Which of the following shows two congruent triangles
Answer:
all of them
Step-by-step explanation:
all of them seem to have the same marks
but if u get the question wrong my next bet would be to go with only C because it has the marks on the sides if that makes sense
Hello! :)
Please help me solve this + explain your answer :)
I will indeed give you Brainlst <3
Answer:
A
Step-by-step explanation:
The two triangles are congruent because if each triangle's angles add up 180 degrees, you can deduce that the triangles have atleast two congruent angles.
Triangle RST:
48 + 73 = 121
180 - 121 = 59
Angle R = 59
Angle T = 48
Angle S = 73
59 + 48 + 73 = 180
Triangle ABC:
73 + 59 = 132
180 - 132 = 48
Angle A = 59
Angle B = 73
Angle C = 48
59 + 48 + 73 = 180

PLEASE HELP MEEEE
Answer:
where's the x in the equation?
Answer:
25/12 Therefore, this equation is true: 25/12 = 25/12 If the numerator is greater than or equal to the denominator of a fraction, then it is called an improper fraction. In that case, you could convert it into a whole number or mixed number fraction. 25/12 = 2 1/12. Simplify Fractions.

on the medicine bottle it says 2 grams for a 60 lb person. the child weighs 105 lbs. how much medicine should they get?
Please help fast!!
Answer:
3.5 Grams
Step-by-step
set 2grams/60lbs equal to xgrams/105
x representing the amount of medicine needed for a 105lb child
Then you divide 60 by 105.
60/105=1.75
Now you multiply 2 by 1.75.
2 x 1.75 = 3.5
3.5 is your answer because 105 is 1.75 times more lbs than 60lbs
meaning you would need 1.75 times the amount of 2grams
to determine the value of x, which is 3.5grams

Malik has two pencils. He has four blue pencils and 2 red pencils. What is the radio of red pencils and blue pencils?
Answer: 2:4 or 1:2
You could also write it in a fraction 1/2
Answer:
2:4
Step-by-step explanation:
We know that Malik has 4 blue pencils and 2 red pencils. Therefore, the ratio of red pencils to blue pencils is 2:4.
# of red pencils : # of blue pencils
2 red pencils : 4 blue pencils
2:4

What is mzA? Enter your answer as only a number
Answer:
A = 25
B = 65
Step-by-step explanation:
Remark
I hope you mean what is the size of <A? If not leave a note. If I am correct than A and C are complementary (equal 90o) since B is a right angle.
Solution
2x + 1 + 5x + 5= 90 Combine like terms
7x + 6 = 90 Subtract 6 from both sides
7x = 90-6
7x = 84 Divide by 7
x = 84/7
x = 12
==========================
Now that is not quite the answer.
A = 2x + 1
A = 2*12 + 1
A = 25
B = 5x + 5
B = 5*12 + 5
B = 60 + 5
B = 65

The formula for calculating your credit utilization ratio is pretty straightforward. To figure it out for an individual card, divide your credit card balance by your available credit line.
What you you do is divide the credit card ratio for each one.
For the first card: $2,397 (total on card) divided by 16,000, (the limit) is 0.149, we round that to 0.15. (15%)
For the second card: $1,218 (total on card) divided by 5,500 (the limit) which is 0.221. We round that to 0.22. (22%)

A and B are sets of real numbers defined as follows.A= {z│z > 4}B= {z│z ≤ 9}Write A U B and A ∩ B using interval notation. If the set is empty, write Ø
Answer:
[tex]AnB=(5,6,7,8,9)[/tex]
[tex](AUB)=(5,\infty) U (-\infty,9)[/tex]
Step-by-step explanation:
From the question we are told that
A= {z│z > 4}
B= {z│z ≤ 9}
Generally A&B are assumed to be really integers
therefore
A={5,6,7,8,.....}={z│z > 4}
B=(9,8,7,6.....)={z│z ≤ 9}
a)For [tex]AnB[/tex]
Mathematically the [tex]AnB[/tex] is given as
[tex]AnB[/tex]=[tex]A=(5,6,7,8,9,10......) n B=(9,8,7,6,5,4,3,2,1......)[/tex]
[tex]AnB[/tex]=(5,6,7,8,9)
Therefore the intercept [tex]AnB[/tex] is Given as

Alaina went to the pet store to buy fish for her new 14-gallon fish tank. Each large fish costs $8 and requires 2 gallons
of water. Each small fish costs $3 and requires 0.5 gallon of water. She has $70 to spend on fish at the pet store. Circle
the combination of large and small fish can Alaina purchase for her fish tank?
Answer:
Small fish= 7
Big fish= 21/4 (so she'll get 5 big fish)
Step-by-step explanation:
With the problem, there are two equations, one for the cost, and one for the amount of water. For the first equation, Alaina can spend 70 dollars and the fish cost 8 and 3 dollars so the equation is 70=8b+4s (s for small and b for big). Then for the second equation there are 14 available gallons and the fish require 2 and .5 gallons so 14=2b+0.5s. Then you just solve the system of equations.
The mean undergraduate cost for tuition, fees, room, and board for four-year institutions was $26,489 for a recent academic year. Suppose that the standard deviation is $3204 and that 36 four-year institutions are randomly selected. Find the probability that the sample mean cost for these 36 schools is Less than $25,000
Answer:
0.00265
Step-by-step explanation:
We solve using the z score formula
z = (x-μ)/σ/√n
where
x is the raw score = $25,000
μ is the population mean = $26,489
σ is the population standard deviation = $3204
n = random number of samples = 36
For x < 25,000
z = 25000 - 26489/3204/√36
z = 25000 - 26489/3204/6
z = -1489/534
z = -2.78839
Probability value from Z-Table:
P(x<25000) = 0.0026485
Approximately = 0.00265
The probability that the sample mean cost for these 36 schools is Less than $25,000 is 0.00265
