Answer:
Your in seventh grade too!
Step-by-step explanation:
So, in 240 miles can be made by 2 hours.
Do this equation:
240 × 2 = 480 / 4 hours.
You cannot do 3 because it won't fit another 240 miles.
Next, subtract the 480 miles from 600 miles.
600 - 480 = 120
Also, if you would've divided by 2 hours.
240 ÷ 2 = 120 / 1 hour
Add the hours.
4 + 1 = 5 hours
It takes 5 hours to travel 600 miles by the small plane.
Answer:
well let's see below.
Step-by-step explanation:
If you're simplifying the fractional form, the answer would be f(x) + x/2 =4.
Answer:
11.33 in. to the nearest hundredth.
Step-by-step explanation:
The perimeter of the shaded area = length of the 2 straight lines + the length of the 2 arcs = 4 + length of the 2 arcs.
Calculate the length of the outer arc:
This equals (30 / 360) * perimeter of the largest circle
= 1/12 * 2 π * 8
= 4/3 π in.
The inner circle has a radius of 8 - 2 = 6 ins
so the length of the inner arc
= 1/12 * π * 2 * 6
= π in.
So the perimeter of the shaded region = 4 + 4/3 π + π
= 4 + 7π/3
= 11.33 in.
The length of AD in the parallelogram is 143 cm.
<h3>How to find the side of a parallelogram?</h3>
A parallelogram is a quadrilateral with opposite sides parallel to each other. The opposite angles of a parallelogram are equal. Two adjacent or consecutive angles of a parallelogram are supplementary.
Hence,
2x + 72 + 2x - 20 = 180
4x + 52 = 180
4x = 180 - 52
4x = 128
divide both sides by 4
4x / 4 = 128 / 4
x = 32
Therefore,
∠A = 2(32) + 72 = 64 + 72 = 136 degrees
z = 136°
Therefore,
AC = BC = BD = AD
AC = z + 7
AC = 136 + 7
AC = 143 cm
Hence,
AD = 143 cm
