Answer:

[tex]Total = 104\ hrs[/tex]

Step-by-step explanation:

Given

[tex]Monday = 15\ hrs[/tex]

[tex]Tuesday = 13\ hrs[/tex]

[tex]Wednesday = 24\ hrs[/tex]

Required

Determine the hours of practice over 6 days

First, we calculate the hours for the given 3 days.

[tex]Hours = Monday + Tuesday + Wednesday[/tex]

[tex]Hours = 15\ hrs + 13\ hrs + 24\ hrs[/tex]

[tex]Hours = 52\ hrs[/tex]

The hours of practice for the other three days is also 52 hours.

So, the total is:

[tex]Total = 52\ hrs + 52\ hrs[/tex]

[tex]Total = 104\ hrs[/tex]

Answer:

x = 105 degrees

Step-by-step explanation:

First, figure out the interior angle, we can do this ading the two angles and then subtracting the sum from 180 (since the interior angle of a triangle adds up to 180 degrees)

180 - (55 + 50) = 75

next, we can figure out x by taking the sum (75) and subtracting that from 180 since it is a supplementary angle:

180 - 75 = 105

x = 105

Answer:

105 degrees!

Step-by-step explanation:

all the angles in a triangle must add to 180.

50+55= 105

therefore, the missing angle would be 75

x+75 must also add to 180 so the answer would be: 105 because 75+105= 180

Hope this helps!!

Answer:1. Use substitution to solve the system of equations:

   -x + 2y=7

    x - 3y = 3

2. Solve the system of equations by the elimination method

a.  2x+ y = -17

   x - y = 2

b. 3x + y = -15

  x + 2y = -10

Answer:

(0, 1)

Step-by-step explanation:

You can solve this by using the substitution or elimination method. For this problem, I'm going to use the substitution method. First, rewrite -4x-2y=-2 in slope-intercept form, which would be y=-2x+1. Substitute the y value in -9x+3y=3 (which would be -9x+3(-2x+1)=3) and solve.

-9x+3(-2x+1)=3

-9x-6x+3=3

-15x=0

x=0

Now, substitute the x value in for the x in any equation. You can do -4(0)-2y=-2 or -9(0)+3y=3. I'm going to use -9(0)+3y=3.

-9(0)+3y=3

3y=3

y=1

Answer:

21.5cm²

Step-by-step explanation:

First you find out the Area of the square itself which is 100cm² (squared). Then you Find the Area of the circle. The formula to find the area of a circle is  π  × Radius². So you find the diameter of the circle (which is 10) and divide that by 2 to find the radius. So the radius is 5 but then you need to square 5 which is 25. Then you multiply 25 with pi which is 78.5 so the area of the circle is 78.5cm². Now what you have to do is subtract the area of the square and the area of the circle to find the area of the shaded region. 100-78.5 is 21.5cm ² and that is the answer.

Answer:

6:8 and 8:14

Step-by-step explanation:

Answer:

B. [tex]a = 4\cdot a[/tex] and [tex]b = 7\cdot b[/tex].

Step-by-step explanation:

The Binomial Theorem states that a binomial of the form [tex](a+b)^{n}[/tex], [tex]a, b\in \mathbb{R}[/tex] can be expanded in the following form:

[tex](a+b)^{n} = \Sigma \limits_{i=0}^{n} \frac{n!}{k!\cdot (n-k)!} \cdot a^{n-i}\cdot b^{i}[/tex] (1)

If we have [tex](4\cdot a + 7\cdot b)^{8}[/tex], then [tex]a = 4\cdot a[/tex] and [tex]b = 7\cdot b[/tex]. In a nutshell, correct answer is B.

B
That is the correct answer, hope it helps my dudes!

Answer:

(3,8)

Step-by-step explanation:

THIS IS AN EXAMPLE FOR ANY PROBLEM!!

Get the equation in the form y = ax2 + bx + c.

Calculate -b / 2a. This is the x-coordinate of the vertex.

To find the y-coordinate of the vertex, simply plug the value of -b / 2a into the equation for x and solve for y. This is the y-coordinate of the vertex.

- Good luck!

Answer:

229.41

Step-by-step explanation:

Well you need to multiply 11.3 times 4.5 per each triangle

Also you need to find the base which is a square

So 5.1 times 5.1 which is technically 5.1 squared. You add from there

EQUATION: 4(11.3 x 4.5) + 5.1 squared  

You should get 229.41

Answer:

(4,18); (6,22); (8,26)

Step-by-step explanation:

Plug in the numbers 4, 6, and 8, in for d using the equation.

c=2d+10

c=2(4)+10

c=8+10

c=18

(4,18)

c=2d+10

c=2(6)+10

c=12+10

c=22

(6,22)

c=2d+10

c=2(8)+10

c=16+10

c=26

(8,26)

Answer:

14

18

22

26

Step-by-step explanation:

c = 2d + 10

1st one: substitute 2 for d

c = 2 x 2 + 10

c = 14

2nd one: substitute 4 for d

c = 2 x 4 + 10

c = 18

3rd one: substitute 6 for d

c = 2 x 6 + 10

c = 22

4th one: substitute 8 for d

c = 2 x 8 + 10

c = 26

Answer:

V = 7168π /3  

Step-by-step explanation:

R ( region ) bounded by curves ; y = 6x^2 , y = 28 - x^2

determine the volume of the solid generated when R is revolved about the x-axis

 Volume = 7168π /3    

attached below is the remaining part of the detailed solution to the problem above

Given that :

y = 6x^2----- ( 1 )   ,  y = 28 - x^2 ------ ( 2 )

equate  ( 1 ) and ( 2 )

6x^2 = 28 - x^2

7x^2 = 28

∴ x = √4 = ± 2
