5 out of 8 bags of m&ms had exactly 32 pieces in them. How many bags out of 40 should have exactly 32 pieces
Name three properties that a square and a rhombus share.
Determine whether quantities vary directly or inversely and find the constant of variation. If 5 bushels of wheat weigh 136 kg, how much do 3.5 bushels of wheat weigh?
Let the bushels of wheat is b and weight of the wheat is w.
We can say that more the bushels of wheat more will be the weight of the wheat.
Hence, the quantities vary directly.
Therefore, we have
[tex]b=kw[/tex], where k is the constant of variation.
Now, we have been given that 5 bushels of wheat weigh 136 kg. Thus, we have
[tex]5=136k\\ \\ k=\frac{5}{136}[/tex]
Thus, the constant of variation is [tex]\frac{5}{136}[/tex]
Now, we have been given 3.5 bushels of wheat. Hence, we have
[tex]3.5=\frac{5}{136} w\\ \\ w=\frac{136\times 3.5}{5} \\ \\ w=95.2[/tex]
Therefore, 3.5 bushels of wheat weigh 95.2 kg

Answer in standard form
What phrase can you use to represent m-4? M less then 4/ 4 less then m/ m plus 4 or 4 less m
The phrase 'm less 4' or '4 less than m' can be used to represent the expression 'm-4'. The other phrases mentioned do not accurately represent the mathematical expression 'm-4'.
Explanation:The phrase that you can use to represent the expression m-4 is 'm less 4' or '4 less than m'. The phrase suggests that we are subtracting 4 from variable m. The phrase 'm plus 4' would be used to represent m+4 and does not apply here. So, in expressing the concept of subtraction in a phrase, we often say things like '4 less than m' which clearly conveys that 4 is being subtracted from m.

a translation 12 units right and 2 units down.
Answer:
A translation 12 units right and 2 units down.
Step-by-step explanation:
Given : Figure A and figure A'.
To find : Which transformation of Figure A results in Figure A'.
Solution : We have given that
Parent Triangle A with coordinates ( -6 ,-3) ; ( -4 ,-5) ; ( -8 , - 4)
Transformed triangle with coordinates ( 6 ,-5) ; ( 8 ,-7) ; ( 4 , - 6)
We can see from the coordinates
( -6 +12 ,-3-2) = ( 6 ,-5)
( -4+ 12 ,-5 -2) = ( 8 ,-7)
( -8 + 12 , - 4 -2) = ( 4 , - 6).
Therefore, A translation 12 units right and 2 units down.
What is the surface area of the right cone Below
WILL MARK BRAINIEST !!
Answer:
Option C
Step-by-step explanation:
Given in the picture is a right circular cone with base radius = 3 units and length = 15 units.
We have to find the surface area of the cone.
The total surface area of the cone is the sum of base area + lateral surface area
Base area = area of a circle = [tex]\pi r^2[/tex]
Lateral area of cone = [tex]\pi rl[/tex] where l = length of the cone.
Hence total surface area
= [tex]\pi r (r+l)\\=\pi (3)(3+15)\\=54\pi[/tex] square units
Option C is the answer.

You spend 60 on clothes and buy 3 dvd movies. your friend spends nothing on clothes and buys 8 dvd movies. you both spend the same amount of money. how much does each dvd movie cost?
Each DVD movie costs $12. This is calculated by setting up and solving an equation where the total spending on clothes and 3 DVDs equals the spending on 8 DVDs, as both parties spent the same amount.
To find out how much each DVD movie costs, we need to set up an equation based on the given information. You spent $60 on clothes and bought 3 DVD movies, while your friend spent $0 on clothes and bought 8 DVD movies. It is given that both of you spent the same amount of money. Let's denote the cost of each DVD movie as x.
The total amount you spent is the cost of the clothes plus the cost of the 3 DVD movies, which can be expressed as $60 + 3x. Your friend spent the cost of the 8 DVD movies, which is 8x. Since both amounts are equal, we have:
60 + 3x = 8x
Solving this equation for x:
Subtract 3x from both sides: 60 = 5xDivide both sides by 5: x = $12Therefore, the price of each DVD movie is $12.
Find the missing term of the geometric sequence. 45 ___ 1620
The missing term in the geometric sequence 45, ___, 1620 is 270.
A geometric sequence is a sequence of numbers where each term after the first is found by multiplying the previous one by a fixed, non-zero number called the common ratio.
Given the geometric sequence: 45, ___, 1620, we need to find the missing term.
Let's denote the missing term as a2 and the common ratio as r. The terms of the geometric sequence are determined by the formula:
an = a1 * rn-1
For our sequence:
The first term, a1, is 45.The third term, a3, is 1620.We express the third term in terms of the first term and common ratio:
1620 = 45 * r2
Solving for r2:
r2 = 1620 / 45
r2 = 36
r = 6
Since the common ratio, r, is 6, we can find the missing second term, a2:
a2 = a1 * r
a2 = 45 * 6 = 270
Thus, the complete sequence is 45, 270, 1620.
