Answer:
1/12
Step-by-step explanation:
The total number is 12 (assuming the dice would be rolled 12 times) 7 is a number in the range and it will appear once in the 12 rolls because each number shows each time. 1 (how many times 7 will show)/ 12(total number of rolls)
Probability of [tex]7[/tex] when a dice (showing numbers 1 throught 7) is thrown is equal to [tex]\boldsymbol{\frac{7}{12}}[/tex] as a dice is rolled.
Define probability.Probability refers to chances of occurrence of any event.
Value of probability lies in the interval [tex]\boldsymbol{\left [ 0,1 \right ]}[/tex]
Total number of numbers on a dice [tex]=12[/tex]
Probability is equal to number of favorable outcomes divided by the total number of outcomes.
Probability of [tex]7=\frac{7}{12}[/tex]

The area of a
circular fountain is
225πft2. What is the
diameter of the
fountain?
Using the formula for area of a circle: area = pi x r^2
You now have:
225pi ft^2 = pi x r^2
Divide both sides by pi:
225 = r^2
Take the square root of both sides:
r = 15
The radius is 15 feet.
The diameter is the radius x 2:
Diameter = 15 x 2 = 30 feet.
Answer: 30 feet.

Answer:
[tex]\Huge\boxed{x=11.8}[/tex]
Step-by-step explanation:
Hello There
cos = adjacent divided by hypotenuse
the adjacent side of the angle that has a measure of 49 is x and the hypotenuse is 18
so
[tex]cos49=\frac{x}{18}[/tex]
once again we want to isolate the variable using inverse operations
to get rid of the 18 we multiply each side by 18
[tex]\frac{x}{18} *=x\\cos49*18=18cos49[/tex]
we're left with
[tex]x=18cos49[/tex]
now we let the calculator do the rest of the work
we end up with
[tex]x=11.80906252[/tex]
our final step would be to round to the nearest tenth
so we can conclude that the x = 11.8

Step-by-step explanation:
There are about 52.14 weeks in a year. If you multiply 40 by 52.14 you get 2085.6. Then you divide 75,400 by 2085.6 and that's how I got my answer. If I'm wrong, someone feel free to correct me.

I really need help with this!!
Answer:
x = 4
y = 3.5
Step-by-step explanation:
The parallelogram given has opposite sides that are equal in length. Therefore, the diagonals bisect each other into two equal parts respectively.
Thus:
2y = 7
Divide both sides by 2
y = 7/2
y = 3.5
Also,
x + 6 = 10
Subtract 6 from each side
x = 10 - 6
x = 4

Answer:
160 acres
Step-by-step explanation:
Given data
Total Amount of land= 280 Acres
Ratio=4:3
Total part = 4+3= 7
Applying the part to all method
let AI receive x acres
Then
4/7= x/280

Find the measure of angle x?
Answer:
x = 43 degrees
Step-by-step explanation:
First, you have to see that there is a right angle of 90 degrees. Since that is there, you know that there is 90 degrees in the bottom and right side as well. So all you do in this question is do 90 - 47 to get your answer of 43 degrees.

What is the first step Anika made from the original equation.
Answer:
She factored out a 4 from the equation.
Step-by-step explanation:
So our original equation is 12x + 4 = 20x - 12
Anika's first steep of her equation is 3x + 1 = 5x - 3
We know that the terms were not moved around, so the first step was likely multiplication or division.
We also see that a 4 has been factored out of the entire equation, like this:
12x + 4 = 20x - 12
4(3x + 4) = 4(5x - 3)
And these 4's cancel each other out.
So, I conclude that Anika's first step was dividing the entire equation by 4 or factoring out a 4 from the equation.

Explanation for last two:

Step 1: Subtract 5 from both sides.
[tex]\frac{-2}{7} t+5-5=17-5[/tex]
[tex]\frac{-2}{7} t=12[/tex]
Step 2: Multiply both sides by 7/(-2).

t=−42
4.9x+4.2=9.1
