Is 2 squared + 3 squared = 4 squared a true statement? Explain.

Answer:m∠1 = 145°

m∠2 = 35°

m∠3 = 35°

m∠4 = 145°

m∠5 = 145°

m∠6 = 35°

m∠7 = 35°

m∠8 = 145°

Step-by-step explanation:

The required value of a is 20°.

In geometry, complementary angles are defined as two angles whose sum is 90 degrees. In other words, two angles that add up to 90 degrees are known as complementary angles.

Now it is given that,

m22 = (a + 15)° and m23 = (a + 35)°

Let m22 and m33 be the angle between HL and HJ.

And since HL is perpendicular to HJ therefore they are complement ot each other.

Thus,

m22 + m23 = 90°

⇒ (a + 15)° +  (a + 35)° = 90°

⇒ a° + 15° +  a° + 35° = 90°

⇒ 2a° +50° = 90°

⇒ 2a° = 90° - 50°

⇒ 2a° = 40°

⇒ a° = 40°/2

⇒ a° = 20°

Thus, the required value of a is 20°.

Answer:

There is no solution

Step-by-step explanation:

7−3r=r−4(2+r)

Step 1: Simplify both sides of the equation.

7−3r=r−4(2+r)

7+−3r=r+(−4)(2)+(−4)(r)(Distribute)

7+−3r=r+−8+−4r

−3r+7=(r+−4r)+(−8)(Combine Like Terms)

−3r+7=−3r+−8

−3r+7=−3r−8

Step 2: Add 3r to both sides.

−3r+7+3r=−3r−8+3r

7=−8

Step 3: Subtract 7 from both sides.

7−7=−8−7

0=−15

Step-by-step explanation:

The cube root of 15,409,000 = 248.84 yards.

There are 1760 yards in a mile

One edge of a cube = 248.84 / 1760 = .141386 miles.

So a cube would be .00283cubic miles. Your answer does not reach a hundredth place, I don't think.

Given problem;

   A = [tex]\pi[/tex] r²

   Solve for π;

To solve for π implies that we make it the subject of the expression.

So;

       A = π r²

      Now multiply both sides by [tex]\frac{1}{r^{2} }[/tex]

 So;

                A x [tex]\frac{1}{r^{2} }[/tex]   = [tex]\pi[/tex] x r² x [tex]\frac{1}{r^{2} }[/tex]

              r² cancels out from the right side and leaves only π;

                  π = [tex]\frac{A}{r^{2} }[/tex]

So    [tex]\pi = \frac{A}{r^{2} }[/tex]

Answer:

y=4/5x+2

Step-by-step explanation:

Answer:

y=0.8x+2

Step-by-step explanation:

First, you would figure out the slope using the following equation: (y2-y1)/(x2-x1)=slope.

So, (2--2)/(0--5)= 4/5, or 0.8. This would be the slope.

Then, you would figure out b by putting a data point from the given ones. I chose (0, 2).

2=0.8(0) + b --> 2=0 + b --> 2=b

So, the final equation is y=0.8x+2

Step-by-step explanation:

Vertical angles are equal to each other. So, to solve, write the equation:

Divide both sides by 2

x = 65

Answer:

4 days

Step-by-step explanation:

For Jayla:

[tex]Base\ Amount = \$30[/tex]

[tex]Additional = \$12[/tex] daily

For Carlos:

[tex]Base\ Amount = \$50[/tex]

[tex]Additional = \$7[/tex] daily

Represent the number of days with d

Jayla's expression can be represented using:

[tex]30 + 12*d[/tex]

Carlos' can be represented as:

[tex]50 + 7 * d[/tex]

Equate both expressions:

[tex]50 + 7 * d = 30 + 12 * d[/tex]

[tex]50 + 7d = 30 + 12d[/tex]

Collect Like Terms

[tex]12d - 7d = 50 - 30[/tex]

[tex]5d = 20[/tex]

Hey there!

Given;

The given figure is a Right angled triangle, taking reference angle as angle B.

Hypotenuse= AB=5

Base= CB= 4

Perpendicular= AC=b

Using Pythagorean theorem.

[tex] {h}^{2} = {p}^{2} + {b}^{2} [/tex]

[tex]p = \sqrt{ {h}^{2} - {b}^{2} } [/tex]

Put all values.

[tex]b = \sqrt{ {5}^{2} - {4}^{2} } [/tex]

[tex]b = \sqrt{25 - 16} [/tex]

[tex]b = \sqrt{9} [/tex]

Therefore, the value of b is 3.

Answer:

Option B.

Step-by-step explanation:

The graph attached shows the amount of Michael's paycheck based on 40 hour wok along with commission from the sales.

There are two variables plotted on the graph.

On x-axis → Amount of sales

On y-axis → Amount of paycheck he received

Point (0, 100) shows the y-intercept.

Since, y-coordinates show the amount of paycheck, y-intercept will show the amount ($100) at zero sales.

Therefore, Option B will be the correct option.

Answer:

The change in available disk space is −6% per episode

Step-by-step explanation:

Given that :

Available disk space changed from 81% to 9% after recording 12 episodes of a show

Each episode requires the same amount of disk space

Change in disk space =

Final % = 9%

Initial percentage = 81%

Change = final value - initial value :

(9 - 81)% = -72%

72% reduction in disk space

Space taken up per episode :

Reduction in space / number of episodes

= -72% / 12

=- 6%

Answer:

1. $1050

2. $5.25t = c.

3. $813.75 ÷ 5.25 = 155.

Step-by-step explanation:

For the first day, 200 kid tickets were purchased. We know that a singular movie ticket is $5.25. From this information, I know I have to multiply.

200 x 5.25 = 1050.

The answer to number one is $1050.

So t will be the variable that represents the number of kid's tickets and c is the total cost, from this equation, I would create this equation:

$5.25t = c.

I put 5.25 down because that is the cost of a singular child ticket. It would be multiplied by t (total amount of child tickets) and the product would be the total cost of those tickets (c).

The answer to number 2 is $5.25t = c.

Another day, the total cost of the tickets were $813.75. One kid movie ticket is $5.25, so this calls for division.

$813.75 ÷ 5.25 = 155.

The total amount of tickets that were purchased that day was 155 child tickets.

The total amount of tickets that were purchased that day was; 155 child tickets.

An equation is an expression that shows the relationship between two or more numbers and variables.

Given that 200 kid tickets were purchased. We know that a singular movie ticket is $5.25.

200 x 5.25 = 1050.

The total cost of those tickets is $1050.

Let t be the variable that represents the number of kid's tickets and c is the total cost, from this equation:

$5.25t = c.

Now multiplied by t (total amount of child tickets) and the product would be the total cost of those tickets (c).

The answer is $5.25t = c.

On another day, the total cost of the tickets was; $813.75. One kid movie ticket is $5.25 thus;

$813.75 ÷ 5.25 = 155.

The total amount of tickets that were purchased that day was; 155 child tickets.

Answer:

Slope = 2

Step-by-step explanation:

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

8-0/4-0

m = 2

Answer:

A) m = 16/5

Step-by-step explanation:

We need to find the slope between a choice of two points in this function table. I'll choose points (5,16) and (10,32) however you can choose any point you want.

To find "m" which is the slope, we need to do the following:

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

m = (32-16)/(10-5)

m = 16/5

The answer is A) m = 16/5

Answer: A) y= -1/2x+5
