Answer:
1. 180 - 75 - 60 = 45
180 - 45 = 135
2. 180 - 23 - 37 = 120
180 - 120 = 60
180 - 60 - 56 = 64
3. ion know lol
Answer:
1) 135°
2) a = 64°; b= 60°; c=120°;
3)135°
Step-by-step explanation:
1. Interior angles of triangles must add up 180°.
75° + 60° = 135°
Missing angle is 45° (180° - 135° = 45°)
x is supplementary to 45, so 135° (you would do 180° - 45°)
2.
To find a:
56° + 23° = 79°
79° + 37° = 116°
180° - 116° = 64°
To find b:
56° + 64° (a) = 120°
180° - 120° = 60°
To find c:
180° - 60° (b) = 120°
OR
23° + 37° = 60°
180° - 60° = 120°
3. Pentagon's interior angles must add up to 540°
540° - (70° + 110° + 90°)
540° - 270°
270° = 2x ––divide by 2
135° = x

Recall that there are 2π radians in one full rotation and 360 degrees in one full rotation.
Suppose an angle has a measure of 2.1 radians.
This angle (with a measure of 2.1 radians) is what percent of a full rotation?
 %
Use your work in part (i) to determine the measure of the angle in degrees.
 degrees
Answers
Answer: (i) This angle is 33.41% of the full rotation.
(ii) 120.38°
Step-by-step explanation:
GIven: Measure of full rotation = 2π radians
Measure of an angle = 2.1 radians.
The percent of this angles of a full rotation = [tex]\dfrac{2.1}{2\pi}\times100\%[/tex]
[tex]=\dfrac{2.1\times7}{2\times22}\times100\% \ \ \ \ [\pi =\dfrac{22}{7}]\\\\=33.41\%[/tex]
i.e. This angle is 33.41% of the full rotation.
In degrees,
[tex]\text{ 2.1 radians}=2.1\times\dfrac{180}{\pi}\\\\=2.1\times\dfrac{180}{3.14}\approx120.38^{\circ}[/tex]
[tex]2.1\text{ radians}[/tex] is [tex]33.4\%[/tex] of a full rotation and is equivalent to [tex]120.2^\circ[/tex]
The relationship between degree and radian measures is
[tex]1\text{ radian}=\dfrac{180}{\pi}^\circ[/tex]
Part 1We want to express [tex]2.1\text{ radians}[/tex] as a percentage of a full rotation.
[tex]\dfrac{2.1}{2\pi}\times100\%=\dfrac{210}{2\pi}\%\\\\\approx33.4\%[/tex]
Part 2How do we determine the measure of an angle (in degrees) given the percentage? Simply multiply the percentage by the complete/full rotation (that is [tex]360^\circ[/tex])
[tex]33.4\%\times360^\circ\\\\=\dfrac{33.4}{100}\times360^\circ\\\\\approx120.2^\circ[/tex]

79% of a university's freshman class are majoring in Engineering. If 2765 students in the freshman class are Engineering majors, how many students are in the freshman class?
Answers
Answer:
3500
Step-by-step explanation:
2765 / .79 = 3500
There are total 3500 students in the freshman class.
How can we represent "a% of b"?We can represent "a% of b" as -
a% of b = a/100 x b
a% of b = ab/100
So, a% of b = ab/100
Given is that 79% of a university's freshman class are majoring in Engineering. 2765 students in the freshman class are Engineering majors.
Assume that there are {x} number of students in the freshman class. So, we can write -
79% of {x} = 2765
79x/100 = 2765
{x} = 276500/79
{x} = 3500
Therefore, there are total 3500 students in the freshman class.

Sara ordered 2 slices of pizza and a 12-ounce cola and paid
$3.00. Sydney ordered 3 slices of pizza and 2 12-ounce
colas for $4.75. How much does a slice of pizza cost?
Answers
Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.
Step-by-step explanation:
Let slice of pizza cost x and a 12-ounce cola cost y.
Then Sara's order cost: 2x+y=3
and Sydney's order cost: 3x+2y=4.75
From the first equation we have: y=3-2x and put this to the second equation:
3x+2(3-2x)=4.75
3x+6-4x=4.75
x=1.25
y=3-1.25*2=0.50
Answer: a slice of pizza cost $1.25 and a 12-ounce cola cost $0.50.

Answer:

Step-by-step explanation:
Solve for b:
1 = 3 b - 1
1 = 3 b - 1 is equivalent to 3 b - 1 = 1:
3 b - 1 = 1
Add 1 to both sides:
3 b + (1 - 1) = 1 + 1
1 - 1 = 0:
3 b = 1 + 1
1 + 1 = 2:
3 b = 2
Divide both sides of 3 b = 2 by 3:
(3 b)/3 = 2/3
3/3 = 1:

A large rectangular box has a volume of 15.75 cubic feet the box is 2.5 feet long and 1.5 feet wide what is the height of the box
Answers
9514 1404 393
Answer:
4.2 ft
Step-by-step explanation:
The volume is the product of the dimensions:
V = LWH
Filling in the given values, we can solve for H.
15.75 ft³ = (2.5 ft)(1.5 ft)H
H = 15.75/(2.5×1.5) ft = 4.2 ft
The height of the box is 4.2 feet.

If the plumbing is faulty in 5% of the rooms at the Ramada Inn, in 4% of the rooms at the Sheraton, and in 8% of the rooms at the Lakeview Motor Lodge, what is the probability that
Answers
Answer:
Step-by-step explanation:
From the given information;
Let R represent Ramadan Inn
S to represent Sheraton; &
L to represent Lakeview Motor
F to represent faulty plumbing
So;
P(R) = 0.2
P(S) = 0.5
P(L) = 0.3
P(F|R) = 0.05
P(F|S) = 0.04
P(F|L) = 0.08
Then; to find the probability there will be a client assigned to the faulty room.
i.e.
P(F) =( P(R) × P(F|R) ) + ( P(S) × P(F|S) ) + ( P(L) × P(F|L) )
P(F) = (0.2 × 0.05) + (0.5 × 0.04) + (0.3 × 0.08)
P(F) = 0.01 + 0.02 + 0.024
P(F) = 0.054
suppose an individual with a room possessing faulty plumbing was given an accomodation at Lakeview Motor
Then:
P(L|F) = P(L) × P(L|F) / P(F)
P(L|F) = 0.3 × 0.08 / 0.054
P(L|F) = 0.4444
