Clare estimates that her brother is 4 feet tall. When they get measured at the doctor’s office, her brother’s height is 4 feet, 2 inches.

1. Should Clare's or the doctor's measurement be considered the actual height? Explain your reasoning.

2. What was the error, expressed in inches?

3. What was the error, expressed as a percentage of the actual height?

Answers

Answer:

Percentage of error by Clare is estimated as 4.1667 %

Step-by-step explanation:

Height measured by Clare = 4 feet

Height measured by Doctor = 4 feet, 2 inches

Percentage error = ?

Percentage error = Difference/ Actual height *100

Percentage error = (2/ (4*12))*100

Percentage error = 4.1667 %

The accurate height is measured by Doctor, as he have more accurate measurement system.

3x {+ 2y = 23
x {– 2y = 8

Answers

Answer:

([tex]\frac{31}{4} , \frac{-1}{8}[/tex])

Step-by-step explanation:

use substitution:

3x+2y=23

x=2y+8

plug in 2y+8 for x

3(2y+8)+2y=23

distribute:

6y+24+2y=23

combine like terms:

8y+24=23

solve the equation:

y=-1/8

substitute -1/8 for y:

x=2(-1/8)+8

solve the equation:

x=31/4

Step-by-step explanation:

Supplementary means 2 angles adding up to 180 or the line of AEF in this case

so supplementary pairs like DEH and HEF would add up to 180, same with DEJ and JEF

Answer:

Angle DEH and angle HEJ and HEK and KEF add up to 180 degrees

Step-by-step explanation:

Two angles are called complementary if their measures add to 90 degrees, and called supplementary if their measures add to 180 degrees. ... For example, a 50-degree angle and a 40-degree angle are complementary; a 60-degree angle and a 120-degree angle are supplementary.

Store A sells boxes of rice for $2.50 each.

Store B sells rice by the pound for $2.50 per pound.

The cost of an amount of rice at either store can be modeled by the function c(n) = 2.5n, where n is the number of boxes for Store A and n is the number of pounds of rice for Store B.

The domain of c(n) = 2.5n is all the real numbers.

For each store, drag the restriction needed on values of n for c(n) to model each situation.

Answer:

Step-by-step explanation:

Store A: Sells rice in boxes= whole numbers greater than or equal to zero

What’s the area of this figure?

Answers

Answer:

374 mm

Step-by-step explanation:

There are two rectangles and one triangle. This means that we need to add the sum of two rectangles and one triangle together.

Rectangle 1:

19*9=171

Rectangle 2:

19*9=171

Triangle:

8*23*1/2=32

(We divide by 1/2 because it's a triangle)

Now we add them together.

171+171+32=374

In the end, the answer is 374. I didn't show all of my work because most of it was done mentally.

470 square mm. the area of the right triangle is 128 sq mm because 32x11=256 and 256/2=128
