Answer:

2:5

Step-by-step explanation:

6:15= 2:5

By rewritting the 6 as 5 + 1 we will get:

1 + 5 + 5 = 1 + (5 + 5) = 11

One trick we do a lot when we do additions os making tens (or hundreds, thousands, etc... depending on the case).

This means that we play with the numbers in such a way that we can make tens, in this case we have the sum:

6 + 5

We can rewrite this as:

6 + 5 = 1 + 5 + 5

Using the associative property we rewrite:

1 + 5 + 5 = 1 + (5 + 5)

1 + (5 + 5) = 1 + 10 = 11

The sum is equal to 11.

When using the standard algorithm to find the product 5,917x29, the first step is multiplying 9 ones by 7 ones, it's important to regroup in order to correctly multiply the values.

Using partial products or multiplying in parts is how the conventional method does multiplication. A word that also signifies multiplication is "product," so keep that in mind. Any two numbers, regardless of how tiny or how large, can be multiplied using this standard technique.

The top number is multiplied by the bottom number, one digit at a time, working your way from right to left, using this procedure.

The graph of the linear equation:

y = -3x + 4

Can be seen in the image at the end.

Here we know that the equation for the line is:

y = k*x + 4

We know that this line goes through the point (2, -2), then we can replace these values in the above line so we get the value of k.

-2 = k*2 + 4

With this, we can find the value of k.

-2 - 4 = k*2

-6 = k*2

-6/2 = k = -3

Then the line is:

y = -3*x + 4

If we evaluate in x = 0, we get:

y = -3*0 + 4 = 4

So, at this point we know that the line passes through points (0, 4) and (2, -2), so to graph the line, we just need to graph these two points and draw a line that connects them, like in the example below.

Considering the expression of a line, the statements:

about the line that passes through (-2, 0) and (2, -4) are true.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂) of a line, the slope m of said line can be calculated using the following expression:

m= (y₂ - y₁)÷(x₂ - x₁)

Substituting the value of the slope m and the value of one of the points in the expression of a linear equation, y = mx + b, the value of the ordinate to the origin b can be obtained.

Being (x₁, y₁)= (-2, 0) and (x₂, y₂)= (2, -4), the slope m can be calculated as:

m= (-4 - 0)÷(2 - (-2))

m= (-4)÷ 4

m= -1

Considering point 1 and the slope m, you obtain:

0= -1×(-2) + b

0= 2 +b

-2= b

Finally, the equation of the line that passes through the pair of points (-2,0) and (2,-4) is y= -x -2, wich has a slope of -1. The line intersects the x-axis at (−2, 0).

If x=0, you get:

0= -x -2

2= -x

The area in square units of the hexagon will be 12√3.

What is Hexagon?

A polygon with six sides are called a hexagon.

Given that;

Jennifer makes a hexagon by arranging 6 equilateral triangles.

The length of one side of a triangle is 4.

Now, To find the area of hexagon, we find the height of the equilateral triangle and then multiply by the 6.

So, In ΔABC;

AB = BC = CA = 4

Then, Measure of DC = BD = 2

Now, using Pythagoras theorem to find height of triangle (AD) as;

AD² = AC² - DC²

AD² = 4² - 2²

AD² = 16 - 4

AD² = 12

Take square root both side;

AD = √12

AD = 2√3

So, The area of hexagon = 6 × Height of triangle

                                      = 6 × 2√3

                                      = 12√3

Thus, The area in square units of the hexagon will be 12√3.

From the attached question, we have the following parameters

P(White Vehicle) = 0.25

P(Car) = 0.36

P(White Car) = 0.08

Using the complement rule of probability, we have the following equation

P(White Car) + P(Not White Car)  = 1

Substitute the known values in the above equation

So, we have the following equation

0.08 + P(Not White Car)  = 1

Subtract 0.08 from both sides of the equation

So, we have

P(Not White Car)  = 1 - 0.08

Evaluate the difference

P(Not White Car)  = 0.92

The unit rate he can drive in mile per gallon is 22 miles per gallon.

Unit rate can be defined as the ratio between two measurements with the second term as 1.

In other words, a unit rate describes the ratio of two different units for the quantity of one.

