Answer:

1. 7.1

2. 11.5

3. 24.2

Step-by-step explanation:

you use P.E.M.D.A.S. for all the equations.

so you do thr multiplication and then the addition

1. 2(1.8)+3.5= 3.6+3.5= 7.1

2. 2(4)+3.5= 8+3.5=11.5

3.2(6.9)+3.5= 13.8+3.5= 24.2

Answer:

  (x, y) = (0, -6)

Step-by-step explanation:

Substitute for y in the second equation:

  2x -4(8x -6) = 24

  2x -32x +24 = 24

  -30x = 0

  x = 0

  y = 8·0 -6 = -6

The solution is (x, y) = (0, -6).

Step-by-step explanation:

The solution is 14.86

The length of the third side of the right angle triangle is 14.86

What is a Triangle?

A triangle is a plane figure or polygon with three sides and three angles.

A Triangle has three vertices and the sum of the interior angles add up to 180°

Let the Triangle be ΔABC , such that

∠A + ∠B + ∠C = 180°

The area of the triangle = ( 1/2 ) x Length x Base

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

Given data ,

Let the triangle be ΔABC

Now , the triangle ABC is a right angle triangle

And the value of the base of the triangle BC = 10

The value of the height of the triangle AB = 11

Now , the hypotenuse of the triangle AC is calculated from Pythagoras Theorem

For a right angle triangle

From the Pythagoras Theorem , The hypotenuse² = base² + height²

Substituting the values in the equation , we get

AC² = AB² + BC²

AC² = 11² + 10²

AC² = 121 + 100

AC² = 221

Taking square roots on both sides of the equation , we get

AC = 14.86

Therefore , the value of AC is 14.86

Hence , The length of the hypotenuse of the right angle triangle is 14.86

Answer:

6

Step-by-step explanation:

You first have to choose from Wide and Narrow.

Let's call them W and N

Then you have to choose 3 different pen colors.

Let call them, 1, 2, 3

So There are two choices from W and N.

Then we pick the number: 1, 2, 3.

so If you pick W, you will have 3 choices. Same for N.

So in total: 6 choices.

W= 3 choices, W1, W2, W3

N= 3 choices, N1, N2, N3

so 6 in total.

Answer:

The new expression is:  12 x^2 - 12 x+ 30

Step-by-step explanation:

if C = x^2 + 7

and

D = 3 x^2 - 4 x + 3

Then, 3 C + 3 D can be obtained via:

3 ( x^2 + 7 ) + 3 ( 3 x^2 - 4 x + 3 )  = 3 x^2 + 21 + 9 x^2 - 12 x + 9 =

= 12 x^2 - 12 x+ 30

Answer:

d) firing will decrease for CS and increase for US

Step-by-step explanation:

The is the answer going by the probabilistic nature of the schedule. That is, as the probability of relieving reward increase has a direct effect on the CS leading to its decrease as well as a proportional increase for US. On the other hand, a decrease of probability of receiving reward will have an opposite effects on the schedule.

Answer:

Its asking you to multiply 5 and 3 together

5 x 3 = 15

Answer:

Step-by-step explanation:

Parentheses mean multiplication

5x3 = 15

Answer:

−8−x=x−4x

Step 1: Simplify both sides of the equation.

−8−x=x−4x

−8+−x=x+−4x

−x−8=(x+−4x)(Combine Like Terms)

−x−8=−3x

−x−8=−3x

Step 2: Add 3x to both sides.

−x−8+3x=−3x+3x

2x−8=0

Step 3: Add 8 to both sides.

2x−8+8=0+8

2x=8

Step 4: Divide both sides by 2.

2x
