Answer:
Options (1), (3), (5) and (6)
Step-by-step explanation:
Option (1)
Both the circles M and H are same in shape. Therefore, both are similar.
True
Option (2)
MH = MS = [Radii of a circle]
MH = MO + OH
MH = ME + OH [Since, MO = ME]
MH = 10 + 25 = 35 cm
Area of circle M = πr²
= π(35)²
= 1225π
Area of circle H = π(25)²
= 625π
[tex]\frac{\text{Area of M}}{\text{Area of H}}=\frac{1225\pi }{625\pi }[/tex]
Area of M = 1.96(Area of H)
False
Option 3
OH + MS = 25 + 35
= 60 cm
True
Option 4
m∠HMS = 90°
Can't be figured out with the given informations
False
Option 5
Diameter of circle H = 2(radius)
= 2(25)
= 50 cm
True
Option 6
Circumference of circle S = 2πr
= 2π(ES)
Circumference of circle M = 2π(MS)
Ratio of the circumference of circle S and M = [tex]\frac{2\pi (ES)}{2\pi (MS)}[/tex]
= [tex]\frac{ES}{MS}[/tex]
True.
Options (1), (3), (5) and (6) are correct.

In ΔKLM, l = 26 cm, k = 56 cm and ∠K=22°. Find all possible values of ∠L, to the nearest degree.
Answer:
10 degrees
Step-by-step explanation:
sdfsdfs
The possible value of ∠L in ΔKLM is approximately 22 degrees.
What is geometry?Geometry is the study of two-dimensional and three-dimensional figures such as quadrilaterals, triangles, circles, their sides, and angles.
A square triangle is a diagram made by using the squares and the triangle simultaneously. Here in the image below you can see we can make the square triangle by using one square and three triangles.
To find the possible values of ∠L in triangle ΔKLM, we can use the Law of Cosines, which relates the sides and angles of a triangle:
c² = a²+ b²- 2abcos(C)
Where a, b, and c are the lengths of the sides of the triangle opposite to the angles A, B, and C, respectively.
In our case, we know that:
KL = l = 26 cm (the side opposite to ∠M)
KM = k = 56 cm (the side opposite to ∠L)
∠K = 22° (angle opposite to KL)
To find the length of LM (the side opposite to ∠K), we can use the Law of Cosines:
LM² = KL² + KM^2 - 2KLKMcos(K)
LM² = 26² + 56² - 2(26)(56)cos(22°)
LM ≈ 61.3 cm
Now we can use the Law of Sines, which relates the lengths of the sides and the opposite angles of a triangle:
a/sin(A) = b/sin(B) = c/sin(C)
In our case, we can use this formula to find the value of sin(∠L):
sin(∠L)/KM = sin(∠K)/LM
sin(∠L)/56 = sin(22°)/61.3
sin(∠L) ≈ 0.374
∠L ≈ arcsin(0.374)
∠L ≈ 22° (rounded to the nearest degree)
Therefore, the possible value of ∠L in ΔKLM is approximately 22 degrees.

M mrs. Gallegos Burns 236 calories riding her bike each hour she wants to burn more than 590 calories riding her bike at the same rate which inequality represents all possible values for teeth and number of hours mrs. Vehicles must ride her bike to burn more than 590 calories
Answer: x > 2.5
Step-by-step explanation:
Since Mrs Gallegos burns 236 calories riding her bike each hour and she wants to burn more than 590 calories riding her bike at the same rate, the inequality that will represent the number of hours that she will use will be:
x > 590/236
x > 2.5
She must ride the bike for more than 2 1/2 hours to burn more than 590 calories.

. 3(a - 2) – 4(2a - 3)
Answer:
a = 0.5454545455
Step-by-step explanation:
Simplifying
3(a + 2) + 4(2a + -3) = 0
Reorder the terms:
3(2 + a) + 4(2a + -3) = 0
(2 * 3 + a * 3) + 4(2a + -3) = 0
(6 + 3a) + 4(2a + -3) = 0
Reorder the terms:
6 + 3a + 4(-3 + 2a) = 0
6 + 3a + (-3 * 4 + 2a * 4) = 0
6 + 3a + (-12 + 8a) = 0
Reorder the terms:
6 + -12 + 3a + 8a = 0
Combine like terms: 6 + -12 = -6
-6 + 3a + 8a = 0
Combine like terms: 3a + 8a = 11a
-6 + 11a = 0
Solving
-6 + 11a = 0
A shipping container will be used to transport several 40-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23000 kilograms. Other shipments weighing 7800 kilograms have already been loaded into the container.
The question is incomplete. The complete question is :
A shipping container will be used to transport several 40-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 23000 kilograms. Other shipments weighing 7800 kilograms have already been loaded into the container. Which inequality can be used to determine cc, the greatest number of 80-kilogram crates that can be loaded onto the shipping container?
Solution :
Given data :
Weight of the crate = 40 kg
Greatest weight that the container can load = 23000 kg
Weight of the other shipments on the container = 7800 kg
So the greatest number of 40 kg crates = c
Therefore, the weight of the other shipment + weight of crate x number of crates ≤ greatest weight of the container
7800 + (40 x c) ≤ 23000
7800 + 40c ≤ 23000
40c ≤ 23000 - 7800
40c ≤ 15200
c ≤ 380
Hence, the maximum number of 40 kg crate is 380.

