The worth of the boat of Maya which goes for 15% deprication this year at the end of the first year of purchase, with the considered purchase price, is $15,589
How to find the percentage from the total value?Suppose the value of which a thing is expressed in percentage is "a'
Suppose the percent that considered thing is of "a" is b%
Then since percent shows per 100 (since cent means 100), thus we will first divide the whole part in 100 parts and then we multiply it with b so that we collect b items per 100 items(that is exactly what b per cent means).
Thus, that thing in number is
[tex]\dfrac{a}{100} \times b[/tex]
Deprecated price = Initial price- amount of deprication
We have:
Initial price = $18,340
And the amount of deprication = 15% of $18,340
= [tex]\dfrac{18340}{100} \times 15 = 2751 \: \rm dollars[/tex]
(as deprication on first year was by 15% of the original price, and we want to know the deprication for the first year only)
Thus, we get:
Depricated price of Maya's boat = $18,340 - $2,751 = $15,589
Thus, the worth of the boat of Maya which goes for 15% deprication this year at the end of the first year of purchase, with the considered purchase price, is $15,589

The market sells 1 dozen bagels
for $7.00. The bagel shop sells
bagels for $0.60 each. Which is
the better buy?
Answer:
market
Step-by-step explanation:
Market
1 dozen bagels = 12 bagels
⇒ Cost per bagel = $7.00 ÷ 12 = $0.58 (nearest cent)
Bagel shop
Cost per bagel = $0.60
As $0.58 < $0.60 the market is a better buy

16/x 45/3 find the value of x round to the nearest tenth
Answer:
x would be equal to 1.1
Step-by-step explanation:
Step 1: Determine the value of x
I assume that the equation looks like this: 16/x = 45/3
Therefore, using the cross multiply method we can do (16*3) = (x*45)
This will give us 48 = 45x
Then we divide both sides by 45 so we can isolate x by itself
45x/45 = 48/45
x = 1.0667
Then we round to the nearest tenth
x = 1.0667
x = 1.1
Answer: x would be equal to 1.1
Answer:
x = 16/15, or (to the nearest tenth) x = 1.1
Step-by-step explanation:
Note: there must be an " = " sign between the two fractions:
16 45
------- = -------
x 3
Also note that 45/3 reduces to 15: 16/x = 15
Multiplying both sides by x yields 16 = 15x, so that x must be x = 16/15 = 1.1
If the sides of a triangle are 8 and 11 in units and the angle between them is 37 degrees, then the length of the third side is: Options :
A 6.1 B 6.4 C 6.7 D 6.9
The question is an illustration of the laws of cosine, the length of the third side is 6.7 units
How to determine the third side?The measure of the third side is calculated using the following law of cosine
a^2 = b^2 + c^2 - 2bc * cos(A)
So, we have:
a^2 = 8^2 + 11^2 - 2 * 8 * 11 * cos(37)
Evaluate the expression
a^2 = 44.44
Take the square root of both sides
a = 6.7
Hence, the length of the third side is 6.7 units

How to find the side length of a similar triangle?In mathematics, two triangles are said to be similar provided that they have the same ratio of corresponding sides and equal pair of corresponding angles.
Now, from the given image, we can see that DE bisects AC into 2 equal parts and by virtue of the concept of similar triangles, we can say that;
DE/BC = 1/2
We are given;
DE = x + 1
BC = 4x - 6
Thus;
(x + 1)/(4x - 6) = 1/2
Cross multiply to get;
2x + 2 = 4x - 6
4x - 2x = 6 + 2
2x = 8
x = 4
That value of x is the missing value required in conclusion.

What is the slope-intercept equation for this line?
--1
y = [?]=x +
Enter the correct
symbol,+ or -.
-2
-3
Answer:
y = -1/2x - 2
Step-by-step explanation:
Slope Intercept form: y=mx+b
You need to find the slope and y-intercept.
(0,-2) is the y-intercept which is the point on the y-axis that is intersected by the linear equation which is our slope line.
Now, we need to find our slope.
*This line is a negative slope*
Starting at our y-intercept [ (0,-2) ] we need to go to a point where the line intersects.
The red dot on the coordinate plane clearly represents it.
(2,-3) is the red point in which we need to go down 1 and over 2 to get there.
So our slope should be -1 / 2
Lastly, write in slope-intercept form:
y = -1/2x - 2
Slope-intercept form that passes through (9, 3) and has a slope of -
Step-by-step explanation:
Let m and c be the slope and y-intercept respectively,
(y-3)/(x-9) = m
y-3 = mx-9m
y= mx - 9m+3
y = mx + 3(1-3m)
What’s the median for 28,30,30,30,30,31,31,31,31,31,31,31,31
Answer:
31
Step-by-step explanation:
The median is the number that we find in the middle of the data.
So if we have a sequence of {1,2,3}
Then 2 is the median
If we have a sequence of {1,2,3,4,5}
Then 3 is the median
We look in the middle of 28,30,30,30,30,31,31,31,31,31,31,31,31
and we find 31 in the middle.
Note:
If the middle is something with 2 terms in the middle like
1,2,3,4
Then the median is the average of the two middle terms which is
(2+3)/2 = 2.5

Standard form of circle equation

Group like terms:
[tex]2x^2-18x+2y^2-10y+7=0[/tex]
Divide by 2:
[tex]x^2-9x+y^2-5y+3.5=0[/tex]
Factor by completing the square for each variable:
[tex](x-4.5)^2-20.25+(y-2.5)^2-6.25+3.5=0[/tex]
Rearrange into standard form:

Answer:

Step-by-step explanation:
Given equation:
3x - 4 = 8To determine the value of "x", we need to isolate the "x" variable and it's coefficient. This can be done by adding 4 to both sides of the equation.
⇒ 3x - 4 + 4 = 8 + 4⇒ 3x = 12The next step in determining the "x" variable is to isolate the coefficient from the "x" variable. This can be done by dividing 3 both sides of the equation.
⇒ 3x/3 = 12/3⇒ x = 4Therefore, the solution (x) is 4.
Find the length of the missing side of the right triangle.
Answer:
b=8
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2+b^2 =c^2 where a and b are the legs and c is the hypotenuse
6^2 + b^2 = 10^2
36+b^2 = 100
Subtract 36 from each side
b^2 = 100-36
b^2 = 64
Take the square root of each side
sqrt(b^2) = sqrt(64)
b = 8
