What is the perimeter?
meters
Answer: 20+21+20+21=40+42=82
Step-by-step explanation:
Add up the sides
Multiply by 2
Try:
20+21=41
Multiply by 2:82
Answer:
82 meters
Step-by-step explanation:
to get the perimeter of a rectangle or square you have to add the lengths of all the four sides
P=20+20+21+21
P=2x20+2x21
P=2x(20+21)
P=2x41
P=82
5x + y = 27
- 10x + 7y = -36
what is the x-coordinate?
Answer: Y = 2 X = 5
Step-by-step explanation:
You would get this answer because 5x + y =27 then you would replace the x with 5 and you get 25 then if you turn y into 2 you get 27 which is what you are looking for same for the other problem hope this helps have a good day
Answer:
The answer is x=5
Step-by-step explanation:
9y=18

You drop a ball from a height of 1.5 meters. Each curved path has 74% of the height of the previous path.
a. Write a rule for the sequence using centimeters. The initial height is given by the is term n = 1.
b. What height will the ball be at the top of the sixth path?
1) A(n) = 1.5 • (0.74)^x-1; 0.33cm
2)A(n) = 0.74 • (1.5)^x-1; 5.62cm
3) A(n) = 150•(0.74)^x-1; 33.29cm
4) A(n) = 150 • (74) ^x-1; 332,850,993,600cm
Answer:
[tex](a)\ A(n) = 150 * (0.74)^{n-1[/tex]
[tex](b)\ A(6) = 33.29cm[/tex]
Step-by-step explanation:
Given
[tex]a = 1.5[/tex] --- initial
[tex]b = 74\%[/tex] --- rate
Solving (a): The rule of the sequence
First convert [tex]a = 1.5[/tex] to centimeters
[tex]a = 1.5 * 100[/tex]
[tex]a = 150[/tex]
The equation is then calculated using the following geometric progression formula
[tex]A(n) = ab^{n-1}[/tex]
This gives:
[tex]A(n) = 150 * (74\%)^{n-1}[/tex]
Express percentage as decimal
[tex]A(n) = 150 * (0.74)^{n-1[/tex]
Solving (b): The height on the 6th path
This implies that:
[tex]n = 6[/tex]
So, we have:
[tex]A(6) = 150 * (0.74)^{6-1[/tex]
[tex]A(6) = 150 * (0.74)^5[/tex]
[tex]A(6) = 150 * 0.222[/tex]
[tex]A(6) = 33.3cm[/tex]

Using the identity sin²theta + cos²theta = 1, find the value of tan , to the nearest hundredth, if cos theta = 0.57 and 0 < theta <
π/2
Answer:
tan*=sin*/cos*
sin*=1-(0.57)^2
sin*=0.6751
tan*=0.57/0.6751
=0.844

Ms. Strickland is practicing the piano for an upcoming recital. The table list the number of minutes she practiced in the past few weeks.
a. What is the median number of minutes she practiced?
b.What is the range of the data?
c.What is the mean number of minutes that she practiced?
Answer:
a. 20
b. 32
c. 20.6
Step-by-step explanation:
Median is the middle number- so put the numbers in order from least to greatest, and find the middle number
8, 10, 10, 15, 15, 20, 20, 20, 25, 25, 25, 35, 40
Median is 20
the range is the difference between the largest and the smallest value- 40-8 is 32
Mean is the average- add all the values and divide by the total number of values (13)
268 minutes divided by 13 days
mean is about 20.6 minutes

The National Sleep Foundation recommends that teenagers aged 14 to 17 years old get at least 8 hours of sleep
per night for proper health and wellness.
A statistics class at a large high school suspects that students at their school are getting less than 8 hours of
sleep on average. To test their theory, they randomly sample 42 of these students and ask them how many hours
of sleep they get per night. The mean from the sample is 2 = 7.5 hours.
Here's their alternative hypothesis:
H : The average amount of sleep students at their school get per night is...
What is an appropriate ending to their alternative hypothesis?
Answer:
Less than 8 hours

because the formula for the triangle is 1/2×b×h
and the formula for the rectangle nos l×w and then add those.
Answer:
A = 60yd
Step-by-step explanation:
First "separate" the rectangle and the triangle in your head.
Now calculate the area of the rectangle and then the area of the triangle.
Rectangle: 6*8 = 48
Triangle: (6*4)/2 = 24/2 = 12
Now we add them together:
48 + 12 = 60yd
Enlarge the triangle by scale factor 0.5 using (3, 1)
as the centre of enlargement.
Answer:
(1.5, 0.5)
Step-by-step explanation:
Given the coordinate point (x, y, if it is enlarged by a factor of k, hence the resulting coordinate will be (kx, ky)
Given the coordinate (3,1). If enlarged by a factor of 0.5, the resulting coordinate will be (3*0.5, 1 * 0.5) = (1.5, 0.5)

You have 48 in a yellow ribbon and 64 inches of red ribbon you want to cut the ribbon into pieces of equal length with no leftovers what is the greatest length of pieces that you can make?
Answer:
16 inches
Step-by-step explanation:
To determine the answer, you have to find the greatest common factor (GCF) of 48 and 64. This is 16 because 16 x 3 = 48 and 16 x 4 = 64.

If the value of a in the quadratic function f(x) = ax2 + b3 + cis , the function will:
open down and have a maximum
open down and have a minimum
open up and have a minimum
open up and have a maximum
If the value of a in the quadratic function f(x) = ax² + bx + c is 1/2, the function will: C. open up and have a minimum.
What is the general form of a quadratic function?In Mathematics and Geometry, the general form of a quadratic function can be modeled and represented by using the following quadratic equation;
y = ax² + bx + c
Where:
a and b represents the coefficients of the first and second term in the quadratic function.c represents the constant term.Since the leading coefficient (value of a) in the given quadratic function f(x) = ax² + bx + c is positive 1/2, we can logically deduce that the parabola would open upward. Also, the value of the quadratic function f(x) would be minimum.

Mai says that the equation 2x+2=x+1 has no solution because the left hand side is double the right hand side. Do you agree with Mai? Explain your reasoning.
Answer:
i do
Step-by-step explanation:
the equation would be no solution if the sides are equal numbers with the same slope and do not intersect. if you plug in a random number such as 7 for x you would get 16 = 8. always making the numbers parrallel
