Answer:

Circumference ≈ 82.9

Step-by-step explanation:

The formula for calculating the circumference of a circle is:

C = 2πr

Where 3.14 is pi (as stated on your screen)

And r is the radius.

Knowing this substitute those values

C = 2(3.14)(13.2)

Multiply 2 and 3.14.

C = (6.28)(13.2)

Multiply 6.28 and 13.2.

C = 82.9 when rounded.

Evaluate 0.67y + 4 when y = 2 and when y = -2
jarptica [38.1K]

Answer:

2.66 and 4.34

Step-by-step explanation:

To evaluate, substitute the values of y and solve.

So, when y =-2

0.67y + 4 = -1.34 + 4 = 2.66

And when y = 2

0.67y + 4 = 1.34 + 4 = 4.34

Hope this helps.

ArbitrLikvidat [17]

<u>Answer:</u>

• Equation = 2(\frac{7}{4}w  + w) = 176

• length = 56 ft

• width = 32 ft

<u>Step-by-step explanation:</u>

The ratio of the length to width is 7:4.

∴ \frac{l}{w} = \frac{7}{4}

⇒ l = \frac{7}{4} w                 [Equation 1]

We know that the perimeter of the garden is 176 feet.

∴ 2(l + w) = 176

⇒ 2(\frac{7}{4}w  + w) = 176

⇒ \frac{7}{4} w + w = 88        [From Equation 1]

⇒ \frac{7 w + 4w}{4}  = 88

⇒ \frac{11w}{4} = 88

⇒ 11w = 352

⇒ w = \bf 32 \space\ ft

We know from Equation 1 that:

l = \frac{7}{4} w

∴ l = \frac{7}{4} (32)

⇒ l = \bf 56 \space\ ft

Need help ASAP please and thank you
noname [10]

Answer:

-3m^{12}{n^{6} }

Step-by-step explanation:

To begin simplifying this, we can first divide the coefficients, giving us:

\frac{-3m^{5}n^{4}  }{m^{-7} n^{-2} }

We know that when dividing exponents, this means we need to subtract the exponent on the denominator from the numerator. This gives us:

\frac{-3m^{5+7} n^{4+2} }{1}

Now, simplifying this gets:

-3m^{12}{n^{6} }
