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

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).

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)

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

Answer:
Area of the remaining board = 403 cm²
Step-by-step explanation:
Area of the remaining paper board = Area of the rectangle - Area of the semicircle
Area of the rectangle = Length × Width
= 28 × 20
= 560 cm²
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
= [tex]\frac{1}{2}(3.14)(\frac{20}{2})^2[/tex]
= 3.14 × 50
= 157 cm²
Area of the remaining board = 560 - 157
= 403 cm²

Answer:
The ladder needs to be 26 ft long.
Step-by-step explanation:
So pythag is [tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex]
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

Which point lies on a circle with a radius of 5 units and center at P(6, 1)?
A. Q(1,11)
B. R (2,4)
C. S (4, -4)
D. T(9,-2)
Answer:
B
Step-by-step explanation:
An equation of a circle:
(x - a)² + (y - b)² = r²
(a; b) - a coordinates of a center
r - a radius
r = 5; P(6; 1) ⇒ a = 6 and b = 1
therefore
(x - 6)² + (y - 1)² = 5²
check:
A) Q(1; 11)
L = (1 - 6)² + (11 - 1)² = (-5)² + 10² = 25 + 100 = 125
R = 25
L ≠ R
B) R(2; 4)
L = (2 - 6)² + (4 - 1)² = (-4)² + 3² = 16 + 9 = 25
R = 25
L = R - CORRECT
C) S(4; -4)
L = (4 - 6)² + (-4 - 1)² = (-2)² + (-5)² = 4 + 25 = 29
R = 25
L ≠ R
D) T(9; -2)
L = (9 - 6)² + (-2 - 1)² = 3² + (-3)² = 9 + 9 = 18
R = 25
L ≠ R
Answer: B) R(2; 4).

Answer: -5
Step-by-step explanation:
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
