Answer:
$0.88
Step-by-step explanation:
cost per 1% = 22 ÷ 100 = 0.22
⇒ cost of 4% = 4 x 0.22 = 0.88
Or
4% = 4/100 = 0.04
⇒ 4% of 22 = 0.04 x 22 = 0.88
Step-by-step explanation:
I'm assuming the sequence is: -320, 80, -20, 5
Divide each term by the previous term to get the common ratio r
r = (term 2)/(term 1) = 80/(-320) = -1/4
r = (term 3)/(term 2) = -20/80 = -1/4
r = (term 4)/(term 3) = 5/(-20) = -1/4
No matter which term you pick (as long as it's not the first one) dividing it by the previous term leads to -1/4 or -0.25 as the common ratio
Answer: -1/4
It seems like none of the answer choices have -1/4 but it could be choice A was supposed to show "-1/4" instead of "-14"? Perhaps the division sign didn't show up for some reason?
Step-by-step explanation:
I don't know the area of the glass front of your largest building.
but just think :
1 gallon of fluid costs $12
1 gallon cleans 5000 ft²
so, now, find the area (ft²) of that glass front and see what number you have to multiply 5000 with to get the area of the glass front.
then, you have to multiply $12 with that same number, and you get the price.
let's say the building's glass front has 10000 ft².
what do I have to multiply with 5000 to get 10000 ?
this is the same question as how often fits 5000 into 10000 ? which is 10000 / 5000 = 2
and 12×2 = $24 as total cost to clean it.
our the building's glad front has 2500 ft².
what do I have to multiply with 5000 to get 2500 ?
this is the same question as how often fits 5000 into 2500 ? which is 2500 / 5000 = 1/2
and 12 × 1/2 = $6 as total cost to clean it.
The 20th term in the following arithmetic sequence1/2, 1, 3/2, 2... is 10 because;
the number are divided by 2
and the 20th number would be 20/2 which is equal to 10
-3(2x+y) im not great at this but you can checm if its right or not
