Student Council is sponsoring the next school dance. They plan to order 2 cheese pizzas for every 3 pepperoni pizzas they order. How many total pizzas will they order if they plan to order 36 pepperoni pizzas for the dance?
Answer: 60 pizzas
Step-by-step explanation:
From the question, we are informed that the student council plan to order 2 cheese pizzas for every 3 pepperoni pizzas they order.
Since 36 pepperoni pizzas are ordered for the dance, the number of cheese pizzas ordered will be:
= 36 × 2/3
= 24 cheese pizzas
The total pizza ordered will now be:
= Cheese pizzas + Pepperoni pizzas
= 24 + 36
= 60 pizzas

Jack bought 500 shares in Glastonbury Goods at $17.85 per share on January 18, 2015. On January 25, 2017, he sold 300 shares after its price had dropped to $15.25 per share. He bought 250 more shares on January 31, 2017 when the price had fallen to $11.90 a share. He sold all of his stock at $18.00 per share on February 5, 2017. How much of a profit/loss did Jack make over the course of his investment? ____________________ profit or loss
Answer:
$775 profit
Step-by-step explanation:
Here, we want to know how much profit or loss Jack made;
he sold 300 shares at $15.25
Amount lost on this will be;
(17.85-15.25) * 300 = -$780
The number of shares he sold at $18 will be the 250 he bought now, and the 200 left unsold before
So profit now will be;
200(18-17.85) + 250(18-11.9)
= $30 + $1525 = $1555
So he made $1555 and lost $780
The amount of profit made is $1555-$780 = $775

Answer:
853.1 sq ft
Step-by-step explanation:
Total bags of rock = 2 3/4
Each bag will cover 310.2 sq ft
How many square feet will Judy be able to cover if she used all the bags of rocks?
Total Square feet covered = number of bags of rock × area covered by each bag
= 2 3/4 × 310.2 sq ft

World's Finest Coffee (Decaf) is sold by the case where one case contains 48 6-ounce packages. A restaurant uses 36 pounds of this coffee each month. How many cases must be ordered per month?
Answer:
The number of cases to be purchased is 2.
Step-by-step explanation:
Giving the following information:
World's Finest Coffee (Decaf) is sold by the case where one case contains 48 6-ounce packages.
First, we need to calculate how many pounds are in each case.
1 pound = 16 ounces
1 case= (48*6)/16
1 case= 18 pounds
Now, the number of cases required each month:
36 pounds = 18*x
x= number of cases
x= 36/18
x= 2
The number of cases to be purchased is 2.

Given: (DE) is a midsegment of triangle ABC.
Find the value of x and y.
What is the length of (AC)?
Answer:
X=13. y=5 AC=20
Step-by-step explanation:
To do this we first have to find the value of x... giving the fact that DE is a mid segment, We know that the length of BC is double the length of DE this means that the length of BC equals 16. So, to equal 16 x will have to equal 13 so 13 + 3 = 16. Now we will find the value of y. We do this by looking at the length of ae and ec. AE equals EC so now that we know x equals 13 we can do 13 minus 3 equals 10 for AE. since EC has to equal 10 we can do 10 minus 5 which equals 5. We now know that y equals 5. We can now add this all up to find the length of AC. We would do 10 + 10 = 20. Hope this helps!
The length of AC from the diagram is 25
To get the value of x and y, we will use the similarity theorem of a triangle
BC = 2DE
x + 3 = 2(8)
x + 3 = 16
x = 16 - 3
x = 13
Hence BC = 16
From the given figure;
AE/DE = AC/BC
x-3/8 = (x-3+y+5)/x+3
10/8 = 15+y/13
130 = 8(15+y)
130 = 120 + y
y = 10
Get the length of AC
AC = 13-3+10+5
AC = 25
Hence the length of AC from the diagram is 25

The graph of g is a horizontal stretch by a factor of 2 and a translation 2 units up, followed by a reflection in the y-axis of the graph of
f(3) = 8x2 - 6. Write a rule for g. Then identify the vertex.
The vertex is
Answer:
f(x)=8x^2-6
f(x) = a (x -h)2 + k
horizontal stretch by a factor of 2 -> 1/2 x
2 units up -> k = 2
reflection in y axis -> x value is negative
g(x) = 8*(1/2 x)2 - 6 + 2
g(x) = 2 x2 -4
Step-by-step explanation:
The vertex will be at g(x) = 2x² -4.
What is a graph?A graph is the representation of the data on the vertical and horizontal coordinates so we can see the trend of the data. A function is defined as the expression that set up the relationship between the dependent variable and independent variable.
Given that the graph of g is a horizontal stretch by a factor of 2 and a translation 2 units up, followed by a reflection in the y-axis of the graph of
f(3) = 8x² - 6.
f(x)=8x²-6
f(x) = a (x -h)2 + k
Horizontal stretch by a factor of 2 -> 1/2 x
2 units up -> k = 2
Reflection in y axis -> x value is negative.
g(x) = 8 x (1/2 x)² - 6 + 2
g(x) = 2x² -4
Therefore, the vertex will be at g(x) = 2x² -4.

Answer:
Step-by-step explanation:
yes, both are congruent by SAS Postulate
