In a group of 28 students, 6 study both Art and Biology.
1 studies Biology but not Art.
1 studies neither subject.
Given that a randomly selected student studies Art, what is the probability the student studies Art and Biology?
Answers
Answer:
3/13
Step-by-step explanation:
There are 28 students. 1 studies biology but not art. 1 studies neither subject. Therefore, there are 26 students who study art.
Of the 26 students who study art, 6 also study biology. So the probability is 6/26, which reduces to 3/13.

D) -0.45, -1/2, 7/12, -2/3, 0.82
Answers
Answer:
c
Step-by-step explanation:
a has a positive before negative, so its ruled out
1.3 is more than -0.45, so b is ruled out
everything in c is in the right order. -1/2 is -0.5 and -2/3 is -0.66, 7/12 is -.58

1. George works for a tech company. He has worked there for 5 years. He makes
$81,536 a year. He started with 8 days of paid vacation time. For each year he works at
the company he gains another three days of paid vacation to a max of 30 days.
a. How many paid vacation days does he now have?
Answers
Answer:
George now has 20 paid vacation days
Step-by-step explanation:
The given parameters are;
The number of years George has worked for the tech company = 5 years
The amount George makes annually while working for the company = $81,536
The starting amount of paid vacation time George has each year = 8 days
The annual increase in the amount of paid vacation time George has each year = 3 days
The maximum number of days of paid vacation allowable = 30 days
a. The number of paid vacation days George now has is given as follows;
The first year George had 8 days paid vacation
The next year George had 8 + 3 = 11 days paid vacation
The third year George had 11 + 3 = 14 days paid vacation
The fourth year George had 14 + 3 = 17 days paid vacation
The fifth year George had 17 + 3 = 20 days paid vacation
Therefore, George now has 20 paid vacation days.
find the measure of the missing angles
b=
c=
Answers
Answer:
b=20
c=160
Step-by-step explanation:
b has the same measurement as the other angle that is across from it. c is 160 because the line that c is on is a straight line so it is 180 degrees, you subtract the other angle on the line,20, then you get the answer.
Answer:
b = 20° ( vertically opposite angles are equal)
b + c = 180°
=> 20 + c = 180
=> c = 180 – 20
=> c = 160°
A bird goes from a higher location to a lower location at a
rate of 2 meters per second,
Which equation models the change in the bird's position at 30 seconds?
A. (-30)(-2) = -60
B. 30(-2) = -60
C. 30.2 = 60
D. 30(-2) = 60
Answers
Answer:
30(-2) = -60
Step-by-step explanation:
The change in speed from a higher location to a lower location is 2 m/s, v = -2 m/s (from higher to lower)
We need to find the equation that models the change in the bird's position at 30 seconds.
Distance = speed × time
change in position = (-2) × 30
= -60
Hence, the correct option is (B).

A sample of paint contains 3 ounces of blue paint and 8 ounces of yellow paint. If you have a 24 ounce can of the blue paint, how much yellow paint should you mix with it in order to make the same color as the sample? (Your answer should have numbers and units)
Answers
Answer:
64 ounces
Step-by-step explanation:
Given.
Represent blue with b and yellow with y
b = 3
y = 8
Required
What's the value of y when b = 24
Represent the given and required parameters as ratio
3 : 8 and 24 : y
Turn the ratio to an equation
3 : 8 = 24 : y
Represent as fraction
⅜ = 24/y
Multiply both sides by y
⅜y = 24
Make y the subject
y = 24 * 8/3
y = 64
Hence:
64 ounces of yellow paints is required for 24 ounces of blue paints

Jerrod found the hypotenuse of a right triangle with legs 3 ft and 1 ft. Is his answer correct?
c2 = 32 + 12
c2 = 9 + 1
c2 = 8
c = 8
No, he setup the Pythagorean theorem incorrectly.
No, he made an error finding the square root.
No, he subtracted 1 and 9 instead of adding.
Yes, he correctly calculated the length of the hypotenuse
Answers
Answer:
The answer is no he is not correct, here's why.
C) No, he subtracted 1 and 9 instead of adding.
Step-by-step explanation:
Jerrod has found the hypotenuse, with the legs of 3 ft and 1 ft, his process is:
[tex]c^{2}[/tex] = 32 + 12
[tex]c^{2}[/tex] = 9 + 1
[tex]c^{2}[/tex] = 8
c = 8
The legs Jerrod said are 3 ft and 1 ft
so A and B of the formula of pythagorean theorem could be:
[tex]a^{2}[/tex] = (3)[tex].^{2}[/tex]
[tex]b^{2}[/tex] = (1)[tex].^{2}[/tex]
This leads us to:
[tex]3^{2} + 1^{2} = c^{2}[/tex]
which is:
9 + 1 = [tex]c^{2}[/tex]
10 = [tex]c^{2}[/tex]
In this case, Jerrod had calculated wrong by instead of adding he had subtracted.
(I don't know where he got 32 + 12, but other than that his process is correct other than calculation error)
The correct statement for given situation is,
⇒ No, Jerrod made an error to finding the square root.
What is mean by Triangle?Any triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
We have to given that;
Jerrod found the hypotenuse of a right triangle with legs 3 ft and 1 ft.
With steps are,
⇒ c² = 3² + 1²
⇒ c² = 9 + 1
⇒ c² = 8
⇒ c = 8
Now,
We have the steps are,
⇒ c² = 3² + 1²
⇒ c² = 9 + 1
⇒ c² = 8
⇒ c = 8
Clearly, In fourth step we get;
If c² = 8
Then, c = √ 8
But here we have;
⇒ c² = 8
⇒ c = 8
Hence, He made an error finding the square root.
Therefore, The correct statement for given situation is,
⇒ No, Jerrod made an error to finding the square root.

Leo and Vanessa both have a certain amount of money and plan to spend a certain amount each week until they run out. Vanessa starts with $400 and plans to spend $80 every 2 weeks. Leo plans to spend his money half as fast and has the same amount of money as Vanessa after 7 weeks.
Answers
Answer:
Leo started with $260
The balance of Vanessa and Leo after 7 weeks = $120
Step-by-step explanation:
Vanessa started $400
Vanesaa spending rate= $80/2weeks
In a week she would spend=$40/week
In 7 weeks should spend =40*7 = $280
Her balance after 7 weeks is =
$400 - $40 × x
$400 - $280
= $120
Leo spends at half of vanessa’s rate= $20/week
In 7 weeks leo will spend
$20 × x weeks
= 20 × 7 = $140
Since Leo and Vanessa’s balance would be the same after 7 days then leo balance is $120
Hence, the amount Leo started with $120 + $140= $260
In order to confirm your above answer
The Equation can be given as
$400 - $40 ×x = $260 - $20 × x
Where x = 7 weeks
$400 -40x = 260 - 20x
$400 - 40× 7 = $260 - 20× 7
$400 - 280 = $260 - 140
$120 = $120
