What is 34 + 56 x 34 and have a great day ?
Kruka [31]

Answer:

1938

Step-by-step explanation:

For this, you will need to use order of operations. You would need to multiply 56 and 34 to get 1904 first, because multiplication comes before addition.

Remember to use PEMDAS.

A scale drawing of a rectangular painting is shown below. In the drawing, side E is 10 centimeters and side D is 24 centimeters.
Jobisdone [24]

Answer:

Side D is 0.78 feet (to 2 s.f.)

Step-by-step explanation:

In the Scale Drawing, side D=24 centimeters

1 foot = 30.48cm

x foot = 24 cm

Therefore:

24 X 1 = 30.48 X x

x= 24/30.48 =0.7874 feet

Side D is 0.78 feet (to 2 s.f.)
