Answer:

B= 6

Step-by-step explanation:

pythagorean theorem formula is a² + b² = c²

so: 8² + b² = 10²

then: 64 + b² = 100

subtract 64 from both sides to get b²= 36

square root 36 and you get 6 for b

answer: B= 6

Answer:

r = 8 ft

Step-by-step explanation:

The formula for circumference of a circle is

C = 2 * pi *r

We know the circumference is 16 pi

16 pi = 2 pi r

Divide each side by 2pi

16 pi /2 pi = 2 pi r / (2pi)

8 = r

Three less than one-fourth of the product of eight thirds and nine. Please write equation, then solve.
kenny6666 [7]
Put simply, you have to work backwards in making the equations. Start with the product of 8/3 and 9.
\frac{8}{3}*9

 Next take 1/4 of that. This can be done in two ways, either multiplying by 1/4:
(\frac{8}{3}*9)*\frac{1}{4}

, or dividing everything by 4.
(\frac{8}{3}*9)/4

Finally, subtract three.

The final equation would read:
((\frac{8}{3}*9)*\frac{1}{4})-3



Using PE(M/D)(A/S), we'd start with \frac{8}{3}*9

3 and 9 cancel out to be 1 and 3, leaving us with \frac{8}{1}, or 8, and 3 and this part of the equation reading 8*3, which is 24.

The next step is \frac{24}{4}, which is 6.

Lastly we subtract 3 from six, leaving us 3.

The perimeter of a rectangular is 58 cm. The length is 5 more than twice the width.
riadik2000 [5.3K]
<h3>Answer:</h3>

a) l = 5 + 2w

b) P = 2(l +w) = 2(5 +2w +w)

c) w = 8 cm, l = 21 cm

<h3>Explanation:</h3>

a) Using w for width, twice the width is 2w, and 5 more than that is 5+2w. This is your expression for l:

... l = 5 + 2w

b) The perimeter is the sum of the lengths of all sides, so is the sum of twice the length and twice the width.

... P = 2(l +w) = 2(5 +2w + w) . . . . substituting for l using the expression of (a)

c) Substituting the given perimeter, we have ...

... 58 = 2(5 +3w) = 10 + 6w . . . . . collect terms, eliminate parentheses

... 48 = 6w . . . . . . . . . . . . . . . . . . subtract 10

... 8 = w . . . . . . . . divide by 6

... l = 5 + 2·8 = 21 . . . . . find length using the formula for it

Dimensions are in centimeters, so we can write the solution as ...

  • width = 8 cm
  • length = 21 cm
