Answer:
0.06
Step-by-step explanation:
Total number of marbles:
6 + 10 + 5 + 1 = 22 marbles
Probability of picking 1 red marble:
red marbles / total marbles
6/22
Probability of picking a green marble:
green marbles / total marbles
5/22
Now, multiply the probabilities:
6/22 • 5/22 = 15/242 = 0.06

Answer:
[tex]→1 \frac{2}{3} + 2 \frac{3}{4} \\ = \frac{5}{3} + \frac{11}{4} \\ = \frac{20 + 33}{12} \\ = \frac{53}{12}\\ =\boxed{4\frac{5}{12}}✓[/tex]
53/12 is the right answer.Steps:
1 2/3 + 2 3/4 can also be written as...
5/3 + 11/4
The LCD is 12 so we make both fractions have a denominator of 12.
That gives us 20/12+33/12
Now you can add the numerators (but leave the denominator the same)
That gives us 53/12, but our simplified version would give us 4 5/12 as our final answer.

4. Find the height, x, of the building
Urgent please help
Answer:
D
Step-by-step explanation:
The function you need to use is the Tan(39).
Tan(x) = opposite / adjacent.
The opposite side does not make up the reference angle.
In this case, the opposite side = x
The adjacent side is not the hypotenuse and does make up the reference angle (which is not the right angle).
opposite = x
adjacent = 68
Tan(39) = x / 68 Multiply by 68
68*Tan(39) = x Divide by Tan(39)
Tan(39) = 0.9098
68*.9098 = x
x = 55.07
what is 8 - [tex]\frac{8}{2}[/tex] + [tex]7^{2}[/tex]
Answer:
53
Step-by-step explanation
8 - 8/2 (this is a fraction) is also known as
8-4 because 8 divided by 2 is 4
so 8-4 = 4
next 4 + 7^2
why is the 2 in the air????
so that's called an exponent, in this case the two means 7 x 7, it is multiplying by itself, thats the essence of exponents. I can do this for exponent 3,4,5,6,7 and so forth. Anyways, 7^2 or 7x7=49
Knowing this its now 4+49= 53

Answer:
2/3
Step-by-step explanation:
Let x represent the fraction of Cheryl's income she spent in September. Then 1-x is the fraction she saved.
In October, her spending increased by 0.2x, and her savings decreased by 0.4(1 -x). Since Cheryl spends or saves all of her income, these two change amounts must be equal:
0.2x = 0.4(1 -x)
x = 2(1 -x) . . . . . . multiply by 5 to clear fractions
x = 2 -2x . . . . . . eliminate parentheses
3x = 2 . . . . . . . . add 2x
x = 2/3 . . . . . . divide by 3
Cheryl spent 2/3 of her income in September.

A school store buys pencils in bulk and sells them to students for a small profit. The school pays $2.00 for 100 pencils and sells them for 10 cents each. How many pencils would they have to sell to make a $100 profit?
Answer:
1,000
Step-by-step explanation:
First, there are 10,000 cents in $100.
So divide 10,000 by 10. (because 1 pencil is 10 cents)
1,000.

Please help me to solve this problem of ordered pairs. The value of x and y should be find.
Answer:
x=y=-2
Step-by-step explanation:
Comparing these ordered pairs, we will get
4^(1/x)=1/2 and 9^(1/y)=1/3
x=-2 and y=-2
Answer:
x = y = - 2
Step-by-step explanation:
Using the rule of radicals/ exponents
[tex]a^{\frac{m}{n} }[/tex] = [tex]\sqrt[n]{a^{m} }[/tex] , [tex]a^{-m}[/tex] = [tex]\frac{1}{a^{m} }[/tex] , [tex](a^m)^{n}[/tex] = [tex]a^{mn}[/tex]
Given
[tex]\sqrt[x]{4}[/tex] = [tex]\frac{1}{2}[/tex] , then
[tex]\sqrt[x]{2^{2} }[/tex] = [tex]\frac{1}{2}[/tex]
[tex]2^{\frac{2}{x} }[/tex] = [tex]2^{-1}[/tex]
Since the bases on both sides are equal, both 2 , then equate exponents
[tex]\frac{2}{x}[/tex] = - 1 ( multiply both sides by x )
2 = - x , that is
x = - 2
Similarly
[tex]\sqrt[y]{9}[/tex] = [tex]\frac{1}{3}[/tex] , then
[tex]\sqrt[y]{3^{2} }[/tex] = [tex]\frac{1}{3}[/tex]
[tex]3^{\frac{2}{y} }[/tex] = [tex]3^{-1}[/tex]
Equating the exponents gives
[tex]\frac{2}{y}[/tex] = - 1 ⇒ - y = 2 ⇒ y = - 2

rectangular shape, and will be 8 m long and 3 m wide. She wants to
put a fence around the garden. On each corner a metal post must be
planted, and along the sides, a thin metal post (a “dropper") must be
inserted every metre. Two posts, similar to the corner posts, must be
planted 1 m apart along one length to allow for a gate. Two horizontal
steel wires will be stretched around the camp, except at the gate.
Chicken wire fencing is to be attached to these two wires.

