In the figure below, UX and UV are tangent to the circle centered at 0. The segment XV passes through the center of the
circle. Given that UX= 15.7 and XV = 8.5, find XW.
Help

Answers

Answer:

2.5

Step-by-step explanation:

The computation of the XW is shown below

As triangle UVX is a right angle

So

VU^2 = XU^2 - VX^2

VU^2 = 15.7^2 - 8.5^2

VU^2 = 246.49 - 72.25

VU^2 = 174.24

VU = 13.2

As VU = WX because of same point tangent

NOw XW is

= UX - UW

= 15.7 - 13.2

= 2.5

a customer left a tip of 25$ this is 20% of his bill. whats the price of the bill?

Answers

Answer:

i think 150

Step-by-step explanation:

Answer:  $30.00

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation. For percents, this is always done by simply dividing the percent (in this case 20%) by 100%.So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.

0.20 x $25.00=$5.00.

$25.00 + $5.00 = $30.00.

15j + 12k = 18
5j + 4k = 6

Answers

Using substitution or elimination?

1. multiply the first or second equation by a number that will make one variable 0
For example; if you multiply the bottom equation by “-3”, it will be “-15j-12k=-18”

2. add the two equations together
It will be 15j-15j which equals 0. Additionally, 12k-12k=0. And, 18-18=0

This means that you have 0=0. When this happens, you have infinitely many solutions. Your teacher may only want you to put infinitely many, or they may want you to solve in terms of one of the variables. If it is the latter, let me know and I will help with that.

A cube has a volume 1,000 cubic feet. What is the length of the edge of the cube. SHOW YOUR ANSWER

Answers

Answer:

10ft

Step-by-step explanation:

The length of one side of this cube would be the cube root of 1000 since each of the three dimensions are the same. You could solve this problem with the following equation, where [tex]l[/tex] is the side length.

[tex]l^3[/tex] = 1000

[tex]l[/tex] = [tex]\sqrt[3]{1000}[/tex]

[tex]l[/tex] = 10

So, the side length of the edge of the cube is 10ft.

The zeros of the given function are -3 and 1.

What are zeros of a function?

The zeros of a function, also referred to as roots or x-intercepts, are the x-values at which the value of the function is 0 (f (x) = 0). The zeros of a function can be thought of as the input values that result in an output of 0.

Given is a function f(x) = (x + 3)(x - 1)/(x-2)(x + 2),

We need to find the zeros of the function,

Equate to 0,

(x + 3)(x - 1)/(x-2)(x + 2) = 0

Therefore,

(x + 3)(x - 1) = 0

x+3 = 0 and x-1 = 0

Therefore,

x = -3, x = 1

Hence, the zeros of the given function are -3 and 1.

Add 4x to both sides
1+2x+4x=-8
Simply again
1+6x =-8
Subtract 1
6x= -8-1
6x=-9
Divide both sides by 6
Divide x = -9\6

Step-by-step explanation:

Slope m is defined as m=(y2-y1)/(x2-x1) in this case

m=(218-155)/(22-15)=63/7=9

y=mx+b

y=9x+b, using point (15,155) we can solve for the y intercept b

155=9(15)+b

155=135+b, b=20 so the line is

y=9x+20

In thirty days there will be

A bag contains 21 red marbles, 24 green marbles, and 21 blue marbles. You choose a marble at random
from the bag. What color marble will you most likely choose?

Answers

Given:

A bag contains 21 red marbles, 24 green marbles, and 21 blue marbles.

To find:

What color marble will you most likely choose if you choose a marble at random from the bag.

Solution:

We have,

Number of red marbles = 21

Number of green marbles = 24

Number of blue marbles = 21

Total number of marbles = 21+24+21

                                         = 66

Now,

[tex]P(Red)=\dfrac{21}{66}[/tex]

[tex]P(Green)=\dfrac{24}{66}[/tex]

[tex]P(Blue)=\dfrac{21}{66}[/tex]

The number of green marbles is largest. So, the probability of getting a green marble is largest.

Therefore, you will most likely choose green marble.

how do u solve these?

Answers

Answer:

g' (×)=f

Step-by-step explanation:

g (×)=f×-7

g' (×)= d÷d× (f×-7)

d÷d×(f+g)=d÷d×(f)+d÷d=(g)

g' (×)=d÷d×(f×)-d÷d×(7)

g'(×)=f-d÷d×(7)

g'(×)=f-0
