For every 6 students who purchase a bag of M&M’s, there are 5 students who purchase a pack of gum. Use M for the number of students purchasing bags of M&M’s and G for the number students purchasing packs of gum, write an equation for this statement.
Answer:
M/6 = G/5
Step-by-step explanation:
We are given a relation between the numbers of students in two different groups. That relation can be used to write an equation.
Groups who bought M&Ms
If we consider M&M buyers to be 6 in a group, then the number of those groups is ...
M/6
Groups who bought gumSimilarly, the number of groups who bought gum will be ...
G/5
where there are 5 gum-buyers in each group.
EquationThe problem statement tells us that for each group of one kind, there is a matching group of the other kind. That is, the numbers of groups are equal:

Problem 10-09 (Algorithmic) Cress Electronic Products manufactures components used in the automotive industry. Cress purchases parts for use in its manufacturing operation from a variety of different suppliers. One particular supplier provides a part where the assumptions of the EOQ model are realistic. The annual demand is 5,300 units, the ordering cost is $70 per order, and the annual holding cost rate is 25%.
The economic order quantity is 385 and reorder point is 254.
Economic order quantity (EOQ)a. Economic order quantity (EOQ)
EOQ=√2×D×C÷H
Where:
D =Annual Demand
S = Cost of Ordering
H=Holding cost
Hence:
EOQ=√2×5300×70÷.25×20
EOQ=√742,000÷5
EOQ=√148,400
EOQ=385
b. Reorder point

How can we write an algebraic expression to describe a two digit number whose unit's digit is 5
ess than the ten's digit?
Let's x be ten's digit
Answer:
required expression = 11x-5
Step-by-step explanation:
We have information about the following things :
Its a two digit numberUnits digit is 5 less than the tens digittens digit is xSince units digit is 5 less than the tens digit, then the unit digit will become
x-5
Now we have these two things:
Tens digit is xUnits digit is x-5Now let us look at some two digit numbers like 29 , 43 and 78
in 29, tens digit is 2 and units digit is 9
29 is formed by multiplying the tens digit by 10 and multiplying the units digit by 1 like this : 29 = (2×10) + (9×1)
Similarly;
43 = (4×10) + (3×1)
78 = (7×10)+(8×1)
Now to get out two digit number from the question, we similarly need to multiply the tens digit with 10 and units digit with 1 and add them like this:
tens digit : x
Units digit : x-5
Hence the number is (x × 10) + [(x-5)×1] = 10x + x-5 = 11x-5
hence the required algebraic expression is 11x-5

Volume (to the nearest tenth)
Answer:
913
Step-by-step explanation:
cylinder:
radius=5.6 height=7
first lets find the volume of the cylinder the formula for the volume of a cylinder is pi times radius squared times height. so after plugging in the height and radius you get 689.64242
cone:
radius=5.6 height=6.8
now the volume of the cone, the formula for the volume of a cone is pi times radius squared times height/3. so after plugging in the height and radius of the cone you get 223.31278
so 689.64242 + 223.31278= 912.9552 and that rounded to the nearest tenth is 913

The measure of arc ECF in circle G is 98°. The correct option is the second option 98°
Circle GeometryFrom the question, we are to determine the measure of arc ECF
By using the one of the circle theorems
The angle subtended by an arc of a circle is twice the angle it subtends anywhere on the circle's circumference
In the given diagram,
∠F = 1/2 ×104°
∠F = 52°
∠D + ∠E + ∠F = 180° (Sum of angles in a triangle)
∠D + 79° + 52° = 180°
∠D = 180° - 79° - 52°
∠D = 49°
m arc ECF = 2 × m ∠D
m arc ECF = 2 × 49°
m arc ECF = 98°

A sample of size 400 has mean =6.0. Can it be regarded as a sample from a large population with mean 6.25 inches and standard deviation 2.25 inches ? using α=0.05
The value of Z at the 5% level is not significant if the sample of size 400 has mean is 6.0.
What is the standard deviation?It is defined as the measure of data disbursement, It gives an idea about how much is the data spread out.
[tex]\rm \sigma = \sqrt{\dfrac{ \sum (x_i-X)}{n}[/tex]
σ is the standard deviation
xi is each value from the data set
X is the mean of the data set
n is the number of observations in the data set.
The standard error of the estimated mean:
[tex]\rm = \dfrac{2.5}{\sqrt{400}}[/tex]
= 0.1125
x = 6.0–6.2 = 0.2
[tex]\rm Z = \dfrac{0.2}{0.1125}[/tex]
Z = 1.778
This is not significant at the 5% level.
This would have been significant at the 5% level if the same sample means had been found using a sample size of merely 500.

You buy tomatoes in 25 pound cases. One portion of salad requires .75 ounces of tomatoes. How many portions can be made with one
case?
The amount of the portions can be made with one case will be 399.25 ounces.
What is conversion?Conversion means to convert the same thing into different units.
You buy tomatoes in 25 pounds (11.34 kg) cases.
We know that 1 pound (0.45 kg) is equal to 16 ounces (0.45 kg).
Then the number of the ounces in 25 pounds (11.34 kg) will be
⇒ 25 x 16
Multiply the numbers, then the expression will be
⇒ 400 ounces (11.33 kg)
In 25 pounds of tomatoes, there will be 400 ounces.
One portion of salad requires 0.75 ounces (0.02 kg) of tomatoes.
Then the amount of the portions can be made with one case will be
⇒ 400 – 0.75
⇒ 399.25 ounces
Thus, the amount of the portions can be made with one case will be 399.25 ounces.
