<span>A rectangle has two pairs of sides of equal length. </span>
<span>So perimeter P = 2ft + 18in + 2ft + 18in </span>
<span>The units have to be all the same to add them so.... </span>
<span>P = 2ft + 1.5ft + 2ft + 1.5 ft </span>
<span>P = 7 ft. </span>
<span>So the board would have to be 7 feet to make a 2ft x 1.5ft picture frame.</span>
<span>supplement = 2(complement )+43
..
180-x=2(90-x)+43
180-x=180-2x+43
2x-x=43
x=43 deg</span>
Answer: 50 Batches
Step-by-step explanation:
16 ounces in a pound
12 pounds times 16 ounces is 192 ounces
192 ounces plus the extra 8 is 200 ounces of flour
200 divided by 4 ounces per batch
200/4= 50
Answer: There are 400 tadpoles in the year 1994.
This is because any point is of the form (x,y) where in this case
x = year number
y = tadpole population number
So (x,y) = (1994, 400) means x = 1994 and y = 400 pair up together.
In short, the year x = 1994 corresponds to the population of y = 400 tadpoles.
From the years 1990 to 1992, the population is increasing since the curve goes upward when moving from left to right. Then from 1992 to 1993, the population decreases hitting its lowest point in that specific region. From 1993 to 1997, the population increases before it decreases again from 1997 to 1999.
Answer:
ENGLISH SYSTEM:
What you want to do is simply convert the feet into inches for 1a. and for 1b. add the inches to the length and the width. For the rest of the English system, what you have to do is plug in the numbers.
METRIC SYSTEM:
So for this one it is the same thing but different measurements. Instead of converting feet to inches, you are converting meters to centimeters. Follow the same steps as you did with the English system.
Step-by-step explanation:
1a.
13*12=156
18*12=216
1b.
156+6=162
216+9=225
2.
162*225=36,450
3.
3.75*8=30
4.
36,450/30=1,215
1a.
4*100=400
5*100=500
2.
400*500=200,000
3.
9.5*20=190
4.
200,000/190≈1,053
