Answer:
The area of this circle is 78.5
Step-by-step explanation:
The area of a circle can be calculated with the equation πr². r stands for "radius", the distance between the center of the circle to any point of its edge which also equals to half of a circles diameter. Since the diameter of this circle is 10 in., its radius is
[tex]r = d/2 = 10/2 = 5\\[/tex]
Then, we use this to find the area
Area =[tex]\pi r^2=\pi (5)^2=25\pi=78.5[/tex] (rounded to the first decimal place)

The angles of a quadrilateral are in the ratio 2:4:5:6 what is the difference between the largest angle and the smallest angle
Answers
Answer:
85
Step-by-step explanation:
From the question given above, the following data were obtained:
Ratios of the angle => 2 : 4 : 5 : 6
Difference between the largest angle and the smallest angle =?
Next, we shall determine the various angles in the quadrilateral. This can be obtained as follow:
Ratios of the angle => 2 : 4 : 5 : 6
Total ratio = 2 + 4 + 5 + 6
Total ratio = 17
Angle in a quadrilateral = 360
For ratio 2:
Angle = 2/17 × 360 ≈ 42
For ratio 4:
Angle = 4/17 × 360 ≈ 85
For ratio 5:
Angle = 5/17 × 360 ≈ 106
For ratio 6:
Angle = 6/17 × 360 ≈ 127
SUMMARY:
The angles are => 42°, 85°, 106° and 127°
Finally, we shall determine the difference between largest angle and the smallest angle. This can be obtained as follow:
Smallest angle = 42°
Largest angle = 127°
Difference between the largest angle and the smallest angle =?
Difference = Largest – Smallest
Difference = 127 – 42
Difference = 85
Thus, the difference between the largest angle and the smallest angle is 85.
How much charge is needed to repel another charge of 9.9 x 10^-6 N when they are 200m apart? Please help meee I really can't understand Coulomb's Law : (
Answers
Answer:
The charge needed will be [tex]q=6.6\: \mu C[/tex]
Step-by-step explanation:
The equation of the electric force is given by:
[tex]F=k\frac{qQ}{r^{2}}[/tex]
We have the force [tex]F = 9.9 10^{-6}\: N[/tex] and the distance r = 200. k is the Coulomb constant. Q and q are the charges.
We assume we have the same charge of the particles, so we have:
[tex]q^{2}=\frac{Fr^{2}}{k}[/tex]
[tex]q^{2}=\frac{9.9*10^{-6}200^{2}}{9*10^{9}}[/tex]
[tex]q=6.6*10^{-6}\: C[/tex]
Therefore, the charge needed will be [tex]q=6.6\: \mu C[/tex]

if the price of aluminum cans is 32 cents per pound and it takes 32 cans to make 1 pound how many cans do I need to make $100?
Answers
Answer:
1,000 cans
Step-by-step explanation:
Since there are 32 cans per pound and each pound is 32 cents. You divide 32/32 which tells you each can is 1 cent. So 100 dollars divided by 1 cent is 1,000 cents or 1,000 cans since each can is 1 cent.
Answer:
1000 can

In continuous type of series, for finding mean, which amongst the
following is considered as X variable value?
Select one:
O a lower limit of the interval
O b. upper limit of the interval
O c. mid point of the interval
O d. none of these
Answers
In the continuous type of series for determining the mean, the midpoint of the interval should be considered as the X variable value.
Continuous Series is the series where all types of class intervals with the frequency should be listed in the table form. Here all the class intervals do not contain a similar frequency.
For determining the mean, the direct method should be used in which the midpoint from X should be measured and the same should be relevant.
So, the following should not be relevant for determining the mean:
The lower limit and upper limit of the interval.Therefore In the continuous type of series for determining the mean, the midpoint of the interval should be considered as X variable value.

Mia's distance to the river is decreasing in the interval 0 < t < 1.25
Mia drives 100 miles to the beach.
Step-by-step explanation:
A line that slopes down to the right is decreasing. It has negative slope.
A line that slopes up to the right is increasing. It has positive slope.
The graph slopes down to the right from time = 0 to time = 1.25 hours.
Mia's distance to the river is decreasing in the interval 0 < t < 1.25 .
On the top left of the graph, at time = 0, the distance to the river is 50 miles. Her house is 50 miles from the river. After the river, she drives another 50 miles to get to the beach. You see that at point (2.5, 50). Two-and-a-half hours after she leaves home, she is 50 miles away from the river after having driven a total of 100 miles.
Mia drives 100 miles to the beach.

Step-by-step explanation:
In triangle UTR, measures of all angles are equal (60°). (given)
Therefore, it is an equilateral triangle.
So, it's sides will also be equal.
In triangle TRS, m angle T = m angle S
So, RT = RS = 11 (sides opposite to the equal angles are equal)
In triangle URT,
UT = RT (sides of equilateral triangle)
x - 7 = 11
x = 11 + 7
x = 18
In triangle TRS,
m angle T = m angle S = 5y°
m angle R = 180° - 60° = 120° (Linear pair angles)
5y° + 5y° + 120° = 180°
10y° = 180° - 120°
10y° = 60°
y = 60/10
y = 6
