Answer:
20√5 - 10√10
Step-by-step explanation:
6√20 + 8√5 - 5√45
first, 6√20 and 5√45 need to be simplified. 8√5 cannot be simplified any further:
6√20 = 6√4•5 = 6√2•2•5 = 6•2√5 = 12√5
5√45 = 5√8•5 = 5√2•2•2•5 = 5•2√2•5 = 10√10
now:
12√5 + 8√5 - 10√10
then, add the coefficients of 12√5 and 8√5
20√5 - 10√10
the left over numbers cannot be combined because they do not have a common radical, making 20√5 - 10√10 the final answer
One gallon is approximately 3.79 liters. Write a direct variation equation that relates 2 gallons to y liters.
370
Answer:
2 gallons x 3.79 = 7.58 liters
Step-by-step explanation:
1 gallon = 3.79 liters
so
2 gallons x 3.79 liters = 7.58 liters
2 x 3.79 = y liters

The length of a rectangle is three times its width, if the area of the rectangle is 108cm2, find its perimeter
Answer:
The perimeter of rectangle is 48 cm.
Step-by-step explanation:
First, you have to form an expression for the length and the width. Let x be the width :
width = x cm
length = 3 × x = 3x cm
Then, you have to apply area of rectangle formula, A = length × width to find the value of x.Let area equals to 108 :
A = length × width
108 = 3x × x
3x² = 108
x² = 108 ÷ 3
x² = 36
x = √36
x = 6 cm
Lastly, you have to find perimeter :
length = 3 × 6 = 18 cm
width = 6 cm
Perimeter = 2(length + width)
P = 2(18 + 6)
P = 2(24)
P = 48 cm
Answer:
48cm

Find the product.
120 ×(0.002). It is 6th grade work don’t worry about where it says college
Answer:
0.24
Step-by-step explanation:
120 x 0.002 = 0.24
The correct answer is 0.24.
To find the product of 120 ×(0.002).
The zeroes are multiplied by the power of 10 which is 1/10 in particular.
For example.
The product of a whole number and a decimal number less than 1 will be greater than the whole number multiplied into. For this theorem to be proven. Let us state the mathematical expression into numbers such that
1. N x 0.1 = N/0.1 < N
2. 1 x 0.5 = 0.5
3. 2 x 0.1 = 0.2
4. 100 x 0.55 = 55
120 ×(0.002) = 0.24.
Therefore, the 120 × 0.002 = 0.24

Each but is 21/100 meters long. Write the fraction as a decimal then calculate how long all eight books are all together
Answer:
1.68 Meters
Step-by-step explanation:
Hello I think I can help with this.
Well basically the way it is represented as a fraction is a portion of a whole like a percent :
For example : 21%
So basically we just need to turn this into a decimal and then add to find how long the books would be together.
How I would go about doing this is first looking at the 21/100 and remember that in decimals 1.00 is a whole just like the 100. So in this case the 100 in 21/100 would be 1.00.
So knowing this, we can take the 21 in 21/100 and say that 0.21/1.00 is equal to 21/100 because the 21 is representing how much of a meter the books are while 100 is the whole meter.
Now, we know we have eight books and each are .21 long. So we can do :
.21 x 8
=
1.68
While this is the answer we can write it in two ways. Either in fraction form like it started or in decimal form which I think is how they want you to write the answer.
For fraction :
168/100 Meters
We can simplify this :
1 68/100 Meters
EDIT :
We can simplify this even more :
Lets divide both sides by 2 :
34/50
AND we can do it again :
So divide by 2 on both sides :
17/25
And don't forget to add the 1 back into it :
1 17/25
And for the decimal form it is just what we found already :
1.68 Meters
I hope this helps!

100 people went to a picnic. 32 people got sick with food poisoning. The Public HealthDepartment narrowed it down to either the chicken salad or the cream pie. They determined that80 people ate chicken salad, 75 people ate cream pie, 33 people ate chicken salad cream pie anddid not get sick, 5 ate neither food and did not get sick, 40% of the people who ate chicken saladgot sick, and 36% of the people who are cream pie got sick. Was it the chicken salad or thecream pie
Answer:
It was the chicken salad.
Step-by-step explanation:
If you multiply each amount of people that ate one or the other and how many got sick, you get:
Chicken salad: 32
Cream pie: 27
And 32 people got sick so it must be the chicken salad.

Using the given equation find the missing coordinates of the points and then find the slope of the line for each equation y= 0.3x + 1; A(...;9), B(5;...) The slope is
Answer:
[tex]A = (\frac{80}{3},9)[/tex]
[tex]B = (5,2.5)[/tex]
The slope is 0.3
Step-by-step explanation:
Given
[tex]y = 0.3x + 1[/tex]
[tex]A = (-,9)[/tex]
[tex]B = (5,-)[/tex]
Required:
Fill in the gap and calculate the slope
In [tex]A = (-,9)[/tex]
[tex]y = 9[/tex] and x is ??
Substitute 9 for y in [tex]y = 0.3x + 1[/tex]
[tex]9 = 0.3x + 1[/tex]
Collect Like Terms
[tex]0.3x = 9 - 1[/tex]
[tex]0.3x = 8[/tex]
[tex]x = \frac{8}{0.3}[/tex]
[tex]x = \frac{80}{3}[/tex]
So:
[tex]A = (-,9)[/tex]
[tex]A = (\frac{80}{3},9)[/tex]
In [tex]B = (5,-)[/tex]
[tex]x = 5[/tex] and y is ??
Substitute 5 for x in [tex]y = 0.3x + 1[/tex]
[tex]y = 0.3 * 5 + 1[/tex]
[tex]y = 1.5 + 1[/tex]
[tex]y = 2.5[/tex]
So:
[tex]B = (5,-)[/tex]
[tex]B = (5,2.5)[/tex]
Calculating the slope (m)
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
[tex]m = \frac{2.5-9}{5 - \frac{80}{3}}[/tex]
[tex]m = \frac{-6.5}{\frac{15- 80}{3}}[/tex]
[tex]m = \frac{-6.5}{\frac{-65}{3}}[/tex]
[tex]m = \frac{-6.5*3}{-65}[/tex]
[tex]m = \frac{-19.5}{-65}[/tex]
[tex]m = 0.3[/tex]
