marcia is typing her report for history class. She can type 4 pages in 45 minutes. At that rate, how many pages does she type per hour? Round to the nearest hundredth.
Answer:
5.34 pages/h
Step-by-step explanation:
4/45 = p/60
p ≈ 5.34
Answer:
Step-by-step explanation:
3/4 of an hour is the same as 0.75
Write a proportion.
4 (pages)/0.75 (hours)=p(pages)/1 hour
Cross multiply and divide
(4x1)÷0.75=5.33 (rounded to the nearest hundred)
p=5.33
Marcia can type 5.33 pages per hour.

On which test does Zane have the highest unit rate?
Answer:
Test A: 40 words per minute
Test B: 54 words per minute
Test C: 44 words per minute
Test B has the highest unit rate

Answer:
B. 1.5 cups
Step-by-step explanation:

each person gets 0.75 each
Since 2 people chose not to drink the juice. the left overs would be 0.75*2
0.75*2=1.5
Math!!!! Fined the area of the triangle
Answer:
Area = 40 cm²
Step-by-step explanation:
Area of triangle is derived by the formula,
Area = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
Length of Base = 8 cm
Height of the triangle = 10 cm
Therefore, area of the given triangle = [tex]\frac{1}{2}(8)(10)[/tex]
= 40 cm²

A baker uses 3/4 teaspoon cinnamon for every 2/3 can of pumpkin when making pumpkin muffins. How much cinnamon does the baker need for each can of pumpkin?
Answer:
9/8 teaspoon
Step-by-step explanation:
The original ratio is 0.75:0.66 (x:y). We need to find x when y = 1.
0.66*1.5 = 1
So, if the original y was multiplied by 1.5 to get 1 (which we need) then we can multiply the original x to get our answer.
0.75*1.5 = 1.125
Convert into fractional form:
1.125 = 9/8
Your answer is 9/8 teaspoon of cinnamon per one can of muffins.
Hope this helps. Have a nice day. Oh, and one more thing. Surprised I'm not stealing points?

Zack and Dave each bought some coins from jerry online. Dave bought 5 more coins than Zack bought
C. Explain why it’s not necessary to know how many coins Zack bought to determine how much more Dave paid than Zack paid
Answer & Step-by-step explanation:
number of Dave's coins = number of Zack's coins + 5
The question is asking to find the difference in prices paid (thus "more"), completely unrelated to the number of coins Zack bought as these two numbers are independent of one another. The difference in price can be found by simply multiplying the cost of one coin by 5.

Write an equation that models this situation. At a sports banquet, 8 guests are seated at each of the 15 available tables. How many guests (x) are seated at the tables?
Answer: The equation that models this situation is:
x = 15 × 8 or x ÷ 8 = 15
Step-by-step explanation:
Let 'x' be the total number of guests who are seated at the tables.
If have to determine how many guests (x) are seated at the tables, all we need is to multiply the 15 with 8.
so the equation becomes
x = 15 × 8 or x ÷ 8 = 15
Therefore, the equation that models this situation is:
x = 15 × 8 or x ÷ 8 = 15
hope this helps good luck
Which value of x makes the following equation true? 5 x + 3 x = 72 x
Answer:
I might be wrong
Step-by-step explanation:
x= 9? sorry if that's wrong
Answer:
x =9
Step-by-step explanation:
take off the x
add 5+3=8
divide 72 by 8
answer is 9 so x=9
you can double check by multiplying 5×9 then 3×9 then adding your answers together to give you 72
What would be the first step to solve this equation x - 5 (x-1) = x - (2x- 3 )
Bob can complete his Math homework in
2.5 hours, but if he works with Joe they can finish in 1.5 hours. How long would it take Joe to finish his homework on his own?
Answer:
3.75 hours
Step-by-step explanation:
Bob completes his homework in 2.5 hours.
In 1 hour, he completes 1/2.5 of his homework.
Joe completes his homework in x hours.
In 1 hour, he completes 1/x of his homework.
Together, they complete the homework in 1.5 hours.
In 1 hour, they do 1/1.5 of the homework.
1/2.5 + 1/x = 1/1.5
Convert the decimal numbers in the numerators into fractions.
1/(5/2) + 1/x = 1/(3/2)
2/5 + 1/x = 2/3
Multiply both sides by the LCD, 15x.
6x + 15 = 10x
-4x = -15
x = 3.75
Answer: 3.75 hours

A rectangle has an area of 48 square units and a perimeter of 32 units. What are its dimensions?
At the end of the month, a restaurant manager used the total food sales for the month and the total number of customers for the month to calculate the mean about spent per customer during that month was $12.59. Is this value a statistical or a parameter? Explain.
Answer:
Step-by-step explanation:
It is a parameter, I think. The population is limited to all of the restaurant's customers. Presumably they don't come in to look at the waitresses -- although that might happen. They are there for coffee donuts or a meal, so they are spending money, that's what all of them have in common.
So the population is very confined and very well defined.
The owner is finding a mean. Anything like this is a parameter which defines some aspect of the population.
What’s the equation of the line in fully simplified slope-intercept form
Answer:
y= -x - 8
Step-by-step explanation:
To write an equation in slope-intercept form, we naturally need both the slope and the y-intercept. Here, our y-intercept is -8, and our slope is -1. The general form of a line in slope intercept form is y = mx + b, where m is the slope and b is the y intercept. Using our values of m = -1 and b = -8 then gives us the equation y = -x - 8.

t a school. number of boys/number if girls =9/7. there are 116 more boys than girls. work out the total number of students at the school
Answer:
928
Step-by-step explanation:
Ratio of boys to girls is 9:7, so boys are 9/(9+7) = 9/16 of the total, and the girls are 7/16
the difference is 9/16-7/16 = 2/16 = 1/8, so
x * 1/8 = 116
x = 116*8 = 928
