Answer:
The order is
Sherry >> Rachel>>Bobby
Step-by-step explanation:
Step one:
We want to find the smallest unit rate
given data
1. Bobby fills his bucket at a rate of 3/4 gallon in 2 minutes.
unit rate
=3/4/2
=3/4*1/2
=3/8
=0.375 gallons per minute
2. Rachel can fill her bucket at 1/5 gallon in 1/2 minute.
unit rate
=1/5/1/2
=1/5*2/1
=2/5
=0.4 gallons per minute
3. Sherry can fill 3/8 gallon in 3/4 minute.
unit rate
=3/8/3/4
=3/8*4/3
=12/24
=0.5 gallons per minute

Part 3: 9 Dogs
Step-by-step explanation:
It says that the ratio they want you to put it in is dogs/students, so dogs are x, and students are y, so if there are 4 students for every dog, 36 students would require 9 dogs
And if the roles were switched it would be students x, dogs y, and there would be 9 students for 36 dogs :D

Y-4=3(x - 1)
Identify slope
and what is an “anchor point”
Find the equation of the line.
Use exact numbers.
y =
x+
Can I please get an explanation :)
Answer:
the equation is in form
y=mx+b where
m=slope
and
b=y-int (the y value for the vertex)
first we look to see what the y value is for the point where x=0 and we can see that it is 5 so b=5
then we look at the slope, slope it the amont of units up then to the side are needed to reach the next point, in this case the line goes up 1 then to the right 1 so the slope is 1/1 (1) so the full equation is
y=x+5
Step-by-step explanation:
For the equation y = 2.5X, choose which ordered pairs would be on the line if it was graphed? Select ALL that apply.

Write an equation of the line that passes through (-1,4) and is perpendicular to the line shown.
Answer:
y= -3/4x - 4Step-by-step explanation:
To write an equation that is perpendicular to a given line, take the negative reciprocal of the given slope. the given slope is 4/3, so the negative reciprocal is -3/4.
Using slope-intercept form of a linear equation, y=mx+b substitute in -3/4 for "m" the slope.
y=-3/4x+b
Now you need to "b" the y-intercept using the given point (-4,-1). Substitute the values in the equation. -1=-3/4(-4)+b simplify
-1= 3 + b subtract 3 for both sides
-4=b
substitue -4 for b. Now you have y= -3/4x - 4 this is your answer.

Which unit rate is equivalent to 17 miles per gallon? (5 points)
Question 1 options:
1) 3 gallons
_________
51 miles
2) 51 miles
______
3 gallons
3) 34 miles
_____
4 gallons
4) 4 gallons
______
34 miles
Answer:
The answer would be option 2) 51 miles/3 gallons.
Step-by-step explanation:
First, every 17 miles needs 1 gallon. If you add 17 more miles, it'll be 34 miles and you'll need a 2nd gallon, so you can already eliminate options 3 and 4. If you add another 17 miles and a gallon, it'll give you 51 miles 3 gallons. Option 1 would not be the answer because if you did 3/51, you'll get a whole different answer in decimals. So the only other option to choose from is option 2.
In parallelogram STUV, find the measure of TS.
Answer:
123.8 cm
Step-by-step explanation:
well we know that STUV is a parallelogram (given)
so by properties of a parallelogram we know that opposite sides are congruent (in other words equal)
so we have that
VU=TS
and we know that VU=123.8 cm (given)
so TS=123.8

A right square pyramid is shown. The height of the pyramid is 6 units. The distance from the center of the base of the pyramid to vertex D is 2.5 units, as shown. Find the length of segment AD, in units.
Answer:
Length of side AD is 6.5 units.
Step-by-step explanation:
Let the center of the rectangular base of the given pyramid is O,
From the picture attached,
m∠AOD = 90°
By applying Pythagoras theorem in the right triangle AOD,
AD² = AO² + OD²
AD² = 6² + (2.5)²
AD = √42.25
AD = 6.5 units
Therefore, length of side AD is 6.5 units.

Step-by-step explanation:
(f ◦ g)(3) = f(g(3))
Each of the coordinate pairs for g correspond to ...
(x, g(x))
Then g(3) can be found by looking for the pair that has 3 in the first location. That ordered pair is ...
(3, 4)
so we know that g(3) = 4.
Now, we know that f(g(3)) = f(4). This tells us to look for the ordered pair in the f relation that has 4 as its first value. That ordered pair is ...
(4, 9)
so we know that f(4) = 9.
__
In summary, ...
(f ◦ g)(3) = f(g(3)) = f(4) = 9
how do I Translate the following verbal statement into an algebraic equation and then solve: Krystal bought a nightstand on sale for $170, which was one-fourth of the original price. What was the original price of the nightstand
Answer:the original price is $680
Step-by-step explanation:
1/4(x)=170
4×1/4(x)=4×170
x=$680
The original price of the nightstand is $680.
What is an equation?In mathematics, an equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Krystal bought a nightstand on sale for $170, which was one-fourth of the original price.
Let the original price of nightstand be x.
Now, 1/4x =170
x=170×4
x=$680
Therefore, the original price of the nightstand is $680.

Matthew dropped a tennis ball off the roof of 100 foot tall building. The objects height (y) is modeled by the equation below. At what time (t) does the ball hit the ground? Round your answer to the nearest tenth
Answer:
2 seconds later
Step-by-step explanation:
Since the required equation is lacking, let the equation modeled by the height be expressed as y = -16t² + 64
The ball hits the ground at y =0. Substitute y = 0 into the expression and find t;
Since y = -16t² + 64
0 = -16t² + 64
16t² = 64
t² = 64/16
t² = 4
t = ±√4
t = 2 and -2
Time cannot be negative, hence the ball hits the ground 2 seconds later.
Note that the equation used was assumed. Similar solution can be applied for any given equation.

Sean and his chartered a fishing boat for the day Sean caught a blue marlin and an amberjack. The weight of the blue marlin way 12 times as great of the amberjack. The combined weight of both fish was 273 pounds. How much did each fish weight
Answer:
The weight of the blue marlin = b = 252 pounds
The weight of the amber jack = a = 12 pounds
Step-by-step explanation:
Sean and his chartered a fishing boat for the day Sean caught a blue marlin and an amberjack.
Let
The weight of the blue marlin = b
The weight of the amber jack = a
The weight of the blue marlin weigh 12 times as that of the amberjack.
b= 12a
The combined weight of both fish was 273 pounds.
= a + b = 273 pounds
b = 12a
Hence
a + 12a = 273 pounds
13a = 273 pounds
a = 273 pounds/13
a = 21 pounds
b = 12a
b = 12 × 21 pounds
= 252 pounds
Hence:
The weight of the blue marlin = b = 252 pounds
The weight of the amber jack = a = 12 pounds

OxIXER, x>-3)
O {XIXER, x > 3)
O XIXER,X>7)
Answer:
The solution set is {x : x ∈ R, x > 3} ⇒ C
Step-by-step explanation:
The solution set of the inequality x > a is {x : x ∈ R, x > a}The solution set of the inequality x < a is {x : x ∈ R, x < a}The solution set of the inequality x ≥ a is {x : x ∈ R, x ≥ a}The solution set of the inequality x ≤ a is {x : x ∈ R, x ≤ a}Let us solve the question
∵ x - 5 > -2
→ Add 5 to both sides of the inequality
∴ x - 5 + 5 > -2 + 5
∴ x > 3
→ By using the first rule above
∴ The solution set is {x : x ∈ R, x > 3}
