Answers

Answer:

12.72 m

Step-by-step explanation:

You're going to use the left side from the middle of AD up to point A. You see that's the same as a radius, so its length is 4.5. Then you can use the Pythagorean theorem to find the hypotenuse, the blue line from X to A.

(4.5)^2+(4.5)^2=x^2

40.5=x^2

x=6.36

and AC is two of the line you just figured out so 6.36x2=12.72m

What is a system of equations?

A system of equations is two or more equations that can be solved to get a unique solution. the power of the equation must be in one degree.

Given; Malik uses an app on his phone to track how far he rides his bike. Yesterday, he biked a new trail in a total of 57.5 minutes, including a 2.5-minute water break. The app notified Malik that he rode 10 miles.

Now, This equation represents the situation.

Now, solve the equation for p;

10p+2.5 = 57.5

Subtract 2.5 from both sides;

10p = 55

Divide both sides by 10

p = 5.5

Therefore, Malik's average pace was 5.5 minutes per mile.

the yellow T-shirt cost as the blue T-shirt?
Draw a bar diagram and write and solve
an equation.

Yellow shirt $24
Blue shirt $8

Answers

The bar diagram is attached below. As we can see, the price of a yellow T-shirt is as three times as the price of a blue T-shirt. Hence, we can construct the following equation to determine the ratio between both prices:

[tex]y = r\cdot x[/tex] (1)

Where:

[tex]x[/tex] - Price of blue T-shirt, in monetary units.[tex]y[/tex] - Price of the yellow T-shirt, in monetary units.[tex]r[/tex] - Price ratio, no unit.

If we know that [tex]x = 8[/tex] and [tex]y = 24[/tex], then the price ratio is:

[tex]r = \frac{y}{x}[/tex]

[tex]r = 3[/tex]

The price of the yellow T-shirt is as three times as the price of the blue T-shirt.

Two sides of a triangle are 11 can and 14 cm what are all the possible values for the length of the third side

Answers

Answer:

Step-by-step explanation:

The third side is thus, less than 14 + 11 = 25 cm. The side cannot be less than the difference of the two sides. Thus, the third side has to be more than 14 - 11 = 3 cm. So, the length of the third side could be any length greater than 3 cm and less than 25 cm.

Juanita borrowed $600 to purchase a new computer. She was charged 7% interest for two years. She used the simple interest formula to find the interest.

I = 600(7)(2)

What error did Juanita make and how will her error affect the interest she calculates? Explain.

please help

Answers

Answer:

The error she made was multiplyng by 7. This would affect her calculations as 7 in percentage form is represented as 700%. The 700% interest would basically mean she owes 7 times the amount she borrowed. The correct number would be 0.07 because 0.07 represents 7% which is the interest. Another error that was made was multiplying 2 to the entire equation. The only thing that needs to be doubled is the interest as every year the interest takes 7%. The correct way would be to put 0.07*2 in paranthesis. The correct equation is

I = 600(0.07*2)

Juanita did not convert the interest rate into its decimal form. The interest rate used for solving the simple interest should have been 0.07. She could have moved the decimal point two places to the left, or divide 7/100-- either way, the conversion would have resulted to 0.07.

Her original solution will produce an interest of: I = $600(7)(2) = $8,400

In comparison, using 0.07 for the interest rate will result in an interest amount of:

I = $600(0.07)(2) = $84.

The product of 0.4 and a number is 8.

(a) Represent the statement as an equation. Use n for the variable.
(b) Determine the solution set using the replacement set .

Answer:

Answers

20 is a solution to the equation by using the replacement set.

Let the unknown variable be n.

Given the following data:

Output = 8

a. To represent the statement as an algebraic equation:

In this exercise, you're required to write a mathematical expression (algebraic equation) that represents the word sentence given.

Translating the word sentence into an algebraic expression, we have;

The product of 0.4 and a number is 8:

[tex]0.4n = 8[/tex]

b. To determine the solution set using the replacement set:

Let's use the following set of numbers (0, 1, 10, 20)

When n = 0:

[tex]0.4(0)=8\\\\0\neq 8[/tex]

When n = 1:

[tex]0.4(1)=8\\\\0.4\neq 8[/tex]

When n = 10:

[tex]0.4(10)=8\\\\4\neq 8[/tex]

When n = 20:

[tex]0.4(20)=8\\\\8= 8[/tex]

Therefore, 20 is a solution to the equation by using the replacement set.

Let y be a function of x such that 2x - 3y = 6. What is the rate of change of y with respect to x?

Given the equation 2x -3y= 6

since we are to find the rate of change of y with respect to x we make y subject of formula

2x -3y= 6

Find the next number in the pattern: 12, 24, 48, 96, ...

Answers

Answer:

196

Step-by-step explanation:

12, 24, 48, 96, __?

The next term will come by multiplying with number 2

12 *2 = 24,

24*2 = 48,

48*2 = 96,

96*2 = 192,

& The answer will be 196

Answer:

Each time the pervious number is being doubled (multiplied by 2). So the next number would be 96 x 2. So, the next number on the pattern is 192.

Find the gradient of the line segment between the points (4,6) and (8,14).

Answers

Let a = (x1,y1) = (4,6) and b = (x2,y2) = (8,14)

Then, since the formula of the gradient (or Slope), given two points a and b is :

m = (y2 - y1) / (x2-x1) = (14 - 6) / (8 - 4) = 8 / 4 = 2

Then we know that the gradient is m = 2
