The required measure of the hypotenuse length is √544. Option D is correct.

In a right triangle, the length of one leg is 20 units. The length of the other leg is 12 units.

In a right-angled triangle, its side, such as hypotenuse, perpendicular, and base is Pythagorean triplets.

Here,
Apply Pythagoras' theorem,
(hypotenuse)² = sum of the square of the legs,
(hypotenuse)² = 20² + 12²
(hypotenuse)²  = 544
hypotenuse = √544

Thus, the required measure of the hypotenuse length is √544. Option D is correct.

Answer: 54.2%

Step-by-step explanation:

The percent mark-up refers to how much higher you sell a product than what you bought it for expressed as a percentage of what you bought it for.

In this case, the woman bought it for $120 and sold it for $65 more.

Cost = $120

Markup = $65

Markup percentage = 65 / 120 * 100%

= 54.2%

Answer:

A.

The y intercept is at 0,550 for the city of Everett. That means that initially the city started out with 550 Chromebooks.

B. y = 50x + 300

Step-by-step explanation:

A.

The y intercept is at 0,550 for the city of Everett. That means that initially the city started out with 550 Chromebooks.

For all the years after is when the line graph goes up which means they are adding to their total number.

B.   For the city of Revere, they started out with 300 and are adding 50 Chromebooks every year.

Y represents the total and x is each counting year.

So the equation of the line is represented by y = mx + b

b is any constant which in this case is any initial amount (300)

and m is the rate/change which is the number represented by the value that will go up ever year of x (50)

So plug it all in equals:

y = 50x + 300

Answer:

ANSWER

y = 3x + 6.50

EXPLANATION

The $3 for each downloaded movie is the unit rate of change.

This is represent the slope of the linear function that models this situation.

The monthly fee of monthly fee of $6.50 the constant rate.

It represents the y-intercept of the function.

The linear function is given by

y = mx + by=mx+b

The correct choice is y = 3x + 6.50

Answer:

A. Y= 3x6.50

Step-by-step explanation: This is the correct answer, because you can use the process of elimination on answers B and C due to how they are set up. And D is incorrect, because there is no decimal in 650 which is not the correct number in the problem. Therefore, A. Y= $3 for each downloaded movie multiplied by the monthly fee of $6.50 is the correct answer. Hope this helps ^-^.

Answer:

9:00

Step-by-step explanation:

The given equation can be solved to obtain x = 40.

A linear equation is a equation that has degree as one.

To find the solution of n unknown quantities n number of equations with n number of variables are required.

The given linear equation can be solved as follows,

0.2(x - 20) = 44 - x

=> 0.2x + x = 44 + 0.2 × 20

=> 1.2x = 48

=> x = 48/1.2

       = 40

Hence, the value of x for the given equation is found to be 40.

Answer: 4 hours

Step-by-step explanation:

$77.00 divided by $7.00 = 11 hours

11 hours- 3 hours (Friday)- 4 hours (Saturday)= 4 hours on Sunday

A total of 7 hours worked on Fri. and Sat.

Answer:

Caitlin worked 4 hours on Sunday.

Step-by-step explanation:

The answer is 4 hours because 7.00 multiplied by 7 (Because 3 + 4 = 7) is 49.00 and 77.00 minus 49.00 = 28.00 and since 1 hour = 7.00 and 7.00 multiplied by 4 is 28.00 then the answer must be 4 hours.

Answer:

11 years old

Step-by-step explanation:

Let x be Savannah's age

Ahsleys age should be 4 years less than three times Savannah's age

3x (Savannah) - 4 (years)

Then, you make an equation.

29 years old = 3x-4

simplify:

add four on both sides

33=3x

divide by three on both sides

x=11

Step-by-step explanation:

therefore the third angle is 51 degrees

Answer:

Step-by-step explanation:

Given  the expression

3 -x = 2+x

We re to find the number of solutions we will have:

Subtract 2 from both sides

3-x-3 = 2+x -3

-x = x -1

subtract x from both sides

-x - x = x - 1 - x

-2x =-1

Divide both sides by -2

-2x/-2 = -1/-2

x = 1/2

Since the value of x is just 1, hence the equation has just one solution.

Answer:

3.5

Step-by-step explanation:

The chemical acidity of a solution is measured in units of pH: pH=-log[H+], where [H+] is the hydrogen ion concentration in the solution. 1.58 x 10⁻⁹ is [H+] if the pH=8.8.

The term pH is defined as the negative logarithm of the [H+] hydrogen ion.

The isolated hydrogen ion, represented by the symbol H+, hence it is used to represent a proton. Because the bare nucleus can readily combine with other particles like electrons, atoms, and molecules, the  hydrogen ion.

The formula for calculating [H+] hydrogen ion is as follows:

pH = - log[H+]

Given pH = 8.8

8.8 = - log[H+]

-8.8 =  log[H+]

Taking Antilogarithm Both side

Antilog of [-8.8] = [H ]

By solving above expression [H+]

= 1.58 x 10⁻⁹

Thus, 1.58 x 10⁻⁹ is [H+] if the pH=8.8.

Step-by-step explanation:

Given that  ABCD is a parallelogram, we already know A (BD bisects AC) and B (AB ║ CD). Statement C (AC ≅ BD) will not be true for a parallelogram or rhombus.

Statement D (AC ⊥ BD) guarantees the parallelogram is a rhombus.

Answer:

a = -14

Step-by-step explanation:

1. distribute

24a + 48 = 9(2a - 4)

24a + 48 = 18a - 36

2. subtract 48 from both sides of the equation

3. simplify

4. subtract 18a from both sides of the equation

5. simplify

6. divide both sides of the equation by the same term
