the table below shows the number of grade 7 and grade 8 students who chose cheese pizza or pepperoni pizza as their favorite piz

vova2212 [387]

Answer:

47% of the students who chose pepperoni pizza as their favorite

Answer (D)

Step-by-step explanation:

∵ The total number of the students in grade 7 is

171 + 254 = 425 students

∵ The total number of the students in grade 8 is

285 + 143 = 428 students

∴ The total number of students in both grades is

425 + 428 = 853 students

∵ The number of students in grade 7 who like pepperoni pizza

as their favorite is 254

∵ The number of students in grade 8 who like pepperoni pizza

as their favorite is 143

∴ The number of students who like pepperoni pizza as their

favorite in both grades = 254 + 143 = 397 students

∴ % of student who chose pepperoni pizza as their favorite is

(397/853) × 100 = 46.5% ≅ 47%

∴ The answer is (D)

A steamer going downstream traveled the distance between two ports in 3 hours. The return trip took 3 hours and 40 minutes. Find

marissa [1.9K]

Answer:

1.8 mph

Step-by-step explanation:

first, let's convert 3 hour 40 minutes into hours (to keep same units).

40 minutes is 40/60 = 2/3 hour

So 3 hr 40 minutes = $3\frac{2}{3}=\frac{11}{3}$ hours

Now, we know D = RT

where D is distance, R is rate, and T is time

Let rate of steamer be x (which is 18)

and rate of current be c

Rate Downstream = x + c (goes with current)

Rate Upstream = x - c (goes against current)

Both Distance (upstream & downstream) are same. Thus, we can write:

$D_{down}=D_{up}\\(x+c)t=(x-c)t\\(18+c)(3)=(18-c)(\frac{11}{3})$

Now, we solve this algebraically for "c", speed of current:

$(18+c)(3)=(18-c)(\frac{11}{3})\\54+3c=\frac{198}{3}-\frac{11}{3}c\\3c+\frac{11}{3}c=\frac{198}{3}-54\\\frac{20}{3}c=12\\c=\frac{12}{\frac{20}{3}}\\c=12*\frac{3}{20}=1.8$

Thus, speed of current = 1.8 mph
