Answer:

Step-by-step explanation:

s=18, t=18 the s gives t x sweets

s=18-x, t=18+x, s eats 5 and t eats half

s=18-5-x, t=(18+x)/2

Reamining sweets is

R=s+t

R=18-5-x+(18+x)/2

R=13-x+(18+x)/2

R=(26-2x+18+x)/2

R=(44-x)/2

Find the length of STV in the figure.

o-na [289]

Answer: The length of STV is about 76.83 in.

Step-by-step explanation:

The length of an arc is given by :-

$l=\frac{\theta}{360^{\circ}}\times2\pi r$ , where r= radius of the cirle, $\theta$ is the central angke made by arc.

As per given , Radius of the circle : r= 20 in

Central angle of arc SCV = $140^{\circ}$

Then, Central angle of arc SCV = $360^{\circ}-140^{\circ}=220^{\circ}$

Then, the length of the arc STV =

$l=\frac{220^{\circ}}{360^{\circ}}\times2(\frac{22}{7}) (20)\\\\=\frac{11}{18}\times\frac{880}{7}\\\\=76.8253968254\approx76.83\text{ in.}$

Hence, the length of STV is about 76.83 in.

A car uses 1 1/8 gallons of gas to go 13 1/2<br> miles. What is the rate of miles per gallon?

IceJOKER [234]

Answer:

1 1/8 ga / 13.5 mi = .0833 ga / mi

1 / .0833 ga/mi = 12 mi / ga

or .0833 ga/mi * 13.5 mi = 1.25 ga
