There are 60 children in a club. In the club, the ratio of the number of girls to the number of boys is 3:1 3/5 of the girls play a musical instrument. 4/5 of the boys play a musical instrument. What fraction of the 60 children play a musical instrument?
Answer:
3/20
Step-by-step explanation:
There are 60 children in a club. In the club, the ratio of the number of girls to the number of boys is 3:1
Step 1
We find the number of girls and boys
The ratio is given as:
Girls : Boys
3:1
The sum of Proportion = 3 + 1 = 4
The number of girls
= 3/4 × 60 children
= 45 girls
The Number of boys
= 1/4 × 60 children
= 15 boys
Step 2
From the question, we are told:
3/5 of the girls play a musical instrument.
The number of girls that play Instruments is calculated as:
3/5 × Number of girls
= 3/5 × 45 girls
= 27 girls
4/5 of the boys play a musical
instrument.
The number of boys that play Instruments is calculated as:
4/5 × Number of boys
= 4/5 × 15 boys
= 12 boys
Step 3
The fraction of the 60 children that play a musical instrument is calculated as:
Sum of boys and girls that play a musical instrument/ 60 children
= 27 girls + 12 boys/60
= 39/60
= 3/20
The fraction of the 60 children that play a musical instrument is 3/20

Answer:
k=1/4
Step-by-step explanation:
1/4x1=1/4
0x1/4=0
-1x1/4=-1/4
-2x1/4=-1/2
Very easy
Answer:
K=0.25
Step-by-step explanation:
Well the realationship in the problem y=kx. so now we substitute the numbers so that the equation is now -1/2=-2k
-1/2=-2k
-1/2/-2=k
0.25 or 1/4=k
Express 0.00386×10-4 in standard form?(Urgent....Answer if sure)
Answer:
0.000000386
Step-by-step explanation:
what dose this equal 2(5x + 9) = 48
2(5x + 9) = 48
10x + 18 = 48
10x = 48 - 18
10x = 30
x = 30/10
x = 3

Answer:
180 mm^2
Step-by-step explanation:
For the rectangle, you just multiply the sides together. 15x9 equals to 135. The triangle, is a little harder. For the width, you know that the width of the whole shape is 15mm. And one half of it is 9. So the other half must be 6mm. Now you have the width (6) and the length (15) of the triangle. You find the area of it which is 45mm squared. You add up both numbers to get 180.
Write down the 3rd term in the sequence given by: T(n) = 2n² + n
Answer:
T(3) = 21
Step-by-step explanation:
To find the third term, substitute n = 3 into T(n) , that is
T(3) = 2(3)² + 3 = 2(9) + 3 = 18 + 3 = 21
Plz help solve 7 and 8
Answer:
7) 16 sq units
8) L = 22 cm
Step-by-step explanation:
7) A = 1/2h·(sum of bases)
= 1/2(4)(5+3)
= 2(8) or 16 sq units
8) A (trapezoid) = 1/2(7)(10+12)
= 1/2(22)(7)
= 11(7) or 77 sq cm
To find 'l' in triangle:
A = 1/2·L·7
77 = 7L /2
7L = 154
L = 22 cm

Which statement describes the end behavior of the exponential function f(x) = 2x - 3?
A.) For very high x-values, f(x) moves toward positive infinity.
B.) For very high x-values, f(x) moves toward negative infinity.
C.) For very high x-values, f(x) moves toward the horizontal asymptote.
D.) For very low xvalues of x, f(x) moves toward negative infinity.
Answer:
So, the correct answer is that as x gets bigger, f(x) moves towards positive infinity.

Humberly has $24 and they want to buy at least 8 containers of yogurt. Yogurt is packaged in both large and small containers. Large cost $4, and small container cost $2
Answer:
Hence he will be 4 large containers and 4 small containers
Step-by-step explanation:
Given data
Let the number of small containers be x
and the number of large containers be y
x+y= 8---------1
also
2x+4y= 24-----2
the system of equation to solve the problem is
x+y= 8
2x+4y= 24
from 1
x=8-y
put this in 2
2(8-y)+4y= 24
16-2y+4y= 24
2y= 24-16
2y= 8
y= 8/2
y= 4
put y= 4 in 1
x+4=8
x= 8-4
x= 4
Hence he will be 4 large containers and 4 small containers
Taxis usually charge a fee on top of the per-mile charge. In this case, the taxi charges $3 as a set fee and $0.80 per mile traveled. The function y=0.8x+3 is used to represent the total cost of a ride.
Answer:
$12.3
Step-by-step explanation:
Given data
We are given that the function for the charge is expressed as
y=0.8x+3
Where y is the total cost for a ride
X is the distance of the ride
Say x= 12 miles
Hence the total cost of the ride is
Y= 0.8*12+3
Y= 9.6+3
Y= $12.3
Hence a 12 miles Distance will cost $12.3
