A circle has a radius of 23.85 inches.
What is the circumference of this circle?
Use 3.14 for pi. Round your final answer to the nearest tenth.
74.9 inches
1786.1 inches
149.8 inches
Please help
The circumference formula is 168.6
where r is the radius given to us as 26.85, and pi is to be 3.14. In our formula then, we have
.
Doing that multiplication and rounding to the nearest tenth leaves us with a circumference of 168.6 inches.
The point (-6, 4) lies on a straight line that has a gradient of -2. What is the
equation of this line?
Given:
Point on straight line = (-6,4)
Gradient = -2
To find:
The equation of the line.
Solution:
Point-slope form: If a line passes through the point [tex](x_1,y_1)[/tex] with slope m, then the equation of the line is
[tex]y-y_1=m(x-x_1)[/tex]
The line passes through the point (-6,4) with slope -2. So, the equation of the line is:
[tex]y-4=-2(x-(-6))[/tex]
[tex]y-4=-2(x+6)[/tex]
[tex]y-4=-2x-12[/tex]
Adding 4 on both sides, we get
[tex]y-4+4=-2x-12+4[/tex]
[tex]y=-2x-8[/tex]
Therefore, the equation of the line is [tex]y=-2x-8[/tex].
The area of a rectangle is 14 square units. It has side lengths a and b. Given the following value for a, find b. a = 2 & 1/3
Given:
The area of a rectangle = 14 square units.
The side lengths are a and b.
[tex]a=2\dfrac{1}{3}[/tex]
To find:
The value of b.
Solution:
We know that, the area of a rectangle is:
[tex]Area=Length\times Width[/tex]
The area of the given rectangle is:
[tex]14=a\times b[/tex]
[tex]14=2\dfrac{1}{3}\times b[/tex]
[tex]14=\dfrac{2(3)+1}{3}b[/tex]
[tex]14=\dfrac{6+1}{3}b[/tex]
On further simplification, we get
[tex]14=\dfrac{7}{3}b[/tex]
[tex]14\times 3=7b[/tex]
[tex]42=7b[/tex]
Divide both sides by 7.
[tex]\dfrac{42}{7}=b[/tex]
[tex]6=b[/tex]
Therefore, the value of b is 6 units.

A man runs at a speed of 8 m/s for 15 seconds. Calculate how far it travles.
Answer:120 meters
Step-by-step explanation:
8 × 15
Answer:
120 m
Step-by-step explanation:
Speed = 8 m/s
Distance traveled in 1 sec = 8 m
Distance traveled in 15 sec = 8 * 15 = 120 m
If y varies inversely as x, and y = 4 when x = 16, what is the value of y when x = 8?
I suppose that the value of y equals 2, seems how 4 times 2 what equal 8 and 8 times 2 would equal 16

Gavin, Harry and Isabel each earn the same monthly salary.
Each month,
Gavin saves 28% of his salary and spends the rest of his salary
3
Harry spends
of his salary and saves the rest of his salary
4
the amount of salary Isabel saves: the amount of salary she spends = 3:-
Work out who saves the most of their salary each month.
You must show how you get your answer.
Answer:
isabel saves the most of their salary each month
Step-by-step explanation:
Let us assume the Salary of Gavin, Harry & Isabel be $100
Since
Gavin saves 28%
So his saving amount is Gavin
= 28% of $100
= $28
As harry spends 3 ÷ 4 of his salary
So Harry Spenings is
= (3 ÷ 4) of $100
= $75
Now
Harry Saving is
= $100 - $75
= $25
Also the ratio between isabel saves, and spend is 3:7
3k + 7k = 10k = 100S
k = $10
Now
the amount of salary isabel saves
= 3k
= 3 × $10
= $30
Now
$30 > $28 > $25
i.e.
isabel Saving > Gavin Savings > Harry Savings
Hence, isabel saves the most of their salary each month
A soccer ball is kicked toward the goal. The height of the ball is modeled by the function h(t) = −16t2 + 48t, where t equals the time in seconds and h(t) represents the height of the ball at time t seconds. What is the axis of symmetry, and what does it represent?
t = 3; It takes the ball 3 seconds to reach the maximum height and 3 seconds to fall back to the ground.
t = 3; It takes the ball 3 seconds to reach the maximum height and 6 seconds to fall back to the ground.
t = 1.5; It takes the ball 1.5 seconds to reach the maximum height and 3 seconds to fall back to the ground.
t = 1.5; It takes the ball 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.
Answer:
The function is a parabola of the form . The the formula for the axis of symmetry of a parabola is. So it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.
Answer:
D. it takes 1.5 seconds to reach the maximum height and 1.5 seconds to fall back to the ground.

What is a graph?A graph, which is a diagrammatic depiction of a network, describes the connection between lines and points. A graph consists of various points and the separation between two of them.
It doesn't matter how much time the lines are or where the points are located. A node is a name for each constituent in a graph.
For example to draw the equation y = 6x +9 this will draw a straight line in the coordinate geometry.
The solution of any equation is a point of intersection of a graph as we can see that the graph which is present in the question has only one intersection so there will be only one answer.

find the length of the bold arc. Round your answer to the nearest tenth.
Answer:
62.83 m
Step-by-step explanation:
Given that,
The radius of the circle, r = 15 cm
Major angle = 240°
We need to find the length of the bold arc. The formula used to find the arc length is given by :
[tex]l=\dfrac{\theta}{360}\times 2\pi r\\\\=\dfrac{240}{360}\times 2\pi \times 15\\\\=62.83\ m[/tex]
So, the length of the bold arc is equal to 62.83 m.

Line p has a slope of -7/8
Line q is parallel to line p. What is the slope of line q?
Simplify your answer and write it as a proper fraction, improper fraction, or integer.
Answer:
The slope of line q is [tex]-\frac{7}{8}[/tex].
Step-by-step explanation:
We know that line p has a slope of [tex]-\frac{7}{8}[/tex], and that line p and line q are parallel. Parallel lines always have the same slope. Thus, the slope of line q must be [tex]-\frac{7}{8}[/tex] as well.

The coordinate of A` is (5,5) , the coordinate of B` is (5,1), the coordinate of C` is (2,1) and the coordinate D` is (1,5).
What is the coordinate of a point?A pair of number that describes the exact position of a point on a cartesian plane by using the horizontal and vertical lines is called the coordinate of a point. Coordinates are usually denoted by (x, y).
From the figure we can see that A` is 5 unites right of vertical line and 5 unit upward the horizontal line. So, the coordinate of A` is (5,5).
Similarly, B` is 5 unit right of vertical line and 1 unit upward the horizontal line. So, the coordinate of B` is (5,1).
C` is 2 unit right of vertical line and 1 unit upward the horizontal line. So, the coordinate of C` is (2,1).
And, D` is 1 unit right of vertical line and 5 unit upward of horizontal line. So, the coordinate of D` is (1,5).
Hence the coordinates of A`B`C`D` is (5,5), (5,1), (2,1) and (1,5) respectively.
