Answer:
C. 4
Step-by-step explanation:
This is just a common ratio. These two triangles are alike, just that one is smaller than the other. You can see that one of the sides of the big traingle is 10. The same side of the smaller triangle is 5. That means the big traingle's side is twice as big as the small circle's.
10 divided by 5= 2
If the big triangle's side got divided by 2 to get the smaller triangle's side. So, that means the other side of the big triangle, 8 is twice as big as the side on the smaller triangle, x.
8 divided by 2= x
8 divided by 2= 4, so x= 4.
This is the ratio:
8:10 to x:5
As you can see the 10 got divided by 2 to get the 5. So 8 must also get divided by 2, which equals 4.
This is asking what can you raise 2 to in or order to get 4.
X=2
Answer:
PLAN A
$840-$180=$660
In 1 week = $60
how many weeks = $660
<u>$</u><u>6</u><u>6</u><u>0</u><u> </u><u>×</u><u> </u><u>1</u><u> </u><u>week</u>
$60
==== it will take 11weeks..
PLAN B.
In 1 week = $70
how many weeks= $840
<u>$</u><u>8</u><u>4</u><u>0</u><u> </u><u>×</u><u> </u><u>1</u><u> </u><u>week</u>
$70
====It will take 12weeks
PLAN A IS THE CORRECT ANSWER IT ONLY TAKES 11 WEEKS
Answer:
-420
Step-by-step explanation:
let the two consecutive integers be
x and (x + 1)
The product of two consecutive integers is 420
x(x + 1) = 420
Distribute
x² + x = 420
Subtract 420 from both sides
x² + x - 420 = 0
The constant is
-420
