Which equation illustrates the identity property of multiplication? (a bi) × c = (ac bci) (a bi) × 0 = 0 (a bi) × (c di) = (c di) × (a bi) (a bi) × 1 = (a bi)
The equation that illustrates the identity property of multiplication is (a+bi) × 1 = (a+bi).
What is an equation?
An equation is formed when two equal expressions are equated together with the help of an equal sign '='.
The identity property of multiplication states that when a factor is multiplied by 1 the result is the factor itself. Therefore, the equation that illustrates the identity property of multiplication is (a+bi) × 1 = (a+bi).

The surface area of a rectangular-prism-shaped skyscraper is 1,115,000 m2. What is the surface area of a similar model that has a scale factor of 1/800? Round your answer to the nearest tenth.
The surface area of a similar rectangular-prism-shaped skyscraper that has a scale factor of 1/800 would be equal to 1.7 meter.
The surface area of a rectangular prism.Mathematically, the surface area of a rectangular-prism is given by this formula:
A = 2(wl + hl + hw)
Where:
A is the surface area.l is the length.w is the width.h is the height.Given the following data:
Surface area of rectangular prism = 1,115,000 m²
Scale factor = 1/800
The length, height and width of the similar model would be 1/800 the original rectangular-prism-shaped skyscraper.
Substituting the given parameters into the formula, we have;
Surface area = 1,115,000 × 1/800 × 1/800
Surface area = 1.7 meter.

The interpretation of the slope in the equation y = 1.25x + 9.5 is that 1.25 inches of candles are made per hour
How to interpret the slope?The linear model is given as:
y = 1.25x + 9.5
A linear model is represented as:
y = mx + b
Where;
m = slope
So, we have:
m = 1.25

Jackie went to the movie theater where he bought drinks and popcorn bags for his group of friends. Each drink was $4 and a bag of popcorn was $6. He spent a total of $108. He bought a total of 22 items combined. Write a system of equations that could be used to determine the number of drinks and popcorn bags that Jackie bought at the movie theatre. Define the variables used.
Answer:
x-intercept is 8, meaning if you get 8 candy bars, you can get 0 popcorn bags.
y-intercept is 6, meaning if you get 6 popcorn bags, you can get 0 candy bars. When Jackie had 0 candy bars, she had 6 (y-intercept) bags of popcorn and when Jackie had 0 bags of popcorn, she had 8 (x-intercept) bars of candy.
Step-by-step explanation:
The y-axis represents the amount of popcorn bags she has and the x-axis has the amount of candy bars. When the linear line intercepts with either axis, at least one axis is always at zero.
Lillian bought snacks for her team's practice. She bought a bag of apples for $2.36 and a 4-pack of juice bottles. The total cost before tax was $6.48. How much was each bottle of juice?
Answer:
$1.030 ($1.03 rounded.)
Step-by-step explanation:
First, we need to start of making an equation.
$2.36 + x = 6.48.
We will use x as the variable for the amount of each bottle of juice, because it is unknown.
Then, we must put the variable on one side of the equation. To do this, we must subtract $2.36 from $6.48; and $2.36 - $2.36.
$2.36 - $2.36 crosses out; 0. $6.48 - $2.36 = $4.12.We get the result that x = $4.12. However, only 1 pack is $4.12, and we must find the cost of 4 juice bottles. Therefor, we divide 4.12 by 4.
4.12 / 4 = 1.030. Now, to round the answer, this would be $1.03 per bottle.If Lillian bought a bag of apples for $2.36 and a 4-pack of juice bottles. The total cost before tax was $6.48 then each juice bottle costs $1.03.
Let's denote the cost of each juice bottle as "x".
Since Lillian bought a 4-pack of juice bottles, the total cost of the juice is 4x.
Given that the total cost before tax was $6.48, we can set up an equation:
Cost of apples + Cost of juice = Total cost
$2.36 + 4x = $6.48
Now, solve for "x":
4x = $6.48 - $2.36
4x = $4.12
x = $4.12 / 4
x = $1.03
Hence, Each bottle of juice costs $1.03.

What are prime numbers used for?
A prime number (or a prime) is a natural number greater than 1 that is not a product of two smaller natural numbers. A natural number greater than 1 that is not prime is called a composite number. For example, 5 is prime because the only ways of writing it as a product, 1 × 5 or 5 × 1, involve 5 itself. However, 4 is composite because it is a product (2 × 2) in which both numbers are smaller than 4. Primes are central in number theory because of the fundamental theorem of arithmetic: every natural number greater than 1 is either a prime itself or can be factorized as a product of primes that is unique up to their order.

The area of a right triangle can be found using the equation (a*b)/2.
The 2 legs of T1 are 8 in. and 6 in. (from 10 - 4)
Area of T1 = [tex]\frac{8 * 6}{2}[/tex] = 24 in.^2
The 2 legs of T2 are 8 in. and 4 in.
Area of T2 = [tex]\frac{8 * 4}{2}[/tex] = 16 in.^2

Factor out and show the step by step explanation of the answer for x^2+24x+5
Answer:
x =(24-√596)/2=12-√ 149 = -0.207
x =(24+√596)/2=12+√ 149 = 24.207
Step-by-step explanation:
Factoring x2-24x-5
The first term is, x2 its coefficient is 1 .
The middle term is, -24x its coefficient is -24 .
The last term, "the constant", is -5
Multiply the coefficient of the first term by the constant 1 • -5 = -5
Find two factors of -5 whose sum equals the coefficient of the middle term, which is -24 .
-5 + 1 = -4
-1 + 5 = 4
Two solutions were found :
x =(24-√596)/2=12-√ 149 = -0.207
x =(24+√596)/2=12+√ 149 = 24.207
The diameter of a circle is 18 in. Find its area in terms of
π
π.
Answer: 81 π.
Step-by-step explanation: To find the area of a circle, you need to multiply the circle's radius squared by pi. However, this problem is in terms of pi, so we're just going to find the radius squared. We're given the diameter, but we can simply cut it in half since the radius is half the diameter. The diameter for this circle is 18, so divide 18 by 2, and 9 is your radius. 9^2 is 81, so 81 π is your answer in terms of pi because when you find the radius squared, you put pi next to it.
