Answer:
A, B & C are inversely proportional.
Step-by-step explanation:
For two quantities like x and y to be inversely proportional, they are to be written as;
y ∝ 1/x
This means that if x increases, then y decreases and if x decreases, then y increases.
A) The time it takes to drive 100 miles and the average driving speed.
Now, formula for time in motion is;
Time = Distance/speed
Let's denote time as t and speed as v.
Thus;
t = 100/v
From this relationship, it's clear that when v increases, then t decreases and vice versa. Thus it is inversely proportional.
B) The lengths of sides of a rectangle if the perimeter is fixed.
Perimeter of a rectangle is given as;
P = 2(L + W)
Where L is length and W is width.
Now, if the perimeter is fixed, it means an increase in the length will lead to a decrease in the width and vice versa. Thus, it is inversely proportional
C) The lengths of sides of a rectangle if the area is fixed.
If the sides are x & y.
Then;
A = xy
A/x = y
This means that;
1/x ∝ y.
Thus, the sides will be inversely proportional.

When solving the equation 3y+11=35 , which operation do you "undo" first?
Answer:
the addition
Step-by-step explanation:
3y + 11 = 35
-11 -11
-----------------
3y = 24
-----------
3 3
----------
y = 8
Answer:
you can really do whatever as long as you keep the equation balanced but if your teacher is expecting something specific from you then you would undo 11 (take away 11 from both sides)
Step-by-step explanation:
3y + 11 = 35 original equation
3y = 24 subtract 11 from both sides
y = 8 divide both sides by 3 to get y alone

The cost, c, to rent a kayak for h hours is shown in the table below.
I fr forgot how to do rate of change please help me lol
Answer:
Rate of change in the rent of yak = $5 per hour
Step-by-step explanation:
Rate of change in the cost from the table is given by the formula,
Rate of change = [tex]\frac{\triangle C}{\triangle h}[/tex]
Where ΔC = Change in the rate of the yak
Δh = Change in time
Change in the rent of yak = ΔC = 30 - 25
= $5
Change in time = Δh = 3 - 2
= 1 hours
Rate of change = [tex]\frac{5}{1}[/tex]
= $5 per hour

example :-
Answer:
A car travel 90km in 2.5 hours, How much time is required to cover 60km with the same speed?
find the distance covered in 4 hours?
90km →2.5hrs.
Speed= 2.5/90=36 km/hr
i) Time required = 36/60 = 3/5 hrs
Distance covered=36×4=144km.

Write an equation in slope-intercept form for the line that passes through (5, 3) and is parallel to x + 3y = 6.
Answer:
Step-by-step explanation:
the line given is
[tex]x + 3y = 6\\3y = -x + 6\\y = \frac{-1}{3} (x) + 2\\[/tex]
parallel lines have the same slope
[tex]y = \frac{-1}{3} (x) + b\\3 = \frac{-1}{3}(5) + b\\\frac{9}{3} = \frac{-5}{3} + b\\ b = \frac{14}{3}\\[/tex]
[tex]y = \frac{-1}{3} (x) + \frac{14}{3}[/tex]
The equation of line passes through the point (5, 3) will be;
⇒ y = - x/3 + 14/3
What is Equation of line?The equation of line in point-slope form passing through the points
(x₁ , y₁) and (x₂, y₂) with slope m is defined as;
⇒ y - y₁ = m (x - x₁)
Where, m = (y₂ - y₁) / (x₂ - x₁)
Given that;
The point on the line are (5, 3).
And, The parallel line is,
⇒ x + 3y = 6
⇒ y = - x/3 + 2
Now,
Since, The equation of line passes through the point (5, 3).
So, We need to find the slope of the line.
Since, The slope of the parallel line is same.
Hence, Slope of the line is,
⇒ y = - x/3 + 2
⇒ m = dy/dx = - 1/3
⇒ m = - 1/3
Thus, The equation of line with slope - 1/3 is,
⇒ y - 3 = - 1/3 (x - 5)
⇒ y - 3 = - 1/3 (x - 5)
⇒ y - 3 = - x/3 + 5/3
⇒ y = - x/3 + 5/3 + 3
⇒ y = - x/3 + 14/3
Therefore, The equation of line passes through the point (5, 3) will be;
⇒ y = - x/3 + 14/3

