Answer:

a. 14

b. 1

c. 2

Step-by-step explanation:

If there are 4 one point questions and 5 two point questions, then 5 multiplied by two is 10 and adding it to 4 is 14. The quiz would be 14 points total. If you scored 87.5% on the quiz then you would know that you got 12 of the questions correct and you would know that by finding 87.5% of 14 which the equation to do so would be 87.5/100= 0.875, then 0.875* 14= 12.25. If you round 12.25 to the nearest whole number then it's 12. And since you got all the 1 point questions right, then you must of gotten 1 two point question wrong.

I hope this helps!

Henry mowed 37 lawns out of 60 lawns. what percent of the lawns does henry stilln need to mow

Anarel [89]

Answer:

38 %

Step-by-step explanation:

1. Percent of lawns mowed

$\text{Percent} = \dfrac{\text{Lawns mowed}}{\text{No. of lawns}} \times 100 \% = \dfrac{37}{60} \times 100 \% = 62 \%}$

2. Percent of lawns unmowed

% Unmowed = 100 % - 62 % = 38 %

Henry still needs to mow 38 % of the lawns.
