Answer:

The cost of meal is: $20

Step-by-step explanation:

Given

Percentage of tax = 7%

Also given that the amount of tax is $1.40

Let x be the price of meal

Then the tax will be 7% of x

It can be written mathematically as:

[tex]1.40 = 7\%\ of\ x[/tex]

We will simply solve this equation to get the price of meal

So,

[tex]1.40 = 0.07*x\\x = \frac{1.40}{0.07}\\x = 20[/tex]

Hence,

The cost of meal is: $20

Step-by-step explanation:

The general form of a straight line is y = mx + c, where m is the line's slope and c is the y-intercept.

For y = 3x + 2, the slope is positive 3 and the y-intercept is 2. The line should rise up and pass through the point (0, 2).

We are between Options B and C.

In Graph B, the line raises by 4 units for every 2 units across. Hence its slope is 4/2 = 2.

In Graph C, the line raises by 3 units for every 1 unit across. Hence its slope is 3/1 = 3.

Since we want 3 as the slope,

The answer is Option C.

The graph C represents y=3x+2​

Step-by-step explanation:

Answer:

All the options are equivalent except;

4 + y

Step-by-step explanation:

The question relates to the number of ways the operation of a multiplication operation can be represented algebra

1) The coefficient of a variable is a multiplier of the variable

Therefore;

4y = 4 × y

2) When given two numbers or variables in a mathematical expression that are separated by parenthesis, then it is an indication that the two numbers are meant to be multiplied

Therefore;

(4)(y) = 4 × y

3) The dot symbol, '·', placed between two numbers, a number and a variable or two variables, is a representation of multiplication of the two quantities

Therefore;

4·y = 4 × y

However, multiplication, and addition are different mathematical operations that produce different results when applied;

Therefore;

4 + y ≠ 4 × y.

Answer:

300,000 liters

Step-by-step explanation:

Let us have the measurements in cm

100 cm = 1 m

so the measurements are multiplied by 100

we have this as;

1500 by 1000 by 200

The volume is the product of the 3

This is :

1500 * 1000 * 200 = 300,000,000 cm^3

Mathematically, 1 liter = 1000 cm^3

300,000,000 cm^3 will be ;

300,000,000/1000 = 300,000 liters

Answer:

Look at the picture attached.

Step-by-step explanation:

Your x-intercept is 6 and your y-intercept is 4, that is where your 2 points will go. According to the slope, you should go up 2 and over 3, if you don't want to find the x-intercept. Then you would just plot the y-intercept which is 4, and then go up 2, over three and plot the next.

Answer:

300 km in hour are the answers

Answer: D. 453 miles .

Step-by-step explanation:

Given: The function [tex]d(t)=458-60t[/tex] models the distance, in miles, that Jessica is from her house t hours after she began returning home.

At t = 5 minutes = [tex]\dfrac{5}{60}[/tex] hour     [1 hour = 60 minutes],

Distance covered by Jessica in 5 minutes = [tex]d(\dfrac{5}{60})=458-60(\dfrac{5}{60})[/tex]

[tex]=458-5=453\ miles[/tex]

Jessica is 453 miles from her home after 5 minutes she began returning home.

Hence, the correct option is D. 453 miles .

Answer:

$58.64

Step-by-step explanation:

The total cost of a game g with 7% sales tax can be represented by the expression

g + 0.07g

From the above question,

g = Original price of the game = $52.

The total cost of game g =

$52 + 0.07 × $52

$52 + $3.64

= $58.64

Answer:

The jet will cover 2585 miles in 11 hours.

Step-by-step explanation:

Given that:

Distance travelled by jet in 2 hours = 470 miles

Speed of jet = [tex]\frac{Distance}{Time}[/tex]

Speed of jet = 470/2

Speed of jet = 235 miles per hour

Time = 11 hours

Distance travelled in 11 hours = Speed * Time

Distance = 235 * 11

Distance = 2585 miles

Hence,

The jet will cover 2585 miles in 11 hours.

So if you solve for x using the first equation, you get: x = 5y - 5.

From there you can plug that into the second equation which would give you:

7y-5y+5=-23

Simplifying from that point, you get y = -9.

Now that you have one of the values, you can solve for x by plugging it back into the equation we made (x = 5y - 5) and getting to the answer x = -40.

Answer: The answer is 0.20

Step-by-step explanation:  To find a scale factor all you need to do is find the ratio of a side on the scaled shape to its corresponding side on the original figure.  We know the bottom of the scaled figure is 0.5 and the same side on the original rectangle was 2.5 so we can just divide like so...

0.5/2.5 = 0.2 which is our correct answer.  I hope this has been of use to you :)  If you have any other questions please do not hesitate to ask!
