Answers

Answer:

w = 35

Step-by-step explanation:

The angle adjacent to 125° is

180° - 125° = 55°

The 3 angles on the straight line sum to 180° , that is

90 + w + 55 = 180

w + 145 = 180 ( subtract 145 from both sides )

w = 35

Answers

Answer:

187

Step-by-step explanation:

Answer:

$126

Step-by-step explanation:

They need to know how much money they would make in 6 days so we need to find out how much each day they make. so it would be 28/4 = 7 so they sold 7 cookies each day so it would be 7 * 6 (The days and the cookies multiplied then we do this by 3 dollars to figure out how much money) = 42 cookies * 3 = 126.

Jillian pays 4$ every week so it would be 4x4 which is $16 in 4 weeks so the amount remaining would be $20

At the school election there were three candidates. Isabella got 40 votes, Amelia got 60 votes and Mason got ⅓ of the votes. How many people voted in the election?

Answers

Answer: 150 people voted in the election.

Step-by-step explanation:

Let x = Total number of votes.

Mason got [tex]\dfrac{x}{3}[/tex] votes.

Isabella got 40 votes, Amelia got 60 votes.

Then,

Combined votes = [tex]40+60+\dfrac{x}{3}=x[/tex]

[tex]100=x-\dfrac{x}{3}\\\\100=\dfrac23x\\\\ x=100\times\dfrac32\\\\ x=50\times3\\\\ x=150[/tex]

Hence, 150 people voted in the election.

A temperature in degrees Fahrenheit is shown in expanded notation. ( 9 × 10 ) + ( 4 × 0.1 ) How is this temperature in degrees Fahrenheit written a numeral?

Answers

Answer:

90.4 degrees.

Step-by-step explanation:

(9 x 10) + (4 x 0.1)

= 90 + 0.4

= 90.4.

The Temperature in Fahrenheit  is 90.4 F.

What is Expanded form?

The division of numbers into groups according to place value, such as ones, tens, hundreds, thousands, ten thousand, and so forth, results in the expanded form of the number. The expanded version of the number is the one that is represented by the sum of each digit times its place value.

Given:

Expanded notation. ( 9 × 10 ) + ( 4 × 0.1 )

Now, simplifying the expression

= (9 x 10) + (4 x 0.1)

= 90 + 0.4

= 90.4.

Hence, the Temperature in Fahrenheit  is 90.4 F.
