Answer:
For question 2/3 ÷ 1/4
Answer: 8/3 or 2 2/3
Step-by-step explanation:
Common denominator is 12
8/12 ÷ 3/12
Divide (Multiply by the reciprocal)
8/12 x 12/3
Answer is 8/3 or 2 2/3
4a: to divide fractions, you keep change flip. keep the 2/3, change the dividing sign to a multiplication sign, and flip 1/4 to 4/1. then multiply. 2 • 4 is 8, and 3 • 1 is 3. 8/3 is an improper fraction, since 8 is greater than 3. 8 can go into three 2 times, which is 6, and leaves 2 behind, making the answer 2 and 2/3.
4b: do the same process as 4a, keep change flip. keep 10/3, change the division to multiply, and flip 2/6 to 6/2. for this one, you can cross multiply. for example, across from 10 is 2. 2<10, so you would see how many times 2 can go into 10, which is 5 times. 2 can only go into 2 one time, so you change the two to a one. do the same thing with 6 and 3. 3<6, so 3 can go into 6 two times, so the six would turn into a 2. 3 can go into 3 one time, so change the 3 to a 1. multiply the new numbers. 5 x 2 is 10, and 1 x 1 is 1. your answer is 10/1 which can also be 10. answer is 10.
4c: same process. keep change flip. end up with 5/6 times 12/7. you can only cross multiply with 6 and 12, since 5 and 7 don’t have a common factor. so for 6 and 12, 6<12. 6 goes into 12 2 times so the 12 turns into a 2. 6 goes into 6 only once, so it turns into a one. multiply. 5 x 2 is 10, 1 x 7 is 7. 10/7 is an improper fraction, so u have to change it. 10 goes into 7 once and three is left. so the answer is 1 and 3/7.
4d: same process keep change flip. we have to change 2 and 3/4 into an improper fraction so it can be easier to multiply. 2 x 4 is 8, and 8 + 3 is 11, so it would be 11/4. keep 11/4, switch division to multiplication, and flip 4/3 to 3/4. multiply and get 33/16. 33/16 is improper so u have to change it. 33 goes into 16 twice and one is left. answer would be 2 and 1/16
that took a while

The photographer wants to mat his picture on a piece of cardboard. He is not sure if the cardboard is the right size. He has determined that the height (h) and the width (w) of the cardboard will be the right size if it satisfies the equation w-4/h-4 = 4/3. If the cardboard's height is 7, what is the width?
Answers
Answer:
8
Step-by-step explanation:
Since the cardboard’s height is 7, and 7-4 is 3, we can assume the width would be something - 4 = 4. 8-4 is 4, hence the answer is 8.

Help!!!! the integer that makes the following addition sentence true.

As you can see the end result will end up with -16
Answer:
-17
Step-by-step explanation:
I will represent the question mark with the variable [tex]x[/tex].
[tex]x - 11 + 12 = -16[/tex]
To solve for [tex]x[/tex], we need to isolate it.
To do this, subtract 12 from both sides.
[tex]x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28[/tex]
Then, add 11 to both sides.
[tex]x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17[/tex]
[tex]x = -17[/tex]
So, the integer that makes the equation true is -17.

Answer:
y=2x+10
Step-by-step explanation:
Perpendicular lines are lines that intersect at a 90 degree angle. Therefore, their slopes are the opposite sign and the reciprocal. The opposite reciprocal of -1/2 is 2. Then you just repeat the same process above to find the equation. m=2, x=-4, and y=2, so plugging in you would get 2 = (2)(-4)+b. Simplifying you get b=10 and so your equation for the perpendicular line that passes through (-4,2) is y=2x+10

Answers
Answer: Remove, Multiply, Add (RMA)
Step-by-step explanation:
I'll share a method I use. it is removed, multiply, and add. first, you have to remove the decimals from the problem, multiply them, and add the decimals back into the problem. count the number of how many numbers are behind the decimal. for example, let's take 3. after you multiply, count three spaces to the left and place the decimal. let's take 3.12 x 2.7. first, remove the decimals. after you do that, you're left with 312 x 27. do the multiplication, and then count the number of how many numbers are behind the decimals. so, that would be three. your answer for the mutiplication problem is 8,424. since there are three spaces, you would count one, two three. to the left of 8,424. therefore, the answer is 8.424

Answers
Answer:
BD = √(18² +4²) = √340; AD = √(12² +(√340)²) = 22AD = √(12² +18² +4²) = 22Step-by-step explanation:
You want the space diagonal of the given box (a) using the Pythagorean theorem twice, and (b) using the formula.
Pythagorean theorem twiceThe length of BD can be found from ...
BD² = BC² +CD²
BD² = 18² +4² = 340
BD = √340 ≈ 18.439
and
AD² = AB² +BD²
AD² = 12² + 340 = 484
AD = √484 = 22
The lengths of the face and space diagonals are ...
BD = √340 ≈ 18.439AD = 22FormulaNo formula is given as part of the problem statement. We can simplify the above calculations to get ...
AD² = AB² +BD²
AD² = AB² +BC² +CD²
AD = √(AB² +BC² +CD²) . . . . . . a reasonable formula
AD = √(12² +18² +4²) = √(144 +324 +16) = √484
AD = 22
