skateboard is priced for $38. They are having a sale for 20% off. how much is the discount and what is the selling price

Answer:

Step-by-step explanation:

using supplementary angles we can fine that two angles of a straight line =180

128+?=180 ?=180-128=52

126+?=180 ?=180-126=54

all angles of a triangle add up to 180 degrees

180=52+54+?

94=?

180-94=x

106=x

Answer:

Percent decrease = 10.43% (Approx)

Step-by-step explanation:

Given:

Old price = $1.15 million

New price = $1.03 million

Find:

Percent decrease

Computation:

Percent decrease = [(Old price - new price)/Old price]100

Percent decrease = [($1.15 million - $1.03 million)/$1.15 million]100

Percent decrease = [($0.12 million)/$1.15 million]100

Percent decrease = 10.43% (Approx)

Answer:

SRQ = 66 degrees

Step-by-step explanation:

QRT = 33 degrees

A bisector bisects angles evenly, which means that SRTis also 33 degrees. ADD these two together you get 66 degrees for this angle.

Answer:

<SRQ = 66

Step-by-step explanation:

bisect means to "cut" in half so the line pretty much separates half and half

Answer:

x+y=5

Step-by-step explanation:

Isolate y in the first equation:

3x+ 2y = 10

2y = 10 - 3x

y= (10 - 3x)/2

substitute this value of y into the second equation:

2x + 3 ((10 - 3x)/2) = 15

now solve for x:

2x + 3/2 (10 - 3x) =15

2x + 15 - 9/2x = 15

-5/2 x = 15 - 15

-5/2 x / (-5/2) = 0/(-5/2)

x=0

now use this value to solve for y:

y = (10 - 3(0))/2

y = 10/2

y = 5

now x+y

0+5=5

Answer :A.

Answer:

Unlimited number of triangles.

Step-by-step explanation:

Unlimited number of triangles can be made because Kendra has unlimited supply of unbreakable sticks. If she has limited number of sticks suppose 90 sticks so she can be able to made 30 non-congruent triangles from these number of sticks so if the number is not known so we are unable to say about the number of triangles should be made from unlimited unbreakable sticks.

Answer:

Step-by-step explanation:

The approximate cost of one vitamin is $0.04 thus option (A) is correct.

The ratio is the division of the two numbers.

For example, a/b, where a will be the numerator and b will be the denominator.

Proportion is the relation of a variable with another. It could be direct or inverse.

As per the given number of pills and cost.

The cost per pill from the first raw = $2.05/50 = $0.041

The cost per pill from the second raw = $4.10/100 = $0.041

The cost per pill remains constant in all so this is a direct proportion.

Hence "The approximate cost of one vitamin is $0.04".

Answer:

x = 100

Step-by-step explanation:

1. To get rid of the denominator of 5, multiply both sides of the equation to get 5

-40 + x = 60

2. Add 40 on both sides to get the variable x by itself

x = 60 + 40

3. Solve

x = 100

Answer:

x=100

Step-by-step explanation:

-8+x/5=12

--8+x/5=12+8

x/5=20

5*20=100

x=100

Answer:

the interest rate on this investment k = 0.05 or 5%

Step-by-step explanation:

Given that;

dp/dt = kp

dp/p = k dt

now we integrate on both sides

integral dp/p = integral k dt

ln p = kt + c

p =e^kt + c

p = ce^kt

Given that p = $180,000 is invested (when t = 0)

p = ce^kt

we substitute

180000 = ce^k×0

180000 = ce^0

180000 = c × 1

c = 180,000

we substitute the value in the equation

p = 180000e^kt

now given that the amount in the account after 17 years is $421,136

i.e at t = 17 and p = 421,136

we substitute

421,136 = 180000e^17k

divide both sides by 180000

421136/180000 = 180000e^17k / 180000

e^17k = 2.3396

17k = In(2.3396)

17k = 0.8499

k = 0.04999 ≈ 0.05

therefore the interest rate on this investment k = 0.05 or 5%

It is in fact 113 I'm just here to explain

Step-by-step explanation:

Basically M6 and M7 must make a staright line(180) and since we already know that M6 is 67 we just have to subtract 67 from 180 to get the answer we are looking for. ( it would be the same process if we were looking for M1 (113) and also if you had the measure of M1 you would have had your answer to M7 because they are vertical angles therefore making them congruent

Answer:

72 square units

Step-by-step explanation:

The area of the rectangle in the middle: 6x8 = 48 square units

The area of the triangle on the left: (5x6)/2 = 30/2 = 15 square units

The area of the triangle on the right: (3x6)/2 = 18/2 =9

(The 6 for the height of the triangle on the right is from the left side of the rectangle in the middle, they have to be the same length)

48+15+9 = 72 square units

Answer:

y=-5/2x-16

Step-by-step explanation:

1. Find the slope using the slope formula and the two coordinates provided.

m=y2-y1/x2-x1

Put the y values from both coordinates on top and the x values on bottom.

-6--5/-4--6

Solve for M. -6--5/-4--6 = -6+1/-4+6

= -5/2

Slope is -5/2.

2. Using the slope and one of the coordinates (doesn't matter which), put the equation in point-slope form: y-y1=m(x-x1)

y+6=-5/2(x+4)

3. Distribute the -5/2 to x+4 and simplify (multiply x and 4 by -5/2)

y+6=-5/2x-10

Subtract 6 from both sides to get y by itself.

y=-5/2x-16

4. y=-5/2x-16 is your answer

Ounces of orange juice in mixed fruit juice = 1.872

Ounces of mixed fruit juice = 6.65 ounces

Ounces of Mixed fruit juice that is not orange juice :

(Ounces of mixed fruit juice - Ounces of orange juice)

(6.65 - 1.872) ounces
