Lydia is organizing a cooking competition at her school. She ordered some basic supplies to share among the teams that are competing. The teams will be bringing other ingredients as well.
Lydia decide to provide cheddar cheese for the competition. She buys $4.2 kilograms for $39.90
Part A
She estimates the cost of 1 kilograms of cheese to be $1. Is her estimate Reasonable?
Part B
To find the actual cost of 1 kilograms of cheese, Lydia needs to divide $39.90 by 4.2. How can she change the division problem to an equivalent problem.
Part C
If 7 teams share the cheese equally, How much cheese will each team get?
Lol i know this is alot
Answer: look down ⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️⬇️
Step-by-step explanation: part A no her estimate is not reasonable.
Part B I think she can change it to and equivalent problem by making it 40.00 divided by 4.2 maybe in not sure.

Complete the table below. If it is possible to work out the measure of the angle, write it down and show your method. If it is not possible, explain how you know.
Angle: W X Y Z
Is it possible to find the measure of the angle? If so, what is it?
Explain carefully how you decided.
Answer:
w = 70°
x = 70°
y = 40°
z = 40°
Step-by-step explanation:
Notice that two sides of the figure are parallel to each other according to the arrow marking on both sides. This means that by definition this figure must be a parallelogram. This also means that the two other sides must be parallel as well so that there are also two sets of parallel sides.
There is also a transversal (line that cuts across two lines) of which are parallel, this forms different angles which are corresponding, alternate interior, alternate exterior, and supplementary.
70° at <BDC and w are alternate interior which means that they must be the same measure.
Therefore
w = 70°.
Since a parallelogram consists of 2 equal triangles, and we know that two angles are both 70° given that w is 70°, all interior angles must add up to 180° according to the triangle angle sum theorem. So 70° + 70° + y° = 180°.
140° + y° = 180°
–140° –140
Therefore
y = 40°.
Since angle x is exterior and adjacent of (next to) the two interior angles (70° and y), they are supplementary pairs which means that they add up to 180°, because they form a straight line.
Knowing that y is 40°,
x° + 40° + 70° = 180°.
x° + 110° = 180°
–110 –110
Therefore
x = 70°.
Now since angle z is alternate interior of angle y, alternate interior angles have the same measure by definition.
Given that we already know the measure of y = 40°. z must also be 40°
Therefore
z = 40°.
Answer:
∠W = 70°
∠X = 70°
∠Y = 40°
∠Z = 40°
Step-by-step explanation:
∠W = 70° because they are alternate interior angles
∠Y = 180° - 70° + 70° = 40° because all the interior angles of a triangle add up to 180°
∠X = 180° - 70° - ∠Y = 70°
∠Z = ∠Y + ∠70° - ∠W = 40°

Consider these sample means for the number of weekend hours spent studying for a Monday exam.
A 2-column table with 2 rows. Column 1 is a labeled Sample with entries 1, 2, 3, 4. Column 2 is labeled Sample Mean with entries 8, 5, 6, 4.
Which statements are true? Check all that apply.
The variation in the sample means is less than 5.
The variation in the sample means makes population predictions invalid.
The actual population mean most likely will be between 4 and 8.
The sample means can be used to make predictions about the population mean.
The population mean is greater than 8.

Answer:
the first answer is x < 3
the second answer is 5
the third answer is 8h=96
the fourth answer is 16 miles
the fifth answer is 9 dogs
Answer:
1.) x < 3
2.) x = 5
3.) 8h = 96
4.) 16 miles
5.) 7 dogs
Step-by-step explanation:
1.) 4x < 12
x < 3
2.) 4x - 7 = 13
4x = 20
x = 5
3.) We don't know her hourly pay, so as stated, that's h. She worked 8 hours, which means 8(hours) times the unknown pay rate would equal 96.
4.) 3m + 3 = 51
3m = 48
m = 16
16 miles
5.) 3m - 21 > 0
3m > 21
m > 7
7 dogs

Answer:
900
Step-by-step explanation:
First, you figure out what one hour is worth, (which was 300)
Then, you multiply whatever answer you have by how many hours you need. (In this case, we needed 3 hours so I multiplied by 3)
In the end, the answer was 900. Ratio form: 3:900

Use a net of the square pyramid, if necessary, to find the surface area of the pyramid.
Answer:
27 units squared
Step-by-step explanation:
First, we find the surface area of one of the triangles.
(3*3*0.5)
4.5
Next, we find the surface area of all of the triangles.
(4.5*4)
18
The next step is to find the surface area of the square.
(3*3)
9
The last step is to add the surface areas of the square and triangles together.
(18+9)
27
The surface area of the entire shape is going to be 27 units squared.