The path of a projectile
launched from a 16-ft-tall tower
is modeled by the equation
y = −16x2 + 64x + 16. Graph the
equation. What is the maximum
height, in feet, reached by the
projectile?
(On a graph)
Answer:
The maximum height reached by the projectile is 80 feet
Step-by-step explanation:
The given equation of the path of the projectile is y = -16·x² + 64·x + 16
Where;
y = The height in feet, reached by the projectile (Assumption)
x = The time it takes the projectile to reach the height, y (Assumption)
The shape of the given equation of the path of the parabola is that of a parabola turned upside down.
We have that the maximum height is given by the top of the curve where the curve changes direction, and the slope = 0
Therefore, we have;
[tex]Slope = \dfrac{\mathrm{d} y}{\mathrm{d} x} = \dfrac{\mathrm{d} \left (-16\cdot x^2 + 64\cdot x + 16 \right )}{\mathrm{d} x} = -32 \cdot x + 64 = 0[/tex]
Therefore, at the maximum point, the slope is -32·x + 64 = 0
∴ x = -64/(-32) = 2 at the maximum point
The height at the maximum point = The maximum height, [tex]y_{max}[/tex], is found by finding the value of y (the height) at x = 2 (the value of x at the maximum point)
Therefore, we have;
[tex]y_{max}[/tex] = -16 × 2² + 64 × 2 + 16 = 80 feet
The maximum height reached by the projectile, [tex]y_{max}[/tex] = 80 feet.
Answer:
The maximum height reached by the projectile is 80 feet

I don’t know how to measure the angles
Answer:
the measure of the angle is 130°
Step-by-step explanation:
50 and ? are supplementary angles
supplementary angles add up to 180
50 + ? = 180
subtract 50 from both sides of the equation
50 + ? - 50 = 180 - 50
? = 180 - 50
? = 130

A shopper needs 48 hot dogs. The store sells identical hot dogs in 2 differently sized packages. They sell a six-pack of hot dogs for $2.10, and an eight-pack of hot dogs for $3.12. Should the shopper buy 8 six-packs, or 6 eight-packs?
Group of answer choices
A. He should buy 6 eight-packs because the unit rate is 39 cents per bun.
B. He should buy 6 eight-packs because the unit rate is 37 cents per bun.
C. He should buy 8 six-packs because the unit rate is 35 cents per bun.
D. He should buy 8 six-packs because the unit rate is 33 cents per bun.
Answer:
C
Step-by-step explanation:
A six back has a value of 35 cents per bun,
you may find this by dividing 2.10 by 6 and getting .35 per
while a 8 pack 3.12 divided by 8 is .39
so it is more economical or correct to get C. 8 six packs for 35 cents a bun
Here are three different recipes for Orangey-Pineapple Juice. Two of these mixtures taste the same and one tastes different. Which two recipes will taste the same, and which one will taste different? Recipe 1: Mix 4 cups of orange juice with 6 cups of pineapple juice.
Answer:
recipe 1 and recipe 2 will taste the same because they have the same ratio while recipe 3 will taste differently because it has a different ratio.
Step-by-step explanation:
Here are three different recipes for Orangy-Pineapple juice. Two of these mixtures taste the same and one tastes different.
Recipe 1: Mix 4 cups of orange juice with 6 cups of pineapple juice.
Recipe 2: Mix 6 cups of orange juice with 9 cups of pineapple juice
Recipe 3: Mix 9 cups of orange juice with 12 cups of pineapple juice
Which two recipes will taste the same, and which one will taste different? explain or show your reasoning.
Recipe 1: Mix 4 cups of orange juice with 6 cups of pineapple juice.
Ratio of orange juice to pineapple juice = 4 : 6
= 4 / 6
= 2/3
= 2 : 3
Recipe 2: Mix 6 cups of orange juice with 9 cups of pineapple juice.
Ratio of orange juice to pineapple juice = 6 : 9
= 6 / 9
= 2 / 3
= 2 : 3
Recipe 3: Mix 9 cups of orange juice with 12 cups of pineapple juice
Ratio of orange juice to pineapple juice = 9 : 12
= 9 / 12
= 3 / 4
= 3 ; 4
Therefore, recipe 1 and recipe 2 will taste the same because they have the same ratio while recipe 3 will taste differently because it has a different ratio.
