Mathematics
1 answer:
posledela3 years ago
7 0

Answer:

<em>Student 3 had the greatest percentage error.</em>

Step-by-step explanation:

<u>Student 1</u>

Actual length = 50in

Measured length = 49in

Error = 50 - 49 = 1

Error% = 1/50 × 100

= 1 × 2

= 2%

<u>Student</u><u> </u><u>2</u>

Actual length = 100cm

Measured length = 110cm

Error = 100 - 110 = 10

Error% = 10/100 × 100

= 10 × 1

= 10%

<u>Student</u><u> </u><u>3</u>

Actual length = 2cm

Measured length = 2.5cm

Error = 2 - 2.5 = 0.5

Error% = 0.5/2 × 100

= 0.5 × 50

= 25%

<u>Student</u><u> </u><u>4</u>

Actual length = 10ft

Measured length = 9½ft

Error = 10 - 9½ = ½

Error% = ½/10 × 100

= ½ × 10

= 1 × 5

= 5%

Reasoning Solve the system of linear equations using substitution. Use pencil and paper. Which
Y_Kistochka [10]

Answer:

Since the first equation x is equal to 4y - 9, it is easier to substitute 4y - 9 in for x in the second equation.

x = -1    y = 2

Step-by-step explanation:

Since the first equation x is equal to 4y - 9, it is easier to substitute 4y - 9 in for x in the second equation.  That would give you

4y - 9 + 4y = 7

8y - 9 = 7

8y = 16

y = 2

x = 4y - 9 = 4(2) - 9 = 8 - 9 = -1

It is always a good idea  to check and see if your results satisfy the two equations

The frame around a picture with an area of 192 square inches, measures x inches across. The length of the picture with its frame
prisoha [69]
Okay so
area of picture= 192cm
area of frame= 40×24=960

960÷ 192= 5

Therefore the picture is 1/5 of the frame.
Length of picture = 1/5 × 40 = 8cm
Width of picture = 192/8 = 24

The dimensions of the picture are then 8cm × 24 cm.
