Price of one soda is B , 0.40
x+y=1.45
2x+y=2.5

Solve simultaneous equation for y
You will get 0.4

Answer:

$0.40

Step-by-step explanation:

let a hamburger be X and soda b y

then X + Y is equals to 1.45

2 X + Y is equals to 2.50

using elimination method we will fine the value of x

2 X + Y = 2.50

X = 1.05

now how to find the value of Y

we know that X + Y = 1.45

putting the value of x

we get Y is equals to 1.45-1.05

$0.40

A circle with radius of 2cm sits inside a circle with radius of 4cm What is the area of the shaded region

Klio2033 [76]

ANSWER

$12\pi \: {cm}^{2}$

EXPLANATION

We want to find the area of the shaded region.

We find the area of the smaller circle and subtract from the area of the larger circle.

Area of smaller circle is

$a = \pi \: \times 2^{2} = 4\pi$

Area of larger circle is

$A = \pi \: \times {4}^{2} = 16\pi$

The area of the shaded region is:

$16\pi - 4\pi = 12\pi$

A real estate sales agent receives a salary of $250 per week plus a commission of 2% of sales.Write an equation that gives the w

lisabon 2012 [21]

The equation y=0.02x+250 gives the weekly income y in terms of sales x.

Step-by-step explanation:

Given,

Weekly salary of real estate agent = $250

Commission rate = 2%

Let,

x be the sales per week.

y be the total weekly income.

Amount of commission = 2% of sales per week

Amount of commission = $\frac{2}{100}*x$

Amount of commission = 0.02x

Total weekly income = Amount of commission + Weekly salary

$y=0.02x+250$

The equation y=0.02x+250 gives the weekly income y in terms of sales x.

Question 2

BabaBlast [244]

Answer:

The equation of the required line is y = x + 5

Step-by-step explanation:

The equation of the given line is y = x - 2

The required line = A line parallel to the given line

The point through which the required line passes = (-3, 2)

The general form of the equation of a straight line, is y = m·x + c

Where;

m = The slope of the line

By comparison, the slope of the given line, m = 1

When two lines are parallel, their slope are equal

Therefore, the slope of the required line = m = 1

The equation of the required line in point and slope form is therefore;

y - 2 = x - (-3) = x + 3

∴y = x + 3 + 2 = x + 5

The equation of the required line is therefore;

y = x + 5.

According to a report, 67.5% of murders are committed with a firearm. (a) If 200 murders are randomly selected, how many wou

kolezko [41]

Answer: The answer is 135 murders.

Step-by-step explanation: The report tells us that statistically 67.5% of murders are committed using a firearm. It follows therefore that in a sample of 200 randomly selected murders, one would expect that 67.5% of those would be by a firearm. $\frac{67.5}{100}$ * 200 = 135.

It would certainly be higher that the expected value based on previous data collected but it would not be unusual because one sample may have a higher than "normal" amount of murders by firearm. Statistics aren't going to be exact for every sample.
