Compare the triangles and determine whether they be proven congruent, if possible, by SSS, SAS, ASA, AAS, or HL. Write your answer in the box.
Answers
Answer: SSS
========================================================
Explanation:
The sides shown by the single tickmark are the same length. That's one "S" of "SSS".
The sides shown with double tickmarks are the same length. This is another "S" of "SSS".
Lastly, the third unmarked sides of each triangle overlap together perfectly. We consider this a shared side. They are the same length due to the reflexive property. This is the third "S" of "SSS".
The order of the "S" terms mentioned above doesn't matter. All that matters is that we have three pairs of congruent sides. This is enough to use the SSS congruence theorem to prove the two triangles are congruent.
--------------
Extra info:
We don't have any information about the angles, so we cannot use ASA, SAS, or AAS.
We can't use HL because that only applies to right triangles.
Elijah puts $550 in an account earning 8% simple interest annually. What is the total amount of money he will have in his account after 6 years, if no withdrawals or deposits are made?
Answers
Answer:
814?
Step-by-step explanation:
Simple interest is I = PRT, so you can multiply the 550, by 1.08 by 6 to get the total.
The principal is 550, the rate is 0.08 (using 1.08 because the prior gives interest, and using a whole 1 with it will be the total), and the time is 6 years because the interest is simple annual.
use 0.08 instead of 1.08 when solving for interest.
A vendor supplies 32 litres of milk to a hotel in the morning and 68 litres of milk in the evening. If the milk costs Rs 15 per litre, a. Write a numerical expression for the given statement. B. Which property of whole numbers would you use to form a numerical expression for the given statement? C. How much money he gets per day for the supply?
Answers
Answer:
a) (15 × 32) + (15 × 68)
b) Distributive property
c) $1500
Step-by-step explanation:
A vendor supplies 32 litres of milk to a hotel in the morning and 68 litres of milk in the evening. If the milk costs Rs 15 per litre,
a. Write a numerical expression for the given statement.
The numerical expression for the given statement is written as:
$15 × 32 liters + $15 × 68 liters
15 × 32 + 15 × 68
B. Which property of whole numbers would you use to form a numerical expression for the given statement?
The property that I would use to form a numerical expression is a distributive property
a × (b + c) = (ab + ac)
Where a = $15
b = 32 liters
c = 68 liters
Hence:
15 (32 + 68) = (15 × 32) + (15 × 68)
C. How much money he gets per day for the supply?
The amount he gets per day:
15 (32 + 68) = (15 × 32) + (15 × 68)
= $1500

The point P(7, −3) lies on the curve y = 3/(6 − x). (a) If Q is the point (x, 3/(6 − x)), use your calculator to find the slope mPQ of the secant line PQ (correct to six decimal places) for the following values of x. (i) 6.9 mPQ = 1
Answers
Answer:
The right answer is "3.33333".
Step-by-step explanation:
The given points in the question are:
[tex]P=(7,-3) = (x_1,y_1)[/tex]
[tex]Q=(x,\frac{3}{6-x} )=(x_2,y_2)[/tex]
Now,
The slope of PQ will be:
= [tex]\frac{y_2-y_1}{x_2-x_1}[/tex]
By putting the values, we get
= [tex]\frac{\frac{3}{6-x}+3 }{x-7}[/tex]
= [tex]\frac{3+18-3x}{(6-x)(x-7)}[/tex]
= [tex]\frac{21-3x}{(6-x)(x-7)}[/tex]
= [tex]\frac{3(x-7)}{(6-x)(x-7)}[/tex]
= [tex]\frac{3}{x-6}[/tex]
hence,
x = 6.9
it's slope will be:
= [tex]3.33333[/tex]

A stack of 500 pieces of paper is 1.875 inches tall. Compute the thickness of each piece of paper. Show your reasoning.
Answers
Answer:
0.003750 inches
If the thickness of 500 pieces is given as 1.875. the thickness of one sheet of paper can be determined by dividing the total inches by 500
Thickness of each paper = thickness of total paper / 500
1.875 / 500 = 0.003750 inches

