There are 18 marbles in Molly's bag. Two of the marbles are yellow. If Molly chooses one marble at random, find the theoretical probability that she will choose a yellow marble.
Answer:
1/9
Step-by-step explanation:
To find this probability, we simply divide the number of yellow marbles by the total number of marbles
From the question, there are a total of 18 marbles and 2 yellow ones
thus, the theoretical probability of selecting a yellow marble will be;
2/18 = 1/9
The cost of one CD and one DVD is $22. A DVD is $4 more expensive than a CD. Work out the individual prices of 1 CD and 1 DVD.
Answer:
ets Price of a DVD is fixed i.e. 15
and One CD price is 5 (Not fixed)
In First situation
2 DVDs and 1 CD cost = 35 as given
2 x 15 + 5 = 35
Lets one CD price is 7.5
In Second situation
2 x 15 + 2 x 7.5 = 45
Its mean CD price may be between 5 to 7.5
In asked scenario, Martin has 50
1 DVD and 3 CDs?
1 x 15 + 3 x 7.5 = 37.5
37.5 is lesser than 50
Step-by-step explanation:
Answer:
CD = $9
DVD = $13
Step-by-step explanation:
CD+DVD = 22
DVD = CD+4
substitute for DVD
CD +(CD+4) = 22
2CD+4 = 22
2CD = 18
CD = 9
DVD = 13

I’m a bit confused on how to solve this problem, and could use some help!
Answer:
Okay to start with we know this side isn't congruent to our side with 55 degrees looking at this side we can see that x is not 95 degrees because it is an acute angle so A is crossed out. Next this side isn't congruent like I said so B is crossed out. C is possible but the angle wouldn't be as wide as it is if we had 59 degrees so C is incorrect. Leaving us with D 70 degrees hope this helps and sorry if I got it wrong!

Answer:
C. x = 6
Step-by-step explanation:
Answer: 6
Step-by-step explanation:
Solve for X
7 + 5 ( x - 3 ) = 22
7 + 5x - 15 = 22
-8 + 5x = 22
5x = 30
x = 6
Now check your work
7 + 5 ( 6 - 3 ) = 22
7 + 5 ( 3 ) = 22
7 + 15 = 22
22 = 22

The quantities x and y are proportional. Use each of the integers 1-5 to complete the table. **CORRECT ANSWER IS GIVEN BRAINLEST POINTS**
Answer:
x 10 4 6 1
y 5 2 3 0.5
Step-by-step explanation:
You have to start with a guess and see if it works. If it works, you're done. If it doesn't work, you need to make a difference guess.
I'll start by guessing that above the 0.5 is a 1.
If that is correct, then every x value is double the y value below it.
5 goes below the 10. 3 goes below the 6. Then you have 4 and 2 left.
That is every whole number from 1 to 5. It works.
x 10 4 6 1
y 5 2 3 0.5

if fred can blow up 20 balloons up in 15 minutes then how many balloons can fred blow up in 6 minutes
Answer:
8
Step-by-step explanation:
have a good day
Answer:
The Answer is 8
Step-by-step explanation:
Hello,
The answer to the question is 8, let me explain why.
1. we know how many balloons Fred can blow up in 15 minutes
Fred can blow up 20 balloons in 15 minutes.
2. we need to find out how many balloons Fred can blow up in 1 minute.
To solve this we just divide 20 by 15
20 ÷ 15 = 1.3 (repeated)
3. Finally we multiply the answer by 6
This will give us the answer of 8
because 1.3 × 6 = 8
Hope I could help, Hope it was easy to understand as well.

Subtract 17x2y2z−14xyz from −18x2y2z+4xyz
Answer:
The difference is;
-35x^2yz^2 + 18xyz
Step-by-step explanation:
Here, we want to have a subtraction
we have this as;
(-18x^2y^2z + 4xyz) - (17x^2y^2z - 14xyz)
= -18x^2y^2z -17x^2y^2z + 4xyz + 14xyz
= -35x^2yz^2 + 18xyz

i need help please, ill give a brainlist to the best answer.
Step-by-step explanation:
y = 6x - 24
y = -2x
=> 6x - 24 = -2x [We change the two sides of y = two equations x above]
=> 6x - 24 + 2x = 0
=> 8x = 24
=> x = 3
=> y = -2 x 3 = -6
=> The correct ans will be (3 , -6) [x is always placed before y]
The wheels on Darlene's car have on 11-inch radius. If the wheels are rotating at a rate of 378 rpm, find the linear speed in miles per hour in which she is traveling.
Answer:
The linear speed in which Darlene is traveling is 24.74 miles per hour.
Step-by-step explanation:
The wheel experiments rolling, which is a combination of translation and rotation. The point where linear speed happens is located at geometrical center of the wheel and instantaneous center of rotation is located at the point of contact between wheel and ground. The linear speed ([tex]v[/tex]), measured in inches per second, is defined by following expression:
[tex]v = R\cdot \omega[/tex] (1)
Where:
[tex]R[/tex] - Radius of the wheel, measured in inches.
[tex]\omega[/tex] - Angular speed, measured in radians per second.
If we know that [tex]R = 11\,in[/tex] and [tex]\omega \approx 39.584\,\frac{rad}{s}[/tex], then the linear speed, measured in miles per hour, in which Darlene is traveling is:
[tex]v = 11\,in\times \frac{1\,mi}{63360\,in} \times 39.584\,\frac{rad}{s}\times \frac{3600\,s}{h}[/tex]
[tex]v \approx 24.74\,\frac{mi}{h}[/tex]
The linear speed in which Darlene is traveling is 24.74 miles per hour.

90y + 65z = ??
using gcf
Answer: the gcf is 5
Step-by-step explanation:
The Greatest Common Factor for the equation 90y + 65z is 5.
What is Greatest Common Factor?The largest number among all the common factors of the given numbers is known as the GCF (Greatest Common Factor) of two or more numbers. The greatest integer that may be used to divide two natural numbers x and y without producing any remainder is called their GCF.
Given the equation 90y + 65z
where y and z are variables,
to find the GCF of the equation,
factors of 90 are 2 x 3 x 3 x 5
factors of 65 are 5 x 13
substitute the value of 90 and 65
equation is 2 x 3 x 3 x 5y + 5 x 13z
5(18y + 13z)
Hence GCF of the equation is 5.
