Bill found a book he wanted on sale for $20.80. The original price of the book was $32. Find the discount rate.
Answer:
35% discount
Step-by-step explanation:
We can first find what percent of 32 20.80 is.
This can be shown by using a percent proportion.
[tex]\frac{20.80}{32} = \frac{x}{100}[/tex]
We can cross multiply to find the value of [tex]x[/tex].
[tex]20.80\cdot100=2080\\\\2080\div 32 = 65[/tex]
So 20.80 is 65% of 32.
However, this is the percent of the original price. To find the discount, we have to subtract 65 from 100.
[tex]100 - 65 = 35[/tex]
So the book was on a 35% discount.

A research organization studying families in various countries reported the following data for the amount of time that children spent with their fathers each day. What is the mode and the median, respectively? Country Time with Dad (minutes) Belgium 30 Canada 44 China 54 Finland 50 Germany 36 Nigeria 42 Sweden 46 United States 42 A. 42, 42 B. 42, 43 C. 43, 42 D. 43,43
Answer:B. 42, 43
Step-by-step explanation:
STEP 1 Listing out the data set
Country Time with dad
Belgium 30
Canada 44
China 54
Finland 50
Germany 36
Nigeria 42
Sweden 46
United States 42
STEP 2--- finding the mode and median
Mode----The mode of this data set is the number that occurs most frequently in this research date.
Time with dad in ascending order is given as 30, 36, 42, 42, 44,46,50,54
The number that occurred the most is 42 = mode
Median The median is the middle value in a data set
Since these data set is an even number, we take the average of the two middle numbers
Arranging in ascending order, we have
30, 36, 42, 42, 44, 46, 50, 54---------------42 and 44 are the middle numbers
42+ 44/2 =43
Therefore mode and median are 42 and 43 respectively
2/3 + 1/4

Angle sum property if Triangles tells us that sum of angles of a triangle is equal to 180°.
So, First, we will find the third inner angle.
[tex]180 = y + 93[/tex]
[tex]y = 87[/tex]
Now, let us find x.
[tex]62 + 87 + x = 180[/tex]
[tex]149+ x = 180[/tex]
[tex]x = 31[/tex]
So, 31° is the answer. (c)

Miles has 25 coins in his pocket. Some are nickels and some are dimes. He has a total of $1.65. How many of each type of coin does he have? Let x represent _____________________________ Let y represent _____________________________ System: _____________________ _____________________ Solution: x = ____________ y = ____________
Answer: 17 nickels, and 8 dimes.
Step-by-step explanation:
So Miles has 25 coins in his pocket, Suppose that x is the number of nickels, and y is the number of dimes, then we have that:
x + y = 25
And we also know that the total value is $1.65
Then we have that:
x*0.05 + y*0.10 = 1.65
Then we have a system of equations:
x + y = 25
x*0.05 + y*0.10 = 1.65
The first step is isolating one of the variables in one of the equations, i will isolate x in the first one.
x = 25 - y
Now we can replace that in the second equation:
(25 - y)*0.05 + y*0.10 = 1.65
Now we solve this for y.
25*0.05 - y*0.05 + y*0.10 = 1.65
1.25 + y*(0.10 - 0.05) = 1.65
y*0.05 = 1.65 - 1.25 = 0.40
y = 0.40/0.05 = 8
So Miles has 8 dimes.
And:
x + y = 25
x + 8 = 25
x = 25 - 8 = 17
And Miles has 17 nickels.

Step-by-step explanation:
A truck can be rented from Company A for $130 a day plus $0.50 per mile. Company B charges $50 a day plus $0.70 per mile to rent the same truck. How many miles
must be driven in a day to make the rental cost for Company A a better deal than Company B's?
For Company A to have a better deal, the truck must be driven more than miles per day
Answer:
The charges of both companies will be same if truck is driven 200 miles per day
Company A will have better deal if truck is driven more than 200 miles per day ( because per mile rate of company A is less than company B
Step-by-step explanation:
Let the truck is driven X miles per day
Charges of company A will be = 90+0.4X
Charges of company B will be =30+0.7X
Let us find out value of X when charges of both companies are same
which means that 90+0.4 X= 30+0.7X
90-30 = 0.7X-0.4X
60 = 0.3X
60/0.3 = X
X= 200
Answer:
200 miles

