Terry is 4 feet tall, and his shadow is 3 feet long. How many feet is it from the top of Terry's head to the top of his shadow's head?.

Answer: 11

Step-by-step explanation:

49.5/9 = 5.5

5.5 x 2 =11

11x9=99

99/2=49.5

Answer:

43.7

Step-by-step explanation:

7[tex]7^{2} +7^{2} =\sqrt{98} \\\sqrt{98}=9.899494937\\ That is the measurement for the dotted line. If we round it like they did in the example it would be 9.90. That is the measurement for all the sides of the square. \\We need the measurement for only 3 sides of the square and the two outer sides of the triangle (7ft)\\7ft + 7ft + 9.90 + 9.90 + 9.90 = 43.7\\\\Joshua added the 7's and they square rooted them for the Hypotenuse.\\Then the perimeter of all sides did not need any square roots.[/tex]

Answer:

1/9

Step-by-step explanation:

1/3 - 2/9

Get a common denominator of 9

1/3 *3/3 = 3/9

3/9 - 2/9

1/9

Given:

Consider the piecewise function is

[tex]f(x)=\left \{\begin{matrix}x^2+4x,\text{ if } x\leq -1\\ x, \text{ if }-1<x\leq 1\\-1,\text{ if }x>1\end{Matrix}\right.[/tex]

To find:

The value of the function at indicated values.

Solution:

We know that, [tex]-2,-\dfrac{3}{2},-1[/tex] are less than or equal to -1. So, for these values the function is [tex]f(x)=x^2+4x[/tex].

For x=-2,

[tex]f(-2)=(-2)^2+4(-2)[/tex]

[tex]f(-2)=4-8[/tex]

[tex]f(-2)=-4[/tex]

Similarly,

For [tex]x=-\dfrac{3}{2}[/tex].

[tex]f(-\dfrac{3}{2})=(-\dfrac{3}{2})^2+4(-\dfrac{3}{2})=-\dfrac{15}{4}[/tex]

For [tex]x=-1[/tex].

[tex]f(-1)=(-1)^2+4(-1)=-3[/tex]

We know that, 0 is lies between -1 and 1. So, for this values the function is [tex]f(x)=x[/tex].

For x=0,

[tex]f(0)=0[/tex]

We know that, 25 is greater than 1. So, for this values the function is [tex]f(x)=-1[/tex].

For x=25,

[tex]f(25)=-1[/tex]

Therefore, the required values are, [tex]f(-2)=-4, f(-\dfrac{3}{2})=-\dfrac{15}{4},f(-1)=-3,f(0)=0,f(25)=-1[/tex].

I'm not sure if I'm right or wrong but I got the same values to all the triangle maybe if u use angles u might get a different answer I'm not sure

Answer:

I think its Yes

Answer:

3

Step-by-step explanation:

Step 1:

2x + y = 9          Equation

Step 2:

2 ( 3 ) + y = 9    Input x

Step 3:

6 + y = 9     Multiply

Step 4:

y = 9 - 6     Subtract 6 on both sides

Answer:

y = 3

Hope This Helps :)

Since we know that the 2 lines are parellel, we know that the angles will add up to 180

sooo

180-119=61 (The angle in the traingle)

We know that the angles of a trinalge add up to 180

61+18+e=180

e=101 degrees

Answer:

Its 22 squared feet

Step-by-step explanation:

you multiply everything and then divide by 1/2 because it's a triangle, so you would use the equation for that.

Answer:

68°F is 20°C

Step-by-step explanation:

C = (5/9)(F - 32)

C = (5/9)(68 - 32)

C = (5/9)(36)

C = 5 * 4

C = 20

Answer: 68°F is 20°C

Answer:

n = -8

Step-by-step explanation:

Original Equation:

8n + 8 = -56

Subtract 8 from boths sides.

8n = -64

Divide both sides by 8

n = -8

Hope this helped :)

Please consider Brainliest :)

Step-by-step explanation:

its -8

8n + 8 = 56

8n + 8 - 8 = 56 - 8

8=−64

8n/ 8 -= -64

8n / 8 = -64 / 8

simplified = n = - 8

n equals -8

Complete Question

You are measuring walnuts for banana-walnut oatmeal and a spinach and walnut salad. You need 3/4 cup of walnuts for the oatmeal and 7/8 cup of walnuts for the salad. You have a 1/8 -cup scoop. Complete the descriptions of two different ways to find how many scoops of walnuts you will need. Enter all non-whole number answers as mixed numbers in simplest form.

Answer:

13 scoops

Step-by-step explanation:

Description 1

Step 1

3/4 cup of walnuts for the oatmeal

7/8 cup of walnuts for the salad

Total cups of walnuts needed for both salad and oatmeal =

3/4 cups + 7/8 cups

(3/4 + 7/8)

(6 + 7/8)

= 13/8 cups of walnuts

= 1 5/8 cups of walnuts

Step 2

You have a 1/8 -cup scoop

The number of cup scoops of walnuts need is calculated as

1 5/8 cups ÷ 1/8 cup scoop

= 13/8 ÷ 1/8

= 13/8 × 8/1

= 13 scoops

Therefore, 13 scoops of walnuts is needed.

Description 2

3/4 cup of walnuts for the oatmeal

7/8 cup of walnuts for the salad

1/8 cup scoop

Therefore,

(3/4 + 7/8) ÷ 1/8

=(13/8) ÷ 1/8

= 13 scoops of walnuts are needed

[tex]f(2) = \frac{1}{2} \times 2 = 1\\f^{-1}(1) = 2 \times 1 = 2\\f^{-1}(f(2)) = f^{-1}(1) = 2[/tex]

Note: [tex]f^{-1}(f(x)) = x[/tex] because f -1 and f cancel each other out.

Answer:

f(2) =  

⇒ 1

f−1(1) =  

⇒ 2

f−1(f(2)) =  

⇒ 2

f−1(−2) =  

⇒ -4

f(−4) =  

⇒ -2

f(f−1(−2)) =  

⇒ -2

Answer:

Domain(x): -2,2,3

Range(y): -1,4,5,6

(I put them in order numerically)

Step-by-step explanation:

The Domain is all the x values of the points given. It's always the first number of a point.

The range is the y values, it's always the second number given in a ordered pair!

Hope this helps! :)

f(x) = -2

f(x) is the same thing as x

f(x) is the same thing as -2

Now think about it. If f(x) and -2 are the same thing, what is x?

Answer:

y = 7x - 7

Step-by-step explanation:

1st we can look at the meaning of a slope intercept equation

y = mx = b

m = the slope

b = the y-intercept

now when looking at your equation you can plug in your numbers.

y = 7x - 7 is your final answer

Answer:

Add 8 to both sides

Step-by-step explanation:

Normally after adding 8 to both sides you'd solve for x by then dividing by -5, but they just want u to explain what to do lol.
