Answer:

<em>I) R = 3 cm;</em>

<em>II) V = 14.3 cm³.</em>

Step-by-step explanation:

<em>I) C = 94.2 ÷ 5 = 18.84</em>

<em>A cylinder has a base with a circumference of 18.84cm.</em>

<em /> $R=\dfrac{C}{2\pi } =\dfrac{18.84}{2 \cdot 3.14} =\dfrac{18.84}{6.28} =3 \: (cm)$ <em />

<em />

<em>II) </em> $V=\pi R^{2}H=3.14 \cdot 3^{2} \cdot 5 = 141.3 \: (cm^{3})$ <em />

1. Stacy owns a hair salon and haircuts are $10. She charges hairdressers $20 per hour to rent a chair and serve clients. What i

VashaNatasha [74]

Let us make an equation to solve :
Y=mx+b (general form of a linear equation)
y=10x-20 (x is the number of haircuts,y is the amount she earns)
the minimum amount to carry out all the expenses is $20
so,
20=10x-20
20+20=10x
40=10x
40/10=x
4=x
so she must do 4 haircuts in an hour

I have no idea how to do this one please help

Nuetrik [128]

Answer:

a = -14

Step-by-step explanation:

We are given

$\frac{2a+38}{5} = 2\\$

We want to get the variable by itself. First, we can multiply both sides by 5 to get rid of the fraction

$\frac{(2a+38)(5)}{5} = (2)(5)\\2a + 38 = 10$

Now we can isolate the variable by subtracting 38 from both sides

$2a + 38 - 38 = 10 - 38\\2a = -28\\a = \frac{-28}{2}\\a = -14$

Aliun [14]

Answer:

46.67 cubic feet

Step-by-step explanation:

Given :The rectangular base is 35 square feet, with a height of 4 feet.

To Find :What is the volume of the tent?

Solution :

Volume of rectangular base pyramid =

Since we are given that The rectangular base is 35 square feet, i.e. area of rectangular base = l*w = 35 sqaure feet

Height of pyramid h = 4 feet

Putting values in formula

Volume of rectangular base pyramid =

=

=46.67 cubic feet

Thus volume of the tent is 46.67 cubic feet

Answer:

4

Step-by-step explanation:

Simplify x and y by rationalising the denominator of both

To rationalise the denominator multiply the numerator/ denominator by the conjugate of the denominator.

The conjugate of 2 + $\sqrt{3}$ is 2 - $\sqrt{3}$

The conjugate of 2 - $\sqrt{3}$ is 2 + $\sqrt{3}$

x = $\frac{1(2-\sqrt{3)} }{(2+\sqrt{3})(2-\sqrt{3}) }$ = $\frac{2-\sqrt{3} }{4-3}$ = 2 - $\sqrt{3}$

y = $\frac{1(2+\sqrt{3}) }{(2-\sqrt{3})(2+\sqrt{3}) }$ = $\frac{2+\sqrt{3} }{4-3}$ = 2 + $\sqrt{3}$

Thus

x + y = 2 - $\sqrt{3}$ + 2 + $\sqrt{3}$ = 4
