The unit rate for $18 for 24 pounds

Answers

$0.75 a pound. This can be written as 3/4, as well.

Final answer:

To find the unit rate of $18 for 24 pounds, you divide the total cost by the number of pounds, resulting in a unit rate of $0.75 per pound.

Explanation:

The student is asking how to calculate the unit rate of a product that costs $18 for 24 pounds. To find the unit rate, you divide the total cost by the total number of units (in this case, pounds). So, the calculation for the unit rate in this question would be:

$18 ÷ 24 pounds = $0.75 per pound

Thus, the unit rate is $0.75 per pound. This means for every pound of the product, you pay $0.75.

Jim makes the following conjecture: other than 1, there are no numbers less than 100 that are perfect squares and perfect cubes. what is a counterexample that proves his conjecture false?

Answers

The number 64 is a counterexample to Jim's conjecture because it is the square of 8 and the cube of 4. A fast way to solve this problem is to list out the perfect cubes that are less than 100 and check if any of them are also perfect squares. A perfect square is a number which can be written as another number multiplied by itself, and a perfect cube is one which can be written as a number multiplied by itself twice. The perfect cubes less than 100 are as follows: 1*1*1 = 1 2*2*2 = 8 3*3*3 = 27 4*4*4 = 64 Now we can calculate perfect squares until we find one in this list 1*1 = 1 2*2 = 4 3*3 = 9 4*4 = 16 5*5 = 25 6*6 = 36 7*7 = 49 8*8 = 64 We see that 64 is in the list of perfect squares and perfect cubes, so this is a counterexample to Jim's conjecture.

Answer choices:

A and T
WCR and TRA
<-----> WC <----> CR
<-----> WC <----> WT

Answers

A and T are points. On their own, they cannot define a line. So we can rule out choice A

WCR and TRA are angles. For any triple the points do not fall on the same straight line. So we cannot define any lines here. This crosses off choice B

Choice C is the answer because WC does define a line. We only need two points to form a line. Similarly CR does the same job. We draw a line marker with two arrows at each end to be placed over the letters to indicate "line". 

Choice D is similar to choice D; however, it is not the answer because WT is the same line as WC. In other words, WC = WT. We haven't named a new line at all. We're simply repeating ourselves.

Find the quotient: 18,198 / 27 518 608 674 689

Answers

Final answer:

The quotient of dividing 18,198 by 27 is 674, as 27 times 674 equals 18,198, leaving no remainder.

Explanation:

The student has asked to find the quotient of the division of 18,198 by 27. To find the quotient, one would typically use long division. After setting up the long division, it turns out that 27 can be divided into 18,198 exactly 674 times, because 27 times 674 equals 18,198.

To solve this, you would write 18,198 as the dividend and 27 as the divisor. Then you would see how many times 27 can go into 181 (the first three digits of 18,198), which is 6 (since 27 x 6 = 162). You write the 6 above the third digit of 18,198, subtract 162 from 181, and bring down the next digit from the dividend, which is 9, making 198. Now you find how many times 27 can go into 198, which is 7 times exactly since 27 x 7 gives you 189. Subtract 189 from 198, and the result is 9, bringing down the last digit 8 to get 98. Finally, you divide 27 into 98 which is 3 times (since 27 x 3 = 81), subtract 81 from 98 to get 17. Since there are no more digits to bring down, we are left with a remainder of 17. Therefore, the quotient is 673 and the remainder is 17.

Jinni opened a bank account. She deposited $87.60 into her account every month for 10 months. She used $25.60 every month to pay for music classes. After 10 months, she used 1 over 4 of the total money left in her account to go to a summer camp for musicians. What is the total amount of money Jinni spent to go to the summer camp? $64.00 $88.00 $155.00 $620.00.Please help I am on a time limit!!!!

Answers

You want to multiply 87.60 and 25.60 by 10. 87.60x10=876. 25.60x10=256.876-256=620. Then you will take 1/4 of 620 to get the answer 155 is what she paid for lessons.

Answer:

$155.00

Step-by-step explanation:

Jinni deposited $87.60 every month for 10 months, this represents a total of

[tex]\$87.60(10)=\$876[/tex]

But, she used $25.60 every month to pay for music classes, the total money spent is

[tex]\$25.60(10)=\$256[/tex]

So, she has in her bank account

[tex]\$876 - \$256 = \$620[/tex]

Then, she uses 1/4 of the total money left ($620) to go to a summer camp, which is

[tex]\frac{1}{4}(\$620)=\$155[/tex]

Therefore, she spent $155 to go to the summer camp. So, the right answer is the third option.

How fast did Car A travel? (The formula R⋅T=D , where R is the rate of speed, T is the time, and D is the distance can be used.) Enter your answer in the box.

Answers

Let the distance be D miles
Car A:-  D = 2.4R   and for Car B:-   D = 4(R- 22)

therefore 2.4R = 4(R-22)

4R - 88 = 2.4R
1.6R = 88
R =  55mph  Answer

Rate of speed is rate of change of distance with respect to time, If Car A traveled the distance in 2.4 h, and Car B traveled the distance in 4 h.

Car A traveled 22 mph faster than Car B. 55mph fast car A travel.

What is Rate of speed?

Rate of speed is rate of change of distance with respect to time.

Let the distance be D miles

Car A:-  D = 2.4R   and

for Car B:-   D = 4(R- 22)

therefore 2.4R = 4(R-22)

4R - 88 = 2.4R

4R-2.4R=88

1.6R = 88

R =  55mph  Answer

A 20-minute TV program consists of two commercials, each 1 3/4 minutes long, and three equal‐length entertainment segments. How long is each entertainment segment?

Answers

Final answer:

To find the length of each of the three entertainment segments in a 20-minute TV program with commercials, we subtract the total time of the commercials from the total time of the program and divide the remaining time by the number of segments. This gives a length of 5.5 minutes for each segment.

Explanation:

To determine the length of each entertainment segment in this 20-minute TV program, we first need to subtract the total length of the commercials from the overall program length. The two commercials, each 1 3/4 minutes long, add up to 3 1/2 minutes.

20 minutes (total program length) - 3.5 minutes (total commercial time) = 16.5 minutes left for the entertainment segments.

As there are three equal‐length entertainment segments, we simply divide the remaining time by the number of segments:

16.5 minutes / 3 = 5.5 minutes.

Therefore, each entertainment segment is 5.5 minutes long.

#SPJ12

Final answer:

Each entertainment segment is 5.5 minutes long.

Explanation:

To find the length of each entertainment segment, we need to subtract the total time of the commercials from the total duration of the TV program.

The total time of the commercials is given as 1 3/4 minutes each, which is equivalent to 7/4 minutes each.

So, the total time of the commercials is 2 * 7/4 = 14/4 = 3.5 minutes.

Since we know that the TV program is 20 minutes long, the total time of the entertainment segments can be found by subtracting the time of the commercials from the total duration: 20 - 3.5 = 16.5 minutes.

Since there are three equal-length entertainment segments, we can divide the total time of the entertainment segments by 3: 16.5 / 3 = 5.5 minutes.

Therefore, each entertainment segment is 5.5 minutes long.
