Suppose I have a wooden cube, which I then split into eight equal pieces. If I give you two of those pieces, and then give you three more, what fraction of the original cube do I have left? Express your answer in decimal form.
Answer:
.625
Step-by-step explanation:
Since the amount of pieces are 8, and you gave 5 away, you have to divide 5 by 8. This gives you .625
Answer:
0.375
Step-by-step explanation:
You would have 3/8 of the original cube left. 0.375 in decimal form.

Is there
a way to place 29 books on shelves so
that each shelf has the same number of books,
with more than one book on each shelf?
Explain.
Answer:
no
Step-by-step explanation:
no because 29 is a prime number, meaning its only factors are 1 and 29. if you were to have more than 1 book on each shelf then you would go into half and quarters of books.
Answer:
29 is only divisible by 1 and 29
so
you could either do one on each shelf or all 29 on one shelf
What is 1/4=y/12 can't figure it out i believe its 3/12
9514 1404 393
Answer:
y = 3
Step-by-step explanation:
You are correct that ...
1/4 = y/12 = 3/12
This means y = 3, the numerator of the fraction with 12 as the denominator.
__
In the original equation, you can get there by multiplying both sides of the equation by 12 (the denominator under y).
12(1/4) = 12(y/12)
12/4 = (12/12)y . . . . simplify a bit
3 = y

Consider two consecutive odd positive integers. If their product is 23 more than their sum, what
are the two integers?
Answer:
Find two consecutive odd integers whose product is 23 more than their sum. Let x & x+2 be the 2 integers.
Step-by-step explanation:
The value of two consecutive odd positive integers are 5 and 6.
What are Integers?
A whole that can be positive , negative and zero is called integers.
Given that;
The product of two integers is 23 more that their sum.
Let two consecutive odd positive integers are x and x + 2.
Now, By the given condition we can formulate;
x (x + 2) = 23 + x + (x + 2)
x² + 2x = 23 + 2x + 2
x² + 2x = 25 + 2x
x² = 25
Take square root;
x = √25
x = ± 5
Since, Numbers are positive.
So, x = 5
And x + 1 = 5 + 1 = 6
Thus, The value of two consecutive odd positive integers are 5 and 6.

At a sale, coats were sold for $11 each. This price was 55% of a coat's original price. How much did a coat originally cost?
Answer:
The coat originally cost $20.
Step-by-step explanation:
The original cost is of x.
At a sale, coats were sold for $11 each. This price was 55% of a coat's original price.
This meas that:
[tex]0.55x = 11[/tex]
How much did a coat originally cost?
This is the solution for x for the equation above. So
[tex]x = \frac{11}{0.55} = 20[/tex]
The coat originally cost $20.
Answer:
20
Step-by-step explanation:
so when setting up you put 11/x=55/100 then cross multiply. then you should get 55x=1,100 .
divide 1,100 by 55 then you should get your answer which is
x=20 :)
( 15n2 - 5n + 45 ) ÷ 5
I'm assuming we need to simplify this expression. (Tip when you are writing n squared, please write n^2, not n2.)
Since we can see that there is a 5 in each term inside the ( ), we simplify have to remove that if the whole thing is going to be divided by 5.
Answer:
(15n^2-5n+45)/5
=3n^2-n+9
Answer:
3n^2-n+9
Step-by-step explanation:
You would want to divide the 5 between each of the terms. 15n^2 ÷ 5 is 3n^2. 15 ÷ 5 is 3. The n^2 stays, so 3n^2. -5 ÷ 5 is -1. We don't have to worry about writing the -1. Rather, just write the -n, it is the same as writing -1n. Lastly, 45 ÷ 5 is 9. You have to put the terms together in standard form. Standard form is just writing the numbers from greatest power to least power. The 3n^2 would come first since 2 is the greatest power. Next would be the -n, and lastly the 9. The 9 is the constant, which always comes last. A constant would be a number without a variable after it, like 2x is not a constant but just 2 is. Therefore, the answer is 3n^2-n+9.
Solve 2 sin 20 - tan 20 = 0 for 0 in [0°, 360°).
Any help would be really appreciated!
Answer:
Step-by-step explanation:
If there is a character you cannot type, such as θ, you are better off substituting a different letter, or describing it in words. For example, write it as "sinA" or "sin(theta)"
Never use 0 as a substitute for θ! 0 is a constant with a specific value.
Since the argument of the trig functions is an expression, you should put parentheses around it: sin(2A).
:::::
I used several trigonometric identities for this question:
Double-angle formula for sine: sin(2θ) = 2sinθcosθ
Double-angle formula for tangent: tan(2θ) = 2tanθ/(1-tan²θ)
Quotient identity: tanθ = sinθ/cosθ
Reciprocal identity: secθ = 1/cosθ
Pythagorean identity: 1+tan²θ = sec²θ
2sin(2θ) - tan(2θ) = 0
2sin(2θ) = tan(2θ)
2·2sinθcosθ = 2tanθ/(1-tan²θ)
2sinθcosθ = tanθ/(1-tan²θ)
2sinθcosθ = (sinθ/cosθ ) · 1/(cosθ(1-tan²θ))
2(1-tan²θ) = 1/cos²θ
2(1-tan²θ) = sec²θ
2-2tan²θ) = 1+tan²θ
1 = 3tan²θ
tan²θ = ⅓
tanθ = ±1/√3
θ = 30°, 330°

Answer:
[tex]Pay = \$1593.90[/tex]
Step-by-step explanation:
Given
[tex]Rate = \$23.10[/tex] --- first 40 hours
[tex]Rate = \$34.65[/tex] --- more than 40 hours
Required
Determine his pay for 46 hours
46 hours is greater than 40 hours. SO, we use the second rate to calculate is earnings.
[tex]Pay = Rate_2 * 46[/tex]
[tex]Pay = \$34.65 * 46[/tex]
[tex]Pay = \$1593.90[/tex]
Hence, his earnings is (d) $1,593.90
