A student said that 42% of 78 is 45. Is this answer reasonable? Explain.
whats the sample response for edg
Answer:
nope
Step-by-step explanation:
.42*78 is 32.76, not 45
Answer:
42% can round to 40%, and 78 can round to 80. 40% of 80 is 32, so 42% of 78 should be about 32. 45 is much greater than 32, so the answer is not reasonable.

Optional question for brainliest: The quotient of a number y and - 3.6 is less than 6.5
Answer: Expert Answer quotient is a mathematical operation requiring two things, i.e. the quotient of a and b is a ÷ b, or a/b. In this case, the problem mentions y / (-3.6) and goes on to say < 6.5. So you have this inequality: y / (-3.6) < 6.5. or equivalently y > - 117/5.
9.8 - b > -4

A = pi • 8^2
Step-by-step explanation:
The formula for area of a circle as A = pi • r^2. Radius is half the diameter, and the given diameter is 16 - therefore, the radius is 8. You then have to raise it to the second power and multiply it by pi to get the area of the circle. Hope this helped! Best of luck.
Answer:
The ameliorated retort, concerning the contemporaneous presented interrogate, is equated to an equation equivalence of B. A= π * 8^2
Step-by-step explanation:
To convey the ideology and retort proposed, the imminent is evaluated.
- To commence, the beginning of the interrogate states the figure obtains a diameter configuration of 16 inches.
- In addition, the radius, given which the diameter is equivalent to such, is obligated to equal 8 inches (r = 1/2(d)).
Furthermore, the precedent may be equated as the following:
A=πr^2
A= π * 8^2, whom is expressed to the unit of A = π * 64
Alas, in conclusion, the voracious retort, subject to the interrogate is equivalent to A = π * 8^2, A = π * 64, or "B."
I hope this helps.

41.11m
Step-by-step explanation:
You're looking for the hypotenuse of a right triangle, so you'll use the pythagorean theorem of a^2 + b^2 = c^2. And here, you're looking for c^2
(18)(18) + (36)(36) = c^2
324 + 1296 = c^2
1690 = c^2
c = square root of 1690 = 41.1096095, round to 41.11
Answer:

For a suitcase to be checked on a flight (instead of carried by hand), it can weigh at most 50 pounds. Andre’s suitcase weighs 23 kilograms. Can Andre check his suitcase? Explain or show your reasoning. (Note: 10 kilograms ≈≈ 22 pounds)
Answer:
No, I don't think so.
Step-by-step explanation:
If his suitcase weighs 23 kg and 10 kg is 22 pounds. You could seperate it. 10, 10, and 3 meaning 22+22= 44. This would mean that 1 kg would equal about 2.2 a pound. So 44 + ( 2.2 x 3 ) = 50.6 kg.
It would be 0.6 k.g over. I think this is right unless I calculated this wrong.
Andrew can not check his suitcase and it needs to remove some items or repack it in order to reduce the weight.
What are Units ?To measure and compare various things we use one term which is known as a unit.
For example, for length measurement we use units like:- metre, centimetre, inch, miles.
To determine if Andre can check his suitcase, we need to convert the weight of his suitcase from kilograms to pounds since the weight limit for checked luggage is given in pounds.
Given that 10 kilograms ≈ 22 pounds, we can convert Andre's suitcase weight of 23 kilograms to pounds by multiplying it by the conversion factor:
23 kilograms x 22 pounds/kilogram ≈ 506 pounds
Therefore, Andre's suitcase weighs approximately 50.6 pounds, which exceeds the weight limit of 50 pounds.
Therefore, Andre cannot check his suitcase and needs to remove some items or repack it to reduce the weight below the weight limit.

Answer:
4x² + 4x + 8
Step-by-step explanation:
P = 2( 2x² - 3x + 1 ) + 2( 5x + 3 ) = 4x² - 6x + 2 + 10x + 6 = 4x² + 4x + 8
4x² + 4x + 8
Answer:
4x^2 + 4x + 8.
Step-by-step explanation:
Perimeter = 2(width + length)
= 2(5x + 3 + 2x^2 - 3x + 1)
= 2(2x^2 + 2x + 4
= 4x^2 + 4x + 8.

The perimeter of a rectangle is 76cm.
Its longest side has a length of 29cm.
State the length of the shortest side.
Answer:
The length would be 9cm
Step-by-step explanation:
Because the perimeter is 76, you have to add 29 to 29 which equals 58, then you have to subtract 58 from 76, which is 18. The last episode is divide 18 by 2 because re are two sides remaining. So answer would be 9. To check the answer you can add 29+29+9+9

What does reduce mean and which scale factor could be an example of a reduction?
Answer:
The scale factor describes the size of an enlargement or reduction. For example, a scale factor of means that the new shape is twice the size of the original. Reduce means to make smaller, to lessen a amount.
Step-by-step explanation:
An example of a scale factor of reduction is 1:25
Enlarging scale means that the drawing is larger than the actual object. Hence the representative fraction will be greater than unity. For reducing scale the representative fraction is less than unity.
So now looking at 1:25, we see it's a reduction scaling because it's fraction is less than unity.
And what 1:25 means is that 1 on paper while the actual size of the object is 25

Sue knitted a scarf for her friend June that was also 4 feet long. After a month, the length of June's scarf could be represented by the expression 3/3 x 4. How did the length of June's scarf change? Explain.
Answer:
There was no change in the length of June's scarf, that is, the length of it remained the same.
Step-by-step explanation:
Since Sue knitted a scarf for her friend June that was also 4 feet long and, after a month, the length of June's scarf could be represented by the expression 3/3 x 4, to determine how did the length of June's scarf change you must perform the following calculation:
Month 1 = 4
Month 2 = 3/3 x 4 = 1 x 4 = 4
Therefore, as can be seen, there was no change in the length of June's scarf, that is, the length of it remained the same.

Because 25+38=63 and 63/7 is equal to 9.
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The value of c in the expression (c + 38) / 7 = 9 is 25.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example:
2 + 3x + 4y = 7 is an expression.
(3x + 2)/ 3 is an expression.
2x + x + 4x is an expression.
We have,
(c + 38) / 7 = 9______(1)
We will solve for c.
From (1).
(c + 38) / 7 = 9
Multiply 7 on both sides.
7 x (c + 38) / 7 = 7 x 9
c + 38 = 63
Subtract 38 on both sides.
c + 38 - 38 = 63 - 38
c = 25
Thus,
The value of c in the expression (c + 38) / 7 = 9 is 25.

Answer: x = 110
Explanation:
We can see that both the sides are equal because of the lines on the sides of the triangle. That means that the angle on the other side is also 35, we also know that the total amount of degrees in a triangle is 180
So now we can do this equation:
35 + 35 + x = 180
70 + x = 180
x = 110

The sum of internal angles of a triangle is 180 and we have a triangle with 2 lengths that are the same. We can say that also the other angle is 35,so the result is 110
