Khadija answered 174 questions correctly on her multiple choice science final and earned a grade of 87%. How many total questions were on the final exam
The total number of questions is an illustration of proportions
The total number of questions is 200
How to determine the total questions?From the question, we have:
Grade = 87%
Questions answered = 174
Represent the total questions with x.
So, the total question is calculated as:
174 = 87% * x
Make x the subject
x = 174/87%
Evaluate the quotient
x = 200
Hence, the total number of questions is 200

You have 6 pints of glaze. It takes 7/8 of a pint to glaze a bowl and 9/16 of a pint to glaze a plate. a. How many bowls could you glaze? How many plates could you glaze? You could glaze bowls. You could glaze plates. b. You want to glaze 5 bowls, and then use the rest for plates. How many plates can you glaze? How much glaze will be left over? You could glaze plates and will have pints of glaze left over. c. How many of each object could you glaze so that there is no glaze left over? Explain how you found your answer. You could glaze bowls and plates. The bowls use pints of glaze and the plates use pints of glaze, for a total of 6 pints of glaze.
Answer:
a.
How many bowls could you glaze?
we can only glaze 6 bowls
How many plates could you 10 plates
b. You want to glaze 5 bowls, and then use the rest for plates.
How many plates can you glaze?
Hence we can only glaze 2 plates
How much glaze will be left over?
8/9
c. How many of each object could you glaze so that there is no glaze left over?
= 4 4/23 bowls and 4 4/23 plates
Step-by-step explanation:
You have 6 pints of glaze. It takes 7/8 of a pint to glaze a bowl and 9/16 of a pint to glaze a plate.
a.
How many bowls could you glaze?
It takes 7/8 of a pint to glaze a bowl
We have 6 pint
7/8 pint = 1 bowl
6 pints =
6 pints/ 7/8
= 6 × 8/7
= 48/7
= 6.8571428571 bowls
We can't glaze decimal of a bowl, hence, we can only glaze 6 bowls
How many plates could you glaze?9/16 of a pint to glaze a plate.
9/16 pint = 1 bowl
6 pints =
6 pints/ 9/16
= 6 × 16/9
= 10.666666667 plates
We can't glaze decimal of a plate, hence, hence can only glaze 10 plates
b. You want to glaze 5 bowls, and then use the rest for plates.
1 bowl = 7/8 pints
5 bowls =
5 × 7/8pints
= 4 3/8 pints of glaze would be used for bowls
How many plates can you glaze?
The rest is for plates, hence:
6 pints - 4 3/8
1 5/8 pints of glaze would be left over to glaze plates.
Hence if
9/16 pints = 1 plate
1 5/8 pints =
= 2 8/9
Hence we can only glaze 2 plates
How much glaze will be left over?
8/9
You could glaze plates and will have pints of glaze left over.
c. How many of each object could you glaze so that there is no glaze left over?
We have 6 pints of glaze
7/8 x + 9/16 × x = 6 pints
= 4 4/23 bowls and 4 4/23 plates

The amount of the pizza he ate will be 9 / 40.
What is Algebra?Algebra is the study of graphic formulas, while logic is the interpretation among those signs.
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.
There are ten pieces of pizza.
Anthony ate 1/8 of the pizza for dinner.
Then the amount of pizza left will be
⇒ 1 – 1/8
⇒ (8 – 1) / 8
⇒ 7/8
He ate 3/10 for a bedtime snack.
Then the amount of the pizza will be
⇒ 7/8 – 1/10
⇒ 31/40
The pizza has he eaten in all.
Then the amount of the pizza he ate will be
⇒ 1 – 31/40
⇒ 9 / 40
Then the amount of the pizza he ate will be 9 / 40.
