8 divided by 2 (2+2)

Answer:

76

Step-by-step explanation:

When you solve the equation you will do parentheses first (10+2) which equals 12 then you carry everything down. Next you will multiply 3 x 12 to get 36 then you carry the 20 and  2 down. Next you will multiply 20 by 2 to get 40 and then add 36 + 40 to get 76.

3(10+2) +20 x 2

3(12) +20 x 2

36 + 20 x 2

36 + 40

76 : answer

The expression 3⋅(10+2)+20⋅2 simplifies to 76.

The given expression is [tex]$$3 \cdot (10+2) + 20 \cdot 2[/tex]

Let's simplify it step by step:

1. First, perform the operation inside the parentheses: [tex]3 \cdot 12 + 20 \cdot 2[/tex]

2. Then, perform the multiplication: [tex]36 + 40[/tex]

3. Finally, perform the addition: [tex]76[/tex]

So, the expression is equal to 76.

Answer:

Babatunde weigh on the Moon would be 124.8 N

Step-by-step explanation:

* The wight of an object on the earth is mg , where m is the the

  mass of the object in kg and g is the acceleration of gravity which

  is 9.8 m/s²

* The mass of an object on earth is the same as the mass of the

  same object on the moon but the weight of the object on the

  earth is different from the weight of the same object on the

  moon because the gravity on the earth different from on the moon

* The wight on the moon is mg , where m is the the mass of the

  object in kg and g is gravitational field strength on the Moon

  which is 1.6 N/kg

∵ Babatunde has a mass of 78 kg

∵ The mass on the moon = the mass on the earth

∵ On the moon the gravitational field strength is 1.6N/kg

∵ Weight = mg

∴ Babatunde weigh = 78 × 1.6 = 124.8 N

* Babatunde weigh on the Moon would be 124.8 N

Babatunde's weight on the Moon is calculated by multiplying his mass (78 kg) by the Moon's gravitational field strength (1.6 N/kg), resulting in 124.8 newtons.

To calculate Babatunde's weight on the Moon, we use the formula for weight, which is the product of mass and gravitational field strength. On Earth, the average acceleration due to gravity is approximately 9.8 m/s², and on the Moon, it is about 1.6 N/kg. Babatunde's mass on Earth is 78 kg. Therefore, to calculate his weight on the Moon, we multiply his mass by the Moon's gravitational field strength.

Weight on the Moon = Mass × Gravitational field strength on the Moon

Weight on the Moon = 78 kg × 1.6 N/kg

Weight on the Moon = 124.8 N

Babatunde would weigh 124.8 newtons on the surface of the Moon, significantly less than his weight on Earth due to the Moon's lower gravitational pull.

the answer is (8,1)

so..

C. (8,1) is a solution to both equations so it is a solution to the system

The pair (8,1) satisfies both of the given equations, so it is indeed a solution to the system, making option C correct.

For the first equation:

8 - 3(1) = 5
8 - 3 = 5
5 = 5 (True)

The range of values for the measurement 300 ±2% is 294 to 306. This involves considering the concept of accuracy and precision in measurements.

The question is asking for the range of measurements that can be made if the measurement is 300 units with a 2% uncertainty. In mathematical terms, an uncertainty of 2% means we can make measurements that are 2% less or 2% more than the given value.

First you must calculate 2% of 300 to find the value representing the uncertainty. This is (2/100) * 300 = 6. Hence, the measurement can be 6 units less than or more than 300.

Therefore, the range of measurements we can make is from (300 - 6) to (300 + 6). This results in a range of 294 to 306.

This concept is grounded in accuracy and precision. Accuracy describes the close proximity of a measurement to a specific value, while precision relates to the consistency of output using the same measurement process.

Answer: The graph is attached.

Step-by-step explanation:

 We must design a graph so that the x-axis represents the Time in hours and the y-axis represents the Height in feet.

The plane takes off from this point:

[tex]A(0,0)[/tex].

