how many times does 8 go into 70
Answers
Hope this helps
Ty
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. 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.
please visit my previous questions to know what the word problem is
Answers
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

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?
Answers
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.
A man has a garden measuring 40m by 24m. He wants to divide it equally into the minimum number of square plots
Answers
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

Ms. 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
Answers
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.
Answer: answer is C 7

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.
Answers
2nd condition: y = 2x + 1
3rd condition: x + z = - 1 <=> z = - x - 1
Based on the 2nd and 3rd, we replace the 1st as following:
x + 2x + 1 - x - 1 = 4 <=>
2x = 4 <=>
x = 2
Since x = 2, we solve the 2nd as following:
y = 2x + 1 <=>
y = 2*2 + 1 <=>
y = 4 + 1 <=>
y = 5
Same thing for the 3rd:
z = - x - 1 <=>
z = - 2 - 1 <=>
z = - 3
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:

Answers
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
