Answer:
[tex]Let~the~percentage~decrease~be~equal~to~y.\\Then,\\0.85x = x-\frac{y}{100}(x)\\or, 0.85x = x-0.01xy\\or, 0.85x = x(1-0.01y)\\or, 0.85 = 1-0.01y\\or, 0.01y = 1-0.85 = 0.15\\or, y =15\\So, ~the~decrease~of~the~price~is~15%.[/tex]
Alternative method:
[tex]Percentage~decrease = \frac{Initial~Rate-Final~rate}{Initial~Rate}(100) \\~~~~~~~~~~~~~~~~~~~~~~~~~~~~~=\frac{1-0.85}{1}(100) = 0.15(100)=15[/tex]
Answer:
thr percent decrease is 15%
Step-by-step explanation:
you get 1.00 which represent beginning price u subtract the current price 1.00-0.85 you get0.15 which is 15%

Given that lines q and m are parallel and are cut by two
different transversal lines, j and k, use angle relationships
to determine the measure of each numbered angle:
angle 1 = 180-110 = 70 degrees (linnear pair)
angle 2= 180-115 = 65 degrees (linnear pair)
angle 3 = angle 2 = 65 degrees (corresponding angles)
angle 4= 180 - angle 3 = 180-65 = 115 degrees (linnear pair)
(your teacher might not like this, depends on the cituation, but use 180 degrees in triangle to get 7)
angle 7 = 180 -angle1 -angle 2= 180-70-65= 45 degrees
angle 6 = angle 7 = 45 degrees ( vertical angles)
angle 8= 180- angle 7= 180-45 = 135 ( linnear pair)
angle 9 =angle 6 = 45 degrees (corresponding angles)
angle 5=angle 9=45 degrees (vertical angles)

2k+16=30 i need help with this before March 2nd ASAP
Answer:
k = 7
Step-by-step explanation:
The goal is to solve for the variable k in this problem.
To do this, we need to get k by itself!
2k + 16 = 30
Start by subtracting the 16 over from the left side to the right
2k + 16 - 16 = 30 - 16
Simplify by subtracting 16 from 16 on the left side (which is 0) and 16 from 30 on the right side (which is 14).
2k = 14
Then finish by dividing both sides by 2 to get k by itself.
[tex]\frac{2k}{2}[/tex] = [tex]\frac{14}{2}[/tex]
Simplify by dividing 2 by 2 on the left side (which is 1) and 14 by 2 on the right side (which is 7).
k = 7

Answer:
E = 80 degrees
Step-by-step explanation:
7x + 3 + x + 15 + 74degrees = 180
8x + 92 = 180
8x = 180 - 92
8x = 88
x=11
m<E = 7x + 3
7(11) + 3
77 + 3

A biologist estimates that the human body contains 90 pounds of water for every 100 pounds of body weight. At the rate estimate the number of pounds of water in a child who weighs 80 pounds
Answer:
72 lb
Step-by-step explanation:
Write and solve an equation of ratios:
80 pounds x
----------------- = ------------------
100 pounds 90 pounds
Cross multiplying, we get (100 pounds)x = 7200, or x = 72 pounds.
The 80 pound child's weight includes 72 pounds of water.

7. Find the value of x 8. find the value of y
Answer:
x = 27.8
y = 35
Step-by-step explanation:
∡D ≅ ∡A, therefore:
65 = 2y - 5
70 = 2y
y = 35
EF ≅ BC, therefore:
2x + y = 90.6
2x + 35 = 90.6
2x = 55.6
x = 27.8
Find the unknow measures of y and x.
9514 1404 393
Answer:
x = 2 m
y = 30°
Step-by-step explanation:
The side lengths of ΔDEF are 3/9 = 1/3 of those of ΔABC.
x = DF = 1/3(AB) = (1/3)(6 m)
x = 2 m
__
Angle measures of ΔDEF are the same as those of the corresponding angles of ΔABC.
y = ∠B = ∠E = 30°
y = 30°
