please help me with this ​

Answer:

the answer is D.  40.5 cm

Hey there!

7/4 = 35/m

CROSS MULTIPLY BOTH of your NUMBERS

7(m) = 4(35)

7(m) = 7m

4(35) = 140

NEW EQUATION: 7m = 140

DIVIDE 7 to BOTH SIDES

7m/7 = 140/7

CANCEL out: 7/7 because that gives you 1

KEEP: 140/7 because that gives you the value of m

140/7 = m

Solve above and you have the answer of m

140/7 = 20

Therefore, the value of m = 20

Answer: m = 20

Good luck on your assignment and enjoy your day!

Answer:

[tex]\frac{1}{81}[/tex]

Step-by-step explanation:

[tex]\frac{1}{3}[/tex] × [tex]\frac{1}{3}[/tex] × [tex]\frac{1}{3}[/tex] × [tex]\frac{1}{3}[/tex]

1 × 1 × 1 × 1 = 1

3 × 3 × 3 × 3 = 81

[tex]\frac{1}{81}[/tex]

Answer:

4

Step-by-step explanation:

3- 3

23 - 3

20 / 5 = 4.

Step-by-step explanation:

Answer:

The answer is 3,500 calories

Step-by-step explanation:

The reason why is because the area of the pan is 7/8 and a brownie has a area of 1/16 that means 14 brownies can fit in the pan and because each brownie 250 calories that means 14x250=3,500 calories your answer.

Answer:

D. 6x^4+3x^3y

Step-by-step explanation:

3x^3(2x+y)

distribute 3x^3

3x^3*2x+3x^3*y

=6x^4+3x^3y

To find the mean, add up all the numbers in the data set. After, divide by how many numbers are in the data set. Try it out with your data. If you need help with the actual answer, feel free to write in the comment box.

Answer:

2n^3

Step-by-step explanation:

Answer:

y= -1.328

Step-by-step explanation:

15= k*-18

15=k*-18 (divide both sides by -18)

It doesn't go in evenly so you are left with a negative decimal

k= -0.83

Now find y

y= -0.83(1.6)= -1.328

Answer:

D. is the answer

Step-by-step explanation:

the side lengths always have to be equal so 6+8 = 10    and 10 is equal to 10

that means it makes a right triangle

Answer:

x = 17

y = 8

QPR = 35º

QRP = 60º

Step-by-step explanation:

2x + 1 = x + 18

Subtract x from both sides

x + 1 = 18

Subtract 1 from both sides

x = 17

QPR = 2x + 1

QPR = 2(17) + 1

QPR = 35º

-------------------------------

8y - 4 = 4y + 28

Subtract 4y from both sides

4y - 4 = 28

Add 4 to both sides

4y = 32

Divide both sides by 4

y = 8

QPR = 8y - 4

QRP = 8(8) - 4

QRP = 60º

Step-by-step explanation:

5x-8x+12=24

-3x+12=24

-3x+12-12=24-12

-3x=12

-3x/3=12/-3

Answer is x = 12 :)

Operations you're supposed to do in order to solve this equation are:

1. Combine like terms

2. Subtract 12 from both sides

3. Simplify

4. Divide both sides of the equation by the same term

5. Simplify.

Answer:

x<7

Step-by-step explanation:

Answer: x=7, x<18, true

Step-by-step explanation: -10 becomes +10, then you add 10+18. 4x<28 is now the expressio. 28/4=7, x=7 and x or 7<28. This equation is true.

Answer:

  B.  45π cm^3

Step-by-step explanation:

The volume is given by ...

  V = 1/3πr^2h

where r is the radius (half the diameter) and h is the height. With the given numbers, we have ...

  V = (1/3)π(3 cm)^2(15 cm)

  V = 45π cm^3 . . . volume of each cup

Answer:

C

Step-by-step explanation:

ΔJKL consist of 3 angles: ∠mLJK, ∠mKLJ and ∠mJKL

We are given the measures of ∠mLJK and ∠mKLJ

In order to find ∠mJKH we must find the missing angle in the triangle

Remember that angles in a triangle add up to equal 180

If we are given two angles we can find the missing angle by subtracting the measures of the known angles from 180

so ∠mJKL = 180 - 37 - 69

180 - 37 - 69 = 74

Hence, ∠mJKL = 74°

Now to find ∠mJKH

Angles ∠K, ∠mJKH and ∠mJKL appear to be formed on a straight line

Angles formed on a straight line add up to equal to 180

So ∠K + ∠mJKH  + ∠mJKL = 180 ( note that this is the equation that will be used to solve for ∠mJKH )

∠K is a right angle, indicated by the little square.

Right angles have a measure of 90° so ∠K = 90

We have also calculated the measure of ∠mJKH = ( 74° )

That being said we plug in the given values into the equation created earlier and solve for ∠mJKH

We would have 90 + ∠mJKH + 74 = 180

Now we solve for ∠mJKH

step 1: combine like terms

90 + 74 = 164

now we have 164 + ∠mJKH = 180

step 2 subtract 164 from each side

180 - 164 = 16

164 - 164 cancels out

we're left with ∠mJKH = 16

Hence the answer is C
