Multiplication is the method that is used to add a number by itself a particular number of times. The sign used to denote multiplication is x. Other mathematical operations are subtraction, division and addition.

In order to determine the total amount spent on gas, multiply the cost of one gallon by the number of hours skied and the amount of galloons used per hour.

The total amount spent on gas = cost of one gallon of gas x number of hours skied x number of gallons used per hour

Answer:

128.52

Step-by-step explanation:

140 × (1-0.15) = 119

119 × 1.08 = 128.52

Answer:

$128.52

Step-by-step explanation:

Firstly to find the price of the scooter, you divide 140 by 100 and then multiply it by 15. The answer is what you subtract from the original price.

15(140/100) = 21

140 - 21 = 119

Now that we have the price of the scooter after the discount, we need to figure out the price of the sales tax. Sales tax is based on the reduced price, so we need to take the same steps as before to find the price. Divide 119 by 100, then multiply it by 8, then add the total to 119.

8(119/100) = 9.52

119 + 9.52 = 128.52

Answer = $128.52

2(I) We round a number to three significant figures in the same way that we would round to three decimal places. We count from the first non-zero digit for three digits. We then round the last digit. We fill in any remaining places to the right of the decimal point with zeros.

8348 = 8350(rounded to 3 SF)

2(ii) 0.00796 = 0.0080

2(II) 6.329 = 6

2(III) 0.05684 = 0.0568

Step-by-step explanation:

1.i

2a^-1 × 3a²

remember, when we multiply factors with the same base value or variable, we keep that base value or variable and simply add the exponents.

-1 + 2 = 1

so, we get

2×3 × a¹ = 6a

1.ii

(1/2)^-3

remember, the "-" on the exponent just means 1/...

so, it is actually

1 / (1/2)³ = 1 / 1/8 = 8

1.iii

2a^-1 × (3a)²

similar to the first one, but remember, when we put the product of factors to a certain power, we need to do this for every factor of the inner multiplication :

2a^-1 × 9a² = 2×9 × a¹ = 18a

2.

the first significant figure is the first digit in the number reading from the left, that is not 0. it can be before or after the decimal point.

any digit (now continuing to read further to the right) after the first significant figure is again a significant figure even if it is 0.

i.

8.348 is rounded to 3 significant figures : 8.35

ii.

0.00796 is rounded to 2 significant figures :

0.0080 or 0.008 (because if the last digit after the decimal point is a 0, we can ignore it).

iii.

6.329 is rounded to 1 decimal place : 6.3

iv.

0.05684 is rounded to 3 decimal places : 0.057

3.

the sum of interior angles in a polygon is (n − 2) × 180°. where n is the number of sides.

as deca stands for 10, a decagon has 10 sides and 10 vertexes.

the sum of its inner angles is

(10 - 2) × 180° = 8 × 180° = 1440°

1170° of that is already covered by the first 7 angles.

so, we have left

1440 - 1170 = 270°

for the remaining 3 angles (that are all equal).

so,

270 = 3×angle

angle = 270/3 = 90°.

so, all of the 3 remaining angles are 90°.

Step-by-step explanation:

The slope of the line that passes through the given points (2, 12) and (6, 11) is -1/4.

The graph that represents the inequality is graph b

From the question, we are to graph the given inequality

The given inequality is

y ≥ |x+5|-3

To graph the inequality, we will write the inequality as an equation and we will find some of the points on the line

When x = 0

y = |x+5|-3

y = |0+5|-3

y = |-3

When y = 0

y = |x+5|-3

0 = |x+5|-3

0 = (x + 5) - 3 and 0 = -(x + 5) -3

3 = x + 5

x = 3- 5

x = -2

and

0 = -(x + 5) -3

x + 5 = -3

x = -3 - 5

x = -8

The graphs that has the points above are graphs b and d.

Since the inequality sign is ≥ when y is the subject, the solution to the inequality is above the lines.

Hence, the graph of the inequality is graph b.

The domain of the function is -∝ < x < ∝, the range of the function is -∝ < y < ∝, and the x-intercept of the function is (-1, 0)

The equation of the function is given as

g(x) = 4x + 4

The function g(x) is a linear function.

There is no restriction on the input values and output values of a linear function

This means that the domain and the range of a linear function are the set of all real numbers

Set g(x) to 0, to determine the x-intercept

So, we have

4x + 4 = 0

Divide through by 1

So, we have

x + 1 = 0

Evaluate the like terms

x = -1

Hence, the domain of the function is -∝ < x < ∝, the range of the function is -∝ < y < ∝, and the x-intercept of the function is (-1, 0)

so you write 16 but i don't speak English very good i want help you 2(6+3)-2 ok you you going multiplying 2×6=12+6=18-2=16 so 16

Answer:

See the picture below

Step-by-step explanation:

Your equations are in the slope-intercept form of a line.  The equations are make up of a slope and a y-intercept.

y = mx + b  The m is the slope (the steepness of the line) and b is the y-intercept.  This is where the line crosses the y axis.

I would start with the y intercept.  Look at the first equation

y = x -8  The -8 tells us that this graph crosses the y axis at (0,-8)  From that point, we will use the slope.  The slope is the number before the x.  If we do not see a number than it is 1.  We want to make this a fraction. What is 1 as a fraction?  1/1  This means that from -8 where the graph crosses the y axis we will follow the pattern of up one, one to the right.

Let's look at the second graph

y = -x + 5.  This tells us that we cross the y axis at (0,5).  Our slope is -1.  What is -1 as a fraction?  -1/1.  This means that we will move down 1 and right one.  We will follow that pattern.

Let's look at the third graph

y = 3/4x - 1  We cross the y axis at (0,-1)  From that point we move up 3 and right 4.

y = 3 means that no matter what x is, y will be -3.  This creates a horizontal line.

x = -4 means that not matter what y is, x will be -4.  This creates a vertical line.

The required equivalent expression would be 3¹² y¹⁰ which is the correct option (C).

An exponential function is defined as a function whose value is a constant raised to the power of an argument is called an exponential function.

It is a relation of the form y = aˣ  in mathematics, where x is the independent variable.

We have been given that exponential function as

⇒ (3⁶/y⁻⁵)²

= (3⁶/1 / 1/y⁵)²

= (3⁶ × y⁵)²

= 3¹² y¹⁰

Therefore, the required equivalent expression would be 3¹² y¹⁰ which is the correct option (C).
