Answer:

d= 90 degrees

e= 66 degrees

f= 114

Step-by-step explanation:

D is 90 because the measure of the angle on the line is 180 and it shows that the other angle is 90 and 180- 90= 90. E is 66 because opposite angles are congruent. F is 114 because they lie on a straight line which has the measure of 180 and 180- 66= 114

Answer:

d = 90°

e = 66°

f = 114°

Step-by-step explanation:

d = 90°

e = 66°

Reason : Vertically opposite angles

Angles f and 66° are in the linear pair.

f + 66° = 180°

f = ( 180 - 66 )°

f = 114°

Answer:

x = 6

y = 2

Step-by-step explanation:

From the second equation (x - 3y = 0) we know that x = 3y, now we just substitute 3y instead of "x" in the first equation and get...

x + 2y = 10

3y + 2y = 10

5y = 10

y = 2

Now we can find "x" since we know what "y" is equal to.

x + 2y = 10

x = 10 - 2y

x = 10 - (2)(2)

x = 10 - 4

x = 6

Answer:

307

Step-by-step explanation:

You get the area from every side like so-

12 * 11= 132

12 * 5= 60

12 * 5=60

5 * 11 = 60

You add them all up to get 307.

I don't know if that's a 5 or a 3 on the side there but I can edit this if it's a different number.

Answer:

6/5 hours

Step-by-step explanation:

GIVEN :-

Lets say ,

TO FIND :-

PROCEDURE :-

In 2 hours , Pump A fills the whole tank.

⇒ In 1 hour , Pump A will fill 1/2 part of tank. (By using Unitary method)

In 3 hours , Pump B fills the whole tank.

⇒ In 1 hour , Pump B will fill 1/3 part of tank. (By using Unitary method)

In 1 hour , when both pumps will be used together , they will fill =

(Part of tank filled by A in 1hr) + (Part of tank filled by B in 1hr)

⇒  [tex]\frac{1}{2} + \frac{1}{3}[/tex]

[tex]=> \frac{5}{6}[/tex] part of tank

5/6 part of tank will be filled by both the pumps in = 1 hour.

Using unitary method, multiplying both the sides with 6/5 -

⇒ 5/6 × 6/5 part of tank will be filled by both the pumps in = 1 × 6/5 hours

⇒ Total tank (or 1 whole tank) will be filled by both the pumps in = 6/5 hours

∴ Both the pumps will take 6/5 hour to fill the tank , when used together.

The value of the probability represented by P(Take the bus | Sophomore) is 0.83

Conditional probabilities are probabilities that only occurred because an event has already occurred i.e. they are dependent on the initial event

From the table of values in the question, we have the following parameters:

The required probability represented by P(Take the bus | Sophomore ) = [?] is then calculated as:

P(Take the bus | Sophomore) = Number of students that (Take the bus and Sophomore) divided by Number of students that are (Sophomore)

Substitute the known values in the above equation

P(Take the bus | Sophomore) = 25/(2 + 25 + 3)

Evaluate the sum in the denominator

P(Take the bus | Sophomore) = 25/30

Evaluate the above quotient

P(Take the bus | Sophomore) = 0.83

Hence, the value of the probability represented by P(Take the bus | Sophomore) is 0.83

Answer:

100.48 square inches

Step-by-step explanation:

Surface area of a cylinder = 2πr(r+h)

r is the radius

h is the height

Given

radius = 9in

height = 7in

π = 3.14

Substitute into the formula

Surface area of the cylinder = 2(3.14)(9+7)

Surface area of a cylinder = 2*3.14*16

Surface area of a cylinder = 100.48 square inches

Hence the  amount of wrapping paper you need to wrap a gift in the

cylindrical box is 100.48 square inches

Renee can play 11 different games.

The most fundamental operations in arithmetic are addition, subtraction, multiplication, and division. However, arithmetic also includes more complex operations like manipulating percentages, square roots, exponentiation, logarithmic functions, and even trigonometric functions, which are analogous to logarithms. Other examples of more complex operations include exponentiation. Arithmetic expressions must be evaluated in accordance with the intended order of operations.

Given total amount Renee have = $60

Cost for entry in park = $25

The amount left with Renee = 60 - 25

The amount left with Renee =  $35

now cost for each game is $3

total no. of games can be played in $35 = [tex]\frac{ The amount left with Renee}{ cost for each game}[/tex]

 35/3  = 11.667

Hence we only count integer digits which is 11; so  Renee can play 11 different games.

Answer:

n = 5 units

Step-by-step explanation:

We can solve this using 2 different equations which lead to the same answer:

Equation #1: Sin(30) = n/10

=>Sin(30) * 10 = n

=> 5 = n

Equation #2: Cos(60) = n/10

=> Cos(60) * 10 = n

=> 5 = n

If a number is a whole number, it is in it's simplest radical form, therefore;    n = 5 units is the correct answer

Answer:

33.3 weeks

Step-by-step explanation:

Let us represent number of weeks = w

Investment a starts with $1000 and increases its value by $80 each week.

$1000 + $80 × w

1000 + 80w

Investment b starts with $2000 and loses $50 of its value each week.

$2000 - $50 × w

2000 - 50w

After how many weeks will the two investments have the same value?

1000 + 80w = 2000 - 50w

Collect like terms

80w + 50w = 2000 - 1000

130w = 1000

w = 1000/30

w = 33.333333333 weeks

Approximately

After 33. 3 weeks, the Investment will have the same value
