The ratio of boys to girls is 2 to 3. If there are 90 students in the band, how many of them are boys?

Answers

Answer 1

Answer:

36

Step-by-step explanation:

We can make an algebric equation.

2x+3x=90

5x=90

x=18

Since we wanna find the boys, we multiply the boys ratio with our x value.

2x=2•18=36 boys

Explain how to find the volume of the four ice cubes in the glass below if each ice cube is 2 inches wide. Pls help

Answers

The total volume of the ice cubes is 32 in^3

We know that, for a cube of side length L, the volume is:

V = L^3

So if we know that each of the ice cubes is 2 inches wide, we can see that the side length of each ice cube is 2 inches.

Then we have L = 2in

Then the volume of each ice cube is:

V = (2in)^3 = 8 in^3

And we have four of these, then the total volume is 4 times the volume of a single ice cube.

Total volume = 4*( 8 in^3) = 32 in^3

Suppose that a random parabola has a maximum vertex at (-7, 1). What
would be the value of the Axis of Symmetry for this parabola?
EXPLAIN

Answers

Answer:

x = -7   or   y = 1

Step-by-step explanation:

Since we are not given the actual formula for the parabola, we do not know in which direction the parabola is facing. The axis of symmetry is the value of the line that splits the parabola perfectly down the middle, to calculate this we need to know in which direction the parabola is facing. Since we do not have this information and only have the maximum vertex we can provide the two possible values for the Axis of Symmetry, which would be the following...

x = -7   or   y = 1

Create an equation which contains the solution (-1,3)

Answers

An equation 6x-(-2)y=0 where x = -1 and y = 3

Answer:

3x + y =0

Step-by-step explanation:

We need to create equation whose solution is (-1,3) . So let another point through which it passes be ( 0,0) .

Since at least two points are required for making a line .

Slope :-

=> m = -1-0/3-0

=> m = -1/3

Using point slope form :-

=> ( x - x1) = m( y - y1)

=> ( x - (-1)) = -1/3( y - 3)

=> (x + 1 )3= -y + 3

=> 3x +3 = -y + 3

=> 3x + y = 0

✔️ Checking :-

(-1,3)

=> 3(-1) + 3 = 0

=> -3+3=0

=> 0 = 0

Hence the equation can be 3x + y = 0 .

Write the equation of the line that goes through the point (-2, 8) with a slope of 1/2

Answers

Answer:

The answer is Y = 1/2x + 9

Step-by-step explanation:

The general equation with a slope and intercept is:

y=mx+b

We are given a slope of 1/2, which represents the "M" part of the equation.

So we have:

Y = 1/2x + b

We do not know what "b" is, so the equation is not complete.

We plug in "-2" for X and "8" for Y:

8 = 1/2 (-2) + b

b = 9

So, the full equation is: Y  = 1/2x + 9

What is the volume of the prism in cubic inches ?
what is the surface area in square inches ?

Answers

Answer:

Step-by-step explanation:

Volume

V = B * h

B = 1/2 a * b

Solution

Area of Triangles = B = 1/2 * 6 * 8

Area of Triangles = B = 24 square inches

Volume = B * H

Volume = 24 * 12

Volume = 288 cu in

Surface Area

Triangles

Area of one triangle = 24 square inches [ See Above ]

Area of two triangles = 48 square inches

Left Side

Area = L * W

L = 12

W = 8

Area = 12 * 8

Area = 96

Right side

Area = L * W

L = 12

W = 6

Area = 12 * 6

Area = 72

Area Back

L = 12

W = 10

Area = 12 * 10

Area = 120

Total = 120 + 72 + 96 + 48 = 336 square inches

What is the length of the line?
Choose 1 answer:

Answers

Answer:

√29

Step-by-step explanation:

We can use the pythagorean theorem to find the length of this line. You can draw a vertical line downwards from the higher point and a horizontal line towards the left from the lower point. This will create a right triangle. Wd can count the lengths of the legs, getting 2 and 5. We can substitute these values in the pythagorean theorem:

a^2 + b^2 = c^2

2^2 + 5^2 = c^2

4 + 25 = c^2

c^2 = 29

c = √29

Since c is the hypotenuse and is the same length of the line, the line is √29 units long
