700% of what number is 1,540?

Answer:

84 points

y= 100-2x where y= total score (0 through 100) and x= # of questions wrong (0 through 50)

Step-by-step explanation:

100- 2(8) = y

100-16 = y

84=y

Since each question (x) is worth two points (2) we have to multiply each wrong question by two (2x). And then since we're deducting point from the possible points (100) we have to subtract (100-2x)

Answer:

The median is 5cm.

Step-by-step explanation:

Median is one of the 3 famous measures of central tendency.

The others are: mean & mode.

A median is the middle figure in an array of figures which are lined up from lowest value to highest value.

Here, the variable we're working with is Amount of rainfall in Vietnam cities (in centimeters).

The data shows   4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm, 0cm, 1cm, 2cm, 3cm

We start by arranging them in order of value; from lowest to highest:

0cm, 1cm, 2cm, 3cm, 4cm, 5cm, 6cm, 7cm, 8cm, 9cm, 10cm

There are 11 values in total.

Since 11 is an odd number, it is easy to find the median in this set of values.

Five values to the left and five values to the right; the median is 5cm!

Answer:

A number is odd

Step-by-step explanation:

Odd numbers are not completely divisible by 2.

The importance of knowing divisibility rules is that we can determine whether a number is divisible by certain numbers generally from 1 to 20 or not without actually dividing.

A number is divisible by 2 if it's unit digit is divisible by 2.

A number is divisible by 3 if the sum of the digits is divisible by 3.

A number is divisible by 4 if the last two digits is divisible by 4.

A number is divisible by 5 if its unit digit is 5 or 0.

A number is divisible by 9 if the sum of the digits is divisible by 9.

A number is divisible by 10 if its unit digit is 0.

Given, If a number is odd, then it has a remainder of 1 when divided by 2.

So the numbers which are not completely divisible by 2 have a remainder and are odd numbers and numbers which are completely divisible by 2 with no remainder are even numbers.

Step-by-step explanation: The keyword is hourly. Since the keyword is hourly, the equation is division.

72 / 4

1. 4 goes into 7 once.

1a. 72 / 4 = 1

2. Now we multiply 4 by 1.

2a. 4 x 1 = 4

3. Now, we subtract 7 by 4.

3a. 7 - 4 = 3

4. Now bring down the 2.

4a. 3 = 32

5. Then you repeat the process!

We'll do the last one step-by-step!

1. 2 goes into 4, 8 times.

1a. 72 / 4 = 18

2. Multiply 8 by 4.

2a. 8 x 4 = 32

3. Lastly, subtract 32 by 32.

32 - 32 = 0

Therefore, your answer is 18 R0.

Answer:

Exponential growth of 7%

Step-by-step explanation:

We are given the function:

A function is shown: f(x) = (1.07)^x

We can compare this to a formula of Exponential Growth

y = a(1 + r)^x

Hence:

1 + r = 1.07

r = 1.07 - 1

r = 0.07

Converting to percy

0.07 × 100

= 7%

Therefore, the function represents Exponential growth of 7%

Answer:

The speed of the motorcycle is 66 miles per hour.

Step-by-step explanation:

We use the following relation to build a system of equations.

[tex]v = \frac{d}{t}[/tex]

In which v is the velocity, d is the distance, and t is the time.

Car:

[tex]v_{c} = \frac{d_{c}}{t}[/tex]

We have that the car travels 90 miles, so [tex]d_c = 90[/tex]

Then

[tex]v_{c} = \frac{90}{t}[/tex]

[tex]t = \frac{90}{v_{c}}[/tex]

a motorcycle travels 6 mph faster than a sport car.

This means that [tex]v_m = 6 + v_{c}[/tex], so [tex]v_{c} = v_m - 6[/tex]

Travels 99 miles, so [tex]d_m = 99[/tex]

[tex]v_{m} = \frac{99}{t}[/tex]

Since [tex]t = \frac{90}{v_{c}}[/tex] and [tex]v_{c} = v_m - 6[/tex], we have that [tex]t = \frac{90}{v_{m} - 6}[/tex]

So

[tex]v_{c} = \frac{99}{t}[/tex]

[tex]v_{m} = \frac{99}{\frac{90}{v_{m} - 6}}[/tex]

[tex]v_m = \frac{99(v_{m} - 6)}{90}[/tex]

[tex]99(v_{m} - 6) = 90v_m[/tex]

[tex]99v_m - 594 = 90v_m[/tex]

[tex]9v_m = 594[/tex]

[tex]v_m = \frac{594}{9}[/tex]

[tex]v_m = 66[/tex]

The speed of the motorcycle is 66 miles per hour.

Answer:

x = -24/5

Step-by-step explanation:

1/4x=-5/6

as 4 is multiplied to x on the left hand side, if we shift 1/4 to the right hand side the equation becomes:

6/-5=4x

now the 4 multiplied to x moves to the left hand side:

(6/-5)x4 =x

x = -24/5

Answer:

Step-by-step explanation:

Formula for continuous compounding is;

Total amount after the compounding period = P + P[(e^(rt)) - 1]

Where;

P = principal

r is interest rate

t is time period of compounding

We are given;

P = $12,000

Interest rate; r = 7.5% = 0.075

Time; t =?

Amount after investment; $23,568.40

Thus;

23568.40 = 12000(1 + [(e^(0.075t)) - 1])

(1 + [(e^(0.075t)) - 1]) = 23568.40/12000

[(e^(0.075t)) - 1] = (23568.40/12000) - 1

[(e^(0.075t)) - 1] = 0.964

(e^(0.075t)) = 1 + 0.964

(e^(0.075t)) = 1.964

0.075t = In 1.964

0.075t = 0.67498

t = 0.67498/0.075

t = 9 years

The answer is y = 3/5x + 2

Equation of the line that goes through the points (-5, -1) and (5, 5) is y =   [tex]\frac{3}{5}[/tex] x + 2.

Slope of a line is defined as the tangent of the angle that the given line is making with the X axis.

Slope of a line is usually denoted by the letter 'm'.

m = tan θ, where θ is the angle.

Slope of a line passing through the points (x1, y1) and (x2, y2) is,

m = (y2 - y1) / (x2 - x1)

Here we have two points (-5, -1) and (5, 5)

m = (5 - -1) / (5 - -5) = 6 / 10 = 3/5

Equation of a line in point slope form is,

y - y₁ = m (x - x₁), where (x₁, y₁) is a point on the line.

We take a point (5, 5)

y - 5 = [tex]\frac{3}{5}[/tex] ( x - 5)

y - 5 =  [tex]\frac{3}{5}[/tex] (x) -  [tex]\frac{3}{5}[/tex] (5)

y - 5 =   [tex]\frac{3}{5}[/tex] (x) - 3

y =   [tex]\frac{3}{5}[/tex] x - 3 + 5

y =   [tex]\frac{3}{5}[/tex] x + 2

Hence the equation of the line passing through the points (-5, -1) and (5, 5) is y =   [tex]\frac{3}{5}[/tex] x + 2.
