Answer:
a) and e)
Step-by-step explanation:
7 * 1/2 = 3.5
3.5 / 2 = 1.75
? = 1.75
a) 2 * 1.75 = 7 * 1/2 (correct!)
b) 7 * 1/2 * 1.75 = 2 (wrong!)
c) 2 * 7 * 1/2 = 1.75 (wrong!)
d) 1.75 * 7 * 1/2 = 2 (wrong! this is the b) backwards)
e) 1.75 * 2 = 7 * 1/2 (correct! this is the a) backwards)
Answer:
30450 is the answer.
Step-by-step explanation:
Given number is 
.
We need to write it as an ordinate number.
It is 3.0450 times 10 to the power 4.
It would mean that,
Hence, the required answer is 30450.
Answer:
(3, -8)
Step-by-step explanation:
-3*3 - 3y = 15
-9 -3y = 15
3y = -24
y = -8
Answer:
x = 16
Step-by-step explanation:
(whole secant) x (external part) = (tangent)^2
(x+2) * 2 = 6^2
2(x+2) = 36
Divide each side by 2
x+2 = 18
Subtract 2
x+2-2 = 18-2
x = 16
True we would get a different solution
