4·π·82≈50.26548cm²
Answer:
16π cm^2
Step-by-step explanation:
The formula for the area of a circle is [tex]\pi r^{2}[/tex], r being the radius. The radius is always half of the diameter, so in this case, the radius is 4. [tex]4^{2}[/tex] is just 4 * 4 which is 16. Multiply that by π and you get 16π. Or, approximately 50.27 cm^2

kali runs 12 laps around a track each day. Each lap around the track is 400 meters. How many days will it take Kali to run the total of 12 kilometers?
Answers
Answer: 2.5 days
Step-by-step explanation:
First we should convert 12 kilometers to meters so that is 12000 meter. Now we know that she runs 12 laps each day and each lap is 400 meters so lets find out how much she runs in one day. 12 laps*400meters= 4800 meters
So an easy way to figure out how many days is to divide 4800 meters she runs each day from the total 12,000 meters she needs to run so 12,000/400=2.5.
It will take kali a total of 2.5 ( two and a half days) to run 12000 meters or 12 kilometers

Find the measure of the indicated angle to the nearest degree
Answers
Answer:
32°
Step-by-step explanation:
use this formula :
Now you want to get the angle be x, so the opposite side is 28 and hypotenuse is 53. Putting in the formula we get:
Sin(x) = 28/53
Sin(x)= 0.5283018868
So to find x just do Sin^-1
x = Sin^-1 (0.5283018868)
you get 31.8907918, ok so we just want the nearest degree and if we do that we get 32˚
if you put them into your calculator you will get 32˚ as your answer

The perimeter of an equilateral triangle is 11 inches more than the perimeter of a square, and the side of the triangle is 6 inches longer than the side of the square. find the side of the triangle.
Answers
Answer:
13 inches
Step-by-step explanation:
Let P(t) and P(s) be the perimeters of the equilateral triangle and square respectively. Similarly, t and s be the side lengths of equilateral triangle and square respectively.
According to the first condition :
(Perimeter of an equilateral triangle is 11 inches more than the perimeter of a square)
[tex] \implies P(t) = P(s) + 11[/tex]
[tex] \implies 3t = 4s + 11....(1)[/tex]
According to the second condition :
(The side of the triangle is 6 inches longer than the side of the square)
[tex] \implies t = s + 6....(2)[/tex]
From equations (1) & (2)
3(s + 6) = 4s + 11
3s + 18 = 4s + 11
3s - 4s = 11 - 18
-s = - 7
s = 7 inches
[tex] \because t = s + 6[/tex]
[tex] \because t = 7 + 6[/tex]
[tex] \because t = 13\: inches[/tex]
Thus the side of the triangle is 13 inches long.

Convert: a) 8250 g =________________kg b) 10 3/4 l =______________ ml c) 6 m 5 cm =_____________ cm d) 9 km 50 m =____________m *
Answers
Answer:
See answers below
Step-by-step explanation:
Convert: a) 8250 g =________________kg b) 10 3/4 l =______________ ml c) 6 m 5 cm =_____________ cm d) 9 km 50 m =____________m *
a) Note that 1000g = 1kg
8250g = x
1000 * x = 8250
1000x = 8250
x = 8250/1000
x = 8.25kg
b) 10 3/4 l to ml
1l = 0.001ml
10 3/4 l = x
Cross multiply
1 * x = 10 3/4 * 0.001
x = 43/4 * 0.001
x = 0.043/4
x = 0.01075ml
c) 6m 5cm to cm
Since 1m = 100cm
6m 5cm
= 6(100) + 5
= 600 + 5
= 605cm
d) 600km 50m to m
1000m = 1km
x = 9km
x = 9000m
600kn 50m
= 9000m + 50m
= 9050m

A rectangle has vertices located at (–4, 4), (2, 4), (2, –4) and (–4, –4). What is the length of a diagonal of the rectangle?
Answers
Answer:
A diagonal of this rectangle has length 10.
Step-by-step explanation:
The vertices (-4, 4) and (-4, -4) have the same x-coordinate (-4) and different y-coordinates (4 and -4). These two points are the endpoints of a vertical side of the rectangle which has length 4 - (-4) = 8.
Similarly, the vertices (2, -4) and (-4, -4) have the same y-coordinate (-4) but different x-coordinates (2 and -4). To find the horizontal dimension of the rectangle, we calculate 2 - (-4), which comes out to 6.
Thus, the width of the rectangle is 6 and the length is 8.
Using the Pythagorean Theorem, we find the length of a diagonal as follows:
d = √(6^2 + 8^2) = √(36 + 64) = √100 = 10.
A diagonal of this rectangle has length 10.

Answers
Answer: 81.2
Step-by-step explanation:
h(t) = -5t² + 40t + 1.2
h(4) = -5(4)² + 40(4) + 1.2 We plug 4 seconds as t, and solve h(4)
h(4) = -80 + 160 + 1.2
h(4) = 80 + 1.2
h(4) = 81.2

MABC = [ ? 1°
Answers
Answer:
i get mABC = 270°
Step-by-step explanation:
This is fairly straight forward once you the right angle symbol for the arc AC. Also realizing the 148° for mAB is not needed for this question. The 148° for mAB would be useful if you wanted to calculate arc mBC.
Remember there are 360° in a circle.
The arc mAC is 90°
The arc mABC is the rest of the circle. is the arc from A to B to C
arc ABC + arc AC is the full circle 360°
mABC + mAC = 360° mAC = 90°
mABC + 90° = 360° - 90° from both sides
mABC = 360° - 90°
mABC = 270°
The angle ∠ABC in the given circle will be 270°.
What is an angle?
An angle is a geometry in plane geometry that is created by 2 rays or lines that have an identical terminus.
Angle is very useful to measure any angular rotational motion for example if you have to find out the rotation among the circle then it cannot measure in length parameter such that meter inch so it will be measured as an angle in a unit of degree or radian.
In another word, the angle is the measurement of the angular distance for example for linear motion we have a meter inch but for angular rotation, we don't have the measurement so the angle is useful to measure the angular rotation.
Now since we know that the angle of complete rotation is 360°.
Now ∠ADC + ∠ABC = 360
Given that ∠ADC = 90°
∠ABC = 360° - 90° = 270°
Hence, 270° will be the correct answer.

What is P(not prime)?
Write your answer as a percentage.
Answers
==========================================================
Explanation:
The primes in this list are: {2,3,5}
The value 1 is not prime.
We have 3 primes out of 5 values total, so 3/5 = 0.6 = 60% of the list is prime. That makes 100% - 60% = 40% of values are not prime
This is the probability of getting a non-prime number.
Answer:
40%
Step-by-step explanation:
Prime numbers are whole numbers greater than 1 that only have 2 factors, for example, 2, 3, 5, 7, 11 are all prime numbers
In this data set 2, 3, and 5 are all prime numbers
3 out 5 numbers are prime
so the fraction is [tex]\frac{3}{5}[/tex]
after you have found the fraction, you can divide it to find the percentage
In this case, when you divide the fraction you get 0.6
to make this a percentage you move the decimal place two spaces to the right. so 60%
60% are the values that are prime so you do this equation
100%-60%=40%
