how much bigger is the area of a pizza with a diameter of 18 inches than the area of a pizza with a diameter of 10 inches
Answer:
approximately 3.24 times greater
Step-by-step explanation:
The formula for the area of a circle of radius r is A = πr². Because we are given the diameter here (not the radius), we substitute d/2 for r in the above formula, obtaining:
A = π(d/2)²
Case 1: A = π [18 in / 2]² = π(9 in)² = 81π in²
Case 2: A = π[10 in/2]² = π[5 in]² = 25π in²
Dividing 81π in² by 25π in² gives us the desired result:
The area of the larger pizza is 81/25 times the area of the smaller one, or approximately 3.24 times greater.

What is the solution to h over negative 24 less-than-or-equal-to 18?
h greater-than-or-equal-to 432
h less-than-or-equal-to 432
h less-than-or-equal-to negative 432
h greater-than-or-equal-to negative 432
Answer:
the answer is the last one.
Step-by-step explanation:
First we multiply both sides of the inequality by -24 to isolate the variable.
Then, since we are multiplying with a negative number, the inequality sign flips.
All we do next is calculate.
Step by step we have
[tex] \frac{h}{ - 24} \leqslant 18 \\ - 24 \times \frac{h}{ - 24} \geqslant - 24 \times 18 \\ h \geqslant - 432[/tex]

50%
Step-by-step explanation:
If there are 4 parts to the spinner, 4 is the whole. Since there are 2 even numbers (2&4), the fraction would be [tex]\frac{2}{4}[/tex], which is simplified to [tex]\frac{1}{2}[/tex]. And because [tex]\frac{1}{2}[/tex] could also turn into [tex]\frac{50}{100}[/tex], the percentage is 50%.

Step-by-step explanation:
We need to find the value of angle D so that we can solve for X. To do that we need to find the value of angle A and that value will be the same value as D because these angles are the same.
To do that we have to add angles C and B together and that equals 118°. Then we have to realize that all the angles of a triangle add up to 180°. So then we have to subtract 118° from 180° and that equals 62°. So now we have the value of A.
If the value of angle A is 62° then that must be the value of angle D because these two angles are the same. So now that we have the value of angle D we need to solve for X. This equation is asking what times 2 equals the value of X. We know the value of X is 62°. So what times 2 equals 62°?
31×2=62°
Therefore the value of X is 31

Vicky reads at a constant rate. She can read 5 pages in 9 minutes. We want to know how many pages, p, Vicky can read after t given minutes.
Write a linear equation in two variable that represents the number of pages Vicky reads in any given time interval.
Answer:
p = (5t)/9
Step-by-step explanation:
9 mins ---------- 5 pages
1 min -------------5/9 page
t mins ------------5/9 x t pages
thus
p = (5t)/9
The linear equation in two variable that represents the number of pages (p) Vicky reads in any given time interval (t) will be;
⇒ p = 5t/9
What is linear expression?
A linear expression is an algebraic statement where each term is either a constant or a variable raised to the first power.
Given that;
She can read 5 pages in 9 minutes at a constant rate.
Now,
Since, She can read 5 pages in 9 minutes at a constant rate.
Hence, In 9 minutes = 5 pages
So, In 1 minutes = 5/9 pages
Hence, In t minutes, Number of pages = 5t/9
Thus, We can formulate;
The linear equation in two variable that represents the number of pages (p) Vicky reads in any given time interval (t) will be;
⇒ p = 5t/9

a floor plan is drawn using a scale of 3cm/15ft what length is represented by 1 centimeter ?
A ratio expresses the number of times one number contains another. The length represented by 1 centimeter in real is 5ft.
What is a Ratio?A ratio expresses the number of times one number contains another. For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six. Similarly, the lemon to orange ratio is 6:8, while the orange to total fruit ratio is 8:14.
Given that a floor plan is drawn using a scale of 3cm/15ft. Therefore, the 3 cm on the floor plan represents 15 ft in real. Thus, we can write the ratio as,
Ratio = Length on floor plan/Length in real = 3cm / 15 ft
Length on floor plan/Length in real = 3cm / 15ft
Now, the length represented by 1 centimeter in real can be written as,
Length on floor plan/Length in real = 3cm / 15ft
1 cm/Length in real = 3cm / 15ft
Length in real = (15ft × 1cm)/3cm
Length in real = 5 ft
Hence, the length represented by 1 centimeter in real is 5ft.

The volumes of two similar solids are 729m3 and 512 m3. The surface area of the solid is 324m2 What is the surface area of the smaller solid?
Step-by-step explanation:
Step 1: Make an equation
[tex]\frac{volume_1}{surface-area_1} = \frac{volume_2}{surface-area_2}[/tex]
[tex]\frac{729}{324} = \frac{512}{x}[/tex]
Step 2: Cross multiply
[tex]\frac{729}{324} = \frac{512}{x}[/tex]
[tex]729(x) = 324(512)[/tex]
[tex]729x = 165888[/tex]
Step 3: Divide both sides by 729
[tex]729x / 729 = 165888 / 729[/tex]
[tex]x = \frac{165888} {729}[/tex]
[tex]x = 227.555...[/tex]
Answer: [tex]x = \frac{165888} {729}[/tex] or in decimal form - [tex]x = 227.555...[/tex]
Answer:
256 m²
Step-by-step explanation:
(Ratio of sides)³ = Ratio of volumes
729/512 = (Ratio of sides)³
Ratio of sides = 9/8
(Ratio of sides)² = ratio of area
(9/8)² = (324/x)
x = 256

x(x + 2) = 24
x2 + 2x - 24 = 0
x2 + 2x - 48 = 0
x2 + (x + 2)2 = 100
Answer:
A, 0.5(x)(x+2)=24, D, x²+2x-48=0, and E, x²+(x+2)²=100
Step-by-step explanation:
A and D are correct because they simply involve the Area of a Triangle formula. A has the formula in the same format, but D has the 0.5 divided from by both sides.
E, on the other hand, uses the Pythagorean theorem to solve for both legs.

Answer:
15
Step-by-step explanation:
When two lines intersect the sum of the angles on one side of the line will be equal to 180. This means that you can add the two values and get 180.
Add the values you have and solve for x.
6x + 3 + 87 = 180
6x + 90 = 180
6x = 90
x = 15
Answer: x = 14
Step-by-step explanation: assuming that (6x + 3) degrees = 87 degrees
6x+3 = 87
6x = 84

what is the value of a when we rewrite (6/17)^9 x as a^x
The value of a when rewriting (6/17)^9 x as a^x is (6/17)^9.
Explanation:To find the value of a when we rewrite (6/17)^9 x as a^x, we are looking for a base a that can represent (6/17)^9 raised to the power x. To achieve this, we recognize that (6/17)^9 can be the value of the base a. Therefore, the expression (6/17)^9 x is the same as a^x, where a is equal to (6/17)^9.
