Will Give Brainliest, Answer ASAP m∠O =
m∠N =
Answer:
∠ O = 61°, ∠ N = 119°
Step-by-step explanation:
In a parallelogram
Consecutive angles are supplementary
Opposite angles are congruent, thus
x + 2x - 3 = 180
3x - 3 = 180 ( add 3 to both sides )
3x = 183 ( divide both sides by 3 )
x = 61°
Thus
∠ O = ∠ M = x = 61°
∠ N = ∠ P = 2x - 3 = 2(61) - 3 = 122 - 3 = 119°

Answer:
[tex]\boxed{ \sf Option \ 4}[/tex]
Step-by-step explanation:
The domain is all possible values for x.
There are no restrictions on x. The domain is all real numbers.
The range are all possible values of F(x) or y.
[tex]F(x)=5^{3(3)}= 1953125[/tex]
[tex]F(x)=5^{3(0)}= 1[/tex]
[tex]F(x)=5^{3(-2)}= 0.000064[/tex]
When the value of x increases, the value of F(x) increases until infinity. When the value of x decreases, the value of F(x) gets closer to 0 but does not equal to 0.
The range is [tex]y>0[/tex]
The coefficient of 3 does not affect the domain and range, as there are no real restrictions.
Arc length practice
Answer:
[tex]\large\boxed{s = 4\pi}[/tex]
Step-by-step explanation:
The arc length is determined by the formula [tex]s=r\theta[/tex], where s is the arc length, r is the radius, and [tex]\theta[/tex] is the value of the central angle (in radian formatting).
By substituting the values for the radius and the central angle, you can solve for the arc length.
[tex]\text{The radius is half of the diameter -} \: \boxed{\frac{4}{2}=2}[/tex].
The central angle is converted to radian form by multiplying the angle in degrees by the fraction of π/180 - 360° * π/180 = 360π/180 = 2π.
Now, substitute the values and solve for s.
s = (2)(2π)
[tex]\large\boxed{s = 4\pi}[/tex]

Evaluate f(x) = 2|x – 5| for f(–5) and f(0).
Question 20 options:
f(–5) = –20, f(0) = –2
f(–5) = 20, f(0) = 10
f(–5) = 10, f(0) = 0
f(–5) = 12, f(0) = 5
Answer:
[tex]\Large \boxed{\mathrm{f(-5) = 20, \ f(0) = 10}}[/tex]
Step-by-step explanation:
The function is given:
f(x) = 2|x - 5|
Solve for f(-5).
x = -5
f(-5) = 2|-5 - 5|
f(-5) = 2|-10|
f(-5) = 2(10) = 20
Solve for f(0).
x = 0
f(-5) = 2|0 - 5|
f(-5) = 2|-5|
f(-5) = 2(5) = 10

If 3sinA+4cosA=5 then find the value of cosA
Answer:
Cos A =1.4
Step-by-step explanation:
3sinA=5-4cosA; square both sides: 9sin^2(A)=25-40cosA+16cos^2(A);
9-9cos^2(A)=25-40cosA+16cos^2(A); 25cos^2(A)-40cosA+16=0=(5cosA-4)^2.
cosA=4/5 so sinA=3/5 (√(1-16/25) and sinA+cosA=7/5=1.4.

A table costs Rs 720 to make. He sells it for Rs 920. What percentage of profit did he earn?
Answer:
27 7/9%
Step-by-step explanation:
Take the selling price and subtract the cost
920 -720 = 200
Divide it by the cost
200/720
.27777777
Change to percent form
27.777777%
27 7/9%
Answer:
profit percentage = 27.8 %Step-by-step explanation:
To find the percentage of profit we use the formula
[tex] \frac{profit}{cost \: \: price \: } \times 100[/tex]
Subtract the cost price from the selling price to obtain the profit
Cost price = Rs 720
Selling price = Rs 920
Profit = Rs 920 - Rs 720 = Rs 200
So the profit percentage is
[tex] \frac{200}{720} \times 100[/tex]
We have the final answer as
profit percentage = 27.8 %Hope this helps you
What’s is the greatest common factor of 100x^2 - 250xy + 75x
Answer:
The greatest common factor of the expression is 25x
Step-by-step explanation:
Here, we are interested in giving the greatest common factor of the expression.
We can do this by factorization till we have no common factors left.
the expression is;
100x^2 -250xy + 75x
we start with the common factor x;
x(100x -250y + 75)
The next thing to do here is to find the greatest common factor of 100,250 and 75.
The greatest common factor here is 25.
Thus, we have;
25x(4x -10y + 3)
There is no more factor to get from the terms in the bracket. This simply means that the terms in the bracket are no longer factorizable
So the greatest common factor we have is 25x

Joan weighs 10 pounds less than her older sister. The average of the two sisters’ weights is 85 pounds. How much does Joan’s older sister weigh?
Answer:
Joan's older sister weighs 90 pounds
Step-by-step explanation:
x = older sister
x - 10 = Joan
(x + (x-10))/2 = 85
2x - 10 = 170
2x = 180
x = 90
Answer:
90 pounds
Step-by-step explanation:
We can set up an equation to find their weights.
Let's start by naming Joan's weight x.
Her sister's weight would then be x+10, since Joan weighs 10 pounds less.
To find the average between 2 numbers, you need to add them together, then divide by 2.
So we can set up the following equation:
(x+x+10)/2=85
Now let's isolate x.
We can first multiply both sides by 2.
x+x+10=170
Combine like terms.
2x+10=170
Subtract 10 from both sides.
2x=160
Subtract both sides by 2.
x=80
Joan weighs 80 pounds.
x+10 is her sister's weight.
80+10=90
Joan's older sister weighs 90 pounds.

