Answer:

40 degrees

Step-by-step explanation:

- All internal angles of a triangle add up to 180 degrees.

- A right angle is 90 degrees.

90+50=140

subtract 140 from 180, which is 40 degrees.

Answer:

[tex](a)\ b = 8[/tex]

[tex](b)\ T = 3.1[/tex]

Step-by-step explanation:

Given

[tex]y = 2\sqrt x[/tex]

See attachment

Solving (a): Find b

At point b, [tex]x = 16[/tex]

So, the value of b is:

[tex]b = 2 * \sqrt{16[/tex]

[tex]b = 2 * 4[/tex]

[tex]b = 8[/tex]

Solving (b): Find T

First, we calculate the value of y at point T

[tex]y = 2\sqrt x[/tex]

At point T, [tex]x = 6[/tex]

So:

[tex]y = 2 * \sqrt 6[/tex]

[tex]y = 2 * 2.45[/tex]

[tex]y = 4.9[/tex]

To calculate T, we subtract the calculated height (y) from the value of b

[tex]T =b - y[/tex]

[tex]T = 8 - 4.9[/tex]

[tex]T = 3.1[/tex]

Answer:

90 degrees

Step-by-step explanation:

Answer:

x=103

Step-by-step explanation:

sum=(n-2)*180

sum=(6-2)*180

sum=4*180

sum=720

90+155+112+120+140+x=720

617+x=720

x=720-617

x=103

Answer:

3

because it says -3

so yeah

atleast i hope Im so bad at math

Answer: The length of one wall is 16ft

Step-by-step explanation: √256=16ft

Answer:

64ft

Step-by-step explanation:

256 divided by 4 since it is a square they are all even corners.

Step-by-step explanation:

x°+55°+40°=180°

x=180-95

Answer:

(-7, -2)

Step-by-step explanation:

Answer:

f(4) = 6

Step-by-step explanation:

Given the rule f(n) = 4f (n - 1) + 2 where f(1) = 3, f(n) is just a fancy way to name the variable y. As you've seen before, there are equations that are usually y equals x and something. For example:

y = mx + b

is the same thing as

f(n) = y = mn + b.

It might be that you have multiple of the same equation where f(n) and f(x) have two different outcomes.

The f(n) part (bolded) is the "x variable" in this equation. So in f(1), n = 1.

f(n) = 4f (n - 1) + 2

f(n) = (4fn - 4f) + 2

f(n) = (n) + 2

f(1) = 1 +2

3 = 3

Now do the same thing for f(4):

f(n) = 4f (n - 1) + 2

f(n) = (4fn - 4f) + 2

f(n) = (n) + 2

f(4) = 4 + 2

f(4) = 6

The answer is (1,-5), If you put those two on a graph, that point is where they collide.

Answer:

Pretty sure it's C.

Count the boxes

Answer:

16

Step-by-step explanation:

(x - y)² = x² - 2xy + y²

x = x and y = a

2xy = 8x

2*x*a = 8x

     a = [tex]\frac{8x}{2x}[/tex]

a = 4

a²  = 16

Answer:

48 Ounces of red

Step-by-step explanation:

4+3=7

112/7= 16

you will need to add 3 ounces of red and 4 ounces of blue 16 times

16 x 3 (ounces of red)= 48

Answer:

y=mx + c

Step-by-step explanation:

you find the answer using this equation

Answer:

A) 64.5

Step-by-step explanation:

A circle's measurement is 360°.

It is given that arcPQ is 113° and arcQM is 118°. Subtract 113 and 118 from 360:

360 - (113 + 118) = 129°

ArcPM is 129 degrees. Note that this is a inscribed, but not a central angle. m∠PQM = (ArcPM)/2

m∠PQM = (129)/2

m∠PQM = 64.5

A) 64.5 is your answer.

Answer:

6 hours

Step-by-step explanation:

For Bob

12 hours = 1 fence

1 hour = 1/12 fence

Together Bob and Jen

4 hours = 1 fence

1 hour = 1/4 fence

Now, for Jen:

1 hour = 1/4 - 1/12= 3/12 - 1/12 = 2/12=1/6

Find the amount of time Jen will need:

1/6 fence = 1 hour

1 fence = 6 hour

Answer:

The value of 6(2b-4) is 36.

Step-by-step explanation:

Given expression: 6(2b-4)

To find the value of 6(2b-4) at b=5, we need to substitute the b=5 in the expression, we get

6(2(5)-4)

= 6(10-4)

=6(6)

= 6x6=36

⇒ 6(2(5)-4)=36

Answer:

The value of 6(2b-4) when b=5 is 36.

Step-by-step explanation:

Given expression: 6(2b-4). To find the value of 6(2b-4) at b= 5, we need to substitute the b=5 in the expression, we get….Therefore, the value of 6(2b-4) is 36, when b=5.

Answer:

y - 20 = (-1/5)(x - 5)

Step-by-step explanation:

The slope of the given line is 5.  The slope of any line perpendicular to the given line is the negative reciprocal of the given slope:  

Slope of perpendicular line here is -1/5.

We use the point-slope formula as a framework here:

y - 20 = (-1/5)(x - 5)

Answer:

9/5 or 1.8

Step-by-step explanation:

triangle aed is larger than triangle abc by a scale factor of 5; we know this because side ed is 5 units and cb, the corresponding side in triangle abc, is 1. if ad has a length of 9, the length of ab must be 9 divided by five. thus, z is equal to 9/5 or 1.8.
