You are given a bag with 3 cubes (1 green and 2 white). You put all 3 cubes in a bag and shake the
bag and pick a cube. If you pick a green cube, you get 2 points. If you pick a white cube, you lose 1
point. What is the expected value for the game?
Answers
Answer:
-1 (losing a point)
Step-by-step explanation:
it is a probability question
total possible outcomes= 3
favourable outcome(white) = 2
probability of getting a white is 2/3
probability of getting a green is 1/3
so the expected value of the game will be -1
Josh was planning to rent a recording studio for his band. Find the number of hours for which the cost of renting Studio B would
be the same as renting Studio A.
Studio A can be rented for $380 a day
Studio B can be rented for $60 a day plus $40 an hour.
1. Write an equation to model this problem.
2. Solve the equation showing all your steps.
3. Give the number of hours where the 2 costs are the same.
Answers
Answer:
Solution: (2,200)
Step-by-step explanation:
y is the cost after x hours
A: y = 50x + 100
B: y = 75x + 50
Solution: (2,200)
If the demo takes less than 2 hours to record, then Studio B charges less.
If the demo takes more than 2 hours to record, then Studio A charges less.
If the demo takes exactly 2 hours to record, the studios charge the same.

A recipe for a smoothie for 0.75 pound of strawberries. If Kerry has 3.15 pounds of strawberries, how many batches of the recipe can She make
Answers
Answer:
4 batches
Step-by-step explanation:
To obtain the number of batches of the recipe that can be made ;
We take the divison of the total amount of strawberry by the amount of strawberry required per batch :
Pounds of strawberry per recipe = 0.75 pound
Total pounds of strawberry = 3.15 pound
= 3.15 / 0.75
= 4.2
We round down :
4.2 batches = 4 batches of the recipe can be made

Explanation:
1.) Find the area of the wall:
8 feet x 9 feet = 72 square feet
2.) To find out how many square feet of wallpaper he had at first, add the area of the wall to the wallpaper he has left:
72 square feet + 27 square feet = 99 ft2

What is the volume of this triangular prism? A triangular prism. The triangular base has a base of 28 centimeters and height of 22.4 centimeters. The height of the prism is 18.1 centimeters. 313.6 506.8 5,676.16 11,352.32
Answers
Answer:
The volume of the triangular prism is 5676.16 cm³
Step-by-step explanation:
The area of the triangular base A = bh/2 where b = base = 28 cm and h = height = 22.4 cm.
Now, the volume of the triangular prism, V = area of triangular base, A × height of prism, h'
V = Ah' where h = height of prism = 18.1 cm
So, V = bhh'/2
Substituting the values of the variables into the equation for V, we have
V = bhh'/2
V = 28 cm × 22.4 cm × 18.1 cm/2
V = 14 cm × 22.4 cm × 18.1 cm
V = 5676.16 cm³
So, the volume of the triangular prism is 5676.16 cm³

Johnny measured a city park and made a scale drawing. The soccer field is 6 millimeters wide in the drawing. The actual field is 60 meters wide. What scale did Johnny use for the drawing?
Answers
The scale used by Johnny for the drawing is 1/10. This means that every 1 millimeter on the drawing represents 10 meters in reality.
To determine the scale used by Johnny for the drawing, we need to compare the measurements in the drawing to the actual measurements of the soccer field. We can set up a proportion to find the scale.
Let's denote the scale as x (the ratio of the drawing measurements to the actual measurements). According to the information provided, the width of the soccer field in the drawing is 6 millimeters, while the actual width is 60 meters.
We can put up the following proportion using the scale:
6 millimeters / x = 60 meters / 1
We can solve for x by cross-multiplying and then dividing:
6 millimeters * 1 = 60 meters * x
6 = 60x
Dividing both sides by 60:
6 / 60 = x
1 / 10 = x
Therefore, the scale used by Johnny for the drawing is 1/10. This means that every 1 millimeter on the drawing represents 10 meters in reality.

CE and FI are parallel. Giving reasons prove that DGH is isosceles
Answers

Answer:
∠GDH = ∠GHD = 50°
Step-by-step explanation:
Angles FGD and EDG are alternate interior angles, so are congruent. That means angle EDG is 100°. The angle sum theorem tells us ...
∠EDG = ∠EDH +∠HDG
100° = 50° +∠HDG
50° = ∠HDG
You can find the measure of ∠DHG a couple of different ways. It is an alternate interior angle congruent to ∠EDH, so is 50°. It is one of two remote interior angles that have a sum equal to the exterior angle FGD, so is ...
∠DHG = ∠FGD -∠HDG = 100° -50° = 50°
So, angles DHG and HGD both have measures of 50°. When a triangle has two angles with the same measure, it is an isosceles triangle.
