9 is the constant because if you were to factor it the zeroes would be 3
Answer:
3/4th of a mile jogs in 8 1/2 minutes.
Let us convert 8 1/2 into improper fraction first, 8 1/2 = (8*2+1)/2 = 17/2 minutes.
In order to find the number of minutes required to to cover 1 mile of distance, we need to divide given number of minutes by given number of miles.
Therefore, number of minutes does it take him to jog 1 mile 17/2 ÷3/4
Let us convert division sign into multiplication.
The second fraction will get flip, we get
17/2 × 4/3 = 17 x 2/3 = 34/3
Converting 34/3 into mixed fractions, we get quotient =11 and remainder =1.
Therefore, 34/3 = 11 1/3.
Therefore, 11 1/3 minutes does it take him to jog 1 mile.
Hope this helps!

Answer: 79°
Explanation:
1) Law of cosines:
In a triangle with sides a, b, c whose opposite angles are, respectively, A, B and C, the law of cosines states:
c² = a² + b² - 2 a×b×cos (C)
2) In the triangle of the figure you have
c = 9
C = X
a = 6
b = 8
⇒ 9² = 6² + 8² - 2(6)(8) cos(X)
⇒ 81 = 36 + 64 - 96cos(X)
⇒ 96cos(X) = 36 + 64 - 81 = 19
⇒ cos(X) = 19 / 96
⇒ X = arccos(19/26) = 78.6° ≈ 79°
Answer:
(2-6)(10) plus 3 to the power of 2, is <u>-31</u>.
Explanation:
Three to the power of two plus parenthesis two minus six parenthesis parenthesis ten. This is the same as the sum or addition of 3 times 3(3 times itself two times), and 2 minus 6 times 10.
This expression can be represented by (3^2) + (2-6)(10) which is (3 × 3) + (-4 × 10) which is 9 + -40 which simplifies to -31
