Answer:
Hey there!
Your answer is c)
Answer:
2√5
Step-by-step explanation:
The triangle that's shown on the page is a special isosceles right triangle with angle measures of 45° - 45° - 90°
Since one of the side length that sees 45° angle measure is 2√5 the other also has to be equal to this value so the answer is 2√5

Step-by-step explanation:
We know that oppostie sides of a rectange have to be equal
therefore
18=10+2x
solve for x
8=2x
x=4
Answer:
The value of x is 4
Step-by-step explanation:
For a given rectangle
Lenght (l) = 2y = 10
Breadth (b) = 10 + 2x = 18
Here,
2y = 10 ...(1)
10 + 2x = 18 ...(2)
Now, For x
10 + 2x = 18
2x = 18 - 10
2x = 8
x = 8/2
x = 4
Thus, The value of x is 4

A principal of $480 earns $108 interest in 5 years . what rate of interest was being paid?
Answer:
4.5%
Step-by-step explanation:
Solving our equation
r = 108 / ( 480 × 5 ) = 0.045
r = 0.045
converting r decimal to a percentage
R = 0.045 * 100 = 4.5%/year
The interest rate required to
accumulate simple interest of $ 108.00
from a principal of $ 480.00
over 5 years is 4.5% per year.

Find the measure of each angle indicated. Round to the nearest tenth.
Answer:
theta = 22.6 degrees
Step-by-step explanation:
Here, we want to find the value of theta
To do this , we use the appropriate trigonometric identity
Let us identify the given sides of the triangle
we have the hypotenuse, which is the longest side of the triangle, given as 13 and the third side called the adjacent, given as 12
The trigonometric identity that relates the hypotenuse to the adjacent is the cosine
Mathematically;
cosine of an angle is the ratio of the adjacent to the hypotenuse
Thus, we have it that;
cos theta = 12/13
theta = arc(cos) 12/13
theta= 22.6

What is the y-coordinate of the solution to the system of equations? 5x-y=25 4x+3y=1
Answer:
The y-coordinate of the solution is thus -5.
Step-by-step explanation:
Rewrite 5x-y=25 4x+3y=1
in a column:
5x-y=25
4x+3y=1
If we want to find the y-coordinate of the solution, we need to eliminate x. Solving the second equation for 4x yieds 4x = 1 - 3y, or
x = (1 - 3y)/4.
If this is inserted into 5x - y = 12, we get:
5(1 - 3y)/4 - y = 25, or (multiplying all terms by 4 to eliminate fractions):
5 - 15y - 4y = 100, or
-19y = 95, which yields y = -5
The y-coordinate of the solution is thus -5.
A boxer punches a sheet of paper in midair and brings it from rest up to a speed of 20m/s in 0.044 S
Complete Question:
A boxer punches a sheet of paper in midair and brings it from rest up to a speed of 20m/s in 0.044 Seconds.
a. what acceleration is imparted to the paper?
b. if the mass of the paper is 0.003 kg, what force does the boxer exert on it?
c. how much force does the paper exert on the boxer?
Answer:
a. Acceleration = 454.55m/s².
b. Force = 1.36N
c. Force = -1.36N
Step-by-step explanation:
Given the following data;
Final velocity = 20m/s
Time = 0.044 seconds.
Since the paper is at rest, we know that it's initial velocity is equal to 0m/s.
a. To find acceleration;
Mathematically, acceleration is given by the equation;
[tex]Acceleration (a) = \frac{final \; velocity - initial \; velocity}{time}[/tex]
Substituting into the equation, we have;
[tex]a = \frac{20 - 0}{0.044}[/tex]
[tex]a = \frac{20}{0.044}[/tex]
Acceleration = 454.55m/s²
b. To find the force exerted by the boxer;
Mass = 0.003kg
Force = mass * acceleration
Force = 0.003 * 454.55
Force = 1.36N
c. To find the force exerted by the paper;
According to Newton's third law of motion which states that, for every action there is an equal and opposite reaction. Therefore, the paper exerts an equal but opposite force on the boxer.
Force = -1.36N
An angle measures 150°. What is the measure of its supplement?
Answer:
The supplement is = 180-150 i.e30
Step-by-step explanation:
Let the another Angle be x then
x + 150° = 180° {being supplementary angles }
x = 180° - 150°
x = 30°

Write down in terms of n, an expression for the nth term
of the following sequences:
a) 12 10 8 6 4
b) 25 20 15 10 5
Answer:
In bold below.
Step-by-step explanation:
a) 12 10 8 6 4
This is an arithmetic sequence with common difference -2.
nth term = a1 + (n - 1)d
= 12 + (n - 1)-2
= 12 -2n + 2
= -2n + 14.
b) 25 20 15 10 5
This is an arithmetic sequence with common difference -5.
nth term = a1 + (n - 1)d
= 25 + (n - 1)-5
= 25 - 5n + 5
= -5n + 30.
you estimate a lion weighs 250 pounds. the actual weight of the lion is 320 pounds. find the percent error. round your answer to the nearest tenth of a percent.
Answer:
21.9%
Step-by-step explanation:
Percent error = amount of error/actual amount
320 - 250 = 70
70/320 (division) = 0.21875
percent = 21.875%
Rounding to nearest tenth = 21.9%
Your answer should be 21.9%, so I hope this helps!
Answer:
22%

I'm struggling plz help
Step-by-step explanation:
the right side of the diagram
9^2 + x^2 = 24^2
81 + x^2 = 576
x^2 = 576 + 81
x^2 = 657
x=√657
the left side of the diagram
9^2 + x^2 = 24^2
81 + x^2 = 576
x^2 = 576 + 81
x^2 = 657
x=√657
tim bought all of the 2 3 over 4 lb packages for a party
How many pounds of meat fid tim buy?
Answer: he bought 1 and 1/2 pounds of meat. (also could be written as 1.5 pounds)
Step-by-step explanation:
We know that Tim bought all of the two 3/4 lb packages for a party.
Then he bought 2 packages. Such that each package has 3/4 lb meat.
Then the total amount of meat that Tim has is equal to 2 times the amount of meat in each package, this is:
Total meat = 2*(3/4 lb) = (6/4 lb)
and we can write 6 = 4 + 2
then:
Total meat = 6/4 lb = (4 + 2)/4 lb = (4/4 + 2/4) lb = (1 + 1/2) lb
So he bought 1 and 1/2 pounds of meat. (also could be written as 1.5 pounds)
