@bot answer this
1.) Find the difference. -58 - (-25)*
A. 33
B. -33
C. 83
D. -83
The answer is:
B. -33
@bot
2.) What is the sum of -58 + -45?
A. 13
B. 103
C. -103
D. -13
The sum of -58 + (-45) is -103. So the answer is:

@ bot
3.) Which number is divisible by 3?
*
A.1,345
B.388
C. 5,432
D.1,452
The number that is divisible by 3 is:
D. 1,452
To check if a number is divisible by 3, you can add up its digits. If the sum of the digits is divisible by 3, then the original number is also divisible by 3. In this case, the sum of the digits of 1,452 is 1+4+5+2 = 12, which is divisible by 3.

4.) Tom's goal is to save an average of $55 a week for six weeks. For the first five weeks he saved 45, 60, 25, 50, 55. What is the smallest amount he can save in week 6 to meet his goal?
*
1 point
A. 80
B. 55
C. 95
D. 65
To find out what the smallest amount Tom can save in week 6 to meet his goal, you can use the following formula:
Total savings = (average savings per week) x (number of weeks)
Tom's total goal savings is:
Total savings = $55 x 6 = $330
Tom already saved:
Week 1: $45
Week 2: $60
Week 3: $25
Week 4: $50
Week 5: $55
Total saved in 5 weeks = $235
To meet his goal, Tom needs to save:
$330 – $235 = $95
Therefore, the smallest amount Tom can save in week 6 to meet his goal is:
C. $95

5. ) Write the following in standard form.
*
5.8709x10^7
58, 709
58,709,000
5,870,900
587,090
The standard form is a way of writing a number as a simple numeral with no exponent. To write the number 5.8709 × 10^7 in standard form, we have to multiply 5.8709 by 10 seven times, which means moving the decimal point seven places to the right. So, the answer is:
58,709,000
Therefore, the number 5.8709 × 10^7 written in standard form is:
58,709,000
@bot
6.) Find the quotient.
36.75 divided by 4.2
8.075
8.65
8.705
8.75
Are these still correct?
No, the correct answer is:
8.75.
To solve this problem, you can line up the decimal points of 4.2 and 36.75. Then, you can divide as you normally would:
```
8.75
_______
4.2|36.75
33.6
-----
3.15
```
Therefore, 36.75 divided by 4.2 equals 8.75.
ALRIGHTYYYYYYYYYYYYYYYYYYYY THEY'RE STILL CORRECT
Glad to hear that! Let me know if you have any other questions or if there is anything else I can assist you with.
Suppose you spin the spinner once. Find the probability.
A circle is divided equally into eight sections.· Two of the sections are labeled with an upper B.
· One of the sections is labeled with an upper G.
· One of the sections is labeled with an upper Y.
· Four of the sections are labeled with an upper R.
· An arrow originating from the center of the circle is pointing at one of the sections with an upper R.
P(red or blue)
A. 0
B. one-fourth
C. one-half
D. start fraction 3 over 4 end fraction
Since red and blue are not directly given on the spinner, we can use the information provided to determine which sections can be considered red or blue.
We know that two sections are labeled with "B", and four sections are labeled with "R". Thus, the total number of sections that are either red or blue is 2 + 4 = 6.
The probability of getting a red or blue section can be calculated as the total number of red or blue sections divided by the total number of sections, which is 8:
P(red or blue) = (number of red or blue sections) / (total number of sections) = 6/8 = 3/4
Therefore, the answer is:
D. 3/4

What is the probability that 1 shopper, selected at random, preferred neither Drink E nor Drink C?
A. thirty-five over forty-one
B. thirteen over forty-one
C. twenty-eight over forty-one
D. thirteen over twenty-eight
To find the probability that 1 shopper, selected at random, preferred neither Drink E nor Drink C, we need to add the number of shoppers who preferred drink A, drink B, and drink D, and then divide by the total number of shoppers who took the survey:
Number of shoppers who preferred A, B, or D = 10 + 15 + 3 = 28
Total number of shoppers who took the survey = 10 + 15 + 7 + 3 + 6 = 41
Probability = Number of shoppers who preferred A, B, or D / Total number of shoppers who took the survey
Probability = 28/41
Therefore, the answer is:
C. twenty-eight over forty-one
A farmer examines a sample of 25 cartons of eggs and finds that 3 contain cracked eggs. What is the best prediction of the number of cartons with cracked eggs in a delivery with 500 cartons?
A. 6
B. 12
C. 60
D. 120
If the farmer found that 3 out of 25 cartons contained cracked eggs, we can use this information to make a prediction for the number of cartons with cracked eggs in a delivery with 500 cartons.
The proportion of cartons with cracked eggs in the sample is:
3/25 = x/500
Solving for x, we get:
x = (3/25) * 500 = 60
Therefore, the best prediction for the number of cartons with cracked eggs in a delivery with 500 cartons is 60.
So, the answer is:
C. 60
