Answer:

Step-by-step explanation:

h=4

g=32

2*32=64

h-2g= -60

Answer:

Given that m = -2 and n = ¾,

m^2 x (n - 1) = (-2)^2 x (3/4 - 1) = 4 x (-1/4) = -1

n^2 - 3/m​ = (3/4)^2 - 3/(-2) = 9/16 + 3/2 = 9/16 + 24/16 = 33/16

Answer: The volume of the pyramid is 99.8 cubic feet.

Step-by-step explanation:

Hi, to answer this question we have to apply the next formulas:

Base area = side length^2 = 5.8^2 = 33.64 ft2

And then:

Volume of a pyramid = 1/3 x base area x height

Replacing with the values given:

V = 1/3 x 33.64 x8.9 =99.8 ft3

The volume of the pyramid is 99.8 cubic feet.

Feel free to ask for more if needed or if you did not understand something.

Step-by-step explanation:

The two angles are equal so

8x-1 = 5x+11

Subtract 5x from each side

8x-5x-1 = 5x-5x+11

3x -1 =11

Add 1 to each side

3x -1+1 = 11+1

3x = 12

Divide by 3

3x/3 = 12/3

x= 4

The picture is how you solve it

Answer:

V =904.7786842 m^3

Step-by-step explanation:

The volume of a sphere is given by

V = 4/3 pi r^3

The diameter is 12 so the radius is  d/2 = 12/2 = 6

V = 4/3 pi 6^3

V = 288 pi

Let pi = 3.14

V =904.32

If we use the pi button

V =904.7786842

Answer: B .128 in^3

Step-by-step explanation:

The question is asking for the volume of the figure  so multiply the length times the width times the height.

v= 8.2 * 4 * 3.9

v= 127.92 which rounds  to 128.

Answer:

The residual value when x = 4 is 0.58

Step-by-step explanation:

The residual value of a fitted function is the difference between the actual value of the data for a given input and the result of the fitted function. On this problem for the actual values, when [tex]x = 4[/tex] we have [tex]y_{data} = 7.3[/tex] , although, for the fitted function on the same value of "x", we have a different value, which is calculated below:

[tex]y(4) = 2.78*4 - 4.4 = 6.72[/tex]

The residual value is:

[tex]\text{residual value} = y_{data} - y_{function} = 7.3 - 6.72 = 0.58[/tex]

The residual value when x = 4 is 0.58

Functions are written in terms of variables.  The residual value when the value of x is 4 is 0.58

Functions are written in terms of variables. Given the following function that represent the data in the table

y = 2.78x – 4.4

If the value of x is 4, the corresponding value of y is expressed as:

y = 2.78(4) – 4.4

y = 11.12 - 4.4

y = 6.72

Determine the residual value

Residual value = 7.3 - 6.72

Residual value = 0.58

Hence the residual value when the value of x is 4 is 0.58

Answer:

it is 80 degrees for first and then 105 degrees for second

Step-by-step explanation:

The measure of ∠BAC is 105°.

Given that, ∠DAC=(x-20)°=25° and ∠DAB=(2x-10)°.

The two angles are said to be adjacent angles when they share the common vertex and side.

Now, ∠DAC=(x-20)°=25°

⇒x=45°

So, ∠DAB=(2x-10)°=80°

Then ∠BAC=∠DAC+∠DAB=25°+80°=105°

Therefore, the measure of ∠BAC is 105°.

Answer:

-0.544m

Step-by-step explanation:

The height of the barnacle is approximately is, 0.657 meters.

Algebra is the study of abstract symbols, while logic is the manipulation of all those ideas.

The acronym PEMDAS stands for Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This approach is used to answer the problem correctly and completely.

We are given that;

Graph y = sin(x)

Boat travel= 7m

Now,

Let y be the height of the barnacle and x be the distance the boat has traveled

i.e, x = 7 meters

to find the height y :

Substitute the value of x =7 meters in [1] we have;

y = sin(7)

≈0.657.

Therefore, by algebra the answer will be 0.657 meters.

Answer:

(3,4)

Step-by-step explanation:

if the original is (-3,4) and its a reflection over a vertical line that's the y-axis, the x would become opposite, which would mean -3 becoming 3.

Given the coordinate of vertex R(-3, 4). If reflected over the y-axis, the resulting coordinate will be (3, 4)

Images that are reflected are mirror images of each other. The coordinate (x, y) reflected over the y-axis will have the resulting coordinate at (-x, y).

Note that reflecting over the y-axis negates the x-coordinate point while the y-coordinate stays the same.

