The answer i think it is, is C
Base of the courtyard = sqrt(90) = 3sqrt(10)
Height of the courtyard = 10 + sqrt(3)
Area of the courtyard = 1/2 x 3sqrt(10) x (10 + sqrt(3)) = 15sqrt(10) + 3/2sqrt(30)
Answer:
B) $43.40
Step-by-step explanation:
For the tax, 6% of 35 = 2.1
So with tax = $35 + 2.1 = $37.1
18% tip
So, 18% of 35 = 6.3
So we are gonna add all the costs together = 37.1 + 6.3 = $43.40
I think it's;
Ratio of areas = 8:3
Wideness of the the shape = 32 cm
8:3 = 32:X
8/3 = 32/x
x = 8*3/32
= 0.75
Not too sure about the answer
Answer:
After 4 months
Step-by-step explanation:
The cost at both the programs consists of a "fixed cost" (reg fee) & "variable cost" ( per month fee).
Let number of months be "x"
<u>Yo-Yoga:</u>
35 fixed
90 per month
So equation would be: 35 + 90x
<u>Essence Yoga:</u>
75 fixed
80 per month
So equation would be: 75 + 80x
To find number of month when cost would be same, we equate both equations and solve for x:
35 + 90x = 75 + 80x
10x = 40
x = 40/10
x = 4
hence, after 4 months, both cost would be same
