One year, the population of a city was 330,000. Several years later it was
270,600. Find the percent decrease.
HELP ASAP
Answer:
18%
Step-by-step explanation:
Express the ending population as a percentage of the starting population:
270000 divided by 330000=0.82
0.82 *100=82
subtract from the 100% we started with to get the percent decrease:
100% - 82% = 18

Meldrick had $28 in his savings account. On Monday, he deposited his earnings from mowing lawns on the weekend. He earned the same amount the next weekend but deposited only 40% of those earnings. After making the two deposits, he had $70 in his account. How much did he earn in one weekend?
Answer:
70 - 28 = 42
42/100 X 40 = 16.8
42 - 16.8 = 25.20

Hi another math question please help:)
Answer:
1). Yes
2). Yes
3). No
Step-by-step explanation:
1). y = 3
We can rewrite this equation in the slope-intercept form as,
y = 0.x + 3
Here, slope = 0
y-intercept = 3
Therefore, it's a linear relation.
YES.
2). 2x - 5y = 10
5y = 2x - 10
y = [tex]\frac{2}{5}x-2[/tex]
Therefor, it's a linear function.
YES
3). y = x(x + 3)
y =x² + 3x
Since, this equation is a quadratic equation,
It's not a linear function.
NO

Write the slope-intercept form of the equation with the given characteristics: Slope: 3/2 Point: (-4,7)
Answer:
[tex]y = \frac{3}{2} x + 13[/tex]
Step-by-step explanation:
1) Use point-slope formula [tex]y-y_1 = m (x-x_1)[/tex] to find the slope-intercept form (or y = mx + b form) of the equation. m represents the slope, and [tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of a point the line intersects. So, substitute [tex]\frac{3}{2}[/tex] for m, -4 for [tex]x_1[/tex], and 7 for [tex]y_1[/tex]. Then, simplify and isolate y on the left side like so:
[tex]y-(7) = \frac{3}{2} (x - (-4)) \\y -7 = \frac{3}{2} (x + 4) \\y - 7 = \frac{3}{2} x + 6\\y = \frac{3}{2} x + 13[/tex]
A snail moves at the rate of 1/8 inch per minute. How many minutes does it take the snail to move 1 1/3 inches?
Answer:
It should be 10 2/3 minutes
Step-by-step explanation:
You divide 1 1/3 by 1/8 and you get 10 2/3 minutes. So it takes the snail 10 2/3 or 10.66 minutes to move 1 1/3 inches

Calculate the value of x in the given figure
Answer:
the value of x is 25 degrees
Step-by-step explanation:
Here, we want to get the value of x
we use an important triangle angular principle here
And the principle is that when we add two opposite interior angles, we get the value of the exterior angle on the third side
Thus, mathematically;
x + 75 = 4x
4x-x = 75
3x = 75
x = 75/3
x = 25 degrees

Answer:
[tex]12x\leq 24[/tex]; [tex]x\leq 2[/tex]
Step-by-step explanation:
So you have 12 math problems that each take x amount of minutes, and have 24 minutes to finish them. Remember, you can't exceed the 24 minutes (but you are allowed to equal that time). So:
[tex]12x\leq 24[/tex]
Then you can simplify by dividing both sides by 2:
[tex]x\leq 2[/tex]
Find the value of x
Step-by-step explanation:
By Exterior Angle Theorem, the sum of the 2 inner angles of the triangle is equal to the exterior angle by a straight line.
Therefore we have x + 72° = 90° + 34°.
=> x + 72° = 124°, x = 52°.
Hence the value of x is 52°.

[tex]2 { }^{2} + 2 \times {2}^{2} [/tex]
Answer:
1. 2268.
2. 12.
Step-by-step explanation:
1. Given the mathematical expression; 2 * 2 * 9 * 7 * 9
We would simplify the expression;
2 * 2 * 9 * 7 * 9 = 4 * 81 * 7
2 * 2 * 9 * 7 * 9 = 28 * 81
2 * 2 * 9 * 7 * 9 = 2268
2. Given the mathematical expression; 2² + 2 * 2²
From BODMAS (Bracket Of Division Multiplication Addition Substraction), we would first of all multiply before performing an addition operation.
Therefore,
2² + 2 * 2² = 4 + 2 * 4
2² + 2 * 2² = 4 + 8
2² + 2 * 2² = 12
Answer:
1. 2268 2. 12

