140 gallons of water would it use for 10 loads of laundry.
What is meant by the term direct proportional?A direct proportion is an arithmetical comparison of two numbers whose ratio is comparable to a constant value. According to the proportion definition, two ratios are in proportion when they are equivalent. The proportions are indicated by the symbol "∝".For the given question;
The amount of water a washing machine uses varies directly with the number of loads it washes.
Let amount of water be 'w'.
The number of loads be 'l'
w ∝ l
w = kl
k = proportionality constant.
For, w = 28 gallons
l = 2 loads of laundry
Put in the equation;
28 = 2 k
k = 14
Now, when l = 10 loads of laundry, w = ?
w = 14 × 10
w = 140
Thus, 140 gallons of water would it use for 10 loads of laundry.

What is the percentage?The quantity of anything is stated as though it were a fraction of a hundred. A quarter of 100 can be used to express the ratio. Per 100 is what the term percent signifies. The symbol ‘%’ is used to symbolize it.
The percentage is given as,
Percentage (P) = [Final value - Initial value] / Initial value x 100
Tristan and two of his friends purchased tickets to a school play. Tristan paid for all the tickets with a $50.00 bill and received $23.00 in change.
Then the cost of the ticket will be
Cost = ($50 - $23) / 2
Cost = $27
If Tristan used a coupon for 25% off. Then the original price for all tickets will be
Original cost = $27 / 0.75
Original cost = $36
Then the cost of each ticket will be
Cost of each ticket = $36 / 2
Cost of each ticket = $18

A tree casts a show of 15 meters, while a 2-meter post nearby casts a shadow of 3 meters. How tall is the tree?
Answer:
10 meters tall.
Step-by-step explanation:
If the 2 meter post casts a 3 meter long shadow the ratio
is 3:2 where 3 is the shadow and 2 is the height.
3*5=15
2*5=10
Answer:
The tree is 10 meters tall.
Step-by-step explanation:
The tree's shadow is 5 times longer than the shadow of the post. So the height of the post times 5, which is 10 meters.

We're given
a₄ = 3a₁
a₇ = 2a₃ + 1
Since these numbers form an arithmetic progression, we have for some fixed constant d
a₂ = a₁ + d
a₃ = a₂ + d = a₁ + 2d
a₄ = a₃ + d = a₁ + 3d
and so on, up to
a₇ = a₁ + 6d
Rewrite the given equations in terms of a₁, then solve for a₁ and d :
a₁ + 3d = 3a₁
a₁ + 6d = 2 (a₁ + 2d) + 1
2a₁ - 3d = 0
a₁ - 2d = -1
(2a₁ - 3d) - 2 (a₁ - 2d) = 0 - 2 (-1)
2a₁ - 3d - 2a₁ + 4d = 0 + 2
d = 2
a₁ + 3d = 3a₁
3 (2) = 2a₁
a₁ = 3

The supplementary angle of 136° is
Answer:
i think it is 44
Step-by-step explanation:
I am sorry if it is wrong
Answer:
a 44 degree angle
Step-by-step explanation:
The supplement of a 136 degree angle would be a 44 degree angle because:
136 + 44 = 180.
136 + x = 180
136 - 136 + x = 180 - 136
x = 44

I am really confused on how to do this.
Step-by-step explanation:
Ok, so in a standard equation, there can’t be any fractions, so you would have to multiply everything by 3, making the equation 3y+3=2(x-8) (p.s. don’t multiply the parentheses, leave the numbers in them alone for now). Then, you would go through with the equation process: 3y+3=2x-16. You move the 3 over to the right to make 3y=2x-19. Move the x to the left, -2x+3y=-19. But, there is a problem. The first term of this equation can’t be negative(yes, in standard form, x has to come first). So, you have to multiply everything by -1, resulting in the answer 2x-3y=19. I hope this helps!(The format for a standard form equation is: Ax+By=C).
Alexa transports flowers for Rolling Rosie's Garden Center. On her last route, she earned $450.80. If Alexa earned $0.40 for every mile, how far did she drive?
Answer:
1127 miles
Step-by-step explanation:
Since on her last route, she earned $450.80. And she earned $0.4 for every mile.
The amount earned divided by the amount earned per mile would give us the value of distance covered.
Thus,
distance covered = [tex]\frac{450.80}{0.40}[/tex]
= 1127
Thus, the distance covered by Alexa on he last route is 1127 miles.
