Answer:

Q1. 4.5

Q2. 7

Q3. 306

Q4. 5/21

Q5. B. Cube

Q6. AEC and BED

Step-by-step explanation:

1. I found what 8*18 was, then I just divided that by 32 to find the missing value.

2. You want to reverse it and then solve so 56/8=7.

3. You can use a calculator for this 918/3=306

4. This you'd want to get the common denominators for each so just convert.

4/7*3/3=12/21

1/3*7/7=7*21

now just solve 12/21-7/21=5/21

5. Cube, there are 6 faces that are squares on it.

6. Acute angles are angles that are smaller than 90 degrees.

7. Feet, beds are long so feet are the best. Inches would be too little, miles are way too much, and gallons aren't even the right measuring unit.

8. So prime numbers are numbers that can only be divided by 1 and themselves so 1 is a prime number because if you divide 1 by 2 you get a fraction. So now we just want to find the prime numbers in this set.

1 is prime

2 is prime

3 is prime

4 is not prime; 4/2=2 whole number

5 is prime

this means that 4/5 numbers are prime, and 4/5=0.8 or 80%.

Hopefully, this helped you understand, feel free to lmk if you have any questions, and have a good day.

Answer:

2. 8x=56

divide both sides of the equation by 8

8x divided by 8=56 divided by 8

any expression divided by itself equals 1

x=56 divided by 8

calculate the quotient

x=7

3. 918 divided by 3= 306

4. answer is 5/21

5&6 not sure

7. inches

8. not sure

Use Pythogarean theorem to find c:
${a}^{2} + {b}^{2} = {c}^{2}$
Plug in the numbers:
${4}^{2} + {3}^{2} = {c}^{2} \\ \\ = 16 + 9 \\ \\ = 25 \\ \\ c = \sqrt{25} = 5$
c is 5.

Same thing with g:
${e}^{2} + {f}^{2} = {g}^{2} \\ \\ {g}^{2} = {4}^{2} + {4}^{2} \\ \\ = 16 + 16 \\ \\ = 32 \\ \\ g = \sqrt{32} = 4 \sqrt{2} = 5.66$
g equals 5.66.
