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: 1/8 x, the second option
Step-by-step explanation:
(5)(1/8)(x) = 5/8 x
(11)(1/8)(x) = 11/8 x
Both have 1/8 * x in common
1/8 * x = 1/8 x
A movie theater charges $4.50 for children and $8.00 for
adults
The next day, the manager announces that she wants to see
them take in $10,000 in tickets. If there are 240 seats in the
house and only five movie showings planned that day, is it
possible to meet that goal?
Answer:
No, the max is $9600.
Step-by-step explanation:
240 x 8=1920.
1920 x 5=$9600.
There are 225 wolves in the state park. The population is increasing at a rate of 15% per year. Make a prediction for how long it will take the population to reach 500.
Answer:
Step-by-step explanation:
F=I(1+r)^t
500=225(1.15^t)
t=ln(500/225)/(ln1.15)
t=5.713 years

At the two points where the curve x² + 2xy + y² = 9 crosses the x-axis, the tangents to the curve are parallel. What is the common slope of these tangents?
Answer:
-1
Step-by-step explanation:
We can find the tangents to the curve at x = 0, where the roots of the function occur (function crosses the x-axis). We can differentiate the function with respect to x by using implicit differentiation.
[tex]\displaystyle \frac{d}{dx} \Big [ x^2 + 2xy + y^2 = 9 \Big ][/tex]We will need to use the Power Rule and Product Rule to differentiate this function.
[tex]\displaystyle 2x + 2 \Big ( x \cdot \frac{dy}{dx} + y \cdot 1 \Big ) + 2y \cdot \frac{dy}{dx} = 0[/tex]Distribute 2 inside the parentheses.
[tex]\displaystyle 2x + 2x \frac{dy}{dx} + 2y + 2y \frac{dy}{dx} = 0[/tex]Move all terms containing dy/dx to the left side of the equation, and all other terms to the right side of the equation.
[tex]\displaystyle 2x \frac{dy}{dx} + 2y \frac{dy}{dx} = -2x-2y[/tex]Factor dy/dx from the left side of the equation.
[tex]\displaystyle \frac{dy}{dx} \Big (2x + 2y \Big ) = -2x-2y[/tex]Divide both sides of the equation by 2x + 2y.
[tex]\displaystyle \frac{dy}{dx} = \frac{-2x-2y}{2x+2y}[/tex]Factor the negative sign out of the numerator.
[tex]\displaystyle \frac{dy}{dx} = -\frac{2x+2y}{2x+2y}[/tex]Cancel out the numerator and the denominator.
[tex]\displaystyle \frac{dy}{dx} = -1[/tex]The derivative of the function is -1 at all points, meaning that everywhere the function has a slope, or tangent, of -1.
The common slope of the tangents as the curve x² + 2xy + y² = 9 crosses the x-axis is -1.
Martha biked 55 miles per day and Enrico biked 145 miles every 3 days. After 6 days, which statement correctly compares the number of miles they each biked
Answer:
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.
Step-by-step explanation:
i. Martha bikes 55 miles per day.
So that after 6 days, Martha would have covered;
55 miles x 6 = 330 miles
After 6 days, Martha would have biked 330 miles.
ii. Enrico bikes 145 miles every 3 days.
Then after 6 days, Enrico would have covered;
[tex]\frac{6 days}{3 days}[/tex] x 145 miles
= 2 x 145 miles
= 290 miles
After 6 days, Enrico would have biked 290 miles.
After 6 days Martha biked 330 miles, while Enrico biked 290 miles.

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.

1 inch = 15 miles. Because there are 3 inches we will need to multiply by 3. 3 x 15= 45
whats the equation to (4,5) , Slope = 5/2
Answer:
y= 5/2x - 5
Step-by-step explanation:
First, use the equation y=mx+b
m = the slope (5/2)
x = the x coordinate: 4
y = the y coordinate: 5
Then plug in for the values and solve for the only unknown, b.
Therefore we have:
5 = (5/2)4 + b
5 = 10 + b
5 - 10 = b
b = -5
Revert to original equation:
y = 5/2x - 5

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

You make a photo prop for a school fair. You cut a 10-inch square out of a parallelogram-shaped piece of wood. What is the area of the photo prop?
The area of the photograph when cropped by 10 square inches is,
31.99 ft².
Use the concept of quadrilateral defined as:
A quadrilateral is a shape with four sides, four vertices, and four angles that is only two-dimensional. Convex and concave are the two main forms. Convex quadrilaterals can also be divided into a number of subgroups, including trapezoids, parallelograms, rectangles, rhombus, and squares.
Given that,
The height of the photo is = 8 ft
The width of the photo is = 4 ft
The cropped area = 10 square inches,
Since we know that,
1 square inch = 0.007 square foot
Therefore,
10 square inches = 0.007 x 10 square foot
10 square inches = 0.07 square foot
The area of the photograph = 8x4
The area of the photograph = 32 square ft
Now the area of the photo after cropping:
32 - 0.07 = 31.99 square ft
Hence,
The required area of the photograph is 31.99 ft².
