What is triangle?
A shape with corners and three vertices is called a triangle. It is one of the most fundamental geometric shapes. Triangle ABC is the designation for a triangle containing vertices A, B, & C. In Euclidean geometry, all three points that are not collinear produce a singular triangle and a singular plane.The perimeter of ΔMUD= 38cm
MU=DU=14cm
∠U=36°

41.4 is what percent of 92?
Answer: 45
41.4 is 45 percent of 92
Answer: 45%
Step-by-step explanation:
Solution for 41.4 is what percent of 92:
41.4:92*100 =
(41.4*100):92 =
4140:92 = 45
Now we have: 41.4 is what percent of 92 = 45
Question: 41.4 is what percent of 92?
Percentage solution with steps:
Step 1: We make the assumption that 92 is 100% since it is our output value.
Step 2: We next represent the value we seek with x.
Step 3: 100%=92.
Step 4: In the same vein, x%=41.4.
Step 5: This gives us a pair of simple equations:
$100%=92(1).
$x%=41.4(2).
Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have
100%/x%= 92/41.4
Step 7: Taking the inverse (or reciprocal) of both sides yields
x%/100% = 41.4/92
-> x=45%
Therefore, 41.4 is 45% of 92.

express y in terms of x: 6(x-y) = 19
Expressing y in terms of x gives y = x - 19/ 6
What is subject of formulaSubject of formula can be defined as the variable that is being expressed in terms of other variables in an equation, function or expression.
It is also described as the variable that is being worked out in an expression or equation.
It is made to stand alone on on side of the equality sign.
We have the equation;
6(x-y) = 19
To make 'y' the subject of formula, let's take the following steps;
Divide both sides by 6, we have;
x - y = 19/ 6
now, take the variable 'x' over the equality sign
-y = 19/ 6 - x
Divide both sides by -1
y = x - 19/ 6
Hence, the equation is y = x - 19/ 6

In survey, 9 out of 11 doctors recommended a certain medicine. If 88 doctors were surveyed, how many doctors recommended the medicine? please answer this asap
Answer:
72 doctors recommended the medicine
Step-by-step explanation:
9 out of 11 doctors recommended the medicine, making it 9/11 there are 88 doctors in total 9/11 doctors out of 88 doctors recommended the medicineso, this becomes multiplication. 9/11*88/1 you get 723×(9-4)³ - 46×3
A) 1
B) 237
C) 711
D) 987
Answer:
237
Step-by-step explanation:
3×(9-4)³ - 46×3
subtract 4 from 9 to get 5
3x5³-46x3
calculate 5 to the power of 3 and get 125
3x125-46x3
multiply 3 and 125 to get 375.
375-46x3
Multiply 46 and 3 to get 138
375-138
subtract 138 from 375 to get 237.
And there's your answer
You can follow the rule of BODMAS.
BODMAS stands for Bracket, Of, Division, Multiplication, Addition, Subtraction
By following the rule of BODMAS, the solution will be like this:
3×(5)³ - 46×3

Round to the nearest whole number.
A. 134,360 hits
B. 27,348 hits
C. 41,651 hits

(1.7.5): The value after one year.y-intercept of 10: starting value.12. The number of hits 3 weeks from now will be of 27,348, hence option B is correct.
What is an exponential function?An exponential function is modeled according to the rule given next:
[tex]y = ab^x[/tex]
The parameters of the exponential function are defined as follows:
a is the y-intercept, which is the numeric value of the function when x = 0.b is the rate of change of the function.For item 6, considering the points (0,10) and (1,7.5), the parameters are given as follows:
y-intercept of 10, which is the starting value.When x = 1, y = 7.5, given the value after one year.For item 12, the initial amount and the rate of change are given as follows:
a = 34,000, b = 1 - 0.07 = 0.93.
Hence the number of hits x weeks from now is modeled according to the following function:
[tex]h(x) = 34000(0.93)^x[/tex]
After 3 weeks, x = 3, hence the number of hits will be of:

The owner of a frozen yogurt stand considers different pricing options for a serving of yogurt plus toppings. For what number of toppings do the two options give the same price?
A. Define the variables.
B. Write a system of equations that models this situation.
C. Graph the system. What is the intersection point?
D. What is the solution of the problem?
E. Is the solution reasonable for this situation? Explain.
Answer:
Step-by-step explanation:
A, B: Define the Variables and Write Equations
Let T be the number of toppings.
Option 1: $3 + $0.75*T
Option 2: $4 + $0.50*T
C. Graph the System
See the attached graph. The intersection point is (4,6). This means that 4 toppings will result in a cost of $6 for both yogurt options.
D. Solution to the Problem
The solution is given above, but we can also solve using equations, instead of graphing. We want the value of T that will make these expressions equal:
$3 + $0.75*T = $4 + $0.50*T
$0.25*T = $1
T = 4 toppings
=============
CHECK:
For 4 toppings:
Option 1: $3 + $0.75*T
$3 + $0.75*(4)
$3 + $3 = $6
Option 2: $4 + $0.50*T
$4 + $0.50*(4)
$4 + $2 = $6
Four toppings will make both options equal in cost.
E: Is the solution reasonable?
Yes. The cheaper option ($3) has a more expensive topping, so at some point (at 4 toppings) it will be the same price as the second option, with a higher initial price, but with cheaper toppings.

Determine the y-value of each ordered pair based on the given x-value
y= -x + 9; (-9, ), (1, ), (5, )
Brainfiy to correct person
The value of y in each case are 18,8 and 4 respectively.
Given equation:-
y = -x + 9
Values of x = {-9, 1, 5}
We have to find the corresponding values of y for each value of x.
Putting x = -9 in the given equation, we get,
y = -(-9) + 9 = 9 + 9 = 18
Putting x = 1 in the given equation, we get,
y = -1 + 9 = 8
Putting x = 5 in the given equation, we get,
y = -5 + 9 = 4
Hence, the values of y are {18, 8,4}

3748 from it. If the amount deposited is a positive integer. How will you represent
the amount withdrawn and also find the balance amount in the account?
If the amount deposited is a positive integer , so the amount withdrawn is represented by -3748 and the balance amount in the Manvita's account is Rs 1252 .
In the question ,
it is given that
Money deposited by Manvita = Rs 5000 .
Money withdrawn by Manvita = Rs 3748 .
Since , amount deposited is a positive integer ,
So, the amount withdrawn will be a negative integer
Balance in Manvita's account = Money deposited + Money Withdrawn
Substituting the values , we get
Balance in Manvita's account = 5000 + (-3748)
= 5000 - 3748
= 1252

A particular bacterium population is found to double the in 20 minutes. If a laboratory culture
begins with a population of P=340 of this bacteria and there is no change in the growth rate, how
many bacteria will be present in t=37 minutes?
Hint: Use equation P = Poekt, where k is the relative growth. Round to two decimal places.
The bacteria present at t=37 minutes is found to be 8.40, with no change in growth rate.
What does population growth exponentially mean?When a population's per capita growth rate remains constant, regardless of population size, exponential growth occurs, causing the population to grow exponentially as the population increases.
Given:
P = 340
It has been discovered that a specific bacterial population doubles in 20 minutes.
k = 2/20 = 0.1
t = 37 minutes
We know that,
P = P₀[tex]e^{kt}[/tex]
340 = P₀([tex]e^{0.1*37}[/tex])
340 =P₀(40.44)
P₀ = 8.40
