in kick boxing, it is found that the force needed to break a board varies inversely with the length of the board. If it takes 5 lbs. of pressure to break a board 2 feet long, how many pounds of pressure will it take to break a board that is 8 feet long
Answers
Answer:
20
Step-by-step explanation:
Since we know that it takes 5lbs. to break a 2-foot longboard, we first want to figure out how many pounds it takes to break a 1foot board.
5/2=2.5
It takes 2.5 lbs to break a 1-foot board.
2.5x8=20
It would take 20lbs to break an 8-foot longboard.
Hope this helps :)
Find what the x is.
45= 5/7x
Answers
Answer:
x = 63
Step-by-step explanation:
Step 1: Multiply both sides by 7/5.
[tex]45 *\frac{7}{5}=\frac{5}{7}x*\frac{7}{5}[/tex] [tex]63 = x[/tex]Step 2: Check if solution is correct.
[tex]45 = \frac{5}{7}(63)[/tex] [tex]45 = 5 * 9[/tex] [tex]45 = 45[/tex]Therefore, x = 63.
x = 63
Step-by-step explanation:45 = 5/7x
=> 9 = x/7
=> x = 63.

Answers
The reason to that is because you have to subtract 20 from 4 then multiple 16 by 4
To work out 20 + 5(3) you would multiply 5 and 3 first and then add the 20 to get a value of 35. Can you start at 35 and reverse those two steps to get back to 3? Explain the two steps you would take to do that.
Answers
Answer:
35-25= 15/5= 3

First you subtract 25 from 35 then you divide 15 by 3.

A textbook company sells teacher editions

Each package includes 3 teacher editions
for every 65 student editions. Which
combination could a school order?
A.
9 teacher to 260 student editions
B. 12 teacher to 325 student editions
12 teacher to 260 student editions
Answers
Answer:
C. 12 teacher editions and 260 student editions
Step-by-step explanation:
We can use division to solve this problem
65 ÷ 3 = 21.66... we can round this to 22 student ones we get 1 teacher copy.
A. 260 ÷ 9 = 28.99... we can round to 29 students ones we get 1 teacher copy so this one isn't correct.
B. 325 ÷ 12= 27.083... we can round to 27 students ones we get 1 teacher copy so this one isn't correct.
C. 260 ÷ 12 = 65 ÷ 3 = 21.66... we can round this to 22 student ones we get 1 teacher copy so this option is correct
C

Answers
Answer:
1 13/24
Step-by-step explanation:
First we need to find the LCD (lowest common Denominator) which will be 24. When we multiply 8 x 3 = 24 we will also multiply 5 by 3 which equals 15. So 5/8 = 15/24. Then we multiply 12 x 2 = 24, and again we also multiply the numerator by the same number which is 11 x 2 = 22. So 11/12 = 22/24.
Now that we have the LCD then we can add up the two. So 15/24 + 22/24 = 37/24. Now we need to simplify that to 1 13/24. Thank you.
Keith will run at most 26 miles this week. So far, he has run 14 miles. What are the possible numbers of additional miles he will run? Use t for the number of additional miles he will run. Write your answer as an inequality solved for t.
Answers
Answer:
[tex]t \leqslant 12[/tex]
Step-by-step explanation:
We know that Keith has ran 14 miles already, and he's aiming to reach no more than 26 miles, this week.
So we can put:
[tex]14 + t \leqslant 26[/tex]
Since, 14 is the number we know, t represents the number we have yet to find, and 26 is the product of this inequality. (We use the less-than-or-equal-to sign, because Keith is only aiming for 26 or less miles.)
Now we solve:
Subtract 14 on both sides to get
[tex]t \leqslant 12[/tex]
So t is less-than-or-equal-to 12, meaning Keith has 12 or less miles to run in order to reach 26 miles.
Hope this helps :)

Is 7.6 greater than, equal to, or less than 7.60
Answers
Answer:
Equal to
Step-by-step explanation:
It is found that 7.6 repeating is equal to 7.60
What is Algebra?Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.
The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.
The "=" sign and terms on both sides must always be present when writing an equation.
We are given the number 7.6 so we have to find whether the number is greater than, equal to, or less than 7.60
Therefore, we can see that 7.6 = 7.60
So they are equal to each other.

Step-by-step explanation:
So really, in this question, all you care about is the 10,000ths place
The 10,000ths place in this number is 8. Since 8 is greater that four, round up to 700,000
Answer:
700,000
Step-by-step explanation:
Round off all the numbers after the first number
If rounded off and the number closest to the first no is 5 and above, it automatically approximates the next number to its left.
Example: 681,858
The last no is 8, it therfeore approximates 5, thereby changing it to a 6
After being changed to a 6, it approximates the next no to its left, 8, turning it into a 9, nine approximates 1, turns it to a 2, two can't approximate, it's below 5, move on to 8, eight approximates 6 turning it to a 7, that's how I got my 700,000.

the serving size for a toddlers daily vitamin c is 3/4 cup of orange juice. if there are 2 1/4
cups of orange juice how many servings of vitamin c are there for a toddler
Answers
To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .
2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4
9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings
Answer:
Three servings
To find the number of servings we need to determine how many sets of 3/4 there are in 2 1/4 .
2 1/4 divided by 2 (4) + 1 = 1/4= 4/1 = 4 which will equal 9/4
9/4 divided by 3/4= 9/4 x 4/3 =9/3= 3 servings
