Agroup of 6 children and 7 adults are going to a movie. child tickets cost $4, and adult tickets cost $8. how much will the movie tickets cost in all?

$84

Step-by-step explanation:

Since child tickets cost $4, and there are 6 children, multiply 7 and 4.

7 x 4 = 28

Then, since adult tickets are $8 each and there are 7 adults, multiply 7 and 8.

7 x 8 = 56

Add the two totals together: 56 and 28.

56 + 28 = 84

So, the movie tickets will cost $84 in all.

last option

step-by-step explanation:

given that δdef is right and isoceles,

assuming that side df is the hypotenuse means that de an ef are the other 2 sides that intersect at 90° and are of equal length.

because they are of equal length, we can say that they are congruent

because they intersect at 90°, their slopes must be opposite reciprocals.

only the last option satisfies these conditions.

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