ED = 32 ft
EC = 32 ft
DC = 28 ft
AC = 28 ft
BC = 32 ft
Answer:
AB = 32 ft
Step-by-step explanation:
If you rotate Triangle ECD 180 degrees clockwise, you will see that the sides line up perfectly with Triangle BCA, meaning that ED = AB and ED = 32 (transitive property of equality) so AB must also equal 32.

2x = 5x - 10 is equivalent to -3x = -10.
True or false
Answer:
True
Step-by-step explanation:
2x = 5x - 10
Subtract 5x from each side
2x-5x = 5x-10-5x
-3x = -10
Answer:
True
Step-by-step explanation:
Given
2x = 5x - 10 ( subtract 5x from both sides )
- 3x = - 10 ← equivalent → True

what is the equation of the line written in general form?
Answer:
option 2 or y + x -2 = 0
Step-by-step explanation:
Given a line on a graph, it is easiest to start with point-slope form.
y = mx + b
where m is the slope (rise/run) and b is the y-axis intercept.
From the plot m = -2/2 = -1 and b = 2 SO
y = mx + b
y = -x + 2
Then the general form is
y + x -2 = 0

I need help on #17 can someone please help me?
Answer:
t=2
Step-by-step explanation:
We are given the equation
h = -16t²+36t+1
Next, we are asked to find how long the ball was in the air (the time, in seconds) if Casey caught the ball 9 feet above the ground (9 feet is the height).
Therefore, as 9 is the height, we can plug that into our equation to get
9 = -16t²+36t+1
To make this a quadratic equation that is easy to factor, we can subtract 9 from both sides to get
-16t²+36t-8=0
To factor this, we need to find two values that add up to 36 and multiply to (-16)*(-8) = 128. With a little guess and check, I found the numbers 32 and 4 to work well. We can then make the equation
-16t²+32t+4t-8=0
-16t(t-2) + 4(t-2) = 0
(-16t+4)(t-2) = 0
Therefore, to solve for the equation being 0, or 9 = -16t²+36t+1, either (t-2) or (-16t+4) must equal 0
t-2 = 0
t=2
-16t+4 = 0
-16t = -4
t = 1/4
Therefore, t=1/4 and/or t=2. To figure out which one it is (or both!), we can take into account that the question states "on its way down". This means that the ball goes up and then down, and we want to find t when it is going down. Using the knowledge that a ball that is hit goes up and then down, as well as that -16t²+36t-8=0 is a quadratic equation with 2 solutions, we can say that the higher value of t (t=2) represents when the ball is going down

A desk drawer contains 5 red pens, 6 blue pens, 3 black pens, 24 silver paper clips, and 16 white paper clips. If you select a pen and
a paper clip at random, what is the probability that you select a black pen and a white paper clip? Round to the nearest tenth of a
percent
O A. 11.72%
B. 12.12%
C. 9.9%
O D. 8.6%
Answer:
Step-by-step explanation:
Probability of black pens = 3/14
Probability of white paper clips = 16/40
to find the probability of black pen and white paper clip we have to multiply these two probability.
3/14 x 16/40 = 48/560 = 8.6

Answer:
4050 cubic feet
Step-by-step explanation:
We would break this figure down into the square pyramid on the top and the cube on the bottom.
Volume of the cube:
l*w*h
= 15*15*15
= 3375.
Volume of the square pyramid:
a^2*(h/3)
= 15^2*(9/3)
= 225*3
= 675
Now we add the two to get the final answer:
3375+675=4050
The figure is 4050 cubic feet.
I hope this helped! :D
Answer:
Step-by-step explanation:
Cube:
Volume = length x width x height
V = 15 * 15 * 15
(Simplified version): 15³
V = 3,375ft³
Triangle:
Volume = 1/2 * base * height * length
V = 1/2 * 15 * 9 * 15
V = 1,012ft³
Add them both up to get our answer
3,375ft³ + 1,102ft³
4,477ft³
Therefore the volume of the figure is 4,477ft³
