Ray’s Lawn and Garden bought 300 lawnmowers for $75.00 each to stock the store for spring. If the 300 lawnmowers are sold for $1
grigory [225]
First you would have to calculate the total price the lawn mowers are bought for. Which you would multiply
300 × 75 = $22,500.
After you do that you get the total in which all 300 lawnmowers would be sold for. In this, you would multiply
300 × 104.95 = $31,485
Once you get these answers you will subtract 
$31,485 - $22,500 = $8,985

Need help on this equation its on the paperclip
s344n2d4d5 [400]

Answer:

Blank 1: 1 Blank 2: 8 Blank 3: 72

Step-by-step explanation:

What it is basically saying is that 9*8 is equal to 10*8 - 1*8 [Blank 1]. 10 times any number is a friendly number, it all ends with a 0. The question is saying that it is easier to think of a friendly number and subtracting from that. 10 eights - 9 eights is equal to 1 eight. So we take away 1*8=8 from 10*8=80, or in other words, 80-8 [Blank 2]= 9*8=72 [Blank 3].

Are you starting to see what I mean?

Find x:<br> 4 x 6^2 + 9 = x
Leni [432]
4 x 6^2 + 9 = x

First, evaluate the power
4(6^2)+9=x
4(36)+9=x
Then, multiply the numbers
4(36)+9=x
144+9=x
Finally, add the numbers
144+9=x
153=x

Final answer: x=153

A = 11m, b = 8m and C = 2m for the triangle shown below.
Aleksandr-060686 [28]

Answer:

x = \sqrt{53}

Step-by-step explanation:

Using Pythagoras' identity on the upper right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides.

Let the third side be d, then

d² + b² = a² , that is

d² + 8² = 11²

d² + 64 = 121 ( subtract 64 from both sides )

d² = 57

Using Pythagoras' identity on the lower right triangle, then

x² + c² = d²

x² + 2² = 57

x² + 4 = 57 ( subtract 4 from both sides )

x² = 53 ( take the square root of both sides )

x = \sqrt{53}

Can yall help me with this? Thanks!
Julli [10]

Answer:

3π

Step-by-step explanation:

The arc length is just a fraction of the circumference of the circle which we know is represented by the equation L=2πr.

The radius is given ad 6. So the circumference is:

2*π*6=12π

Now, since the angle of the arc is 90°, this is 1/4 of the circle.

This means that the arc length of this section will be 1/4th of the total circumference which is:

12π/4=3π
