4/5 of the money collected from a fundraiser was divided equally among 8 grades
What fraction did each grade receive?
Answer:
1/10
Step-by-step explanation:
your equation is 4/5 divided by 8/1.
Lets solve that problem with the acronym KCF, or
Keep
Change
Flip.
K: "keep" the first fraction, or the one you are multiplying with, so 4/5 stays the same.
C: "change" the division sign to a multiplication sign, so 4/5x8/1
F: "flip" the second fraction, so 8/1 becomes 1/8.
now our equation is 4/5x1/8. If we solve that, we get 4/40, which reduced is 1/10.
Solve: 3x+4 2−6x = −2/ 5
Answer:
(3x + 4)/(2 - 6x) = -2/5
=>5(3x + 4) = -2(2 - 6x)
=> 15x + 20 = -4 + 12x
=> 15x -12x = -4 -20
=> 3x = -24
x = -24/3 = -8

a deposit of $2000 is invested in an account that earns 4.5% interest. how long until your balance reaches $3000? (assume simple interest) A= P(1+r)^t
A deposit of $2000 is invested in an account that earns 4.5% interest. The duration of time before the balance reaches $3000 is 9.2 years.
From the given information;
the principal deposited amount = 2000the annual interest rate = 4.5%the amount (A) estimated in t years = 3000The time required until your balance reaches the amount of 3000 can be estimated by using the given formula;
[tex]\mathbf{A = P ( 1+ r)^t}[/tex]
[tex]\mathbf{3000 = 2000 ( 1+ \dfrac{4.5}{100})^t}[/tex]
[tex]\mathbf{3000 = 2000 ( 1+ 0.045)^t}[/tex]
[tex]\mathbf{3000 = 2000 ( 1.045)^t}[/tex]
[tex]\mathbf{3 = 2( 1.045)^t}[/tex]
[tex]\mathbf{( 1.045)^t= \dfrac{3}{2}}[/tex]
[tex]\mathbf{( 1.045)^t= 1.5}[/tex]
[tex]\mathbf{( 1.045)^t= 1.5}[/tex]
t = 9.2 years
Therefore, we can conclude that the time duration (in years) until your balance reaches $3000 is 9.2.

What are the numbers?
Answer:
The numbers are (x,y)=(-5,8) or (8,-5)
Step-by-step explanation:
Let two numbers be x and y,
We have,
x+y=3
x=3-y---(i)
Now,
xy=-40
(3-y)y=-40 [From (i)]
3y-y^2=-40
y^2-3y-40=0
Factoring,
(y + 5) (y - 8)=0
Either,
y+5=0 or, y-8=0
y=-5 y=8

Answer:
Step-by-step explanation:
1)
We know that if [tex]x^2=9[/tex], then [tex]x=\pm \sqrt{9}[/tex], so [tex]\boxed{x=3,-3}[/tex]
2)
We know that if [tex]x^3=8[/tex], then [tex]x=\sqrt[3]{8}[/tex], so [tex]\boxed{x=2}[/tex]
3)
[tex]x^3=\frac{1}{8}[/tex] means that [tex]x=\sqrt[3]{\frac{1}{8}}=\frac{\sqrt[3]{1}}{\sqrt[3]{8}}=\frac{1}{2}[/tex].
So, [tex]\boxed{x=\frac{1}{2}}[/tex].
4)
[tex]x^3=27[/tex] means that [tex]x=\sqrt[3]{27}=\sqrt[3]{3^3}=3[/tex].
So, [tex]\boxed{x=3}[/tex].
5)
[tex]x^2=25[/tex] means that [tex]x=\pm \sqrt{25}=\pm \sqrt{5^2}=\pm 5[/tex].
So, [tex]x=5,-5[/tex].
6)
We know that the side length of the square will be [tex]\sqrt{\frac{9}{16}}=\frac{\sqrt{9}}{\sqrt{16}}=\boxed{\frac{3}{4}}[/tex].
7)
[tex]6x^2=54[/tex] means that [tex]x^2=9[/tex], which means that [tex]\boxed{x=3,-3}[/tex].
8)
[tex]2x^2+25=75[/tex] means that [tex]2x^2=50[/tex], which means that [tex]x^2=25[/tex], which means that [tex]\boxed{x=5,-5}[/tex]

m = y - y1
x - x1
m = 2 - 0
3 - 2
m = 2
y - y1 = m(x - x1)
y - 0 = 2(x - 2)
y = 2x - 4
f(x) = 2x - 4
g(x)
(2/3, 0) and (1, 2)
m = y - y1
x - x1
m = 2 - 0
1 - 2/3
m = 6
y - y1 = m(x - x1)
y - 2 = 6(x - 1)
y = 6x - 4
g(x) = 6x - 4
since both equations are linear that means the graphs will be straight lines with y-intercept being -4 for both of the graphs.
if,
g(x) = f(k*x)
f(x) = 2x - 4
f(k*x) = 2k*x - 4
6x - 4 = 2k*x - 4
6x = 2kx
6 = 2k
k = 3.

5x + 1 = 3x + 7
use the model to solve for X.
Answer:
X=3
Step-by-step explanation:
First you subtract 3x from both sides to keep x on one side.
5x minus 3x is 2x.
Then you subtract 1 from both sides to keep the variable alone.
7 minus 1 is 6.
Then you divided both sides by 2.
2x divided by 2 is x and 6 divided by 2 is three.
Then all you have left is x=3

what is the average hourly pay of someone making $45,000per year. Assuming wage growth of 5% a year, how much would he make the second year
Answer:
When it’s time for annual performance reviews, if you plan on including pay raises, you need to know the simple math behind calculating pay increases correctly. Raises can be based on any number of things including a worker’s piers, standard industry rates, length of time on the job, the amount of work to do, and even whether or not the boss likes the employee or not. There are few, if any, laws that govern how and when increases are granted, so it’s up to you to determine what you’re willing to give.
Answer:
See belowStep-by-step explanation:
Assume the person works 40 hours a week and 52 weeks a year.
The hourly pay would be:
$45000 ÷ (40*52) = $45000 ÷ 2080 =$21.63The yearly income the second year:
$45000 + 5% = $45000*1.05 = $47250edin has £300 in his saving account.
his bank offers him a fixed 5% simple interest rate per annum, for a period of 3 years.
how much interest will he have earned after 3 years?
Answer:
$45
Step-by-step explanation:
300/100 = $3 = 1%
$3 x 5 = $15 = 5%
$15 x 3 years = $45

Answer:
x = 41
y = 65
z = 107
Step-by-step explanation:
y and 65 are vertically opposite angles. Vertically opposite angles are equal.
y = 65
74 + y + x = 180
74 + 65 + x = 180
139 + x = 180
x = 180 - 139
x = 41
z is the exterior angle, whereas 66 and x are interior angles in a triangle.
Formula : -
Exterior angle = Sum of two interior angles
z = 66 + x
= 66 + 41
z = 107
The volume of this sphere is 972 pi cubic inches. What is its radius?
A sphere.
Recall the formula Sphere Volume = four-thirds pi r cubed.
7 inches
9 inches
108 inches
324 inches
volume of a sphere = ⁴/₃ πr³
⇒ 972π in³ = ⁴/₃ πr³
729 in³ = r³
r = 9 in
∴ the radius of a sphere of volume 972π in³ is 9 inches.Answer:
9 inches
