Answer:
the length is 98 meters
Step-by-step explanation:
to find the area of a rectangle we use the equation wl = a, you basically multiply the width by the length. If we only have the measurement of one side, but we have the area, then we can do this in reverse, by dividing the area by the known side. So we just need to divide 4704 by 48
4704 / 48 = 98
length is 98
#7 has a slope of 1/3 and #8 has a slope of 2/3
731=3x+2
731 - 2 = 3x+2 -2
729=3x
729/3 = 3x /3
243=x
Answer:
x = 10
Step-by-step explanation:
Let's draw the center of the circle S and the segments SE and SD.
SE is perpendicular to EF (as EF is tangent to circle).
That means FED + DES = 90deg
We also know that DSE = 120deg
And because the SED is an isosceles triangle, we know that angle measures for DES and SDE are equal.
DES = (180deg - 120deg) / 2 = 30deg
FED = 90deg - DES = 90deg - 30deg = 60deg
7x - 10 = 60
7x = 70
x = 10
Answer:
d=0.031746
Step-by-step explanation:
1. Add 4d to both sides: 3.2=2.3d+3+4d
2. Simplify 2.3d +3+ 4d to 6.3d+3: 3.2=6.3d+3
3. Subtract 3 from both sides: 3.2-3=6.3d
4. Simplify 3.2-3 to 0.2: 0.2-6.3d
5. Divide both sides by 6.3: 0.2/6.3=d
6. Simplify 0.2/6.3 to 0.031746: 0.031746=d
7. Switch sides: d=0.031746
Hope this helped!
