Give your answer to 1 decimal place.
19 cm
PLEASE HELP
Step-by-step explanation:
Find the radius: 19 ÷ 2 = 9.5
4/3 x 22/7 x 9.5 x 9.5 x 9.5 = 3592
3592/3 =
1197.3 (Rounded to 1 decimal place)
Answer: 1197.3cm3
(I have never done area or perimeter of sphere before, but I did for other shapes. This is just my attempt using the methods I did for other shapes by the way)

What is the slope (-4,20) (-10,-17)
Answer:
The slope is 37/6
Step-by-step explanation:
m= (y2-y1)/(x2-x1)
m= (-17-20)/(-10+4)
m= (-37)/(-6)
m= 37/6

use the formula pi(3.14)r^2 h/3
Express the interval in set-builder notation. (-infinity,-8)
Answer:
8
Step-by-step explanation:
Simplify this expression. Assume that w is nonzero. Use pencil and paper. Describe how the values of the expression vary with the values chosen for w.
Give examples.
8w^0
Answer:
[tex]8w^{0} = 8[/tex]
Step-by-step explanation:
[tex]8w^{0}[/tex] ------------(1)
Assume any non-zero value of w (w=2)
Put this value in (1)
[tex]8(2)^{0}[/tex]
zero power of any number is 1. Therefore
[tex]8(2)^{0} = 8[/tex]
Assume any other non-zero value of w (w=100)
Put this value in (1)
[tex]8(100)^{0}[/tex]
we know zero power of any number is 1. Therefore
[tex]8(100)^{0} = 8[/tex]
For any non zero value of w answer will always be 8. Expression can be written in simplified form as
[tex]8w^{0} = 8[/tex]

Complete the point-slope equation of the line through (1, 3) and (5, 1). Use exact numbers.
Answer:
[tex]The \ equation \ in \ point \ and \ slope \ form \ is; \ y - 3 = -\dfrac{1}{2} \cdot (x - 1)[/tex]
Step-by-step explanation:
The coordinates of the points through which the line passes are (1, 3) and (5, 1)
The slope, m, of a line given the coordinates of two known points on the line, (x₁, y₁), (x₂, y₂) can be found as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
The slope of the given line is therefore [tex]m =\dfrac{1-3}{5-1} = \dfrac{-2}{4} = -\dfrac{1}{2}[/tex]
The equation of the line in point and slope form is therefore, y - y₁ = m·(x - x₁) or y - y₂ = m·(x - x₂)
Therefore, by substituting the known values, we have the equation in point and slope form as follows;
[tex]y - 3 = -\dfrac{1}{2} \cdot (x - 1)[/tex]
5. It took 400 rails to create one mile of track. Each rail had ten (10) spikes. Each spike needed three (3) strikes from a hammer. A fast crew could lay four (4) rails in one minute. Crews averaged five (5) miles of track per day. If the distance from Rock Island, Illinois to Sacramento, California is approximately 1800 miles: How many rails were needed? How many spikes were needed? How many hammer strikes were heard each hour? How many days were needed to complete the track?

The rectangular room measures 224 square feet long. One side of the room is 14 feet long. What is the perimeter of the room?
Answer:
60 feet
Step-by-step explanation:
Area of the rectangular room = Length * Width
Given
Area of the room = 224sq. feet
Length = 14 feet
Find the width first
A = LW
W = A/L
W = 224/14
W = 16 feet
hence the width of the room is 16 feet
Get the perimeter.
Perimeter = 2(L+W)
Perimeter of the room = 2(14+16)
Perimeter of the room = 2(30)
Perimeter of the room = 60 feet
Hence the perimeter of the room is 60 feet

Answer:
radious = 22Step-by-step explanation:
It's given that PL = PM
so the equation is
3x+4=6x-14
3x-6x=-14-4
-3x=-18
x=6
6x-14
6.6-14
36-14
22
Answer: 22
because PL = PN = PM => P is the centre of the inscribed circle of ΔHJK
=> the radius = PL =PM =PN
because PL = PM
=> 3x + 4 = 6x - 14
⇔ 3x = 18
⇔ x = 6
=> PL = 3.6 + 4 = 22

If I’m 24 in 1979 what year was I born in?
Answer:
1950
Step-by-step explanation:
If you were 24 in 1974, simply subtract 24 from 1974 to find what year you were born in:
1974-24= 1950
Of course, it may be +/- 1 depending on what month you were born in, and what month it is now!
I hope this helps! :)
What is the value of x in the equation x − 7 = 11?
a) 1.57
b) 4
c )15
d) 18
Answer:
18
Step-by-step explanation:
Take x-7=11 and then reverse what the 7 is doing in the equation.
11 + 7 = 18
Plug in 18 to double check.
18 - 7 = 11

If x is the measure of an angle, find the complement of the angle
A. x - 90
B. x - 180
C. 90 - x
D. 180 - x
Answer:
If x is the measure of an angle, the complement of the angle is (90-x).
C. (90-x) is the right answer.The complement of the angle x will be 90° - x. Then the correct option is C.
What is an angle?The angle is the distance between the intersecting lines or surfaces. The angle is also expressed in degrees. The angle is 360 degrees for one complete spin.
Complementary angle - Two angles are said to be complementary angles if their sum is 90 degrees.
If x is the measure of an angle. The complement of the angle x will be
Let y be the complementary angle of x. Then we have
x + y = 90°
y = 90° - x
The complement of the angle x will be 90° - x. Then the correct option is C.

does the data in the table show a proportional relationship?
Answer:
Yes.I divided 22.5 by 3, and got 7.522.5/3=7.5
I then added 7.5 from 22.522.5+7.5,
and I got 30.Once I got into the bigger numbers, I just multiplied 7.5 by the last number7x7.5= 52.5
All the numbers were constantly added by 7.5, so
the table is a proportional relationship.I hope this helped! +*♡
