Answer:
14π cm
Step-by-step explanation:
Circumference of a circle given the diameter is :
πd
We simply substitute the value given in the image into our formula to find our answer:
πd = π×14 = 14π
Units will be cm as circumference is a length
This is our final answer as the question states to leave it in pi form .
Hope this helped and brainliest please
Answer:
34
Step-by-step explanation:
Distance - formula
1-4 will equal -3 because if you look on a number line and move 4 to the LEFT of 1 it will take you to -3. I hope this helps you! and have a great day!
The value of y when x = 5 is 45
<h3><u>Solution:</u></h3>
Given that y varies directly with x. This can be written mathematically as:
y ∝ x
---- eqn 1
Where "k" is the constant of propotionality
Given y = 27 when x = 3. Substitute these values in eqn 1
<h3>k = 9</h3>
Substitute k = 9 in eqn 1
y = 9x ----- eqn 2
<u><em>To find: y = ? and x = 5</em></u>
Substitute x = 5 in eqn 2
Thus the value of y when x = 5 is 45
Solving an equation is simply like solving an equation. For this problem, you must add 6 on both sides to get -0.8x alone. -10 + 6 would equal -4. Therefore, the inequality would look like this: -0.8x < -4
Now you have to divide -0.8 on both sides to have x alone. Since you are dividing a negative to the other side, the sign flips to >. When you divide -0.8 to -4, the answer would be 5. So therefore, the answer is: x > 5
In order to check this, you must plug in 5 into the x. -0.8 times 5 would equal -4. -4 - 6 would equal -10. -10 is the same as the other side. (-10 < -10) That means the answer would be correct. Hope this helps; cheers, mimiisawesome5
