Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 45 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 23 of the number of part 2 questions. What was the total number of questions on Stephanie's exam?
Given :
Stephanie took a science exam that had two parts. Part 1: She got 16 questions correct, which was 4/5 of the number of part 1 questions. Part 2: She got 16 questions correct, which was 2/3 of the number of part 2 questions.
To Find :
The total number of questions on Stephanie's exam.
Solution :
Let, number of questions in Part 1 is x :
[tex]16=\dfrac{4}{5}x\\\\x=20[/tex]
Let, number of questions in Part 2 is y :
[tex]16=\dfrac{2}{3}y\\\\y=24[/tex]
Therefore, total number of questions on Stephanie's exam are 20 + 40 = 60.
Hence, this is the required solution.
Diana wanted to make peanut brittle for a holiday party, so she bought a 16.5-ounce jar of peanuts at the grocery store. She used 3 5 of the peanuts to make peanut brittle. The next week, she split the remaining peanuts into 3 bags of trail mix for a hike with friends. How many ounces of peanuts did Diana put in each bag of trail mix?
Answer:
2.2 ounces.
Step-by-step explanation:
Quantity of peanuts Diana bought = 16.5 ounces
Quantity used for peanut brittle = 3/5
Hence:
3/5 × 16.5
= 9.9 ounces was used for peanut brittle.
The amount left =
16.5 ounces - 9.9 ounces
= 6.6 ounces.
We are told that: the next week, she split the remaining peanuts into 3 bags of trail mix for a hike with friends.
The ounces of peanuts she put in each bag of trail mix is calculated as:
6.6 ounces ÷ 3 bags
= 2.2 ounces.

AB || CD and AC is oblique ;
So : Angle ( BAC ) = Angle ( DCA )
_________________________________
∆ ABC - ∆ ACD :
(1) AB = CD
(2) Angle ( BAC ) = Angle ( DCA )

Find the value of x.
Area of rectangle = 36
▅ х
x + 5
The value of x is 4, which is determined by the quadratic equation.
What is the area of the rectangle?The area of a rectangle is defined as the product of the length and width.
The rectangle of a rectangle = L × W
Where W is the width of the rectangle and L is the length of the rectangle
We have been given that area of the rectangle = 36
Area of rectangle = width of the rectangle × length of the rectangle
Here the width of the rectangle = x
And length of the rectangle = x + 5
The rectangle of a rectangle = x × (x + 5)
36 = x² + 5x
x² + 5x - 36 = 0
x² + 9x - 4x - 36 = 0
(x + 9)(x - 4) = 0
x = -9 and x = 4
Take the value of x = 4 and the negative value is neglected because the dimension can't be negative.
Therefore, the value of x is 4.

Solve the equations 7(2x+6)=1
Answer:
Step-by-step explanation:
B
Answer:
x = - [tex]\frac{41}{14}[/tex]
Step-by-step explanation:
Given
7(2x + 6) = 1 ← distribute parenthesis on left side
14x + 42 = 1 ( subtract 42 from both sides )
14x = - 41 ( divide both sides by 14 )
x = - [tex]\frac{41}{14}[/tex]

At the beginning of the season, a golf coach buys 118 sleeves of golf balls. Each sleeve costs $8

O
Answer:
A
Step-by-step explanation:
The coach will most likely count this as an expense and will want to overestimate so that he is certain to have all the golf balls for his lessons. If he underestimates, he will not be able to have all his balls.
A. It is better to overestimate to make sure the coach has enough money to buy the golf balls.
What is over and under estimating ?Over estimating is when we set a higher amount than we need in case of price increase and the item is a must buy.
Underestimating when we set a lower amount than needed when money is of more concern and the item is not a must buy.
According to the given question At the beginning of the season, a golf coach buys 118 sleeves of golf balls. Each sleeve costs $8.
It is always better to overestimate and if some amount remains then it can be used later.
So, It is better to overestimate to make sure the coach has enough money to buy the golf balls to continue his lessons without any interruption underestimating will lead to less golf balls and interrupted golf sessions.

bcz 5×7=35
6×7=42
7×7=49
Answer:
B
Step-by-step explanation:
Given that the triangles are similar then the ratios of corresponding sides are equal, that is
[tex]\frac{AB}{DE}[/tex] = [tex]\frac{BC}{EF}[/tex] , substitute values
[tex]\frac{35}{5}[/tex] = [tex]\frac{42}{x}[/tex] ( cross- multiply )
35x = 210 ( divide both sides by 35 )

Charlie wants to order lunch for his friends. He'll order sandwiches and a $2 kid's meal for his little brother. Charlie has $32. How much can he spend on each sandwich if they are all the same price? "choose two answers" A) Inequality: 2x+6<32. B)Answer $5 or less. C) Inequality 6x+2 ≤32.D)Answer $13or less. E) Inequality 2x+6≤32. F) Inequality 6x+2≥32
So, obviously, since one of the prices is given, which is $2.00 for the kid's meal, then you need to subtract that from his $32.00 total to know what number you need to divide into the 6 sandwiches. So, so far you have $30.00. If you divide $30.00 by the 6 sandwiches, you will find out he could only spend $5.00 per sandwich. So basically, you got the expression of (32 -2) / 6 in order to find out that your answer is $5.00. Looking at you answer choices, I can see right away that D is correct. For the inequality, I can see that B would be the correct answer for this problem because he can't go over budget. So, your answers are B and D.

PLEASE ANSWER! What is the Average rate of change of (-5,0) and (-2,6)
Answer:
3/4
hope this helped :)
Answer:
Hello!!! Princess Sakura here ^^
Step-by-step explanation:
The average rate of change is just like how you would find the slope so that's what I'm going to do.
[tex]m=\frac{6-0}{-2--5}[/tex]
I will use this equation to find it...
[tex]m=\frac{6-0}{-2--5}=\frac{6}{3} =2[/tex]
So the rate of change is 2.
Yesterday, Grace drove 38 1/2 miles. She used 1 1/4 gallons of gasoline. What is the unit rate for miles per gallon?
Answer:
The unit rate for miles per gallon is 30 3/5
miles per gallon
Step-by-step explanation:
To get the unit rate for miles per gallon, we simply divide the number of moles by the amount of gallons
Number of miles is 38 1/2 which is 77/2 miles
Number of gallons = 1 1/4 = 5/4
So unit rate will be;
77/2 divided by 5/4
= 77/2 * 4/5 = 154/5 = 30 3/5 miles per gallon
