what is 0.6(r 0.2)=1.8

Answers

Answer 1
Isolate the variable by dividing each side by factors that don"t contain the variable.
r=15
Answer 2

the solution to the equation [tex]\(0.6(r - 0.2) = 1.8\) is \(r \approx 3.2\).[/tex]

To solve the equation 0.6(r - 0.2) = 1.8, we first distribute the 0.6 to the terms inside the parentheses:

0.6r - 0.6(0.2) = 1.8

0.6r - 0.12 = 1.8

Next, we add 0.12 to both sides of the equation to isolate 0.6r:

0.6r - 0.12 + 0.12 = 1.8 + 0.12

0.6r = 1.92

Now, to solve for r, we divide both sides of the equation by 0.6:

[tex]\[ \frac{0.6r}{0.6} = \frac{1.92}{0.6} \][/tex]

[tex]\[ r = \frac{1.92}{0.6} \][/tex]

[tex]\[ r \approx 3.2 \][/tex]

So, the solution to the equation [tex]\(0.6(r - 0.2) = 1.8\) is \(r \approx 3.2\).[/tex]

The probable question maybe:

solve the equation 0.6(r - 0.2) = 1.8

Answer: None of the above.
__________________________
Explanation: At this very moment that I submit this answer, the question given consists SOLELY of the following text:
____________________________________
"Determine which two values the following expression is between. 

√37" 
___________________________
Furthermore, At this very moment that I submit this answer, the answer choices given consist solely of the following (there are no updates, comments, etc.):
__________________
"A. 7 and 8 
 B. 5 and 6 
 C. 4 and 5"
________________
Note, the square root of 36; or √36, is 6. The square root of 49, or √49, is 7.
So, √37 is going to be very close to "6", and a LITTLE bit more than "6" but not much more."  It will be a LOT LESS than "7".

The graph of an absolute value function contains the points (1, 2), (0, 0), and (–1, 2). Shawn thinks the function this graph represents is f(x) = 2|–x|. Brielle thinks the function this graph represents is f(x) = 2|x|. Determine who is correct and explain why.

Answers

Answer:

The absolute value parent function is symmetric with respect to the y-axis.  

The graphs of f(x) = 2|–x| and f(x) = 2|x| are identical because the absolute value of negative x is a reflection across the y-axis.  

If you substitute the three given points into both functions, they produce true statements.

Answers

I hope this helps you




m (DGE)=m (IGJ)


they're interior contrary angle

Answer:

The answer is ∠EGH.

Step-by-step explanation:

In order to determine the correct option, we have to know about adjacent angle.

Two angles are adjacent when they have a common side and vertex (corner point). So in this case, the adjacent angle must have GE or DG common side and the G vertex.

According to the options, the adjacent angle to ∠DGE is:

∠EGH

The other options are not adjacent angles because they do not have a common side.

Finally the correct option is ∠EGH.

Lucas is applying to both Stanford and Cal-poly. The probability that he gets accepted to Stanford is 0.4. The probability that he gets accepted to Cal-Poly is 0.3. The probability that he is accepted to both schools is 0.15.

a) What is the probability that he is accepted to one of the two schools?
b) What is the probability that he does not get accepted at either school?

Answers

Final answer:

The probability that Lucas is accepted to at least one of the two schools is 55%, while the probability that he does not get into either school is 45%.

Explanation:

The subject of the question is probability theory, which is a branch of mathematics. Lucas has a 0.4 chance of getting into Stanford, a 0.3 chance of getting into Cal-Poly, and a 0.15 chance of getting into both. These are independent probabilities because they do not affect each other.

a) To calculate the probability that he gets accepted to at least one of the schools, we add the probabilities of him getting into each school, and then subtract the probability of him getting into both (because we're double counting that scenario). So, that's 0.3 (for Cal-Poly) + 0.4 (for Stanford) - 0.15 (for both) = 0.55, or 55%.

b) In probability theory, the total probability of all possibilities is always 1. So, to find the probability that he doesn't get into EITHER school, we subtract the probability that he gets into at least one school from 1. So, 1 - 0.55 (the answer from part a) = 0.45, or 45%. So, there's a 45% chance that Lucas doesn't get accepted into either school.

what is the quotient when -3^3 +5x+14 is divided by x-2? pleas hurry

Answers

The quotient is -3x² + 3x + 8.

To find the quotient when [tex]\(-3x^3 + 5x + 14\)[/tex] is divided by x - 2, we can use polynomial long division.

The dividend is [tex]\(-3x^3 + 0x^2 + 5x + 14\)[/tex] (since there is no [tex]\(x^2\)[/tex] term) and the divisor is x - 2.

1. Divide the first term of the dividend by the first term of the divisor: [tex]\(-3x^3 \div x = -3x^2\)[/tex].

2. Multiply the divisor by the result of step 1: [tex]\((-3x^2)(x - 2) = -3x^3 + 6x^2\).[/tex]

3. Subtract the result of step 2 from the dividend: [tex]\((-3x^3 + 0x^2 + 5x + 14) - (-3x^3 + 6x^2) = -6x^2 + 5x + 14\).[/tex]

4. Repeat the process with the new dividend [tex]\(-6x^2 + 5x + 14\)[/tex].

Continuing the division process, we find the quotient:

[tex]\[ \frac{-3x^3 + 5x + 14}{x - 2} = -3x^2 + 3x + 8 \][/tex]

So, the quotient is -3x² + 3x + 8.

The expressions equivalent to 10x are 50x/5 and (50/5)x as they both simplify to 10x. The other options do not simplify to 10x. Hence option D and E are correct.

To determine which expressions are equivalent to 10x, we need to simplify each option. Let us consider the options one by one:

A.  50x/5x

To solve this a simple division is required.

⇒ (50x/5x)= 10÷(1) = 10

⇒ 10 is not equivalent to 10x.

B.  10 • 10x - 1

Given that t is the median of the numbers 32, 64, 22, t, 41, 22, and 78, what is the lowest possible value of t?

Answers

the answer is 36.5 because when putting the numbres in order from least to greatest 32 and 41 are the two middle numbers, so you would find the average of those two numbers would be the answer.

Final answer:

The lowest possible value for t as the median of the numbers 32, 64, 22, t, 41, 22, and 78 is 32. This value maintains the order when the numbers are arranged from lowest to highest for t to be the median.

Explanation:

To find the lowest possible value for t given that it is the median of the numbers 32, 64, 22, t, 41, 22, and 78, we first need to arrange the numbers in ascending order.

Since there are seven numbers, the median would be the fourth number when sorted.

To ensure t is the lowest possible median, we sort the remaining numbers excluding t. Thus, we have:

22, 22, 32, 41, 64, 78

The third value is 32, and the fifth value is 41, so for t to be the median, t must be greater than or equal to 32 but less than or equal to 41.

However, since we are looking for the lowest possible value of t, t would be 32, as this is the lowest it can be while still being the median of the sorted list.

The sum of two numbers is 56, and their difference is 10. What are the numbers?

Answers

There are two equations hidden in the language here:

a + b = 56 and a - b = 10.

if you do (a+b) + (a-b) then you get:

(a+b) + (a-b) = 66 = a + b + a - b

The b's cancel, so you get 2a = 66, which means a = 33. You can use this to solve for b in one of the above equations by plugging in a = 33 and figuring out what b has to be. Then you will have your two numbers.
x + y = 56
x - y = 10 so x = y + 10
y + 10 + y = 56
2y +10 = 56
2y = 56 -10
2y = 46
y = 46/2
y = 23

x = y + 10 = 23 + 10 =33

Answer: The numbers are 23 and 33