We know that the plane climbs steadily for 30 minutes (which is 0.5 hours) until it reaches 40000 feet. Then, we can identify another point; this is:

[tex]B(0.5,\ 40000)[/tex]

It travels at that altitude for 2 hours (which indicates a horizontal line) and then it begins to descend to land, giving us another point:

[tex]C(2.5\ 40000)[/tex]

This takes 15 minutes (which is 0.25 hours) at a constant rate. Then, we get a final point:

[tex]D(2.75,\ 0)[/tex]

Knowing these points, we can draw the graph (Observe the image attached)

Answer:

The possible dimensions of the region are

52 ft by 16 ft

32 ft by 26 ft

Step-by-step explanation:

Let

x -----> the length of the rectangular region

y ----> the width of the rectangular region

we know that

The perimeter of a rectangle is equal to

[tex]P=2(x+y)[/tex]

Remember that

A kennel owner wants to subdivide  this region into three smaller rectangles of equal  length

so

we also have to take into account the divisions

[tex]P=2(x+y)+2y[/tex]

[tex]P=2(x+2y)[/tex]

we have

[tex]P=168\ ft[/tex]

[tex]168=2(x+2y)[/tex]

simplify

[tex]84=(x+2y)[/tex] -----> [tex]x=84-2y[/tex] -----> equation A

The total area to be enclosed is 832 ft^2

The area is equal to

[tex]A=xy[/tex]

so

[tex]832=xy[/tex] ----> equation B

substitute equation A in equation B

[tex]832=(84-2y)y[/tex]

[tex]832=84y-2y^2[/tex]

[tex]2y^2-84y+832=0[/tex]

Solve the quadratic equation by graphing

The solution are y1=16 ft, y2=26 ft

see the attached figure

For

[tex]y=16\ ft\\x=84-2(16)=52\ ft[/tex]

For

[tex]y=26\ ft\\x=84-2(26)=32\ ft[/tex]

therefore

The possible dimensions of the region are

52 ft by 16 ft

32 ft by 26 ft

Dependent variables, are the values that result from the independent variables

we have the function

[tex]d(t)=50t[/tex]

In this problem

This is a proportional relationship between the variables d and t

The function d(t) represent the dependent variable or the output

The variable t represent the independent variable or input

Answer:

Independent variable

Step-by-step explanation:

Given is a function

[tex]d(t) = 50t[/tex]

We have to find the independent and dependent variable in this equation

In scientific analysis, the independent variable is one which is changed to get some results for tests.  Dependent variable is one which changes according to changes in independent variable

Here we find the term t is independent as it can be changed independently and d(t) can be analysed for various values of t

Thus the dependent variable [tex]d(t)[/tex] a function of t is tested for various values of independent variable t.

The problem:

The function y=2x+2 and y=-x+k intersect at the point (2,6).

Find the value of k.

Step-by-step explanation:

(2,6) is a point contained by both y=2x+2 and y=-x+k.

Let's see if it actually on y=2x+2.

x=2,y=6

y=2x+2

6=2(2)+2

6=4+2

6=6 is true so it (2,6) is on y=2x+2.

Now we want k such that (2,6) is on y=-x+k.

6=-2+k

Add 2 on both sides:

8=k

So k=8.

Answer:

k = 8

Step-by-step explanation:

y = 2x + 2    

y = -x + k

2x + 2  = - x +k

3x = k - 2

x= 2 : k-2= 6

k = 8

Answer:

Height of the bottom seats is 2 meter.

Step-by-step explanation:

It has been given in the question seats are located on a slope having gradient [tex]\frac{1}{2}[/tex]

We have to find the height h of the bottom seats.

Since gradient = [tex]tan\theta=\frac{1}{2}[/tex]

Therefore, from the figure attached,

[tex]tan\theta =\frac{(12-h)}{20}[/tex]

[tex]\frac{1}{2}=\frac{(12-h)}{20}[/tex]

12 - h = [tex]\frac{20}{2}[/tex]

12 - h = 10

h = 12 - 10

h = 2 m

Therefore, height of the bottom seats if 2 m.

Answer:

m = 21/16 or 1.325

Step-by-step explanation:

1. 9m/12 - m/12 = 7/8 (find common denominator)

2. 8m/12 = 7/8 (subtract)

3. 64m = 84 (cross multiply)

4. m = 84/64 (solve for m)

5. m = 21/16 (simplify fraction)

~1.325

The value of m is 21/16 or 1.3125.

Given,

3m/4 - m/12 = 7/8

We have to solve for m step by step.

We have,

3m/4 - m/12 = 7/8

Step 1.

Find LCM between 4 and 12 and make 3m/4 and m/12 into one fraction.

LCM of 4 and 12 = 12

( 3 x 3m - m ) / 12 = 7 / 8

( 9m - m ) / 12 = 7 / 8

8m / 12 = 7 / 8

Step 2.

Multiply both sides by 12.

12 x 8m/12 = 12 x 7/8

8m = ( 12 x 7 ) / 8

8m = 84 / 8

Step 3.

Dividing 8 into both sides.

8m/8 = 84 / (8 x 8)

m = 84 / 64

m = 4 x 21 / 4 x 16

m = 21 / 16 or m = 1.3125

Thus the value of m is 21/16 or 1.3125.
