Answers

Answer 1
Answer: 30,000 is already a whole, but you can add a period and a 0 to the end so it would be 30,000.0

a right triangle has legs measuring 4.5 meters and 1.5 meters the lengths of the legs of a second triangle are proportional to the lengths of the legs of the first triangle which could be the lengths of the legs of the second tiangle please answer i really need help in this question thanks

Answers


One approach that might be a great help would be if you would look
at the choices ... those things at the bottom of the question that you
didn't give us.

-- One leg is 3 times the length of the other leg.

-- Any right triangle that has one leg three times as long as the other
leg is similar to this triangle. 

I'll bet that if you look through the choices, you'll find one there.

Since they are proportional, it doesn't make much of a difference.

What is a factor tree, and how do you know when a factor tree is completed?(5th grade math Please help me.)

Answers

A factor tree starts with one number, such as 8. You draw to lines, and at the end of each is a possible way to divide 8, such as 4 and 2, because 4*2=8. Then, you divide 4 by 2, which is the only possible way without getting a 1 or a 4. Then, since 2 cannot be divided by 2 or 1.That is a complete factor tree. You can tell if a factor tree is over if you end up with a prime number.
A factor tree is a tree to represent what are the factors of the number.
Ex: 20:1,2,4,5,10

1x20
2x10
4x5
5x4
10x2
All of this equals 20

The rectangle shown is dilated by a scale factor of 4

Answers

Answer:

60 cm, 60 cm, 32 cm, 32 cm

Step-by-step explanation:

Multiply each length by the scale factor.

15 cm * 4 = 60 cm

8 cm * 4 = 32 cm

The dilated sides AB and CD will have a length of 60 cm.

The dilated sides AC and BD will have a length of 32 cm.

5-8|-2x|=-75 can someone show me how to solve this? Like the steps?

Answers

Sure, I can help you solve this equation step by step:

Given equation: 5 - 8|-2x| = -75

Step 1: Remove the absolute value by considering two cases:
Case 1: -2x is positive
Case 2: -2x is negative

Step 2: Solve for Case 1 (when -2x is positive):
5 - 8(-2x) = -75
5 + 16x = -75
16x = -75 - 5
16x = -80
x = -80 / 16
x = -5

Step 3: Solve for Case 2 (when -2x is negative):
5 - 8(2x) = -75
5 - 16x = -75
-16x = -75 - 5
-16x = -80
x = -80 / -16
x = 5

So, the solutions for the equation are x = -5 and x = 5.

You can verify these solutions by substituting them back into the original equation to make sure they satisfy the equation.

Answer:

No solution

Step-by-step explanation:

To solve the equation 5-8|-2x|=-75, we can follow these steps:

Step 1: Isolate the Absolute Value

We begin by isolating the absolute value term by adding 8|-2x| to bothsides of the equation:

  • 5-8|-2x|+8|-2x|=-75+8|-2x|

Simplifying the left side, we get:

  • 5=-75+|-16x|

Subtracting 5 from both sides, we get:

  • |-16x|=-80

Step 2: Remove the Absolute Value

Since the absolute value of a number is always positive, we can split the equation into two cases:

  • -16x=80 or -16x=-80

Step 3: Solve for x

Solving for x in the first case, we get:

  • -16x=80
  • x=-5

Solving for x in the second case, we get:

  • -16x=-80
  • x=5

Step 4: Check the Solution

We need to check if the solutions we found satisfy the original equation. Plugging in x=-5, we get:

  • 5-8|-2(-5)|=-75
  • 5-8|10|=-75
  • 5-80=-75 (which is false)

Therefore, x=-5 is not a solution.

Plugging in x=5, we get:

  • 5-8|-2(5)|=-75
  • 5-8|(-10)|=-75
  • 5+80=-75 (which is false)

Therefore, x=5 is also not a solution.
