51 batches
7.5 batches
6 batches
Answers
Answer: 7.5 Batches
Step-by-step explanation:
Plug 45 in for Y:
45/6=6x/6
Isolate variable (divided by 6)
X=7.5
The required number of batches of cookies corresponding to the 45 ounces is 7.5 batches. Option C is correct.
Given that,
The number of ounces of chocolate chips per batch of cookies can be represented with the equation y = 6x, where y represents ounces of chocolate chips and x represents batches of cookies.
proportionality is defined as between two or more sets of values, and how these values are related to each other in the sense are they directly proportional or inversely proportional to each other.
Here,
Given proportionality,
y = 6x
Put y = 45
x = 45 / 6
x = 7.5
Thus, the required number of batches of cookies corresponding to the 45 ounces is 7.5 batches. Option C is correct.

Multiply the pairs of numbers and match them with their products. Tiles (-5)(4.2) (-7)(-3) (4) (5) (2.5)(-9) Pairs 22.5 21 -22.5 -21 111
Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

A scuba diver is 15.5 feet below the surface of the water. If the diver continues to swim downward at a rate of 2.5 feet per second, what is her location, in feet, relative to the surface after 712 seconds? feet
Answers
The answers is: 33
33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.
Step-by-step explanation:
Given:
A scuba diver is 15.5 feet below the surface of the water.
The diver continues to swim downward at a rate of 2.5 feet per second.
Now, to find the integer represents her location relative to the surface after 7 seconds.
And to find how far does the diver have to go to return to the surface.
So, to get the integer represents her location relative to the surface after 7 seconds.
Initial depth = 15.5 feet.
Distance traveled down = 7 × 2.5 = 17.5 feet.
Final depth of water surface = Initial depth + Distance traveled down.
Final depth of water surface = 15.5 feet + 17.5 feet.
Final depth of water surface = 33 feet.
Thus, 33 is the integer represents her location relative to the surface after 7 seconds.
Now, to get how far does the diver have to go to return to the surface:
As, the diver goes to 33 feet down to the surface.
Thus, the diver to return she have to go through the same distance.
So, to return to the surface she need to go to 33 feet far.
Therefore, 33 is the integer that represents her location relative to the surface after 7 seconds.
And 33 feet far the diver have to go to return to the surface.

