what is the measure of angle JKL 70
Answers
Answer:
220°
Step-by-step explanation:
If you were to draw a line from points J and L to the center of the circle and call the center point O, angle JOL would be twice as much as angle JKL which is 140° according to a circle law. Since arc JL is 140°, arc JKL would be 220°, as an entire circle is 360°.

Answers
Answer:
the gross monthly income last month is $3,318.92

The computation of the gross monthly income last month is shown below:
= Total sales × commission percentage
= $82,968 × 4%
= $3,318.92
hence, the gross monthly income last month is $3,318.92
We simply multiplied the total sales with the commission percentage

A triangle has side lengths of (2u-4v)(2u−4v) centimeters, (10u+2w)(10u+2w) centimeters, and (w-7v)(w−7v) centimeters. Which expression represents the perimeter, in centimeters, of the triangle?
Answers
Answer:
3w−11v+12u
Step-by-step explanation:
2u−4v+10u+2w+w−7v
2u-4v+10u+2w+1w-7v
2u−4v+10u+2w+1w−7v
2u+10u−4v−7v+2w+1w
2u+10u −4v−7v +2w+1w
^12u ^-11v ^3w
12u -11v+3w
3w−11v+12u
The perimeter of the triangle is represented by the expression 3w−11v+12u.
What is the perimeter of the triangle?Triangle is a shape made of three sides in a two-dimensional plane. the sum of the three angles is 180 degrees. The perimeter of the triangle is defined as the sum of all the sides of the triangle.
Given that a triangle has side lengths of (2u-4v)(2u−4v) centimeters, (10u+2w)(10u+2w) centimeters, and (w-7v)(w−7v) centimeters. The perimeter of the triangle is calculated by adding all the sides of the triangle.
E = 2u−4v+10u+2w+w−7v
E = 2u-4v+10u+2w+1w-7v
E = 2u−4v+10u+2w+1w−7v
E = 2u+10u−4v−7v+2w+1w
E = 2u+10u −4v−7v +2w+1w
E = 12u -11v+3w
E = 3w−11v+12u
Therefore, the perimeter of the triangle is represented by the expression 3w−11v+12u.

PLS HELP. this is due soon,
only answer if you actually know it; no guessing for points please
Answers
Answer:
102
Step-by-step explanation:
x = 180 - (4x - 2) - 78
x = 180 - 4x + 2 -78
5x = 180 + 2 - 78
5x = 104
x = [tex]20\frac{4}{5}[/tex].
So, angle UTW is 4 * [tex]20\frac{4}{5}[/tex] - 2 + [tex]20\frac{4}{5}[/tex] = 5 * [tex]20\frac{4}{5}[/tex] - 2 = 104 - 2 = 102

The environmental club at Paul sells gum and candy bars as a fundraiser. One afternoon, they sold $200 worth of candy. They need to report how many of each item they sold for their club records. Maura knows that they sold 295 items that day. Candy bars sell for 75 cents, and gum sells for 50 cents. How many candy bars and gums did Paul sell?
Answers
Answer:
210 candy bars
85 gum
Step-by-step explanation:
$200=0.75cb+0.50gum
cb+gum=295
gum=295-cb
substitute
$200=0.75cb+0.50(295-cb)
$200=0.75cb+147.5-0.50cb
$200=0.25cb+147.5
0.25cb=52.5
