Please help! I do not know how to find the unknown variables using the Pythagorean theorem. Any help will be greatly appreciated:))

Answer:

x=7/2

Step-by-step explanation:

Answer:

x=7/2

Step-by-step explanation:

x-(2x+1)=8-(3x+2)

x-2x-1=8-3x-2

-x-1=6-3x

+x on both sides

-1=6-2x

-6 on both sides

-7=-2x

7=2x

÷2 on both sides

7/2=x

Answer:

371.26

Step-by-step explanation:

Using trig we can do tan(68)*5 to find the height of the parallelogram, after this we can do the height times 30 to find the answer

[tex]f(x) = - \sqrt{x + 5 + 4} + 1 - 3[/tex]

[tex]f(x) = - \sqrt{x + 9} - 2[/tex]

Answer:

30%

Step-by-step explanation:

Answer: good luck

Step-by-step explanation:

Answer:

30

Step-by-step explanation:

i believe that the 13 is there to throw you off. anyway to solve just do 5•12=60

60÷2=30 so 30 is area of triangle

area of triangle =1/2×base×height

area of triangle=1/2×12×5

area of triangle=30 unit²

Answer:

B

Step-by-step explanation:

Using the pythagorean theorem A^2 + B^2 = C^2 the only numbers that work are those in choice B. 8 short leg, 15 long leg, 17 hypotenuse.

8^2 + 15^2 = 17^2 = 64 +225=289 = 289=289 therefor proving these set of numbers are a right triangle.

Answer:

The answer is above the solid line.

Step-by-step explanation:

Answer:

Step-by-step explanation:

13). Area of a square = (Side)²

                                   = (BC)²

     Since, diagonals of a square bisect each other at 90°,

     ΔBOC is a right triangle.

     By applying Pythagoras theorem in the given triangle,

     BC² = OB² + OC²

     BC² = 2(OB)²

     BC² = 2(7√2)²

     BC = [tex]\sqrt{196}[/tex]

     Area of square ABCD = (BC)²

                                          = (√196)²

                                          = 196 units²

14). Measure of interior angles of the regular hexagon = 120°

     Area of the regular hexagon = [tex]\frac{3\sqrt{3}}{2}(\text{side})^2[/tex]

      From the given picture,

      m∠BAC = m∠ABC = m∠ACB = 60°

      Therefore, ΔABC is an isosceles triangle.

      And all sides of this triangle will be equal in measure.

      AB = AC = BC = 9 units

      Area of the given regular hexagon = [tex]\frac{3\sqrt{3}}{2}(9)^2[/tex]

                                                                 = 210.44 square units

                                                                 ≈ 210.4 square units

Step-by-step explanation:

Answer is:

X is 1, very simple

Answer:

f(x) = A*∛(x + 2) + 3

Step-by-step explanation:

Suppose a generic cube as:

f(x) = A*∛(x - b) + C

We will have a turning point at the x value:

x = b

Then if we have a turning point at (-2, 3)

This means that the turning point is at x = -2 and y = 3

Then b = -2

And our cube root function will be something like:

f(x) = A*∛(x - (-2)) + C

f(x) = A*∛(x + 2) + C

And we know that f(-2) = 3

then:

f(-2) = A*∛(-2 + 2) + C = 3

f(-2) =  A*∛(0) + C = 3

      = C = 3

Then the general equation will be something like:

f(x) = A*∛(x + 2) + 3

b) 25,000,000

c) B

Step-by-step explanation:

a) 2350 X 1,000,000 = 2,350,000,000

b) 25 X 10^6 = 25,000,000

c) sqrt(90000) =300

Answer:

the second answer is the answer

Step-by-step explanation:

If there are 40 kids and 22 of them play soccer that leaves you to subtract 22 from 40 which gives you 18. After that, you put the rest of the 18 students over a total of 40 and divide to get the decimal .45 and if you convert that into a percent you are left with 45%.

1. 40-22=18

2.18/40=.45

3.45=45%

Answer:

5/18

Step-by-step explanation:

Volume= length•width•height

5/6•1/2= 5/12

5/12•2/3= 10/36= 5/18

Answer:

78.8 %

Step-by-step explanation:

From the question,

Area of the square = L²

A = L²

Where L = Length of the square.

From the diagram,

L = 4 in

Therefore,

A = 4²

A = 16 in².

Also,

Area of the circle (A') = πr²

Where r = radius of the circle.

Given: r = 2 in

Therefore,

A' = 22/7(2²)

A = 12.6 in²

Hence,

The probability that a randomly selected points within a square falls in the blue shaded area (Pr) = A'/A

Pr = 12.6/16

Pr = 0.7875

Pr(%) = 78.75

Pr(%) = 78.8 %
