Answer:

22.50m

Step-by-step explanation:

With the ground, the horizontal ground distance is the adjacent side, so by SOHCAHTOA, the ratio used is cosine, i.e.

Ground distance

= hypotenuse * cos(50°)

= 35 cos(50°)

= 35*0.64279

= 22.50m

B<br> 8<br> 7<br> Find the length of "e" to the<br> nearest tenth using the<br> Pythagorean Theorem.

Juliette [100K]

Answer:

≈ 10.63

Step-by-step explanation:

Pythagorean Theorem... Possibly the most easy theory in math once you understood it.

Here's the formula.

$A^2+B^2=C^2$

AB would be the hypothenuse

BC would be the opposite

CA would be the Adjacent.

But let's not make it complicated though, the question is actually quite easy.

You are asked to find AB, the hypothenuse.

The hypothenuse would be C.

BC and CA would be A and B.

It doesn't matter where are you going to place the numbers.

So, $7^2 + 8^2$

$7^2 + 8^2 = 49 + 64\\$

= 113

Now we would have to square root 113 since $A^2+B^2=C^2$

$\sqrt{113}$ is an irrational number, and the question asks you to round ro the nearest tenth.

$\sqrt{113}$ =10.63014581

≈ 10.63

Your answer would be 10.63

While eating lunch, Vivian ate 65% of the carrots she had in her bag. There were 20 carrots in her bag before she ate any. How m

Dovator [93]

Answer:

Vivian would have 7 carrots left to spare if she ate 65% of the carrots in the bag.

Step-by-step explanation: Since 65% of 20 carrots equals 13 carrots, we would do 20 - 13. In which equals 7 so she has 7 carrots left in fer bag

Equation: 20-x=?

Solution: 20 - 13=7

The area of a rectangular knitted blanket is 14 x^2 - 17 x -6. What are the possible dimensions of the blanket? Use factoring.

worty [1.4K]

It's unlikely that it the dimensions are either 14 and 1 in front of the x or 6 and 1 for the 6, but this is math, so you never know. I would try 7 and 2 and 3 and 2 and see what comes of it.

(7x 2)(2x 3 ) That looks promising. We'll put the 3 with the 2x. That leaves us with the signs. We need 17 to be minus

(7x 2)(2x - 3) that gives you - 21 x So the 2 with the seven has to be plus.

(7x + 2)(2x - 3) should be the the factored answer.
7x + 2 = 0 has no meaning. Measurements cannot be minus.

2x - 3 = 0
2x = 3
x = 3/2

If there are choices, please list them. That's as far as is possible.
