If t = 20u and r= 5u/2 , which of the following is equivalent to 3rt, in terms of u?
A) 50u^2
B) 150u^2
C) 200u^2
D) 300u^2
Answer:
B
Step-by-step explanation:
t = 20u
r = 5u/2
3rt = 3((20u)(2.5u))
3rt = 3(50u)
3rt = 150u
The value for the expression 3rt is 50u².
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
We have t = 20u and r= 5u/2.
We have to find the value of 3rt by putting the value of t and r as
3rt
= 3 (5u/ 2) (20u)
= 5u x 10u
= 50 u x u
= 50 u²

A box contains 6 red index cards, 3 yellow index
cards, and 4 green index cards. If Gabriella pulls out
2 cards at random from this box, without replace-
ment, what is the probability that both cards are
not green?
Answer:
11/15 = 73%
Step-by-step explanation:
because in total there are 15 cards and 4 of them is not green. You would want to see what is the probability of other colored carded after leaving out the green ones.
The probability that both cards drawn from the box are not green is 27/52.
To determine the probability that both cards drawn from the box are not green, we need to calculate the probability of each individual draw and multiply them together.
Initially, the box contains a total of 6 red index cards, 3 yellow index cards, and 4 green index cards.
For the first draw, there are a total of 13 cards in the box. Since we are interested in the probability of not drawing a green card, there are 13 - 4 = 9 non-green cards. Therefore, the probability of not drawing a green card on the first draw is 9/13.
For the second draw, there will be 12 cards left in the box. Since one green card has already been removed, there are now 12 - 3 = 9 non-green cards remaining. Thus, the probability of not drawing a green card on the second draw is 9/12.
To find the overall probability, we multiply the probabilities of each individual draw:
(9/13) * (9/12) = 27/52

A new car sells for $25,000. The value of the car decreases by 15% each year. What is the approximate value of the car 5 years after it is purchased? 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093 25,000 minus 1500 (5), or approximately $17,500 25,000 (0.15) Superscript 5, or approximately $18,984 25,000 minus left-bracket (100 minus 15) (5) Right-bracket, or approximately $24,575
Answer:
A. 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093
Step-by-step explanation:
A. 25,000 (1 minus 0.15) Superscript 5, or approximately $11,093
B. 25,000 minus 1500 (5), or approximately $17,500
C. 25,000 (0.15) Superscript 5, or approximately $18,984
D. 25,000 minus left-bracket (100 minus 15) (5) Right-bracket, or approximately $24,575
Value of the car = $25,000
Percentage decrease per year = 15%
Value after 5 years
Total percentage value of the car = 100%
Percentage value remaining each year = (100% - 15%)
= (1 - 0.15)
Decrease of the car in the next 5 years = $25,000(1 - 0.15)^5
= $25,000(0.85)^5
= $25,000(0.4437053125)
= $11,092.6328125
Approximately = $11.093
Value of the car in the next 5 years = $25,000 - $11,093
= $13,907
Answer:
It's A, $11,093

Given triangles MNP and QRP are similar triangles, and side MN equals 16 in and QR equals 48 in, what is the scale factor of the dilation from triangle MNP to QRP? "
Answer:
Scale Factor 3
Step-by-step explanation:
According to the Question,
Given That, triangles MNP and QRP are similar triangles, and side MN equals 16 in and QR equals 48 .Therefore, the scale factor of the dilation from triangle MNP to QRP is
Scale Factor = QR/MN ⇒ 48/16 ⇒ Scale Factor 3Find the value of x and y from the equation
Answer:
x = 5 and y = 3
Step-by-step explanation:
5x - 3y = 16
3x - y = 12 multiply second equation by (-3)
(-3)*(3x-y) = 12*(-3) (remember we need to multiply both sides of the equation)
-9x + 3y = -36 now subtract this from the first equation
5x - 3y -9x + 3y = 16 - 36 (-3y will eliminate +3y)
-4x = -20 and 4x = 20 divide both sides by 4
x = 5 if 3x - y = 12 then 3*5 - y = 12
15 - y = 12
-y = -3 and y = 3

Evan, James, and Burt are fishing in a lake that has 200 fish. They are going to be fishing for three hours. What is the probability that they each will catch 3 fish?
Answer:
The probability that they each will catch 3 fish is 0.000063956
Step-by-step explanation:
The hyper geometric distribution is used to solve this as it has a population, a sample , number of successes for both the population and sample.
Here
Population size= N =200
Sample size= n =9= (3*3)
Number of successes in population = k = 3 hours
Number of successes in sample = x= 3
Applying the hyper geometric distribution
P (x=3) = kCx *(N-k) C (n-x)/ N Cn
= 3 C 3 * 197 C 6/ 200 C 9
=0.000063956
The probability that they each will catch 3 fish is 0.000063956

A client has two refrigerators, one in the kitchen and one in the basement.The former is new and efficient. The latter is 30 years old and uses 120Kwh/month. If this client pays 0.15/kwh
Incomplete question: we assume figures to explain further
Answer and explanation:
Given that client pays $0.15/kwh
If old fridge is inefficient and consumes 120kwh/month
And new fridge is efficient and therefore consumes 50kwh/month
For the old fridge, client will be paying
120×0.15= $18 per month on electricity charges
For the new fridge, client will be paying
50×0.15= $7.5 per month on electricity charges

Step-by-step explanation:
Multiplying the second equation by 10, we get 10b+10g=7080.
Subtracting this from the first equation, we get that 5b = 1560, and thus b=312.
Thus, g=396.
