Answer:
14cm
Step-by-step explanation:
All side lengths in a cube will be 7 as the properties of a cube are such that all the side lengths are the same.
Think of the longest line in a cube as a hypotenuse on a triangle.
[tex]7^{2} + 7^{2} = c^{2}[/tex]
49 + 49 = [tex]c^{2}[/tex]
[tex]c^{2}[/tex] = 98
c = [tex]\sqrt{98}[/tex]
[tex](\sqrt{98})^{2} + (\sqrt{98} )^{2}[/tex] = [tex]c^{2}[/tex]
[tex]c^{2}[/tex] = 98 + 98
[tex]c^{2}[/tex] = 196
c = [tex]\sqrt{196}[/tex]
c = 14
The longest line in a cube that has a side length of 7cm is 14cm.
A local charity receives 1/3 of funds raised during a craft fair and a bake sale. The craft fair raised $252.60. The total amount given to charity was $137.45. How much did the bake sale raise?
Answer:
$159.75
Step-by-step explanation:
137.45/252.60 + x = 1/3
252.60 + x = 412.35
x = 412.35 - 252.60
x = 159.75
Answer:
297.2
Step-by-step explanation:
549.8 ÷ 4 = 137.45
549.8 - 252.60 = 297.2

Answer:
a). -6x³ - 12x² b). -12 c). 12
Step-by-step explanation:
a). (g x f)(x) can also equal f(g(x))
= f (2x +4)
= -3x² (2x+4)
= -6x³ - 12x²
b). f(g(-1))
g(-1) = 2(-1) + 4
= -2 + 4
= 2
f(2) = -3x²
= -3(2)²
= -12
c). g(h(3))
h(3) = 3x-1/2
= 3(3) - 1 / 2
= 4
g(4) = 2x + 4
= 2(4) + 4
= 12

A rectangular piece of paper with length 39 cm and width 20 cm has two semicircles cut out of it, as shown below.Find the area of the paper that remains. Use the value 3.14 for π , and do not round your answer. Be sure to include the correct unit in your answer.
Answer:
The area of the piece of paper is 466 cm²
Step-by-step explanation:
First you would want to find the area of the rectangle
39x20=780 cm²
Both semi-circles are the same, so you can just find the area of the whole circle
The diameter is 20 cm so you would use 10 as the radius
A=πr²
A=3.14x10²
A=3.14x100
A=314
Then you have to subtract the area of the circle from the area of the rectangle.
780-314=466
The area of the piece of paper is 466 cm²

If your driving 60miles an hour and you drive for 1hour how far do you travel?
Answer:
60 miles
Step-by-step explanation:
There are two ways to solve this:
1. They tell you that you drive at 60 miles an hour, so , in an hour, you drive 60 miles.
2. Is the way you should use in the future:
Distance = speed * time
Substitute the speed and times.
Distance = 60 * 1
Thus, you drive 60 miles in one hour
The distance that should be traveled be 60 miles
As we know that
[tex]Speed = \frac{distance}{time}[/tex]
Here
speed be 60 miles per hour
And, the time should be one hour
So, the distance should be
[tex]= 60\ miles\ per hour \times one\ hour[/tex]
= 60 miles
Therefore the distance that should be traveled be 60 miles

What percent of the time will the point be in the shaded region
Answer:
29.4%
Step-by-step explanation:
the whole cirlce is 360 degrees which means 100%
to find the percentage of the shaded area, multiply the degrees by 100
⇒ 10.6 x 100 = 10600
then take the product and divide by 360
⇒ 1060 ÷ 360
⇒ 29.44
round to the nearet tenth of a percent
⇒ 29.4

In isosceles triangle JKL, JK KL. If the measure of
angle J is 47°, find the measure of angle K.
*Note: Do NOT include the degree in your answer.
Answer:
86
Step-by-step explanation:
Since ∆JKL is an isosceles triangle, it's base angles (<L and <J) would be equal to each other.
<L is opposite to side JK, <J is opposite to side KL.
m<J is given as 47°. Therefore,
m<L = m<J = 47°
m<L = 47°
m<J + m<L + m<K = 180° (sum of triangle)
47° + 47° + m<K = 180° (substitution)
94° + m<K = 180°
m<K = 180° - 94°
m<K = 86°
What is the equation of a line .........
Answer:
y = -x + 2, B is the answer
Step-by-step explanation:
If slope is -1, the equation is y = -x+b
Plug in (3,-1) into that equation.
-1 = -3 + b
b = 2

The rectangle shown has a perimeter of 98 cm and the given area. Its length is 7 more than 5 times its width. Write and solve a system of equations to find the dimensions of the rectangle.
Answer:
35 is its width and 63 is its length.
Step-by-step explanation:
7 x 5 = 35 and 98 - 35 equals 63 which is the length.

Find the answer for m∠EFD
Given:
In triangle DEF, [tex]DE = EF[/tex] and [tex]m\angle 98^\circ[/tex].
To find:
The measure of angle EFD.
Solution:
In triangle DEF,
[tex]DE = EF[/tex] (Given)
It means triangle DEF is an isosceles triangle.
[tex]m\angle EDF=m\angle EFD[/tex] (Base angles of an isosceles triangle are equal)
Using angle sum property in triangle DEF, we get
[tex]m\angle DE F+m\angle EFD+m\angle EDF=180^\circ[/tex]
[tex]98^\circ +m\angle EFD+m\angle EFD=180^\circ[/tex]
[tex]2m\angle EFD=180^\circ-98^\circ[/tex]
[tex]2m\angle EFD=82^\circ[/tex]
Divide both sides by 2.
[tex]m\angle EFD=\dfrac{82^\circ}{2}[/tex]
[tex]m\angle EFD=41^\circ[/tex]
Therefore, the measure of angle EFD is 41 degrees.

Answer:
2.4 cm
Step-by-step explanation:
We know the length of segment AB and the length of segment BC. To find their midpoints, we can divide their length by 2.
Let's find the midpoint of AB.
Segment AB: 10 cm Midpoint of AB: 10/2 = 5 cmNext let's find the midpoint of BC.
Segment BC: 5.2 cmMidpoint of BC: 5.2/2 = 2.6 cmIn order to find the difference between these midpoints, we can subtract the midpoint of AB by the midpoint of BC.
5 cm - 2.6 cm = 2.4 cmTherefore, the difference between the midpoints of AB and BC is 2.4 cm.
