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

(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

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.

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.

1. Emmanuel bought 28 lb of potting soil this week. This amount is 4 lb more than twice the amount of potting soil he bought last week. Answer the following questions to find the number of pounds of soil Emmanuel purchased last week.
(a) What is the unknown information?
(b) Let p represent the unknown information. Write an equation to model the problem.
(c) Which number, 10, 11, or 12, will solve the equation in Part (b)? Show your work.
(d) How many pounds of potting soil did Emmanuel buy last week?
Answer:
plz help me I beg you
Answer:
1.) Amount of potting soil purchased last week.
2) 2p + 4 = 28
3.) 12 lbs
Step-by-step explanation:
1.) The unknown information is what we intend to find out using the information given, which is the amount of potting soil Emmanuel bought last week.
2.)
Let amount of potting soil bought last week = p
Amount bought this week = 2p + 4
Since amount bought this week = 28
Hence, we have ;
28 = 2p + 4
28 - 4 = 2p
24 = 2p
p = 24 / 2
p = 12
If a six-sided die(1-6) and a ten-sided die(1-10) are rolled simultaneously, then what is the probability of rolling both with a number greater than four
Answer:
[tex]Pr = 0.20[/tex]
Step-by-step explanation:
Given
[tex]n_1 = 10[/tex] ---- 10 sided
[tex]n_2 = 6[/tex] --- 6 sided
Required
[tex]P(x_1,x_2 > 4)[/tex]
First, list out the sample space
[tex]S = \{(1, 1) (1, 2) (1, 3) (1, 4) (1, 5) (1, 6)(2, 1) (2, 2) (2, 3) (2, 4) (2, 5) (2, 6)[/tex]
[tex](3, 1) (3, 2) (3, 3) (3, 4) (3, 5) (3, 6) (4, 1) (4, 2) (4, 3) (4, 4) (4, 5) (4, 6)[/tex]
[tex](5, 1) (5, 2) (5, 3) (5, 4) (5, 5) (5, 6) (6, 1) (6, 2) (6, 3) (6, 4) (6, 5) (6, 6)[/tex]
[tex](7, 1) (7, 2) (7, 3) (7, 4) (7, 5) (7, 6) (8, 1) (8, 2) (8, 3) (8, 4) (8, 5) (8, 6)[/tex]
[tex](9, 1) (9, 2) (9, 3) (9, 4) (9, 5) (9, 6) (10, 1) (10, 2) (10, 3) (10, 4) (10, 5) (10, 6)\}[/tex]
[tex]n(S) = 60[/tex] --- total outcomes
The event that the outcome of both is greater than 4 is:
[tex]x_1,x_2> 4 = \{(5, 5) (5, 6)(6, 5) (6, 6)(7, 5) (7, 6) (8, 5) (8, 6)(9, 5) (9, 6) (10, 5) (10, 6)\}[/tex]
[tex]n(x_1,x_2>4) = 12[/tex]
So, the probability is:
[tex]Pr = \frac{n(x_1,x_2>4)}{n(S)}[/tex]
[tex]Pr = \frac{12}{60}[/tex]
[tex]Pr = 0.20[/tex]

find the equation of the line below (1,-2) (2,-4) *20 brainliest points* *pls help*
Answer:
y= -2x
Step-by-step explanation:
First find the slope
m = ( y2-y1)/(x2-x1)
= ( -4- -2)/(2-1)
= ( -4+2)/( 2-1)
-2/1
-2
Using y = mx+b where m is the slope and b is the y intercept
y = -2x+b
Substitute a point into the equation
-2 = -2(1)+b
-2 = -2+b
b=0
y= -2x
