,gives the range of height.
⇒In other words range of height can be x > 64 and x < 68 , such that both conditions are applied to single actor.

A builder wants to install a triangular window with the angles shown in the illustration. What angles will he have to cut to make the window fit? (Hint: The sum of the angles in a triangle equals 180°.)
x° =
°
(x + 30)° =
°
Answer:
X=40°
Step-by-step explanation:
40+30=70
40+30=70
70+70=140
140+40=180
The angles will builder has to cut to make the window fit is 40°, 70° and 70°.
Given that, the measures of the three angles of a triangle are x°, (x+30)° and (x+30)°.
What is the angle sum property of a triangle?The sum of all internal angles of a triangle is always equal to 180°. This is called the angle sum property of a triangle.
Now, x°+(x+30)°+(x+30)°= 180°
⇒3x+60°=180°
⇒3x=180°-60°
⇒3x=120°
⇒x=40°
So, x°=40°, (x+30)°= 70°
Therefore, the angles will builder has to cut to make the window fit is 40°, 70° and 70°.

Which of the Question A & B?
Answer:
A) 50 households are randomly selected from the town; 14 own a dog
B) 98
Step-by-step explanation:
A) The first choice is the most logical because it doesn’t factor in the accommodations that the other two do.
B) There are 14 households that own dogs per 50 houses, so multiply by 7 to find how many dogs are in the whole town:
50 x 7 = 350 houses
14 x 7 = 98 households

A good credit score is used for more than just getting a credit card or a loan. Credit scores demonstrate your history of paying your debts to entities that loan you money. Due to extending themselves beyond their means, many people are not able to pay their debts
Sophie has $40 in an account. The interest rate is 5% compounded annually. To the nearest cent, how much interest will she earn in 3 years? $
Answer:
$ 6.31
Step-by-step explanation:
The TOTAL amount in the account in 3 years will be
40 ( 1+.05)^3 = 46.31
subtract the orignal 40 deposit to get the interest =6.31
[tex]~~~~~~ \textit{Compound Interest Earned Amount} \\\\ A=P\left(1+\frac{r}{n}\right)^{nt} \quad \begin{cases} A=\textit{accumulated amount}\\ P=\textit{original amount deposited}\dotfill &\$40\\ r=rate\to 5\%\to \frac{5}{100}\dotfill &0.05\\ n= \begin{array}{llll} \textit{times it compounds per year}\\ \textit{annually, thus once} \end{array}\dotfill &1\\ t=years\dotfill &3 \end{cases}[/tex]

Frank needs to pay R60 000,00 towards his son’s university fees in three years’ time. If he has R46 150,30 now, at what interest rate per year compounded monthly, must he invest his money?
Using compound interest, it is found that he must invest his money at a rate of 8.78% a year.
What is compound interest?The amount of money earned, in compound interest, after t years, is given by:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
In which:
A(t) is the amount of money after t years. P is the principal(the initial sum of money). r is the interest rate(as a decimal value). n is the number of times that interest is compounded per year.In this problem, the parameters are as follows:
t = 3, A(t) = 60000, P = 46150.3, n = 12.
Hence:
[tex]A(t) = P\left(1 + \frac{r}{n}\right)^{nt}[/tex]
[tex]60000 = 46150.3\left(1 + \frac{r}{12}\right)^{12 \times 3}[/tex]
[tex]\left(1 + \frac{r}{12}\right)^{36} = 1.3[/tex]
[tex]\sqrt[36]{\left(1 + \frac{r}{12}\right)^{36}} = \sqrt[36]{1.3}[/tex]
[tex]1 + \frac{r}{12} = (1.3)^{\frac{1}{36}}[/tex]
[tex]1 + \frac{r}{12} = 1.00731451758[/tex]
[tex]\frac{r}{12} = 0.00731451758[/tex]
r = 12 x 0.00731451758
r = 0.0878.
He must invest his money at a rate of 8.78% a year.

Answer:
4) 97%
6) 13%
Step-by-step explanation:
4) We are given that 3% for 250 million are diesel.
100% - 3% = 97% NON DIESEL cars
97% of 250 million is 242.45 million.
______________________________
6) We know that 17% (buses) and 70% (cars) are part of that total.
We also know that the total needs to be 100%
So, we simply do this:
100 - (17+70) = 13 (%)
So, 13% of the survey participants had bikes
