Find the sum 1/2 + 3/8
Stels [109]

Answer: 7/8

Step-by-step explanation:

The easiest way to do this is to find a common denominator, so first we find out 2 times how much equals 8? 2x4 = 8. So with 8 being our common denominator, we have to multiple 4 to every number in the fraction 1/2. So 1x4 = (4/8) = 2x4. Then you just add the top numbers, so 4 + 3 = 7 and keep the denominator. 7/8.

The following table gives the outside temperature in degrees Fahrenheit on a summer afternoon:
makvit [3.9K]
A.
For 12 - 1,
82 - 78 = 4 degrees per hour

For 1 - 3:15,
(88 - 82) / 2.25 = 2.67 degrees per hour

For 3:15 - 4:30,
(93 - 88) / 1.25 = 4 degrees per hour

For 4:30 to 6,
(91 - 93) / 1.5 = 1.33 degrees per hour

The time intervals 12 to 1 and 3:15 to 4 had the fastest rate of change

The sum of two numbers is 20. One number is one less than twice the second number. What are the two numbers?
murzikaleks [220]

Answer: Hope this helps.

13, 7

Step-by-step explanation:

Number one is 13

Number two is 7

Well 7 x 2 = 14, 14-1 = 7, and 7+13 = 20 making the answers true.

I figured out this number by eliminating numbers, I started with 5, ended with 8 to make a range of the possible numbers. Since 5 was too low and 8 was too high I knew the number had to be either 6 or 7, so I did 7 and I got the answer.

Walking lights are placed around the perimeter of rectangular garden 30 feet be 16 feet and are placed 18 inches apart. How many
Masteriza [31]
Well we can find the perimeter by using the formula P=2L + 2W 
P=2(30) + 2(18)      P=60+36     P=96
I believe we can divide the perimeter by 18 to find the total amount of lights needed. 
96÷18=5.333333 
So we know at least 5 lights are needed.
I'm not sure if I'm correct, but I hope this helped anyways :)
