Consider the rectangular prism below.
Which equation can be used to find the surface area, SA, of the rectangular prism?
Answer:
Option D
Step-by-step explanation:
Formula for the surface area of rectangular prism = 2(lb + bh + hl)
Here, l = Length of the prism
b = Width
h = Height
If l = 25 cm, b = 12 cm and h = 20 cm
Surface area of the rectangular prism = 2(25×12 + 12×20 + 20×25) cm²
Therefore, Option D will be the correct option.

A large bowl holds 5 2/3 cups of punch. Some more punch is added to the bowl to make a total of 10 cups of punch. Let represent the number of cups of punch that are added to the bowl. Write and solve an equation to find the number of cups of punch that are added to the bowl.
Answer:
4 1/3 cups
Step-by-step explanation:
All you have to do for this one is subtract 5 2/3 from 10, which is 4 1/3. Your equation could be 10-5 2/3=x.

1. Write the exponential function f(x) = -4^(x-2) in the form f(x) = ab^x
Answer:
[tex]\displaystyle f(x)=-\frac{1}{16}(4^x)[/tex]
Step-by-step explanation:
We have the function:
[tex]f(x)=-4^{x-2}[/tex]
And we want to convert this to the exponential form:
[tex]f(x)=ab^x[/tex]
First, using the power of a product property, we can rewrite our function as:
[tex]f(x)=-(4^x\cdot4^{-2})[/tex]
By evaluating the second term, we acquire:
[tex]\displaystyle f(x)=-\big(4^x\cdot \frac{1}{4}^2}\big)=-\big(4^x\cdot \frac{1}{16}\big)[/tex]
So, by rearranging, we acquire:
[tex]\displaystyle f(x)=-\frac{1}{16}(4^x)[/tex]
As desired.

What is the area of the triangle in the diagram?
Answer:
A is the correct answer
Step-by-step explanation:
We need to figure out the base and the height. We can do that using pythagorean's theorem.
The others either misused the pythagorean theorem or got the 1/2*base*height formula wrong, so A is the answer.

Since this is a 45°-45°-90° triangle, the side opposite the 90° angle is √2× the other two angles. The other two angles are congruent since their opposite angles are both 45°.
Hope this helped! :p
Step-by-step explanation:
2[tex]\sqrt{2}[/tex] is the hypotenuse
The other 2 sides are equal to b since this is a 45-45-90 triangle meaning that it's isosceles
[tex]2b^{2}[/tex] = ([tex]2\sqrt{2}[/tex][tex])^{2}[/tex]
[tex]2b^{2}[/tex] = ([tex]\sqrt{8})^{2}[/tex]
[tex]2b^{2}[/tex] = 8
[tex]b^{2}[/tex] = 4
b= 2
Hope this helps!!!

Simplify this expression: -2x + 3 – (5 – 6x). Can someone pls explain how to do this dont just give the awnser
Answer:
-2x + 3 – (5 – 6x) = 4x - 2
Step-by-step explanation:
The given expression is :
-2x + 3 – (5 – 6x)
We need to simplify the above expression. First opening the brackets.
-2x + 3 – (5 – 6x) = -2x + 3 – 5 + 6x
Taking like terms together,
= -2x+6x + 3 -5
= 4x - 2
So, the simplified expression is 4x - 2.

the angles of triangle abc are in the ratio of 8:3:4. what is the measure of all the angles?
Answer:
48:18:24 or ∠A = 48, ∠B = 18, ∠C = 24
Step-by-step explanation:
Since The angles of a triangle add up to 90, then 8 + 3 + 4 should equal to 90 if multiplied by x.
Example:
x(8 + 3 + 4) = 90
x(15) = 90
15/15x = 90/15
x = 6
If x is equal to 6, then 6 times 8, 6 times 3, and 6 times 4, should equal their respective angles and add up to 90.
Example:
8 * 6 = 48
3 * 6 = 18
4 * 6 = 24
48 + 24 + 18 = 90
This means the angles are
48:18:24 or ∠A = 48, ∠B = 18, ∠C = 24

Answer:
The simplified expression of [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] is 7² ⇒ C
Step-by-step explanation:
Let us revise some rules of exponent
[tex]a^{m}[/tex] × [tex]a^{n}[/tex] = [tex]a^{m+n}[/tex][tex]\frac{a^{m}}{a^{n}}[/tex] = [tex]a^{m-n}[/tex]Let us solve the question
∵ The expression is [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex]
→ By using the first rule above add the exponents of 7
∴ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = [tex]\frac{7^{4+6}}{7^{8}}[/tex]
∴ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = [tex]\frac{7^{10}}{7^{8}}[/tex]
→ By using the second rule above, subtract the exponents of 7
∵ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = [tex]7^{10-8}[/tex]
∴ [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] = 7²
∴ The simplified expression of [tex]\frac{7^{4}.7^{6}}{7^{8}}[/tex] is 7²
the answer is 7 power 2
