The different ways that are there of selecting the trucks and the drivers to meet these requests is 240 ways.

Combinations are also referred to as selections. Combinations imply the selection of things from a given set of things. In this case, we intend to select the objects.

Combination formula

ⁿCr = n! / ((n – r)! r!)

n = the number of items.

r = how many items are taken at a time.

The number of ways to select 3 trucks will be:

= ⁵C₃ = 10

The number of ways to select 3 drivers will be:

= ⁴C₃ = 4

Number of ways to arrange them = 3! = 3 × 2 = 6

Therefore the total number of ways will be:

= 10 × 4 × 6

= 240 ways

Oliver is left with $514.8

A percentage is a number or ratio expressed as a fraction of one hundred. If we need to calculate a percentage of a number, divide it by the whole and multiply by 100. As a result, the percentage represents one part in a hundred. The term % stands for one hundred percent.

His usual salary = $520 per week

This week he earned = Usual salary + 10% of usual salary

10% of usual salary =520 x (10/100)  

Thus, this week's earnings = $520 + $52 = $572

Amount spent = 10% of this week =572 x (10/100)    

= 57.2

Thus, the left amount is calculated by:

Left amount = this week's salary - the amount spent

Amount left  = $572 - $57.2 = $514.8

Thus, Oliver is left with $514.8

Step-by-step explanation:

8 houses are done in 4 minutes

The ratio is 2:1

20 houses are done in 10 minutes
20:10 = 2:1

Answer:

It would take Angelo 10 minutes to construct 20 playing card houses.

first way to solve it (recommended):

Step one: See how much it takes to build one house

4 / 8 = 0.5

0.5 minutes to build one house

Step two: multiply by amount of houses (20)

0.5 x 20

Step three: get your answer!

It would take Angelo 10 minutes to make 20 houses.

second way to solve it (ratios):

Step one: see the ratio of minutes to houses

minutes : houses

          4 : 8

Step two: simplify the ratio

4 : 8

1 : 2 (divide both sides by four)

Step three: multiply

x minutes : 20 houses

1 minutes : 2 houses

multiply both sides by 10

10 minutes : 20 houses

Step four: get your answer!

It would take Angelo 10 minutes to make 20 houses.

The linear equation shown in the graph is the one in the third option.

y + 2 = -3*(x - 1)

Here we have a graph, and there we can see a linear equation, on that graph, we can see that:

The y-intercept is y = 1.

For each horizontal unit, the line goes 3 units down, then the slope is -3.

Then the linear equation is:

y = -3*x + 1

If now we add 2 in both sides, we get:

y + 2 = -3x +1 + 2

y + 2 = -3x + 3

y + 2 = -3*(x - 1)

So the correct option is the third one.

The value of the coin after five years is 535 when the value increases with the function f(x) = 100(1.07)x

The value of a rare coin rises in accordance with the function f(x)

f(x) = 100(1.07)x

where x represents the number of years that the coin is owned and value is measured in US dollars

Now, Simplifying the given function, we have :

f(x) = 100(1.07)x

f(x) = 107x

Now, we need to find the value of the coin after five years, then

Putting x = 5 in the function,

f(x) = 107 * 5 = 535

Hence, the value of the coin after five years is 535 when the value increases with the function f(x) = 100(1.07)x

A ratio is dividing.

This means that numerous ratios can be used, to the point where the answers are infinite.

The equation of the line has a slope of 7 and passes through the point (-8,3) is y = 7x + 59.

A straight line on the coordinate plane is represented by a linear function.

A linear function always has the same and constant slope.

The formula for a linear function is f(x) = ax + b, where a and b are real values

The general form of a linear equation is the slope(m) and y-intercept (c) is given as

y = mx + c

Slope m =7

y = 7x + c

Substitute, (-8,3)

3 = 7(-8) + c

c = 59

Thus, y = 7x + 59 will be the equation.

Hence "The equation of the line has a slope of 7 and passes through the point (-8,3) is y = 7x + 59".

The numbers of ladies and gentlemen in the club are 2 and 18 respectively.

The percentage is a ratio that can be expressed as a fraction of 100

Given that, there are 90% of ladies in the club, and the number of ladies is 12 more than 3 times the number of gentlemen.

Let the number of gentlemen is x and the number of ladies be y.

Since the number of ladies is 12 more than 3 times the number of gentlemen, it follows:

y  = 12 + 3x     (1)

Now, the total number of members in the club is:

x + y

Since there are 90% ladies in the club, it follows:

90%(x + y) = y

90(x + y)/100 = y

90x + 90y = 100y

90x = 100y - 90y

90x = 10y

9x = y             (2)

Now, substitute y = 9x into equation (1):

9x = 12 + 3x

9x -3x = 12

6x = 12

x = 2

Substitute x = 2 into equation (2):

9(2) = y

18 = y

Hence, the numbers of ladies and gentlemen in the club are 2 and 18 respectively.

Answer:

Step-by-step explanation:

Adding 5 m to the width of a rectangle makes it a square with area 144 m². You want the length and width of the original rectangle.

The formula for the area of a square is ...

  A = s²

The side length of the square formed from the rectangle is ...

  144 = s²

  √144 = s = 12 . . . . . meters

The length of the rectangle is unchanged when it is made into the square, so the length is 12 m.

The width of the rectangle had 5 m added to make it 12 m, so the width of the rectangle is 7 m.

__

Additional comment

The given relation between length and width is given as L = 2W -2. It is true that 12 = 2(7) -2, but that is not needed in order to solve this problem. It does serve as a check on our answer.

The height is 17.69 inches.

From the question, we have

Let height= h

width = h+4

diagonal = 28 inches

Using Pythagoras Theorem

28²  = h²  + (h+4)²

784 = h² +h² +16+8h

784  = 2h² +16+8h

2h²+8h-768 = 0

Solving this, we get

h=−2+2*√97

h=17.69 inches

Multiplication:

Finding the product of two or more numbers in mathematics is done by multiplying the numbers. It is one of the fundamental operations in mathematics that we perform on a daily basis. Multiplication tables are the main use that is obvious. In mathematics, the repeated addition of one number in relation to another is represented by the multiplication of two numbers. These figures can be fractions, integers, whole numbers, natural numbers, etc. When m is multiplied by n, either m is added to itself 'n' times or the other way around.

It follows from the task content that the set of side lengths which will not create a triangle are to be determined from the given task content.

Since the triangle inequality theorem states that; the sum of two side lengths of a triangle is always greater than the third side length and also, the difference of two side lengths of a triangle is less than the third side length.

On this note, for a triangle with side-lengths a, b and c; the inequalities which hold are;

a + b > c and a - b < c.

Therefore, the set of side-lengths which will not create a triangle is; 10, 20, 30.

Answer:

x=3

Step-by-step explanation:

any horizontal line is equal to x

the y is equal to 0

a horizontal line is undefined

Answer: y=3x

Step-by-step explanation:

The equation can be found by finding the slope of the given line. Visually, this can be found by counting the distance between two points. From (1,3) and (2,6), the line "rises" 3 units and "runs" 1 unit to the right. Since slope is calculated as rise over run, this gives us 3/1, or just 3 for slope. In slope-intercept form, this becomes y=3x.

Just to note, we know it is not negative because of the direction of the slope. Visually, if the slope "moves" in the direction of upwards and to the left, it will be positive. This can be calculated more accurately using the slope formula (y2-y1/x2-x1)
