Katie ran 4 miles at a rate of 1.1 miles slower than jasmine hiw many minutes did katie run if jasmine ran 5 miles at 8.4 minutes per mile
Answer:
Katie spent 29.2 minutes
Step-by-step explanation:
Given
Jasmine:
[tex]Distance = 5\ miles[/tex]
[tex]Rate = 8.4\ mins/mile[/tex]
Katie:
[tex]Distance = 4\ miles[/tex]
Rate = 1.1 mins/mile slower than Jasmine
Time spent by Jasmine:
[tex]Time = Distance * Rate[/tex]
[tex]Time = 5\ miles* 8.4mins/mile[/tex]
[tex]Time = 5* 8.4mins[/tex]
[tex]Time = 42\ mins[/tex]
Time spent by Katie:
[tex]Time = Distance * Rate[/tex]
We have that:
Rate = 1.1 mins/mile slower than Jasmine
So,
[tex]Rate = 8.4 - 1.1[/tex]
[tex]Rate = 7.3[/tex]
[tex]Time = 4 * 7.3[/tex]
[tex]Time = 29.2 \ mins[/tex]
u work for a lawn service and need to prepare fertilizer for the day. The directions state that you should mix four ounces of fertilizer for every ten gallons of water. The tank holds 50 gallons of water. You want to have a full tank to start the day’s work. How many ounces of fertilizer should you add to the tank
Answer:
you should add 20 ounces of fertilizer
20 ounces of fertilizer should be added to the water tank holding 50 gallons of water.
What is unitary method?The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.
Given are the directions to prepare a fertilizer for which you should mix four ounces of fertilizer for every ten gallons of water and the water tank containing water holds 50 gallons of water.
10 gallons of water require → 4 ounces of fertilizer
1 gallon of water will require → 4/10 ounces of fertilizer
50 gallons of water will require → (4/10) x 50 = 20 ounces of fertilizer
Therefore, 20 ounces of fertilizer should be added to the water tank holding 50 gallons of water.

Which of the following pairs of numbers have a greatest common factor of 6?
Select all that apply.
A 6 and 3
B 30 and 36
C 24 and 48
D 60 and 88
E 18 and 66
F 72 and 84
9514 1404 393
Answer:
B, E
Step-by-step explanation:
The greatest common factor can be found a number of ways. Easiest is to make use of your knowledge of multiplication tables and divisibility rules.
Here, the GCFs are ...
A 6 and 3 --- 3
B 30 and 36 --- 6
C 24 and 48 --- 24
D 60 and 88 --- 4
E 18 and 66 --- 6
F 72 and 84 --- 12
_____
Additional detail on finding the GCF
You can factor numbers to see which factors are common:
60 = 2^2 × 3 × 5
88 = 2^3 × 11 . . . . . . . so 2^2 = 4 is the GCF of 60 and 88
You can use the Euclidean algorithm:
Divide the larger by the smaller and keep the remainder; Replace the larger with the remainder and repeat. If the remainder is zero, the divisor is the GCF.
84/72 = 1 r 12
72/12 = 6 r 0 . . . . 12 is the GCF of 72 and 84
The set A = {1, 3, 5}. What is a larger set this might be a subset of?
Answer:
Step-by-step explanation:
A larger set that a particular set can be a subset of is a Universal set. A universal set is parent where all other sets are derived from.
For example, given a universal set U = {1,2,3,4,5}, a set A = {1, 3, 5} is said to be a subset of the set U because the elements of set B are contained in the Universal set U.
Also, sets like {1, 4,5} and {3,4,5} can also be regarded as the subset of U since all the elements of the sets can be found in the Universal set U. Hence the correct name of the set is a UNIVERSAL SET
So, the number of maximum subsets we can create from the given set is 8.
Subsets:The subsets of any set consists of all possible sets including its elements and the null set. Let us understand with the help of an example.
Example: Find all the subsets of set A = {1,2,3,4}
Solution: Given, A = {1,2,3,4}
Subsets =
The subsets of any set consisting of all possible sets including its elements and the null set. Let us understand with the help of an example.
Example: Find all the subsets of set A = {1,2,3,4}
{}
{1}, {2}, {3}, {4},
{1,2}, {1,3}, {1,4}, {2,3},{2,4}, {3,4},
{1,2,3}, {2,3,4}, {1,3,4}, {1,2,4}
{1,2,3,4}
So, the formula is [tex]2^n[/tex].
The given set is,
[tex]A = \{1, 3, 5\}[/tex]
Here the number of an element is 3.
So, the maximum number of subsets we can create is,

