I’d say 100° because it could not be 90° because it doesn’t have the symbol that indicates it. It also can’t be 45° because the angle is not acute. And you told us that it is not 170°, so the only viable answer is 100°. Hope that helped :)

I believe the answer will be 100 because it’s close to a 90 degree angle

Answer:

1/4

Step-by-step explanation:

To find the slope given two points

m = (y2-y1) / (x2-x1)

= (4-3)/(5-1)

= 1/4

The table shows the elevation in feet at the peaks of several mountains.

polet [3.4K]

Answer:

a) The equation to find the elevation of Mt. Wilson is $28,784.31=x+11,510.21$

b) The elevation of Mt. Wilson is $17,274.10\ ft$

Step-by-step explanation:

Let

x ----> represent the elevation of Mt. Wilson

y ----> represent the elevation of Snow Crest

we know that

$y=x+11,510.21$ ----> equation A

we have

$y=28,784.31\ ft$

Substitute the value of y in equation A and solve for x

$28,784.31=x+11,510.21$

$x=28,784.31-11,510.21$

$x=17,274.10\ ft$

Problem 22
$4x^2(2x^2+x-5) - x(x^3+5x^2-3) + 17$
$4x^2(2x^2)+4x^2(x)+4x^2(-5) - x(x^3)-x(5x^2)-x(-3) + 17$
$8x^4+4x^3-20x^2 - x^4-5x^3+3x + 17$
$7x^4-x^3-20x^2+3x + 17$

So the final simplified answer to problem 22 is
$7x^4-x^3-20x^2+3x + 17$

--------------------------------

Problem 23
$-2x(x^3-6x^2+6)+4x^3-(5x^4+10x)$
$-2x(x^3)-2x(-6x^2)-2x(6)+4x^3-(5x^4)-(10x)$
$-2x^4+12x^3-12x+4x^3-5x^4-10x$
$-7x^4+16x^3-22x$

So problem 23 simplifies to
$-7x^4+16x^3-22x$

---------------------------------------------------------

Problem 24
$4b[2a^2-5(3ab-2b^2)]+29ab^2$
$4b[2a^2-5(3ab)-5(-2b^2)]+29ab^2$
$4b[2a^2-15ab+10b^2]+29ab^2$
$4b[2a^2]+4b[-15ab]+4b[10b^2]+29ab^2$
$8a^2b-60ab^2+40b^3+29ab^2$
$8a^2b-31ab^2+40b^3$

So problem 24 simplifies to
$8a^2b-31ab^2+40b^3$

-------------------------------------------------

Problem 25
$2y(6x-4x^2y)+13x^2y^2-6$
$2y(6x)+2y(-4x^2y)+13x^2y^2-6$
$12xy-8x^2y^2+13x^2y^2-6$
$12xy+5x^2y^2-6$

The final answer for problem 25 is
$12xy+5x^2y^2-6$

Suppose the movie theater you work at sells popcorn I'm three different sizes. A small cost $2, a medium cost $5, and a large co

VMariaS [17]

Let, number of small, medium and large popcorn sold are s, m and l respectively.

So, s + m + l = 250 ....1)

Also, l = 2s ....2)

Total sum = $1726 = 2s + 5m + 10l .....3)

Putting value of l from 2) to 1) is :

s + m + 2s = 250

m + 3s = 250

m = 250 - 3s ....4)

Putting value of m and l in terms of s in equation 3)

We get :

2s + 5( 250 - 3s ) + 20s = 1726

7s = 1726 - 1250

s = 68

l = 136

m = 250 -3(68) = 46

Now,

$P_s=68\times 2 = \$136\\\\P_m = 46\times 5 = \$230\\\\P_l = 136\times 10 = \$1360$

Hence, this is the required solution.

I need help!!!!!!!!!!!!

Ainat [17]

Answer:

See explanation below.

Step-by-step explanation:

A number bond shows what two parts add to make the number. The 1 in the bigger circle is equal to the two small circles each 1/2.

On the number line you have drawn from 0 to 1 a bar. This is the whole number. Divide the bar with one line exactly at the half.

This now shows that two bars or 1/2 + 1/2 becomes 1 big bar or 1. This shows the same relationship as the number bond.
