Answer:
it is 7.1
Step-by-step explanation:
how i got my answer is because jasmine ran 8.2 minute per mile
and Katie was 1.1 slower than jasmine so we will have to subtract like this
8.2
- 1.1
7.1 so katie ran 7.1 minutes per mile
If Katie ran at a rate that was 1.1 minutes per mile slower than Jasmine's.She takes 29.2 minutes to run.
What is the rate of change?It is defined as the change in values of a dependent variable with respect to the independent variables. the rate of change of distance with respect to time denotes the speed i.e. m/sec.
It is given that, Katie ran 4 miles. She ran at a rate that was 1.1 minutes per mile slower than Jasmine.
Time is taken by Katie for the given rate,
T = 5 miles × 8.4 mins / mile
T = 42 minute
The rate for Jasmine,
r = 8.4 - 1.1
r=7.3
The time for which Katie run,
t = 4 × 7.3
t = 29.2 minute
Thus, if Katie ran at a rate that was 1.1 minutes per mile slower than Jasmine's. She takes 29.2 minutes to run.
The question is incomplete.
The complete question is"Katie ran 4 miles at a rate of 1.1 miles slower than jasmine how many minutes did Katie run if jasmine ran 5 miles at 8.4 minutes per mile"

I cannot
Answer:
A) There is a rational relationship, B) Given ratio is not an integer.
Step-by-step explanation:
A) Is the relationship in Part A rational or irrational? Justifty your answer.
From Mathematics we remember that a rational number can formed by dividing a natural number by another natural number. Since Kara and Nathan had two natural numbers {32, 40} as their times of participation in the maze race, ratio between those times can be considered a rational number.
Hence, there is a rational relationship.
B) Can the times for each be written as integers?
The times represents the ratio of the upper number (40) to the lower number (32), the "times" can be written as integer if and only if denominator is equal to 1 after simplifying the ratio. That is:
[tex]x = \frac{40}{32}[/tex]
[tex]x = \frac{20}{16}[/tex]
[tex]x = \frac{10}{8}[/tex]
[tex]x = \frac{5}{4}[/tex]
In consequence, this ratio does not represent an integer. ([tex]1.25=\frac{5}{4}[/tex])

A local bank charges $9 per month plus 24 per check. The credit union charges $7 per month plus 4e per chock. How many checks should be written each month to make the credit union a bottor deal?
The credit union is a better deal when writing or fower checks per month
This question was not properly written
Correct Question
A local bank charges $9 per month plus 2c per check. The credit union charges $7 per month plus 4cper check. How many checks should be written each month to make the credit union a better deal?
The credit union is a better deal when writing fewer checks per month
Answer:
Writing between 0 to 99 checks makes the credit union a better deal.
Step-by-step explanation:
Let the number of checks be represented by x
Note, 1 cent = $0.01
A local bank charges $9 per month plus 2c per check.
2c = $0.02
$9 + 0.02× x
= 9 + 0.02x
The credit union charges $7 per month plus 4c per check.
4c = $0.04
= $7 + 0.04 × x
= 7 + 0.04x
The credit union is a better deal when writing fewer checks per month
Hence:
Credit union < Local bank
7 + 0.04x < 9 + 0.02x
Collect like terms
0.04x - 0.02x < 9 - 7
0.02x < 2
x < 2/0.02
x < 100 checks
Hence, writing less than 100 checks (i.e writing between 0 to 99 checks) makes the credit union a better deal.

triangle DEF is a right triangle and the of angle D is 28° what are the measures of the other two angles if the measures of angle E is greater than the measure of angle F
Answer:
A possiable answer to solve this could be E is 86 and F is 66
Step-by-step explanation:
All triangles have a 180 degree to them. I just subtracted 28 from 180. Diveded that by 2 then gave one ten degrees more and the other has ten degrees less
The measure of the angle E will be 90° and the measure of the angle F will be 62°.
What is the triangle?A triangle is a three-sided polygon with three angles. The angles of the triangle add up to 180 degrees.
The triangle DEF is a right triangle and the of angle D is 28°.
In a right-angle triangle, one angle will be 90°.
If the measure of angle E is greater than the measure of angle F. Then the angle E will be 90°. Then the measure of the angle F will be given as,
We know that angle D and angle F are complementary. Then the equation is given as,
∠F + ∠D = 90°
∠F + 28° = 90°
∠F = 62°
The measure of the angle E will be 90° and the measure of the angle F will be 62°.

