Alexis is knitting a blanket 2 meters long. Every 2 decimeter, she changes the color of the yarn to make stripes. How many stripes will the blanket have? Explain

Answers

Answer 1

Answer:

Convert 2 meters into decimeters. move the decimal over one places.

2m=20 decimeters. 20 decimeters of blanket divided by 2 decimeters of color per stripe (20/2)= 10 stripes.

What is the simplified form of the expression 3[14/(4^2 - 3^2) - 5]

a. -9
b. 27
c. 21
d. 6

Answers

ANSWER

A.
$- 9$

EXPLANATION

The given expression is

$3( \frac{14}{ {4}^(2) - {3}^(2) } - 5)$

Recall that,

${a}^(2) - {b}^(2) = (a - b)(a + b)$

We apply the difference of two squares formula to factor the numerator to obtain,

$= 3( (14)/( (4 - 3)(4 + 3) ) - 5)$
We simplify the factors in the denominator to get,

$= 3( (14)/( (1)(7) ) - 5)$
Let us cancel out the common factors now to get,

$= 3( 2 - 5)$

This will give us,

$= 3( - 3) = - 9$

The correct answer is A.

ricky found a beetle that has a body one fourth the length of the fraction strips used in problem 1.2. how many beetle. how many beetle bodies placed end to end would have a total length equal to the length of a fraction strip. ricky drew 13 paper beetle bodies end to end each the same length as the one found. how many fraction strips long is ricky line of beetle bodies.

Answers

1/4 of 1/4

= 1/8

13 x 1/8

= 13/1 x 1/8

= 1 5/8

therefore there are 1 and 5/8 in the line of rickys fraction strips.

on a fraction strip line this is 13/8

Mr. Hawkins is covering a room in carpet. The room measures 14 feet by 12 feet in a rectangular shape. Each square foot of carpet costs $2.90. What is the cost of carpeting the room?

Answers

Answer:

The total cost of adding wallpaper to the room is $487.20

Step-by-step explanation:

Basically, how I got the answer is:

1. The shorter sides of the rectangle are 12 and the longer sides are 14.

2. The formula for a rectangle is A = l x w. The "l" means length and the "w" means width. 14 is the length and 12 is the width. So you should now have A = 14 x 12. If you multiply 14 by 12, you will get 168.

3. Since 1 square foot of carpet costs $2.90, then you should multiply by 168, which will give you $487.20 and that's pretty much it.

Hope this helps! :)

first lets find the area of the floor.

A=l*w where l=length and w=width
Plug in the data
A=14*12
A=168ft²

If 1 square foot of carpet is 2.90$, then 168 square feet are...

1 sqft 168sqft
_______ = ________
2.90$ x$

Cross multiply
1x=487.20
divide both sides by 1
x=487.20 dollars

Answer= $487.20

Please help urgent plzz1.find the mean of the data set excluding multiple of number 10 between 1 to 50?

2.find the mean of the data set excluding multiple of number 3 between 1 to 10?

Answers

This can be done quickly using Excel or a scientific calculator. For problem no. 1, the data that are multiples of 10 in the set are 10, 20, 30, 40 and 50 and the number of data points in the set are 45 since the data set is from 1-50 excluding the 5 numbers that are multiples of 10.

Mean=[(sum of all numbers from 1 to 50)-10-20-30-40-50]/[50-5]=25

The second problem is similar. The multiples of 3 here are 3, 6 and 9. There are 10-3 data points.

Mean = [(sum of numbers from 1-10)-3-6-9)]/[10-3]=5.2857

Eduardo is building a sandbox that has an area of 84 square feet. What are the possible whole number measurements for the length and width of the sandbox?

Answers

To find the area, of a rectangle, you multiply length by width. Therefore, any factor pairs of 84 would be possible measurements for the length and width of the sandbox.
length=1ft, width=84ft (1x84=84)
length=2ft; width=42ft (2x42=84)
length=3ft; width=28ft (3x28=84)
length=4ft; width=21ft (4x21=84)
length=6ft; width=14ft (6x14=84)
length=7ft; width=12ft (7x12=84)
And switching the numbers around gives you more possibilities.
length=12ft; width=7ft
length=14ft; width=6ft
length=21ft; width=4ft
length=28ft; width=3ft
length=42ft; width=2ft
length=84ft; width=1ft
12 total possible whole number pairs for the length and width of the sandbox.
See how that works? Easy as pie, so long as you have the patience to find all the factors.
I hope this helps!
