10.angles b and c are called ____________ angles. A) complementary B) linear C) supplementary D) vertical
Answers
Answer:
Step-by-step explanation:
7). Since, game board is circular in shape,
Area of the game board = πr²
Here r = radius of the circle
And Radius of a circle = [tex]\frac{1}{2}(\text{Diameter})[/tex]
Therefore, radius of the circle = [tex]\frac{2.5}{2}[/tex] = 1.25 ft
Area of the game board = π(1.25)²
= 3.14(1.25)²
= 4.91
≈ 5 ft²
Option C is the answer.
8). Scale on he map is,
1 cm = 9.8 miles
Distance between Old faithful and West Thumb = 2.5 cm
By using scale,
2.5 cm = 2.5 × 9.8 miles
= 24.5 miles
Therefore, actual distance between Old faithful and West Thumb = 24.5 miles.
9). From the given picture angles b and c are Vertically opposite angles.
Therefore, these angles are vertical angles.
Option D is the answer.

Two observers simultaneously see an airplane overhead and between them. They measure
their angle of elevation to the airplane and obtain 48° and 73º. The airplane is 1.7 miles
directly above the point shown in the figure below. How far are the two observers from each
other? Round your answer to the nearest hundreth of a mile.
Answers
Answer:
2.05 mi
Step-by-step explanation:
I don't see a figure, so I am guessing that the plane is 1.7 miles above the ground.
Let x = distance of observer 1 from that point
y = distance of observer 2 from that point
Tan 48 = 1.7/x and tan 73 = 1.7/y
x tan 48 = 1.7 y tan 73 = 1.7
x = 1.7/tan 48 y = 1.7/tan 73
x + y = distance between the observers
x + y = 1.7/tan 48 + 1.7/tan 73
= 2.05 mi

Calculate the total surface area of the rectangular prism
Answers
Answer: C. 170.3 cm squared
Answer:
170.3cm^2
Step-by-step explanation:
The total surface area is the sum of surfaces of all sides.
We have 2 sides of 7.9cmx4.5cm, 2 sides of 7.9cmx4cm, and 2 sides of 4.5cm*4cm.
7.9cm*4.5cm = 35.55cm^2
7.9cm*4cm = 31.6cm^2
4.5cm*4cm = 18cm^2
2 * (35.55cm^2 + 31.6cm^2 + 18cm^2) = 2 * 85.15cm^2 = 170.3cm^2

A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?
Answers
Answer:
8 38/45 inches
Step-by-step explanation:
A regular size chocolate bar is 5 and 4/9 inches long. If the king size bar is 3 and 2/5 inches longer, what is the length of the king size bar?
Let us represent:
Length of regular size chocolate bar = x
Length of king size chocolate bar = y
A regular size chocolate bar is 5 and 4/9 inches long.
x = 5 4/9 inches
If the king size bar is 3 and 2/5 inches longer,
Hence:
y = x + 3 2/5 inches
The length of the king size bar is calculated as:
5 4/9 inches + 3 2/5 inches
(5 + 3) + ( 4/9 + 2/5)
Lowest common denominator = 45
8 + (20 + 18/45)
8 38/45 inches

Answers
Answer:
14/5
Step-by-step explanation:
Given data
We have the function
f(x)= (3x+2)/5
We want to find f(4)
Hence, let us place x= 4 in the function
f(4)= (3(4)+2)/5
f(4)= (12+2)/5
f(4)= (14)/5
f(4)=14/5
Hence f(4)= 14/5

Na casa de Isabel, a leitura do hidrômetro, feita no dia 20 de março, indicava 2431 metros cúbicos. Uma nova leitura, feita um mês depois, indicou 2 590 metros cúbicos. Quantos metros cúbicos de água Isabel e seus familiares consumiram nesse período?
Answers
Answer:
159 metros cúbicos
Step-by-step explanation:
Os metros cúbicos de água que Isabel e sua família consumiram durante este período são calculados como:
Nova leitura - primeira leitura
Primeira leitura = 2.431 metros cúbicos
Nova leitura = 2590 metros cúbicos
Conseqüentemente:
2.590 metros cúbicos - 2.431 metros cúbicos
= 159 metros cúbicos