How many people work in the factory? When- 800 people live in the town. 15 out of every 50 adults work in the factory. The town has 200 children aged 17 or younger. 18 is considered the age for being called an adult. Children under 18 may not work in the factory.
Answer: 180 people
Step-by-step explanation:
Number if people living in the town = 800
Children aged 17 or younger = 200
Adults of 18 and above = 800 - 200 = 600
Since 15 out of every 50 adults work in the factory, the number of people that work in the factory will be:
= 15/50 × 600
= 180 people
Hi! during this pandemic it's kind of hard to learn math over the screen. no one is willing to help since my teachers are busy and my mom is confused. I Don't have friends to go to who could help me..So i'm hoping someone here could help! ...!!i cropped it so you could see better..Thanks!
Answer:
a) c=33.5
I'll try my best to explain and help you out here! online school sucks, I hope you get the hang of it soon!
Step-by-step explanation:
Simplify both sides of the equation.
c(5)=(35.5)(5)−10
5c=177.5+−10
5c=(177.5 + −10) (Combine Like Terms)
5c=167.5
Divide both sides by 5.
5c/5 = 167.5/5
c=33.5

can someone help on these two thanks
Answer:
C & D
Step-by-step explanation:
For the first one, all you have to do is count how many numbers are behind the decimal point and add them together (1 + 3 = 4) and then you count up the decimal 4 places which would be 0.7416.
For the second one, you divide the days by miles (18/3=6) then you divide the 6 by 72 which would be 12.
Hope this helps!

No, 5/8 cannot make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex] to be true
The given fractional equation is:
[tex]\frac{8}{15}-x=\frac{3}{7}[/tex]
To calculate the fraction that will make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex], solve for x in the given equation:
[tex]\frac{8}{15}-x=\frac{3}{7}[/tex]
Collect like terms
[tex]x=\frac{8}{15}-\frac{3}{7}[/tex]
Simplify the resulting fraction as follows:
[tex]x=\frac{56-45}{105} \\\\x=\frac{11}{105}[/tex]
Therefore, the missing fraction that will make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex] true is 11/05
We can conclude that 5/8 cannot make the equation [tex]\frac{8}{15}-x=\frac{3}{7}[/tex] to be true

Since [tex]\frac{5}{8} \neq\frac{11}{105}[/tex], hence [tex]\frac{5}{8}[/tex] will not make the equation true.
Equations and expression
Given the equation
[tex]\frac{8}{15}-a=\frac{3}{7}[/tex]a is the fraction that will make the equation to be equal
Subtract [tex]\frac{8}{15}[/tex] from both sides;
[tex]\frac{8}{15}-a-\frac{8}{15} =\frac{3}{7}-\frac{8}{15}\\-a= \frac{3}{7}-\frac{8}{15}\\-a=\frac{3(15)-7(8)}{105} \\-a=\frac{45-56}{105}\\-a=\frac{-11}{105}[/tex]
Multiply both sides by a negative sign to have:
[tex]-(-a)=-(-\frac{11}{105} )\\a=\frac{11}{105}[/tex]
Since [tex]\frac{5}{8} \neq\frac{11}{105}[/tex], hence [tex]\frac{5}{8}[/tex] will not make the equation true.

3x+2y=46 x+y=17 how u solve
Answer: (12, 5)
Step-by-step explanation:
3x + 2y = 46 x + y = 17
Subtract y from both sides of the equation.
x = 17 − y 3x + 2y = 46
Replace all occurrences of x with 17 − y in each equation.
51 − y = 46
x = 17 − y
Solve for y in the first equation.
Move all terms not containing y to the right side of the equation.
Subtract 51 from both sides of the equation.
−y = 46 − 51
x = 17 − y
Subtract 51 from 46.
−y = −5
x = 17 − y
Multiply each term in −y = −5 by −1
Multiply each term in −y = −5 by −1. (−y) ⋅ −1 = (−5) ⋅ −1
x = 17 − y
Multiply (−y) ⋅ −1.
y = (−5) ⋅ −1
x = 17 − y
Multiply −5 by −1.
y = 5
x = 17 − y
Replace all occurrences of y with 5 in each equation.
Replace all occurrences of y in x = 17 − y with 5. x = 17 − (5)
y = 5
Simplify 17 − (5).
Multiply −1 by 5.
x = 17 − 5
y = 5
Subtract 5 from 17.
x = 12
y = 5
The solution to the system is the complete set of ordered pairs that are valid solutions.

Sammie read at the rate of 25 pages per hour. Alex read at the rate of 1/2 of a pages per minute. Who was reading faster? By how many pages per hour faster?
Answer:
Alex is reading faster by 5 more pages per hour.
Step-by-step explanation:
Alex's rate of reading is 1/2 pages per minute, or 1 page every 2 minutes. To convert his rate to pages per hour, we can divide 60 (minutes in an hour) by 2 (minutes it takes Alex to read a page) which is equal to 30 (pages read in an hour). Therefore, Alex is reading at 30 pages an hour and reading 5 more pages an hour than Sammie.
