Answer:
180 square feet
Step-by-step explanation:
A rug that is geometrically similar to her room floor is one that has the same size as her room floor.
The floor has dimensions 12 feet by 15 feet.
The area of the floor and hence, the rug is:
A = 12 * 15 = 180 square feet
She should buy a rug that is 180 square feet
Hello! So, the train travels 80 miles in an hour. 90 minutes is equivalent ot 1 ½ hours. In case you don't know, ½ of 80 is 40. To find the distance gone in 90 minutes, we can just add 80 and 40. 80 + 40 is 120. Another way to solve it is to multiply 80 by 1.5 and you would still get the same answer. There. The train will have gone 120 miles in 90 minutes.
Answer:
less
Step-by-step explanation:
Answer: C
Step-by-step explanation:
Convert all equations into slope-intercept form, the equation must have a slope of 1/4 and a y-intercept of -2
A) x + 4y = -8
4 ÷ (4y = - x - 8) ÷ 4
y = -1/4x - 2 --> Not the correct equation because slope is negative
B) 4x - y = 2
-1 ÷ (- y = 2 - 4x) ÷ -1
y = 4x - 2 --> Not the correct equation as the slope is not a fraction
C) x - 4y = 8
-4y = 8 - x
-4 ÷ (x - 4y = 8) ÷ -4
y = 1/4x - 2 --> Therefore, C is the correct equation
