Answer:
Arc length, S...is given by
S = r (theta in radians)
So
S = 28 (3π/4) = 28 (3/4)*π = [ 21 π ] inches
Step-by-step explanation:
The length of the arc intercepted by a central angle that measures 3π/4 radians will be 113.04 millimeters.
What is Circle?The circle is a closed two dimensional figure , in which the set of all points is equidistance from the center.
Given that;
The central angle = 3π/4
And, A circle has a radius of 48 millimeters.
Now,
We know that in circle;
Arc = Radius × Angle
Substitute all the values, we get;
⇒ Arc = 48 × 3π/4
⇒ Arc = 3 × 12 × 3.14
⇒ Arc = 113.04 millimeters
Thus, The length of the arc will be;
Arc = 113.04 millimeters

In 45 years will be 4 times older how old is she now
Answer and Step-by-step explanation:
The key for this has a current age and a future age. Sometimes these problems have more than one person or has a past age.
current age future age
x x+45
The future age is 4 times current age
x+45 = 4x
45 = 3x
15 = x
She is currently 15. 45 years from now she will be 60.
60 is 4 times her current age. So right now, she is 15.

A line through the origin and (10,4) is showin in the standard (x,y) coordinate plane below. The acute angle between the line and the positive x-axis has measure θ.
Answer:
[tex]\cos\theta=\frac{10}{\sqrt{116}}[/tex]
Step-by-step explanation:
To solve this, we can imagine a line drawn directly down from the point (10,4) to the x-axis. This would make a right triangle with length 10 and height 4.
[tex]\cos\theta[/tex] is equal to the length of adjacent leg to the angle divided by the length of the hypotenuse of the triangle. From the picture, we can see the adjacent leg is 10.
We can use Pythagorean's Theorem to find the hypotenuse (let [tex]c[/tex] represent the length of the hypotenuse):
[tex]10^2+4^2=c^2[/tex]
[tex]100+16=c^2[/tex]
[tex]116=c^2[/tex]
[tex]c=\sqrt{116}[/tex]
Thus, we know the adjacent is 10, and the hypotenuse is [tex]\sqrt{116}[/tex]. This means [tex]\cos\theta=\frac{10}{\sqrt{116}}[/tex].
Hope this helps!

You randomly choose a tile. Without replacing the first tile, you choose a second tile. Find the probability of the compound event. Write your answer as a fraction or percent rounded to the nearest tenth.The probability of choosing an odd number and then a 20
Answer:
P odd number, then 20) = 1 /14
Step-by-step explanation:
P( odd number) = number of odd numbers/ total
number of odd numbers = 3
total = 7
P( odd number) = 3/7
We keep the tile so that there are only 6 tiles left
P (20) = number of 20/ total
= 1/6
We multiply the probabilities together
P odd number, then 20) = 3/7 * 1/6 = 3/42 = 1 /14

The formula P=a+b+c gives perimeter P of triangle side lengths a,b,and c how much greater is perimeter when triangle measures 33yds 56yds and 65yds to a triangle that measures 26yds 49yds and 38yds
Answer:
41 yards greater is the perimeter of 1st triangular field than the perimeter of 2nd triangular field.
First we have to calculate the perimeter of 1st triangle.
Given:
a = 33 yards
b = 56 yards
c = 65 yards
Now we have to calculate the perimeter of 2nd triangle.
Given:
a = 26 yards
b = 49 yards
c = 38 yards
Now we have to calculate which triangle has greater perimeter and how much greater.
Therefore, 41 yards greater is the perimeter of 1st triangular field than the perimeter of 2nd triangular field.
Step-by-step explanation:
(154-113)
41 yards bigger
Answer:
41 yds
Step-by-step explanation:
33+56+65=154
26+49+38=113
154-113=41 yds
If the cost of electricity increases by 30% by what percentage one should reduce his spend in order that spends on electricity stays the same?
Answer:
That depend on how much you spend on electricity, and how much other spending you do.
For example: If your electric bill is 100 dollars, and it increases 30 percent to 130, that’s 30 extra dollars. If your electric bill is only 50 dollars, it will increase to 65, that’s an extra 15.
What percentage that increase is of your current spending will vary according to how much you spend. If you only spend 30 dollars, then you’ll need to cut all of it, or half of it to offset the increases I mentioned above. That’s a 100 percent or 50 percent reduction.
If you spend 1000 dollars, you’ll only need to cut spending by 3 percent to get that 30 dollars, or 1.5 percent to get the 15 dollars.
It all depends on your specific values, you can’t say “For every xx percent your electric bill increases, you need to cut spending by yy percent.”
for the consumption of X unit let u spends Y
for X - Y cost
for increased 30% means 13X/10 - 13Y/10 cost
extra money is 13Y/10 - Y = 3Y/10
note: hope this helps :)
thus (3Y/10)/ (13Y/10) *100 % = 300 / 13 = 23.07%.

Hence: 3.14 × (5)^2 × 15V= 1178.1Mia has 4 horses and 11 apples. She gives each horse the same number of
apples, and she uses as many apples as she can. How many apples does Mia
give each horse? How many apples are left?
» Complete the equation.
11 : 4 =
R
Answer:
She gives 2 apples to each horse, and there will be 3 apples left.
Step-by-step explanation:
We know that Mia has 4 horses and 11 apples
She gives each horse the same number of apples, such that she uses the maximum number of apples that she can.
If she has 4 horses and she gives the same amount to each horse (let's say that this amount is N apples to each horse)
Then she uses a total of 4*N apples.
Then if N = 1, she needs 4*1 = 4 apples.
if N = 2, she needs 4*2 = 8 apples.
if N = 3, she needs 4*3 = 12 apples.
But she has only 11 apples, so she can not give 3 apples to each horse.
Then the maximum number of apples that she can give to each horse is N = 2, 2 apples to each horse.
Now, we know that she has 11 apples in total, and she gives 2 to each of the 4 horses, then she gives:
4*2 = 8 apples.
The number of apples that are left are:
11 - 8 = 3
There are 3 apples left.
Find the orthocenter of a triangle with vertices (−8, 11), (−3, 11), and (−3, −12).
The orthocenter of triangle is at ( , ).
Answer:
( -3, 11)
Step-by-step explanation:
find the equation of the line between points ( -8, 11) and (-3, 11)
y= mx +b , where m is slope snd b is y-intercept
m = (y2-y1)/ (x2-x1) = 11-11/ -8- -3 = 0/ -5 = 0 ( if slope is o is a horizontal line)
y = 0x + b and pick a point to find b
11 = 0*-8 + b so b= 11
y = 11 is the equation of the line between points ( -8, 11) and (-3, 11) and the equation of its perpendicular line is x=-3
the equation of the line between points (-3, 11) and ( -3, -12) is x= -3 and the perpendicular to it is y= 11
so we have a right triangle so the ortho center is at (-3, 11) where the vertex of the 90 degree angle is
