Answer:

8x to the power three to the power 12

Step-by-step explanation:

56x^13

(7x) times (2x^4)^3


let’s focus on the right side.

(2x^4)^3

We need to distribute the ^3 to the 2 and x^4.

(2^3) (x^4)^3

8 (x^4)^3

When an exponent has an exponent, you multiply them.

8 (x^12) ⬅️ we got this by multiplying 4 and 3.


(7x)(8x^12)

When you have multiply exponents, you add the numbers. 7x can also be written as 7x^1.

1+ 12= 13

Multiply 7 and 8.


56x^13



Adrien has 4 liters of milk. He drinks y liters each day.

a) If Adrien has x liters of milk left after one week, express x in terms of y.

b) State the independent and dependent variables in the question

Answers

Answer:

A) X = 4 - 7Y

B) Independent Variable: Y, Dependent Variable: X

Step-by-step explanation:

Explanation for A:

We form a simple equation, knowing that if he drinks y liters each day after one week it would be 7Y. Then, we'd subtract it from 4

So equation would be X = 4 - 7Y

Explanation for B:

The independent is Y because doesn't change or get affected by another variable, and the dependent variable is X because depending on the value of Y, X will change accordingly.

Step-by-step explanation:

#18 complementary

3x +45 = 90

3x + 45-45 = 90 -45

3x = 45

Divide both sides by 3

3x/3 = 45/3

x = 15

#20 supplementary

2x + 3x + 25 = 180

5x + 25 = 180

5x + 25 - 25 = 180 -25

5x = 155

Divide both sides by 5

5x/5 = 155/5

x = 31

#15 - vertical

4x - 25 = 75

4x - 25 + 25 = 75 + 25

4x = 100

Divide both sides by 4

4x/4 = 100/4

x = 25

#16 - complementary

4x + 2x = 90

6x = 90

divide by 6 each side

x = 15

#19 complementary

x -20 + x = 90

2x -20 = 90

2x -20 + 20 =90 +20

2x = 110

Divide both sides by 2

2x / 2 = 110/2

x = 55

Triangles ABC and DEC are similar. Side DE is 1.8 feet, side EC is 4 feet, and side BE is 0.8 foot.

Part A: Describe how to draw triangles ABC and DEC separately. Be sure to give the lengths of sides BC, DE, and EC in the description.

Part B: Find side AB. Show each step of your work.

Answers

The lengths of sides BC, DE, and EC in triangle DEC are given as [tex]4[/tex] feet, [tex]1.8 feet,[/tex] and 0.8 foot, respectively. The length of side [tex]AB[/tex] is approximately [tex]3.36[/tex] feet.

What is the line segment?

Part A:

To draw triangles  [tex]ABC[/tex] and  [tex]DEC[/tex] separately, follow the steps below:

Draw a straight line segment DE with length  [tex]1.8[/tex] feet.

From point D, draw a line segment DC perpendicular to DE with length 4 feet.

Connect point E and point C with a straight line segment EC.

From point B, draw a line segment BE perpendicular to BC with length 0.8 foot.

Draw a straight line segment BC that intersects line segment DC at point A.

Connect point A and point B with a straight line segment AB.

The lengths of sides BC, DE, and EC in triangle DEC are given as [tex]4[/tex] feet, [tex]1.8 feet,[/tex] and 0.8 foot, respectively.

Part B:

Since triangles  [tex]ABC[/tex] and [tex]DEC[/tex] are similar, their corresponding sides are proportional. Let x be the length of side AB. Then we have:

[tex]AB/DE = BC/EC[/tex]

Substituting the given values, we get:

[tex]x/1.8 = BC/0.8[/tex]

Solving for BC, we get:

[tex]BC = 0.8x/1.8[/tex]

Since BC and EC are the two legs of a right triangle DEC, we can use the Pythagorean theorem to find BC:

[tex]BC^2 + EC^2 = DE^2[/tex]

Substituting the given values, we get:

[tex](0.8x/1.8)^2 + 4^2 = 1.8^2[/tex]

Solving for x, we get:

[tex]x = 1.8 * (sqrt(1.8^2 - 4^2)) / 0.8[/tex]

[tex]x \approx 3.36 feet[/tex]

Therefore, the length of side [tex]AB[/tex] is approximately [tex]3.36[/tex]  feet.

please what i it???

Answers

12/18 times 2=24/36
n=24/36

Answer:

n = 24

Step-by-step explanation:

first put the equation into fraction form and cross multiply:

12/18 = n/36

12(36) = n(18)

432 = 18n

now isolate the variable:

432/18 = 18n/18

24 = n

Answer is simply 3 :)))))))

What is Probability?

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

The theoretical probability of both rolls equaling a sum greater than 10 is 3 over 36.

As, Expected number of outcomes = theoretical probability * number of trials

Expected number of outcomes = 3/36 x 108

                                                    = 9

Thus, the required value is 9.

ANSWER ASAP PLEASE What is the solution for the system of linear equations shown in the graph? a coordinate grid with one line that passes through the points 0 comma 1 and 1 comma 2 and another line that passes through the points 0 comma 0 and 1 comma negative 3

Answers

Step-by-step explanation:

The solution of for the system of linear equations shown in the graph is x = -1/2 and y = 3/2.

Given points of two lines:-

Line 1 : (0,0) , (1,-3)

Line 2 : (0,2) , (-1,1)

Let the Equation of Line 1 : y = mx + c

m = (-3-0)/(1-0) = -3/1 = -3

Putting (0,0) in  y = mx + c, we get

0 = -3*0 + c

0 = 0 + c

c = 0

Hence,

Equation of Line 1 : y = -3x or y + 3x = 0  ...(1)

Similarly, we can find,

Equation of Line 2 : y = x + 2 or y - x = 2  ...(2)

(1) - (2),

4x = -2

x = -2/4 = -1/2

Putting the value of x in (2), we get,

y - (-1/2) = 2

y + 1/2 = 2

y = 2-(1/2)

y = 3/2

So basically you just translate the problem into math form. 33 is a #, is is an = sign so, 33 = so far. Then 15 is less than k, which is not 15 - k but k - 15. There's a difference. Say k is 30, so 30 - 15 and not 15 - 30. So then you have 33 = k - 15, then I just switched it around to look better and done.
