Step-by-step explanation:
The population of a certain town was 50,000.In a year,male population
was increased by 5% and female population was increased by 3%. Now
the population beame 52020. Then what was the number of males and
females in the previous year?
olution:- Let the number of males in previous year be x,number of females
Answer: Male population = 26,000
Female population = 24,000
Step-by-step explanation: Male population = X
Female population = Y
x+y=50,000
y=50,000-x-(1st equation)
Again (x+x X 5%) + (y+y X 3%) = 52,020
-> x+5x/100 + y+3y/100 = 52020
-> 100x+5x+100y+3y =52020
________________
100
-> 105x+103y = 52020-( 2nd Equation)
Putting Eq 1 into 2 ,
105x+103 ( 50,000-x)= 52,020
-> 105x + 5,150,000-103x = 52,020
->2x = 52,020-5,150,000
->2x = 52,000
x = 26,000 (Male population)
y = 50,000-26,000
= 24,000 (Female population)

One gram of protein contains 4 calories. One gram of fat contains 9 calories. A snack has 60 calories from p grams of protein and f grams of fat. The equation 4p + 9f = 60 represents the relationship between these quantities. If there are 6 grams of fat in the snack, how many grams of protein are there? Show your reasoning.
Answer:
1.5 grams of protein.
Step-by-step explanation:
The equation that represents the relationship between protein and fat is as follows :
4p + 9f = 60 ....(1)
We need to find the grams of protein are there if there are 6 grams of fat in the snack.
Put f = 6 in the above equation (1).
4p + 9(6)= 60
4p + 54 = 60
Subtract 54 to the both sides,
4p + 54-54 = 60-54
4p = 6
⇒ p = 1.5 grams
It means the snack contains 1.5 grams of protein.

find the nth term of 8,17,26,35,....
Answer:
8 + (n-1)*9
Step-by-step explanation:
In the series, we can see that the difference between 2 consecutive terms is always 9, and the sequence starts at 8.
That means the nth term of the series must be 8 + (n-1)*9
Given A and B are vertical angles with m∠A = 20x + 10 and m∠B = 30x – 10. What is x? 3.6 4 2 9
i will give brainliest
Answer:
Step-by-step explanation:
∠A and ∠B are vertical => ∠A=∠B
20x+10=30x-10
20x-30x= -10-10
-10x= -20
x= -20 / -10 = 20 / 10 = 2
x=2
Good luck!
Answer:
2
Step-by-step explanation:
Ok remember this because its going to appear alot in geometry. Vertical angles are ALWAYS congruent and congruent means when two things are equal/ are the same.
If angle a and b are vertical angles what does that mean?
they are CONGRUENT!
you know A = 20x+ 10 and B= 30x-10
so you can write it as
20x+10 = 30x-10
because Angle A and B equal each other
then get the variable by itself so subtract -20x on both sides
10 = 10x-10
then add 10 to both sides which is
20 = 10x
and divide 10 on both side and 20 divided by 10 is 2
so 2 =x
which is the same as x =2

Rachel bought new school supplies for herself at Target. Pencil packs were $4.75, markers were $6.80, and folders were $8.64. If she bought 7 folders, 2 pencil packs, and 3 packs of markers, how much money did she save if she had a 15% discount coupon?
Answer:
She saved $13.56
Step-by-step explanation:
$8.64 x 7 folders = $60.48
$4.75 x 2 packs of pencils = $9.50
$6.80 x 3 packs of markers = $20.40
$60.48 + $9.50 +$20.40 = $90.38
$90.38 - 15% = $76.82 (76.823)
She saved a total of $13.56 (13.557)
Answer:
Rachel saved $13.56
Step-by-step explanation:
Pencil Packs: 2 x $4.75 = $9.50
Markers: 3 x $6.80 = $20.40
Folders: 7 x $8.64 = $60.48
Add up the costs.
$90.38
Multiply $90.38 by 0.15
13.557
Round to the nearest hundredth.
$13.58

