Answer:
C. 35
Step-by-step explanation:
According to the pie-chart, 14% of people chose walking.
14% of 250 is 35, so 35 people chose walking.
.14×250= 35
18 - 12 = 6. Because the top legs of the 2 triangles are congruent, you divide 6 / 2 to get 3 as their length. Then you can use the Pythagorean Theorem to solve for x.
3^2 + x^2 = 14^2
9 + x^2 = 196
x^2 = 187
x = sqrt(187)
The answer is In the picture
Answer:
Step-by-step explanation:
Let the price for children and adults package be represented with x and y respectively.
For the first week the sum of the package will be as follows:
3x+8y = 126
For the two weeks after:
6x+4y= 108
So, we will be having two equations
3x+8y = 126..... (1)
6x+4y= 108.......(2)
These are simultaneous equations
From equation 1
3x+8y = 126
3x = 126-8y
X = 126-8y/3 ............. (3)
Put equation 3 into 2
6 ( 126-8y)/3 +4y = 108
756-48y/3 +4y = 108
756-48y+12y/3 = 108
Cross multiplying
756-48y+12y= 108×3
756-48y+ 12y = 324
Collecting like terms
756-324 = 48y-12y
432= 36y
Divide both sides by 36
432/36 = 36y/36
y= 12
Substituting y into equation 1
3x+8= 126
3x+96=126
3x= 126-96
3x= 30
Divide both sides by 3
3x/3 = 30/3
x = 10
Hence for each of the packages for children and adults. It will be 10 and 12 respectively.
Perimeter=(2*length)+(2*width)
length=2*w
132=(2(2w))+(2w)
132=(4w)+(2w)
132=6w
w=22
l=44
