P= 2L + 2 W = 50 P=50
W= L+ 5 Plug into equation (substitution)
2L +2 L+5 = 50
4L=50 -5
L= 45/4
L=11.25
P= 2 L + <u>(2 L +5)</u> = 50
P= 2(11.25) + 2(11.25) +5 =50
P=22.5 + 27.5
P=50 2L=22.5 and 2W= 27.5
L=11.25 W= 13.75
Answer:
3/2
Step-by-step explanation:
3/8 * 4/1 =
12/8 =
Simplifying gives 3/2 as our answer.
Answer:
3.8 × 10^{1}
Step-by-step explanation:
Calculating scientific notation for a positive integer is simple, as it always follows this notation: a x 10b.
Follow the steps below to see how 38 is written in scientific notation.
Step 1
To find a, take the number and move a decimal place to the right one position.
Original Number: 38
New Number: 3.8
Step 2
Now, to find b, count how many places to the right of the decimal.
New Number: 3 . 8
Decimal Count: 1
There are 1 places to the right of the decimal place.
Step 3
Building upon what we know above, we can now reconstruct the number into scientific notation.
Remember, the notation is: a x 10b
a = 3.8
b = 1
Now the whole thing:
3.8 x 10^{1}
Step 4
Check work:
10^{1} = 10 x 3.8 = 38
Answer:
Surface Area = 748 centimeters^2
Step-by-step explanation:
9 cm
23.5 cm
5 cm
Surface Area = 2×(9×23.5 + 9×5 + 23.5×5)
= 748 centimeters^2
Answer:
13/6 or 2 1/6
Step-by-step explanation:
6 1/2 = 13/2 (Improper Fraction)
1/3 = 2/6 (1/3 is just simplified)
1/3 x 1 + 1 + 4 + 6 + 1 = Answer
(13/2 x 1/3 = 13/6)
