A video store is offering 20% off all outdated videos. Let s be the original price of the purchase. Use the expression s-0.2s for the new price of the purchase. Write an equivalent expression by combining like terms.
Answer: The equivalent expression is:
new price = s*0.8
Step-by-step explanation:
When the original price of something is A, and we have X% off, the new price if that object will be:
New price = A - (X%/100%)*A
Like in this case, the original price is s, and the discount is 20%
Then the new price can be written as:
new price = s - (20%/100%)*s = s - 0.2*s = s*(1 - 0.2) = s*0.8
This is the equivalent expression we wanted to get.
Answer:
new price = s*0.8

a sixth grade student can complete 20 multiplication facts in one minute if you works at the same rate how long should it take him to complete 35 multiplication facts? [type answer as decimal number.]
Answer:
It should take him 1.75 minutes to complete 20 multiplication facts, which is the same thing as 1 minute and 45 seconds, or 105 seconds.
Step-by-step explanation:
a. If it takes him one minute to complete 20 multiplication facts, that's 3 seconds per question, because 60/20 = 3.
b. Multiply 3 x 35 questions to get 105 seconds.
c. Divide 105 seconds by 60 seconds (60 in a minute) to get 1.75 minutes, which is the same thing as 105 seconds.

Answer:
a) x = 2 b) y = 5
Step-by-step explanation:
For a)
NOTE: Since line EC bisects angle FEG, it will be divided into 2 equal parts
angle FEG = 58
angle FEC = 11x + 7
angle CEG = 11x + 7
So:
58 = (11x + 7) + (11x + 7)
58 - 7 - 7 = 11x + 11x
44 = 22x
x = 2
For b)
angle AED = 16y + 10
angle AED = 90°
90 = 16y + 10
90-10 = 16y
y = 80/16
y = 5

Pythagora's Theorem
In any right triangle, the square of the measure of the hypotenuse is the sum of the squares of the legs. This can be expressed with the formula:
[tex]c^2=a^2+b^2[/tex]
Where
c = Hypotenuse or largest side
a,b = Legs or shorter sides
The situation described in the problem forms a right triangle shown in the image below.
Applying Pythagora's Theorem :
[tex]10^2=9^2+x^2[/tex]
Solving for x:
[tex]x^2=10^2-9^2[/tex]
[tex]x^2=100-81=19[/tex]
[tex]x=\sqrt{19}=4.4[/tex]

Domingo is replacing the baseboards in his home and calculates that he will need 637.5 feet of wood. When he travels to the hardware store, he discovers that baseboards are sold in 7.5-foot lengths. How many boards will Domingo need to purchase?
Answer:
Number of boards= 85
Step-by-step explanation:
Giving the following information:
Total wood required= 637.5 feet of wood
The baseboards are sold in 7.5-foot lengths.
To calculate the number of boards, we need to use the following formula:
Number of boards= total wood required / foot per board
Number of boards= 637.5 / 7.5
Number of boards= 85

Find the area of the shaded region. Round your answer to the nearest hundredth.
6 m
IT T
24 m
The area is about
square meters
The area of the shaded region in the circle to the nearest hundredth is 1695.60 meter squared.
Area of a circle
area = πr²
where
r = radius of the circleThe area of the shaded portion is the difference of the area of the large and small circle.
Therefore,
area of the large circle = πr²
area of the large circle = 3.14 × 24²
area of the large circle = 3.14 × 576
area of the large circle = 1808.64 m²
Therefore,
area of the small circle = 3.14 × 6²
area of the small circle = 3.14 × 36
area of the small circle = 113.04 m²
The area of the shaded region = 1808.64 - 113.04 = 1695.6 m²

Jeremy is plotting a line with a slope of 3. He starts by plotting the point (-4,-3). He then plots a second point on the line 6 units to the right, and k units up. His value of k must be a. 9 b. 18 c. 2 d. 24
Answer:
27
Step-by-step explanation:
Slope = 3
(-4, - 3) (6, k)
(y2 - y1) /(x2 - x1) = 3
(k + 3) / (6 + 4) = 3
(k +3) / 10 = 3
k + 3 = 30
k = 30 - 3
k = 27

The number of fish in a lake decreased by 25% between last year and this year.
Last year there were 60 fish in the lake. What is the population this year?
Answer: This population, the population is 45 fish.
Step-by-step explanation: This problem can be solved by a rule of three.
Last year there were 60 fish in the lake. That was 100, that is, decimal 1.
This year it decreased 25%. So there 100%-25% = 75%, that is decimal 0.75. So
60 fish - 1
x fish - 0.75
This population, the population is 45 fish.

x 0 1 2 3 y 8 1 −6 −13 Is the relationship a linear function? How do you know? A. No; the change in x and the change in y is not constant. B. Yes; the change in x is constant and the change in y is not constant. C. Yes; the change in x is constant and the change in y is constant. D. No; the change in x is not constant and the change in y is constant.
Answer:
The correct option is C) Yes; the change in x is constant and the change in y is constant.
Step-by-step explanation:
Consider the table shown.
x y
0 8
1 1
2 -6
3 -13
Now observe the changes in x and y coordinates, if changes are constant then the given function is linear.
Consider the change in x coordinate.
1-0=1, 2-1=1 and 3-2=1
Now consider the change in y coordinate.
1-8=-7, -6-1=-7 and -13-(-6)=-13+6=-7
Since the change in x and y is constant the given relationship is linear.
Therefore, the correct option is (C) Yes; the change in x is constant and the change in y is constant.

A map has a scale of 1 cm to 14 km.
On the map, the distance between Manchester and London is 18.8 cm.
What is the real distance, in km, between Manchester and London?
Answer:
Real distance between Manchester and London = 263.2 km
Step-by-step explanation:
Given that:
A map has a scale of 1 cm = 14 km
Ratio = 1 : 14
Distance from Manchester to London = 18.8 cm
Let,
x be the real distance between Manchester and London.
Ratio = 18.8 : x
As the relationship is proportional,
1 : 14 :: 18.8 : x
Product of mean = Product of extreme
14*18.8 = x
x = 263.2 kilometers
Hence,
Real distance between Manchester and London = 263.2 km