A sum of $46875 was lent out at simple interest and at the end of 1 yr 8 month, the total amount was $50000. Find the rate interest per year.
Answer:
4%
Step-by-step explanation:
As indicated in the question, this is a simple interest question.
The formula for Simple Interest =
I = Principal × Rate × Time
In the above question, we were given the following values.
A = Total value / amount of money = $50000
Principal = $46875
Rate = ??
Time = 1 yr and 8 months
= 1 year +(8/12)
Time = 1.6666666667 years
We are asked to solve for the rate interest per year. Hence, the formula to use to solve this question is given as:
r = (1/t)(A/P - 1)
r = (1/1.6666666667)(50000/46875 - 1)
r = 0.04
Converting to percentage, rate = 0.04 × 100 = 4%
Therefore, the rate interest per year is 4%
A researcher performs a hypothesis test to test the claim that for a particular manufacturer, the mean weight of cereal in its 18 ounce boxes is less than 18 ounces. He uses the following hypotheses: H 0: μ = 18 vs H A: μ < 18 and finds a P-value of 0.01. Draw a conclusion about the cereal box weight at a significance level of 0.05.
Answer:
We conclude that the mean weight of cereal in its 18-ounce boxes is less than 18 ounces.
Step-by-step explanation:
We are given that a researcher performs a hypothesis test to test the claim that for a particular manufacturer, the mean weight of cereal in its 18-ounce boxes is less than 18 ounces.
Let [tex]\mu[/tex] = mean weight of cereal in its 18-ounce boxes.
So, Null Hypothesis, [tex]H_0[/tex] : [tex]\mu[/tex] = 18 {mean that the mean weight of cereal in its 18-ounce boxes is equal to 18 ounces}
Alternate Hypothesis, [tex]H_A[/tex] : [tex]\mu[/tex] < 18 {mean that the mean weight of cereal in its 18-ounce boxes is less than 18 ounces}
Also, it is given that the P-value is 0.01 and the level of significance is 0.05.
The decision rule based on the P-value is given by;
If the P-value of our test statistics is less than the level of significance, then we have sufficient evidence to reject our null hypothesis as our test statistics will fall in the rejection region.If the P-value of our test statistics is more than the level of significance, then we have insufficient evidence to reject our null hypothesis as our test statistics will not fall in the rejection region.Here, clearly our P-value is less than the level of significance as 0.01 < 0.05, so we have sufficient evidence to reject our null hypothesis as our test statistics will fall in the rejection region.
Therefore, we conclude that the mean weight of cereal in its 18-ounce boxes is less than 18 ounces.

Line a and t are parallel. What is the value of x?
7x - 48
5x
pls help me
Answer:
x = 24
Step-by-step explanation:
We know that lines s and t are parallel. Then by definition, the two labelled angles, which are same-side angles, are congruent and equal in measure.
Then, we set the expressions equal to each other:
7x - 48 = 5x
Subtract 5x from both sides:
7x - 5x - 48 = 0
2x - 48 = 0
Add 48 to both sides:
2x = 48
Divide by 2:
x = 48/2 = 24
Thus, x = 24.

If it takes B hours to walk a certain distance at the rate of 3 miles per hour, the number of hours it takes to return the same distance at 4 miles per hour is...? Will mark brainlist
Answer:
It will take 0.75B hours for the return leg
Step-by-step explanation:
Here, given that the first leg of the trip was for B hours at 3 miles per hour , we want to calculate the number of hours the return leg will take at 4 miles per hour given that it is the same distance.
Mathematically, we know that ;
Distance = speed * time
So the distance taken on the first leg of the trip would be;
Distance = 3 miles per hour * B hours = 3B miles
Now, this distance was traveled on the return leg also.
This means that the time taken here will be;
Time on return leg = distance/speed = 3B/4 = 0.75B hours

find whether the following mathematical sentence are constant or variable . 'm' represent the whole numbers between 5 and 7
Answer:
Constant
Step-by-step explanation:
Whole numbers are numbers like 1,2,3 and 4.
1.1,2.3 and Pi arent't whole numbers. Fractions like 3/4 and 5/3 aren't whole numbers.
The whole numbers starting from 5 to 7 are:
● 5, 6 and 7
You can see that we have only one whole number between 5 and 7 wich is 6.
So m has only one value (m=6).
=> m is a constant
PLEASE help me with this question! No nonsense answers please. This is really urgent.
Answer:
last option
Step-by-step explanation:
Let's call the original angle x° and the radius of the circle y. The area of the original sector would be x / 360 * πy². The new angle, which is a 40% increase from x, can be represented as 1.4x so the area of the new sector is 1.4x / 360 * πy². Now, to find the corresponding change, we can calculate 1.4x / 360 * πy² ÷ x / 360 * πy² = (1.4x / 360 * πy²) * (360 * πy² / x). 360 * πy² cancels out so we're left with 1.4x / x which becomes 1.4, signifying that the area of the sector increases by 40%.
