Answer:
8/pi or approximately 2.55 ft
Step-by-step explanation:
The formula for the circumference is
C = 2 * pi *r
16 = 2 * pi *r
Divide each side by 2 pi
16 / ( 2 pi) = 2 * pi * r/ ( 2 pi)
8 / pi = r
Using 3.14 for pi
8 / 3.14 = r
2.54777 = r
2.55 =r
Answer:
Radius ≈ 2.55 ft.
Step-by-step explanation:
GIVEN :-
Circumference of circle = 16 ft.TO FIND :-
Radius of the circleFORMULAE TO KNOW BEFORE SOLVING :-
For a circle with radius 'r' & circumference 'c' ,
[tex]r = \frac{c}{2\pi }[/tex]
SOLUTION :-
[tex]Radius = \frac{Circumference}{2\pi } = \frac{16}{2\pi } = \frac{8}{\pi } = 2.55 ft. (appx)[/tex]
How many coins make $7.68 in cents
Find x. Round to the nearest tenth
A: 5.0
B: 7.8
C: 3.9
D: 4.6
Answer:
D
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos40° = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{x}{6}[/tex] ( multiply both sides by 6 )
6 × cos40° = x , then
x ≈ 4.6 ( to 1 dec. place ) → D
Find the area of the triangle
The area is __yd^2
Answer:
area of triangle = 4.5*6/2 = 13.5 sq.yd.
Step-by-step explanation:
The area of a right triangle is half of the product of the sides adjacent to the right angle.
Here the sides adjacent to the right angle are 6 yd and 4.5 yd.
Therefore the
area of triangle = 4.5*6/2 = 13.5 sq.yd.

A recipe for lemonade requires 10 parts of water to every 6 parts of lemon juice. How many cups of water should be added to 30 cups of lemon juice to make the lemonade? I dont understand how many "parts" of water = 1 cup
Answer:
50 cups
Step-by-step explanation:
ratio of water to juice = 10 : 6 = 5 : 3
amount of cup = (5 x 30) / 3 = 50

can someone please help with this i don’t know how to do it 85points
Answer:
Step-by-step explanation:
You can find the area by cutting it across in the middle into a trapezoid and a rectangle.
The trapezoid will have:
height = 10-4 = 6ft
top = 9-6 = 3ft
bottom = 8ft
So its area = 1/2*(3+8)*6 = 33 ft^2
The rectangle will have:
length = 10ft
width = 6ft
So its area = 10*6 = 60 ft^2
Total area = 60+33 = 93 ft^2
Answer:
93 ft^2.
Step-by-step explanation:
Divide the figure into 3 shapes; a triangle (top), and two rectangles (one in the middle and one on the bottom).
First find the area of the rectangle;
10*6 = 60 save that for later;
The dimensions of the second rectangle are not given but you can solve for them.
The width of the base of the second rectangle will be 10ft. - 4 ft. , this is because the base of the first rectangle is part of the base of the second rectangle with a length of 4 ft cut off.
The height of the second rectangle is given by 9ft. - 6ft.
Multiply the width (base) and height;
6*3=18
The base of the triangle is the same as the second rectangle's. Use that for the base. The height is given by 8-(the height of the second rectangle). The height is 5 and the base is 6.
1/2(5*6) = 15
Add all of the values together;
15+18+60 = 93 ft^2
If tanΘ = 6/5 and cosΘ < 0, what is sin2Θ?
An explanation on how to solve this problem would be great, thanks!!
Answer:
[tex]\displaystyle \sin2\theta=\frac{60}{61}[/tex]
Step-by-step explanation:
We are given that:
[tex]\displaystyle \tan\theta=\frac{6}{5}\text{ and } \cos\theta <0[/tex]
And we want to find the value of sin(2θ).
First, recall that tangent is the ratio of the opposite side to the adjacent side.
Therefore, the hypotenuse is:
[tex]h=\sqrt{6^2+5^2}=\sqrt{61}[/tex]
Next, note that tangent is positive and cosine is negative. Tangent is positive in QI and QIII. Cosine is negative in QII and QIII.
Hence, we can conclude that θ must be in QIII.
In QIII, sine is negative, cosine is negative, and tangent is positive.
And with respect to θ, our opposite side is 6, adjacent side is 5, and the hypotenuse is √(61).
We can rewrite our expression as:
[tex]\sin2\theta=2\sin\theta\cos\theta[/tex]
Using the above information, substitute:
[tex]\displaystyle =2\left(-\frac{6}{\sqrt{61}}\right)\left(-\frac{5}{\sqrt{61}}\right)[/tex]
Simplify. Hence:
[tex]\displaystyle \sin2\theta=\frac{60}{61}[/tex]
Simplify for ez quick points!

