Terry is throwing a surprise party. She has invited 31 people. She is buying party favors that come in packages of 5. How many packages does Terry need to order so that she has enough for each guest to have one?
Answer:
Terry needs to buy 7 packages
Step-by-step explanation:
Terry has invited 31 people, meaning she needs 31 party favors
If they come in groups of five, we have to find how many packages(of 5) equal 31. Because 5 does not evenly multiply into 31, (it fits evenly inti 30) we have to add an extra package, meaning she will need 7 packages because 7×5 is 35, which is enough for each guest

Question 4a: Determine which car is traveling faster.
Speed: 110 feet per second
Speed 60 miles per hour
O
Black Car
Gray Car
Black Car
Gray Car
Answer:
110 ft per sec is faster than 60 mph
Step-by-step explanation:
110 ft per second is 396,000 feet per hour
396,000 feet equals 75 miles because there are 5,280 feet in one mile
so, 110 ft per sec is 75 miles per hr

Given that Lydia bought 2 ½ gallons of paint and used 1 ½ gallons of paint.
The fraction will be calculated as below,
2 ½ gallons can be expressed as 5/2
1 ½ gallons is the same as 3/2 the fraction used is the amount used over the total amount.
Fraction = 3 / 2 ÷ 5 / 2

we said that the ratio of girls to boys in the class was 2:9. if there were 90 boys in the 9th grade, how many girls are there
Answer:
20
Step-by-step explanation:
If the ratio of boys is 9 there are 90 boys. If 9=90 then 1= 10. 10 x 2 = 20
I hope this helps :0)
20 girls
Step-by-step explanation:
For every 9 boys there are 2 girls, so, if we have 90 boys, 9x10=90 and then since we have the 10 we use it to do 2x10 to get 20 girls
Some of the problems cities experienced as a result of rapid growth in the late 1800s included disease, crowded living spaces, and __________.
Answer:
poverty
Step-by-step explanation:
lack of workers makes no sense bcs the population was only increasing
limited recreational options don't make any sense either bcS that is not affected by population
and lack of transportation doesn't make any sense bcs it was the 1800's and people walked
Answer: B) Poverty
=====================================================
Explanation:
Unfortunately many people did not have much money to afford the basics such as a decent home and food to put on the table. Even if the person was working, they may be in a very dangerous job that provides little pay. An example could be a factory worker. So this is why choice B is the answer.
There were definitely plenty of able-bodied people, so there wasn't a shortage of workers. This allows us to rule out choice C. There also wasn't a lack of transportation since people either lived close and walked, or they had modes of transport such as rail or bike. Cars were starting to show up in the very late 1800s, but it wouldn't be until the early 1900s is when they became more commonplace. So we can rule out choice D.
Choice A can be ruled out since there were many recreation options such as going to the park or beach, or going to plays or classical music concerts, to name a few ways to have fun.

6 + 2 = 8
8/10 = 4/5
2. 9/20 + 5/20
9 + 5 = 14
14/20 = 7/10

On Saturday 1164 people saw movie at the up city theater on Sunday 1576 people saw the same movie there were a total of four movie screens with the same number of people in the audience about how many more people watched each screen on Sunday
Answer:
the number of more people watched each screen on sunday is 103
Step-by-step explanation:
The computation of the number of more people watched each screen on sunday is shown below:
= Sunday - saturday
= (1576 ÷ 4) - (1164 ÷ 4)
= 394 - 291
= 103 more people
hence, the number of more people watched each screen on sunday is 103

A right triangle has legs with lengths 61 cm and 60 cm. What is the length of the hypotenuse
Answer:
We gotta use Pythagorean theorem, fellas!
a^2 + b^2 = c^2
c^2 is the hypotenuse being squared.
a is a leg of a right triangle
b is another leg of a right triangle
------------------------------------------------------
we will use 61 for a
we will use 60 for b
a^2 + b^2 = c^2
61^2 + 60^2 = c^2
3721 + 3600 = c^2
7321 = c^2
[tex]\sqrt{7321}[/tex] = c (remember that c is hypotenuse)
c is rounded to 85.56 cm or 85.563 cm or 86 cm (depends on how the question wants the answer to look like)
ANSWER: 86 cm, 85.56 cm, or 85.563 cm

C - 9 and 10 years
D - 5 and 6 years
Answer:
1) A
2) A
3) C
4) D
Step-by-step explanation:
Exponential decay is for 1) because as the years pass, the depth decreases.
2) if it decreases by 2%, this means 100%-2%= 98%=0.98.
3) same as 2).
4) The equation for this situation can be represented with y=30(0.98)^x. when x is between 5 and 6, the depth of the lake is approximately 26.7 meters. So, it takes around 5 to 6 years for the depth of the lake to decrease to 26.7 meters.

Step-by-step explanation:
tan < ABC = 60/40
So m < ABC = 56.31 degrees.
This makes m < DBC = 56.31 / 2 = 28.15 degrees
tan 28.15 = DC / 40
DC = 40 tan 28.15