Therefore, the  unit rate in miles per gallon can be calculated as follows:

Hence,

unit rate = number of miles / number of gallons

number of miles = 330 miles

What is Probability ?

The area of mathematics known as probability deals with numerical representations of the likelihood that an event will occur or that a statement is true. An event's probability is a number between 0 and 1, where, roughly speaking, 0 denotes the event's impossibility and 1 denotes certainty.

Given,

P(A) = 0.2,

P(B) = 0.31 and

P(A/B) = 0.152,

Since, we know that

P(A⋃B) = P(A)+P(B)-P(A⋂B)

So, we have to find P(A⋂B)

We know that,

P(A/B) = P(A⋂B)/P(B)

Putting the values we get,

0.152 = P(A⋂B) / 0.31

P(A⋂B) = 0.152 x 0.31

P(A⋂B) = 0.047

Now, lets find the value of P(A⋃B)

P(A⋃B) = P(A)+P(B)-P(A⋂B)

Putting the values we get,

P(A⋃B) = 0.2 + 0.31 + 0.047

P(A⋃B) = 0.557

Hence the value of P(A⋃B) = 0.557

Jack's percentage decrease on his measurement of painting by 18%.

What is meant by percentage change?

Measures of percent change include percent increase and percent decease, which indicate how much an element of a variable changes in terms of intensity, size, extent, or value.

Given that,

Jack's measurement for his room =  5 ft (taking this as old value)

Actual measurement for Jack's room = 4.1 ft (taking this as new value)

Using formula for Percent change =  [tex]\frac{new - old}{old}[/tex]  × 100% =  [tex]\frac{4.1 - 5}{5}[/tex] × 100%

                                                       =  [tex]\frac{-0.9}{5}[/tex] × 100% = -0.18 × 100%

                                                       = -18%

Row 2: There are 2 spiral shapes and 2 rectangle shape.

2C + 2D = 16 ......( equation 2)

Row 3: There are 1 star, one pentagon and 2 rectangle shape.

A + B + 2D = 24 ....(equation 3)

Row 4: There are 3 spiral shapes and one star shape.

B + 3C = 15 ....(equation 4)

Column 1:

2C + A + D = 19 ....(equation 5)

Column 2:

2B + C + D = 20 .....(equation 6)

From equation 4;

B = 15 - 3C

From equation 2:

D = 8 - C

A + 2B + C = 23

A + 2(15 - 3C) + C = 23

A + 30 - 6C + C = 23

A = 5C - 7

2C + A + D = 19

2C + (5C - 7) + 8 - C = 19

6C + 1 = 19

6C = 18

C = 3

A = 5C - 7

A = 5(3) - 7

A = 8

B = 15 - 3C

B = 15 - 3(3)

B = 6

D = 8 - C

The interest paid on the loan and the total amount paid are $84,320 and $152,320 respectively.

It is given in the question that:-

Money borrowed by the company (Principal) = $68,000

Time period for which the money is borrowed = 8 years

Simple Interest rate = 15.5 %

We have to find the interest paid on the loan and the total amount paid.

We know that,

Simple interest = (Principal * Interest * Rate)/100

Hence, we can write,

Simple interest = (68000 * 15.5 * 8)/100 = $84,320

The number of iPhones that should be sold in 2017 (since growth is exponential) is $ 6,476,635 x 10⁶. See the explanation below.

Exponential growth is a data pattern that exhibits greater increases with time. Compounding produces exponential profits in finance. Compounding interest savings accounts may provide exponential growth.

The calculation for the above solution is as follows:

Recall that the formula for exponential growth is:

f(x) = a (1+r)ˣ

Where:

f(x) = exponential growth function

a = initial amount

r = growth rate

{x} = number of time intervals

Hence f(x) = 1.7 (1+ r)⁵

Note that x = 2017-2012 =5

r = (present value - past value)/ past value

Present value = 35.2

Past Value = 1.7

Hence r = (35.2-1.7)/1.7

r = 19.7058823529

Approximately 19.71

Hence,

f(x) = 1.7 (1+ 19.71)⁵

= 1.7 (20.71)⁵

= 1.7 x 3809785.2361

= 6476634.90137
