You can remove your cofusion regarding wall in the blue print whether to be cosidered in inch or ft , be sure, it has to be in inches to be considered , with the scale of 1: 10 and specific mention of length of the wall 8 in , we have to cosider length of wall : 8 inch x 10 inch / 1 scale = 80 inches ( and not 80 ft ) , and in terms of ft it would be = 80 inches / 12 inches per ft = 6.6666 ft

Triangle PQR and triangle XYZ are similar. The length of PQ= 4 inches, PR = 9 inches and QR = 12 inches. The length of the short

defon

Simplified Recap:

PQR and XYR are similar.

PQ: 4 inches (shortest side)

PR: 9 inches

QR: 12 inches (longest side)

Solving:

Because they are similar triangles, we know that the sides of one triangle are proportional to the ones on the other. Therefore, the smallest side of PQR is proportional to the smallest side of XYZ. Now, we just need to figure out the constant of proportionality , and we can do that by dividing the smallest side of XYZ triangle by the smallest side of PQR.

$16 \div 4 = 4$

Now we know that the constant of proportionality is 4. All we have to do now is solve the problem. The question is asking what the longest side of XYZ is, and to find that we just need to multiply the longest side of PQR by our constant of proportionality.

$12 \times 4 = 48$

Therefore, our answer is 48.

Rachel enjoys exercising outdoors. Today she walked 5 2/3 miles in 2 2/3 hours. What is Rachel's unit walking rate in miles per

anyanavicka [17]

Answer:

a) 2 1/8 miles per hour

b) 8/17 hours per mile

Step-by-step explanation:

To find the rate in mile per hour, divide miles by hours:

(5 2/3 mi)/(2 2/3 h) = (17/3 mi)/(8/3 h) = 17/8 mi/h = 2 1/8 mi/h

To find the rate in hours per mile, invert that number:

1/(17/8 mi/h) = 1/((17 mi)/(8 h)) = (8 h)/(17 mi) = 8/17 h/mi
