Answer:
Step-by-step explanation:
Let's say the Physics book costs $x
The Chemistry book will cost $x - $6
Two such Chemistry books will cost;
2($x - $6) = $(2x - 12)
Three such Physics books cost $3x
$(2x - 12) + $3x = $123
$5x - $12 = $123
$5x = $111
x = $22
So the Physics book costs; $22
and the Chemistry book costs $22 - 6 = $16
Answer:
A) 40 feet.
B) 7 inches.
Step-by-step explanation:
A) To acquire 8 inches, multiply the corresponding scale factor by 8:
1 inch equals 5 feet; 8 inches equals 40 feet
The genuine house stands 40 feet tall.
B) You can write the percentage if you want...
dwg / (35 feet) = 1 in / (5 ft)
When you multiply by 35 feet, you get...
7 in dwg = (1 in)(35 ft)/(5 ft)
In the scale drawing, the home measures <em>7 inches in length</em>.
Answer:
1/4, 25%, or 0.25
Step-by-step explanation:
Therefore, as each suit contains 13 cards, and the deck is split up into 4 suits, that leaves us with a 13/52 chance to pick a spade.
That fraction is equivalent to 1/4, so that leaves us with a probability of picking a spade at:
1/4, 25%, or 0.25
