<span>1 inch = 1 foot is the answer. The</span> appropriate scale to use on an 8 1/2 by 11 sheet of paper for a sketch of the room and carpet is <span>1 inch = 1 foot. The other choices are incorrect because it is not possible for 1/2 inch= 1 foot and it is grammatically wrong when we say 1 inches= 1 foot.</span><span />
Answer:
148-13=135
4x+13= - 3.25
6x+2 = - 0.33
Step-by-step explanation:
1) SIMPLE SUBTRACTION
148
- 13
---------
135
---------
2)
4x+13=0
4x= - 13
x= -13/4
x= - 3.25
3)
6x+2 = 0
6x= -2
x= -2/6
x = -0.33
Answer: w ≤ 14 cm , L ≤ 42 cm
<u>Step-by-step explanation:</u>
width (w): w
Length(L): 3w
Perimeter (P) = 2w + 2L
P ≤ 112
2w + 2L ≤ 112
2(w) + 2(3w) ≤ 112
2w + 6w ≤ 112
8w ≤ 112
w ≤ 14
Answer:
77
Step-by-step explanation:
the dog ate half so there is only the other half left and there is 43 cards left
1 half + 1 half = 1 whole so 43 + 43 = 86
86 is the total after he bought 9 new cards
86 - 9 = 77
You must first normalize this in order to use a Z-score table. To convert what you have into a Z score you must use this formula: (x- mean) /standard deviation. In your case (334-310)/12=2. So now you want the probability that a score is greater than 334, which in turn means you want P(Z>2)=1-P(Z<2)=1-.9772=0.0228=2.28%.
