1) Which expression is equal to
1 answer:
Answer:
None of the expressions in the option is equal to 10 x(13).
Step-by-step explanation:
The answer can be verified by calculating the values of the expression in the question, those of each options, and then compare as follows:
Value of the expression = 10 x (13) = 10 x 13 = 130
Therefore, we have:
A. 10 + (1+3) = 10 + 4 = 14 130
B. (10 x 1)+3 = 10 + 3 = 13 130
C. 10 + (1x3) = 10 + 3 = 13 130
D. (10 * 1)3 = 10 * 3 = 30 130
Based on the calculations above, none of the expressions in the option is equal to 10 x(13).

Answer:
The length of the field on the drawing is 55 cm.
Step-by-step explanation:
Given:
Mark made a scale drawing of a soccer field.
Using a scale of .5 cm=1 m.
The actual length of the field is 110 m.
Now, to find the length of the field on drawing.
Let the length of the field on drawing be
As given 0.5 cm is equivalent to 1 m.
Thus, is equivalent to 110 m.
Now, to get the length of the field on drawing by using cross multiplication method:
<em>By cross multiplying we get:</em>
⇒
⇒
Therefore, the length of the field on the drawing is 55 cm.
