find the value if k(2,3)is a point on graph of the equation x - ky +8= 0
Answer:
k = 3.33
Step-by-step explanation:
x = 2
y = 3
x - ky + 8 = 0
2 - k(3) + 8 = 0
2 - 3k + 8 = 0
10 - 3k = 0
-10 -10
-3k = -10
k = 3.33
Answer:
x−ky+8=0=k=x/y+8/y
k=2/3+8/3 =3.266

HELP ASAP!!! Please give a step-by-step explanation, or you will be reported!
The table gives the probabilities that orphaned pets in animal shelters in six cities are one of the types listed. The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is _____ %. The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is _____ %. (Round to the nearest hundredth.)
For all the dogs: you have 2.65+2.46+3.67+2.91 = 11.69%
Now, the probability of getting a chihuahua would be 3.44/11.69=0.2942= 24.92
Step-by-step explanation:
there ya go!!
Answer:
The probability that a randomly selected orphan pet in an animal shelter in Austin is a dog is 11.71% .
The probability that a randomly selected orphaned dog in the same animal shelter in Austin is a Chihuahua is 29.37% .
Step-by-step explanation:
2.76% + 2.86% + 3.44% + 2.65% = 11.71%
11.71 / 3.44 = .2937
.2937 = 29.37%

Answer:
z = 24
Step-by-step explanation:
35/30 = 7/6
28/7 = 4
6 x 4 = 24
28/24 = 7/6
Answer:
x = 24
Step-by-step explanation:
All you have to do is cross multiply like this..
30 x 28 = 35 x X
=
x = 30 x 28/35
30 x 28 = 840 / 35 =
24
So x is equal to 24

Guys can u help me asap ?? i need explaination aloong the answer
Answer:
5225 x 5/100 = 261.25
5225 - 261.25 = 4963.75
Step-by-step explanation:
We know that % means a 100 so if they say they allowed a 5% discount then that would be 5/100.
You will take the fraction and multiple it with the original price. It will then give you the discount price, you will then need to subtract the discounted amount from the original sale price which is 5225. Then you will get your final answer.

The sum of 1/3 of a number and 12
Start by assigning a variable name to the "number" -- call it x.
Now write out what they say:
"The product of 1/3 and the sum of a number and 3" -- that's 1/3 times x + 3, or (1/3)(x + 3) or (x + 3) / 3
It's "between negative one and five"
So that means:
-1 < (x + 3) / 3 < 5
So now solve this inequality. First multiply everything by 3.
-3 < x + 3 < 15
Subtract 3 from all the terms:
-6 < x < 12
So the answer is, all numbers between -6 and 12
Answer:
I think it's 16

Step-by-step explanation:
The owner of a tree service has a chainsaw that uses a mixture of 200 ounces of gasoline and 2 ounces of oil. The owner needs to make at least
5 gallons of the oil-gasoline mixture.
If the owner knows that l gallon is equal to 128 fluid ounces, which inequality can be used to determine the amount of oil needed?
Answer:
You need 6oz (or 6.3366oz) of oil for the 5 gallon mixture.
Step-by-step explanation:
First, write down the essentials of this word problem.
The chainsaw uses 200 ounces gasoline (or gas) and 2 ounces oil.
The owner needs 5 gallons (640 ounces) of the mixture.
The chainsaw uses a 202 ounce mixture (200oz gasoline 2oz oil).
The mixture is 0.0099 repeating % oil and 0.9900 repeating % gasoline.
0.0099 (oil) x 640 (final mixture) = 6.3366oz repeating oil needed.
0.9900 (gas) x 640 (final mixture) = 633.6633 repeating gas needed.
This means you need 6.3366oz or 6oz (rounded) for the 5 gallon mixture.
CHECKING WORK:
6.3366 + 633.6633 = 639.99999997
OR ROUNDED:
6 + 634 = 640

Answer:
16.8 cubic centimeters
Step-by-step explanation:
3 cm * 4 cm * 1.4 cm = the volume of the prism
3 * 4 = 12
12 * 1.4
1 + 0.4 = 1.4
12 * 1 = 12
12 * 0.4 = 4.8
12 + 4.8 = 16.8
the volume of the prism is 16.8 cubic centimeters

if $45 is divided into the ratio 4:5 the smaller part is A. $1.50 B.$3.50 C.$4.50 D.$24.50 Asap
Answer:
Step-by-step explanation:
When you do 45 divided by 9 you get 5.
45 / 9 = 5
To figure out what the smaller number (in this the 4) equals,
you have to do 4 times 9 to get 36.
4 * 9 = 36
So your answer is 36.

The population of Metropolis was approximately 2,600,000 people in 2000. The population began decreasing at a rate of 1.1% every year after 2000.
Which function models the population of Metropolis x years after 2000?
f(x)=0.989(2,600,000)x
f(x)=2,600,000(1.011)x
f(x)=2,600,000(0.989)x
f(x)=1.011(2,600,000)x
Answer:
f(x) = 2,600,000(0.989)x

(3ax + 4a) - (9x + 15a)
Answer:
3ax−11a−9x
Step-by-step explanation:
3ax+4a−(9x+15a)
Distribute the Negative Sign:
=3ax+4a+−1(9x+15a)
=3ax+4a+−1(9x)+−1(15a)
=3ax+4a+−9x+−15a
Combine Like Terms:
=3ax+4a+−9x+−15a
=(3ax)+(4a+−15a)+(−9x)
=3ax+−11a+−9x
