Leena bought 14 yards of wire. How many inches of wire did she buy? (1 yard = 36 inches)
Answer:
504
Step-by-step explanation:
So, lets calculator this.
For each yard, there are 36 inches.
There are 14 yards.
To find the amount of inches in this 14 yards, we need to multiply 14 by 36:
14x36
=
504
So there are 504 inches of wire in 14 yards.
Answer:
504
Hope this helps! :)
Answer 46
Step-by-step explanation:
14×36 1 yard=36 inches

Step-by-step explanation:
A map of a highway has a scale of 2 inches equals 33 miles. The length of the highway on the map is 6 inches. There are 11 rest stops equally spaced on the highway, including one at each end. You are making a new map with a scale of 1 inch equals 30 miles. How far apart are the rest stops on the new map?
(nvm)
Answer:
The answer is "0.975"
Step-by-step explanation:
Please find the complete question in the attched file.
Find the remaining distance inside the original map
[tex]\to \frac{9}{6}=1.5 \ in[/tex]
Dividing the value by 6 because there are 7 rest stop:
[tex]\to \frac{2 \ inches}{39 \ inches} =\frac{1.5 \ inches}{x \ miles}\\\\\to x=39 \times \frac{1.5}{2}\\\\\to x=29.25 \ miles[/tex]
Finding the diatance of the rest stop in the new map
Using proportion:
[tex]\to \frac{1 \ inches}{30 \ miles} =\frac{x \ inches}{ 29.25 \ miles}\\\\\to x= \frac{29.25}{30}\\\\\to x=0.975 \ in[/tex]

I need help with this question
Answer:
128π²
Step-by-step explanation:
The equation for a cylinders volume is V=πr²h
So that means that we square r which is 4, we get 16. Then we multiply 16 by the height which is 8. This gives us 128. The last step is to multiply by pi so we get 128π.
Collete mapped her vegetable garden on the graph below. Each unit represents 1 foot. Collete plants an 8-foot row of lettuce in the garden. Which points could tell where the row of lettuce starts and ends?
Answer:
(-4,-1) and (-4,7)
Step-by-step explanation:
If Collete planted a row of lettuce, that means their coordinates must have the same vertical coordinate, or the same horizontal coordinate. Another important characteristic is that between those points, there must have 8 units of separation, because it's an 8-foot row.

Seven gallons of a sugar solution was mixed with 4 gallons of a 80 percent sugar solution to make an 72 percent sugar solution. Find the percent concentration of the first solution. (a) 70% (b) 61% (c) 69% (d) 67%
Answer:
67%
Step-by-step explanation:
Let the percentage of the first solution = x
7 gallons + 4 gallons = 11 gallons
Our system of equation is
Seven gallons of a sugar solution was mixed with 4 gallons of a 80 percent sugar solution to make an 72 percent sugar solution.
7 gallons × x % + 4 gallons × 80% = 72% × 11 gallons
= 7x + 3.2 = 7.92
Collect like terms
7x = 7.92 - 3.2
7x = 4.72
x = 4.72/7
x = 0.6742857143
Converting to percentage
0.6742857143 × 100
= 67.42857143%
Approximately, the percent concentration of the first solution is 67%

A trader made a profit of 24% by selling an article for #372 how much should he have sold it to make a profit of 48%
Answer: #444
Step-by-step explanation:
First find the original selling price of the article.
When sold for #372 the profit was 24%. Assume the original price is x.
372 = x + 24% * x
372 = 1.24x
x = 372 / 1.24
= #300
If he wanted to make a profit of 48% he should have sold for:
= Original price + (original price * 48%)
= 300 + (300 * 48%)
= #444
What does 2π/3 equal and cos2π/3 equal?
Answer:
Step-by-step explanation:
2π/3 radians is equivalent to
2π 180°
-------- * ---------- = 120°
3 π rad
This angle (120°) is 30° past 90°. The 'opposite side' of the triangle formed by this ray of length 1 is √3 and the 'adjacent side' is 1.
adj side -1
cos 120° is in Quadrant II. cos 120° = --------------- = ---------

In this rectangle, find m angle DEC.
Please help me!!!!
Answer:
118°
Step-by-step explanation:
EDC is 31° and ECD has the same measure. (Triangle DEC is isosceles)
The total sum of angle EDC and ECD is 31 + 31 = 62°
The total sum of all the angle measures in a triangle is 180°, so just subtract 62 from 180 to get the measure of angle DEC.
180 - 62 = 118°
4 Stretch Your Thinking: Brian has some boxes of paper clips. Some boxes hold 10 clips and some boxes hold 100. He has some paper clips left over. He has three more boxes with 100 paper clips than he has boxes with 10 paper clips. He has two fewer paper clips left over than he has numbers of boxes with 100 paper clips. What number of paper clips could he have?
Answer:
Any of {412, 523, 634, 745, 856, 967, 1078, 1189}
Step-by-step explanation:
Relations are given between the number of 10-clip boxes, the number of 100-clip boxes, and the number left over. We assume there are at least one of each size box, and that there are fewer than 10 clips left over. (10 could be put into another box.)
__
Let h represent the number of 100-clip boxes. Then h-3 is the number of 10-clip boxes, and h-2 is the number of clips left over. The total number of paperclips is ...
10(h -3) +100h +(h -2) = 111h -32
In addition, we require ...
h -3 > 0 and h-2 < 10
3 < h < 12 . . . . . . . rearranging these inequalities
So, Brian could have 111h -32 paper clips, where 3 < h < 12. That could be any of {412, 523, 634, 745, 856, 967, 1078, 1189} paper clips.

Answer:
x = 29.69
Step-by-step explanation:
Since the Adjacent side of the given angle 38, is given, and opposite needs to be found out, we will us the Tangent ratio:
Tan(38) = [tex]\frac{x}{38}[/tex]
=> To isolate x all by itself, multiply 38 from the right side of "=", on both sides;
Tan(38) * 38 = x
29.69 = x
