Answer:
number of dimes is 8
number of quarters is 15
Step-by-step explanation:
let 'd' = number of dimes
let 'd+7' = number of quarters
.10d + .25(d + 7) = 4.55
.10d + .25d + 1.75 = 4.55
.35d = 2.80
d = 8
q = 7 + 8
how many times does 8 go into 70
8 goes into 70 exactly 8 times, with a remainder of 6.
When dividing 70 by 8, we follow these steps:
Divide the first digit of the dividend (7) by the divisor (8). In this case, 7 divided by 8 is 0 with a remainder of 7.
Bring down the next digit of the dividend (0) and divide it by the divisor (8). 0 divided by 8 is 0.
Since there are no more digits in the dividend, the division process is complete.
The quotient is the result of the division, which is 8. The remainder is the value left over after division, which is 6 in this case.
Therefore, 8 goes into 70 exactly 8 times, with a remainder of 6.

Answer:
A 1
Step-by-step explanation:
The cube containing 125 = 5³ blocks will have a edge dimension of 5 blocks. The perimeter of one square face will be 4 times the edge dimension of the face, so will be 4×5 blocks = 20 blocks.
If 20 blocks = 20 units, then the edge of one block is 1 unit. Its volume is 1 unit³, or 1.
The appropriate choice is (A) 1 unit³ for the block volume.
Javier bought four 8-ounces bottles of water for hiking trip. He drank 28 ounces. How many ounces of water are left?
Answer:
4 ounces are left
Step-by-step explanation:
8 x 4 = 32
32 - 28 = 4
4 ounces are left
I hope this helped and if it did I would appreciate it if you marked me Brainliest. Thank you and have a nice day!
Answer:
If there are 4 water bottles with 8 ounces in each, 4•8=32 total ounces. If he drinks 28 ounces, you would have to subtract 28 from 32 to get 4

Answer:
A. False; perpendicular lines have slopes that are the negative inverse of each other.
Step-by-step explanation:
It is true that parallel lines have the same slope. However, perpendicular lines have slopes that are opposite reciprocals (negative inverse of each other). So, the compound statement is FALSE.

A man has a garden measuring 40m by 24m. He wants to divide it equally into the minimum number of square plots
Complete question :
A man has a garden measuring 40m by 24m. He wants to divide it equally into the minimum number of square plots. what is the length of each square plot?
Answer:
8 m
Step-by-step explanation:
Given that :
Dimension of garden = 40m by 24m
Length of garden = 40m
Width of garden = 24m
To Obtain the length of each square plot if the garden is divided into minimum number of square plots ; we take the highest common factor of the dimension:
Length (40) = 1, 2, 4, 5, 8, 10, 20, 40
Width (24) = 1, 2, 3, 4, 6, 8, 12, 24
The highest common factor here is 8 ;
Thus, the length of each square plot is 8m
Abdul ordered some books online and spent a total of $133. Each book cost $8 and he paid a total of $5 for shipping. How many books did he buy?
Answer:
8x+5=133
8x=128
x=16
Step-by-step explanation:
16 books
Answer:
He bought 16 books
Step-by-step explanation:
cost = flat fee + books * cost per book
133 = 5 +b*8 where b is the number of books
133 = 5+8b
Subtract 5 from each side
128 = 8b
Divide each side by 8
128/8 = 8b/8
16 = b
He bought 16 books
Oscar and Carla deposit $1,000.00 into a savings account which earns 10% interest compounded annually. They want to use the money in the account to go on a trip in 2 years. How much will they be able to spend?
Answer:
They will be able to spend $1210
Step-by-step explanation:
At the start, there will be $1000 in the savings account that will earn 10% of the current savings(1000) so 1000*(10/100)=$100 so after 1 year in the savings account there will be $1100 the same procces will happen for the next year
2nd year:1100*(10/100)=$110
total=$1100 + $110=$1210

Answer:
As below
Step-by-step explanation:
using eq from problem 4) y = -45x + 1080
then use the point slope formula with the slope of the above line at -45 and plug in your given point of (8, 240)
y-y1 = m(x-x1) where m is the slope above
y-240 = -45 (x - 8 ) this is an equation for the line but the teacher probably wants the slope intercept form... the formula is y = mx + b
soooo...
y-240 = -45x + 360
y = -45x +360 + 280
y = -45x + 640
there you go :)

