A. The product of two numbers with the same sign is positive.
B. The product of two numbers with different signs is negative.
C. The factors in a product can be grouped in any way without changing the value of the product.
D. The factors in a product can be written in any order without changing the value of the product.
Answer:

Fancy Foodstuffs sells 12 eggs for £3.96.
Which shop's price per egg is better?
A. Max's Market B. Groceries Galore C. Fancy Foodstuffs
Answer:
C - Fancy Foodstuffs
Step-by-step explanation:
A = 6 eggs for £2.16
1 egg = £2.16 / 6 = £0.36
B = 8 eggs for £2.72
1 egg = £2.72 / 8 = £0.34
C = 12 eggs for £3.96
1 egg = £3.96 / 12 = £0.33

Drag each expression to the box where it belongs. Some expressions may not belong to either box.
Answer:
The number of roses in each bouquet = 6

3. Alfonso's friend Dani tells Alfonso that her bloodhound, Ol' Sniffy, lived to be 14.
Based on what you know, do you think this was because:
Alfonso didn't use a good estimation method,
Dani doesn't remember Ol' Sniffy's age correctly, or,
Ol' Sniffy lived an unusually long time?
Justify your answer.
It looks like this question wants you to figure out your answer by looking at the chart to see if it looks reasonable.
The first answer doesn't seem to fit the plot so we know that, that inst right. The second one seems like it could work with the question but we dont have enough info to rule it in or out. The third one seems really off because alot of the dogs on the chart lived to be 14 if they where a good weight.
Answer 2: Dani doesn't remember Ol'Sniffy's age correctly, seem like the best fit.
Hope this helped!
Two lines, C and D, are represented by the equations given below:
Line C: y = x + 14
Line D: y = 3x + 2
Which of the following shows the solution to the system of equations and explains why? (5 points)
Group of answer choices
(6, 20), because the point does not lie on any axis
(3, 11), because the point lies between the two axes
(3, 11), because one of the lines passes through this point
(6, 20), because both lines pass through this point
y=x+14 line 1
y=3x+2 line 2
These are both the equation of lines written in slope intercept form
y=mx+b where m is the slope and the point (0,b) is the y intercept.
The first line has a slope of m=1. The 2nd line has a slope of m=3
Since these lines have different slopes, they are not parallel, thus they will cross at some point. What you have to determine is where the lines cross, which will be a point (x,y) that is on both lines.
We already have y solved in terms of x from either equation so we can use substitution to solve the system.
Since y=x+14 from line 1, put x+14 in place of y in the equation of line 2.
x+14=3x+2
solve for x.
Subtract x from both sides...
14= 3x-x+2
14=2x+2
subtract 2 from both sides
14-2=2x
12=2x
divide both sides by 2
6=x
We now have the x value of the common point. Plug the value 6 in for x in one of the original equations and solve for y.
y=6+14
y=20
These two lines cross at the point (6,20) which is a point the two lines have in common.

A scatterplot shows several points with number of hours watching TV versus weekly wages. The researcher came up with the following equation for the trendline.
Weekly wages = -50.755*(hours of TV watched) + 180.
What is the significance of the slope in the context of this model?
Question 1 options:
The amount of TV someone watches does not impact the money they earn. It will stay the same no matter what.
The more TV someone watches, the less money they will earn.

To make grape juice, water is added to a large cylindrical vat of grapes. If the diameter of the vat is 16 feet, what is the area of the base of the vat? Use 3.14 for π.
Answer:
200.96cm^2 base area
Step-by-step explanation:
Eq of circle area = πr^2
= 3.14 x 8^2
3.14 x 64
200.96cm^2
.
The area of the base of the Vat is 200.96 ft².
Base area of a cylinder:Area = πr²where
r = radius
π = 3.14
The grape juice is added to the large cylindrical vat. The diameter of the grape Juice is 16 feet.
Therefore,
Base area of the cylinder is a circle.
Base area = πr²
diameter = 16 feet
radius = 16 / 2 = 8 feet
Base area = 3.14 × 8²
Base area = 3.14 × 64
Base area = 200.96 ft²
