Eli's Diner sold 50 milkshakes last week. 60% of the milkshakes had whipped cream on top. How many milkshakes with whipped cream were sold?
Answer:
30 will be the number of milkshakes had whipped cream on top.
Step-by-step explanation:
Total number of milkshakes sold by Eli's Diner last week = 50
As 60% of the milkshakes had whipped cream on top.
Let x be the number of the milkshakes had whipped cream on top.
[tex]x=\frac{60}{100}\times 50[/tex]
[tex]x=\frac{60}{2}[/tex]
[tex]x=30[/tex]
Therefore, 30 will be the number of milkshakes had whipped cream on top.

Find the slope when given the following points
(-3, 2) and (1, 0)
Answer:
slope is = -1/2
Step-by-step explanation:
y2-y1= 2-0= 2
x2-x1= -3-1= -4
2/-4= -1/2
y = -4x + 6
y = -2x - 2
Solve for x and y
Answer:
(4,-10)
Step-by-step explanation:
You set them equal to each other.
You get x=4
Sub in 4 for one of the equations
y=-10
Solve for x in y = -4x + 6.
x = −y/4 + 3/2
Solve for x in y = -2x - 2.
x = −y/2 −1
Nothing can be done with y = -4x + 6 and y = -2x - 2

Given the diagram below. If G is the circumcenter of ABC. DC = 16, GB = 21 and AZ = 19, find each measure.
Answer:
Step-by-step explanation:
Properties of a circumcenter;
1). Circumcenter of a triangle is a point which is equidistant from all vertices.
2). Point where perpendicular bisectors of the sides of a triangle meet is called circumcenter of the triangle.
From the picture attached,
9). AG = GB = GC = 21
10). BC = 2(DC)
= 2×16
= 32
11). By applying Pythagoras Theorem in ΔGFB,
GB² = GF² + FB²
(21)² = GF² + (19)²
441 = GF² + 361
GF² = 441 - 361
GF = [tex]\sqrt{80}[/tex]
GF = 8.9
12). By applying Pythagoras theorem in ΔGDB,
GB² = DG² + BD²
(21)² = (DG)² + (16)² [BD = DC = 16]
DG² = 441 - 256
DG = √185
DG = 13.6

Answer:
$324 for 72 pints$306 for 36 quartslarger size is better dealStep-by-step explanation:
The cost of 72 pints is 72 times the cost of 1 pint:
72 × $4.50 = $324.00 . . . cost of 72 pints
The cost of 36 quarts is 36 times the cost of 1 quart:
36 × $8.50 = $306.00 . . . cost of 36 quarts
__
The price for quart containers is lower, so the larger size is the better deal.

Which relation is a function?

Answer:
A,B,D
Step-by-step explanation:
a case bottle water contains 24 bottles . each case contains a total of 405.6 ounces of water wich equation represents the relationship between ounces of water , y,and number of bottles,x
Answer:
y = 16.9x
where y is the ounces of water
and x is the number of bottles
Step-by-step explanation:
Here, we want to find the relationship between ounces of water y and number of bottles x
From the question, we can find the amount of liquid in each bottle
Mathematically, that will be 405.6/24 = 16.9 ounces
There is 16.9 ounces of water per bottle
So the relationship we want to write is that;
y = 16.9x

Buddy and his team have been asked by NASA to make a space shuttle cake (a scale model shaped like the one to the left) for a fundraising event. The original space shuttle has a height of 184 ft and a wingspan of 78 ft. Buddy and his team decide to construct the cake on-site so that they do not have to worry about transporting it. Buddy decides to make a cake with a wingspan of 10 ft and asks one of his decorators, Ivette, to calculate the height of the cake. Ivette decides that the cake should be approximately 4 ft tall.
Answer:
Ivette is wrong and by a lot. The spaceship should be 23.59 feet high
Step-by-step explanation:
The relationship between the spaceship's height and width = 184 feet : 78 feet ≈ 92 : 39 ≈ 9.2 : 3.9. This means that for every 3.9 feet wide, the cake should be 9.2 feet high.
In this case, the spaceship is 10 feet wide, so it should be (10 / 3.9) x 9.2 = 23.59 feet high.
When you make scale drawings or scale cakes, you must keep the same proportions as the original model.
Exercise 1: Which of the following is not an equation

Answer:
(3) 3(2x +1 )
Step-by-step explanation:
For (1), (2), and (4), all of them give an answer while (3) does not which means that (3) is not an equation.
