Width: x
length: x + 4
Equation: 2(x + x + 4) = 56
2(2x + 4) = 56
4x + 8 = 56
4x = 48, x = 12
Width = 12, 12 + 4 = length
Solution: the length is 16 inch
0.004 is read as four-thousandths, so write it as fraction using a 4 in the numerator and a 1000 in the denominator. Then reduce it.
0.004 = 4/1000 = 1/250
0.004 hours = 1/250 hours
The surface area of a cylinder is define by the formula S.A.=2πrh+2<span>πr^2, where the first part of the formula refers to the lateral area, perimeter, or circumference and the second part to the area of the bases, which are circles.
On this exercise it is asked to find the lateral area of a cylinder whose radius is 6 cm, and has a height of 20cm. To find the lateral area of the cylinder you should substitute this values into the formula, S.A.=2</span>πrh, and as can be seen the answers are given in terms of <span>π or pi.
S.A.=2</span><span>πrh
S.A.=2</span><span>π(6cm)(20cm)
S.A.=2</span><span>π(120cm)
S.A.=240</span>π cm^2
The lateral area of the cylinder is 240<span>π cm^2 or in other words letter B from the given choices.</span>
Answer:
48 feet of fence
Step-by-step explanation:
A rectangle has 4 sides, the parallel sides are equal to each other in length.
If Hector used 14 feet of fence on the long side, he used 28 feet in total for both long sides.
If Hector used 10 feet for the width/short side, he used 20 feet in total for both short sides.
Put simply: (14 x 2) + (10 x 2) = 48 feet of fence in total
Answer:
subtract 7 from both sides
2x < 7- 7
subtract 7 from 7 to get 0
2x < 0
product of two numbers is < 0 if one is > 0 and the other is < 0. since 2> 0, must be < 0.
x < 0
