Answer
44.
Explanation:
Step1: Compare decimal numbers
We need to compare the given decimal - number sets. For example, when comparing decimals, we start from the left - most digit after the decimal point.
Step2: Analyze each option
Let's assume the options are: a. (0.8>0.5>0.2>0.9) (incorrect as (0.9>0.8)) b. (0.9>0.8>0.5>0.2) (correct) c. (0.2>0.8>0.5>0.9) (incorrect as (0.9 > 0.8>0.5>0.2)) d. (0.9>0.2>0.8>0.5) (incorrect as (0.8>0.2))
Answer:
b
45.
Explanation:
Step1: Recall the sum of interior angles of a quadrilateral
The sum of the interior angles of a quadrilateral is (360^{\circ}).
Step2: Calculate the fourth angle
Let the fourth angle be (x). Given angles are (60^{\circ}), (110^{\circ}), and (90^{\circ}). Then (x=360-(60 + 110+90)). [x=360 - 260=100^{\circ}]
Answer:
b
46.
Explanation:
Step1: Translate the problem into an expression
If Jasley has (r) rings and King has 4 times as many, then the number of rings King has is (4r).
Answer:
a
47.
Explanation:
Step1: Identify the distances
The park is (\frac{9}{10}) miles from the school and the library is (\frac{3}{10}) miles from the school.
Step2: Calculate the difference
The difference in distance is (\frac{9}{10}-\frac{3}{10}=\frac{9 - 3}{10}=\frac{6}{10}=\frac{3}{5}) miles. But it seems there is a mistake in the options. If we assume the park is (9\frac{3}{10}) miles and the library is (3\frac{3}{10}) miles from the school, then (9\frac{3}{10}-3\frac{3}{10}=(9 - 3)+\left(\frac{3}{10}-\frac{3}{10}\right)=6) miles.
Answer:
a
48.
Explanation:
Step1: Add the costs
Toni paid (4.16) for a sandwich and (0.95) for a fruit. The total cost is (4.16+0.95 = 5.11).
Answer:
c
49.
Explanation:
Step1: Add the fractions
Arnold ate (\frac{3}{8}) of a pizza and Erick ate (\frac{1}{8}) of the same pizza. The total fraction of the pizza they ate is (\frac{3}{8}+\frac{1}{8}=\frac{3 + 1}{8}=\frac{4}{8}=\frac{1}{2}).
Answer:
d
50.
Explanation:
Step1: Recall the formula for the mean
The mean (\bar{x}=\frac{\sum_{i = 1}^{n}x_{i}}{n}), where (x_{i}) are the data - points and (n) is the number of data - points. Here, (n = 5), (x_1=65), (x_2 = 50), (x_3=56), (x_4=55), (x_5=64).
Step2: Calculate the sum
(\sum_{i=1}^{5}x_{i}=65 + 50+56+55+64=290).
Step3: Calculate the mean
(\bar{x}=\frac{290}{5}=58).
Answer:
c
51.
Explanation:
Step1: Recall the properties of substances
Gasoline contains toxic substances and is a poison. Sodium Chloride (table - salt) is not a poison, sugar is not a poison, and citric acid is not a poison in normal amounts.
Answer:
a
52.
Explanation:
Step1: Define the terms
The violence brought about by environmental pollution is ecological violence. Direct violence is more related to physical harm between individuals, socio - cultural violence is related to cultural and social norms, and structural violence is related to systemic inequalities.
Answer:
b
53.
Explanation:
Step1: Recall the functions of brain parts
The cerebrum is the part of the brain that reacts consciously. The cortex is a part of the cerebrum, the cerebellum is mainly involved in balance and coordination, and the thalamus is a relay center for sensory and motor signals.
Answer:
c
54.
Explanation:
Step1: Recall the properties of strawberries
We can tell that a strawberry is sweet by tasting it. Smelling it may give us an idea of its aroma but not necessarily its sweetness, looking at its color may tell us about its ripeness but not sweetness, and feeling its texture may tell us about its firmness but not sweetness.
Answer:
b
55.
Explanation:
Step1: Recall the function of the tongue
We can taste the bitterness of ampalaya and the sourness of sampaloc because our tongue has taste buds that can detect different tastes. Lips are not the main organs for tasting, the mouth is a general term and not the specific organ for taste detection, and while the tongue is a muscle, its taste - detecting ability is due to taste buds.
Answer:
a
56.
Explanation:
Step1: Recall the origin of life
The first living things on Earth were bacteria. People and animals evolved much later, and planets are non - living celestial bodies.
