Answer:
The estimated percentages i could think of were 2/9, 1/3, 23/90, 20/90
Step-by-step explanation:
estimates include rounding. So i rounded to the nearest fractions and picked out the best ones.
Answer:
10
Step-by-step explanation:
We need to solve the equation . The equation is z
→ 60 = 70 - h
- Subtracting 70 both sides .
→ 60 - 70 = 70 - h - 70
→ -10 = -h
- Dividing both sides by -1 .
→ -h/-1 = -10/-1
→ h = 10
<h3>
• Hence the value of h is 10 .</h3>
The answer is 2 you do what is in the parenthesis first. Which then gives you 10/5 and then you divide 10 by 5 and that is how you get 2.
Answer:
cosA = -
Step-by-step explanation:
Using the double angle identity
cos2A = 2cos²A - 1 , then
cosA = 2cos²( ) - 1 , that is
cosA = 2 × ( )² - 1
= 2 × - 1
= -
= -
Answer:
x 1 = -3
x2 = -3
y1 = 0
y2 = 5
The slope of that equation is infinite and the equation is a perfectly vertical line at x = -3.
So, the equation is x = -3.