A committee of 3 men and 4 women , is to be formed from 5 men and 7 women . How many different committees can be formed if :
A. a particular man must be on the seat
B .two particular must not be on the committee
C. There are no restrictions.
Topic : Permutation and combination
Answers
Answer:
Part A
A particular man on the seat, then 2 men are out of 4:
4C2 = 4!/(4-2)!2! = 4*3*2/2*2 = 6
4 women out of 7:
7C4 = 7!/(7-4)!4! = 7*6*5*4!/3!4! = 35
Total combinations:
6*35 = 210Part B
Option 1. 2 men excluded
3 men out of 3 and 4 women out of 7
Total ways:
7C4 = 35 (as above)
Option 2. 2 women are excluded
3 men out of 5 and 4 women out of 5
5C3*5C4 = 5!/3!(5-3)! * 5!/4!(5-4)! = 5*4/2 * 5/1 = 10
Option 3. 1 man and 1 woman excluded
3 out of 4 men and 5 out of 6 women:
4C3*6C5 = 4!/3!(4-3)! * 6!/5!(6-5)! = 4*6 = 24 Part C
No restrictions, so the number of ways:
3C5 * 7C4 = 5!/3!(5-3)! * 35 = 4*5/2 * 35 = 10*35 = 350
What is the volume of the figure?
Answers
9514 1404 393
Answer:
C. 205.3 units²
Step-by-step explanation:
The volume of the figure is the sum of the volumes of ...
1/2 sphere of radius 2
cylinder of radius 2 and length 12
cone of radius 2 and length 9
The formulas for the volumes of a sphere, cylinder, and cone are ...
V = 4/3πr³ . . . sphere
V = πr²h . . . . cylinder
V = 1/3πr²h . . . cone
Then the sum of the volumes is ...
1/2 sphere + cylinder + cone = (1/2)4/3πr³ +πr²h +1/3πr²h'
where h is the cylinder height and h' is the cone height
= πr²(2/3r + h + 1/3h')
= π(2²)(2/3·2 +12 +1/3·9) = π(4)(16 1/3) = π(65 1/3) ≈ 205.2507
The volume of the figure is about 205.3 units³.

Which similarity statement expresses the relationship between the two triangles?

triangleZYX-triangleACB
triangleZYX-triangleCBA
triangleZYX - triangleABC
Answers
Given:
The figure of two triangles.
To find:
The similarity statement for the given triangles.
Solution:
The corresponding sides of similar triangles are proportional.
In the given triangles,
[tex]\dfrac{XY}{AB}=\dfrac{6}{12}[/tex]
[tex]\dfrac{XY}{AB}=0.5[/tex]
Similarly,
[tex]\dfrac{YZ}{BC}=\dfrac{3}{6}[/tex]
[tex]\dfrac{YZ}{BC}=0.5[/tex]
And,
[tex]\dfrac{XZ}{AC}=\dfrac{7}{14}[/tex]
[tex]\dfrac{XZ}{AC}=0.5[/tex]
Since [tex]\dfrac{XY}{AB}=\dfrac{YZ}{BC}=\dfrac{XZ}{AC}[/tex], therefore
[tex]\Delta XYZ\sim \Delta ABC[/tex]
It can be written as:
[tex]\Delta ZYX\sim \Delta CBA[/tex]
Therefore, the correct option is A.

so because the shape is broken down into right triangles we’ll just use the formula
A = ab/2
and because all of our “a” and “b” are the same
a = 4
b = 3
once we’ve found one triangle
A (one triangle) = 4•3/2
A (one triangle) = 6
we can multiple our answer by 4 to find the total of our whole shape
A = 6•4
A = 24

Which is a prime number 63 , 7, 27, 33
Answers
Answer:
7
Step-by-step explanation:
63 can be divided by 3, 7, 9, 21
27 can be divided by 3, 9
33 can be divided by 3, 11
Answer:
The correct answer is 7.
Step-by-step explanation:
A prime number is a number whose factors only include 1 and that number itself, examples of prime numbers would be 2 (1; 2), 5 (1; 5), and 11 (1; 11). In order to find the prime number, you must calculate all factors in each number. 63 has the following factors: 1; 3; 7; 9; 21; 63, so it isn't a prime number. 27 has the following factors: 1; 3; 9; 27, so it isn't a prime number. 33 has the following factors: 1; 3; 11; 33, so it also isn't a prime number. 7 only has two factors, 1 and 7, meaning that it is a prime number. Hence, this would be the correct answer.

If f(x)=3x+2, find f(-2)
Answers
Answer:
I think that number one is 26, two is -4, and three is -4

To solve for number one replace 8 with (x) so 3(8) + 2. 3 x 8 = 24 and 24+2 = 26
Numbers 2 and 3 appear to be the same problem so just do 3(-2) + 2 (Because you replace the number with the x) 3(-2) = -6 + 2 = -4!

What is the size of the blue angle, and what do we call an angle with these measurements?
Answers
Answers:
The blue angle is 135 degrees
The angle is obtuse
==========================================
Explanation:
Along the inner ring of values, the left arrow points at 135 (the midpoint of 130 and 140). Therefore, the blue angle is 135 degrees. Or you could note that starting at 130, and counting 5 spaces, will get you to 135. You could start at 140, and count down 5 spaces to get to the same spot.
Another way you can get the answer is to note that the blue arrow on the left is pointing at 45 along the top ring of numbers. This adds to 90 to get 90+45 = 135
Either way, you should get to 135 degrees as the angle value.
-------------
The angle is obtuse because the angle is larger than 90 degrees. It's wider or larger than a right angle.