What is the substitution for the equation
Answer:
[tex]y=3x[/tex] (Equation 1)
[tex]y=x-2[/tex] (Equation 2)
We can substitute Equation 1 into Equation 2 like so:
[tex]y=x-2[/tex]
[tex]3x=x-2[/tex]
Subtract x from both sides:
[tex]2x=-2[/tex]
Divide both sides by 2:
[tex]x=-1[/tex].
Substitute [tex]x=-1[/tex] into Equation 1 to find y:
[tex]y=3x[/tex]
[tex]y=3(-1)[/tex]
[tex]y=-3[/tex]

How were the planets in the solar system formed?(1 point)
They developed from the dust that gravity attracted from distant galaxies.
They formed from material remaining after the sun's formation clumped together by gravity.
They came from the gas that the sun released and gravity pulled far away.
They were forced out of the central disc by the gravity that formed the sun.
Answer:
The various planets are thought to have formed from the solar nebula, the disc-shaped cloud of gas and dust left over from the Sun's formation. The currently accepted method by which the planets formed is accretion, in which the planets began as dust grains in orbit around the central protostar.
Step-by-step explanation:
Our solar system formed about 4.5 billion years ago from a dense cloud of interstellar gas and dust. The cloud collapsed, possibly due to the shockwave of a nearby exploding star, called a supernova. When this dust cloud collapsed, it formed a solar nebula—a spinning, swirling disk of material.
Answer:
The remaining materials from the sun's formation clumped together due to gravity.

9 - 10x = 2x + 1 - 8x
Answer:
[tex]x=2[/tex]
Step-by-step explanation:
[tex]9 - 10x = 2x + 1 - 8x[/tex]
[tex]9-10x=-6x+1[/tex]
Subtract 9 from both sides:
[tex]9-10x-9=-6x+1-9[/tex]
[tex]-10x=-6x-8[/tex]
Add 6x to both sides:
[tex]-10x+6x=-6x-8+6x[/tex]
[tex]-4x=-8[/tex]
Divide both sides by -4:
[tex]\frac{-4x}{-4}=\frac{-8}{-4}[/tex]
[tex]x=2[/tex]
Answer:
x = 2
Step-by-step explanation:
9-10x = 2x+1-8x
1. move all like terms to one side
-10x-2x+8x = -9+1
2. simplify
-4x = -8
3. divide the -4 from both sides of the equation
x= -8/-4

Answer:
100 kilometers
Step-by-step explanation:
In order to answer this question, we are going to have to do some multiplication, division, and conversion! To get started, we have to multiply 20 cm by 500,000 to expand the distance to full-scale:
20 * 500,000 = 10,000,000
This is how many centimeters (cm) are between the towns. Now, we have to convert this into kilometers (km). There are 100,000 centimeters in a kilometer, so to convert we have to divide 10,000,000 cm by 100,000:
10,000,000 / 100,000 = 100
Our answer is 100 kilometers.

A certain shampoo is available in two sizes. A 12.6-ounce bottle costs $2.37. A 25.3-ounce bottle costs $5.24.
Find the unit price for each size. Then state which size is the better buy based on the unit price.
Round your answers to the nearest cent.
Answer:
The 12.6 oz bottle
Step-by-step explanation:
0.19/oz for the 12.6 oz
0.21/oz for the 25.3 oz
The size is the better buy based on the unit price is 12.6 oz bottle if a certain shampoo is available in two sizes.
What is a linear equation?It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.
If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.
It is given that:
A certain shampoo is available in two sizes. A 12.6-ounce bottle costs $2.37. A 25.3-ounce bottle costs $5.24.
Let the unit price be x:
= 0.19/oz for the 12.6 oz
x = 0.21/oz for the 25.3 oz
Thus, the size is the better buy based on the unit price is 12.6 oz bottle if a certain shampoo is available in two sizes.
