35% of the number of students are boys and if number of girls is 416 then find the total number of students and the number of boys
Answers
Answer:
total students = 640
number of boys = 640-416 = 225
Step-by-step explanation:
percentage of girls = 100-35 = 65%
let total number of students be x
100*416/x = 65
41600/x = 65
x= 41600/x

2 The ratio of beans to rice at T. Blancos place is 2 to 3. There are 27 grains answer of rice on the plate. What is the total number of beans and rice on the plate
Answers
Answer: 45
Step-by-step explanation:
From the question, we are informed that the ratio of beans to rice at T.Blancos place is 2 to 3 and that there are 27 grains answer of rice on the plate. The number of beans would be:
= 2/3 × 27
= 18.
Therefore, the total number of beans and rice on the plate will be:
= 27 + 18
= 45
There are 20 students in my class. Each student needs: .2 cups, 2 plates, 1 party hat and a pair of earphones. My teacher has 2 boxes with plates and forks. Each box contains 8 plates and 10 forks. Would this be enough for the 20 students? Account for each plate and cup. Explain your answer.
Answers
Answer:
Simple, no. This would not be enough.
Step-by-step explanation:
This is because you mentioned that there are 20 students and each of them needed 2 plates. So, there would need to be at least 40 plates. Forks seem irrelevant in this question but if the teacher has 8 plates in 1 box and another 8 in the second box, that would sum up to 16 plates that are available. And the fact that the box doesn't even include the other items, should hint the lack of items available for the students.
This question seemed worded differently. But tried my best. :)

Answers
Answer: 22 ft²
Step-by-step explanation:
To find the area of a rectangle, we multiply the length and width. It doesn't matter which is which as we get the same answer in the end.
Given information:
Length = 11 ft
Width = 2 ft
Area = length x width
Area = 11 ft x 2 ft = 22 ft²
You'll notice the unit is feet squared or ft², because feet x feet gives us feet².

The perimeter of a rectangle is 162 inches. what are the dimensions of the rectangle if the length is 7 times than 3 times the width?
Answers
Answer:
3.68 inches × 77.28 inches
Step-by-step explanation:
Given that,
The perimeter of a rectangle is 162 inches.
Let the width is b.
ATQ,
Length = 7 times than 3 times the width
l = 7(3b) = 21b ...(1)
The perimeter of a rectangle is given by :
P = 2(l+b)
Put all the values,
162 = 2(21b+b)
81 = 22b
b = 3.68 inches
Put the value of b in equation (1)
l = 21b
= 21 (3.68)
= 77.28 inches
Hence, the dimensions of the rectangle are 3.68 inches × 77.28 inches
In addition to his weekly salary, Ethan is paid $16 per delivery.
Last week, he made 5 deliveries, and his total pay was $215. Write a linear equation in
slope-intercept form to find Ethan's total weekly pay T if he makes d deliveries. (please help quickly! I WILL MARK BRAINLEST!!)
Answers
Answer:
Step-by-step explanation:
T=16d=135
The linear equation in slope-intercept form to find Ethan's total weekly pay is T = 16d + 135
A linear equation is in the form:
y = mx + b
where m is the slope of the line, b is the y intercept and y, x are variables.
Let T represent the total money paid to Ethan in a week for d deliveries.
Ethan is paid $16 per delivery, hence m = 16.
T = 16d + b
For 5 deliveries, his total pay was $215. Hence when d = 5, T = 215:
215 = 16(5) + b
215 = 80 + b
b = 135
T = 16d + 135
The linear equation in slope-intercept form to find Ethan's total weekly pay is T = 16d + 135

Answers
Answer:

Step-by-step explanation:
just trust
The formula that gives the x-coordinates of the maximum values of
y = cos(x) is kπ for k= 0, 2±, ±4.
Option B is the correct answer.
What are trigonometric identities?There are three commonly used trigonometric identities.
Sin x = Perpendicular / Hypotenuse
Cosec = Hypotenuse / Perpendicular
Cos x = Base / Hypotenuse
Sec x = Hypotenuse / Base
Tan x = Perpendicular / Base
Cot x = Base / Perpendicular
We have,
The formula that gives the x-coordinates of the maximum values for
y = cos(x) is kπ + π/2 or (2k+1)π/2, where k is any integer.
Now,
This formula corresponds to kπ for k= 0, 2±, ±4
where k can take the values 0, 2, -2, 4, -4, etc.
The cosine function oscillates between -1 and 1, with a period of 2π.
The maximum value of the function is 1, which occurs when the argument of the cosine function is an odd multiple of π/2.
This means that the x-coordinates of the maximum values are given by:
x = kπ + π/2, where k is any odd integer
We can simplify this formula by writing k = 2m+1, where m is any integer, to obtain:
x = (2m+1)π/2
This formula covers all the possible values of k, including positive and negative integers.
For example, when m = 0, we get x = π/2, which is the first maximum value of the function.
When m = 1, we get x = 3π/2, which is the second maximum value, and so on. If we allow m to be negative, we get the values of x for the maximum values of the cosine function in the negative direction.
Therefore,
kπ for k= 0, 2±, ±4
which gives the values of k that correspond to the x-coordinates of the maximum values of y = cos(x).

To solve this problem, we can simply use the formula of normal distribution and substitute the values where required.
The value of P(x <= 44) is 0.025 which is option D
ProbabilityGiven the value of the mean, normal distribution and standard deviation, we can calculate where the value lies
Data;
Mean = 50S.D = 3X = 44But we know that
[tex]z = \frac{x- \mu}{\sigma}[/tex]

[tex]z = \frac{x-\mu}{\sigma} \\z = \frac{44-50}{3} =-2[/tex]
Solving this further;
[tex]P(z\leq -2) = \frac{1}{2} - \frac{1}{2}(0.9545)\\p(z\leq -2) = 0.025[/tex]

find a constant of proportionality that creates a direct proportion to x and y
Answers
Answer:
Please check the explanation.
Step-by-step explanation:
We know that when 'y' varies directly with 'x', we get the equation
y ∝ x
y = kx
k = y/x
Here k is called the constant of proportionality.
Taking an example:
For example, let suppose x and y are directly proportional with x = 4 and y = 10.
We can calculate the constant of proportionality using the formula
k = y/x
substitute x = 4, y = 10 in the equation
k = 10/4
k = 2.5
And at x = 5 and y = 12.5
k = y/x
substitute x = 5, y = 12.5 in the equation
k = 12.5/5
k = 2.5
Therefore, we conclude that a constant of proportionality k = 2.5.
