ryan rides his bicycle 5 miles in 3/4 hour. how many miles can he ride at the same rate in 1 hour? (in fractions)
Answer:
20/3
Step-by-step explanation:
If Ryan rides his bike 5 miles in 3/4 of an hour, then he rides 5/3 miles in 1/4 of a hour (divide both by 3). To get to a full hour from 1/4, you need to multiply it by 4. You must do the same for 5/3. 5/3*4 is equal to 20/3.

A concrete pillar has the shape of a cylinder. It has a radius of 3 meters and a height of 5 meters. If concrete costs $108 per cubic meter, how much did the concrete cost per pillar? Using 3.14 for pie
Answer:
Given:- r - 3 Meter
h - 5 Meter
rate - 108$ Per M³
Sol:
Volume of Cylindrical Concrete Pillar= V = πr²h
V = 3.14×3×3×5 (π = 3.14)
Volume ≈ 141.37
Cost of Concrete pillar = 108$/m³
Cost = 108 × 141.37
Cost of Making Cylindrical Concrete pillar= $15,267.96
Please help, if you’re correct I’ll mark you as brainiest!!!
Answer:
B. -7.5%
Step-by-step explanation:
Original cost: 50 * $20 = $1000
Value after 1 year: $925
percent change in 1 year = (925 - 1000)/1000 * 100%
percent change = -7.5%
Answer: B. -7.5%

At the time of her grandson's birth, a grandmother deposits $2000 in an account that pays 6.5% compounded monthly. What will be the value of the account at the child's twenty-first birthday, assuming that no other deposits or withdrawals are made during this period?
Answer:
$41, 863. 50
Step-by-step explanation:
$2000 - 6.5% = $1,993.50
$1,993.50 x 21 = $41, 863. 50
There are 7 girls and 3 boys in a class. Two students are to be
randomly chosen for a special project. What is the probability of
selecting a boy and a girl?
Answer:
7/15 is the probability of selecting a boy and a girl.
Step-by-step explanation:
Combination = nCr = n!/((n-r)!r!)
((7C1)(3C1))/(10C2)
= (7*3)/45
=21/45 = 7/15 the probability of selecting a boy and a girl.

(a) What is 0. 36 expressed as a fraction in simplest form?
(b) What is 0.36 expressed as a fraction in simplest form?
(c) What is 0.36 expressed as a fraction in simplest form?
Answer:
9/25
Step-by-step explanation:
3/10 + 6/100
3 is in the tenth place and 6 is in the hundredth place
rewrite the fractions as something over 100
so multiply the fraction 3/10 by 100; both numerator and denominator
this equals to 30/100 + 6/100
30 + 6 = 36/100
this can be simplified further by dividing 36 by 4 and dividing 100 by 4
this is equal to 9/25
I hope this helps

6. Barbara has $750 to deposit into two different savings accounts.
• Barbara will deposit $350 into accountl, which earns 4.5 % annual simple interest.
• She will deposit $400 into Account II, which earns 4 % % interest compounded annually.
Barbara will not make any additional deposits or withdrawals. Which amount is closest to
the sum of the balance of Account I and account II at the end of 3 years?
9514 1404 393
Answer:
(d) $850.45
Step-by-step explanation:
The balance in account I is given by ...
A = P(1 +rt) . . . . principal P invested at annual rate r for t years
A = 350(1 +0.045×3) = 397.25
__
The balance in account II is given by ...
A = P(1 +r)^t
A = 400(1 +0.0425)^3 ≈ 453.20
__
The total amount in the two accounts is
$397.25 +453.20 = $850.45

If a study determines the difference in average salary for subpopulations of people with blue eyes and people with brown eyes is NOT significant, then the populations of blue-eyed people and brown-eyed people are ________ different salaries.
Answer:
i dont know, sorry
Step-by-step explanation:
An ecologist is concerned that the number of toads that inhabit an area is declining. Since it is difficult to count the total number of toads exactly, a method that they use to detect the abundance of toads is to measure the time between mating calls during mating season. From a ten-year-old study, the mean time between mating calls was 1.2 seconds with a standard deviation of .3 seconds. Let X denote the random time between mating calls of these toads, and suppose X is normally distributed. The ecologist randomly selects a time between mating calls. Please compute the values up to three decimals ( ex: 0.571) Calculate the probability that the selected time is exactly 1.2 seconds
Answer:
0% probability that the selected time is exactly 1.2 seconds.
Step-by-step explanation:
Normal Probability Distribution:
Problems of normal distributions can be solved using the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the z-score of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the p-value, we get the probability that the value of the measure is greater than X.
The probability of a value being equals to x is 0 in the normal distribution.
From a ten-year-old study, the mean time between mating calls was 1.2 seconds with a standard deviation of .3 seconds.
This means that [tex]\mu = 1.2, \sigma = 0.3[/tex]
Calculate the probability that the selected time is exactly 1.2 seconds?
In the normal distribution, the probability of a finding an exact value is 0. So 0% probability that the selected time is exactly 1.2 seconds.
