Answer: 5.3571
Step-by-step explanation:
The formula used to calculate direct proportion is: y = kx
We will find the constant of proportionality when y=10 and x=5.6. This will be:
y = kx
10 = 5.6k
k = 10/5.6
k = 1.7857143
The value of y when X=3 will be:
y = kx
y = 1.7857143 × 3
y = 5.3571
Subtract -3k from -2k
Answer:
k
Step-by-step explanation:
-3k minus -3k
-2k-(-3k)
-2k+3k
k

how do I find the area of this shape. Please help I need to turn this in today
Answer:
A = 70 units²
Step-by-step explanation:
Since all 4 sides are congruent then figure is a rhombus
The area (A) of a rhombus is calculated as
A = [tex]\frac{1}{2}[/tex] × d₁ × d₂ ( d₁ and d₂ are the diagonals )
Here d₁ = 7 + 7 = 14 and d₂ = 5 + 5 = 10 , then
A = [tex]\frac{1}{2}[/tex] × 14 × 10 = 7 × 10 = 70 units²
you roll a six sided die what is p(1)
Answer:
[tex]\frac{1}{6}[/tex]
Step-by-step explanation:
6 sides, so 6 is the denominator.
There is only one 1, so the numerator is 1.
Therefore p(1) = [tex]\frac{1}{6}[/tex]

Natasha conducted a survey to determine how many of the 215 workers in her office building use public transportation to get to work. She surveyed 30 randomly selected workers who entered the office cafeteria throughout the day. Of the 30 workers surveyed, 9 used public transportation to get to work.
Which change to Natasha's survey process would make the data more reliable?
A. Ask a randomly selected sample of people who use public transportation whether their office is in the building.
B. Use a different sample size so the predicted number of workers who use public transportation is a whole number.
C. Have workers complete a written survey so there is a written record of the responses.
D. Randomly select the sample in the lobby of the building so workers who do not enter the cafeteria can be included.

A ping-pong ball rolls forward 6 meters to the right, and bounces backward 3 meters to the left. It traveled a total displacement of.
Answer:
a displacement of 3 meters.
Step-by-step explanation:
you move 6 meters to the right, then 3 meters to the left
6 - 3 = 3
displacement is the distance away from the starting point
The ball traveled a total displacement of 3m.
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
<------------6m----------------->
Ball ____________________
Ball_________
<------3m------>
Distance traveled by the ball.
= 6 m + 3m
= 9 m
Displacement is the shortest distance traveled by the ball.
= 6 - 3
= 3m
Thus,
Displacement is 3m.

Somebody please help me plsssss
Given:
The radius of the cylinder = 2 cm
Height of the cylinder = 5 cm
To find:
The volume of the cylinder.
Solution:
We know that, the volume of a cylinder is:
[tex]V=\pi r^2h[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]r=2,h=5[/tex] in the above formula, we get
[tex]V=\pi (2)^2(5)[/tex]
[tex]V=\pi (4)(5)[/tex]
[tex]V=20\pi [/tex]
Therefore, the volume of the cylinder is [tex]20\pi [/tex] cubic cm and its approximate value is 62.832 cubic cm.
