The perimeter of the polygon is_______units.
Answer:
3 units
Step-by-step explanation:
Since the sides are congruent, then
5 - 2x = - 4x + 9 ( add 4x to both sides )
5 + 2x = 9 ( subtract 5 from both sides )
2x = 4 ( divide both sides by 2 )
x = 2
Then
5 - 2x = 5 - 2(2) = 5 - 4 = 1
perimeter = 3 × 1 = 3 units
Convert (4, 3π/2) to rectangular form.
A) (0,4)
B) (0, -4)
C) (-4,0)
D) (4,0)
Answer:
(0, -4)
Step-by-step explanation:
The rectangular form is expressed as;
x = rcos theta
y = rsin theta
Given the coordinate (4, 3π/2)
r = 4
theta = 3π/2
Substitute
x = 4cos3π/2
x = 4cos270
x = 4(0)
x = 0
y= 4sin3π/2
y = 4sin270
y = 4(-1)
y = -4
Hence the required coordinate is (0, -4)
Use equivalent ratios to find the unknown value.
Answer:
66 is equal to K
Step-by-step explanation:
if 4 times 6 equal 24
then 11 time 6 equals 66
in this case, the scale factor is 6.
Have a wonderful day!
Answer:
K = 66
Step-by-step explanation:
[tex]\frac{k}{24} = \frac{11}{4}[/tex]
when taking a look at this, first try to see if you can solve the denominator.
24 to 4 equals 6 meaning you divide k by 6 will be equal to 11
Then 11 x 6 = 66!!

The sum of David and Jacobs age is 39. Two years ago David was four times Jacobs age. How old are three now?
Answer:
David is 30
Jacob is 9
Step-by-step explanation:
The sum of David and Jacobs age is 39
d + j = 39
d = 39 - j
----------------------
Two years ago David was four times Jacobs age
(d - 2) = 4(j - 2)
d - 2 = 4j - 8
d = 4j - 6
---------------------
Set the equations equal
4j - 6 = 39 - j
5j = 45
j = 9
d = 4(9) - 6
d = 30

It says to find the missing side of the triangle⁉️
Hi there!
you can use the Pythageron Therom for this one.
Basically you just need to apply this formula: a^2 + b^2 = c^2
And then find the root of the hypotenuse.
So, 15^2 + 8^2 = the hypotenuse^2
Which equals, 225 + 64 = 289
Square root of 289 = 17
17 is the answer you are looking for!

Can someone help me please I need area and perimeter
Answer:
Perimeter: 29m
Area: 30m
Step-by-step explanation:
Which expression could be used to determine the perimeter of the triangle?
A 9x + 4
B 9(x + 4)
C 13x
D 13(x + 1)
Answer:
A. 9x + 4
Step-by-step explanation:
Perimeter of a triangle = side A + side B + side C
Side A = 2.5x + 3
Side B = x + 6
Side C = 5.5x - 5
Perimeter of a triangle = side A + side B + side C
= (2.5x + 3) + (x + 6) + (5.5x - 5)
= 2.5x + 3 + x + 6 + 5.5x - 5
= 2.5x + x + 5.5x + 3 + 6 - 5
= 9x + 4
Perimeter of a triangle = 9x + 4
The correct answer is A. 9x + 4
Andre can run 2 1/2 miles in 3/4 hour. Find his average speed in miles per hour.
Answer:
3 1/3 miles per hour
Step-by-step explanation:
(5/2 ÷ 3/4) = (s ÷1)
(5/2 ÷ 3/4) = 10/3
10/3 = s/1
cross-multiply:
3s = 10
s = 10/3
s = 3 1/3 miles per hour
Answer:
3 1/3 mph

V [?]ft
IM DESPERATE HELP
Answer:
V=about 900 cubed feet
Step-by-step explanation:
V=pi(5^2)12
V=pi(25)12
V=pi(300)
V is about 900 cubed feet
Brainliest plz?
Answer:
900 ft cubed
Step-by-step explanation:
v=pi*r sqaured* h
The radius is 5 and sqaure 5 to get to 25. Multiply that by pi, which in your case is 3, and you get 25. Then mulitply that by 12, height, and you get your answer is 900.
Lmk if you need more help
Also, to do this on the calulator is easy as well. Just times pi(3 for you) by the raduis twice and then times that by the height. For example, for this question, I just typed in my calculator, 3 times 5 times 5 times 12 and I got 900.
Sorry if this doesn't make sense lol I'm not good at explaining things.

Answer:
C) Each ounce of yogurt increases the cost by $0.37
Step-by-step explanation:
With 0 ounces of yogurt, you have a flat fee of $1.50 for toppings
With 1 ounce of yogurt, you have a total of $0.37(1) + $1.50 = $1.87
With 2 ounces of yogurt, you have a total of $0.37(2) + $1.50 = $2.24
And so on...
Notice that with each ounce of yogurt, the price is increased at a rate of $0.37 per ounce. $1.50 is what you're just starting with, without yogurt. Therefore, option C is correct.
Find the answers to the following:
A. What is slope-intercept form of
an equation?
B. What is the slope of a line?
C. What is the formula for slope?
D. What is the rate of change of
a line?
E. What is the y-intercept of
a line?
F. What is the x-intercept of
a line?
G. What is the point slope formula?
H. What does HOY stand for?
I. What does VUX stand for?
J. If two lines are parallel, what does this mean?
K. If you are told that two lines are perpendicular, what does this mean?
L. What are the similarities between parallel lines?
M. What is the relationship between two lines that are perpendicular?
Answer:
A) y=mx+b
B) The slope of a line is a number that describes both the direction and the steepness of the line. The slope of the line is either increasing, decreasing, horizontal or vertical.
C) m= rise/run =y2-y1/x2-x1
D) A rate of change describes how one quanity changes with respect to the other. The rate of Change for a line is the slope, the rise over run, or the change in y over the change in x.
E)The y-intercept of the line is the value of y where the line crosses the y-axis.
F)The x-intercept of the line is the value of x where the line crosses the x-axis.
G) The point-slope formula is y-y1=m(x-x1)
H)HOY stands for Horizontal line, slope =0, their equations are in the form y= a constant
I)VUX stands for Vertical line, slope =Undefined, their equations are in the form x= a constant
J)If two lines are parallel, this means that the slopes are the same and the y-intercept are different.
K) The slope of perpendicular lines are the negative reciprocals of each other, and a pair of these lines intersects at 90 degrees
L) The similarities between parallel lines are they have the same steepness, or same angle from the horizontal. Since they have the same steepness they have the same slope.
M)The relationship between two lines that are perpendicular intersect at right angles. they are coplanar lines
A rectangle is placed around a semicircle as shown below. The length of the rectangle is 8 cm. Find the area of the shaded region. Use the value 3.14 for at, and do not round your answer. Be sure to include the correct unit in your answer.
PLEASE HELP
Answer:
Area of the shaded region = 6.88 cm²
Step-by-step explanation:
Area of the shaded region = Area of the rectangle - Area of the semicircle
Area of the rectangle = Length × Width
Length of the rectangle = AD = 8 cm
Width of the rectangle = OP = 4 cm [OP, OB and OC are the radii of the circle which are equal in measures]
Area of the rectangle = 8 × 4 = 32 cm²
Area of the semicircle = [tex]\frac{1}{2}\pi r^{2}[/tex]
= [tex]\frac{1}{2}\pi (OP)^{2}[/tex]
= [tex]\frac{1}{2}\pi (4)^{2}[/tex]
= 25.12 cm²
Area of the shaded region = 32 - 25.12
= 6.88 cm²
