Answer:
95.5°F
Step-by-step explanation:
Given the regression equation :
y = 1.8x - 76.9 ; the relationship between temperature (°F) and number of ice cream sold
y = number of ice cream sold
x = temperature (°F)
The temperature when 95 iccream cones are sold will be ;
Here, y = 95
Using the model :
95 = 1.8x - 76.9
95 + 76.9 = 1.8x
171.9 = 1.8x
Divide both sides by 1.8
171.9 / 1.8 = x
95.5°F = x
Hence, temperature when 95 cones of ice-cream are sold is 95.5°F
The distance between two stations is 240km. A train takes 4hrs to cover the distance. Calculate the speed of the train
Answer:
The train was travelling at 60 km/h
Step-by-step explanation:
We're already given time and distance, and speed is just distance/time, so:
240km / 4h
= (240/4) km/h
= 60km/h

Step-by-step explanation:
It appears the expected order may be ...
__
Write the formula for the arc length of a circle with central angle, θ, in degrees.
[tex]\textit{Arc Length}=\dfrac{\theta}{360^{\circ}}\cdot 2\pi r[/tex]
Replace 360° with 2π radians.
[tex]\dfrac{\theta}{360^{\circ}}=\dfrac{\theta}{2\pi}[/tex]
Replace the angle ratio in degrees with the angle ratio in radians.
[tex]\textit{Arc Length}=\dfrac{\theta}{2\pi}\cdot 2\pi r[/tex]
Simplify by cancelling
[tex]\textit{Arc Length}=\theta r[/tex]

Answer:
Store A
Step-by-step explanation:
Store A: 5% of 50 is 2.5. If we subtract the discount from the original price, we get $47.50 as the discounted price
Store B: 20% of 60 is 12. If we subtract the discount from the original price, we get $48 as the discounted price
47.50 < 48
(hope this helps)
Answer:
Store A
Step-by-step explanation:
5% of $50 is $2.50, which means that store A is $2.50 off.
20% of 60 is %12, which means store B is $12.00 off.
However, store A has an original price that is $10 less than store A, and if you do $50 - $2.50 = $47.50 and Store B's price equals out to $60 - $12 - $48.00
this means that the full price with discount is lower for store A than it is for store B

To test whether an integer, $n$, is prime, it is enough to be sure that none of the primes less than or equal to the square root of $n$ divide $n$. If you want to check that a number between 900 and 950 is prime with this rule, what is the largest prime divisor you need to test
Answer:
the largest divisor is less than the square root of that number
Step-by-step explanation:
Pick any number between 900 and 950 . For example I choose 937 . Now taking the square root of 937 would give 30.61
So divide 937 with all the primes less than 30.61
937/2, 937/3, 937/5,...................937/29
29 would be the largest divisor which is less than the square root of 937 .
29< 30.61
But if you check 937 does not divide wholly with any of the primes hence it is a prime number itself.
If any number such 925 is chosen and it gets divided wholly by another prime like 5
925 /5= 185 so it is not a prime number
Andre ran 2 kilometers in 15 minutes, and Jada ran 3 kilometers in 20 minutes. Both ran at a constant speed. Did they run at the same speed?
Answer:
They did not run at the same speed. Calculation of their speed shows that Jada was running at a higher speed.
Step-by-step explanation:
Let's first calculate the speed of each person using the units provided so that we do not complicate the question.
speed = distance covered/time taken
Andre's speed = 2 km/15 min = 0.133 km/min
Jada's speed = 3km/20 min = 0.15 km/min
Clearly we can see that Jada was running at a higher speed than Andre. The question says they were running at constant speed not equal speed. That just means each person maintained their speed, they did not get faster or slower.
Best answer gets brainiest. Mackenzie went to the mall with her mom. First, they spent 15 minutes in the shoe store. Then they spent 1 hour shopping for a dress for Mackenzie. Finally, they spent 30 minutes eating dinner at the food court. It was 6:30 P.M. when Mackenzie and her mom left the mall. What time did they start shopping?
Include A.M. or P.M. in your answer.
Answer:
They started at 4:45 pm
Step-by-step explanation:
Time spend at the mall:
15 minutes in the shoe store
1 hour shopping for a dress
30 minutes eating
Total 1 hour 45 minutes
x + 1 hour 45 minutes = 6:30
Subtract 1 hours
5 : 30 pm
Subtract 45 minutes
4 :45 pm
They started at 4:45 pm