what are the x and y intercepts
Answer:
The y intercept is (0,2) and the x intercept is (5,0)
Step-by-step explanation:
Find the y-intercept by letting x = 0
2(0) + 5y = 10
5y = 10
y = 2 Therefore, the y-intercept is (0, 2)
Find the x-intercept by letting y = 0
2x + 5(0) = 10
2x = 10
x = 5 Therefore, the x-intercept is (5, 0)

The two decisions that perform the hypothesis test includes fail to deny the null hypothesis, and deny the null hypothesis.
Hypothesis testing refers to the testing that can give access to the reliability of the hypothesis via sample data.
There are two types of decisions that are considered to be wrong while performing the hypothesis test is:
In the case when the hypothesis is true but i.e. rejected. This is known as a type I error.In the case when the hypothesis is false, but it is failed to reject it. This is known as a type II error.So, the decisions that should not be considered while performing the hypothesis test is:
Acceptance of the alternative hypothesis.Acceptance of the null hypothesis.Fail to deny the alternative hypothesis.Deny the alternative hypothesis.Making of type I error.Making of type II error.Therefore we can conclude that options D and option E are considered from performing a hypothesis test.

The cost of parking a motor home in a state park includes a one time fee of $180, plus a daily rate of $55 per day. Anthony prepaid for his stay and paid the state park commission a fee of $565. This paid for the one time fee as well as for a number of days. How many days of parking did Anthony pay for? Group of answer choices
Answer:
Anthony paid for 7 days of parking.
Step-by-step explanation:
From the information given, the cost of parking a motor home in a state park would be equal to the one time fee plus the result of multiplying the daily rate for the number of days:
c=180+55x, where c is the cost of parking the motor home and x is the number of days.
Now, you can replace c with 565 that is the amount Anthony prepaid and you can solve for x to be able to find the number of days he paid for:
565=180+55x
565-180=55x
385=55x
x=385/55
x=7
According to this, Anthony paid for 7 days of parking.

[tex]y = \frac{1}{3}x +2[/tex]
Step-by-step explanation:
Given
Equation:
[tex]y = \frac{1}{3}x + 4[/tex]
[tex]Point: (-3,1)[/tex]
Required
Determine the equation of the point parallel to the given equation
First, we need to determine the slope of: [tex]y = \frac{1}{3}x + 4[/tex] using
[tex]y = mx + b[/tex]
Where m represents slope.
By comparison
[tex]m = \frac{1}{3}[/tex]
The equation of the point is calculated as thus:
[tex]y - y_1 = m(x - x_1)[/tex]
Where [tex](x_1,y_1) = (-3,1)[/tex]
So, we have:
[tex]y - y_1 = m(x - x_1)[/tex]
[tex]y - 1 = \frac{1}{3}(x - (-3))[/tex]
[tex]y - 1 = \frac{1}{3}(x +3)[/tex]
[tex]y - 1 = \frac{1}{3}x +1[/tex]
Solve for y
[tex]y = \frac{1}{3}x +1 +1[/tex]
[tex]y = \frac{1}{3}x +2[/tex]

The provided arithmetic sequence adds up to 60.
What is an arithmetic sequence?The difference between every two successive terms in an arithmetic series is always the same. The number "a" is the first term, and "d" is the common difference between the sequence. The nth term of an arithmetic sequence is given by. aₙ = a + (n – 1)d
Given an arithmetic sequence 12, 14,16,18
The general formula for the Sum of arithmetic sequence:
Sn = n/2 [2a+(n−1)d]
where: n = the number of terms to be added.
a = the first term in the sequence.
d = the constant value between terms.
In our case,
a = 12
n = 4
and d = 14 - 12 = 2
thus
Sum = 4/2(2*12 + (4- 1 )2)
Sum = 2( 24 + 6)
Sum = 60
therefore, the Sum of the given Arithmetic sequence is 60.
