Answer:
64 ft²
Step-by-step explanation:
A prism is a three dimensional shape with two identical shapes facing each other known as bases. A right prism is a three dimensional solid with a polygon as its base and vertical sides which are perpendicular to the base.
Given that the first sandbox is a right prism a square base, hence this is a square prism (that is a cube).
Since the side length of the square base is 8 ft, hence the area of the base of the first sandbox is:
Area of the base = length * length = 8 ft * 8 ft = 64 ft²

A triangle has side lengths of 9 centimeters and 15 centimeters. The third side has a length of x centimeters. complete the inequality to show all the possible values of x.
Answer:
67.5
Step-by-step explanation:
area of a triangle (1/2 l×b)
1/2 ×9×15× x=135x
divide any side by 2
x=4.5×15=67.5
x=67.5
The value of x is 67.5.
We have given that,
A triangle has side lengths of 9 centimeters and 15 centimeters.
The third side has a length of x centimeters
What is the area of a triangle?The area of a triangle is (1/2 l×b)
l is length and b is a breadth.
Therefore we use the given value in the formula so
1/2 ×9×15× x=135x
divide any side by 2
x=4.5×15=67.5
x=67.5.
Therefore the third side of the triangle is 67.5.
So the inequality is
67.5≤15≤9.

Maha got a phone call while she was watching a movie. After she hung up, she rewound 15 minutes of the movie tape. Which point on the number line below represents −15? AlternativeText A. Z B. Y C. X D. W
Answer:
See Explanation
Step-by-step explanation:
The question is incomplete, as the number line is not given. The general explanation is as follows;
First, record the time she hung up (say, time = x)
To rewind 15 minutes back means, x - 15
So, point on the number line will be x - 15
Take for instance
[tex]x = 45[/tex]
The point on the number line will be:
[tex]x - 15 = 45 - 15[/tex]
[tex]x - 15 = 30[/tex]

35% of flowers sold on a day were roses. If 42 roses were sold, how many total flowers were sold?
Hence, 120 flowers were sold in total on that day as the Roses made up 35% of the total number of flowers.
what is unitary method ?In mathematics, the unitary approach entails determining the value of a single unit and then using that value to determine the value of a certain number of units. It is frequently applied to issues concerning rates and proportions as well as issues relating to ratios and proportions. The unitary method, for instance, would result in a cost of $5 for 5 apples if the price of 1 apple is $2. To calculate the overall cost using the unitary method, we would multiply the $2 worth of one apple by the quantity we wish to purchase. Therefore $5 would be spent on 5 apples, or $2 each.
given
Assume that "x" represents the total quantity of flowers sold on that particular day.
Roses made up 35% of the total number of flowers, which means that:
0.35x = 42
By dividing both sides by 0.35, we can determine the value of "x":
x = 120
Hence, 120 flowers were sold in total on that day as the Roses made up 35% of the total number of flowers.

What is the sum of the first eight terms in this series?
2 + 10 + 50 + 250
A.
97,656
B.
156,250
C.
195,312
D.
317
Answer: c
Step-by-step explanation: because of the 2 in the first one there will be a 2 in the answer
The sum of the first eight terms in this series is 97,750.
We have,
We notice that each term in the series is obtained by multiplying the previous term by 5.
Therefore, this is a geometric series with a common ratio of 5.
We can use the formula for the sum of the first n terms of a geometric series:
[tex]S_n = a(1 - r^n)/(1 - r)[/tex]
where a is the first term, r is the common ratio, and n is the number of terms.
In this case,
a = 2, r = 5, and n = 4 (since we have four terms).
Substituting these values into the formula gives:
[tex]S_4 = 2(1 - 5^4)/(1 - 5)[/tex]
= 2 (-624)/(-4)
= 156
The sum of the first four terms is 156.
To find the sum of the first eight terms, we need to find the sum of the first four terms and then multiply by the common ratio raised to the power of 4:
[tex]S_8 = S_4 \times 5^4[/tex]
= 156 x 625
= 97,500
Adding the last term (250) to this sum gives:
= [tex]S_8[/tex] + 250
= 97,500 + 250
= 97,750
Therefore,
The sum of the first eight terms in this series is 97,750.

Sven deposited R3500 into a savings account where interest is compounded annually at 11.2% at the end of two years he withdrew R1800.
calculate the amount of money left in the account after two years
Answer:
Amount left= 4,327.9 - 1,800
Step-by-step explanation:
Giving the following information:
Initial deposit (PV)= $3,500
Interest rate (i)= 11.2%
Number of periods (n)= 2 years
Withdrawal= $1,800
First, we need to calculate the future value of the investment at the end of 2 years:
FV= PV*(1 + i)^n
FV= 3,500*(1.112^2)
FV= $4,327.9
Now, after the withdrawal:
Amount left= 4,327.9 - 1,800
