In four rounds of a card game, you get scores of -1,-4,-8, and 10. What is your score ?

1 answer:

6 0

Your score would be 3. add -1, -4, and -8 together and get -13, then subtract 10 since 10 is positive and 13 is negative and get the answer 3. hope this made sense:)

The football coach is overseeing the installation of new goal posts on the football field. He is wondering if the goal posts are

Westkost [7]

Answer:

Correct option is D. No, since the ratios of the corresponding sides are not proportional.

Step-by-step explanation:

Please refer to the attached figure

Let height of coach represents by AB = 6 feet

And shadow of coach represents by BC = 4 feet

Let height of goal post represents by DE = x feet

And Shadow of goal post represents by EF = 12 feet.

Since measurement of shadows are at same time. therefore ratio of height of coach and height of goal post must be same as ratio of shadow of coach and shadow of goal post.

⇒ 6/x = 4/12

⇒x = 72/4 = 18 feet

So goal post is not at regular height , since expected height is 20 feet while actual height is 18 feet . And if we consider value of x as 20 feet instead of 18 feet , ratio of corresponding sides will not match.

Hence correct answer is D. No, since the ratios of the corresponding sides are not proportional.
