On a special two day clearance sale, 3 out of 5 books on clearance were sold on the first day of the sale. If 280 books were originally for sale on clearance how many were sold on the first day of the sale?
Answer:
168 books
Step-by-step explanation:
According to problem, given data are as follows:
Total books for sale = 280 books
Sold on first day = 3 out of 5 books
So, percentage of first day sold = 3 ÷ 5 = 0.6 or 60%
So, we can calculate the total books sold on day one by using following method,
Total books sold on first day = Total books for sale × percentage sold
By putting the value, we get
= 280 books × 60%
= 168 books
Make x the subject of m = n + X/P
Hello there, and welcome to Brainly!
In this case, x is to be made the subject of the equation, setting x by itself.
Note the equal sign, what you do to one side, you do to the other.
Do the opposite of PEMDAS. PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction
~
First, subtract n from both sides of the equation:
m (-n) = n (-n) + (x/p)
m - n = x/p
Next, fully isolate the x by multiplying p to all terms on both sides of the equation:
(p) * (m - n) = (x/p) * (p)
p * (m - n) = x
Next, simplify. Distribute p to all terms within the parenthesis:
p(m - n) = x
pm - pn = x
x = pm - pn is your answer.

If a computer price is reduced by 43% in a sale to £376.20, find the original price
Answer:
£874.88Step-by-step explanation:
sale price = £376.20
reduced by = 43%
original price = ??
sale price = original price ( reduced rate)
£376.20 = original price ( 43% )
100
original price = £874.88
Alice and Bob share an allotment. The ratio of the area of Alice's
portion to the area of Bob's portion is 3:2. They each grow
vegetables and fruit on the allotment. The entire allotment is
covered by vegetables and fruit in the ratio 7:3. On Alice's
portion of the allotment, the ratio of vegetables to fruit is 4:1
What is the ratio of vegetables to fruit in Bob's portion?
Answer:
11:39Step-by-step explanation:
Bob's portion of the allotment :
[tex]Total\:ratio=3+2 =5\\\\= \frac{2}{5}[/tex]
Alice's portion :
[tex]Total\:ratio=3+2 =5\\\\= \frac{3}{5}[/tex]
Vegetables are :
[tex]Total\:ratio=7+3 =10\\\\= \frac{7}{10}[/tex] of the total area
Vegetables are :
[tex]Total\:ratio=4+1 =5\\\\= \frac{4}{5}[/tex] of Alice's portion, or:
[tex]\frac{4}{5} \times(\frac{3}{5} ) = \frac{12}{25}[/tex]
Bob's portion fraction (b):
[tex]\frac{12}{25} + b = \frac{7}{10}[/tex]
L.C.M of 25 and 10 =50
[tex]\frac{24}{50} + b = \frac{35}{50} \\\\b =\frac{11}{50}\\\\ Ratio:\\50 - 11 = 39[/tex]
Bob's vegetable to fruit ratio is 11 : 39
What is the smallest positive perfect cube that is a multiple of 180?
THIS IS 20 POINTS!!!! Hope you have a great day! :D
Answer:Factor it into its prime factors:
180 / 2 = 90
90 / 2 = 45
45 / 3 = 15
15 / 3 = 5
5 / 5 = 1
2 x 2 x 3 x 3 x 5

What is the area, in square feet, of the shape below? Express your answer as a fraction in simplest form.
Answer: The area of the bottom figure is 5/8 ft²
Step-by-step explanation: The area of a triangle is half of the base times the height. Multiply the dimensions given, then divide by 2 or multiply by 1/2
The base of the top diagram is obscured by the timer.
The bottom will be 3/4 × 5/3
Multiply numerators straight across : 3 × 5 = 15
Multiply denominators straight across : 4 × 3 = 12
15/12 Simplify to 5/4 and take half (multiply by 1/2)
The result is 5/8 square ft.
The Area of the given triangle is [tex]\frac{5}{8} \; square feet[/tex], using the provided information base 5/3 feet and the length 3/4 feet.
Area of the triangleArea of the triangle is the area formed that is inside the triangle.
The formula for the area of the triangle is 1/2 times base times height
From the given diagram , the base of the triangle is 5/3 feet
height of the triangle is 3/4 feet
Subsitute the values of the base and height inside the formula
and find out the area of the triangle
[tex]Area = \frac{1}{2} \cdot base \cdot height \\Area = \frac{1}{2} \cdot \frac{5}{3} \cdot \frac{3}{4}[/tex]
Cancel out 3 from top and bottom
[tex]Area=\frac{5}{8}[/tex]
the Area of the given triangle is 5/8 square feet

