1) Mrs.Galicia sells online math and reading games. His revenue for each game (in dollars) is modeled by the given equations, where x is the number of days since the games went on sale.
Math Game: M(d)=x^2-9x-10
Reading Game: R(d)=2x+10
Solve the system algebraically. After how many days is the revenue for each game the same? Show your work and explain your answer.
Step-by-step explanation:
Given the following expression;
Math Game: M(d)=x^2-9x-10
Reading Game: R(d)=2x+10
x is the number of days since the games went on sale
In order to determine after how many days the revenue for each game wil be the same, we will equate M(d) to R(d)
M(d) = R(d)
x^2-9x-10 = 2x+10
x^2-9x-10 -2x-10 = 0
x^2-11x-20 = 0
factorize
x = 11±√121-4(-20)/2
x = 11±√121+80/2
x = 11±√201/2
x = 11±37.16/2
x = 11+37.16/2
x = 48.16/2
x = 24.06
Hence the revenue for each game will be the same after 24 days
It takes about 13 days for the revenue for each game the same.
Revenue is the amount of money made from selling a particular amount of products.
Given that the revenue is given by:
Math Game: M(d)=x²-9x-10
Reading Game: R(d)=2x+10
For both games to have the same revenue, hence:
M(d) = R(d)
x² - 9x - 10 = 2x + 10
x² - 11x - 20 = 0
x = -1.6 or x = 12.6
Since the number of days cannot be negative, hence it takes about 13 days for the revenue for each game the same.

Can someone please explain how they got 12??
Answer:
They got 12 by multiplying 3 × 4
Step-by-step explanation:
They used distributive property to multiply the 3 by each number in the parentheses
3 × x/3 = 1x = x
3 × 4 = 12
x + 12 = 6 × 3
They mutliplied 6 × 3 to get 18
x + 12 = 18
They then subtracted both sides by 12 to isolate the variable
x + 12 - 12 = 18 - 12
x = 6
Answer:
hope this helps! lmk if you still dont understand it!
:)
Step-by-step explanation:
you do 3*4 which gives you 12 and 3*x/3, but you should keep it as x
6*3 is 18
x+12=18 (solve for x)
-12=-12
x=6
check the answer:
3*(6/3+4)=6*3
3(2+4)=6*3
6+12=6*3
18=18
find cube root of 175616 ??
i will mark u as brainlist if u would give a correct answer with Explanation
Answer:
56
Step-by-step explanation:
Cube root of 175616 by prime factorization method is 56
Solution:
To find cube root of 175616 by prime factorization method
A number that must be multiplied by itself three times to equal a given number is called cube root
Prime factorization method:
Prime factorization is a number written as the product of all its prime factors.
In order of finding cube root by prime factorization we use the following steps:
Step I : Obtain the given number
Step II : Resolve it into prime factors.
Step III : Group the factors in 3 in such a way that each number of the group is same
Step IV : Take one factor from each group
Step V : Find the product of the factors obtained in step IV. This product is the required cube root
Prime factorization of 175616:
\text{ prime factors of 175616 } = 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 7 \times 7 \times 7 prime factors of 175616 =2×2×2×2×2×2×2×2×2×7×7×7
Thus we get,
\sqrt[3]{175616} = \sqrt[3]{2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 2 \times 7 \times 7 \times 7}

Answer:
d = 0
Step-by-step explanation:
cancel equal terms on both sides of the equation
= 8d = 6d
move variable to the left and change its sign
8d - 6d = 0
2d = 0
divide both sides of the equation by 2
d = 0
Answer:
d = 0
Step-by-step explanation:
-7 and -7 cancel out
8d = 6d
collect like terms 8d - 6d
8d-6d=0
2d = 0
divide both sides