Answer:
An equilateral triangle is formed.
Step-by-step explanation:
Since you construct two lines of 60° at points P and Q, the two ends of the line, you construct a triangle with two angles as 60°.
Hence, with the knowledge that the angle sum of a triangle is 180°, we can find that the remaining angle is [tex](180\textdegree - 60\textdegree - 60\textdegree)[/tex] = [tex]60\textdegree[/tex].
Therefore, a triangle with all angles at 60° is an equilateral triangle.

The school library received a donation of 42 boxes of books. Each box contains 15-18 books. The library has 10 empty bookshelves. Each bookshelf can hold up to 60 books. Does the library have enough shelf space for all the new books? Explain how you solved the problem.
Answer:
No the school libary doesn not have enough pace for all the books. If the least amount of books came which is 15 books in all of 42 boxes (15*42), it would be 630 books and the school libary shelf can only hold 600 books becuase 10 shelves * 60 books on each shelf is 10*60 which is 600. If the least amount of books can’t even fit then the others wold defietnly not fit.
It takes 2.5 yards of material to make a dress. Harley's Clothing Design estimates that they can produce 48 dresses each week. If there are 52 weeks in a year, how much material will they need to purchase to make dresses for a year?
6,240 yards
150 yards
5,910 yards
2,704 yards
Answer:
The answer is 6,240 yards
Step-by-step explanation:
If there is 48 each week thats basically 48×52 = 2496 which is how many dresses times how many yards per dress(2.5)I get 6240.
Hope this helps!!
Answer:
6240
Step-by-step explanation:
Amount of material it takes to make 1 dress = 2.5 yards
Amount of dresses Harley's Clothing Design will produce each week = 48 dresses
Number of weeks in 1 year = 52
2.5*48= 120
120 yards of material used in 48 dresses in one week.
120*52=6240
Therefore, the store will need to purchase 6240 yards of material in order to produce 48 dresses per week for 52 weeks, which is about 1 year.
Hope this helps!

A rectangular box has a volume of 108 cubic feet. How many cubic yards are in the volume of this box?
Answer:
3.996yd³
Step-by-step explanation:
A rectangular box has a volume of 108 cubic feet. How many cubic yards are in the volume of this box?
Given
Volume of a box = 108ft³
We are to convert the dimension to cubic yards. Using the conversion factor
1 ft³ = 0.0370yd³
108ft³ = x
Cross multiply
1 * x = 108 * 0.0370
x = 3.996
Hence the value in cubic yards is 3.996yd³
Answer:
Since there are 3 feet to a yard, there are $3^3=27$ cubic feet to a cubic yard. Thus, there are $108/27=\boxed{4}$ cubic yards in the volume of the box.

Answer:
The Perimeter of a rectangle will be:
P = 252 in
Hence, option (E) is true.
Step-by-step explanation:
Given the rectangle with the sides
length [tex]l[/tex] = 14-5 inWith [tex]w[/tex] = 7×4 inWe know that the Perimeter of a rectangle can be calculated using the formula
[tex]P = lw[/tex]where l is the length, and w is the width
substituting [tex]l[/tex] = 14-5, [tex]w[/tex] = 7×4
P = (14-5) × (7×4)
P = 9 × 28
P = 252 in
Therefore, the Perimeter of a rectangle will be:
P = 252 in
Hence, option (E) is true.

Tyree plans to use SSS to prove two triangles made from a sheet of paper are the same. Which diagram best supports his plan to use SSS?
Picture below
Answer:
Bottom left choice
Step-by-step explanation:
SSS congruence is side-side-side congruence, which is a method to prove triangles congruent by all three sides of the triangle being congruent. The other choices all involve congruent angles. Therefore, the bottom left choice is the best answer.
Also, notice that the bottom left choice shows which side is congruent to which. All three sides of one of the triangles are shown to be congruent with the corresponding side to the other triangle, therefore, congruent by SSS.
I hope this helps! :)
