Mackenzie needs to determine whether the rectangles are proportional. Which process could she use? Check all that apply.
A pre-image rectangle has a length of 4 and width of 3. An image rectangle has a length of 2 and width of 1.5.
She could compare the ratios of the sides of the pre-image to the corresponding sides of the image in the proportion StartFraction 3 Over 1.5 EndFraction = StartFraction 4 Over 2 EndFraction.
She could verify that adding the same number to each side in the pre-image does not result in the corresponding side length of the image.
She could verify that multiplying each side in the pre-image by One-half results in the length of the corresponding side in the image.
She could verify that subtracting the same number to each side in the pre-image does not result in the corresponding side length of the image.
She could just notice that all the sides in the pre-image are whole numbers so all the sides in the image should be whole numbers.

B.12.65
C.12.6
D.12.66
pls help me
Answer:
D is the right choice and no you cannot fit the pizza inside the box.
Step-by-step explanation:
D is the answer because to turn 2/3 into a decimal you would divide 2 by 3 and the answer you would get would be 0.66666666666...You would then add 12 to the answer and get 12.6666... Once you get this answer you would round it to the hundredths to get 12.67 but since that is not an option you could use D, 12.66 inches.
Answer:
I believe the answer is D.

Leon is scuba diving at an elevation of −72
feet when his friend signals to come higher to see a sea turtle. Leon makes 3 ascents, each an equal distance, to reach an elevation of −18
feet, where the sea turtle is located.
What was Leon's elevation after his second ascent?
Answer: -36 feet
Step-by-step explanation:
72-18 = 54 feet ascended
54 feet / 3 ascents = 18 feet per ascent
18 feet * 2 ascents = 36 feet
-72+ 36 = -36 feet
What is the approximate number of minutes Avery spends
each day on extracurricular activities?
Answer:
115.2
Step-by-step explanation:
8% equals .08
24 hours x 60 minutes = 1440 minutes
1440 x .08 = 115.2
When in doubt you can check. Do this to each section, add up and make sure you 1440.
Answer:
Avery spends an approximate number of 115.2 minutes each day on extracurricular activities.
Step-by-step explanation:
1 day = 24 hour 60min = 1 hour
24 × 60 = 1440 (1440min in a day)
Extracurricular activities: 8%
\(\frac{8*1440}{100}\) = \(\frac{11520}{100}\) (divide 11520 by a hundred) = 115.2

Step-by-step explanation:
Marita spent $13.0 at the grocery store. She bought pears, kiwis and pineaples. Pears cost $0.50 each, pineapples cost $1.50 each, and kiwis are $0.30 each. how many of each kind of fruit did she buy if she bought 9 more pears than pineapples and 2 fewer kiwis than pears?
Answer:
◘ 12 pears
◘ 3 pineapples
◘ 10 kiwis
Step-by-step explanation:
Let \(x\) be the number of pears bought.
Therefore:
• number of pears = \(x\)
• number of pineapples = \(x - 9\)
• number of kiwis = \(x - 2\)
We know that the total cost was $13.50.
This means if she bought \(x\) pears at $0.50 each, \((x - 9)\) pineapples at $1.50 each, and \((x -2)\) kiwis at $0.30 each, the total would be $13.50.
∴ \([x \times 0.50] + [(x-9) \times 1.5] + [(x-2) \times 0.3] = 13.50\)
Expanding and multiplying:
⇒ \(0.5 x + 1.5x - 13.5 + 0.3x - 0.6 = 13.5\)
Collect like terms:
⇒ \(2.3x -14.1 = 13.5\)
Solve for \(x\):
⇒ \(2.3x = 13.5 + 14.1\)
⇒ \(2.3 x = 27.6\)
⇒ \(x = 27.6 \div 2.3\)
⇒ \(x = \bf 12\)
Therefore, she bought:
• 12 pears
• \(x - 9\) = 12 - 9 = 3 pineapples
• \(x - 2\) = 12 - 2 = 10 kiwis
Marita bought 12 pears, 3 pineapples and 10 kiwis.
What are Arithmetic operations?Arithmetic operations can also be specified by the subtract, divide, and multiply built-in functions.
Let x the number of pears bought,
y the number of pineapples bought,
z the number of kiwis bought,
Given that, Marita bought 9 more pears than pineapples and 2 fewer kiwis than pears,
y + 9 = x
y = x -9 and
z + 2 = x
z = x - 2
We know that the total cost was $13.50.
This means if she bought pears at $0.50 each, pineapples at $1.50 each, and kiwis at $0.30 each, the total would be $13.50.
∴ 0.50x + 1.50y+ 0.30z = 13.50
Substitute the values of y and z in equation,
⇒ 0.50x + 1.50(x -9)+ 0.30(x - 2) = 13.50
Expanding and multiplying terms in equation,
⇒ 0.50x + 1.50x -13.50+ 0.30x - 0.60 = 13.50
Rearrange the like terms and apply the arithmetic operation
⇒ 2.3x - 14.1 = 13.50
⇒ 2.3x = 13.50 + 14.1
⇒ 2.3x = 27.6
⇒ x = 27.6/2.3
⇒ x = 12
Therefore, the number of pears bought = 12
So, the number of pineapples bought = 12 - 9 = 3
And the number of kiwis bought = = 12 - 2 = 10
Hence, Marita bought 12 pears, 3 pineapples and 10 kiwis.