2) Suppose 120 people are surveyed and asked about their eating habits. 50 people
stated that they like Raising Cane's chicken fingers, 80 people said that they like
Layne's chicken fingers. If 10 people don't like either, then...
a) What is the probability that someone surveyed likes both Raising Cane's and
Layne's chicken fingers?
Answer:
1/6
Step-by-step explanation:
Given that :
Total surveyed (u) = 120
n(Cane's chicken fingers) = 50
n(Layne's chicken fingers) = 80
n(do not like either) = 10
a)
What is the probability that someone surveyed likes both Raising Cane's and Layne's chicken fingers?
n(Cane's n Layne's) = 20
u = 120
P = required outcome / total possible outcomes
P(Layne's and Cane's chicken) = [n(Cane's n Layne's)/ u]
= 20 / 120
= 1/6

A bakery sold 145 chocolate cupcakes in a day, which was 29% of the total number of cupcakes sold that day. How many total cupcakes did the bakery sell that day?
Answer:
500 cupcakes
Step-by-step explanation:
Given that the 145 cupcakes is 29% of the total number of cupcakes sold that day,
29% --- 145 cupcakes
The total number of cupcakes sold would be 100%.
1% --- 145 ÷29= 5 cupcakes
100% --- 100(5)= 500 cupcakes
Thus, the bakery sold 500 cupcakes that day.

Bernardo is saving up money to pay off a debt. His father loaned him $90 and is charging him $1 interest each day. Bernardo earns $20 a day mowing lawns. He only wants to use half of his daily earnings to pay off his debt. How many days will it take io so eliminate what the son owes his father.
Answer:
It will take 10 days
Step-by-step explanation:
Here, we want to know the number of days it will take for Bernardo to clear the debt he owes his father.
We proceed as follows;
Let the number of days be x
So after x days, there will be an interest of x * 1 = $90
So the amount of money he owes his father after x days will be $(90 + x)
After x days, the amount he would have earned from mowing lawns will be x * 20 = $20x
He intend using half of this to clear the loan
Half of this is 20x/2 = $10x
We know that this amount is enough to clear the loan, so we equate this value to the amount he wants to use to clear the loan
So;
90 + x = 10x
90 = 10x - x
9x = 90
x = 90/9
x = 10

4) The line shown represents the amount of money
left on a gift card, y, after Mina buys lattes. After
buying 2 lattes, she has $2 left. What is an
equation of the line in point-slope form?
Answer:
[tex] y - 2 = -3(x - 2) [/tex]
Step-by-step explanation:
The equation of the line in point-slope form is given by the formula, [tex] y - b = m(x - a) [/tex], where,
(a, b) = coordinates of a point on the line.
[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} [/tex]
Given that after buying 2 lattes, she has $2 left, this represents a point on the line which is (a, b) = (2, 2). That is, when x = 2 lattes, y = $2.
Let's find the slope using the point (2, 2) and any other point on the line, say at x = 1, when y = 5, that's (1, 5).
[tex] m = slope = \frac{y_2 - y_1}{x_2 - x_1} = \frac{5 - 2}{1 - 2} [/tex]
[tex] = \frac{3}{-1} [/tex]
[tex] m = slope = -3 [/tex]
Plug m = -3, a = 2, and b = 2 into point-slope form.
[tex] y - b = m(x - a) [/tex]
[tex] y - 2 = -3(x - 2) [/tex]
Can anyone solve this for me :))?
Answer:
x = 32°
y = 17°
Step-by-step explanation:
Let's look at the bottom triangle since it has two angles.
62° + 75° = 137°
180° - 137° = 43°
The missing angle measure is 43°. Since the two angles make up a straight line,
(4x + 9)° + 43° = 180
4x + 52° = 180°
4x = 128°
x = 32°
The angle measuring 62° is a vertical angle so the angle opposite it is also 62°. The missing angle for that triangle would 40° because 180° - 140° = 40°.
62° + 40° = 102°
180° - 102° = 78°
(5y - 7)° = 78°
5y = 85°
y = 17°
Hope that helps.
