Answer:
A special right triangle is a right triangle with some regular feature that makes calculations on the triangle easier, or for which simple formulas exist. For example, a right triangle may have angles that form simple relationships, such as 45°–45°–90°. This is called an "angle-based" right triangle.

Sixty students got off a school bus. 30% of them were wearing college
sweatshirts. How many were not wearing college sweatshirts?
Answer:
42 students
Step-by-step explanation:
A percentage can be converted to a decimal. 30% -> 0.30.
Now multiply 60x0.30, which is 18.
So 18 were wearing sweatshirts. But that's not what we need.
Subtract 60-18, which is 42.
42 were not wearing sweatshirts.

Tasha has foam blocks stored in a box that measures 314 ft long by 3 ft wide by 1 ft tall. Each foam block is a cube with 14 -ft edge length.
Answer:
3Step-by-step explanation:
Since we are not tole what to find, we can as well calculate the total number of foam blocks.
Volume of the box = Length * Width * Height
Volume of the box = 314ft * 3ft * 1ft
Volume of the box = 942ft^3
Volume of the cube with edge 14ft
Volume of the cube = 14 * 14 *14
Volume of the cube = 2,744
Total foams in the box = Volume of cube/Volume of box
Total foams in the box = 2744/942
Total foams in the box = 2.9
Total foams in the box is about 3

The measure of an angle is 7°. What is the measure of its supplementary angle?
Answer:
173
Step-by-step explanation:
supplementary means adding up the 2 angles make 180
7+173=180
Answer:
173 degrees
Step-by-step explanation:
Supplementary angles are angles that form 180 degrees. So subtract 7 from 180 to get the measure of the other angle (which would be 173 degrees).

help help help pls pls
Answer:
x ≈ 7.1
Step-by-step explanation:
The circumference of this circle is 2πx.
65/360 of that circumference is said to be 8
so we can solve x from
65/360 · 2πx = 8
which can be simlified to
2πx = 8 · 360/65
πx = 288/13
x = 288 / (13π) ≈ 7.1
Another company charges $8 per month and $0.03 per minute used. Which equation below best respresents the total cost for the month, c, for m miuntes used?
Answer: c = 8 + 0.03m
Step-by-step explanation:
From the question, we are informed that a company charges $8 per month and $0.03 per minute used.
The equation that best respresents the total cost for the month, c, for m miuntes used will be:
c = 8 + (0.03 × m)
c = 8 + (0.03m)
c = 8 + 0.03m
For example if 10 minutes was used, the cost will be:
c = 8 + 0.03m
c = 8 + (0.03 × 10)
c = 8 + 0.3
c = $8.3

which answer choice is equivalent to the expression (x+2)^2 - 6x+2?
a. x^2 - 2x+8x
b. x^2 - 2x+6
c. x^2 - 6x+4
d. -5x^2 +6
Answer:
(x+2)^2 - 6x+2
(x+2)^2 = (x+2).(x+2)
= x(x+2) + 2(x+2)
= xx + x2 + 2x +4 ( x2 = 2x)
= x^2+ 4x +4
(x+2)^2 - 6x+2
x^2+ 4x +4- 6x+2
x^2+ 4x - 6x+2 +4
x^2- 2x+2 + 6 (b)

We have the height and distance from the window, so we need to find c
[tex]10^{2}[/tex]+[tex]24^{2}[/tex]=[tex]c^{2}[/tex]
100+576= 676
[tex]\sqrt{676}[/tex] = 26

do you understand this one?
Answer:
3rd one
Step-by-step explanation:
[tex]sin = \frac{opposite}{hypotenuse}[/tex]
find sin f
the opposite of f is 96 and the hypotenuse is 100
so [tex]sinF=\frac{96}{100} or.96[/tex]
find sin g
the opposite of g is 28 and the hypotenuse is 100
so [tex]sinG=\frac{28}{100} or.28[/tex]
so your correct answer would be the third one

What does y=?? 10 POINTS
y = [ ? ]
5y-20
2y+25
Answer:
1st one)
y = 4
2nd one)
y = -12.5
Step-by-step explanation:
5y - 20 = 0
add 20 on both sides:
⇒ 5y - 20 + 20 = 0 + 20
⇒ 5y = 20
divide 5 on both sides
⇒ [tex]\frac{5y}{y} = \frac{20}{5}[/tex]
⇒ y = 4
2y + 25 = 0
subtract 25 on both sides
⇒ 2y + 25 - 25 = 0 - 25
⇒ 2y = -25
divide 2 on both sides:
⇒ [tex]\frac{2y}{2} = \frac{-25}{2}[/tex]
⇒ y = -12.5
