<h2>Question:-</h2>

The circumference of a circle is 9.04 cm. Find the length of the diameter.

<h2>Solution:-</h2>

Let the radius of a circle be r cm.

We know the formula of circumference of a circle is 2πr.

ATQ ,

2πr = 9.04

2 × $\frac{22}{7}$ × r = 9.04

$\frac{44}{7}$ × r = 9.04

r = $\frac{9.04 \: × \: 7}{44}$

r = $\frac{63.28}{44}$

r = 1.438

Now, as we have to find the length of the diameter ,

So, we know, Diameter (d) = 2 × radius (r)

$\therefore$ d = 2r

Hence, d = 2 × 1.438 ( r = 1.438 )

d = 2.876

d = 2.88 ( approx )

<h3>The length of the diameter is 2.88 cm. [Answer]</h3>

Julli [10]

Step-by-step explanation:

Probability of event A on the condition of event B is:

P(A|B) = P(A and B) / P(B)

P(scored an A | girl) = P(scored an A and girl) / P(girl)

P(scored an A | girl) = 0.35 / 0.45

P(scored an A | girl) = 0.778

The probability that a randomly selected girl also scored an A is 77.8%.

Find the slope trough (-22,3) and (11,-3)

velikii [3]

Answer:

The slope is $-\frac{2}{11}$

Step-by-step explanation:

Let $(x_1,y_1)=(-22,3)$ and $(x_2,y_2)=(11,-3)$

The slope is given by;

$m=\frac{y_2-y_1}{x_2-x_1}$

We plug in the values to get;

$m=\frac{-3-3}{11--22}$

Simplify;

$m=\frac{-6}{33}$

$m=-\frac{2}{11}$

ra1l [238]

Answer:

The length of the shortest side on the blueprint is 10 centimeters.

Step-by-step explanation:

Given:

George is an landscape architect and is designing his backyard in a blueprint. In the yard, he wants a garden in the shape of a triangle. The length of the longest side of the garden will be 600 centimeters, and the length of the shortest side of the garden will be 400 centimeters. If the length of the garden's longest side on the blueprint is 15 centimeters.

Now, to find the length of the shortest side on the blueprint by using an equation.

Let the length of the shortest side on the blueprint be $x.$

The length of the garden's longest side on the blueprint = 15 centimeters.

The length of the longest side of the garden = 600 centimeters.

The length of the shortest side of the garden = 400 centimeters.

If, 600 centimeters is equivalent to 400 centimeters.

So, 15 centimeters is equivalent to $x$ .

Now, to set an equation that can be used to get the length of the shortest side on the blueprint through cross multiplication method:

$\frac{600}{400} =\frac{15}{x}$

By cross multiplying we get:

$600x=6000$

Dividing both sides by 600 we get:

$x=10.$

Therefore, the length of the shortest side on the blueprint is 10 centimeters.

the cost of running an appliance varies jointly as the number of watts used, the hours of operation, and the cost per kilo-watt

zhuklara [117]

Suppose:
C=cost
c=cost per kilo-watt hour
w=number of watts
h=number of hours
thus
C=kwhc
where:
k=constant of proportionality:
k=C/(whc)
but
C=15 when w=6000, h=10/60=1/6 hours, c=7.5 cents per kw/h
thus
k=15/(6000*1/6*7.5)
k=0.002
thus:
C=0.002(whc)
hence:
when
h=70*2=140=140/6=70/3 hours the cost will be:
C=0.002(6000*70/3*7.5)
C=2100 cents
C=$21
