Answer:
[tex]V=7238.22\ \text{inches}^3[/tex]
Step-by-step explanation:
The diameter of a sphere, d = 24 inches
Radius, r = 12 inches
We need to find the volume of sculpture which is in the shape of sphere. The formula for the volume of a sphere is given by :
[tex]V=\dfrac{4}{3}\pi r^3\\\\V=\dfrac{4}{3}\pi \times (12)^3\\\\V=7238.22\ \text{inches}^3[/tex]
So, the volume of the sculpture is [tex]7238.22\ \text{inches}^3[/tex].
Entry tickets for a firework display were charged at £10
for children and £25 for adults. 800 people attended
the event and the ratio of adults to children was 7:9.
a.
Work out the total revenue from ticket sales
b.
60% of the tickets cost was given to charity.
How much was given to charity?
Answer:
Total revenue = $13,250
Amount given for charity = $7,950
Step-by-step explanation:
Children = $10
Adults = $25
Total people = 800
ratio of adults to children was 7:9.
Total ratio = 7 + 9 = 16
Adults = 7/16 × 800
= 0.4375 × 800
= 350
Adults = 350
Children = 9/16 × 800
= 0.5625 × 800
= 450
Children = 450
Total revenue = ($10 × 450) + ($25 × 350)
= $4,500 + $8,750
= $13,250
Total revenue = $13,250
60% of the tickets cost was given to charity.
Amount given for charity = 69% of $13,250
= 0.60 × $13,250
= $7,950
Amount given for charity = $7,950

Answer:
6.28 + 24 + 3 + 2 = 35.28 sq. units
Step-by-step explanation:
The screenshot is how I split it. (A semicircle with a radius of 2, a trapezoid (base a: 5, base b: 7, height 4), and two triangles (b1: 3, h1: 2; b2: 4, h2: 1)
To find the area of a semicircle, use the formula πr²/2. I'll use 3.14 for pi.
3.14(2²)/2
Square 2 to get 4.
3.14(4)/2
Multiply 3.14 by 4 to get 12.56.
12.56/2
Divide 12.56 by 2 to get 6.28
The semicircle is 6.28 units².
To find the area of a trapezoid, use the formula (a+b)h/2.
(5 + 7) * 4/2
Add 5 and 7 to get 12.
(12 * 4)/2
Multiply 12 by 4 to get 48.
48/2
Divide 48 by 2 to get 24.
The trapezoid is 24 units².
For the triangles, simply use this: bh/2
3 * 2 / 2
The 2's cancel out, so you're simply left with the first triangle being 3 units².
4 * 1 / 2
This really just becomes 4/2 as 4 * 1 is just 4.
4/2
Divide 4 by 2 to get 2.
The second triangle is 2 units².
Now that we know the areas of the four figures, add them together.
6.28 + 24 + 3 + 2
6.28 + 27 + 2
6.28 + 29
The area of the figure is 35.28 units².

Carlos is a member of a gym. He pays a monthly fee plus a per- visit fee. The equation y = 3x + 10 represents the monthly amount Carlos pays for x visits.
if Carlos pays $85 in the last month how many times did he visit the gym?
Answer:
25 times
Step-by-step explanation:
To find how many times he visited, plug in 85 as y and solve for x:
y = 3x + 10
85 = 3x + 10
75 = 3x
25 = x
So, Carlos visited the gym 25 times
8x2 - 6x + 3 – 2x – 10x?
Answer:
8[tex]x^{2}[/tex] + 3 + -6x
Step-by-step explanation:
First we need to find the like terms so that we could add them. In this case the like terms are,
1. 6x , -2x , -10x
So, these are the only terms that we can add in this expression.
Hence,
=> 8[tex]x^{2}[/tex] + 3 + (6x - 2x - 10x)
=> 8[tex]x^{2}[/tex] + 3 + -6x
And this is as simple as this expression can go until we find the value of "x" which is not yet told.

A town has a population of 18000 and grows at 2% every year. To the nearest tenth of a year, how long will it be until the population will reach 26700?
^^
Answer:
19.9
Step-by-step explanation:
we can write the following equation
18000(1.02)^n
where n is the number of years
so we have
26700=18000(1.02)^n
solve for n
1.483=1.02^n
use logs to solve for n
n=19.9
what is the value of c?
Answer:
The value of C is 3
Step-by-step explanation:
all of the angles of a triangle add up to 180°. first you would add 92 and 46 and get 138. You then subtract 180 and 138 and get 42. then you divide 42 by 14 and get 3. then substitute 3 back into the equation and you get 180.
