Answer:
Step-by-step explanation:
The sin(30) = 1/2
The sin(30) = 1/2 = opposite / hypotenuse
Opposite = 7
hypotenuse = opposite / sin(30)
hypotenuse = 7 / (1/2) = 7 *2 / 1 = 14
The long side can be found using the Pythagorian Theorem.
a^2 + b^2 = c^2
a = 7
b = ?
c = 14
14^2 = 7^2 + b^2
196 - 49 = b^2
147 = c^2
147 = 3*7 *7
sqrt(b^2) = sqrt(3*7*7)
b = 7 sqrt(3)

Find the equation of the straight line passing through the point (0, -1) which is perpendicular to the line y=-3/4 x-3
Answers
Answer:
y = [tex]\frac{4}{3}[/tex] x - 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = - [tex]\frac{3}{4}[/tex] x - 3 ← is in slope- intercept form
with slope m = - [tex]\frac{3}{4}[/tex]
Give the slope of a line m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-\frac{3}{4} }[/tex] = [tex]\frac{4}{3}[/tex]
The line crosses the y- axis at (0, - 1 ) ⇒ c = - 1
y = [tex]\frac{4}{3}[/tex] x - 1 ← equation of perpendicular line

Answers
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%

The sum of 1/3 of a number and 12
Answers
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

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.

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?
Answers
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
