Answer:
Yes they are congruent and it is explained below
Step-by-step explanation:
There are 5 postulates when testing for congruency and they are;
SSS, SAS, ASA, AAS and HL.
S represents side
A represents angle
H represents hypotenuse
L represents leg
Now, in this our question, we can see that the 3 angles and the three sides of both triangles are equal to each other.
Thus, we can make use of SSS postulate whereby we say the 3 sides of the first triangle are equal to the 3 sides of the second triangle.
Thus, they are congruent.

For what values of x is the expression below defined?
x +3 + x1 - x
O A. 35xs1
O B. 3 > XS-1
O C. 3 >x>1
O D. -3 sx< 1
Answers
Answer:
D. - 3 ≤ x < 1
Step-by-step explanation:
The numerator cannot be the square root of a neg. no.
So, x + 3 ≥ 0 or x ≥ -3
The denominator cannot be a neg. no. or 0.
So, 1 - x > 0
1 > x or x < 1
So, altogether - 3 ≤ x < 1
Therefore, D is the correct answer.

Ahmad said that the volume of cone A is half the volume of cone B? Do you agree? Explain
Answers
Answer:
Yes, I agree
Step-by-step explanation:
See attachments for cone
Cone A
[tex]h = 2r[/tex]
Cone B
R = 2r
[tex]h=r[/tex]
The volume of a cone is
[tex]V = \frac{1}{3}\pi r^2h[/tex]
For cone A, we have:
[tex]V = \frac{1}{3}\pi r^2*2r[/tex]
[tex]V_A = \frac{2}{3}\pi r^3[/tex]
For cone B, we have:
[tex]V = \frac{1}{3}\pi *(2r)^2 * r[/tex]
[tex]V = \frac{1}{3}\pi *4r^2 * r[/tex]
[tex]V_B = \frac{4}{3}\pi r^3[/tex]
So, we have:
[tex]V_B = 2 * \frac{2}{3}\pi r^3[/tex]
Substitute [tex]V_A = \frac{2}{3}\pi r^3[/tex]
[tex]V_B = 2 * V_A[/tex]
Make VA the subject
[tex]V_A = \frac{1}{2}V_B[/tex]
Hence, I agree with Ahmad

A circular cardboard piece is needed for the base of a volcano model. The volcano is 46 centimeters tall and has a volume of 800 cubic centimeters. Which equation can be used to find the area of the circular base? 46 = one-third (B) squared (800) 46 = one-third (B) (800) 800 = one-third (B squared) (46) 800 = one-third (B) (46)
Answers
Answer:
800 = 1/3(B)(46)
Step-by-step explanation:
Volume of a cone is [tex]1/3pir^2h[/tex]
we can set up an equation where V = 1/3pir^2h
Knowns :
V = 800
h = 46
Plug the knowns into the equation
800 = 1/3(pir^2)(46)
pir^2 is the area of a circle, which in this case is B
hope this helps
The equation which can be used to find the area of the circular base is 800 = 1/3(πr²)(46)
What is Three dimensional shape?a three dimensional shape can be defined as a solid figure or an object or shape that has three dimensions—length, width, and height.
Given that circular cardboard piece is needed for the base of a volcano model.
The volcano is 46 centimeters tall and has a volume of 800 cubic centimeters.
We have to find the equation which can be used to find the area of the circular base.
Volume of a cone is 1/3πr²h
V= 1/3πr²h
Plug in the values of volume and height in the above formula
V = 800
h = 46
800 = 1/3(πr²)(46)
Hence, the equation which can be used to find the area of the circular base is 800 = 1/3(πr²)(46)

Step-by-step explanation:
Based on the calculations, the number of degrees that the auto-aim feature would adjust the shot is 12°.
How to calculate the angle formed?Based on the triangle attached in the image above, we can deduce the following parameters:
Side AT = 15 m.
Side CA = 50 m.
Side CT = 60 m.
In this scenario, we would apply the cosine trigonometry function by using this mathematical expression:
AT² = CA² + CT² - 2(CA)(CT)COSθ
15² = 50² + 60² - 2(50)(60)COSθ
225 = 2500 + 3600 - 6000COSθ
6000COSθ = 6100 - 225
6000COSθ = 5875
θ = COS⁻¹(5875/6000)
θ = COS⁻¹0.9792
θ = 11.72 ≈ 12°

