Step-by-step explanation:
A spinner has 20 total spaces that are either blue or red. The spinner is spun, and a die is rolled. If the probability of landing on a blue space AND a 3 is 10.83%, how many blue spaces are there on the spinner?
Answer:
Step-by-step explanation:
Remark
We have to assume that the die is a cube.
We know that getting a 3, if the die is fair, is 1 chance out of 6 = 1/6
We don't know how many blues there are on the spinner, but we do know that the number of them is over 20. So that's x/20
Now multiply the left side to get the combined probability. x/20 * 1/6. The result is 10.83/ 100
Solution
(x/20) * (1/6) = 10.83/100
x / 120 = 10.83/100 Multiply both sides by 120
x = 10.83 * 120 / 100
x = 12.996 which is going to round to 13
The blue spaces = 13

Answer:
1)x=-6,y=1 2)a=0,b=-8 3)j=8,k=1 4)m=3,n=-6
Step-by-step explanation:
1)x-4y=-10,2x+y=-11
x-4y=-10
x=4y-10
2\left(4y-10\right)+y=-11
8y-20+y=-11
9y-20=-11
9y=9
y=1
x=4-10
x=-6
x=-6,y=1
2)a-3b=24,a+2b=-16
a-3b=24
a=3b+24
3b+24+2b=-16
5b+24=-16
5b=-40
b=-8
a=3\left(-8\right)+24
a=-24+24
a=0
a=0,b=-8
3)k-j=-7
4j-5k=27,-j+k=-7
4j-5k=27
4j=5k+27
j=\frac{1}{4}\left(5k+27\right)
j=\frac{5}{4}k+\frac{27}{4}
-\left(\frac{5}{4}k+\frac{27}{4}\right)+k=-7
-\frac{1}{4}k-\frac{27}{4}=-7
-\frac{1}{4}k=-\frac{1}{4}
k=1
j=\frac{5+27}{4}
j=8
j=8,k=1
4)m+n=-3,m-4n=27
m+n=-3
m=-n-3
-n-3-4n=27
-5n=30
n=-6
m=-\left(-6\right)-3
m=6-3
m=3
m=3,n=-6

Help!!! Please!!! The linear regression for this print-out relates the amount of oxygen in your spaceship measured in liters as a function of time In hours
Interpret the meaning of the slope in the context of the problem
Answer:
Please check explanations
Step-by-step explanation:
When we talk about the slope, we are simply referring to the change in y-value with respect to a change in x-value
From the regression line equation, we can see that the value of the slope is negative
What this means is that as the x value is increasing, the y value is decreasing
This makes sense in the context of the problem because it is expected that the amount of fuel in liters is expected to decrease with an increasing amount of time
Solve for x.

A. 39.3
B. 34.5
C. 37.8
D. 35.9
Answer:
[tex]\mathrm{A.\: 39.3}[/tex]
Step-by-step explanation:
Let [tex]h[/tex] represent the height of the two smaller triangles in this figure. Because all three triangles are similar, we can set up the following proportion:
[tex]\frac{33}{h}=\frac{h}{y}[/tex], for [tex]y=x-33[/tex].
We can solve for [tex]h[/tex] using the Pythagorean theorem on the second largest triangle:
[tex]33^2+h^2=36^2,\\h=\sqrt{36^2-33^2},\\h=\sqrt{207}[/tex].
Now plugging in [tex]h=\sqrt{207}[/tex] into our proportion [tex]\frac{33}{h}=\frac{h}{y}[/tex], we can solve for y:[tex]\frac{33}{\sqrt{207}}=\frac{\sqrt{207}}{y}[/tex].
Cross-multiply to get:
[tex]33y=207,\\y=\frac{207}{33},\\y\approx 6.3[/tex].
Since we [tex]y=x-33, y+33=x[/tex].
Therefore, our answer is:
[tex]x=33+y=33+6.3=\fbox{$\mathrm{A.\: 39.3}$}[/tex].

Step-by-step explanation:
a wave has wavelength of 10m and a speed of 340m/s.what is frequency of the wave
340=10f.
frequency=34hertz.
Step-by-step explanation:
We have the wavelength which is 10,speed/velocity=340 and frequency=?.
The formula is velocity=frequency × wavelength.
340=f × 10.
340=10f.
frequency=34hertz.

My question is regarding cylinders plz.. Here it goes - a student winds a strip of paper eight times round a cylindrical pencil of diameter 7mm. Use the value 22/7 for π to find the length of the paper (ignore the thickness of the paper) pls I don't understand this .. Pls help
Answer:
176cm
Step-by-step explanation:
Step 1
We find the circumference of the cylinder
The formula for the Circumference = 2πr or πD
π = 22/7
Hence;
22/7 × 7
= 22
Since the strip of paper eight times round a cylindrical pencil of diameter 7mm, the length of the paper is calculated as: 22 × 8
= 176cm

At present a women is twice as old as her daughter . Twenty one years ago she was three times older than her daughter . What is the women's present age?
Answer:
84 years
Step-by-step explanation:
Given :
At present :
Let :
daughter's age = x
Woman's age = 2x
21 years ago :
Woman's age = 3 times daughter's age
2x - 21 = 3(x - 21)
2x - 21 = 3x - 63
-21 + 63 = 3x - 2x
42 = x
Daughter's age = 42
Woman's age = 2x = 84
Hence, woman's present age is 42 years
Betty correctly determined that the ordered pair (-3,5) is a solution to the system of linear equations 6x+5y = 7 and x + 4y = = 17. Based on this information, which statement is correct? O(-3,5) satisfies neither the equation 6x + 5y = 7 nor the equation x + 4y = 17. O(-3,5) satisfies the equation 6x + 5y = 7 but not the equation x + 4y = 17. O (-3,5) satisfies the equation x + 4y = 17 but not the equation 6x + 5y = 7. O(-3,5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.
Answer:
(-3, 5) satisfies both the equation 6x + 5y = 7 and the equation x + 4y = 17.

A math test has 25 problems on it. If a student incorrectly answers 5 problems on the test,
what percentage of problems are correct? Be careful, reread the question.
(1 Point)
Answer:
i beleve they would get an 80% sorry if im wrong
Answer:
the answer is 80%
Step-by-step explanation:
Think of it this way
There is 5 problems wrong out of 25 so 5/25 is the fraction (right/ number of questions)
5/25 can be simplified to 1/5 (divide by 5)
1/5 can be transformed to the percentage 20%
NOW BE CAREFUL 20% is what is WRONG so 100-20=80
so 80% is thus the answer
Enjoy :)
