In the first event, the eighth graders are running a baton relay race with three other classmates. The team’s top speed for each leg is 56.81 seconds, 59.22 seconds, 57.39 seconds, and 60.11 seconds. Use the information to predict the team’s best time for the race.
Answer:
56.81 seconds is the team’s best time for the race
Step-by-step explanation:
Here, we want to give the team’s best time for the race
from the question, we should understand that the best times are the smallest in values since it is a race
The smallest time here is 56.81 seconds and thus that is the team’s best time for the race

What is the 100th term of the sequence with a1 = 222 and d = -5?
PLEASE HELP VERY URGENTTTTTT!!!!!
Answer: -273
Step-by-step explanation:
This is an arithmetic progression and the formula to find the nth term is given as:
= a + (n-1)d
Therefore, the 100th term will be:
= a + (n-1)d
= a + (100 - 1)d
= a + 99d
where a = 222
d = -5
Therefore, a + 99d = 222 + 99(-5)
= 222 + (-495)
= 222 - 495
= -273

how do i rewrite 1/4 : 1/3 as a unite rate
Given:
The ratio is
[tex]\dfrac{1}{4}:\dfrac{1}{3}[/tex]
To find:
The given ratio as unit rate.
Solution:
We have,
[tex]\dfrac{1}{4}:\dfrac{1}{3}[/tex]
Fraction form of given ratio is
[tex]\dfrac{1}{4}:\dfrac{1}{3}=\dfrac{\dfrac{1}{4}}{\dfrac{1}{3}}[/tex]
[tex]\dfrac{1}{4}:\dfrac{1}{3}=\dfrac{1}{4}\times \dfrac{3}{1}[/tex]

Can someone break down dividing/multiplying fractions?
Multiplying fractions
Ok, here's an example:
5/10 x 3/10
The numerator is the number on top. The denominator is the number on the bottom.
You multiply the numerators together to get 15.
Then, you multiply the denominators together to get 100.
Once you have 15/100, you would simplify it to get 3/20.
Dividing Fractions
Here's an example:
5/10 divided by 3/10
This is a little different.
Remember this: Keep, change, flip or KCF
So, keep the first fraction 5/10.
Flip the division sign into a multiplication sign.
Then, flip the 3/10 into 10/3
Right now we have 5/10 x 10/3
Now, use what you've learned from multiplying fraction and multiply the numerators together, than the denominators together.
So, you get 50/30.
Then you can simplify it into 5/3.

Answer:
10.625 seconds
Step-by-step explanation:
distance = speed · time
We want the total of all distances to be zero.
(-3.5)(90) +(2.2)(120) +(4.8)t = 0
-315 +264 +4.8t = 0 . . . . . simplify
-51 +4.8t = 0 . . . . . . . . . . . simplify more
-10.625 +t = 0 . . . . . . . . . .divide by 4.8
t = 10.625 . . . . . . . . . . . . . add 10.625
It will take the scientist 10.625 seconds to reach sea level.
Kaitlyn's older brother borrowed money for school he took out a loan that charges 6% simple interest he will end up paying 720 and interest after 6 years how much is Kaitlyn's brother borrow for school?
Answer: 2000
Step-by-step explanation:
Simple interest is calculated as:
(Principal × Rate × Time) / 100
We then slot the value into the formula. This would be:
720 = (P × 6 × 6)/100
720 × 100 = 36P
72000 = 36P
Principal = 72000/36
Principal = 2000

About 3/5th of the registered voters participated in 2016 election. California has 25 million registered voters. Find the number of registered voters who participated in 2016 election?
Given:
About 3/5th of the registered voters participated in 2016 election.
California has 25 million registered voters.
To find:
The number of registered voters who participated in 2016 election.
Solution:
We have,
Total number of registered voters = 25 million
According to the question,
[tex]\text{Registered voters who participated}=\dfrac{3}{5}\times \text{Total number of registered voters}[/tex]
Now,
[tex]\text{Registered voters who participated}=\dfrac{3}{5}\times 25[/tex]
[tex]\text{Registered voters who participated}=3\times 5[/tex]
[tex]\text{Registered voters who participated}=15[/tex]
Therefore, there are 15 millions of registered voters who participated in 2016 election.

The summer camps had a field trip from the campus to the fragrance house they traveled on average speed of 65 km in the first two hours after that they travel another average speed of 70 km is a distance between the campus and fragrance I was 364 km what was the total time for a field trip
Answer: 5.34 hours
Step-by-step explanation:
They traveled at an average speed of 65 km/h in the first 2 hours so the distance traveled was ;
= 65 * 2
= 130 km
The distance left was;
= 364 - 130
= 234 km
They travel at 70km per hour so time taken was;
= 234/70
= 3.34 hours
Total time = 2 + 3.34
= 5.34 hours

A large container of yogurt contains 36 ounces. How many cups of yogurt does the container hold?
Answer:
The container holds 4.5 cups of yogurt
Step-by-step explanation:
Here, given the number of ounces of yogurt in a container, we want to calculate the number of cups the container can hold
Mathematically, we need a conversion factor
1 cup contains 8 ounces
but here
x cups contains 36 ounces
8 * x= 36 * 1
8x = 36
x = 36/8
x = 4.5
The number 2160 can be expressed as 2a x 3b x 5 find the value of a and b
Answer:
Step-by-step explanation:
2160 = 2a * 3b * 5
2160/5 =2a*3b
432=6*a*b
432/6 = a*b
72 = a * b
72 = 8 * 9
a=8
b=9
The number 2160 can be expressed as 2a x 3b x 5 , where a = 8 and b = 9
Given data:
To find the values of a and b in the expression 2^a * 3^b * 5,
2160 = 2a * 3b * 5
Divide by 5 on both sides:
2160/5 =2a*3b
432=6*a*b
Divide by 6 on both sides:
432/6 = a*b
72 = a * b
The values of a and b can be determined as:
72 = 8 * 9
a = 8
b = 9
Hence, in the expression 2a x 3b x 5 = 2160, the value of a is 8 and the value of b is 9.
