This is the concept of functions. We are required to calculate for the total cost of tickets if 27, 39 and 43 people attended a concert whose cost was represented by C=10n+26.
To solve for this we substitute the each values in the function as follows;
When n=27
C(27)=10*27+26=296
When n=39
C(39)=10*39+26=416
When n=43
C(43)=10*43+26
=456
Answer:
The strategy Pedro tend to do isn't worth, because using rigid transformation to place on figure onto the other won't prove that those figures are similar, but it would prove if they are congruent.
Remember that similarity is about proportionality between dimensions of those figures, so it's not about congruence. That means the figures won't match when we place one onto the other.
To prove similarity, Pedro should divide each pair of corresponding coordinate, if all divisions give the same result, that means those figures are similar.
<h3>Therefore, Pedro is not right.</h3>
Answer:
291.87 is a rational number.
Step-by-step explanation:
Rational numbers are those numbers that can be expressed in fractions that is can be written as 
where p and q are integers and 
.
Consider the given number 291.87
Rewrite the decimal number as a fraction with 1 in the denominator, we get,
Multiply to remove 2 decimal places. Here, you multiply top and bottom by 10² = 100
Thus, the above fraction can be written as,
Thus, 291.87 is a rational number.
Answer:
Step-by-step explanation:
Seeds for each row = Total number of seeds/Number of rows
=(1220+750+1450)/60
=3420/60
=57 seeds per row