The length of a rectangular room is 4 feet longer than twice the width. If the room’s perimeter is 140 feet, what are the room’s dimensions?
Answer:
Width = 22ft Length = 48ft
Step-by-step explanation:
Length = 2(w) + 4
I personally first picked a random number (20) and I got 128, so I knew I had to pick a larger number.
I skipped up to 22 and this is what I did.
W = 22(2) <--(Since there are two width sides) = 44
L = 2(w) + 4
L = 2(22) + 4
L = 44 + 4 = 48
48(2) <--(Since there are two length sides) = 96
96 + 44 = 140

A soccer coach recorded how many hours, rounded to the nearest hour each of 12 soccer players practiced for last week The box and whisker plot that descubes the ata is displayed
below the first quartile of the data was 75 which statement must be true?
105
12
Exactly 9 of the 12 soccer players prachoed for between 7 and 8 hours last week
Exactly 9 of the 12 soccer players practiced for at least 7 5 hours last week
Exactty 3 of the 12 soccer players practiced for between 7 and 8 hours last week
Exactly 3 of the 12 soccer players practiced for at least 7 5 hours last week
Answer:
The correct option is;
Exactly 3 of the 12 soccer players practiced for at least 75 hours last week,
Step-by-step explanation:
The given information are;
The number of soccer players that practiced = 12 soccer players
The first quartile of the data of the recorded number of hours each soccer player practiced = 75
Therefore, given that that there are 12 soccer players, the number of data points = 12
The value of the 1st quartile is the value of the (n + 1)/4th term
When n = 12, we have;
The 12th quartile = (12 + 1)/4 = 3.25 th term with the values arranged in increasing order;
Therefore, the first quarter has the values for the first 3 players, with the lower practiced hour recorded while the recorded time for the remaining 9 players come after the first quartile;
The correct option is therefore that it must be true that exactly 3 (since we do not represent a player with the remaining fraction of 0.25 in 3.25) of the 12 soccer players practiced for at least 75 hours last week.

4(1-x)+3x=-2(x+1)
GOOD LUCK!!!
Answer:
-6Step-by-step explanation:
Given
4(1 - x) + 3x = -2(x+1)Solving for x
4(1 - x) + 3x = -2(x+1)4 - 4x + 3x = -2x - 24 - x = -2x - 2- x + 2x = - 2 - 4x = - 6Answer:
x = -6
Step-by-step explanation:
4(1 - x) + 3x = -2(x + 1)
~Distribute both sides
4 - 4x + 3x = -2x - 2
~Combine like terms
4 - x = -2x - 2
~Add x to both sides
4 = -x - 2
~Add 2 to both sides
6 = -x
~Divide -1 to both sides
-6 = x

Answer:
Negative StartFraction 7 over 10 EndFractionStep-by-step explanation:
Given the expression [tex]\frac{1}{2} - 1\frac{1}{5}[/tex], we are to find the difference
First convert the mixed fraction [tex]1\frac{1}{5}[/tex] to improper fraction
[tex]1\frac{1}{5}[/tex] = [tex]\frac{6}{5}[/tex]
The expression becomes;
[tex]\frac{1}{2} - \frac{6}{5}[/tex]
Find LCM
[tex]\frac{5-6}{10}[/tex]
Evaluate the resulting expression
[tex]\frac{5-12}{10}\\\\\frac{-7}{10}[/tex]
Hence the correct option is C i.e Negative StartFraction 7 over 10 EndFraction

Kim's softball team was playing in the championship game. When there were 4 innings left, the team was losing by a score of 17 to 6 points. In the last 4 innings, her team scored the same number of points per inning, and the other team did not score any more points. Kim's team won with the most points. Write an inequality to determine the number of points per inning, ppp, Kim's team could have scored. Write an inequality to determine the number of points per inning, ppp, Kim's team could have scor Find the minimum whole number of points per inning Kim's team could have scored.
Answer:
3
Step-by-step explanation:
Given the following :
Score when there were 4 innings left = 17 to 6
Kim's team = 6 ; opposition team = 17
Opposition didn't score any point in the last 4 innings
Kim's team scored same number of points per inning and also won with the most points
Minimum Number of points Kim's team could have scored per inning :
Let number of points scored in each of the last 4 innings = p
Since they also won eventually:
Then
4p + initial points > opposition point
4p + 6 > 17
4p > 17 - 6
4p > 11
p > 11/4
p > 2.75
Hence, the minimum number of points Kim's team could have scored per inning in the last 4 would be 3( nearest whole number)
