Answer:

Radical: 5√13

Decimal: 18.0

Step-by-step explanation:

Given the dimension of the board given as 10ft by 15ft

If the board is nailed diagonally, the length of the bracing board will be gotten using the pythagoras theorem;

d² = 10² + 15²

d² = 100 + 225

d² = 325

d = √325

Expressing in radical form;

d = √325

d = √25*13

d = 5√13

Hence the length of the board in radical form is 5√13 feet

Express in decimal form;

d = √325

d = 18.0

Hence the length of the board to the nearest tenth is 18.0 feet

Answer:

<h2>1.5</h2>

Step-by-step explanation:

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

Here's how we solve the equation

-1.2\left(3-x\right) = -1.8

-1.2\left(3-1.5\right) = -1.8

-3.6+1.2\cdot1.5 = -1.8

1.2\cdot1.5 = -1.8

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

(-7,-8),(-6,7) Distance formula
IRISSAK [1]

Step-by-step explanation:

let

(-7,-8) =(x1, y1)

and (-6,7)=(x2, y2)

by the formula

d=√(y2-y1) ²+(x2-x1) ²

=√(7+8)²+(-6+7)²

=√15²+1²

= √225+1

= √226

Please help me solve this problem
Stells [14]

Answer:

$180

Step-by-step explanation:

To solve, we can set up a proportion and solve.

You earn $45 for 7.5 hours of work, and you earn $ x for 30 hours of work

45/7.5=x/30

Cross multiply

45*30=7.5*x

1350=7.5x

To solve for x, we need to get x by itself. It is being multiplied by 7.5. To undo this, divide both sides by 7.5

1350/7.5=7.5x/7.5

180=x

So, for 30 hours of work, you would earn $180
