2*4=8

Answer: B. 200ft

Step-by-step explanation:

Pythagorean theorem so a^2+b^2+c^2 or 120^2+160^2=c^2 where c is the value for the diagonal so solving for c to get 200

Answer:

200, 160

Step-by-step explanation:

if perimeter is 240 it means sides are 40 by 80.

if he does not need to place fencing on one side, they remove one 80 or 40,

40+80+80=160 or 40+40+80=200

Answer:

200 160

Step-by-step explanation:

if the perimeter is 240, the length is 80 and width is 40.

40+80+80=200

80+40+40=160

Answer:

B. f(x) = -x + 2

Step-by-step explanation:

First, you find the point on the y-axis which is (0,2) in this problem.

This will be your b in y = mx+ b

Then, you'll find how many blocks you are moving or rise over run. Which is -1/1 or -1.

This will be your m in y = mx + b

But we don't write the 1 so it will just be -x

Now add all your numbers in the standered form (y = mx + b) to get y = -x + 2 or f(x) = -x + 2

Answer: 11.7

Explanation:

-1.7-(-13.4)=11.7

Answer:

$8.14

Step-by-step explanation:

Given data

Cost of surfboard= $22

Mark up = 37%

Required

The amount of the markup

let us find 37% of $22

=37/100*22

= 0.37*22

= $8.14

Hence the amount of the markup is $8.14

Answer:

Answer:

Anything between 0-90 degrees.

Step-by-step explanation:

Not enough information to find x.

Answer:

x = 4

Step-by-step explanation:

Label the points from A-F. I attached an image of how I labeled the points.

Notice that there are similar triangles here:

Set up proportions to find the values of x, y, and z.

Let's make this problem simpler by incorporating only 2 variables instead of 3.  Let's say that the total distance between the two poles is distance d. Instead of z, let's call it d - y.

Substitute known values or variables into the proportions.

Cross-multiply and simplify Equation I.

Cross-multiply and simplify Equation II.

We now have two equations that are equal to dx, so we can set them equal to each other.

Add 6y to both sides of the equation.

Divide both sides of the equation by 6.

We can substitute this value of d back into either Equation I or II. I am going to substitute d into Equation II.

Cross-multiply and simplify the equation.

Divide y from both sides of the equation.

Divide both sides of the equation by 3.

The guylines from the top of one pole to the bottom of the other cross at the height of 4 ft off the ground.

It's hard to explain but basically one side is just (n) another is (n(square root sign))and another is (2n.)    

So the answer Is a because in this case (n) is 4  

Answer:

x=−12

Step-by-step explanation:

Let's solve your equation step-by-step.

x=23−25−10

Step 1: Simplify both sides of the equation.

x=23−25−10

x=23+−25+−10

x=(23+−25+−10)(Combine Like Terms)

x=−12

Answer:

y=1.8

Step-by-step explanation:

first change the fraction into a decimal.

4/5 =0.8

plus the 0.8 to both sides

y=1.8

Answer:

[tex]y - \frac{4}{5} + \frac{4}{5} = 1 + \frac{4}{5} \\ y = \frac{5 + 4}{5 } \\ y = \frac{9}{5} [/tex]

Answer:

500000

Step-by-step explanation:

We need to find the value of the given expression :

[tex]5^{\dfrac{5}{2}}\times 20^{\dfrac{3}{2}}\div 10^{-2}[/tex]

We can do it as per BODMAS rule.

[tex]5^{\dfrac{5}{2}}\times (\dfrac{20^{\dfrac{3}{2}}}{10^{-2}})\\\\=5^{\dfrac{5}{2}}\times {20^{\dfrac{3}{2}}}\times {10^{2}}\\\\=5^{\dfrac{5}{2}}\times {20^{\dfrac{3}{2}}}\times 100\\\\=5^{\dfrac{5}{2}}\times {(5\times 4)^{\dfrac{3}{2}}}\times 100\\\\=5^{\dfrac{5}{2}}\times {(5^{\dfrac{3}{2}})\times (4)^{\dfrac{3}{2}}}\times 100\\\\=5^{(\dfrac{5}{2}+\dfrac{3}{2})}\times 2^2^{\dfrac{3}{2}}\times 100\\\\=5^4\times 2^3\times 100\\\\=625\times 8\times 100\\\\=500000[/tex]

So, the required answer is 500000.
