We would be solving for 'c', or the hypotenuse.

[tex]4^2+5^2=c^2\\\\16+25=c^2\\\\41=c^2\\\\\boxed{\sqrt{41}, -\sqrt{41} =c}[/tex]

What is the área of this figure? (I need the answer bc this Is due in 1 hr )

Answers

Answer: 353ft

Step-by-step explanation:

To work out what the area of this composite shape is, you would split it into two shapes; a square and a rectangle.

For the formula of the rectangle and square you would do base x height.

So,

For the square you do 13x13=169

For the rectangle you would do 23x8=184

Then to work out the total area of the two shapes you would add the two areas together.

169+184=353

how do you solve (7^-1)^-1 and 5^2 * 5^4 * 5^-3

Answers

Answer:

Step-by-step explanation:

exponents raised to a - power  is an inverse function probably not the right word

       a^-b    =  1/(a^b)     example       4^-2   = 1/(4^2)     =  1/16

so   (7^-1)^-1  is a double inverse which is back to the original number  7

      inverted 7 twice

      (7^-1)^-1     = (1/7)^-1     =  1/(1/7)     =   7     trust me or use your calculator

since the coeffients are the same  just add the powers...  some exponent rule

     5^2 * 5^4 * 5^-3   = 5^(2+4-3)   = 5³

here is it written out

5^2 * 5^4 * 5^-3    = 5²  ×   5^4   ×  5^-3    =   (5×5) × (5×5×5×5)  × (1/5×1/5×1/5)

    5×5 × 5× (5×5×5  × 1/5×1/5×1/5)           (5×5×5  × 1/5×1/5×1/5)  = 1

    5×5×5    = 5³

   so

a book has a hundred and twenty. I have read a quarter of the pages. How many pages do I have?

Answers

Answer:

You have 90 pages left.

Step-by-step explanation:

1/4 × 120 = 30 pages read

Therefore

120- 30

=90 pages left to read

Answer:

You read 30 pages of the book.

You have 90 pages left.

Step-by-step explanation:

120 total pages

⇒ 120 = 100%

[tex]\frac{1}{4}[/tex] pages have been read

⇒ [tex]\frac{1}{4}[/tex] = 25%

[tex]\frac{3}{4}[/tex] remaining

⇒ [tex]\frac{3}{4}[/tex] = 75%

120 x .25 = 30 pages read

120 x .75 = 90 pages unread

30 + 90 = 120

The volume of this cylinder is 175pi cubic units. What is the volume of a cone that has the same base area and the same height? Write your answer in terms of pi.

Answers

Answer: 58.33π units ³

Step-by-step explanation:

The volume of a cylinder = πr²h

The volume of a cone = 1/3πr²h

Since we have been told that the volume of this cylinder is 175pi cubic units and that the cone has the same base area and the same height, then the volume of the cone will be the volume of the cylinder divided by 3. This will be:

= 175π / 3

= 175/3π

= 58.33π units ³

The volume of the cone is 58.33π units ³

Answer:

183

Step-by-step explanation:

write an equation in slope-intercept for the line that has a slope of 1/2 and goes through the point (4, 7)

Answers

Answer:

y = 1/2x + 5

Step-by-step explanation:

The formula for an equation is y = mx + b

m is the slope. It is given

y = 1/2x + b

b is the y-intercept

In this case, we must substitute to find the y-intercept

We are given coordinate pair (4,7)

Plug our pair in and we get => 7 = 1/2(4) + b

=> 7 = 2 + b

easily, we find b = 5

We get our equation: y = 1/2x + 5
