Answer:
22 in
Step-by-step explanation:
<u>circumference of a circle = 2 π r</u>
where radius (r) = 7/2 in. = 3.5 in
C = 2 π (3.5)
= 22 in
Step-by-step explanation:
b is the equal ratios just divide 22 and 14 with 2 you gonna get you answer easily
Profit = revenue (income) - expenses
600 = 120x - 300
600 + 300 = 120x
900 = 120x
900/120 = x
7.50 = x ....this is how much 1 kg costs
so to cover her weekly expenses of 300, she would have to sell :
300/7.5 = 40 kg of cumin <===
Answer:
27 =x
Step-by-step explanation:
We can use proportions to solve this problem. Put the side of the small triangle over the same side of the large triangle.
x+8 10
------- = -------------------
2x-5 14
Using cross products
14 (x+8) = 10 (2x-5)
Distribute
14x+112 = 20x-50
Subtract 14x from each side
14x-14x +112 = 20x-50-14x
112 = 6x-50
Add 50 to each side
112+50 = 6x-50+50
162 = 6x
Divide by 6
162/6 =6x/6
27 =x
Answer:
The equation of the axis of symmetry is x = 7
Step-by-step explanation:
Mathematically, we have the equation of the axis of symmetry as;
x = -b/2a
where a is the coefficient of x^2 = 1
b is the coefficient of x which is -14
So, the equation of the axis of symmetry will be;
x = -(-14)/2(1) = 14/2 = 7
So the equation of the axis of symmetry is x =7
