solve for the value of k

Answers

Answer:

k = 42

Step-by-step explanation:

This is a complementary angle, meaning that the angles formed equal 90 degrees. We know it is complementary because the angle is shown was a tiny square, a sign that it is 90 degrees. Thus, the two angles (k+1) and 47 added together must equal 90. So, we can write an equation:

(k+1) + 47 = 90

k + 1 = 43

k = 42.

K=42
So (42+1)=43 2*43=86 (86+4)=90

You have a moving box with a volume of 16 ft3. You know that the box has a length of 2 ft and a height of 4 ft, but you don’t know the width. You need to know all three dimensions to make sure it can fit in the back of the truck. What is the width of the box?
3 ft
4 ft
2 ft
5 ft

Answers

Answer:

2ft

Step-by-step explanation:

The width of the box is 2 ft.

Here,

Volume of box = 16 ft^3

Length of box = 2 ft

Height of box = 4 ft

We have to find the width of box.

What is Volume of box?

The volume of box is defined as, the multiply of length, width, height.

Now,

Volume of box = 16 ft^3

Length of box = 2 ft

Height of box = 4 ft

Since, Volume of box = Length x width x height

Let width of box is x ft.

Volume of box = 2 * x * 4

16 = 8x

x = 2

Hence, The width of the box is 2 ft.

x=7

Step-by-step explanation:

180=25x+5

175=25x

7=x

Answer:

x = 7

Step-by-step explanation:

Now we have to,

→ Find the required value of x.

We know that,

→ Sum of all angles in a line is 180°.

Forming the equation,

→ (13x + 2) + (12x + 3) = 180°

Then the value of x will be,

→ (13x + 2) + (12x + 3) = 180°

→ 13x + 2 + 12x + 3 = 180°

→ (13x + 12x) + (2 + 3) = 180°

→ 25x + 5 = 180°

→ 25x = 180 - 5

→ 25x = 175

→ x = 175/25

→ [ x = 7 ]

Hence, the value of x is 7.

Find the value of YZ

Answers

Answer:

YZ = 44

Step-by-step explanation:

Let the intersection of XW and YZ equal A. For this problem, we can use power of a point in the scenario where two secants intersect in the interior of a circle. We get the equation:

WA * AX = ZA * AY

We can substitute the values we are given to get:

(2x - 6)(21) = (x + 1)(30)

42x - 126 = 30x + 30

12x - 126 = 30

12x = 156

x = 13

Using segment addition postulate, we can say that:

YZ = YA + AZ

And we can plug in what we know from the diagram:

YZ = 30 + x + 1

We can also plug in the value of x, 13

YZ = 30 + 13 + 1 = 44

What is the answer to -12= x -5?

Answers

Answer:

Step-by-step explanation:

-12 = x-5

5-12 = x -5 + 5

-7  = x

there you go :)

Answer:

x = -7

Step-by-step explanation:

1. Write the equation.

-12 = x - 5

2. Since 5 is negative and we want to leave x by itself, add 5 to both sides. Adding 5 with cancel out the -5.

-12 +5 = x -5 +5

3. When you add +5 to -12, the equation you are left with will be:

-7 = x

The x-intercepts of this quadratic function would be (-1, 0) and (4, 0).

Step-by-step explanation:

The x-intercepts of a function are where the graph of the function hits the x-axis on a coordinate plane, meaning the y-coordinate of an x-intercept would always be 0. In this quadratic function's graph, the parabola crosses the x-intercept at two points: (-1, 0) and (4, 0). So that would be the correct answer.
