Answer:
perimeter = 1 3/4
Step-by-step explanation:
1. 3/4 x 2 because there are two sides with the fraction 3/4. 3/4 x 2 is 1 1/2
2. 1/8 x 2 because there are two sides with the fraction 1/8. 1/8 x 2 is 1/4
3. 1 1/2 + 1/4 = 1 3/4

-6= -15r+9s. Solve for s
Answers
Answer:
(5r-2)/3 = s
Step-by-step explanation:
-6= -15r+9s
Add 15r to each side
-6+15r= -15r+15r+9s
15r-6 = 9s
Divide each side by 9
(15r-6)/9 = 9s/9
(5r-2)/3 = s

Answers
Answer:
[tex]f(x)=32(1.3)^x[/tex]
Step-by-step explanation:
Here, the growth factor is 1.3 since 32(1.3)=41.6, 41.6(1.3)=54.08, and so on.
Therefore, the function that represents the table is [tex]f(x)=32(1.3)^x[/tex]
A bag contains 4 red marbles, 3 blue marbles and 6 green marbles. If two marbles are
drawn out of the bag, what is the probability, to the nearest 1000th, that both
marbles drawn will be red?
Answers
Answer:
~0.143
Step-by-step explanation:
So, in total there are 15 marbles, and only 6 of them are red. So the first draw will have a chance of being red. Since you didn't mention placing it back, the next draw will have a chance of being red. It's , because you just took a red one out of the bag (leaving 5 left) and the total was lessened by one. To get the answer, you'd multiply both numbers together.
6/15 x 5/14 = 1/7 or (roughly) 0.143
1. The sum of two numbers is 20.5. Their
difference is 6.5. Find the two numbers.
Answers
Answer:
13.5 and 7
Step-by-step explanation:
x + y = 20.5
× - y = 6.5
Hence,
x =20.5 - y
20.5 - 2y = 6.5
Hence,
2y = 14
and x = 20.5 - 20.5 - 7 = 13.5
Hope that helps :))
Answer:
The two numbers are 7 and 13.5
Step-by-step explanation:
Let the two numbers be x and y
Make 3 equations (for system of equation and substitution method)
Equation 1. x - y = 6.5
Equation 2. x = 6.5 + y
Equation 3. x + y = 20.5
Use the value of x in equation 2 to substitute x in equation 3.
6.5 + y + y = 20.5
Combine like terms
6.5 + 2y = 20.5
- 6.5 on both sides
2y = 14
Divide both sides by 2 to isolate y
y = 7
Substitute y in equation 3 to find x
x + 7 = 20.5
x = 13.5
Hope this helps :)

which expression is equivalent to 12^-5 times 12^9?
a. 1/12^-45
b. 12^-45
c. 1/12^4
d. 1/12^-4
Answers
Answer:
D. 1/12^-4
Step-by-step explanation:
[tex]12^{-5}*12^{9}[/tex]
Since both exponents have the same base, we can add the exponents to get:
[tex]12^{-5+9}=12^{4}[/tex]
We can cross out A and B since they multiplied the two exponents, therefore both answers are wrong.
Now, let's try C and D.
C is wrong because it has a different base being raised to the same power.
D is correct. When you have a negative exponent, it is equivalent to the reciprocal of the base to the positive exponent.
The reciprocal of 1/12 is 12, and the positive of -4 is 4, therefore the answer is D.
Answer:
12^14

It's the correct answer

8. 11/12 gallons of paint
10. 23/24 gallons of drink mix
Step-by-step explanation:
Note: When denominators are different, you must find a common denominator between the two fractions by multiplying both values
Ex: 1/3 and 1/4 = 4/12 and 3/12 common denominator is 12
8. Find the common denominator, 3/4 and 1/6, multiple the first denominator, 4, with three to get 12. Now multiply the numerator by the same number. 9/12 is our new fraction. Since the new denominator is 12, we have to get the other denominator to be 12 as well. Multiply 6 from 1/6 by 2 to get 12. Now do the same with the numerator. 2/12 is our new fraction, and all that's left is to add them together to find how much paint Damon has in total, which is 11/12 gallons.
10. Same concept as the above, 1/12 and 7/8 have a common denominator of 24, multiply 1 and 12 by two to get 2 and 24. Multiply 7 and 8 by 3 to get 21 and 24. 2/24 and 21/24 are our new fractions to add together. 23/24 is our answer.

Answers
Answer:
5x^2-8x + 12
Step-by-step explanation:
the formula for finding roots of equation is
x^2- (sum of roots)x + products of roots =0

so we add them to give 8
and multiply to give 12
hence the quadratic equation that has those roots with leading coefficient is 5x^2-8x + 12=0

First option) y= 2x - 3
Step-by-step explanation:
[] The y-intercept, our b, is -3. This does not rule out any of the options as they all have -3.
[] The slope, when we have a graph with clear points, can be found with rise-over-run. We will pick a point and then count up and over to the next point.
-> Starting at the y-intercept, (0, 3), we count up 2 and to the right 1 for a slope of 2/1. This simplifies to 2.
[] Our equation is y = 2x - 3
