An angle measures 1.2° more than the measure of its complementary angle. what is the measure of each angle?
Answer:
44.4°
Step-by-step explanation:
Two complementary angles add up to 90°. Let's call one of the two x, and the second 90-x (in fact, [tex]x+(90-x) = 90[/tex]).
At this point we can use the second condition: the first angle, plus 1.2°, is equal to the complementary.
[tex]x+1.2=90-x \rightarrow 2x=88.8 \rightarrow x = 44.4[/tex]
2/5x + 4 = 1/5x + 8 what does x equal
Answer:
x=20
Step-by-step explanation:
Answer:
20
Step-by-step explanation:
2/5x + 4 = 1/5x + 8
(subtract 1/5x from both sides)
1/5x + 4 = 8
(subtract 4 from sides)
1/5x = 4
(multiply by 5 from both sides of the equation to isolate x)
x = 20
What is the simplified form of cos ??
Answer:
[tex]\frac{\sqrt{2} }{2\\}[/tex]
Step-by-step explanation:
A triangle has a total of 180° (B is a 90° angle)
Take 180° - 90° to find the angle of A + C which equals 90°
take 90°/2 to get the angle of C which is 45°
and to check that take 45°+45°+90°= 180°
Now...
cos (C)
cos(45°) = [tex]\frac{\sqrt{2} }{2}[/tex] [Answer]

What are all the things dilations do in geometry?
Answer:
A dilation is a transformation that produces an image that is the same shape as the original, but is a different size. A dilation that creates a larger image is called an enlargement. A dilation that creates a smaller image is called a reduction. A dilation stretches or shrinks the original figure.
Write the equation of a line through points (5, 5) and (1, 0) in point-slope form.
Help soon pls :)
Answer:
Step-by-step explanation:
Find the slope of the line between (5,5)and (1,0) using m=(y2-y1)/(x2-x1)
which is the change of y over the change of x.
m=5/4
Use the slope 5/4 and a given point (5,5) to substitute for x1 and y1 in the point-slope form y−y1=m(x−x1), which is derived from the slope equation m=(y2-y1)/(x2-x1)
y-5=5/4*(x-5)
Simplify the equation and keep it in point-slope form y-5=5/4*(x-5)
Solve for y.
y=5x/4-5/4
Reorder terms.
y=5/4 x-5/4
List the equation in different forms.
Slope-intercept form: y=5/4 x-5/4
Point-slope form: y-5=5/4*(x-5)

A Ferris wheel at Kone Island has a diameter of 63 feet.
Which equation can be used to find its circumference, Cin feet?
diameter 63 feet
O C = 63 x II
O C = 31 x II
O C = 2 x II x 63
O C = 2 x II x 31
The circumference of the Ferris wheel is the product of the diameter and [tex]\pi[/tex]
The circumference equation of the Ferris wheel is C =63 * [tex]\pi[/tex]
How to determine the circumference equationThe circumference of a circle, when the diameter is given is calculated using the following equation
C = [tex]\pi[/tex]d
The diameter of the Ferris wheel is given as:
d = 63 feet.
So, we have;
C = [tex]\pi[/tex] * 63
Rewrite as:
C =63 * [tex]\pi[/tex]
Hence, the circumference equation of the Ferris wheel is C =63 * [tex]\pi[/tex]

Answer:
For class A, the test scores were closer togther so that means more students most likely scored the smae score mutiple times. I think this because the box on the box plot is not spread out like class B.
For class B, the scores varied more so the box plot has to be spread out over more values. Because of the box plot, we can see that Class B had the highest test score compared to class A.

Frank traveled 5.3 kilometers from work to home in 30-minutes. Which of the following values is closest to the average speed, in miles per hour?
Frank's average speed is the rate of the distance traveled and the time
Frank's average speed is 6.58 miles per hour
How to determine the average speedThe given parameters are:
Distance = 5.3 kilometers
Time = 30 minutes
The average speed is then calculated as:
Average speed = Distance/Time
Substitute known values
Average speed = 5.3km/30 minutes
Convert time to hours
Average speed = 5.3km/0.5 hour
Convert the distance to miles
Average speed = 3.29 miles/0.5 hour
Evaluate the quotient
Average speed = 6.58 miles per hour
Hence, Frank's average speed is 6.58 miles per hour

1. On her birthday, Shruti bought 2 kg sweets and distributed 1 kg 500 g among her classmates. How much sweets were left with her?
Answer:
500g
Step-by-step explanation:
since she brought 2 kg of sweets, and distributed to her classmates, that means we wil sustract 2 from 1,5 and that will be 0.5 or 500g
I hope I helped you! :)))
Answer:
500g
Step-by-step explanation:
She initially had 2 kg and gave away 1 kg 500 to her classmates
1000 g = 1 kg
500 g = ?
500 g = half a kilogram
So, 1kg 500g is 1.5 kg
So, to get how much sweets were left with her, we subtract 1.5 kg from 2 kg.
2 - 1.5 = 0.5 kg
So, she was left with 0.5 kg or 500g of sweets

What is the result of the construction shown?
A. Angle bisector
B. Copying an angle
C. Copying a line segment
D. Perpendicular bisector
Answer:
Option C: Copying an angle
Step-by-step explanation:
Angle bisector is a line through an angle that will split that angle to 2 equal angles. Thus, option A is wrong as no angle is being split.
Copying an angle involves reproducing a particular angle in another construction. The image shows us that there is an attempt to reproduce the perpendicular angle of 90°. Thus, option B is correct.
Copying a line segment involves creating the exact size of line in another construction. The image doesn't depict that. Thus option C is wrong.
Perpendicular bisector is when we draw a perpendicular line through a horizontal one to divide it into 2 equal parts. This is not the case here. Thus, option D is wrong.
A 499
B 498
C 898
D 500
Answer:
498
Step-by-step explanation:
We will need to use the Pythagorean Theorem.
A^2 + B^2 = C^2
45^2 + B^2 = 500^2
Subtract 45^2
B^2 = 500^2 - 45^2
Simplify
B^2 = 247,975
Take square root so B is alone
B = 497.9708

Starting from the same place, Ryu walks due west and Samantha walks due east.
On the number line, 0 represents their starting point, negative values represent the distance traveled west and positive values represent the distance traveled east. All values are given in feet.
A number line ranging from minus 660 to plus 660. Tick marks are every 60 units. A point labeled Samantha is located at two tick marks to the right of zero. A point labeled Ryu is located at 8 tick marks to the left of zero.
How many feet apart are Ryu and Samantha on the number line?
Enter your answer in the box.
For Samantha, 2 tick marks east is 120 units east because 1 tick is 60 units.
For Ryu, 8 tick marks west is 480 units west because 1 tick is 60 units.
They are walking to form a line. Just add their distances from 0.
120 + 480 = 600.
--------------------------0----------------------------
Ryu: 480 Samantha: 120
480 + 120 = 600.
600 units, or feet.
