Answer:

distance: 7.81 miles

Explanation:

<u>simply use distance formula:</u>  \sf \sqrt{(y_2 -y_1)^2 + (x_2-x_1)^2}

  • coordinates: (4, 3), (10, 8)

<u>using the equation:</u>

\hookrightarrow  \sf \sqrt{(8-3)^2+(10-4)^2}

\hookrightarrow \sf \sqrt{(5)^2+(6)^2}

\hookrightarrow \sf \sqrt{25+36}

\hookrightarrow \sf \sqrt{61}

\hookrightarrow \sf 7.81  \ miles

A cube has a side length of x inches. What expression represents the total volume, in cubic inches, of the cube?
Pie

Answer:

Volume = x^3 cubic inches

Step-by-step explanation:

A cube is the 3D version of a square. Since one side length is x inches, all the other side lengths are same, x inches each.

We know,

Volume = area of base * height

THe base is a square and the area is side * side. We know each side is x, so we have:

Area of Square = Area of Base = x * x = x^2

Now, we know height is also same side length, x, thus the volume becomes:

Volume = area of base * height

Volume = x^2*x

We add the exponents when we have same base multiplied, so the expression for volume becomes:

Volume = x^2*x=x^3

A and B are complementary angles. If A = (x + 9) and m B = (7x – 15)° then find the measure of B.​
Marina CMI [18]

Answer:

coplementary \: angles \:  = 90° \\ (x + 9)° + (7x - 15)° = 90° \\ (8x  - 6)° = 90° \\ 8x = 90  + 6 \\ 8x = 96° \\ x = 12\\ angle \: B.  = ((7 \times 12)- 15) \\  = 69°

A lawnmower that regularly sells for $150 is on sale for $120. By what percentage was the price decreased?
yanalaym [24]

Answer:

20%

Step-by-step explanation:

Find the difference of both prices.

150 - 120 = 30

Calculate the ratio of the decrease in price to the original price.

30/150 = 0.2

Multiply the decimal by 100 to get your percentage.

0.2(100) = 20
