❄ Hi there,
let us revise the rounding rules and then, get down to rounding the number.
- If the number you need to round is followed by a number from 0 to 4, you round down.
- If the number you need to round is followed by a number that's 5 or more, you round up.
Now we can start the rounding process.
Reading the problem & the directions, we notice that we need to round to 3 decimal places (3 numbers after the decimal point).
Looking at the fourth number, we notice that it's less than 5.
∴ we need to round down ↡

Answer:
Step-by-step explanation:
<u>Given</u>
- x : y = 2 : 5, y is 80% of z
<u>Rearranging the ratios:</u>
- x/y = 2/5 ⇒ x/y = 0.4 ⇒ y = x/0.4 ⇒ y = 2.5x
- y is 80% of z ⇒ y = 0.8z
<u>Comparing the values of y:</u>
- 2.5x = 0.8z
- x/z = 0.8/2.5
- x/z = 0.32
- x/z = 32/100
- x/z = 8/25
- x : z = 8 : 25
2 divided by 47 so d....
Because they say fraction of this listed species are endangered plants
So you use total amount of endangered plant,2....and divide it by the total amount in the whole list 47
Answer:
7920 square feet.
step -by- step explanation.
From the the question, the
Length, l= 120 feet.
Width, w= 55% of l
This implies that;
w=0.55×120=66 feet.
Area of rectangle is given by the relation ;
By substitution,
Therefore the area of the rectangular stage is 7920 square feet.
