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 is the surface area of the cone in terms of π?
A cone. The diameter of the base is 8 meters and the slant height of the cone is 15 meters.
Answer:
The surface area of the cone is;
68 π m^2
Step-by-step explanation:
Here, we want to get the surface area of the cone
Mathematically, we have this as ;
S.A = π(r^2 + rl)
where r is the radius and l is the slant height
We are given the diameter, but the radius is half of this
d = 8
r = d/2 = 8/2 = 4 m
l = 13 m
S.A = π(4^2 + 4(13))
= π(16 + 52) = 68 π m^2

A gardening store ordered 5,710 potted plants last year. This year, the store ordered 10% fewer potted plants. How many potted plants were ordered this year?
Answer:
5319
Step-by-step explanation:
There are two ways that the answer can be determined
Method 1
Determine 10% of 5710. the answer gotten is subtracted from 57100.1 x 5710 = 571
5710 - 571 = 5319
Method 2
If the plants planted this year are 10% fewer, the plants this year are (100% - 10%) 90% of last year's plant
90% x 5710
0.9 x 5710 = 5319

Which is the solution to the system of equations?2x+y=7 and 3x−4y=5
Answer:
X = 3, Y = 1.
Step-by-step explanation:
X = 3 and Y = 1, because 2 times 3 equals 6, and 6 plus 1 equals 7. So that's for the first one, but now we need to make sure that it's the same value for the other equation. 3 times 3 equals 9, 4 times 1 equals 4, and 9 minus 4 equals 5. So X = 3, and Y = 1. Hope this helped :D

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.

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

Step-by-step explanation:
[tex]180 - (35 \times 2) = \\ = 180 - 70 = \\ = 110[/tex]
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

Answer:
D. [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]Step-by-step explanation:
[tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }[/tex] = [tex]\sqrt[4]{\frac{3x^2}{16y^4}}[/tex] = [tex]\sqrt[4]{\frac{3x^2}{(2y)^4}}[/tex] = [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]Correct choice is D
[tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex] is the simplification of the given expression.
What is simplification?Simplifying procedures is one way to achieve uniformity in job efforts, expenses, and time. It reduces diversity and variation that is pointless, harmful, or unneeded. Parenthesis, exponents, multiplication, division, addition, and subtraction are called PEMDAS. The order of the letters in PEMDAS informs you what to calculate first, second, third, and so on, until the computation is finished, given two or more operations in a single statement.
It is given an expression [tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }[/tex]
Simplifying the given expression using the PEMDAS technique,
[tex]\sqrt[4]{\frac{24x^6y}{128x^4y^5} }\\\\\sqrt[4]{\frac{3x^2}{16y^4} }\\\\\frac{\sqrt[4]{3x^2}}{2y}[/tex]
Therefore, the simplified value of the given expression is [tex]\frac{\sqrt[4]{3x^2}}{2y}[/tex]. Thus, the option D is correct.

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

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.

Ariana bought 5 dozen pears at $36 per dozen . She discovered that 7 were rotten and she sold the rest at $4.50 each . Calculate the profit or loss she made on the sale of all the good pears . don't send in file okay
Step-by-step explanation:
1 dozen = 12 pears
12 pears = $36
1 pear = 36/12 = $3
Total Cost of Pears = No. of pears x price of 1 pear
= (5x12) x 3
= 60 x 3
= $180
Sale of Pears = Price per pear x (Total Pears bought - Rotten Pears)
= $4.50 x (5x12-7)
= $4.50 x 53
= $238.50
Profit/Loss = Sale of Pears - Total Cost of Pears
= $238.50 - $180
= $58.50
Ariana made a profit of $58.50.
Answer:
$58.5 (profit)
Step-by-step explanation:
Ariana bought 5 dozen pears at $36 per dozen.
The value of 1 dozen = $ 36
Her buying amount = $36 * 5 = $180
The value of 1 pear = $ 36/12
= $3
The value of 7 pears= $3 * 7 = $21
She sold the remaining (53) at $4.50 each.
Her, selling amount = $4.50 * 53
= $238.50
Her profit amount = selling amount - buying amount
= $238.50 - $180
= $58.5

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.
