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.

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.
um i am not sure! i really am eed help! happy holidays too.
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

find the measure of the line segment RB
9514 1404 393
Answer:
RB = 16
Step-by-step explanation:
When chords cross, the product of the lengths of the pieces of the chord is the same for all:
RB·RD = RE·RC
RB = RE·RC/RD = 8·14/7 = 8·2
RB = 16

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
I have 86 chocolate chip cookies and 42 sugar cookies what is the greatest number of identical packages that I can make
Step-by-step explanation:
Given that,
No. of chocolate chip cookies = 86
No. of sugar cookies = 42
We need to find the number of identical packages that I can make.
It means we need to find the HCF of these 2 number.
Prime factorization of 86 and 42 as follows :
86 = 2 x 43
42 = 2 x 3 x 7
HCF = 2
Hence, I can make 2 identical packages.
Answer:
Assuming there can only be 2 cookies per identical package, She can make 42 identical packages which contains 2 chocolate chip cookies and 1 sugar cookie.
86 / 2 = 43 chocolate chips cookies
42 / 1 = 42 sugar cookies
With the sugar cookies not having the capability to match the requirements we will assume for this answer that an "Identical Package" is composed of 2 chocolate chip cookies, and a single sugar cookie.
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.

The value of a car depreciates every year ata constant rate, Gary bought a car for $25,000 in the year 2013. If the value of the car is expected to depreciate 15% annually, what can Gary expect for the value of his car in the year 2017?
Answer:
Step-by-step explanation:
15×4(which is the difference in the year)=60%(this is the depreciation percent)
The value of the car in 2017=40/100×25000=$10000

Simplify the expression 0.8+0.65÷0.75
Answer:
1.66 (appx)
Step-by-step explanation:
According to BODMAS rule , we should solve division operation in the expression first , then we'll finish the addition opearation .
[tex]0.65 \div 0.75 + 0.8[/tex]
[tex] = > \frac{65}{100} \div \frac{75}{100} + \frac{8}{10} [/tex]
[tex] = > \frac{65}{100} \times \frac{100}{75} + \frac{8}{10} [/tex]
[tex] = > \frac{13}{15} + \frac{8}{10} [/tex]
[tex] = > \frac{(13 \times2) + (8 \times 3) }{30} [/tex]

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
marking brainiiest Emery makes $15 per hour in addition to 2.25% commission on her sales each week. If her sales were $3,200 last week, how much will Emery be paid if she worked 38 hours?
Answer:
Step-by-step explanation:
Emery is paid 15 dollars an hour and she worked 38 hours
15*38=570 dollars just from the hourly wage
the commission is 2.25% and her sales were 3,200 dollars
(3200*2.25)/100=72
total=570+72=642

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.
