15. 1/2 base * <span>hight ,</span> 1/2 * 11 * 6 = the answer is 33 cm^2
16. The "median" is the "middle" value in the list of numbers. To find the median, your numbers have to be listed in numerical order from smallest to largest, so you may have to rewrite your list before you can find the median. So the answer is 155.
17. <span>The mean is the usual average, so I'll add and then divide. (33+25+42+25+31+37+46+29+38) / 9 = 34
18. You have to draw a plot.</span>
12√3 / 12
Step-by-step explanation:
this creates a 30,60,90 triangle and since we are trying to find the rising part of the run we are going to have to find the 60-degree angle part. So then we do 12 times root 3.
Given
Gina has 6 yards of ribbon.
She cuts the ribbon into pieces that each measures three fourths yard.
Find out how many pieces of three fourths yard does Gina have
To proof
let the number of pieces of the ribbon be x.
As given in the question
Gina has of ribbon = 6 yards
She cuts the ribbon into pieces that each measures three fourths yard
Than the equation becomes


solving the above equation
we get
x = 2 × 4
x = 8
Gina have 8 pieces of three fourths yard
Hence proved
One solution
Hope it helps
