HELP! Please! Find The Height.

Answers

The height is 9m, but I'm afraid I can't explain it well enough for you to be able to solve
a similar problem next period.

First of all, I think the drawing is confusing. You have to take control of your eyes
until they recognize that the dotted lines are in the back, and the solid lines are in
the front. Then you see that the bottom triangular face of the prism has a base
of 7 and a height of 1.9 . That makes the area of the base (1/2)(b h) = 6.65 m² .

The volume of the whole prism is (area of the triangular face) x 'H' = 59.85 .

H = 59.85 / 6.65 = 9 m³ .

And the part that's enough to make you really steamed up is: You don't need
those measurements of the top face at all . . . the 3m and 5m on top.

(2x -2 1/5 - -4) ÷ -5

Answers

Answer:

(-2x ÷ 5) - (9/5 ÷ 5) = -2/5 * x - 9/25

Step-by-step explanation:

To solve the expression (2x - 2 1/5 - -4) ÷ -5, we need to follow the order of operations, also known as PEMDAS.

1. First, simplify the expression inside the parentheses (-2 1/5 - -4).

To subtract a negative number, we can change it to addition. So, (-2 1/5 - -4) becomes (-2 1/5 + 4).

Next, let's convert the mixed number -2 1/5 to an improper fraction.

-2 1/5 = -11/5

Now we can add the fractions: -11/5 + 4.

To add these fractions, we need a common denominator. The least common denominator for 5 and 1 is 5.

-11/5 + 4/1 = -11/5 + 20/5 = 9/5

Therefore, (-2 1/5 - -4) simplifies to 9/5.

2. Now, let's substitute the simplified expression back into the original expression: (2x + 9/5).

3. Finally, divide the expression by -5: (2x + 9/5) ÷ -5.

To divide by a negative number, we can multiply the expression by -1 and then divide by 5.

(2x + 9/5) ÷ -5 = (-1)(2x + 9/5) ÷ 5

Applying the distributive property, we get:

(-1)(2x + 9/5) ÷ 5 = (-2x - 9/5) ÷ 5

To divide by 5, we can multiply each term by 1/5:

(-2x - 9/5) ÷ 5 = (-2x ÷ 5) - (9/5 ÷ 5)

Simplifying further:

-2x ÷ 5 = -2/5 * x

9/5 ÷ 5 = 9/25

Therefore, the final answer is:

(-2x ÷ 5) - (9/5 ÷ 5) = -2/5 * x - 9/25

Please note that this is the simplified form of the expression, assuming that no specific value for x is given.

the answer is -10x+9/25
