Communicate Precisely: Suppose the numbers on the clock face are removed.
Write instructions that another person could follow to move the minute hand from 2 to 6.
In order to move the minute hand from 2 to 6 first move 60 degrees clockwise then 120 degrees clockwise.
What is a circle?It is described as a set of points, where each point is at the same distance from a fixed point (called the center of a circle)
We have:
On a clock, numbers 1 to 12 are printed on it.
If numbers on the clock face are removed.
As we know, the clock is a circle and has a total angle of 360 degrees.
Angle between the two numbers = 360/12 = 30 degree
Then the following instructions have to be followed in order to move the minute hand from 2 to 6:
Set the minute hand vertically up.Move 60 degrees in a clockwise direction, it will be on number 2.Now move 120 degrees in a clockwise direction, it will indicate the number 6.Thus, in order to move the minute hand from 2 to 6 first move 60 degrees clockwise then 120 degrees clockwise.

What is the value of x in the solution to this system of equations?
Answer:
x = 10/3
Step-by-step explanation:
3x = 2y + 14
y = -6x + 18
3x = 2(-6x+18) + 14
3x = -12x + 36 + 14
15x = 50
x = 50/15
x = 10/3
Answer:
10/3
Step-by-step explanation:
3x= 2y+14-------(1)
y= -6x+18------(2)
from equation (2) put y= -6x+18 into equation (1)
3x= 2(-6x+18)+14
3x= -12x+36+14
3x+12x= 50
15x= 50
dividing bothsides by 16
x = 50/15
x= 10/3

Answer: 19.62 * 10^7 cm
Step-by-step explanation:
Let a and b be rectangle sides.Area = a * bPerimeter = a + b + a + b = (a + b) * 2a = 9.2 * 10^7 cm
Area = 5.612 * 10^14 cm^2
Find: Perimeter - ?
Area = a * bb = Area / ab = (5.612 * 10^14) / (9.2 * 10^7) = 0.61 * 10^7 cm
Perimeter = (a + b)*2Perimeter = (9.2 * 10^7 + 0.61 * 10^7) * 2 = (9.2 + 0.61) * 10^7 * 2 = 9.81 * 2 * 10^7 = 19.62 * 10^7 cm

Find the lateral area and surface area of the regular square pyramid.
Round to nearest tenth.
Answer:
Step-by-step explanation:
lateral edge is an edge from the base to the vertex. As opposed to a base edge.
If the base edge is 6, the base diagonal is 6√2
Now draw a right triangle from the center of the base to the vertex, including one base corner.
(6√2/2)^2 + h^2 = (√34)^2
18 + h^2 = 34
h = 4
So, now we have height 4 and base edge 6, so the faces are triangles with
base = 6
height = √(3^2 + 4^2) = 5
lateral area is thus 4 * 1/2 (6)(5)
add the square base if desired.

Answer: x=7.7, y=40
3/x = 15/38.5
38.5*3=115.5
115.5/15= 7.7
x=7.7
3/8 = 15/y
15*8=120
120/3= 40
y=40

Write an equation in slope-intercept form for the relationship in the table.
The equation of the relationship in the table, in slope-intercept form, is: y = x + 5.
What is the Slope-intercept Form?The slope-intercept form for a relationship between two variables x and y is represented as: y = mx + b, where:
m = slope = change in y / change in xb = y-intercept.Slope (m) = change in y / change in x = 47 - 42 / 42 - 37 = 5/5
Slope (m) = 1
Substitute (37, 42) = (a, b) and m = 1 into y - b = m(x - a):
y - 42 = 1(x - 37)
y - 42 = x - 37
y = x - 37 + 42
y = x + 5