Answer:

h(0) = 9
h(5) = -1
General Formulas and Concepts:
Pre-Algebra
Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightStep-by-step explanation:
Step 1: Define
h(x) = -2x + 9
x = -2
x = 0
x = 5
Step 2: Evaluate
x = -2
Substitute in x: h(-2) = -2(-2) + 9Multiply: h(-2) = 4 + 9Add: h(-2) = 13x = 0
Substitute in x: h(0) = -2(0) + 9Multiply: h(0) = 0 + 9Add: h(0) = 9x = 5
Substitute in x: h(5) = -2(5) + 9Multiply: h(5) = -10 + 9Add: h(5) = -1Ms. Aniston asked seven students in her class to collect pet food cans for a local animal shelter. The dot plot shows the number of food cans collected by each student. Each dot represents one student. What is the median of the data set? A. 9 B. 7 C. 6 D. 8
Answer: answer is C 7
Step-by-step explanation:
So for this problem it is important to know what a median is. The median is essentially the center number when everything is written out. So you want to take your line plot and write out each number on the bottom as many times as a dot appears above it. For this problem that would look like 6, 6, 7, 7, 8, 9, 9. Since you have seven numbers the center would be the 4th one. In ascending order out of these numbers the 7 occurs fourth thus giving you your answer.
The sum of three numbers is 4. The second number is 1 more than twice the first. The sum of the first and third is –1. Find the numbers.
1. The first number is equal to 2.
2. The second number is equal to 5.
3. The third number is equal to -3.
Let the first number be a.Let the second number be b.Let the third number be c.Translating the word sentence into an algebraic expression, we have;
The sum of three numbers is 4:
[tex]a+b+c=4[/tex] ....equation 1.
The second number is 1 more than twice the first:
[tex]b=2a+1[/tex] ....equation 2.
The sum of the first and third is –1:
[tex]a+c=-1[/tex] ....equation 3.
From eqn. 3, we have:
[tex]c=-1-a[/tex] ....equation 4.
Substituting into eqn. 1, we have:
[tex]a+2a+1+(-1-a)=4\\\\3a+ 1-1-a=4\\\\2a=4\\\\a=\frac{4}{2}[/tex]
a = 2
To find the value of b:
[tex]b=2a+1\\\\b=2(2)+1\\\\b=4+1[/tex]

Answer:
5
General Formulas and Concepts:

Order of Operations: BPEMDAS
Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to RightEquality Properties
Step-by-step explanation:
Step 1: Define Inequality
8x - 6 > 12 + 2x
Step 2: Solve for x
Subtract 2x on both sides: 6x - 6 > 12Add 6 on both sides: 6x > 18Divide 6 on both sides: x > 3Here we see that any value x greater than 3 would work as a solution to the inequality.

A box of cereal states that there are 75 calories in a three fourths 3/4-cup serving. What is the unit rate for calories per cup? How many calories are there in 2 cups of the cereal?
Answer:
a) The unit rate for calories per cup is 100 calories per cup
b) 200 calories in 2 cups of cereal.
Step-by-step explanation:
A box of cereal states that there are 75 calories in a three fourths 3/4-cup serving.
a) What is the unit rate for calories per cup?
This is calculated as:
3/4 cup = 75 calories
1 cup = x
Cross Multiply
3/4x = 75 calories × 1
x = 75 calories /3/4 cup
x = 75 ÷ 3/4
x = 75 × 4/3
x = 100 calories per cup
The unit rate for calories per cup is 100 calories per cup
b) How many calories are there in 2 cups of the cereal?
From the above question
3/4 cup = 75 calories
2 cups = x
Cross Multiply
3/4x = 75× 2
x = 150 ÷ 3/4
x = 150 × 4/3
x = 200 calories
There are 200 calories in 2 cups of cereal.
Jack usually mows his lawn in 3 hours. Marilyn can mow the same yard in 6 hours. How much time would it take for them to mow the lawn together?
Step-by-step explanation:
Jack mows 1 lawn in 3 hours
= 1/3 lawn in 1 hour
Marilyn mows 1 lawn in 6 hours
= 1/6 lawn in 1 hour
Together, they can mow 1/3 + 1/6
= 1/2 lawn in 1 hour.
Hence they will need 2 hours to mow the lawn.
