Step-by-step explanation:
The probability that both marbles she chooses are blue is 2/15
Given : A bag contains 10 marbles: 4 are green, 2 are red, and 4 are blue. Christine chooses a marble at random, and without putting it back, chooses another one at random.
To find : What is the probability that both marbles she chooses are blue?
Solution :
Total number of marbles = 10
Green marbles = 4
Red marbles = 2
Blue marbles = 4
Probability is favorable outcome upon total number of outcomes.
Probability of getting first marble is blue.
P (first blue marble) = 4/10 = 2/5
Without replacement,
i.e. Blue marble left = 3
Total marble left = 9
Probability of getting second marble is blue.
P (second blue marble) = 3/9 =1/3
The probability that both marbles she chooses are blue is
P (both blue marbles) = 2/5 x 1/3
P (both blue marbles) = 2/15

What is coordinate of a point?
A pair of numbers that describe the exact position of a point on a cartesian plane by using the horizontal and vertical lines are called coordinates. General form of coordinate is (x, y)
From the graph we can see , coordinates of that point where both the lines are intersecting is (4, -3)
Because x coordinate is = 4
and y coordinate is = -3
At the value of x=4, the two lines intersect each other

The angles in this diagram are complementary.
What is the value of x?
(4x )°
(2x + 6)°
Answer:
x=168
Step-by-step explanation:
So basically Complementary are 2 angles that add up to 90°
(2x+6)=90
Move the constant to the right hand side and change its sign
2x=90-6
Substract the numbers
2x=84
Divide both sides by 2
x=42
Than plug in to (4x)
(4)(42)
which is =168
The value of x is 16°
What is complementary angle?"The angles are said to be complementary, if two angles add up to form a right angle that is the sum of the two angles is 90°. They both complement each other".
For the given situation,
The angles are (4x )° and (2x + 6)°, so
⇒[tex](4x )[/tex]° [tex]+[/tex] [tex](2x + 6)[/tex]° [tex]=90[/tex]°
⇒[tex]6x+6=90[/tex]°
⇒[tex]6x=90-6\\[/tex]
⇒[tex]6x=84[/tex]
⇒[tex]x=16[/tex]°

Given acd and abe, what is ab?
Answer:
AB = 8
Step-by-step explanation:
Using the similarity theorem of a triangle;
AC/AD = AB/AE
AC = AB + BC and AD = AE + ED
AB + BC/AE + ED = AB/AE
Substitute the given values
AB+12/15 = AB/6
Cross multiply
6(AB+12) = 15AB
6AB + 72 = 15AB
15AB - 6AB = 72
9AB = 72
AB = 72/9
AB = 8

A seagull is perched in a tree 50 feet above sea level. Directly below the seagull is a trout, swimming 23 feet below sea level. What is the distance between the seagull and the trout?
Answer:
27 feet
Step-by-step explanation:
Let the direction above sea level is positive and the direction below sea level is negative.
Here, a seagull is perched in a tree 50 feet above sea level. Directly below the seagull is a trout, swimming 23 feet below sea level.
It means,
Distance = 50 +(-23)
= 50-23
= 27 feet
Hence, the distance between the seagull and the trout is 27 feet.

A farmer grows x acres of peas and y acres of tomatoes. He has 12 acres available to plant peas and tomatoes. Write an inequality in x and y to satisfy this condition. The number acres of tomatoes planted must not be more then twice the number of acres of peas planted. Write an inequality in x and y to satisfy this condition.
Answer:
Y < 2X
Step-by-step explanation:
Let the acres of land on which pea is to be cultivated is "X" acres and the acres of land on which tomato is to be cultivated is "Y"
It is given that number acres of tomatoes planted must not be more then twice the number of acres of peas planted
Thus, [tex]Y < 2X[/tex]
[tex]X + Y = 12[/tex] acres
[tex]Y = 12-X[/tex] acres
Thus,
[tex]12 - X \leq X\\12\leq 2X\\6 \leq X[/tex]
Let us take X = 6 , Then Y = 13-6 = 6

Under his cell phone plan, Anthony pays a flat cost of $56 per month and $4 per gigabyte. He wants to keep his bill under $70 per month. Write and solve an inequality which can be used to determine xx, the number of gigabytes Anthony can use while staying within his budget.
Answer:
x ≤ 3.5 gigabytes
Step-by-step explanation:
Under his cell phone plan, Anthony pays a flat cost of $56 per month and $4 per gigabyte. He wants to keep his bill under $70 per month.
Let us represent the number of gigabytes = x
Hence, our Equation is:
$56 + $4 × x ≤ $70
56 + 4x ≤ 70
Collect like terms
4x ≤ 70 - 56
4x ≤ 14
x ≤ 14/4
x ≤ 3.5 gigabytes
Therefore, the number of gigabytes Anthony can use while staying within his budget is less than or equal to 3.5 gigabytes
