30 POINTS IF ANSWERED QUICKLY!!! The contractor in charge of the roofing project is trying to make the job the most cost effective for the homeowners. In order to cut back on the cost of supplies, he decides that a ceiling in the garage is not necessary. In other words, there will not be a barrier built between the garage and the roof. In two or more complete sentences, explain how these changes affect the model for the area of the roof's entire surface.
Answer:
Step-by-step explanation:
This will increase the roofs area by the garages area because, if the contractor does not put a roof to the garage then the garage can be considered part of the roof. This means that the roof's area is the normal area of the roof plus the area of the garage

Which value of x is a solution of the inequality?
x−(−3)≥7
x=−5
x=2
x=3.5
x=8
REAL ANSWERS ONLY PLEASE :)
Answer:
Okay so i am pretty sure it would be x=-5
Step-by-step explanation:
Answer:
B) x=8
Step-by-step explanation:
x − (−3) ≥7
Subtracting a negative is like adding
x + (3) ≥7
Subtract 3 from each side
x +3 −3 ≥7-3
x ≥4
X must be greater than or equal to 4
The only value given that is greater than or equal to 4 is 8

Se hizo un estudio estadístico sobre la duración de una marca de pilas. Los resultados, en horas, de una muestra de 15 pilas son: 20, 22, 25, 21, 22, 20, 23, 21, 24, 22, 24, 21, 23, 22, 21. Construye una tabla de frecuencias absolutas y relativas. a. Calcula las frecuencias absolutas y relativas acumuladas. b. ¿Qué porcentaje de pilas dura menos de 22 horas? Rta: sumo los hi < 22: 0,13 + 0,27 = 0,4 x 100% = 40% c. ¿Qué porcentaje de pilas dura menos de 21 horas? Rta: los hi < 21: 0,13 x 100% 13,33%
There is a bag with only milk and dark chocolates.
5
The probability of randomly choosing a dark chocolate is 1
12
There are 25 dark chocolates in the bag and each is equally likely to be chosen.
Work out how many milk chocolates there must be.
Answer:
There are 300 milk chocolates in the bag.
Step-by-step explanation:
Since there is a bag with only milk and dark chocolates, and the probability of randomly choosing a dark chocolate is 1/12, if there are 25 dark chocolates in the bag and each is equally likely to be chosen, to determine how many milk chocolates there must be the following calculation must be performed:
1 = 25
12 = X
12 x 25/1 = X
300/1 = X
300 = X
Therefore, there are 300 milk chocolates in the bag.

Find the value of each variable given the triangle.
How I solve this
Answer:
m∠1 = 108°
m∠2 = 72°
Step-by-step explanation:
By applying triangle sum theorem in the given triangle,
Sum of all interior angles = 180°
38° + 70° + m∠2 = 180°
m∠2 = 180° - 108°
= 72°
Since, angles 1 and 2 are the linear angles,
Therefore, m∠1 + m∠2 = 180°
m∠1 + 72° = 180°
m∠1 = 180° - 72°
m∠1 = 108°

What is the measure of <C? Round your answer to the nearest tenth of a degree.
A 73.4
B 74.1
C 106.6
D 100.7
Given:
In triangle [tex]ABC, AB=9,BC=4,AC=7[/tex].
To find:
The measure of angle C.
Solution:
We have, [tex]AB=9,BC=4,AC=7[/tex]. It means [tex]c=9,a=4,b=7[/tex].
According to the law of cosines:
[tex]cos C=\dfrac{a^2+b^2-c^2}{2ab}[/tex]
[tex]cos C=\dfrac{4^2+7^2-9^2}{2(4)(7)}[/tex]
[tex]cos C=\dfrac{16+49-81}{56}[/tex]
[tex]cos C=\dfrac{-16}{56}[/tex]
Taking cos inverse on both sides, we get
[tex]C=cos^{-1} \dfrac{-16}{56}[/tex]
[tex]C=106.60155[/tex]
[tex]C\approx 106.6[/tex]
Therefore, the correct option is C.

Answer:
962.5 ft²
Step-by-step explanation:
Area of landing pad = Area of circle
d = 35 ft, r = 35/2 ft
Area = [tex]\pi r^2[/tex]
[tex]\pi r^2[/tex] = [tex]\frac{22}{7} * \frac{35}{2}* \frac{35}{2}[/tex]
= 962.5 ft²
Thus area of landing pad = 962.5 ft²
