Answer:
Capacity of Tank B = 750 gal
363 gal in Tank A and 397.5 gal in Tank B
Step-by-step explanation:
(a) Volume of Tank B
V_A = 550 gal
V_A/V_B = 11/15
550/V_B = 11/15
Multiply each side by 15 (15 × 550)/V_B = 11
Multiply each side by V_B 5 × 550 = 11V_B
Divide each side by 11 15 × 50 = V_B
V_B = 750 gal
The capacity of Tank B is 750 gal.
(b) Water in each tank
In Tank A: 550 × 0.66 = 363 gal
In Tank B: 750 × 0.53 = 397.5 gal
There are 363 gal in Tank A and 397.5 gal in Tank B.
Answer:
mean lean body mass of the lean monkeys = 8.4kg
mean lean body mass of the obese monkeys = 10.4kg
Step-by-step explanation:
a) Mean = Sum of Body mass/number of body mass
For lean monkeys, mean = (6+7.5+9.2+9.7+9.1+9.1)/6
Mean = 50.6/6
Mean = 8.4
b)
for obese monkeys, mean = (8+9.1+10.3+12+11.9+11.2)/6
Mean = 62.5/6
Mean = 10.4
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)

Step-by-step explanation:
Answer: A (5, -5.5)
Step-by-step explanation: To find the midpoint of a line segment, you must know the formations of points. Two coordinates are made up of (x1, y1)(x2, y2). Now, to find the answer, you have to add the two x's (which is 4 and 6 = 10) and divide by 2 which equals 5. Now to find the y point, add both y's together. -5 + -6 = -11, and dividing by 2 gives you -5.5
Thus, the midpoint is (5, -5.5)