Answer:
a) Only the first one is an identity.
Step-by-step explanation:
1). 8 cos O tan O csc O = 8 simplifies to:
cos O tan O csc O = 1
cos O * (sin O / cos O) * (1 /sin O)
= cos O sin O / cos O sin O
= 1
So it is identity.
2) 13 sec^2 O/ cos^2 O - tan^2 O / cos^2O
= 13 sec^2 O - tan^2 O / cos^2 O
Now sec^2 O = 1 + tan^2 O, so we have:
(13( 1 + tan^2 O) - tan^2 O) / cos^2 O
= (12 tan^2 O + 13) / cos^2 O
This is not always = 2 so its not an identity.

A(-6,3) B(0,5) C(2,-1)
PLS HURRY I NEED ALL THE STEPS TOO THANK YOU!!!!!
Answer:
See explanartions below
Step-by-step explanation:
Given the coordinates A(-6,3) B(0,5) C(2,-1)
We first need to get the slope of AB, BC and AC
For AB;
A(-6,3) B(0,5)
Mab = 5-3/0-(-6)
Mab = 2/6
Mab = 1/3
For BC;
B(0,5) C(2,-1)
Mbc = -1-5/2-0
Mbc = -6/2
Mc = -3
For AC:
A(-6,3) C(2,-1)
Mac = -1-3/2-(-6)
MAc = -4/8
Mac = -1/2
Taking the product of Mab and Mbc
Mab * Mbc = 1/3 + -3
Mab * Mbc = -1
Since the product of Mab and Mbc is -1, hence AB abd BC are perpendicular showing that one of the angle of triangle ABC is 90 degrees

Using Cramer’s rule, what is the value of x in the solution to the system of linear equations below?

-x-y=-1

b -1
c 1/2
d 2
9514 1404 393
Answer:
d 2
Step-by-step explanation:
The system of equations can be written in augmented matrix form as ...
[tex]\displaystyle\left[\begin{array}{cc|c}-\frac{1}{2}&3&-4\\-1&-1&-1\end{array}\right][/tex]
The value of x found by Cramer's rule is the ratio of two determinants. The numerator is the coefficient matrix with the x-column replaced by the constant column. The denominator is the coefficient matrix.
[tex]\displaystyle x=\frac{\left|\begin{array}{cc}-4&3\\-1&-1\end{array}\right| }{\left|\begin{array}{cc}-\frac{1}{2}&3\\-1&-1\end{array}\right|}=\frac{(-4)(-1)-(-1)(3)}{(-\frac{1}{2})(-1)-(-1)(3)}=\frac{4+3}{\frac{1}{2}+3}\\\\\boxed{x=2}[/tex]
Using the Cramer's rule, the value of x in the system of equation is 2
How to solve for x?The system of equation is given as:
-1/2x + 3y = -4
-x - y = -1
Represent the above equation as a matrix
[tex]\left[\begin{array}{cc}-1/2&3\\-1&-1\end{array}\right] \left[\begin{array}{c}-4&-1\end{array}\right][/tex]
Start by calculating the determinant of the matrix
|A| = -1/2 * -1 - 3 * -1
Evaluate
|A| = 7/2
To calculate x, we replace the first column by the last.
So, we have:
[tex]\left[\begin{array}{cc}-4&3\\-1&-1\end{array}\right][/tex]
Next, calculate the determinant of the matrix
|x| = -4 * -1 - 3 * -1
|x| = 7
The value of x is then calculated as:
x = |x|/|A|
This gives
x = 7 ÷ 7/2
Evaluate
x = 2
Hence, the value of x is 2

Write an equivalent expression for l + w + l +w
Please help am gonna get an F
Answer:
2w + 2L is the answer I think, but see the discussion below.
Step-by-step explanation:
There are three possibilities.
One
| = 1
so you get 1 + w + 1 + w = 2 + 2w
Two
l = L
l + w + l + w
So you get 2l + 2w. Since the l is so confusing, I normally use L for l. It's not very pretty but it does work
In this instance, you would get 2L + 2w
Three
| could be an absolute value signal. If that is the case, you should use abs(+w+)
Of the three, I think two is what you intended.

miles per hour? how many miles will the cyclist travel in 5 hours? in your
computations assume that 1 mile is equal to 1.6 kiolmeters. Do not round your
answers
Answer:
rate is 8 miles per hour and he travels 40 miles per 5 hours
Step-by-step explanation:
The story problem told that i should assume that 1 mile is 1.6 km
so 5km/hr is equal to 8m/h
i got it by multiplying 5 by 1.6 so i can change from the unit km to mile
so about the miles per 5 hours just multiply the 8 mph by 5 so it is 40
40miles per 5hrs
