Work out the lengths of sides a and b.<br> Give your answers to 1 decimal place.

torisob [31]

Step-by-step explanation:

${a}^{2} = {8}^{2} + {5}^{2} \\ {a }^{2} = 64 + 25 \\ {a}^{2} = 89 \\ a = \sqrt{89} = 9.4 \: cm$

${17}^{2} = {12}^{2} + {b}^{2} \\ {b}^{2} = {17}^{2} - {12}^{2} \\ {b}^{2} = 289 - 144 \\ {b}^{2} = 145 \\ b = 12 \: cm$

A construction worker is looking at blueprints drawn to a 1/20 scale and notices that a wall is 0.5 feet by 0.25 feet. He claims

Gnoma [55]

Answer:

incorrect

Step-by-step explanation:

we are finding area which is squared, or we can put it in an equation, (0.5*20)*(0.25*20) or 0.5*0.25*20^2 which equals 50 but (0.5*0.25)*20 only equals 2.5 therefor he is incorrect and the correct answer would be 20^2 or 400 times the area.

hope this helps :)

What is the slope of the line that goes through the points (7,10) and (3,-3)

PilotLPTM [1.2K]

Ypu would subtract Y from the other points Y
$- 3 - 10 = - 13$
Then you would subtract X from the ither points X.
$3 - 7 = - 4$
Then you would put the Y value over the X
$\frac{ - 13}{ - 4}$
Then simiplify
$\frac{13}{4}$
