_________________________Alma makes 5 cups of her favorite shade of purple paint by mixing 3 cups of blue paint, 11/2 cups of red paint, and 1/2 a cup of white paint. Alma has 2 cups of white paint.
Assuming she has enough red paint and blue paint, how much purple paint can Alma make?
Answer:
8 1/2 cups
Step-by-step explanation:
Add the blue and red cups of paint together to get 8 1/2 cups of paint.
Since we can assume she has enough, the answer is eight and a half cups of purple paint.
Alma can make 20 cups of purple paint.
What is the unitary method?The unitary method is a method in which you find the value of a unit and then the value of a required number of units.
Given here: For every 5 cups of purple paint alma needs to add 1/2 cup of white paint .
Thus with 2 cups white paint she could make 4 batches of 5 cups of purple paint.
Therefore, total number of purple paint cups from 2 cups of white paint is
4×5=20 cupa
Hence, Alma can make 20 cups of purple paint.

The volume of the block of white chocolate fudge is 360 cubic centimeters. The volume of the block of milk chocolate fudge is 504 cubic centimeters. How much longer is the block of milk chocolate fudge than the block of white chocolate fudge?Write your answer as a whole number or decimal. Do not round
Answer:
4
Step-by-step explanation:
The volume of a rectangular prism V is the product of its length ℓ, width w, and height h.
V=ℓwh
ou want to find how much longer the block of milk chocolate fudge is than the block of white chocolate fudge.
First, find how long the block of milk chocolate fudge is. The block of milk chocolate fudge is shaped like a rectangular prism. Its width is 6 centimeters, its height is 6 centimeters, and its volume is 504 cubic centimeters.
To find how long the block of milk chocolate fudge is, ℓ, you can use the formula for the volume of a rectangular prism.
V
= ℓwh
504
= ℓ66
504
= ℓ36 Multiply 6 by 6
506
36
=
ℓ36

= ℓ Simplify
The block of milk chocolate fudge is 14 centimeters long.
Now, find how long the block of white chocolate fudge is. The block of white chocolate fudge is shaped like a rectangular prism. Its width is 6 centimeters, its height is 6 centimeters, and its volume is 360 cubic centimeters.
To find how long the block of white chocolate fudge is, ℓ, you can use the formula for the volume of a rectangular prism.
V
= ℓwh
360
= ℓ66
360
= ℓ36 Multiply 6 by 6
360
36
=
ℓ36
36
Divide both sides by 36
10
= ℓ Simplify
The block of white chocolate fudge is 10 centimeters long.
Subtract to find how much longer the block of milk chocolate is than the block of white chocolate fudge.
14–10=4
The block of milk chocolate fudge is 4 centimeters longer than the block of white chocolate fudge.

13. The value of a boat is depreciating at a rate of 7% per year. In 2004, the
boat was worth $192,000. Find the value of the boat in 2013.
Answer: Depreciating at 7% 100 - 7 = 93%
93% = 93/100 = 0.93
0.93 is your factor of depreciation.
There are 9 years between 2004 and 2013
So, you set 9 as power on your factor
0.93^9
Multiply your original value
$192,000 x 0.93^9
= $99,918.93
This is the value of the boat in 2013.

○ [tex]\displaystyle -6x^2 + 6x + 5[/tex]
Step-by-step explanation:
Since the divisor is in the form of [tex]\displaystyle x - c,[/tex]use what is called Synthetic Division. Remember, in this formula, -c gives you the OPPOCITE TERMS OF WHAT THEY REALLY ARE, so do not forget it. Anyway, here is how it is done:
2| −6 18 −7 −10
↓ −12 12 10
________________
−6 6 5 0 [tex]\displaystyle \hookrightarrow -6x^2 + 6x + 5[/tex]
You start by placing the c in the top left corner, then list all the coefficients of your dividend [−6x³ + 18x² - 7x - 10]. You bring down the original term closest to c then begin your multiplication. Now depending on what symbol your result is tells you whether the next step is to subtract or add, then you continue this process starting with multiplication all the way up until you reach the end. Now, when the last term is 0, that means you have no remainder. Finally, your quotient is one degree less than your dividend, so that −6 in your quotient can be a [tex]\displaystyle -6x^2,[/tex]the [tex]\displaystyle 6x[/tex]follows right behind it, then you end it off with [tex]\displaystyle 5,[/tex]giving you the quotient of [tex]\displaystyle -6x^2 + 6x + 5.[/tex]

Two laser beams originating from the same source pass through a glass cylinder parallel to its base. The arc intercepted by the lasers closest to the source measures 60.

A. )10
B. )20
C. )30
D. (40
The measure of the angle formed by the two laser beams is 20°
What is an angle?
An angle is formed when two or more lines intersect. Acute angles are angles less than 90 degrees, obtuse angles are greater than 90 degrees while right angles are 90 degrees.
The arc intercepted by the lasers closest to the source measures 60. The arc intercepted by the lasers on the other side of the cylinder measures 80. Hence:
The measure of the angle formed by the two laser beams = 80 - 60 = 20°

Use the information in the table to answer the question. A 3-column table has 1 row. The first column is labeled Species with entry Goldfish. The second column is labeled Mean with entry 7 inches. The third column is labeled Standard Deviation with entry 1. 2 inches. What percentage of goldfish will have lengths between 4. 6 inches and 9. 4 inches? 34% 68% 95% 99. 7%.
By Using the Empirical formula we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
What percentage of goldfish will have lengths between 4. 6 inches and 9. 4 inches?According to the empirical rule :
(1) 68% of the measures should come within 1 standard deviation of the mean.
(2 95% of the measures should come within 2 standard deviations of the mean.
(3) 99.7% of the measures should come within 3 standard deviations of the mean.
So we can see in this problem
The mean is 7 inches.
The standard deviation is 1.2 inches.
4.6 = 7 - 2(1.2)
9.4 = 7 + 2(1.2)
The measures are within 2 standard deviations of the mean, hence, 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.
Thus by using the Empirical Rule we found that 95% of goldfish will have lengths between 4. 6 inches and 9. 4 inches.

A diner has collected data about customer coffee-drinking habits. They have calculated that P(cream) = 0. 5, P(sugar) = 0. 6, and P(cream or sugar) = 0. 7. Determine the P(cream and sugar). 0. 4 0. 5 0. 6 0. 7.
Probability of an event is the measure of its chance of occurrence. The value of the probability P(cream and sugar) is given by: Option A: 0.4
What is the addition rule of probability for two events?For two events A and B, we have:
Probability that event A or B occurs = Probability that event A occurs + Probability that event B occurs - Probability that both the event A and B occur simultaneously.
This can be written symbolically as:
[tex]P(A \cup B) = P(A) + P(B) - P(A \cap B)[/tex]
For the considered case, the probabilities are:
P(cream) = 0. 5P(sugar) = 0. 6P(cream or sugar) = 0. 7Thus, we get;
P(cream or sugar) = P(cream) + P(sugar) - P(cream and sugar)
0.7 = 0.5 + 0.6 - P(cream and sugar)
P(cream and sugar) = 1.1 -0.7 = 0.4
Thus, the value of the probability P(cream and sugar) is given by: Option A: 0.4
