Answers
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

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
Answers
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

how do i rewrite 1/4 : 1/3 as a unite rate
Answers
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]
[tex]\dfrac{1}{4}:\dfrac{1}{3}=\dfrac{3}{4}[/tex]
[tex]\dfrac{1}{4}:\dfrac{1}{3}=0.75[/tex]
Therefore, the unit rate of the given ratio is 0.75.

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?
Answers
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

. Critique Reasoning Monica deposits $100 into
a savings account that pays a simple interest
rate of 3.4%. Paul deposits $200 into a savings
account that pays a simple interest rate of 2.2%.
Monica says that she will earn more interest in
one year because her interest rate is higher. Do
you agree? Justify your response.
Answers
Answer:
The answer would be no, Monica is wrong.
Step-by-step explanation:
By using the formula for simple interest; Time ( $ x Rate) = Interest
After a year, Monica would have gotten $40.80 in interest,
Paul would have gotten $81.60 in interest.
Because Paul deposited a higher amount of money than Monica, Paul earns more interest.
An architect designs a rectangular flower garden such that the width is exactly two-thirds of the length. If 340 feet of antique picket fencing are to be used to enclose
the garden, find the dimensions of the garden
Answers
Answer:
The dimensions of the garden is 102 feet by 68 feet
Step-by-step explanation:
Here, we want to get the width and length of the garden
The perimeter is represented by the length of the fencing
From the question;
w = 2l/3
The formula for the perimeter is;
P = 2(l + w)
Thus;
340 = 2(l + 2l/3)
170 = (l + 2l/3)
Multiply through by 3
510 = 3l + 2l
5l = 510
l = 102 feet
w = 2/3 * l
w = 2/3 * 102
w = 68 feet

Answers
Answer:
Option A
Step-by-step explanation:
[tex]R = (\frac{V_f-Vi}{V_i} )100[/tex]
where,
[tex]V_f[/tex] is the final value
[tex]V_i[/tex] if the initial value
R is the investors rate of return
so,
[tex]R = (\frac{V_f-Vi}{V_i} )100\\\\R=(\frac{1500-1700}{1700})100 \\\\R=(\frac{-200}{1700})100 \\\\R=-11.8\\[/tex]
so the investors rate of return is -11.8%
What is the 100th term of the sequence with a1 = 222 and d = -5?
PLEASE HELP VERY URGENTTTTTT!!!!!
Answers
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
