daniel has read 40% of a book. He has more 36 pages to finish. How many pages are there in the book?
Answers
Answer:
60 Pages.
Step-by-step explanation:
Using the given information, we can figure out that the remaining 36 pages are 60% of the book.
This is because 100% (whole book) - 40% (what you already read)= 60%= the remaining 36 pages
We can set up a problem to find 36 pages out of how many total pages is equal to 60%
(36/x) x 100 = 60%
=3600/60
=60 pages.
We can check our work by saying checking that 40% of 60 is 24, and 24+36 is 60 pages.

Answer:

Step-by-step explanation:
Option D is the only equation where the y-term gets eliminated upon simplifying

Diego collected x kg of recycling. Lin collected 2/5 more than that. [ Select ] Lin biked x km. Diego biked 3/10 less than that. y = 10/3x Diego read for x minutes. Lin read 4/7 of that. y = 7/4x
Answers
I assume you want to mathematically represent the above
Answer and explanation:
If Diego collected x kg of recycling and Lin collected 2/5 more than what Diego collected, then it would be represented mathematically thus:
Diego = x
Lin = x +2/5 of x= x+2/5x
if Lin biked x km and Diego biked 3/10km less than Lin, then we would represent this thus:
Lin=x
Diego= x-3/10 of x= x-3/10x
If Diego reads for x minutes and Lin reads 4/7 of what Diego read, then mathematically we represent this thus:
Diego=x
Lin =4/7 of x = 4/7x

Horse Of Course sells "Juan the horse" t-shirts for $23. Due to increased popularity, the store will raise the price by 8%. What will be the new price of the t-shirt?
Answers
Answer:
the new price of the t-shirt is $24.84
Step-by-step explanation:
The computation of the new price of the t-shirt is shown below
= Price of the t-shirt × (1 + increased percentage)
= $23 × (1 + 0.08)
= $23 × 1.08
= $24.84
Hence, the new price of the t-shirt is $24.84

Answers
Answer:
D, 30%
Step-by-step explanation:
you move the decimal point twice to the right
Answer:
D. 30%
Step-by-step explanation:
This is the answer because:
1) When you convert decimals to percents, you have to remember the two main decimal places:
0.00 = The hundredths place
0.00 = The tenths place
2) Whenever there is a decimal that is in the hundredths place, it will equal a one digit percent. For example, 0.07 = 7%.
3) Whenever there is a decimal that is in the tentsh place, it will equal a two digit number. For example, 0.3 = 30%.
4) Another way to solve it is to convert the decimal to a percentage by multiplying the decimal by 100 .
Therefore, the answer is 30%.

The dance committee of Pine Bluff Middle School earns \$72$72dollar sign, 72 from a bake sale and will earn $4 dollar sign, 4 for each ticket they sell to the Spring Fling dance. The dance will cost $400. Write an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this year's dance.
Answers
Answer:
t > 82
Step-by-step explanation:
Given that,
The dance committee of Pine Bluff Middle School earns $72 from a bake sale and will earn $4 for each ticket they sell to the Spring Fling dance.
The dance will cost $400.
We need to find an inequality to determine the number, t, of tickets the committee could sell to have money left over after they pay for this year's dance.
The committee earns $4 for each ticket. It means they will earn $4t.
$72 is constant as they earn it from bake sale.
The total earning must be greayer than $400.
ATQ,
4t + 72 > 400
We can solve the above inequality to find the value of t.
4t > 328
t > 82
Hence, the committee could sell more than 82 tickets to have money left over after they pay for this year's dance.

Answers
Answer:
Constants are the terms in the algebraic expression that contain only numbers. That is, they're the terms without variables. We call them constants because their value never changes, since there are no variables in the term that can change its value.
An algebraic expression is one or more algebraic terms in a phrase. It can include variables, constants, and operating symbols, such as plus and minus signs.

Step-by-step explanation:
20x² = y - 24
y = 20x² + 24
For y to have the least possible value, x² have to be the least possible, which is 0.
Since -3 <= x <= 2 includes x = 0, this is allowed.
Hence least possible value of y
= 20(0)² + 24 = 24.
Answer:
24
Step-by-step explanation:
-3---> 20(-3)^2=y-24 ----> y=204
-2---> 20(-2)^2=y-24 ----> y=104
-1---> 20(-1)^2=y-24 ----> y=44
0---> 20(0)=y-24 ----> y=24
1---> 20(1)^2=y-24 ----> y=44
2---> 20(2)^2=y-24 ----> y=104

PLEASE HURRY Find the midpoints between points C (7, -9) and D (3, 5).
Answers
Answer:
(5,-2)
Step-by-step explanation:
Midpoint formula
If we have coordinates (x₁,y₁) and (x₂,y₂), then the midpoint of these coordinates is determined by (x₁ + x₂)/2, (y₁ + y₂)/2. This forms a new coordinate you can call (x₃,y₃). The midpoint calculator will solve this instantaneously if you input the coordinates. Follow the steps above if calculating by hand.
For small numbers, it's easy to calculate the midpoint by hand, but with larger and decimal values, the calculator is the simplest and most convenient way to calculate the midpoint.
Answer:
Midpoint=(5,−2)Step-by-step explanation:
Midpoint formula
m=((x1+x2)/2,(y1+y2)/2
so lets plug in
((7+3)/2,(-9+5)/2)
