Step-by-step explanation:
The percent decrease in the time taken by Celesta is 33.33%.
What is Percentage?Percentage of a number is the parts per 100. Or percentage of a number can be calculated by dividing the number with the whole with respect to which we are finding the percentage of the number and then multiply with 100.
Percentage is a dimensionless number because percentage is not measured by any units.
Percentage decrease can be calculated by the formula,
Percentage Decrease = [(Original value - New value) / Original value] × 100
Time that Celesta used to spend on the phone a day = 90 minutes
Original value = 90
Now, celesta spends 60 minutes a day
New value = 60
Percentage decrease = [(90 - 60) / 90] × 100
= [30 / 90] × 100
= [1 / 3] × 100
= 33.33 %
Hence the percent decrease in the time taken by Celesta in a day is 33.33%.

A geometric sequence starts with 10, 5, . . . Explain how you would calculate the value of the 100th term.
Answer:
The 100th term will be;
10(0.5)^99
Step-by-step explanation:
Firstly, we need the common difference and the first term
The first term is 10
The common difference is 5/10 = 1/2
Now, the formula for the nth term of a geometric sequence is;
ar^n-1
So, for the nth term, we have;
ar^(100-1)
= ar^99
So we have
10(1/2)^99

Mr. Chen drives 26 miles to work every day. He drives the same distance to get back home. How many miles does he drive during a 5-day work week
Answer:
260 miles
Step-by-step explanation:
Given that,
Total distance driven by Mr. Chen everyday = 26 miles
He drives the same distance to get back home.
It means total distance driven by Mr. Chen to go and come back = 2(26) = 52 miles
We need to find how many miles does he drive during a 5-day work week.
Total distance = 5×52
= 260 miles
Hence, he will drive 260 miles during a 5 day work week.

A number cube is rolled twice. What is the probability of getting a 6 on the first roll,
then a number less than 5 on the second roll?
A. 5/36
B. 1/9
C. 2/3
D. 1/36
Answer:
b. 1/9
Step-by-step explanation:
1. 1/6 is the probability of rolling 6
2. 4/6 is the probability of rolling less than 5
3. Multiply them: [tex]\frac{1}{6} x\frac{2}{3}[/tex]
4. Answer: 1/9
The probability of getting a 6 on the first roll, then a number less than 5 on the second roll should be option b.
Calculation of the probability:since
1/6 should be considered as the probability of rolling 6
And, 4/6 is the probability of rolling less than 5
So [tex]= 1\div 6 \times 2\div 3[/tex]
= 1/9
Hence, the option b is correct.

At a party there were four large submarine sandwiches, all the same size. During the party, 2/3 of the chicken sandwhich, 3/4 of the tuna sandwhich, 7/12 of the roast beast and 5/6 of the veggie sandwhich were eaten. Which sandwhich had the least amount left?
Answer:
The answer is the Veggie Sandwich
Step-by-step explanation:
Given that there are four large submarine Sandwiches in a party and all of them are of the same size.
Some parts of each of them were eaten during the party. We are to find the Sandwich that has the least amount left.
The fractions of the Chicken Sandwich(C), Tuna Sandwich(T), Roast beef Sandwich(R) and the Veggie Sandwich(V) that were eaten during the party are given by
Therefore, the fractions of the Sandwiches that left will be
Out of the four fractions, V' is the smallest, so the Veggie Sandwich has the least amount left.

A unicycle tire can travel 7.85 ft. in on revolution. What is the area of the unicycle tire? Round answer to the nearest tenth.
Answer:
The answer would be 0.06
Step-by-step explanation:
Answer:
4.9ft^2
Step-by-step explanation:
7.85 ft is the circumference of the tire (circle), so [tex]\pi[/tex]d = 7.85.
7.85/[tex]\pi\\[/tex] = 2.5, the diameter is 2.5, so the radius is 1.25.
[tex]\pi[/tex]r^2 is the formula for the area, so [tex]\pi[/tex]*1.25^2 = 1.5625[tex]\pi[/tex], which is 4.906, which rounded to the tenth is 4.9.

Given:
Perimeter of a parallelogram = 64 cm
Length = 3 times larger than the width
To find:
The length of the parallelogram.
Solution:
We know that, the perimeter of the parallelogram is:
[tex]P=2(l+w)[/tex]
Where, l is length and w is width of the parallelogram.
We have, l = 3w and P=64.
So,
[tex]64=2(3w+w)[/tex]
[tex]64=2(4w)[/tex]
[tex]64=8w[/tex]
Divide both sides by 8.
[tex]8=w[/tex]
Now,
[tex]l=3w[/tex]
[tex]l=3(8)[/tex]
[tex]l=24[/tex]
Therefore, the length of the parallelogram is 24 cm.
