Mike is on vacation and decides to rent a bike for part of the week. The rental cost is represented by the function c(d) = 25+20d, where is the number of days of use and c(d) is the total cost for d days of use. How much does the bike cost Mike if he uses it for 4 days?
Answer:
Cost for 4 days is 105
Step-by-step explanation:
To get the cost for 4 days, we simply substitute 4 for the value of d in the equation
Thus, we have
c(4) = 25 + 4(20)
C(4) = 25 + 80
C(4) = 105

Use divisibility rules to determine whether the number is divisible by 2, 3, 4, 5, 6, 8, 9, and 10.

2. 1515
3. 1071
Answer:
Divisibility Rules: 2, 3, 4, 5, 6, 9, and 10
A number aa is divisible by the number bb if a \div ba÷b has a remainder of zero (00). For example, 15 divided by 3 is exactly 5 which implies that its remainder is zero. We then say that 15 is divisible by 3.
In our other lesson, we discussed the divisibility rules for 7, 11, and 12. This time, we will cover the divisibility rules or tests for 2, 3, 4, 5, 6, 9, and 10. Believe me, you will be able to learn them very quickly because you may not know that you already have a basic and intuitive understanding of it. For instance, it is obvious that all even numbers are divisible by 2. That is pretty much the divisibility rule for 2. The goal of this divisibility rules lesson is to formalize what you already know.
3. 1071
Step-by-step explanation:
A number is divisible by 3 if the sum of its digits is divisible by 3. A number is divisible by 9 if the sum of its digits is divisible by 9. And a number is divisible by 6 if it is divisible by 2 (even number) and by 3.

5 more than the product of 6 and a number 23. What is the number?
Answer:
x = 3
Step-by-step explanation:
Let x be the number
Write it out as an equation: 6x + 5 = 23Subtract 5 from each side, so it now looks like this: 6x = 18Divide each side by 6 to cancel out the 6 next to x. It should now look like this: x = 3

Explain how to use multiplication to find the value of 1/3 divided by 9/5 Use the words
multiplication, divisor, quotient, and reciprocal in your explanation
Answer:
[tex] \frac{1}{3} \div \frac{9}{5} = \frac{5}{27} [/tex]
Step-by-step explanation:
[tex] \\ \frac{1}{3} \div \frac{9}{5} \\ \\ \frac{1}{3} \times \frac{5}{9} \\ \\ \frac{5}{27} \\ \\ to \: get \: the \: quotient \: of \: the \: division \\ between \: \frac{1}{3} \: and \: \frac{9}{5} \: \\ the \: reciprocal \: of \: the \: divisor \: \: \frac{9}{5}, \\ is \: taken \: as \: the \: division \: sign \: is \: turned \\ \: to \: a \: mutiplication \: sign.\\ [/tex]
Answer: 5/27
First, we have to get the quotient. So, we divide.
[tex]\frac{1}{3}[/tex] ÷ [tex]\frac{9}{5}[/tex]
The reciprocal of [tex]\frac{9}{5}[/tex] will be turned into a multiplication sign.
[tex]\frac{1}{3}[/tex] × [tex]\frac{9}{5}[/tex] = [tex]\frac{5}{27}[/tex]

The sum of two consecutive integers is at most 223.
What is the larger of the two integers?
Answer:
Divide 223 by 2: 223/2 = 111.5
Then fix one number to 111.5 - 0.5 ann the other to 111.5 + 0.5
The two numbers are 111 and 112.
Then the answer is 112.

Hernando ate StartFraction 2 Over 8 EndFraction of a pizza for a dinner. He gave his 6 friends the rest of the pizza and told them to share it equally. To determine the fraction of the whole pizza that each of his friends received, Hernando performed the calculations below. StartFraction 6 Over 8 EndFraction divided by 6 = StartFraction (6 divided by 6) Over 8 EndFraction = one-eighth He concluded that each person received One-eighth of the whole pizza. Are Hernando's calculations correct? Explain why or why not. Yes, they are correct. Hernando divided 6 by 6. Yes, they are correct. Hernando divided Two-eighths by 6. No, they are not correct. Hernando should have multiplied by 6, not divided by 6. No, they are not correct. Hernando should have divided 8 by 6, not 6 by 6.
Answer:
Step-by-step explanation:
Hernando = 2/8
His 6 friends = 6/8
Total pizza = 2/8 + 6/8
= 8/8
Hernando's calculation
6/8 ÷ 6
= (6÷6) / 8
= 1/8
Correct calculation
6/8 ÷ 6
= 6 / 8 × 1/6
= (6 × 1) / (8*6)
= 6/48
= 1/8.
Therefore, Yes, they are correct. Hernando divided 6 by 6.
Answer:
The correct answer is A

-0.64x+0.44x=5.8 solve for x
Answer:
x=-29
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
−0.64x+0.44x=5.8
(−0.64x+0.44x)=5.8(Combine Like Terms)
−0.2x=5.8
−0.2x=5.8
Step 2: Divide both sides by -0.2.
-0.2x/-0.2=5.8/-0.2
x=-29

A recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B. You use 3 cups of ingredient A. How many cups of ingredient B do you need?
Answer:
8.4cups
Step-by-step explanation:
Given:
recipe calls for 1/2 cup of ingredient A for every 1 2/5 cups of ingredient B.
By using the ratio of both ingredients
Let X= amount of ingredient A in cups
Let Y= amount of ingredient B in cups
We can interpret like this
(X/Y) = (1/2 cup)/(1 2/5 cups)
1 2/5 cups = 7/5 cups
(X/Y) = (1/2)/(7/5)
(7/5)X= (1/2)Y
We can find the value of Y
Y= 2*(7/5)X
Y = (14/5)X
You use 3 cups of ingredient A. Then X= 3cups, then Y=
Y = (14/5)× 3
Y=8.4cups
There are 8.4cups cups of ingredient B do you needed
A truck can be rented from Company A for $130 a day plus $0.60 per mile. Company B charges $70 a day plus $0.90 per mile to rent the same truck. Find the number of miles in a day at which the rental costs for Company A and Company B are the same.
Answer:
200 miles
Step-by-step explanation:
Let's say that our variable is x, where x equals the amount of miles
Company A: a(x)=0.6x+130
Company B: b(x)=0.9x+70
For the first equation, you are charged 130 dollars, in addition to the 0.60 cents that you are charged per mile.
For the second equation, you are charged 70 dollars, in addition to the 0.90 cents that you are charged per mile.
You want to find how many miles it takes to make the two equations equal:
0.6x+130 = 0.9x+70 (Set them equal to each other because you are trying to find when the miles are equal and the cost is equal)
130=0.3x+70 (Subtract 0.6x from both sides)
60=0.3x (Subtract 70 from both sides)
x=200 (Divide both sides by 0.3 to find x)
Remember that x is the amount of miles, so, Company A and B would charge the same if you drove 200 miles.
Answer:I believe it’s 200 miles
Step-by-step explanation: let x represent the mileage you are trying to find and set the two equations equal to one another to find the mileage and which the rental cost would be the same.
130 + 0.60x = 70 + 0.90x
130-70 = 0.90x - 0.60x
60 = 0.30x
X= 60/0.03
X= 200 miles
