Answer:
A) 49.4
B) 40
C) 0.00539
D)583.33
Step-by-step explanation:
A)
1 meter/3.25 feet = 15.2 meters/x feet
x feet * 1 meter = 15.2 meters* 3.25 feet
x = 15.2 meters* 3.25 feet/1 feet* meter
x = 49.4
B) 1.6 kilometers/1 mile = x kilometers/25 miles
multiplying both sides by 25 miles
(1.6 kilometers/1 mile )* 25 miles =( x kilometers/25 miles) * 25 miles
=> 40 kilometers = x kilometers
x = 40
C) 0.926 meter/1 yard = 200 meters/x yards
dividing both sides 200 meters
0.926 meter/(1 yard*200 meters) = 200 meters/(x yards *200 meters)
185.2 /1 yard = 1/ x yards
x yards = 1 yards/185.2
=> x = 0.00539
D) 1 kilometers/0.6 mile = x kilometers/350 miles
multiplying both sides by 350 miles
(1 kilometers/0.6 mile ) 350 miles= (x kilometers/350 miles) 350 miles
=> 583.33 kilometers = x kilometers
x = 583.33

Step-by-step explanation:
A biker travels the 120 mi from New York , NY to Wilmington, DE in 8 hours. A bus, a truck, and a rider on a horse take the same route as the biker. At what speed does each of them travel if it takes them 2 hours, 2.5 hours, and 18.75 hours respectively to reach Wilmington? Do the speed and the time vary directly or inversely proportional when the same distance is traveled? Explain why.
Answer:
The speed is inversely proportional to the time when the same distance is traveled.
Step-by-step explanation:
Given that:
The distance traveled by the biker in 8 hours is 120 mi.
The speed of the biker=120/8=15 mi/hr.
[as speed=Distance travelled/Time taken]
As all take the same route, so the distance traveled by all is the same which is 120 mi
The time taken by the bus to cover this distance is 2 hours.
So, the speed of the bus = 120/2=60 mi/hr.
The time taken by the truck is 2.5 hours.
So, the speed of the truck = 120/2.5=48 mi/hr.
And the time taken by the rider is 18.75 hours.
So, the speed of the rider = 120/18.75=6.40 mi/hr.
Now, observe that to cover the same distance, the bus takes the least time, so, the bus is traveling at the fastest speed among all, while the rider has the slowest speed as the distance is the same for all. The truck and the biker have speed in between the speed of the bus and the rider.
It can be concluded that when the time of the journey for the same distance is less than speed is more.
So, the speed is inversely proportional to the time when the same distance is traveled.
Or, [tex]\text{Speed}\propto\frac{1}{Time}[/tex]

What is the value of g?
−5+7g=3g+9
g=−1
g = 1
g=125
g=312
Answer:
D
Step-by-step explanation:
We have the equation:
[tex]-5+7g=3g+9[/tex]
Add 5 to both sides:
[tex]7g=3g+14[/tex]
Subtract 3g from both sides:
[tex]4g=14[/tex]
Divide both sides by 4:
[tex]g=14/4[/tex]
We can spilt this into:
[tex]g=12/4+2/4[/tex]
Simplify:
[tex]g=3\frac{1}{2}[/tex]
So, our answer is D.
And we're done!
Answer:
g = 3 1/2
Step-by-step explanation:
−5 + 7g = 3g + 9
Subtract 3g from both sides.
−5 + 4g = 9
Add 5 to both sides.
4g = 14
Divide both sides by 4.
g = 14/4
Reduce the fraction.
g = 7/2
Change the fraction into a mixed numeral.
g = 3 1/2

A data set lists weights (lb) of plastic discarded by households. The highest weight is 5.29 lb, the mean of all of the weights is x=1.995 lb, and the standard deviation of the weights is s=1.305 lb. a. What is the difference between the weight of 5.29 lb and the mean of the weights? b. How many standard deviations is that [the difference found in part (a)]? c. Convert the weight of 5.29 lb to a z score. d. If we consider weights that convert to z scores between −2 and 2 to be neither significantly low nor significantly high, is the weight of 5.29 lb significant?
Answer:
Follows are the solution to this question:
Step-by-step explanation:
In point a:
The weight difference between 5.29 lb and the weighted mean:
[tex]=5.29-1.995 \\\\=3.295[/tex]
In point b:
The number of standard deviation:
[tex]=\frac{3.295}{1.305} \\\\ =2.52[/tex]
In point c:
[tex]z score= \frac{x- \mu}{\sigma}\\\\[/tex]
[tex]=\frac{ 1.995- 5.29}{1.305}\\\\=\frac{-3.295}{1.305}\\\\= - 2.52[/tex]
In point d:
No, since (-2, 2) included with the Zero is the z score and for weight is 5.29.

She missed her goal, because she made more than $75 on coffee today.
Answer:
She missed her goal, because she made less than $75 on coffee today.
Step-by-step explanation:
Gabriela, did not meet her goal because she only mad 72$ today
if you do
80 cents times 90 cups you only get 72$
meaning that she was 3$ short from meeting her goal.

Two angles are supplementary. The measure of the smaller angle is four more than one third the measure of the larger angle. The measure of the larger angle is
Answer:
132
Step-by-step explanation:
2 Angles are supplementary:
x + y = 180
The smaller angle is four more than one third of other:
y = 1/3x + 4
Plug in y into the original equation:
x + 1/3x + 4 = 180
Solve the equation:
4/3x = 176
x = 176 * 3/4
x = 132
y = 48
x is the larger angle so 132 is the answer
The measure of smaller and larger angles will be 48 degrees and 132 degrees, respectively.
Given information:
The two angles are supplementary. Let them be x (larger) and y (smaller).
The measure of the smaller angle is four more than one-third the measure of the larger angle.
The above condition can be written as,
[tex]y=4+\dfrac{ x}{3}[/tex]
Supplementary angles are the angles whose sum of measure is equal to 180 degrees.
So, [tex]x+y=180[/tex]
Solve the above two equations as,
[tex]x+y=180\\x+(4+\dfrac{ x}{3})=180\\\dfrac{4x}{3}=176\\x=176\times \dfrac{3}{4}\\x=132\\y=48[/tex]
Therefore, the measure of smaller and larger angles will be 48 degrees and 132 degrees, respectively.

A class of 24 students went on a picnic. They had a choice between having a turkey sandwich or a vegetarian sandwich. Eighteen students selected turkey, and the rest selected vegetarian. Write a ratio to compare the number of turkey sandwiches to the number of vegetarian sandwiches.
4 : 3
4 : 1
1 : 3
3 : 1
I believe it is the ratio 3 : 1.
18 students chose the turkey sandwich.
Since the class has a total of 24 students, we can deduce that 6 students chose the vegetarian sandwich.
This gives us a ratio of 18 : 6.
When simplified, we get a ratio of 3 : 1.

A map on a coordinate plane places two cities on coordinates. Upland is located at (25, 5) and Highland is located at (50, 10). If each unit on the map represents one mile, approximately how many miles apart are the two cities?

Location of both the cities are [tex] (25,\: 5)=(x_1, \:y_1) \:\&\: (50,\: 10)=(x_2 , \:y_2) [/tex]
The distance between two cities can be obtained by using distance formula:
