Step-by-step explanation:
<u>Step 1: Complete the first equation</u>
0.1 is a tenth, therefore if we have 15.3 then we have 153 tenths.
Step 2: Complete the second equation
15.3 / 3 = 5.1
0.1 is a tenth, therefore if we have 5.1 then we have 51 tenths.
<u>Step 3: Complete the third equation</u>
15.3 / 3 = 5.1
Answer:
j=76 and k=65
Step-by-step explanation:
<span>If Hunter raises beetles in a square of compost with a size of 6 ft by 6 ft and having 500 beetles, and then you are to find the number of beetles with a side length that is four times longer, then you can solve this by ratio and proportion.
A = s</span>²
A = 6²
A = 36 ft²
if s = 4*the original length, then the new area is
A = 24²
A = 576 ft²
500 beetles/36 ft² = x number of beetles/576 ft²
x = 8,000 beetles
C. 4
Look at where segment A'B' intersects, at x = 8.
Look at where segment AB intersects, at x = 2.
AB is smaller then A'B' that means the scale factor is
.
Hope this helps.
Answer:
<u>4 hours</u>
Step-by-step explanation:
Equations :
Larry : <u>y = 20x + 90</u>
Barry : <u>y = 30x + 50</u>
Equate both to find the number of hours at which they both charge the same :
- 20x + 90 = 30x + 50
- 30x - 20x = 90 - 50
- 10x = 40
- x = <u>4 hours</u>
