Olivia's cell phone bill last month was $125. This month her bill is $85. What is the percent of change in Olivia's bill?
Answer:
32%
Step-by-step explanation:
Olivia's cell phone bill last month was $125. This month her bill is $85. What is the percent of change in Olivia's bill?
The formula for Percent change =
Amount of change/Original amount × 100
Amount of change = Original amount = New amount
Original Amount/bill = $125
New amount/bill = $85
= $125 - $85
= $40
Percent change = $40/$125 × 100
Percent change = 0.32 × 100
Percent change = 32%
Therefore, the percent of change in Olivia's bill is 32%

At the beginning of the year, John had $40 in savings and saved an additional
$13 each week thereafter. Isaac started the year with $80 and saved $9 every
week. Let J represent the amount of money John has saved t weeks after the
beginning of the year and let I represent the amount of money Isaac has
saved t weeks after the beginning of the year. Write an equation for each
situation, in terms of t, and determine the number of weeks after the
beginning of the year until John and Isaac have the same amount of money
saved.
Answer:
J= 40+13t
I= 80+9t
they are equal at 10 weeks
Step-by-step explanation:
So we can start this by writing our equations
J= 40+13t
I=80+9t
To figure out when they're equal set the two equations equal to each other and solve for t
40+13t=80+9t
subtract 40 and 9t from both sides to get
40=4t
divide by 4 and get
t=10
Write an algebraic expression for "8 less than the product of 3 and j"
Answer: 3(j)-8
Step-by-step explanation: well first the product means multiplication, so u multiply 3 and j. and the second part is 8 less than that, so 8 is the last part so u do 3 times j minus 8. i graduated from high school last year so i know what im doin
According to the question,
Let,
The first number be "3".The second number be "j".The third number be "8".Now,
The product of "3" and "j" will be "3j" and the third number i.e., "8" less than the product.
Then the equation will be:
[tex]3j-8[/tex]Thus the above response is appropriate.

Solve for a.

Enter the number that goes

Enter
Answer that goes in the box = 28
===================================================
Explanation:
We have a white triangle shown as the empty space between the green squares.
This right triangle has the following sides:
a = unknown horizontal legb = 6 = vertical legc = 8 = hypotenuseUse the Pythagorean Theorem to solve for 'a'
a^2 + b^2 = c^2
a^2 + 6^2 = 8^2
a^2 + 36 = 64
a^2 = 64 - 36 ..... subtract 36 from both sides
a^2 = 28
a = sqrt(28) .... apply the square root to both sides
Optionally we can simplify like so
a = sqrt(28)
a = sqrt(4*7)
a = sqrt(4)*sqrt(7)
a = 2*sqrt(7)
But this would not fit the answer format your teacher has provided. So we'll stick to sqrt(28) as the final answer.

A salesperson at a jewelry store earns7% commission each week. Last week, jarrod sold 450$ worth of jewelry. How much did he make in commission? How much did the jewelry store make from his sales?
Answer:
he made $31.50 in commission
the jewelry store made $418.50
Step-by-step explanation:
turn the percent to a decimal by moving it 2 places 7%=.07
then multiply .07 by 450 to get his commission =31.50
then subtract 31.50 and 450 = 418.50
Mark jogged 3 and5/7 km. His sister jogged 2 and 4/5 km. How much farther did mark jog?
Answer: 32/35 km
Step-by-step explanation: First you have to find a common denominator between these two mixed numbers. That basically means that you have to convert them so that they both have the same denominator, that way they can be compared to one another. The easiest way to do this is to just multiply the denominators. 5 x 7 = 35. I will use 35 as my denominator. Then you multiply the numerators by the same number that you multiplied the denominator by to get 35. Since 7 x 5 = 35, 5 x 5 = 25. Same with the second fraction. 5 x 7 = 35. 4 x 7 = 28. The mixed numbers we have are now 3 and 25/35 and 2 28/35. To figure out how much farther Mark jogged we just take his distance, and subtract his sister's distance from it. 3 25/35 minus 2 28/35 = 32/35.

Evaluate the function expression
5•f(1)+5•g(9)=
Step-by-step explanation:
By getting our values from the graph,
When x = 1, the blue line has y-value -5.
When x = 9, the dotted line has y-value -6.
Hence,
f(1) + 5 * g(9) = (-5) + 5(-6) = -35.
Answer:
From the above graph,
→When x=1, y=f(1)=-5
→When x=9, y=g(x)=-6
• 5×f(1)+5×g(9)
=5{f(1)+g(9)}
=5{(-5)+(-6)}
=5(-11)
=-55