Answer: 35.2

Step-by-step explanation: To estimate 55 percent of 64, you could round the 55 to 50 percent, and just find half of 64, which is 32. After this, because you only have 5 percent left over, you can take the number you got from 50% of 64 and move the decimal over one place to make it 3.2. Just add that number to 32 and you’ll get your answer.

Factor out 2x

2x( 2x^2 +5x -3)

Factor inside the parentheses

2x( 2x-1) (x+3)

Answer:

2x(2x-1)(x+3)

Step-by-step explanation:

4x³ + 10x² - 6x

here 2x is a common factor then we can pull it out:

4x3 + 10x² - 6x = 2x²×(2x) + 5x×(2x) - 3×(2x)

                        = 2x(2x² + 5x - 3)

                        = 2x(2x-1)(x+3)

2x² + 5x - 3 = (2x-1)(x+3) , here you can use the quadratic formula to find the roots.

Answer:

0.05x+0.25y=8.75; the y intercept represents that if she found 0 nickels she must have found 35 quarters.

Step-by-step explanation:

1. Solve for y:

0.25y= 8.75-0.05x (subtract 0.05x on both sides)

y= (8.75-0.05x)/0.25 (divide by 0.25 on both sides)

2. Since the y intercept can be found when x equals 0, plug in 0 for x into the equation.

y=(8.75-0.05(0))/0.25

y= 8.75/0.25

y=35

The ratio of the number of chocolates that contain nuts to the number of chocolates = 1:4

Step-by-step explanation:

The parameters given are;

Proportion of the box of chocolates that contain nuts = 1/5

Proportion of the box of chocolates that do not contain nuts = 1 - 1/5 = 4/5

Therefore, we have in a box of chocolates with five chocolates;

The number of chocolates that contain nuts = 1

The number of chocolates that do not contain nuts = 4

Which gives the ratio of the number of chocolates that contain nuts to the number of chocolates as 1:4.

Answer:

9.6 ounces butter

8 ounces sugar

12 ounces flour

4 eggs

Step-by-step explanation:

I'm going to write them down so it's easier for me to look at.

12 ounces butter

10 ounces sugar

15 ounces flour

5 eggs

Now make a ratio: 12 : 15 = 4 : 5

Apply this to all of the ingredients.

12 * 0.8 = 9.6

10 * 0.8 = 8

15 * 0.8 = 12

5 * 0.8 = 4

Answer:

Below in bold.

Step-by-step explanation:

12 is  12/15 = 4/5 of 15 so you multiply the amounts of each ingredient by 4/5 or 0.8.

Butter: 12 * 0.8 = 9.6 oz.

Sugar:  10 * 0.8 = 8 oz.

Flour:  15 * 0.8 = 12 oz.

Eggs: 5 * 0.8 = 4 eggs.

[tex]Area= 16a^2-40a+25[/tex]

Step-by-step explanation:

given that the side of the square is 4a

The expression for the area can be solved by

1. subtracting 5 from the sides of the square i.e (4a-5)

2. Solving for the area of the square using

[tex]Area= l^2[/tex]

[tex]Area= (4a-5)^2\\Area= (4a-5)(4a-5)\\[/tex]

opening the bracket and expending we have

[tex]Area= 16a^2-20a-20a+25\\Area= 16a^2-40a+25[/tex]

the expression is [tex]Area= 16a^2-40a+25[/tex]

Answer:

  0.1948° in each exterior angle

Step-by-step explanation:

The exterior angle measure is 360° divided by the number of sides. Here, that is 10x, so the exterior angle is ...

  360°/(10x) = 36°/x

The measure of the interior angle is the supplement of the exterior angle, so we have ...

  x -5 = 180 -(36/x)

  x(x -5) = 180x -36 . . multiply by x

  x^2 -185x = -36 . . . . . subtract 180x

  x^2 -185x +8556.25 = -36 +8556.25 . . . . complete the square

  (x -92.5)^2 = 8520.25

  x -92.5 ≈ ±92.3052

  x ≈ 184.8052 or 0.19480

It does not make any sense for the number of sides to be 10·0.1948 = 1.948, so we assume the number of sides is 184.8052·10 = 1848.

Then the number of degrees in each exterior angle is ...

  36°/184.8052 = 0.1948

Answer:

30 degrees.

Step-by-step explanation:

Rotational symmetry is defined as a figure having the same appearance when rotated by a certain angle.

The wheel has 12 "handles." We can use these as reference points when rotating the image.

We also know that we can rotate by a total of 360 degrees. We can say that:

360/12 = 30 degrees.

Each time you rotate the wheel by 30 degrees, the image will end up on another handle (looks the same). This shows rotational symmetry.
