Answer 1

Answer:

16.2

Step-by-step explanation:

[tex]a^{2} + b^{2} = c^{2}[/tex]

10 squared = 100

19 squared = 361

361 - 100 = 261

square root of 261 = 16.2

[tex]10^{2} + 16.2^{2} = 19^{2}[/tex] is the equation

hope this helps

Mark brainliest please

Answer 2

Answer:

They say.. use Pythagorean theorem formula.... what is it? :) you have to remember it. I'll put it below in case you don't remember

Step-by-step explanation:

[tex]C^{2}[/tex] = [tex]A^{2}[/tex] +[tex]B^{2}[/tex]

and I know, you're thinking..... what's the deal with all the letters... how do I add those up? :D ..... you are right... you can't add letters... the letters are just the variables... or places holders for numbers... you can put many different numbers into each of them but... the relationship.... which is made by the equal sign.. must hold true for any numbers you put in for the variables.... sooo.. like this.. for your particular answer

[tex]19^{2}[/tex] = [tex]10^{2}[/tex] + [tex]y^{2}[/tex]

( notice I've put in a " y " , where there is a B in the formula above but that's just a letter... again.. which is just a variable... the place holder for a number... soooo..... )

361 = 100 + [tex]y^{2}[/tex] ( subtract 100 from each side of the " = " )

261 = [tex]y^{2}[/tex] ( to undo the square on the wye... square root both sides)[tex]\sqrt{261}[/tex] = y

my calculator tells me that [tex]\sqrt{261}[/tex] = 16.15549442

they say round to the nearest 10th... soooo..

16.2 is the answer :)

I have gotten 100% on the quiz. The answer is 4/5 square feet.

Step-by-step explanation:

The area of the rectangle with the given measurements is 4/5 square feet.

How to find the area of a rectangle?

The area of a rectangle can be found by multiplying the 2 adjacent sides of the rectangle. In a rectangle with sides l and b, the area can be found by A = l*b.

The length and width of the rectangle are given. We can find the area of the rectangle as follows:

[tex]\text{Area} =2\frac{2}{5} (\frac{1}{3} ) \text{ft}^{2}[/tex]

= (12/5) * (1/3) square feet

= 4/5 square feet

We have found the area of the rectangle with the given measurements to be 4/5 square feet. The correct answer is option C.

Can someone pls help me with this?

Answers

Answer:

the answer is d

Step-by-step explanation:

so for one do y-intercept has to be at (0,25) so we can eliminate answer choices B and C

the reason why it is not a is because a is moving out of constant rate of 25 when it needs to be moving at a constant rate like 10 D is the answer because it's moving at a constant rate of 10 and it has a y intercept of (0,25)

The answer is graph D

It starts out at 25 and each week the graph goes up only 10 dollars, so it’s the only one that makes sense. Good luck!!!

17. A rectangular prism has a length of 12 cm, a
height of 6/cm, and a width of 4 cm. Use the
formula SA = 2({w) + 2(wh) +2(ehy to find the
surface area of the rectangular prism.

Answers

Answer:

SA = 288 cm

Step-by-step explanation:

l = 12

w = 4

h = 6

SA = 2lw + 2wh + 2lh

SA = (2 x 12 x 4) + (2 x 4 x 6) + (2 x 12 x 6)

SA = 96 + 48 + 144
