Answer:
15 feet
Step-by-step explanation:
if the dog run is a rectangles then the formula for the perimeter is 2h+2l
if we plug in the numbers we know we get this:
2h+2(5)=40
2h+10=40
2h=30
h=15
2 feet
Step-by-step explanation:
4+4= 8
12-8=4
4 divided by 2= 2 feet :)
Answer:
115
Step-by-step explanation:
angle DEF is an inscribed angle and arc DF is the arc it intercepts
if you didn't know an inscribed angle is equal to half the measure of the arc it intercepts
Hence angle DEF = 1/2 of arc DF
If arc DF = 230 then angle DEF = half of 230 or 230/2
230/2=115
Hence angle DEF = 115
Answer:
width x-9 meters
Step-by-step explanation:
(x²-x-72)÷(x+8)
= x-9
Answer:
Step-by-step explanation:
<u>The ratio is given:</u>
<u>Let each equal part be x, then we have:</u>
- b - r = 6
- 9x - 6x = 6
- 3x = 6
- x = 2
<u>Total number of counters:</u>
- 2(9 + 6 + 3) = 2(18) = 36