A cube has a side length of 13 millimeters. What is the surface area of the cube?
Answers
1. To find the difference between the temperatures, we simply subtract the smaller temperature from the larger temperature. In this case, the smaller temperature is -4°F and the larger temperature is 6°F. So the difference between the temperatures is:
6°F - (-4°F) = 6°F + 4°F = 10°F
Therefore, the difference between the temperatures is 10°F.
2. If the Suarez family spends 30% of their income on the house payment, then the remaining 70% of their income is used for other expenses. We can set up an equation to solve for their income:
0.7x = income after house payment
x = total income
We know that the house payment is $1,200, so we can substitute that into the equation:
0.7x = x - 1200
Solving for x, we get:
0.3x = 1200
x = 1200 / 0.3
x = $4,000
Therefore, the family's income is $4,000.
3. Simplifying the expression 2a-2b-4a-1b, we can combine like terms:
2a - 4a - 2b - 1b = -2a - 3b
So the simplified expression is -2a - 3b.
4. To produce a random sample of students, Carlin should use a method that gives each student an equal chance of being selected. One such method is simple random sampling, where each student is assigned a number and a random number generator is used to select the desired number of students. Another method is systematic sampling, where every nth student on a list is selected. However, other methods such as convenience sampling or voluntary response sampling may introduce bias and should be avoided if a truly random sample is desired.
1. To find the difference between the temperatures, we subtract the smaller temperature from the larger temperature: 6°F - (-4°F) = 10°F. Therefore, the difference in temperature is 10°F.
2. If the Suarez family spends 30% of their monthly income on the house payment and the payment is $1,200, we can set up the equation:
0.3x = 1200
Solving for x, we get:
x = 1200 / 0.3 = $4,000
Therefore, the family's income is $4,000.
3. Simplifying the expression 2a - 2b - 4a - 1b, we can combine like terms:
2a - 4a - 2b - 1b = -2a - 3b
Therefore, the simplified expression is -2a - 3b.
4. To produce a random sample, we need to select individuals randomly from the population. Option c, surveying every 15th student who enters the cafeteria at lunchtime, is the only method listed that produces a random sample.
5. Evaluating -8 + 8, we can see that the terms cancel each other out, so the result is 0.
6. To find the total amount Mary spent for the jeans and sweater including sales tax, we can calculate:
Total cost = Cost of jeans + Cost of sweater + Sales tax
Total cost = $30 + $35 + 0.06($30 + $35)
Total cost = $30 + $35 + $3.3
Total cost = $68.3
Therefore, Mary spent $68.3 in total for the jeans and sweater.
7. To find the change in stock value after three days, we can add and subtract the values given:
-1/2 + 3/4 - 3/8 = 1/8
Therefore, the change in stock value after three days is 1/8.
8. To factor the expression using the greatest common factor, we can factor out 4x:
4x(3x - 2) - 2(3x - 2)
= (4x - 2)(3x - 2)
= 2(2x - 1)(3x - 2)
Therefore, the factored expression is 2(2x - 1)(3x - 2).
9. To find the total amount that Nigel pays back after one year, we can use the formula:
Total amount = Principal + Simple interest
Simple interest = Principal x Rate x Time
In this case, the principal is $250, the rate is 5.5%, and the time is 1 year.
Simple interest = $250 x 0.055 x 1 = $13.75
Total amount = $250 + $13.75 = $263.75
Therefore, Nigel pays back $263.75 in total.
10. If the fish's depth is -3/4 mile, the turtle's depth is (1/3)(-3/4) = -1/4 mile. Therefore, the turtle's depth is -1/4 mile.
11. To find the difference between the expressions, we can subtract the second expression from the first:
(2x^2 + 3x - 1) - (3x^2 - 2x + 3)
= 2x^2 + 3x - 1 - 3x^2 + 2x - 3
= -x^2 + 5x - 4
Therefore, the difference of the expressions is -x^2 + 5x - 4.
12. The surface area of a cube is given by the formula 6s^2, where s is the length of one side of the cube. In this case, s = 13 mm, so we can calculate:
Surface area = 6(13^2)
Surface area = 6(169)
Surface area = 1014 mm^2
Therefore, the surface area of the cube is 1014 square millimeters.

Light travels from the sun at 1.12 x 107 miles per minute. The planet, Mars, is approximately 1.42 x 108 miles away from the sun.
What is the approximate amount of time, in minutes, for light to travel from the Sun to Mars? Write your answer in scientific notation rounded to the nearest hundredth.
Answers
Answer:
Time = 1.27 x 10^1 minutes
Step-by-step explanation:
To calculate the approximate amount of time it takes for light to travel from the Sun to Mars, we can divide the distance between them by the speed of light.
Given:
Speed of light = 1.12 x 10^7 miles per minute
Distance between the Sun and Mars = 1.42 x 10^8 miles
Time = Distance / Speed
Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)
Time = (1.42 / 1.12) x 10^(8 - 7) minutes
Time = 1.27 x 10^1 minutes
Rounded to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.70 minutes in scientific notation.
Time = Distance / Speed
Given:
Speed of light = 1.12 x 10^7 miles per minute
Distance from the Sun to Mars = 1.42 x 10^8 miles
Time = (1.42 x 10^8 miles) / (1.12 x 10^7 miles per minute)
To simplify the calculation, we can divide the numerical values and subtract the exponents:
Time = 1.42 / 1.12 x 10^(8 - 7) minutes
Time = 1.27 x 10^1 minutes
Rounding to the nearest hundredth, the approximate amount of time for light to travel from the Sun to Mars is 12.7 minutes in scientific notation.
