$1 = 3.70 rands

$450 is simply 450 times $1, so multiply the conversion equation above by 450 on both sides.

450 * $1 = 450 * 3.70 rands

$450 = 1665 rands

How many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water?

RoseWind [281]

Answer:

The number of 1/5 liter glasses that Lin can fill is $7\frac{1}{2}$

Step-by-step explanation:

we know that

To find out how many 1/5 liter glasses can Lin fill with a 1 1/2 liter bottle of water, divided 1 1/2 by 1/5

$1\frac{1}{2} :\frac{1}{5}$

Convert mixed number to an improper fraction

$1\frac{1}{2}=1+\frac{1}{2}=1\frac{1*2+1}{2}=\frac{3}{2}$

substitute

$\frac{3}{2} :\frac{1}{5}$

Multiply in cross

$\frac{5*3}{2*1}=\frac{15}{2}=7.5$

Convert to mixed number

$7.5=7+\frac{1}{2}=7\frac{1}{2}$

A museum groundskeeper is creating a semicircular statuary garden with a diameter of 29 feet. There will be a fence around the g

Jlenok [28]

Answer:

The fence will cost $330.09

Step-by-step explanation:

First we have to calculate the perimeter of the semicircle for that we use the following formula:

d = diameter = 29ft

s = perimeter of semicircle

π = 3.14

s = d * 1/2 * π

we replace the values that we know

s = 29ft * 1/2 * 3.14

s = 45.53ft

Now we multiply the number of feet by the price of 1 foot of fence

45.53 * $7.25 = 330.0925

Rounding to the nearest hundredth

$330.0925 = $330.09

What is the x-value in the solution to this system of linear equations?

alexgriva [62]

First put the first equation in Y= which is:
Y=2x-11
So we can substitute this in for Y.
X+3(2x-11)=-5
Now solve for X
X+6x-33=-5
7X=28
X=4