Given the conversion factor 12/1 in over 1ft, which cube has the larger surface area?
Answer:
Solid A
Step-by-step explanation:
3 feet is 3 x 12 = 36 inches, which is less than 48 inches, so solid A has a larger surface area than solid B.
What is the image point of (2,7) after a translation left 4 units and up 2 units?
Please hurry ASAP no links
Answer:
Coordinates of the image point → (-2, 9)
Step-by-step explanation:
If a point (x, y) is translated by 'h' units left and 'k' units up then the rule for the translation will be,
(x, y) → (x - h, y + k)
Rule for the translation of a point (2, 7) by shifting 4 units left and 2 units up will be,
(2, 7) → (2 - 4, 7 + 2)
→ (-2, 9)
Coordinates of the image point → (-2, 9)
the only solution to x² + bx + c = 0
is x = 5
work out the values of b and c
Answers:
b = -10
c = 25
=================================================
Explanation:
If x = 5 is the only solution then (x-5) is the only factor. Turns out we have repeated solutions and repeated factors. Meaning (x-5)(x-5) = (x-5)^2 is what we're after.
Expand that out to get
(x-5)^2
x^2 - 5x - 5x + 25
x^2 - 10x + 25
Then compare this to x^2 + bx + c to find
b = -10
c = 25
If you were to solve x^2-10x+25 = 0, you'll find that x = 5 is the only root.
PLEASE HELP ME I WILL HIVE BRAINLYEST
Answer:
Step-by-step explanation:
a). Points on a number line are,
x = -7, 1
Number of small blocks between x = -7 and 1 is 8.
Distance = 8
b). Difference between two points x = -7, 1 will be,
1 - (-7) = 1 + 7
= 8
-7 - 1 = -8
c). Absolute value of each difference,
|1 - (-7)| = 1 + 7
= 8
|-7 - 1| = |-8|
= 8

given a set of numbers (0,1,2,3,4,5,6) if one of the set is chosen at random, find the
probability that the number is a solution of 3x-4 < 11
Answer:
This probability is 5/7
Step-by-step explanation:
Rewriting this problem may make it appear to be more manageable.
The probability that the number is a solution of 3x-4 < 1 simplies to "x < 5".
This probability is 5/7, since {0, 1, 2, 3, 4} are all less than 5.

If a movie begins at 5:10 p.m. and runs for 1 hour and 45 minutes, what time will the movie end?
(Answer:_:__p.m.)
Answer:
6:55 p.m
Step-by-step explanation:
Hour connects with hour therefore, 5 + 1 = 6
Minutes connects with minutes thus, 10 + 45 = 55
Hence it being 6:55 p.m when the movie finishes if it starts at 5:10 p.m.

Is this an enlargement or a reduction? How do you know?
Answer:
Reduction
Step-by-step explanation:
The resulting shape M'S'V' is smaller than the original shape MSV, so it is therefore classified as a reduction.
Use what you know about similarity and proportions to solve for x in the triangles below. Show all work.
4
10
5
x + 5
Answer:
Value of x = 7.5 unit
Length of side = 12.5 unit
Step-by-step explanation:
Given that both triangles are similar because all angles are equal;
So, the ratio of similar lines is in the same proportion.
[x + 5] / 5 = 10 / 4
4[x + 5] = 50
4x + 20 = 50
4x = 50 - 20
4x = 30
x = 30 / 4
x = 7.5
So,
Value of x = 7.5 unit
Length of side = x + 5
Length of side = 7.5 + 5
Length of side = 12.5 unit
