Michela is training for a race. She runs 5 miles in 52 minutes. Her goal is to run 6 miles in 1 hour. By how many minutes per mile must Michela decrease the rate to meet her goal? explain your reasoning.
Answer:
.4
Step-by-step explanation:
52/ /4= 10.4
60/6=10
10.4-10=.4
Michela needs to increase her speed by 0.23 miles/hour to attain her goal.
What is the rate of change?The rate of change is the change of a quantity over 1 unit of another quantity.
Most of the time the rate of change is the change with respect to time.
For example the speed 3meter/second.
As per the given,
She runs 5 miles in 52 minutes.
5 miles in (52/60) hour
In 1 hour → 5(60/52) = 300/52 = 5.769
Her goal was 6 miles in 1 hour.
5.769 + x = 6
x = 0.23 miles/hour
Hence "Michela needs to increase her speed by 0.23 miles/hour to attain her goal".

you pick a card, roll a die, and find the sum. How many different sums are possible?
If we pick a card, roll a die, and find the sum , the different sums possible is 17.
What is Permutation and Combination ?A permutation is an act of arranging the objects or numbers in order.
Combinations are the way of selecting the objects or numbers from a group of objects or collection, in such a way that the order of the objects does not matter.
If we pick any card and roll a die
The sum possible is
The highest it can be would be 13(card) + 6(die) =19
the Lowest it can be would be 1(card) + 1 (die) = 2
So the different sums possible is 19-2 = 17.

A store is having a sale on trail mix and jelly beans. For 5 pounds of trail mix and 3 pounds of jelly beans, the total cost is $18. For 2 pounds of trail mix and 12 pounds of jelly beans, the total cost is $45. Find the cost for each pound of trail mix and each pound of jelly beans.
The cost for each pound of trail mix is $1.5 and each pound of jelly beans is $3.5 .
What is elimination method?The elimination method is the process of eliminating one of the variables in the system of linear equations using the addition or subtraction methods in conjunction with multiplication or division of coefficients of the variables.
According to the question
A store is having a sale on trail mix and jelly beans .
Let trail mix = T
and jelly beans = J
For 5 pounds of trail mix and 3 pounds of jelly beans, the total cost is $18.
i.e
5T + 3J = 18 -------------------------- (1)
For 2 pounds of trail mix and 12 pounds of jelly beans, the total cost is $45.
i.e
2T + 12J = 45 -------------------------------(2)
Now,
multiplying eq (1) from 4
20T + 12J = 72 -----------------(3)
Solving equation (3) and (2) the equation by elimination method
20T + 12J = 72 -----------------(3)
2T + 12J = 45 -------------------------(2)
subtracting equation (2) from (3)
18T = 27
T = 1.5
substituting the value of T in equation 1
5T + 3J = 18
5*1.5 + 3J = 18
7.5 + 3J = 18
3J = 18 - 7.5
3J = 10.5
J = 3.5
Hence, the cost for each pound of trail mix is $1.5 and each pound of jelly beans is $3.5 .

Step-by-step explanation:
The mnemonic SOH CAH TOA is intended to remind you of the relationships ...
Cos = Adjacent/Hypotenuse
Tan = Opposite/Adjacent
__
Translated to the figure at hand, these are ...
cos(35°) = 10/y ⇒ y = 10/cos(35°) ≈ 12.21
tan(35°) = x/10 ⇒ x = 10·tan(35°) ≈ 7.00

An airplane takes off 200 yards in front of a 60 foot building. At what angle of elevation must the plane
take off in order to avoid crashing into the building?
Answer:
16.69°
Step-by-step explanation:
Given that,
Height of the building, h = 60 foot
Distance from the base of the building, b = 60 foot
We need to find the angle of elevation must the plane takes off in order to avoid crashing into the building. So,
[tex]\tan\theta=\dfrac{60}{200}\\\\\theta=\tan^{-1}\dfrac{60}{200}\\\\=16.69^{\circ}[/tex]
So, the required angle is 16.69°.

What is the equation of the line in slope-intercept form?
Answer:
y=-5x+6
Step-by-step explanation:
To find your slope (or m value), you must identify 2 points that your line crosses through (I used (1,1) and (0,6). You can either count up and over to the point (0,6) from (1,1), or you can use the formula y2-y1/x2-x1 (it would look like 6-1/0-1). This will give you -5 for your slope.
Your x-intercept (or b value) is 6 because you can see from the graph that that is where your line intercepts y.
