Help meeeeeeeeeeeeeeeeeeeee

Answer 1

25. time = distance/speed

$\displaystyle t=\frac{66.5\,ft}{105\,\frac{mi}{h}}\times\dfrac{3600\,s}{h}\times\frac{1\,mi}{5280\,ft}\\\\=\frac{66.5\times 3600}{105\times 5280}\,s=\frac{19}{44}\,s\approx 0.432\,s$

It took about 432 milliseconds for the ball to travel to the batter.

26. 15 cans at Save Rite will cost 5 times the amount for 3 cans, so will be

... 5×$5.25 = $26.25

15 cans at Spend Less will cost 3 times the amount for 5 cans, so will be

... 3×$7.50 = $22.50

Maria paid $22.50 at Spend Less.

27. Simple interest is computed using

I = Prt . . . . where P is the principal, r is the annual rate, and t is the number of years.

Filling in the numbers gives the interest charge.

I = $8000×0.065×4 = $2080

Malik pays back the principal plus interest, so pays $8000 +2080 = $10,080.
