Step-by-step explanation:
.Ray's Rental Car Company charges a $50 rental fee, $15 for gas and $0.25 per mile driven. For the same car, Rosie's Rental Car Company charges $40
for rental and gas and $0.35 per mile driven. At what mile do the companies charge the same amount?
Answer: 166.667 miles
Step-by-step explanation:
For the first company, the cost can represented by the equation: y=0.25m +50+15
Which is the same as y=0.25m +65
For the second company, the cost can represented by the equation:0.35m+40
m is the miles driven
To find at after how many miles they cost the same, I will set both equations equal to each other to solve for m
0.25m+65=0.35m+40
-0.25m -0.25m
65=0.15m+40
-40 -40
25=0.15m. Divide both sides by 0.15
166.667=m
So after 166.667 miles, the companies charge the same.
You can also round it again: 166.67 or 166.7 or 167
Triangle A has side lengths 2, 3, and 4. Triangle B has side lengths 4, 5, and 6. Is Triangle A similar to Triangle B?
Answer:

1+1+1+1+1000+8364+20484923743 - 24762837763
-4,277,904,652 would be the correct answer
Only 5,7,9 and 11.
d(x) = |x| – 4

5|2x - 3| + 4 = 9
How do you solve this
Answer:
x = 2, or x = -1
Step-by-step explanation:
If 2x - 3 is inside the parenthesis (), then the value of x is 2.
If 2x - 3 is inside the absolute value sign, then the value of x will probably be -1.
Solution 1
(10x-15) + 4 = 9
10x -11 = 9
10x = 20 -> x = 2
Solution 2 (Not 100% sure)
|10x -15| +4 = 9
10x + 15 +4 = 9
10x + 19 = 9
10x = -10 -> x = -1
Please correct me if I'm wrong.

Step-by-step explanation:
A company rents out 17 food booths and 21 game booths at the county fair. The fee for a food booth is $75 plus $10 per day. The fee for a game booth is $95 plus $4 per day. The fair lasts for d days, and all the booths are rented for the entire time. Enter a simplified expression for the amount, in dollars, that the company is paid.
Answer:
Food booth= (75+10d)17
Game booth= (95+4d)21
Step-by-step explanation:
GAME BOOTH
$95 initial fee plus $4 per d amount of days
f(x)=95+4d
Multiply the expression by 21 because you have 21 game booths
FOOD BOOTH
$75 initial fee plus $10 per d amount of days
f(z)=75+10d)
multiply this expression by 17 because their are 17 food booths
hopefully this helps:)
Which one should I choose
Answer:
x<10
Step-by-step explanation:
1. Square of a Binomial
Symbols/Pattern:
(a + b)2 = a2 + 2ab + b2
(a - b)2 = 22 - 2ab + b2
In the pattern, if a is the first term and b is the last term, then the square
of a binomial consists of:
a) the square of the first term (a);
b) twice the product of the first and last terms (2ab); and
c) the square of the last term (54).
2. The product of the sum and difference of two terms

Step-by-step explanation:
A square has a diagonal that measures 18 inches. To the nearest tenth, what is the length of one side
of the square?
Answer:
18/sqrt(2)
Step-by-step explanation:
Divide the square into two congruent right triangles:
a and b are the sides of the triangle
since we know that a=b
then the right triangle is isosceles
meaning that the theorem of the 45-45-90 triangle is applicable
so then we can say that 18/sqrt(2) = a = b

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.
