Answer: 6 & 1/2
This is a mixed number with 6 as the whole part and 1/2 as the fractional part.
Your teacher may want you to enter the answer without the ampersand symbol. If that's the case, then you would type in 6 1/2.
=============================================================
Work Shown:
1/4 = 0.25
3 & 1/4 = 3 + 1/4 = 3 + 0.25 = 3.25
1/2 = 0.5
He runs 3.25 miles in 0.5 of an hour
d = distance = 3.25 miles
t = time = 0.5 hour
r = unknown rate or speed in miles per hour (mph)
------------
distance = rate*time
d = r*t
3.25 = r*0.5
3.25 = 0.5r
0.5r = 3.25
r = 3.25/0.5 .......... divide both sides by 0.5
r = 6.5
r = 6 + 0.5
r = 6 + 1/2
r = 6 & 1/2
His rate is 6 & 1/2 mph

$50 on 1st year plus the $425 over 17 years
$475
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)
For these questions, give your answers to 1 decimal place.
a) Change 21 out of 71 to a percentage
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%

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].
I need help with this problemmm, someone help mee!!.
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°

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

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.

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

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

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
