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.

Answer:

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

• length = 56 ft

• width = 32 ft

Step-by-step explanation:

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

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:

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