In ΔMNO, m∠M = 57° and m∠N = 75°. Which list has the sides of ΔMNO in order from shortest to longest?
Answers
Answer:
B. MN, NO, OM
Step-by-step explanation:
Recall: In any triangle, the sides and the angles are related in the following way:
*The largest angle and the longest side are opposite each other
*The medium angle and the mid-sized side are opposite each other
*The smallest angle and the shortest side are opposite each other
In ∆MNO, we are given that
m<M = 57° which is opposite to side NO
m<N = 75° which is opposite to side OM
m<O = 180° - (75° + 57°) (sum of triangle)
m<O = 48° which is opposite to side MN
Therefore, we can write the order of shortest to longest side in relation to their opposite angles as follows:
MN, NO, OM

Answer: (C) 308 cm^2
Step-by-step explanation: Flat surface area is the surface area that is not curved; in this case, it would be the two circular bases. The height is arbitrary as the height is not needed to calculate the area of the bases. The formula for the area of circular bases is πr^2. Let's plug the given values into the formula. (22/7)(7)^2=(22/7)(49)=154. 154 cm^2 is the area of one base. To find the area of both bases, simply multiply the area of one base by two. 154*2 is 308, therefore the answer is (C) 308 cm^2.

The black graph is the graph of y= f(x). Choose the equation for the red graph
which one: a, b, c, d?
Answers
Answer:
Option C.
Step-by-step explanation:
First, let's define the transformations used here:
We can see that the red graph is shifted horizontally to the right, and that is reflected across the x-axis:
Horizontal shift:
For a general function f(x) an horizontal shift of N units is written as:
g(x) = f(x + N)
where:
If N > 0, the shift is to the left
if N < 0 , the shift is to the right.
Reflection across the x-axis.
For a function f(x), a reflection across the x-axis is just written as:
g(x) = -f(x)
So, if here we have a reflection across the x-axis and a horizontal shift of one unit to the right, we would write the equation for the red graph as:
g(x) = -f(x) (only for the reflection)
g(x) = -f(x - 1) (for the reflection and the shift)
Then the graph of the red function is:
y = -f(x - 1)
We can rewrite this as:
y = -1*f(x - 1)
dividing both sides by -1 we get:
y/-1 = f(x - 1)
This is what we can see in option C, so the correct option is C.

What are the coordinates of R on segments QS such that the ratio is 1:2. Q(-6,2) S(5,6)
Answers
Given:
The endpoints of a line segment QS are Q(-6,2) and S(5,6).
Point R divides the line segment QS in 1:2.
To find:
The coordinates of point R.
Solution:
Section formula: If a point divides a line segment in m:n, then the coordinates of that point are:
[tex]Point=\left(\dfrac{mx_2+nx_1}{m+n},\dfrac{my_2+ny_1}{m+n}\right)[/tex]
It is given that the endpoints of a line segment QS are Q(-6,2), S(5,6) and point R divides the line segment QS in 1:2. So, the coordinate of point R are:
[tex]R=\left(\dfrac{1(5)+2(-6)}{1+2},\dfrac{1(6)+2(2)}{1+2}\right)[/tex]
[tex]R=\left(\dfrac{5-12}{3},\dfrac{6+4}{3}\right)[/tex]
[tex]R=\left(\dfrac{-7}{3},\dfrac{10}{3}\right)[/tex]
Therefore, the coordinates of point R are [tex]\left(\dfrac{-7}{3},\dfrac{10}{3}\right)[/tex].
Debbie has 12 blooms on her lemon tree on the first day she thinks to check it. Each day after that, she notices 3 additional blooms. How many blooms does she have after one week?
Answers
Answer:
33 blooms
Step-by-step explanation:
This can be set up by an equation. x represents the number of days and y represents the number of corresponding blooms. y = 3x + 12 is the equation, as 3 is the rate of change and 12 is the initial amount. One week is 7 days, so 7 can be plugged in for x. 21 + 12 = 33, so after one week, Debbie has 33 blooms.