A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. The probability of at most 2 red cards is 0.5.
What is Binomial distribution?A common discrete distribution is used in statistics, as opposed to a continuous distribution is called a Binomial distribution. It is given by the formula,
P(x) = ⁿCₓ (pˣ) (q⁽ⁿ⁻ˣ⁾)
Where,
x is the number of successes needed,
n is the number of trials or sample size,
p is the probability of a single success, and
q is the probability of a single failure.
Using the given information the number of cards is 24 out of which 12 are red. Therefore, the probability of getting a red card is 0.5.
A) All red cards.
P(X=5) = ⁵C₅ (0.5⁵) (0.5⁰)
= 0.03125
B.) at least two red cards.
P(X≥2) = 1 - ⁵C₀ (0.5⁰) (0.5⁵) - ⁵C₁ (0.5¹) (0.5⁴)
= 0.8125
C.) At most 2 red cards.
P(X≤2) = ⁵C₀ (0.5⁰) (0.5⁵) + ⁵C₁ (0.5¹) (0.5⁴) + ⁵C₂ (0.5²) (0.5³)

Use the variable c for the unknown number.
Answer: 16 - C
Step-by-step explanation:
So basicly, what it is asking is to solve this problem. I would like to call it a puzzle because there is a missing part that we have to find. Let's get this started!
Here is the equaiton: 2 x (8 - C)
First, we will multiply 8 by 2.
8 x 2 = 16
Now the equation is: 16 - C
We don't know what C is, so this equation is as done as we can do it.
Substitute the given values into the given formula and solve for the unknown variable. If necessary, round to one decimal place

A tire shop counted 80 invoices at the end of the month. They charge $325 for a set of new tires and $50 for a set of used tires. The total dollar amount of the invoices was $6,750. Let x represent the number of sets of new tires and y represent the number of sets of used tires. Which system of equations represents the situation?
a. x+y=80
325z=50y + 6,750
b. z+y=80
325x=-50y+6750
c. x+y=80
325x=-50y-6750
d. x+y=80 -325z=-50y + 6,750
Answer:
[tex]x+y = 80\\325x+50y = 6, 750[/tex]
Step-by-step explanation:
Le x represents the set of new tires
Let y be the set of used tires
If a tire shop counted 80 invoices at the end of the month, then the equal that represents the total amount of invoices counted at the end of the month is:
[tex]x+y = 80 ............ 1[/tex]
If they charge $325 for a set of new tires, the total amount charged for new tires will be:
[tex]325 \times x \\325x[/tex]
If they charge $50 for a set of used tires, the total amount charged for used tires will be:
[tex]50 \times y\\50y[/tex]
If the total dollar amount of the invoices was $6,750, then the expression that models the amount generated on tickets will be:
[tex]325x+50y = 6,750 .............. 2[/tex]
Hence the system of equations represents the situation is:
[tex]x+y = 80\\325x+50y = 6, 750[/tex]
Answer:
x + y = 80
325x = -50y + 6,750

Answer:
249.5 (Note: I am not really sure of my answer so sorry)
Step-by-step explanation:
Let 'x' be the population in 1990.
The population in 2015 is 321.9 million.
The increase in x by 29% = 321.910^6
129% of x = 321.910^6
1.29x = 321.910^6
x = 321.910^6/1.29
x = 249.510^6
x = 249.5 million.

During bad weather, you should travel
the posted speed limit.
A. above
B. below
C. at exactly
D. around
Answer:
Below
Step-by-step explanation:
The reason why "lower than" would be the correct answer is because the DMV (Department of Motor Vehicles) requires that all drivers drive lower than the posted speed limit when the weather is not god.
The reason why you should travel lower than the posted speed limit is because it will keep you and others safe of the road. Bad weather can lead to things like less traction, less vision on the road, and etc.
When you drive slower than the posted speed limit during based weather, you're allowing your self more time to react if something happens, less likely to lose grip, and keeps you and others safe from any accidents.
Like they always say, you should never travel at a speed that's dangerous for the current road conditions.
