You are told that the perimeter is 146 units. You look at the diagram and add up all the sides, which tells you the total perimeter. You then equate 146 and the total perimeter, as you know both these equal the perimeter. Then solve for x by using algebra.
Answer:
80%
Step-by-step explanation:
Given:
Team D used a recipe that consists of 20 cups of sand, 2 cups of flour, and 3 cups of water.
Question asked:
How does the percent of sand in Team D's recipe compare to that of the other teams ?
Solution:
Team D used a recipe that consists of sand = 20 cups
Team D used a recipe that consists of flour = 2 cups
Team D used a recipe that consists of water = 3 cups
Total number of cups together = 20 + 2+ 3 =25 cups
Now we will have to find percent of cups of sand out of the total number of cups.
By using formula of percentage,
Percent = 

Therefore, 80% of sand in Team D's recipe compare to that of the other teams.
Answer:
Colin's mean score = 17.10
The new mean is 18.00
Step-by-step explanation:
Given scores: 31, 10, 26, 16, 28, 31, 9, 11, 8, 1
number of terms: 10
mean is calculated by given formula = sum of all the data set/ number of terms in the data set.
mean for the 10 scores = (31+ 10+ 26+ 16+ 28+ 31+ 9+ 11+ 8+ 1 )/10
= 171/10 = 17.1
Colin's mean score = 17.10
____________________________________________
runs scored by Colin in 11th match = 27
number of terms: 11
new mean = new sum /number of terms
new mean = (old sum score + 27)/11 = (171+27)/11
new mean = 198/11 = 18
The new mean is 18.00
Answer:
5.24
Step-by-step explanation:
Step-by-step explanation:
marlena steps should look like this:
2x + 5 = -10 - x
(minus 5 from both sides)
2x = -15 - x
(add x to both sides)
3x = -15
(divide by 3)
x = -5
