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.
Answers
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".

for f(x) = 2x² + 3x-10 and g(x) = 3(x-2)
find fog (3)
Answers
(f o g) = 2(9x^2 - 36x + 36) + 9x - 18 - 10
(f o g) = 18x^2 - 72x + 72 + 9x - 28
(f o g) = 18x^2 - 63x + 44
(f o g)(3) = 18(3)^2 - 63(3) + 44

Find the value of X and Y in the triangle
Answers
9514 1404 393
Answer:
x ≈ 7.00
y ≈ 12.21
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

Answers
3x - 4y = 24
-4y = 24 - 3x
y = -6 + (3/4)x
The slope is 3/4, which will be the slope for the parallel line. Now use point-slope form to find the equation for the line:
y-y1 = m(x-x1) —> y - 2 = (3/4)(x + 4)
you pick a card, roll a die, and find the sum. How many different sums are possible?
Answers
step by step: there’s six sides to a dice
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.

Answers
9514 1404 393
Answer:
1414 cm³
Step-by-step explanation:
The formula for the volume of a cylinder is ...
V = πr²h
For a radius of 5 cm and a height of 8 cm, the volume is ...
V = π(5 cm)²(18 cm) = 450π cm³ ≈ 1414 cm³
The volume of Nadia's sugar container is about 1414 cm³.

The value will be 1413 cm³ if you use 3.14 for π.
Given the equation Square root of 2x plus 1 = 3, solve for x and identify if it is an extraneous solution
Answers
(sqrt (2x + 1))² = 3²
This will simplify into,
2x + 1 = 9
Solving for the value of x gives an answer of x = 4. This value is not an extraneous root as it satisfy the original equation even if it is inside the radical sign. (I hope this is right)
What is the equation of the line in slope-intercept form?
Answers
But im only like 90% sure so dont take my word for it but i hope that right?
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.

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]