Help me with this pls
Answer:
b = -1
Step-by-step explanation:
3 - 2(b - 2) = 2 - 7b (Use the distributive property)
3 - 2b + 4 = 2 - 7b (Add 3 and 4)
7 - 2b = 2 - 7b (Add 7b to both sides)
7 - 2b + 7b = 2 (Add -2b to 7b)
7 + 5b = 2 (Subtract 7 from both sides)
5b = 2 - 7 (Subtract 7 from 2)
5b = -5 (Divide both sides by 5)
b = -5/5 (Divide -5 by 5)
b = -1
Work Check: (Substituting b for -1)
3 - 2(b - 2) = 2 - 7b
3 - 2(-1 - 2) = 2 - 7(-1)
3 - 2(-3) = 2 - (-7)
3 - (-6) = 2 - (-7)
3 + 6 = 2 + 7
9 = 9
That is true, so b = -1
Aqua town charges 4.50 admission plus 0.75 for each ride the cost at splash world is 2.50 admission plus 1.25 per ride let x represent the number of rides write an expression for each water park to show the relationship between the total cost and the number of rides
Answer: Total cost at Aqua town = 4.50+0.75x
Total cost at Splash world = 2.50+1.25x
Step-by-step explanation:
Total cost = Admission charge + Charge per ride x Number of rides
Let x= Number of rides.
Aqua town charges 4.50 admission plus 0.75 for each ride.
Total cost at Aqua town = 4.50+0.75x
Splash world is 2.50 admission plus 1.25 per ride.
Total cost at Splash world = 2.50+1.25x
The required expressions:
Total cost at Aqua town = 4.50+0.75x
Total cost at Splash world = 2.50+1.25x

Find the value of each variable
Answer:
1. a=90; b=110
2. a=140
3. b=105
4. c=60
5. d=50
Step-by-step explanation:
For Problem 1, A can be found by adding up all the exterior angles and minus the final number by 360. The final number is 270, and 360-270=90, so a=90. To find b, you need to do 180-70=110, so b=110 Another way you could do it is get the original number as 360 and minus all the angles until you get the variable's angle.
For problem 2, you can do the same thing you did to find A in problem 1, which is 140.(360-120-100=140)
For problem 3, we can do the same as the problems before us, so b would be 105. (360-95-70-90=105)
For problem 4, we get c as 60 (360-55-55-90-100=60)
Problem 5 would be d=50 (360-70-70-70-60-40=50)

A group of people were asked if they had run a red light in the last year. 290 responded "yes", and 177 responded "no". Find the probability that if a person is chosen at random, they have run a red light in the last year.
Answer:
0.621
Step-by-step explanation:
Number of people that have run a red light in the last year = 290
Number of people that have not run a red light in the last year = 177
Total number of respondents = 290 + 177
= 467
Pr(if a person is chosen at random, they have run a red light in the last year) = [tex]\frac{number of people who has run the red light last year}{total number of respondents}[/tex]
= [tex]\frac{290}{467}[/tex]
= 0.621
The probability that if a person is chosen at random, they have run a red light in the last year is 0.621.
select the equation that represents a lone in which intercepts the vertical axis at b. assume m≠0, b ≠ 0, and m≠b.
A. y = mx
B. y = X
C. y = mx+b
D. y = m
Answer:
Option 'C' is correct.
Step-by-step explanation:
We know that the slope-intercept form of the line equation
[tex]y = mx+b[/tex]
where
m is the slopeb is the y-interceptWe are given that an equation that represents a line in which intercepts the vertical axis at b, assuming m≠0, b ≠ 0, and m≠b.
As the line intercepts the vertical (y-axis) at b.
Therefore, 'b' is the y-intercept of the line.
Also, the slope is m.
Thus, according to the slope-intercept form of the line equation, the equation is:
y = mx+b
Therefore, option 'C' is correct.
The table below represent which equation ?
Answer:
C

There are 17 animals in the barn. Some are chickens and some are cows. There are 56 legs in all. How many of each animal are there?
Answer:
6 chickens, 11 cows.
Step-by-step explanation:
x - chickens
y - cows
x + y = 17
2x + 4y = 56 <-- chickens have 2 legs, cows have 4.
y = -x + 17
Substitute (-x+17) for y in the second equation.
2x + 4(-x + 17) = 56
2x -4x + 68 = 56
2x = 12
x = 6 chickens
Now substitute 6 for x
6 + y = 17
y = 11 cows

Jenifer is flying her kite and it gets stuck in a tree. She knows the string on her kite is 16 feet long and she is 4 feet from the tree.
Answer: 15.49 ft
Step-by-step explanation:
The rest of the question is:
How long of a ladder (in feet) will she need to get her kite out of the tree? Enter your answer as a decimal rounded to two decimal places.
The scenario described forms a right angle triangle where:
Hypothenuse = 16 ft
Base = 4 ft
Height is the length of the ladder
This can be solved by the Pythagorean expression:
c² = a² + b²
Where:
c = hypothenuse
a = base
b = height
16² = 4² + b²
b² = 16² - 4²
b² = 256 - 16
b = √240
b = 15.49 ft
