Answer:
The answer will be B ($71.36)
Step-by-step explanation:
17 ft. = 17/3 yd.
2 inch. = 2/(12 x 3) yd.
The cost will be: 40 x (17/3) x (17/3) x (2)(12/3) = 5780/81 = $71.358024...

Answer:
a) 7:24 pm
b) later than 7:24 pm
Step-by-step explanation:
The relationship between time, speed, and distance can be written as ...
time = distance/speed
So, Faris's travel time to London is predicted to be ...
time = (195 mi)/(50 mi/h) = 3.9 h = 3:54 hours
__
a) Faris's expected arrival time at a speed of 50 mph is ...
3:30 pm +3:54 = 6:84 pm = 7:24 pm
__
b) Time is inversely proportional to speed, so a lower speed will result in a longer time.
Faris's arrival time will be later than 7:24 pm.
You bought a magazine for $5 and four erasers. You spent a total of $25. How much did each eraser cost? Include a let statement in your answer.
Answer:
5$??.
Step-by-step explanation:
If a magazine was 5$, 25-5= 20. So then, 20÷4= 5. There fore an eraser costs 5$.
Answer:
5 dollars
Step-by-step explanation:
Let x be the price of each eraser
We bought a magazine and 4 erasers with 25 dollars
so : 5+4x = 25⇒ 4x= 20⇒x= 20/4⇒ x=5
The eraser costs 5 dollars

[tex] x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a} [/tex]
Step-by-step explanation:
One line has
[tex] x + \dfrac{b}{2a} = \pm \dfrac{\sqrt{b^2 - 4ac}}{2a} [/tex]
The next line's reason is that b/2a was subtracted from both sides.
The missing line is:
[tex] x = -\dfrac{b}{2a} \pm \dfrac{\sqrt{b^2 - 4ac}}{2a} [/tex]
Then it simplifies to
[tex]x = \dfrac{-b \pm \sqrt{b^2 - 4ac}}{2a}[/tex]
Carol is cross-country skiing. The table shows the distance she traveled after various numbers of minutes. What is the rate of change? Distance Carol Traveled while Cross-Country Skiing Minutes Distance Traveled (miles) 2 StartFraction 1 Over 6 Endfraction 3 StartFraction 17 Over 48 EndFraction 4 StartFraction 13 Over 24 EndFraction 5 StartFraction 35 Over 48 EndFraction 6 StartFraction 11 Over 12 EndFraction StartFraction 1 Over 12 EndFraction StartFraction 1 Over 6 Endfraction StartFraction 3 Over 32 EndFraction StartFraction 3 Over 16 EndFraction
Answer:
3/16 miles/minute
Step-by-step explanation:
A rate of change describes how an output quantity changes relative to the change in the input quantity.
Points given:
Input Output
2 1/6
3 17/48
4 13/24
5 35/48
6 11/12
Here input values describe the time in minutes from 2 to 6 and output values describe the distance in miles from 1/6 to 11/12
Calculating the rate of change using the first two pairs of input-output values
Relative change = change in distance/change in time
(17/48 - 1/6)/(3-2) = (17/48 - 8/48) /1 = 9/48 = 3/16 miles/minute
We will get the same result if we take any other ordered pair of input and output values.
So D is your answer! Hope this helped!
Rate of change is the change in a particular variable, over another variable.
The rate of change is: 3/16 miles per minutes
To calculate the rate of change, we select any two points on the table (see attachment)
[tex](x_1,y_1) = (2,\frac 16)[/tex]
[tex](x_2,y_2) = (3,\frac{17}{48})[/tex]
The rate of change (m) is calculated as follows:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
So, we have:
[tex]m = \frac{\frac{17}{48} - \frac{1}{6}}{3-2}[/tex]
[tex]m = \frac{\frac{17}{48} - \frac{1}{6}}{1}[/tex]
[tex]m = \frac{17}{48} - \frac{1}{6}[/tex]
Take LCM
[tex]m = \frac{17- 8}{48}[/tex]
[tex]m = \frac{9}{48}[/tex]
Reduce fraction
[tex]m = \frac{3}{16}[/tex]
Hence, the rate of change is: 3/16 miles per minutes

Trying to find the missing segment to the triangle in the attached image. Any help would be appreciated. Thanks.
Answer:
24 unit
Step-by-step explanation:
This question can be solved using concept of basic proportionality theorem,
according to this theorem, if a line is drawn parallel to one side of the triangle and intersect the other two sides then the two sides are divided in the same ratio.
Example:
let there be a triangle ABC
if DE is drawn parallel to BC such that D is a point on line AB and E is other point on AC, then
AD/DB = AE/EC (basic proportionality theorem)
_____________________________________
Similarly in this problem
15/5 = ?/8
3= ?/8
? = 8*3 = 24
Thus. missing segment value is 24 unit.

