If one pound of apples cost 50 cents about how much would one apple cost
Answer: It depends on the weight of an apple. If 1 apple = 0.50 lb, then 1 apple costs $0.25
Step-by-step explanation:
We need to know the weight of one apple. If one apple weighed 0.5 lb, on the average, then:
($0.50/lb)*(0.5 lb/apple) = $0.25/apple

pls check this site
Step-by-step explanation:
Answer:
104 m²
Step-by-step explanation:
There is a 1 m sidewalk around the garden
Then length = 30 + 1 + 1 = 32 m
and width = 20 + 1 + 1 = 22 m
Area = 32 × 22 = 704 m²
Area of garden = 30 × 20 = 600 m²
Area of sidewalk = 704 - 600 = 104 m²
Graph the following equations.
X=1
Answer:
Vertical line that passes over 1 the x axis. (No y-intercept)
Step-by-step explanation:
Solve the simultaneous equations.
x + 2y = 9
5x – y = – 10
Answer:
(- 1, 5 )
Step-by-step explanation:
Given the 2 equations
x + 2y = 9 → (1)
5x - y = - 10 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
10x - 2y = - 20 → (3)
Add (1) and (3) term by term to eliminate y
11x + 0 = - 11
11x = - 11 ( divide both sides by 11 )
x = - 1
Substitute x = - 1 into either of the 2 equations and solve for y
Substituting into (1)
- 1 + 2y = 9 ( add 1 to both sides )
2y = 10 ( divide both sides by 2 )
y = 5
solution is (- 1, 5 )
x + 2y = 9 x + 2y = 9
=====》
5x - y = - 10 (×2) 10x - 2y = - 20
+____________
11x + 0 = - 11
11x = - 11
x = - 1
Thus :
- 1 + 2y = 9
Add both sides 1
2y - 1 + 1 = 9 + 1
2y = 10
Divide both sides by 2
2y ÷ 2 = 10 ÷ 2
y = 5

x = - 1 & y = 5What is the logarithmic formula 10000= 625/8*2^t ?
9514 1404 393
Answer:
log(128) = t·log(2)
Step-by-step explanation:
You can take logarithms the way the formula is, or you can simplify it first.
As is
log(10000) = log(625) -log(8) +t·log(2)
__
Simplified
8·10000/625 = 2^t . . . . . multiply by 8/625
128 = 2^t
log(128) = t·log(2)
_____
Solution:
t = log(128)/log(2) = 7

What is an equivalent ratio of 5:9
Step-by-step explanation:
There is infinitely many ratios which are equivalent to 5:9. As we know always we can write divide as fraction, so . We can multiply nominator and denominator by the any number (but the same) and get another numbers but ratio will be the same, so equivalent.
For example
10:18,
15:27
Hope this helps.
Answer:
10:18
Step-by-step explanation:
Anything really just times both sides by the same number.
For example to get to 10:18 I multiplied both sides of 5:9 by 2.
If you were to multiply 5:9 by 3 (which would 15: 27) it would still be an equivalent to 5:9.
All of the following are equivalent fractions except
8/40
3/15
6/30
5/20

Find the area of a rectangular garden plot that measures 21 ft by 25.2 ft. Report with the correct number of significant digits.
The area of a shape is the amount of space it occupies.
The area of the garden is 529.2 square feet
The given parameters are:
Shape: Rectangle
Dimension: 21ft by 25.2ft
The area of a rectangle is:
[tex]\mathbf{Area = Length \times Width}[/tex]
So, we have:
[tex]\mathbf{Area = 21 \times 25.2}[/tex]
[tex]\mathbf{Area = 529.2}[/tex]
Hence, the area of the garden is 529.2 square feet

MONEY PRIZE FOR THE FIRST PERSON TO GET THIS RIGHT AT THE END OF THE PROBLEM LIST METHOD OF ONLINE PAYMENT YOU WANT!
Situation: You love to knit sweaters and you want to start a small business to make money from your talent. You want to do the math first to find out how long it will take for you to make a profit. You must pay a fixed fee of $90.00 to start the company up plus $15.00 for each sweater to pay for the yarn. You want to charge $30.00 for each sweater that you sell.
1. Write an equation for the cost of the company
Choose and define your variables in words:
x:
Equation: y:
2. Write an equation for the money made, INCOME (NOT PROFIT ALL INCOME), selling sweaters
Choose and define your variables in words:
x:
Equation: y:
After you have your equations:
-Find the cost and income when you sell 2 sweaters. (You should have two different answers because you had two different equations one for the INCOME and one for the COST!)
Hints: REMEMBER X is your independent variable so look at the independent number or thing about the problem and write it for x: . Also REMEMBER Y is your dependent variable so whatever your x is y will depend on it if X changes Y also changes look at the problem and ask yourself "What has an effect on what? and "What is effected by what?" This will help you answer the problem.
Answer:
1. y = 90x
x: the amount of companies to start
y: The total amount it will cost.
2. y = 30x
y: the total income
x: the amount of sweaters being sold.
The answer to the last question(I think would be):
cost: $30
income: $60
as:
equation to find cost = y = -15x
equation to find income = y = 30x

Multiply the roots of the first and third terms together. Compare to the middle terms with the result in step two. If the first and last terms are perfect squares, and the middle term's coefficient is twice the product of the square roots of the first and last terms, then the expression is a perfect square trinomial.
