Answer:
Step-by-step explanation:
By the Isosceles Triangle Theorem, angle O and angle M are congruent because the sides across from each of these angles are congruent. therefore, O = M = 4y - 15. Since, by the Triangle Angle-Sum Theorem all the angles of a triangle have to add up to equal 180 AND angle O and angle M are the same:
7y + 4y - 15 + 4y - 15 = 180 and
15y - 30 = 180 and
15y = 210 so
y = 14. Plug 14 in for y in 7y and get that
∠N = 98°

Find the percent of change from 48 people to 71 people. Round to the nearest tenth of a percent if necessary.
Step-by-step explanation:
Here, the number of people has beed increased.
→ Number of people increased = 71 - 48
→ Number of people increased = 23
[tex] \to \% \: change = \left ( \dfrac{23}{71} \times 100 \right ) \: \% \\ [/tex]
[tex] \to \% \: change = \left ( \dfrac{2300}{71} \right ) \: \% \\ [/tex]
[tex] \red{ \to \% \: change = 32.39 \: \%} \\ [/tex]
Therefore, percentage change is 32.39 %.

new community center. How I Find the prime factorization of the number 24
Answer:
2*2*2*3
or
2^3 * 3
Step-by-step explanation:
24 = 4*6
But 4 and 6 aren't prime
24 = 4*6 = (2*2) * (2*3)
All these numbers are prime
24 = 2*2*2*3 or with exponents = 2^3 * 3

Step-by-step explanation:
x = 10sqrt(2)*cos(60) = 5sqrt(2) = 7.07 approx.
y = 10sqrt(2)*sin(60) = 10sqrt(2)*sqrt(3)/2 = 5sqrt(6)=12.25 approx.
True or False:
(1, 2) is a solution to the following system of equations:
5x +y=7
7x – 2y = 3
A) True
B) False
Step-by-step explanation:
LHS = 5x+y =5(1)+2= 5+2= 7
RHS = 7
since LHS= RHS
LHS = 7x-2y =7(1)-2(2)=7-4=3
RHS = 3
since LHS=RHS
(1, 2) is a solution to the following system of equations.
True

The population of a school is 800 students and is increasing at a rate of 2% per year. Write
an exponential growth function, then find the population of the school after 9 years.
Why is it not giving the right answer
Answer:
After 9 years the population would be 956. The exponential growth function would be [tex]x(956)=800_{0} (1+\frac{2}{100})^{9}[/tex]
Step-by-step explanation:
y=a(1+r)x
a = initial amount
r = growth rate as a decimal
x = number of time intervals passed (days, months, years)
y = amount after x time
This formula is used to express a function of exponential growth.
Can someone help me solve question 2 and 3?
Answer:
Question 2 = 15 drinks
Question 3 = 7/12
Step-by-step explanation:
Question 2:
For every drink, there are three sizes

There are 5 flavors
Multiply each side by 5
5:15
15 drinks
Question 3:
5 red, 6 yellow, 8 blue, 3 orange, 2 purple
Possible outcomes = 5 + 6 + 8 + 3 + 2 = 24 possible outcomes
Favourable outcomes = 6 + 8 = 14 favourable outcomes

Tarin's dog had 12 toys, but he lost 3 of them. Tarin's dog now has 8 fewer toys than her cat. How many toys does Tarin's cat have?

17
Step-by-step explanation:
12-3+8= 17
may I please have help ! Thank you so much .!
The equation is 15*w*14 = 2730
We simply multiply length, width and height to get the volume of the rectangular block.
That equation becomes 210w = 2730 because 15*14 = 210
From here, we divide both sides by 210
You should end up with w = 13
As a check, 15*w*14 = 15*13*14 = 2730 which confirms we have the correct replacement for w.
1. Find measure of angle GBC
A. 55°
B. 125°
C. 45°
D. 60°
(Show work)
Answer:
A. 55°
Step-by-step explanation:
So the line goes through two angles, 125° and 55°
Lets check, does the angle look larger than 90°
Remember, 90° mean the line is perpendicular, or goes straight up.
I see that it is not. The angle that is less than 90° (55°) is correct.
