Express 700 as a product of its prime factors in index form.
Write the prime factors in ascending order.
Answer:
700 = 2² × 5² × 7
Step-by-step explanation:
We need to find 700 as a product of its prime factors in index form.
Prime factors of 700 =2 x 2 x 5 x 5 x 7
= 2² × 5² × 7
So, 700 is equal to 2² × 5² × 7.
Hence, 700 is expressed as a product of its prime factors in index form.

Find the missing angles .
Answer:
f=60 , c=30
Step-by-step explanation:
there are 2f and 2c in the graph and f=2c
So
f+f+c+c=180
2c+2c+c+c=180
6c=180
c=180/6
c=30
f=2c
f=2×30
f=60

b) Change 46 out of 154 to a percentage
Answer:
a) 29.6%
b)29.9%
Step-by-step explanation:
Here, we want to change the values to percentage form
a) we have this as;
21/71 * 100% = 29.6%
b) we have thus as;
46/154 * 100% = 29.9%

Concrete is made by mixing screenings cement and sand in the ratio 3:1:15. How much sand would be needed to make 125 tons of concrete?
Answer:
= 98.7 tons
Step-by-step explanation:
ratio = 3:1:15
amount of sand needed = (15/19)*125 / 3 + 1 +15 =19
PLZZ HURRY The students at Southern Junior High School are divided into four homerooms. Benjamin just moved into the school district and will be randomly assigned to one homeroom.
Which methods can be used to simulate this situation? Select three options..
Flip a coin 4 times, once for each homeroom, with heads up representing being assigned to the homeroom represented by that flip.
Draw a marble from a bag containing 5 white marbles, 5 black marbles, 5 red marbles, and 5 green marbles, with each color representing a different homeroom.
Use a random number generator with 1, 2, and 12 representing the first homeroom, 7, 9, and 10 representing the second homeroom, 3, 8, and 11 representing the third homeroom, and 4, 5, and 6 representing the fourth homeroom.
Roll a number cube with 1 representing the first homeroom, 2 representing the second homeroom, 3 representing the third homeroom, and any other outcome representing the fourth homeroom.

2 + x -4 = 5
2 + x = 5 + 4
2 + x = 9
x = 9 - 2
x=7
Answer:
x=7
Step-by-step explanation:
2+ x - 4= 5| -2

What’s 5x + 5 factored?
Answer:
5(x+1)
Step-by-step explanation:
So factor is to make it simplified like x(y+c) {I made up random variable for an example but almost all factored problems look like this}
So first find the Greatest Common Factor or GCF for short
The GCF between 5x and 5 is 5
So you divide the whole thing by 5
5x+5/5
you’d get x+1
Now for the 5 just put it around X+1 but with parenthesis
5(x+1)

A farmer is building a new silo. The circular silo is 27 meters tall and has a radius of 14 meters. What is the area of the base of the silo? Round your answer to the nearest tenth. Use 3.14 for pi
Answer:
615.44m²
Step-by-step explanation:
The base of the silo is a circle
Rea of the base of the silo = πr²
r is the radius of the silo
Given
radius r = 14m
Area of the base of the silo = π(14)²
Area of the base of the silo = 3.14(196)
Area of the base of the silo = 615.44
Hence the area of the base of the silo is 615.44m²

1. find the mean amount
charged = $ ?
=======================================================
Work Shown:
To find the average price, we will add up the 9 values in column 2 to get
120+272+358+328+406+392+530+592+610 = 3,608
Then divide that total by 9 since there are 9 values we added up
We get the average to be (3,608)/9 = 400.888 which is approximate. This rounds to 400.89
Side note: It's a bit strange how your teacher mentions "charge in pounds" but then uses a dollar sign.
Step-by-step explanation:
To find the mean, you add all the numbers together then divide by the number of numbers.
Charge : 120+272+358+328+406+392+530+592+610=3608/9=400.888888 =400.89 dollars
The measure of an angle is 8 degrees less than three times the measure of another angle. If the two angles are supplementary (two angles whose sum is 180) what is the measure of the larger angle?
Answer:
The measure of the larger is [tex]133^{\circ}[/tex].
Step-by-step explanation:
Given:
The measure of an angle is [tex]8[/tex] degrees less than three times the measure of another angle.
The two angles are supplementary.
To find: The measure of the larger angle.
Solution:
Let the measure of the smaller angle be [tex]x^{\circ}[/tex].
Then the measure of the larger angle be [tex]3x^{\circ}-8^{\circ}[/tex].
The two angles are supplementary, so their sum is [tex]180^{\circ}[/tex].
So, [tex]x^{\circ}+3x^{\circ}-8^{\circ}=180^{\circ}[/tex]
[tex]\Rightarrow 4x^{\circ}-8^{\circ}=180^{\circ}[/tex]
[tex]\Rightarrow 4x^{\circ}=180^{\circ}+8^{\circ}[/tex]
[tex]\Rightarrow 4x^{\circ}=188^{\circ}[/tex]
[tex]\Rightarrow x^{\circ}=\frac{188^{\circ}}{4}[/tex]
[tex]\Rightarrow x^{\circ}=47^{\circ}[/tex]
So, the measure of the smaller angle is [tex]47^{\circ}[/tex].
And, the measure of the larger angle is [tex]3\times47^{\circ}-8^{\circ}=133^{\circ}[/tex].
Hence, the measure of the larger is [tex]133^{\circ}[/tex].
Mr. And Mrs. Donahue want to buy a home valued at $365,000. If they have 21.5% of this amount saved for a down payment, how much will their home loan be? a. $78,475 b. $286,525 c. $341,275 d. $357,153
Answer: b. $286,525
Step-by-step explanation:
The amount the have saved for a down payment is:
= 365,000 * 21.5%
= $78,475
They will have to get the rest by loan which is:

expand the expression -2.5(-3 + 4n + 8)
Answer:
2.5+7.5+-10n+-20
Step-by-step explanation:
Multiply everything on the inside by the number on the outside and put it together with addition signs.
-2.5(-3+4n+8)
-2.5*-3=7.5
-2.5(7.5+4n+8)
-2.5*4= -10
-2.5(7.5+-10n+8)
-2.5*8=-20
-2.5+7.5+-10n+-20
Answer: 7.5 + 200n
Step-by-step explanation:
(-2.5 • -3) + (-2.5 • 4n) + (-2.5 • 8)
7.5 + -10n + -20
7.5 + 200n

Answer:
∠A=30°
Step-by-step explanation:
let's call the angle at the bottom B and the one next to the 130 C
∠A=3x-6
∠C=180-130= 50°
vertical angles are equal∠B =8x+4
∠A+∠C+∠B=180°
find x:
3x-6+50+8x+4= 180°
11x+48=180°
11x= 132
x=12
find ∠A
∠A=3x-6= 3(12)-6 =30°