A garden hose supplies 36 gallons of water in 3 minutes.Use a table of equivalent ratios to show the garden hose's water flow in gallon per minute and minutes
Answer:
Garden hose water flow in gallons per minute(x:y) = 12:1
Minutes per gallon water flow(y:x) = 1:12
Step-by-step explanation:
Complete question below
A garden hose supplies 36 gallons of water in 3 minutes. Use a table of equivalent ratios to show the garden hose's water flow in gallons per minute and minutes per gallon.
Let
the garden hose water flow=x
Time of glow=y
x:y=36 gallons : 3 minutes
x/y=36/3
x/y=12/1
x:y=12:1
Therefore, garden hose water flow in gallons per minute is given by
x:y = 12:1
Minutes per gallon water flow
y:x=3:36
y/x=3/36
y/x = 1/12
y:x = 1:12
Therefore, minutes per gallon water flow is given by
y:x = 1:12

Given that m angle BAC=48^ and m angle BCA=19^ , find m angle ABD
Answer:
B. 67°
Step-by-step explanation:
Step 1: Find m∠B
180 - (48 + 19) = 113°
Step 2: Use Supplementary Angles rules
180 - 113 = 67°
Answer:
m<ABD is 113 degrees
Step-by-step explanation:
The interior angles of a triangle must add up to 180 degrees.
Representing angle ABD by x, we have:
x + 48 degrees + 19 degrees => x + 67 degrees = 180 degrees.
Subtracting 67 degrees from boths sides, we get x = 113 degrees.
m<ABD is 113 degrees.

say we have the points: (2,5) (4,8) (1,7) (8,10) (13,2)
the domain would be a list of all of the x values of all of the coordinate points. therefore the domain would be:
domain:
{1,2,4,8,13}

since you have not attached the function or a graph, you will have to find the domain on your own (unless you attach one now). hope this helps!
for each graph state whether it’s a function
Answer:
Graph 1, 4, 6 are functions.
Graph 2, 3, 5 are not functions.
Step-by-step explanation:
If graph of a relation pass the vertical line test, then we can say the relation is a function.
In vertical line test, we draw a vertical line parallel to axis, if graph of relation intersect the line almost once, then we say in is a function.
To check, whether the given relation is function or not, draw verticals lines on each graph as shown below.
In graph 1, open circle means the value x=-1 is not include it that.
From the below figure it is clear that:
Graph 1, 4, 6 pass the vertical line test, so they represent functions.
Graph 2, 3, 5 does not pass the vertical line test, so they are not functions.

week she worked x hours as a tutor and her friend paid her $25 to bake a cake.
Write an expression to represent the total amount Annie earned last week.
Type your answer below:
The total amount Annie earned last week 18x+25.
What is work in math ?In conclusion, when a force acts on an object to induce a displacement, labor is done.To determine the amount of work, three quantities must be known. The force, the displacement, and the angle between the force and the displacement are the three variables.Annie earns $18 per hour. and she worked x hours .
So, total work = 18 * x = 18x
but she earned some extra cash = 25$
now Annie's total amount with extra cash = 18x + 25
Therefore, The total amount Annie earned last week 18x+25.

Answer:
2.5
Step-by-step explanation:
plato
The required value of the scale factor is 2.50 in the given dilation.
What is a scale image?Scale image is defined as a ratio that represents the relationship between the shape and size of a figure and the corresponding dimensions of the actual figure or object.
We have been given that a Polygon ABCD is dilated by a certain scale factor with the origin as the center of the dilation to form the image A'B'CD.
The length of AB = 5.6 units, and
The length of A' B' = 2.24 units.
We have to determine the value of the scale factor.
As we know scale factor is the ratio of sides in the original image and the image after dilation.
The scale factor = length of AB/length of A' B'
The scale factor = 5.6/2.24
The scale factor = 2.50
Therefore, the required value of the scale factor is 2.50.