The probability of flipping a coin and having it land on heads is 1/2. If a coin is tossed 4 times, how many times can you expect it to land on heads?
Answer:
we can expect the coin to land on heads 2 times out of 4 tosses.
Step-by-step explanation:
If the probability of flipping a coin and having it land on heads is 1/2, then the probability of it landing on tails is also 1/2.When a coin is tossed 4 times, each toss is an independent event, meaning the outcome of one toss does not affect the outcome of another toss. Therefore, we can use the binomial probability formula to find the expected number of times the coin will land on heads:Expected number of heads = n * pwhere n is the number of trials (4 tosses) and p is the probability of success (1/2 or 0.5 in this case).Plugging in the values, we get:Expected number of heads = 4 * 0.5 = 2
15. The product of two whole numbers is always a whole number. Verify this statement
with two examples.
The product of two whole numbers is always a whole number i.e. if 'a' and 'b' are any two whole numbers, their product will also be a whole number.
The multiplication of any two numbers can be expressed as the repeated addition of one number. So, for example, if we add a whole number to itself again and again, then we will definitely be left with the result of a whole number.
Let's assume
a = 2, b = 3.
a × b = 2 × 3 = 6
This is the same thing as adding '2' three times to itself, which will result in a whole number, which is 6 in this case.
Let's take another example 0 and 7. The product of these numbers is:
a = 0, b = 7
a × b = 0 × 7 = 0
As we know, 0 is also a whole number. Through these examples, we can understand that the product of two whole numbers is always a whole number.

Answer: Yes, the product of two whole numbers is always a whole number.
Step-by-step explanation:
Example 1:
Let's take the whole numbers 4 and 3.
The product of 4 and 3 is 12, which is also a whole number.
4 x 3 = 12
Example 2:
Now let's take the whole numbers 7 and 2.
The product of 7 and 2 is 14, which is also a whole number.
7 x 2 = 14

Answer:
A = plane
B = whale
C = sunken ship
Step-by-step explanation:
The given vertical number line is modelling the positions of objects and animals in relation to sea level.
Sea level is the average height of the surface of the world's oceans, which we use as a reference point to measure the elevation and depth of land and water features on Earth.
From inspection of the given number line:
Position A is above sea level.Position B is just below sea level.Position C is the furthest below sea level.We have been told that a plane is flying at 8,500 feet above sea level. Therefore, as position A is the only position above sea level, A = plane.
We have been told that a sunken ship is resting at 3,000 feet below sea level, and that directly above the ship, a whale is swimming 1,960 feet below sea level. Therefore, the whale is above the ship. As position B is above position C, this means that B = whale and C = sunken ship.
