if a ladder is to reach a height of 5.6m, the base must be at least 1.4m from the wall. How long should the ladder be in order to meet this safety regulations?

Answers

Answer 1
Base x height divided by 2 I think this is correct
Answer 2

Answer:

≈ 5.72 m

Step-by-step explanation:

Use Pythagorean as the ladder is going to be a hypotenuse of a formed right triangle with legs of 5.6 m and 1.4 m

Ladder length:

√5.6² + 1.4² = √32.76 ≈ 5.72 m rounded

Please show work

Answers

Answer:

x = 1

General Formulas and Concepts:

Pre-Algebra

Order of Operations: BPEMDAS

Brackets Parenthesis Exponents Multiplication Division Addition Subtraction Left to Right

Equality Properties

Step-by-step explanation:

Step 1: Define Equation

3(4x - 5) - 4x + 1 = -6

Step 2: Solve for x

Distribute 3:                    12x - 15 - 4x + 1 = -6Combine like terms:       8x - 14 = -6Isolate x term:                 8x = 8Isolate x:                          x = 1

Step 3: Check

Plug in x into the original equation to verify it's a solution.

Substitute in x:                    3(4(1) - 5) - 4(1) + 1 = -6Multiply:                               3(4 - 5) - 4 + 1 = -6Subtract:                              3(-1) - 4 + 1 = -6Multiply:                               -3 - 4 + 1 = -6Subtract:                              -7 + 1 = -6Add:                                     -6 = -6

Here we see that -6 does indeed equal -6.

∴ x = 1 is the solution to the equation.

Pls help, some question I already have the answer but its different from the book answer​

You need to calculate the height of the cone which would be OV, not VB

Using Pythagorean theorem:

OV = sqrt(37^2-12^2)

OV = 35

Now you have the height to solve everything.

This is a semi circle so volume and surface area would be 1/2 of a full cone.

A) v = 1/2 x pi x r^2 x h/3

V = 1/2 x pi x 12^2 x 35/3

V = 1/2 x pi x 144 x 35/3

V = 840pi

B) sa =1/2 x pi x r(r + sqrt(h^2+r^2))

Sa = 1/2 x pi x 12(12+ sqrt(35^2+12^2))

Sa= 923.63 round as needed.

C) volume of hemisphere with 4cm diameter:

2/3 x pi x 2^3 = 5.33pi

Divide volume of semi cone by volume of hemisphere:

840pi/5.33pi = 157.5

solve for k
9/10 = 10/k

Answers

Answer:

k = 100/9

Step-by-step explanation:

In this question, we will be solving for "k".

Solve:

9/10 = 10/k

Cross multiply.

(9 · k) = (10 · 10)

9k = 100

Divide both sides by 9

k = 100/9

Your answer would be k = 100/9

Evaluate I5| - |-5|.

Answers

Answer:

| 5 | - | -5 | = 0

Step-by-step explanation:

For this problem, the absolute value operator creates the positive value of whatever is contained in it.

This expression can be rewritten as follows:

| 5 | - | -5 |

= 5 - 5

= 0

Hence, the expression simplifies to 0.

Cheers.

Answer:

0

Step-by-step explanation:

This is the answer because:

1) I  I = Absolute Value

Absolute Value means that whatever number is inside it, is positive.

2) The I-5I = 5:

5 - 5 = 0

Therefore, the answer is 0.

A shirt marked $320.00 was sold at a discount of 5%. What was the selling price?

Answers

Answer:

304

Step by step:

Using your calculator 5% of 320 is 16.

Since it was a discount, you subtract 16 since you're marking it down.

320-16=304

304 is your answer

How do I know? Well, there it takes 20+20+20+20+20 to equal a hundred. We can do this same math for this problem. 16 x 20 is 320

Answer:

$304.00

that is really freaking expensive shirt lol.

i thought you said shlt,  not shirt lol

anyway...

Step-by-step explanation:

320 times 0.05

(don't make the mistake of 0.5  that is 50%, not 5%. )

320*0.05= 16

subtract it
