Answer:
-12y=5y-68 true for all X
Step-by-step explanation:
-3x4y=(4+5y)-72
simplify:
-3x4y=12y
simplify:
(4+5y)-72
remove parentheses:
4+5y-72
subtract the numbers:
4-72= -68
=5y-68
-12y=5y-68
Answer:
the answer would be 4
Step-by-step explanation:
−3(4y)=4+5y−72
−12y=4+5y+−72
−12y=(5y)+(4+−72)(Combine Like Terms)
−12y=5y+−68
−12y=5y−68
Step 2: Subtract 5y from both sides.
−12y−5y = 5y−68−5y
−17y= −68
Step 3: Divide both sides by -17.
−17y -68
------------ = -----------
-17 -17
y = 4

what is the area of a circle with a diameter of 18.2 cm?
use 3.14 for TT and round your final answer to the nearest hundredth.
the area is ___ square cm.
Answer:
260.0234 cm
Step-by-step explanation:
The formula for area of a circle is π r².
Since the radius is half of the diameter, we must divide the diameter by 2.
18.2/2 = 9.1
Next, we must multiply 9.1 x 9.1.
This gives us 82.81
Now we must multiply 82.81 by pi (3.14).
82.81 x 3.14 = 260.0234
Therefore, the area of the circle is 260.0234.

Answer:
0.26 per Hour
Step-by-step explanation:

0.65 is the closest to your question
Find mMK................
Answer:
Approximately mMK is 53 degrees
Step-by-step explanation:
Here, we want to find the length of MK
As we can see, we have a right triangle at LNK
so
let us find the angle at L first
9 is adjacent to the angle at L and also, 15 is the hypotenuse of the angle at L
so the trigonometric identity that connects adjacent to the hypotenuse is the cosine
It is the ratio of the adjacent to the hypotenuse
So;
cos L = 9/15
L = arc cos (9/15)
L = 53.13 degree
Approximately, L = 53 degrees
so now, we want to get the arc length MK
We are to use the angle-arc relationship here
Using this; arc length MK is equal to the measure of L at the center which is 53 degrees

During his NBA career, Larry Bird made approximately 89% of all free throws. Suppose Larry
makes 10 free throws in a row. Assuming each free throw is independent, what is the
probability he will make the next free throw?
(a) 0.11
(b) 0.50
(c) 0.01
(d) 0.89
Answer:
0.89
Step-by-step explanation:
The probability of Larry making the next free throw is, 0.89
What is mean by Probability?The term probability refers to the likelihood of an event occurring. Probability means possibility. It is a branch of mathematics that deals with the occurrence of a random event. The value is expressed from zero to one
Now, we can assume that Larry Bird has a 89% chance of making any given free throw.
Since, each free throw is an independent event, the fact that he made 10 free throws in a row does not affect the probability of him making the next free throw.
Therefore, the probability of Larry making the next free throw is also 89%.
Thus, the probability of Larry making the next free throw is, 0.89

A CD usually sells for $14.00. If the CD is 20% off, and sales tax is 7%, what is the total price of the CD, including tax?
Answer:
the total price of the CD including tax is $11.984
Step-by-step explanation:
The computation of the total price of the CD including tax is shown below:
The Selling price of the CD is $14
CD is 20% off
And, the sales tax rate is 7%
So, the total price of the CD is
= ($14 - $14 × 20%) × (1.07)
= $11.2 × 1.07
= $11.984
Hence, the total price of the CD including tax is $11.984

Step-by-step explanation:
1. Find the are of the entire rectangle:
length x breadth = 38 x 28 = 1064mm^2
2. Find the area of one semicircle
([tex]\pi[/tex]r^2) divided by 2 =( [tex]\pi[/tex] x 14^2)divided by 2 = 98 [tex]\pi[/tex] = 307.8760801... = 307.88 mm^2
3. Multiply the area by 2
307.88 x 2 = 615.75 mm^2. [ The sum of areas of 2 semicicles]
4. Subtract the area of the 2 semicircles from the area rectangle
1064-615.75 = 448.25 (2dp)
