Please help meeeeee
Answers
Answer:
a. m<DAB = 36°
b. m<B = 54°
c. m<C = 74°
Step-by-step explanation:
a. m<DAB = m<CAB + m<CAD
m<DAB = 20° + 16° (substitution)
m<DAB = 36°
b. m<B = 180° - (90° + m<DAB)
m<B = 180° - (90° + 36°) (substitution)
m<B = 54°
c. m<C = 180° - (90° + m<CAD)
m<C = 180° - (90° + 16°) (substitution)
m<C = 74°

Answers
Answer:
.23, 34%, 18/25
Step-by-step explanation:
34% = 0.34 (2)
.23 = 0.23 (1)
18/25 = 0.72 (3)
Which shows a correct way to find the product?
(−8)(0.09)(−125)
A.
(−8)(0.09)(−125) = (−8)(−125)(0.09)
= (1,000)(0.09)
= 90
B.
(−8)(0.09)(−125) = (−8)(−125)(0.09)
= (−1,000)(0.09)
= −90
C.
(−8)(0.09)(−125) = (−8)(−125)(−8)(0.09)
= (1,000)(−0.72)
= −720
D.
(−8)(0.09)(−125) = (−8)(−125)(−8)(0.09)

A square has side length represented by X +4 inches write an expression to represent the area. Express your answer as a trinomial.
Answers
Answer:
[tex]A=(x^2+16+8x)\ \text{inches}^2[/tex]
Step-by-step explanation:
Given that,
The side length of a square, l = (x+4) inches
We need to find an expression to represent the area of the square.
The area of a square is given by :
[tex]A=\text{side}^2[/tex]
So,
[tex]A=(x+4)^2\\\\A=(x^2+16+8x)\ \text{inches}^2[/tex]
So, the area of the square is [tex](x^2+16+8x)\ \text{inches}^2[/tex].

You rent an apartment that costs $800 per month during the first year, but the rent is set to go up $170 per year. What would be the monthly rent during the 8th year of living in the apartment?
Answers
The monthly rent during the 8th year of living in the apartment will be $2160.
What is the linear system?A linear system is one in which the parameter in the equation has a degree of one. It might have one, two, or even more variables.
You rent an apartment that costs $800 per month during the first year, but the rent is set to go up by $170 per year.
Then the monthly rent during the 8th year of living in the apartment will be
Let y be the monthly rent and x be the number of years.
Then we have
y = 170x + 800
The rent after 8 years, then the rent will be
y = 170 × 8 + 800
y = 1360 + 800
y = $ 2160
Thus. the monthly rent during the 8th year of living in the apartment will be $ 2160.
