Answer: 705 cm

Step-by-step explanation:

Ron and Hermione are lifting feathers into the air with magic. Hermione can lift a feather 3,525

centimeters (cm) into the air. That is 5 times as high as Ron can lift a feather.

How high can Ron lift a feather with his magic?

Hermione = 3,525 cm

Hermione = 5 × Ron

Substitute Hermione = 3,525 cm into

Hermione = 5 × Ron

3,525 = 5 × Ron

Ron = 3,525 / 5

= 705

Ron = 705 cm

Answer:

450 words at a rate of 45 word per minute

Step-by-step explanation:

180 divided by 4 equals 45

times 10 equals 450

Answer:

450 words in 10 minutes

Step-by-step explanation:

To set this up you need to put it like this:

[tex]\frac{180}{4} =\frac{x}{10}[/tex]

From here, you need to cross multiply, which will get you to: 180(10) = 4x

Multiply 180 and 10: 1,800

The equation will now be: 1,800 = 4x

Now, divide both sides by 4:   450 = x

Answer:

first one is correct

Step-by-step explanation:

length of a rectangle = 2b - 8c

breadth of a rectangle = 10b + 6c

now , formula to calculate the perimeter of rectangle is

p = 2 (l + w)

no substitute the value of l(length) and w(width)

p = 2{(2b - 8c) + (10b + 6c)}

p = 2(2b - 8c + 10b + 6c)

p = 2(12b - 2c)

p = 24b - 4c

Answer:

should be 13

Step-by-step explanation:

Answer:

x = 60°, y = 100°, z = 120°, w = 80°

Step-by-step explanation:

x and 120° are adjacent angles on a straight line and sum to 180°

x + 120° = 180° ( subtract 120° from both sides )

x = 60°

Similarly

y + 80° = 180° ( subtract 80° from both sides )

y = 100°

and

z + 60° = 180° ( subtract 60° from both sides )

z = 120°

--------------------------------------------------------------------

The sum of the interior angles in a quadrilateral = 360°

sum the interior angles of the quadrilateral and equate to 360°

60° + 80° + 120° + 4th angle = 360°

260° + 4th angle = 360° ( subtract 260° from both sides )

4th angle = 100°

w and 100° are adjacent angles on a straight line and sum to 180° , so

w + 100° = 180° ( subtract 100° from both sides )

w = 80°

Answer:

  h = r +4d -m

Step-by-step explanation:

There are a couple of ways to go about this:

1) Solve it the way you would any 2-step linear equation.

Step 1:

Identify the terms that do not involve h on the side of the equation that has the h-term. Subtract those terms from both sides of the equation.

  m -r -4d = -h

Step 2:

If the coefficient of h is not 1, divide both sides of the equation by that coefficient.

  (m -r -4d)/(-1) = (-h)/(-1)

  -m +r +4d = h

I like to have the leading coefficient be positive, so I might write this as ...

  h = 4d +r -m

__

2) The only h term has a -1 coefficient, so it can be given a coefficient of +1 by adding h to both sides of the equation.

  h +m = r +4d

There is an unwanted m term with the h term, so subtract that from both sides of the equation.

  h = r +4d -m

Answer:

h = 4d -m + r

Step-by-step explanation:

m = r-h +4d

h = 4d -m + r

we know when the real root is  r = h-4d  

the m+h = r+4d is step 1

then simply h-m = 4d-m + r is step 2

then h = 4d -m + r

Answer: 18

Step-by-step explanation:

15% is [tex]\frac{15}{100}[/tex] which is equal to 0.15

Multiply 0.15 times 120 and you will get the answer below:

0.15 × 120 = 18

Answer:

33.2

Step-by-step explanation:

When you add the left side of the equation, you get 33.2 because 70-30 is 40, 40+2 is 42, 42-9 is 33, 33+0.3 is 33.03, 33.3-0.1 is 33.2.

When you add the right side of the equation, you get 33.2, because they are the same problem but on side has brackets.

Hope this helps you.

Answer:

72π (in terms of pi)

Step-by-step explanation:

V = π·r²·h

Plug in the values.

V = π·3²·8

Solve.

V = 72π

To leave an equation in terms of pi, just square, multiply, and leave pi at the end.

3² = 9·8 = 72

72π

If you need the answer fully simplified, it is 226.19 (rounded up).

Answer:

x = 4 , y = 2

Step-by-step explanation:

Using the sine / tangent ratios in the right triangle and the exact values

sin60° = [tex]\frac{\sqrt{3} }{2}[/tex] and tan60° = [tex]\sqrt{3}[/tex] , then

sin60° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{2\sqrt{3} }{x}[/tex] = [tex]\frac{\sqrt{3} }{2}[/tex] ( cross- multiply )

x [tex]\sqrt{3}[/tex] = 4[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

x = 4

and

tan60° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{2\sqrt{3} }{y}[/tex] = [tex]\sqrt{3}[/tex] ( multiply both sides by y )

y [tex]\sqrt{3}[/tex] = 2[tex]\sqrt{3}[/tex] ( divide both sides by [tex]\sqrt{3}[/tex] )

y = 2

Answer:

Step-by-step explanation:

for points don't take serious

The y-intercept of the line is (0, -5) and plot the coordinate points (0, -5) and (4, -8) on the graph.

The general equation of a straight line is y=mx+c, where m is the gradient, and y = c is the value where the line cuts the y-axis. This number c is called the intercept on the y-axis.

The given equation is y+2= -3/4 (x+4).

Graph the line using the slope and y-intercept, or two points.

Slope: -3/4

y-intercept: (0, -5)

Plot the coordinate points (0, -5) and (4, -8)

Hence, plot the coordinate points (0, -5) and (4, -8) on the graph.
