Answer:

No. This is not a valid claim

Step-by-step explanation:

First we sum up the total snowfall for the 3 days as:

Monday= 15 inches

Tuesday=4.5 inches

Wednesday=6.75 inches

Total= 26.25 inches

As it is understood that there are 12 inches per foot. So we can simply multiply the number of inches it snowed during the last three days by this factor to find out.

26.25  in ×  1ft /12in ⇒

i.e. 26.25 x 1ft/12

which is 26.25ft / 12

that concludes 2.1875 ft

so it is not close to the forecaster said over 2 1/2 ft

Add them all up:

15 + 4 1/2 + 6 3/4 = 26 1/4 in.

2 ft equals 24 in.

2 1/2 ft = 30 in.

Yes, it is a valid claim.

The supplement of an angle is three times the measure of the angle.
stira [4]

Answer: The angle equals  45 ∘  and the supplement is  135 ∘

Explanation:

Since the supplement is three times the angle, we can say    s  =  3 a

Since we know the supplement is  

180 − a , we can plug that in.

180 - a = 3a

180  = 4 a  (add  a  to both sides)

45  =  a  (divide both sides by  4)

Since we know the angle now, all we have to do is multiply it times  3  to find the supplement.

45  ×  3  =  135

X= -1/5; f(x) = (25/2)x + (-91/2) =
Diano4ka-milaya [45]

Answer:

Write the problem as a mathematical expression.

X=−1/5; f(x)=(25/2)x+(−91/2)

Replace the variable x with x=−1/5 in the expression.

f(−1/5)=(25/2)(−1/5)−91/2

Simplify the result.

−48
