Answer:
0 = 0 miles
1 = 1.5 miles
2 = 3 miles
3 = 4.5 miles
4 = 6 miles
5 = 7.5 miles
Step-by-step explanation:
multiply each hour by 1.5
If a garden snail travels 1.5 miles per hour, then when 0 hours pass, it would have travelled 0 miles (no time has passed).
After 1 hour, it would have travelled 1.5 miles.
After 2 hours, it would have travelled 3 miles (1.5 miles × 2 hours).
After 3 hours, it would have travelled 4.5 miles (1.5 miles × 3 hours).
After 4 hours, it would have travelled 6 miles (1.5 miles × 4 hours).
After 5 hours, it would have travelled 7.5 miles (1.5 miles × 5 hours).
I hope this helps!

Here are two similar rectangles find the area of the largest one
Answer:
40.32 cm²
Step-by-step explanation:
The area of the small rectangle = 7 × 4 = 28 cm²
Given the ratio of the sides of similar rectangles = a : b , then
the ratio of the areas = a² : b²
Here ratio of sides = 4 : 4.8 = 1 : 1.2
ratio of areas = 1² : 1.2² = 1 : 1.44
Let x be the area of the larger rectangle then by proportion
[tex]\frac{1}{28}[/tex] = [tex]\frac{1.44}{x}[/tex] ( cross- multiply )
x = 40.32
Area of larger rectangle is 40.32 cm²

1 Four sets of ordered pairs are shown below.
a. {(2, -4), (-3, -5), (-3, 3), (-2, 6)}
b. {(5,2), (3, 2), (-1, 2), (3,4)}
C. {(-6, -4), (3, -4), (-2,-4), (5, -4)}
d. {(3, 2), (-3, -2), (3, 6), (8, 2)}
Which set(s) of ordered pairs do NOT represent a function?
A a only
B a and c only
C a, b, and d only
D All of the above
Answer:
c
Step-by-step explanation:
its a, b, and d because these have inputs with different outputs
ex. (-3,-5) and (-3,3)
Answer:
The answer is C. a, b, and d only.
Step-by-step explanation:
A is not a function because -3 has two y like, (-3,-5) and (-3,-3).
B is not a function because like A, it has an x that has more than one y value, like (3,2) and (3,4)
C is a function because all the x values only have one y value, even though there are many x values that contain the same y value but to be a function the x value must not repeat (only if the y value is the same) or have multiple y values for the same x value.
D is not the function because the x value 3 has two different y values, (3,2) and (3,6)

A traveler is walking on a moving walkway in an airport. The traveler must walk back on the walkway to get a bag he forgot. The traveler's ground speed is 1 fts against the walkway and 5 ft/s with the walkway. What is the traveler's speed off the walkway? What is the speed of the moving walkway? The traveler's speed off the walkway is ft/s.
Answer: here is your answer
Step-by-step explanation:
You can put this solution on YOUR website!
+t+ = traveler's speed in ft/sec
+w+ = walkway's speed in ft/sec
given:
+t+-+w+=+2+
+t+%2B+w+=+6+
-------------
Add the equations
+2t+=+8+
+t+=+4+
and
+t+%2B+w+=+6+
+4+%2B+w+=+6+
+w+=+2+
The traveler's speed off the walkway is 4 ft/sec
The speed of the moving walkway is 2 ft/sec

Naomi's square bedroom has an area of 90 square feet. What is the length of one of the walls? Round to the nearest tenth if necessary.
Answer:
9.48 ft
Step-by-step explanation:
Step one:
given data
Naomi's square bedroom has an area of 90 square feet
Area of the room = 90 ft^2
Required
the length of the side of the room
Step two:
we know that area is
A= L^2
substitute
90= L^2
L= √90
L=9.48 ft
Keisha is reading a 310 page book at a rate of 23 pages per day.Use a point-slope equation to determine how many pages she will have left to read after reading the book for 10 days. She will still have [ ] pages left to read after 10 days.
Answer:
80 pages
Step-by-step explanation:
Point slope Equation is :
y = mx + c
In the above question
y = 310 pages
x = number of days = 10 days
m= 23 pages per day
c = ?? Unknown
c = y - mx
c = 310 - 23 × 10
c = 310 - 230
c = 80 pages
She will still have 80 pages left to read after 10 days

Write the equation of the line, in point-slope form. Identify (x1, y1) as the point (-2, 2). Use the box provided to submit all of your calculations and final answers.
Answer:
Slope: -1
Point-Slope Form: y - 2 = -1 (x - (-2))
Step-by-step explanation:
Answer: y-2=-1(x+2)
Step-by-step explanation: use whichever points you want I’m using (-2,2)
Find slope: y2-y1/x2-x1 so 2+2/-2-2 = 4/-4 = -1
Plug in these into y-y1= m(x-x1)
y-2= -1(x+2)

A car manufacturer produced 5,000 cars for a limited edition model. Dealers sold all of these cars at mean price
of $36,000 with a standard deviation of $3,000. Suppose we were to take random samples of 9 of these cars
and calculate the sample mean price x for each sample.
Answer:
μₓ = 36,000 dollarsσ ₓ= 1,000 dollarsShow work:to find μₓ = 36,000 dollars:
Look in the question, it states that the mean is $36,000.
to find σ ₓ= 1,000 dollars:
[tex]\frac{3000}{\sqrt{9} } = 1000[/tex]In order to solve the equation 9x = -3 (2+ 3y) for y a student simplifies the equation as shown
Step 1: 9x = –3x + -3 (Gy)
Step 2: 9x = -3x + - y
Step 3: 92
Step 4: 6x = -Y
Step 5: Y = -6
3x = -Y

A chef is going to use a mixture of two brands of Italian dressing the first brand contains contains 7% vinegar and the second brain contains 12% vinegar the chef wants to make 220 mL of dressing that is 11% vinegar how much of each branch should he said he use
Answer:
176 of 12% vinegar
44 of 7% vinegar
Step-by-step explanation:
Percentage vinegar required = 11%
Volume = 220 mL
First brand % = 7%
Second brand % = 12%
Let p = volume of 12% vinegar material
Mixture :
0.12p + 0.07(220 - p) = 220 * 0.11
0.12p + 15.4 - 0.07p = 24.2
0.05p = 8.8
p = 8.8 / 0.05
p = 176
176 of 12% vinegar and
220 - 176 = 44
44 of 7% vinegar
An astronaut drops a rock off the edge of a cliff on the moon. The distance d(t), in meters, the rock travels after t seconds can modeled by the function d(t)= .5x^2. What is the average speed, in meters per second, of the rock between 5 and 10 seconds after it was dropped
Answer:
The average speed is 7.5 [tex]\frac{ m}{ s}[/tex]
Step-by-step explanation:
Speed is a physical quantity that expresses the relationship between the space traveled by an object and the time used for it.
Then, the average speed relates the change in position to the time taken to effect that change:
[tex]speed=\frac{change in position}{change in time}[/tex]
The change in position is the difference between the final position and the initial position, while the change in time is the difference between the final and initial time.
In this case, the starting and ending positions are calculated by replacing the times in the function of the distance d (t):
d(5)= 0.5*5²= 12.5 m
d(10)= 0.5*10²= 50 m
So:
change in position= final position - initial position= 50 m - 12.5 m= 37.5 mchange in time= 10 s - 5 s= 5 sReplacing in the definition of speed:
[tex]speed=\frac{37.5 m}{5 s}[/tex]
and solving you get:
speed= 7.5 [tex]\frac{ m}{ s}[/tex]
The average speed is 7.5 [tex]\frac{ m}{ s}[/tex]
