Solve: (they're fractions) 3/6x + 1/2=8/x+4/3 The answer is -9 but i dont know how to solve it. Work please or explanation why. Thanks.

Answers

Answer 1

Answer: 3/6x + 1/2 = 8/x + 4/3 I'm going to make common denominators so -

3/6x + 3/6 = 48/6x + 8/6
- 3/6x -3/6x

3/6 = 45/6x +8/6
-8/6 -8/6

-5/6 = 45/6x
·6x 6x

-5x = 45
÷ -5 ÷ -5

x = -9

PLS HELP FIRST CORRECT ANSWER GETS BRAINLIEST !! A pile of tailings from a gold dredge is in the shape of a cone. The diameter of the base is 34 feet and the height is 16 feet. Approximately, how many cubic feet of gravel is in the pile? Use π = 3.14.A. 14,527 ft³
B. 285 ft³
C. 4,840 ft³
D. 6,032 ft³

Answers

The volume of the cone is 4840 cubic ft if the diameter of the base is 34 feet and the height is 16 feet option (C) is correct.

What is a cone?

It is defined as a three-dimensional shape in which the base is a circular shape and the diameter of the circle decreases as we move from the circular base to the vertex.

$\rm V=\pi r^2(h)/(3)$

Volume can be defined as a three-dimensional space enclosed by an object or thing.

It is given that:

A pile of tailings from a gold dredge is in the shape of a cone.

The diameter of the base is 34 feet and the height is 16 feet.

As we know,

The volume of the cone is given by:

$\rm V=\pi r^2(h)/(3)$

r = 34/2 = 17 ft

h = 16 feet

Plug the above values in the formula:

$\rm V=\pi (17)^2(16)/(3)$

After solving:

V = 1541.33π cubic feet

Take π = 3.14

V = 1541.33(3.14) cubic feet

V = 4839.78 ≈ 4840 cubic ft

Thus, the volume of the cone is 4840 cubic ft if the diameter of the base is 34 feet and the height is 16 feet option (C) is correct.

Answer:

C: $V=4840 (2 s.f.)$

Step-by-step explanation:

The formula for the volume of a cone is:

$V= (1)/(3) \pi r^2h$

Therefore,

$V=(1)/(3)* 3.14*((34)/(2))^2* 16\n\nV=4840 (2 s.f.)$

36% of what number is 18? SHOW YOUR WORK

Answers

In order to solve this, we must first transform the percentage into a decimal. We can do this by either dividing it by 100, or (my personal shortcut) just shifting the decimal point over 2 places to the left.

36% = 0.36

Now, we just divide 18 by the decimal to find out what the original number was.

18 / 0.36 = 50

So 36% of 50 is 18.

Let's check our work. To check, we just need to multiply 0.36 * 50, since the word 'of' in mathematics always implies multiplication.

0.36 * 50 = 18

So our work was correct.
36% of 50 is 18.
Hope that helped =)

36% of 50 is 18

Change the percentage into a decimal by dividing by 100:
$(36)/(100) = 0.36$

Divide 18 by the decimal:
$(18)/(0.36) = 50$

kirby often forgets to switch the inequity sign when dividing a negative. when solving 3x-10≥x, should kirby collect the variables on the left or the right? why?

Answers

You should collect the variable on the left side since you can't have two variables of the same letter on each side.so you would take the variable from the right side and subtract it from the left. So subtract x on both sides. Your new problem is 2x-10 is greater than or equal to 0. Now you add 10 on both sides. Your new problem is 2x is greater than or equal to 10. Now divide by 2 on both sides. Your answer would be x is greater than or equal to 5

In the figure shown, line AB is parallel to line CD.

Part A: What is the measure of angle x? Show your work. (5 points)

Part B: Explain how you found the measure of angle x by identifying the angle relationships that you used along the transversal. (5 points)

AB and CD are parallel lines, and PQ and PR are transversals which intersect AB at P and CD at Q and R. Angle APQ is labeled as 65 degrees, angle QPR is equal to x, angle PRD is equal to 120 degrees.

Answers

Answer:

x = 55

Step-by-step explanation:

to find angle BPR you would do:

180 - 120 = 60

so BPR is 60°

now to find x you do this:

65 + 60 + x = 180

125 + x = 180

x = 55

Answer:

45 degrees
