Answer:

About 23.9 in

Step-by-step explanation:

We are given ;

a circle whose radius is 3.8 inches

we are required to determine the circumference

The circumference is given by the formula;

=2πr

Therefore;

Circumference = 2×3.14×3.8 in

=23.864 in

= 23.9 in

Therefore, the circumference of the figure is about 23.9 in

Answer:

$\theta=1.72$ radians

Step-by-step explanation:

Arc length and radius is given. So, we need to know the arc length formula for a circle.

That is:

$s=r\theta$

Where s is the arc length

r is the radius

$\theta$ is the angle (IN RADIANS)

We have:

s = 15.5

r = 9

Now, we substitute and find the angle:

$s=r\theta\\15.5=9\theta\\\theta=\frac{15.5}{9}\\\theta=1.72$

The angle, in radians, in 1.72

Answer:

y=4x+6

Step-by-step explanation:

when x=0 y=6

when x=1 y=10

when x=2 y=14

to find y=50:

50=4x+6

44=4x

11=x

x=11 when y=50

Dollar is worth three and 3 1/2 kruneros. What is the value of 43 3/4 kruneros?

Korvikt [17]

Question:

One dollar is worth 3 1/2 kruneros. What is the value of 43 3/4 kruneros?

Answer:

The value of $43\frac{3}{4}$ kruneros is 12.5 dollars

Solution:

Given that,

Dollar is worth three and 3 1/2 kruneros

Which means,

$1 \text{ dollar } = 3\frac{1}{2} \text{ kruneros }\\\\1 \text{ dollar } = 3.5 \text{ kruneros }$

We have to find the value of $43\frac{3}{4}$ kruneros

Let us convert the mixed fractions to improper fractions

Multiply the whole number part by the fraction's denominator.

Add that to the numerator.

Then write the result on top of the denominator.

$43\frac{3}{4} = \frac{43 \times 4 + 3}{4} = \frac{175}{4} = 43.75$

So we have to find the value of 43.75 kruneros

Let "x" be the value of 43.75 kruneros

Then,

1 dollar = 3.5 kruneros

x dollar = 43.75 kruneros

This forms a proportion and we can solve the sum by cross multiply

$1 \times 43.75 = x \times 3.5\\\\x = \frac{43.75}{3.5}\\\\x = 12.5$

Thus value of $43\frac{3}{4}$ kruneros is 12.5 dollars
