In the circle above, the measure of angle DHG can be represented by 7x - 7, and the measure of arc DG can be represented by 9x + 21. The measure of arc DG is ___ degrees.
Answer:
[tex]84^{\circ}[/tex]
Step-by-step explanation:
The measure of an inscribed angle is exactly half the measure of the arc it forms. Thus, we have the following equation:
[tex]2(7x-7)=9x+21[/tex]
Solving, we get:
[tex]2(7x-7)=9x+21,\\14x-14=9x+21,\\5x=35,\\x=7[/tex]
Plugging in [tex]x=7[/tex] into [tex]9x+21[/tex]:
[tex]\widehat{DG}=9(7)+21,\\\widehat{DG}=63+21,\\\widehat{DG}=\boxed{84^{\circ}}[/tex]

Answer:
Length = 12 feet, Width = 10 feet
Step-by-step explanation:
Let the length of the bedroom be 'x' ft and the width of the bedroom be 'y' ft.
We know that the perimeter of a rectangle is given by,
P=2(length+width)
P=2(x+y)
It is given that, the length of the bedroom is 2 more than the width, so,
x=y+2
Putting the values in the equation of perimeter we get,
44=2((y+2)+y)
44=2(2y+2)
44/2 =2y+2
22=2y+2
2y=22−2
y= 20/2 =10
Therefore, x=y+2=10+2=12
Hence, the length of the bedroom is 12 feet and the width of the bedroom is 10 feet.
Hunter is making $46,500 per year and gets a 5.5%
increase in pay. Determine how much money
Munter makes after his increase and show your
work
Answer:
$49,057.50
Step-by-step explanation:
To find how much a percent is of a number you multiply that number and that percent then add the two
SO.... 46,500x5.5% is 2557.50 and then you add the 2 so 46,500 + 2557.50= 49,057.50 hope this helps

A rectangle has a length of 3x^2y^3 inches and width of 4x^2y^3 inches . which expression represents the perimeter in inches of rectangle?
Answer:
44x²y³
Step-by-step explanation:
don't see options for answers but the perimeter would be:
2(3x²y³) + 2(4x²·2y³)
= 6x²·2y³ + 8x²·4y³
= 12x²y³ + 32x²y³
= 44x²y³

For some reason, my explination isn't formatting properly, hope this helped
Answer:
Step-by-step explanation:
The angle is 60 degrees so the triangle is half of an equilateral triangle
so y is half of the hypotenuse:
y = 16/2 = 8
x = √16^2 - 8^2 = √256 - 64 = √192 = 8√3
Given that y = 4x + c is a tangent to the function f(3) = 3x^2 - 8x + 6, find the value of c.
a.Find the mean, median, and mode of 14, 15, 3, 15, 14, 14, 18, 15, 8, 16
Given:
The data set is:
14, 15, 3, 15, 14, 14, 18, 15, 8, 16
To find:
The mean, median and mode of the given data set.
Solution:
We have,
14, 15, 3, 15, 14, 14, 18, 15, 8, 16
Arrange the data values in ascending order.
3, 8, 14, 14, 14, 15, 15, 15, 16, 18
Mean of the data set is:
[tex]Mean=\dfrac{\text{Sum of all observations}}{\text{Number of observation}}[/tex]
[tex]Mean=\dfrac{3+8+14+14+14+15+15+15+16+18}{10}[/tex]
[tex]Mean=\dfrac{132}{10}[/tex]
[tex]Mean=13.2[/tex]
The number of observation is 10 which is an even number. So, the median of the data set is:
[tex]Median=\dfrac{(\dfrac{n}{2})\text{th term}+(\dfrac{n}{2}+1)\text{th term}}{2}[/tex]
[tex]Median=\dfrac{(\dfrac{10}{2})\text{th term}+(\dfrac{10}{2}+1)\text{th term}}{2}[/tex]
[tex]Median=\dfrac{5\text{th term}+6\text{th term}}{2}[/tex]
[tex]Median=\dfrac{14+15}{2}[/tex]
[tex]Median=\dfrac{29}{2}[/tex]
[tex]Median=14.5[/tex]
Mode is the most frequent value of the data set.
In the given data set the highest frequency is 3 because 14 and 15 occurs three times.
So, the mode of the given data set is 14 and`15.
Therefore, the mean is 13.2, median is 14.5 and mode is 14 and 15.

function h describes the height of a ball, in inches, after n bounces and is defined by the equation h(n)=120 x (4/5)^n.
What is h(3) ?
What does h(3) represent in this situation?
Answer:
Step-by-step explanation:
h(3) = 120*(4/5)^3, which evaluates to 120(64/125), or 61.64.
What does this mean: After 3 bounces the height of the ball is 61.64 ft.

The cost of 3 loaves of bread and 3 gallons of milk is $19.35. The cost of 4
loaves of bread and 2 gallons of milk is $17.90. How much does one loaf
of bread cost?
Answer:
bread $2.5 milk $3.95
Step-by-step explanation:
b=bread m= milk
3b +3m = 19.35
4b+2m= 17.90
Multiply the first by (-2)
Multiply the second by 3
Then add both
-6b -6m = -38.7
12b+6m=53.7
(when you add both 6m is cancelled)
6b = 15
b= 2.5 (BREAD $2.5)
4(2.5) = 10
10+ 2m = 17.90
2m = 7.90
m= 3.95 (MILK $3.95)
