Answer:
8
Step-by-step explanation:
Let us assume the following things
x be no of 5 rupees coins
y be no of 2 rupees coins
z be no of 1 rupees coins
Now accoridng to the question
5x + 2y + z = 41
x + y + z = 20
y = 3x
Now do the elimination of variables
So,
4x + y = 21
7x= 21
x = 3
y = 9
z= 8
hence, the 1-rupee coin would be 8

Use the table to write a proportion.
Answer:
One proportion is 15 songs / 2.5 hours = 18 songs / h hours.
ok I'll try to answer
first the given 15/2.5=18/h
so the second hour is missing so we have to multiply cross then the result will be
15h=45
divide 15 for 15 and we got h
again divide 45 for 15
[h=3]

WILL GIVE BRAINLEST!!!!!! Which system of equations can be solved using this matrix equation?
Answer:
b
Step-by-step explanation:
Answer:
A
Step-by-step explanation:
Matrix notation can be confusing, but it's important to remember that systems of equations are typically written as follows:
#x + #y + #z = #
so if there was only one equation it would be written like this:
[tex]\left[\begin{array}{ccc}5&2&1\end{array}\right] \left[\begin{array}{ccc}x\\y\\z\end{array}\right] = [16]\\\\5x + 2y + z = 16\\[/tex]
Then just follow the same pattern for the remaining equations

According to a recent study, the mean number of hours college students spent playing video games per month was 22 hours with a population standard deviation of 2 hours. Two weeks before final exams were scheduled to begin, 100 college students were randomly selected. What is the probability that the mean number of hours spent playing video games is less than 21.8 hours
Answer:
0.15866
Step-by-step explanation:
Given that:
Mean, m = 22
Standard deviation, s = 2
Sample size, n = 100
P(x < 21.8):
Obtain the Zscore ;
Z = (x - m) ÷s/sqrt(n)
Z = (21.8 - 22) ÷ 2/sqrt(100)
Z = - 0. 2 ÷ 0.2
Z = - 1
P(Z < - 1)
From Z probability calculator :
P(Z < - 1) = 0.15866
Hence, Probability of obtaining a score less than. 21.8 is 0.15866
Answer:
ux=22
sdx=0.2
p(x<21.8)=0.159

The following quadrilateral is a parallelogram. Solve for x, y, and z.
Answer:
x= 29°
y= 73°
z= 102°
Step-by-step explanation:
x is on the opposite side of the 29° which means it is equal to 29°
In order to find y we can add 29°+78° and subtract it from 180° since all triangles add up to 180°.
This makes y = 73°
In order to find z, we can subtract 78 from 180 since all straight lines are 180 degrees.
This makes z = 102°

What is the vertex of the parabola
Answer:
lallalalaal hiiiiii
Step-by-step explanation:
The standard form is written as y = ax ^2 + b + c
Using the given equation:
A = -5, b = 30 and c = 7
The x value of the vertex = -b/ 2/a = -30/2(-5) = -30/-10 = 3
To find the y value replace x with the x value and solve for y:
Y = -5(3)^2 + 30(3) + 7
Y = -45 + 90 + 7
Y = 52
The vertex is (3,52)

Answer:
6.4 in is the answer.
Step-by-step explanation:
a = 5 in
b = 4 in
c = ?
According to the Pythagorean theorem,
a² + b² = c²
5² + 4² = c²
25 + 16 = c²
c² = 41
c = 6.403
Round to the nearest tenth,
c = 6.4 in
∴ the length of the pencil is 6.4 in
A car travels a distance of 190 miles in 4
hours and 45 minutes.
Work out the average speed of the car, in
miles per hour.
Answer:
Speed = 40 miles/hourStep-by-step explanation:
Distance (d) = 190 miles
Time (t) = 4 hr 45 min = 19 / 4 hours
Speed = distance / time
= 190 / (19/4)
= 40 miles/hour
The average speed is the total distance traveled by the object in a particular time interval.
The average speed of the car in miles per hour is 40 miles per hour.
What is an average speed?The average speed is the total distance traveled by the object in a particular time interval.
We have,
Distance traveled in 4 hours and 45 minutes = 190 miles
Time = 4 hours and 45 minutes
This can be written in hours as:
= 4.75 hours
Average speed:
= Total distance / Total time
= 190 miles / 4.75 hours
Divide both the numerator and denominator by 4.75
= (190/4.75) / (4.75/4.75)
= 40 miles / 1 hour
Thus the average speed of the car in miles per hour is 40 miles per hour.

what sum of money amounts to rupees 8700 in 3 years at the rate of 24 % per annum
Given:
Amount = 8700
Time = 3 years
Rate of interest = 24% per annum
To find:
The principal values.
Solution:
Formula for amount:
[tex]A=P\left(1+\dfrac{r}{100}\right)^t[/tex]
Where, A is amount, P is principal, r is the rate of interest and t is the number of years.
Putting [tex]A=8700,r=24,t=3[/tex], we get
[tex]8700=P\left(1+\dfrac{24}{100}\right)^{3}[/tex]
[tex]8700=P\left(1+0.24\right)^{3}[/tex]
[tex]8700=P\left(1.24\right)^{3}[/tex]
[tex]8700=1.906624P[/tex]
Divide both sides by 1.906624.
[tex]\dfrac{8700}{1.906624}=P[/tex]
[tex]4563.0391729=P[/tex]
[tex]P\approx 4563.04[/tex]
Therefore, the principal value is about 4563.04.
