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:

solve the equation:

y=-1/8

substitute -1/8 for y:

x=2(-1/8)+8

solve the equation:

x=31/4

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

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.

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:

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.
