Calcular el área y el perímetro de un círculo que tiene 50 cm de radio
Answers
Answer:
Area: 7850 square cm
Perimeter: 314 cm.
Step-by-step explanation:
The area is [tex]\pi r^{2}[/tex]. With r=50, [tex]\pi 50^{2}[/tex]=2500π which is about (2500)(3.14)=7850.
The perimeter is [tex]2\pi r[/tex] which is the same as (diameter)(π). The diameter is 100, so [tex]100\pi[/tex] which is about (100)(3.14)=314.

Answers
Answer:
$66.80
Step-by-step explanation:
multiply 5.85 by 8 and then add the product to 20 to get the total
After the eight weeks, Rita has $66.8 now.
What is multiplication?Multiplication is a mathematical arithmetic operation. It is also a process of adding the same types of expression for some number of times.
Example - 2 × 3 means 2 is added three times, or 3 is added 2 times.
Given, Rita had $20.
Then she saved $5.85 each week for 8 weeks
That means,
she saved the amount,
= amount saved in one week multiplied by 8
She saved the amount
= $5.85 x 8
$5.85 × 8 means $5.85 is added eight times.
Rita saved the amount
= $5.85 x 8
= $46.8
To find the total amount;
$20 + $46.8 = $66.8
And bar diagram is in the attached image.
Therefore, she has $66.8.

14V + 5 − 5V = 4(V + 15)
Answers
Answer:
V=11
Step-by-step explanation:
Simplify:
14V-5V+5=4V+60
9V+5=4V+60
Subtract 4V on both sides:
9V-4V+5=4V-4V+60
Solve:
5V+5=60
Subtract 5 on both sides:
5V+5-5=60-5
5V=55
Divide by 5
V=11
Hope this helps!
Step-by-step explanation:
14V+ 5 - 5V= 4V+ 60|-60|-4V
14V + 5 -5 V - 60 - 4V =0
<=> 5V - 55 =0 |+55

∠1≅∠7
∠1≅∠3
∠3≅∠7
Answers
Answer:
Option (3)
Step-by-step explanation:
There are two parallel lines 'p' and 'q' and a transversal line is intersecting these lines at two distinct points.
Each pair of angles formed on the inner side of the parallel lines but opposite sides of the transversal line are the alternate interior angles.
Pair of angles (∠2 and ∠6) and (∠3 and ∠7) are the alternate interior angles.
Since, alternate interior angles are equal in measure,
∠2 ≅ ∠6
∠3 ≅ ∠7

Step-by-step explanation:
Answer:
[tex]3\frac{1}{5}[/tex]
Step-by-step explanation:
First you want to find the least common denominator so we can figure out this problem.
We have [tex]3\frac{3}{10} , 6\frac{1}{2}[/tex] so all we need to do is multiply ONLY the fraction next to the 6 so we can figure out what 1/2 and 3/10 correlates to which you will get
By multiplying by 5 you can get the same equation so the common denominator relates to one another.You get 5 by doing 10/2 which is 5.so your new question is
[tex]3\frac{3}{10} , 6\frac{5}{10}[/tex]
Which is so much easier, all you need to do is subtraction between the two!
5/10-3/10 is 2/10
2/10=1/5
Then we got the whole numbers
6-3=3
so the answer is [tex]3\frac{1}{5}[/tex]

Answers
Answer:
4x - 6
Step-by-step explanation:
Matt: x
Steve: 2(x - 2)
John: x - 2
Total magazines sold:
x + 2(x - 2) + (x - 2)
x + 2x - 4 + x - 2
4x - 6
The simplified expression representing the total amount of magazines sold is 4x - 6
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
A mathematical equation is a statement with two equal sides and an equal sign in between. An equation is, for instance, 4 + 6 = 10. Both 4 + 6 and 10 can be seen on the left and right sides of the equal sign, respectively.
We are given that Matt, Steve and John sold magazines for a school fundraiser. John sold two less than Matt. Steve sold twice as many as John.
Let the variable Matt: x
Steve: 2(x - 2)
John: x - 2
Now Total magazines sold:
x + 2(x - 2) + (x - 2)
Solving;
x + 2x - 4 + x - 2

> Question A normal distribution is observed from the number of points per game for a certain basketball player. If the mean is 15 points and the standard deviation is 3 points, what is the probability that in a randomly selected game, the player scored greater than 24 points?
Answers
Answer:
The probability that in a randomly selected game, the player scored greater than 24 points is 0.0013 or 0.13%
Step-by-step explanation:
Given that
Mean = μ = 15 points
SD = σ = 3 points
For calculating probability for a data point, first of all we have to calculate the z-score of the value.
We have to find the probability of score greater than 24, then the z-score of 24 is:
z-score = (x-μ)/σ
z = (24-15)/3
z = 9/3
z = 3
Now we have to use the z-score table to find the probability of z<3 then it will be subtracted from 1 to find the probability of z>3
So,
[tex]P(z<3) = 0.9987\\P(z>3) = 1 - P(z<3) = 1-0.9987 = 0.0013[/tex]
Converting into percentage
0.0013 * 100 = 0.13%
Hence,
The probability that in a randomly selected game, the player scored greater than 24 points is 0.0013 or 0.13%
Answer:0.15%
Step-by-step explanation:
Notice that 24 points is three standard deviations greater than the mean. Based on the Empirical Rule, 99.7% of the player's game scores are within three standard deviations of the mean. Since the normal distribution is symmetric, this implies that 0.15% of the player's game scores are greater than three standard deviation more than the mean.
