Solve for x in the diagram below.
Answer:
77
Step-by-step explanation:
why because 100+3=103
and this is half a circle so the answer is 180-103 that is 77
Answer:
x = 20°Step-by-step explanation:
From the question it can be seen that all the angles lie on a straight line and
Angles on a straight line add up to 180°
To solve for x add up all the angles and equate them to 180°
That's
x + 3x + 100 = 180
4x + 100 = 180
Subtract 100 from both sides
4x + 100 - 100 = 180 - 100
4x = 80
Divide both sides by 4
We have
[tex] \frac{4x}{4} = \frac{80}{4} [/tex]We have the final answer as
x = 20°Hope this helps you
What is the value of |-12| ?
Answer:
12
Step-by-step explanation:
the absolute value of any negative number is the number in positive form.
Answer:
Hello!
The value would 12 cause it is the absolute value
For example:
If the is negative 12 the absolute value would be the opposite, so it would be positive 12.
But if it was
|12| then it would stay the same

Each scoop of ice cream costs $3.50, which expression below represents the cost of x scoops of ice cream?
Answer:3.5•x or 3.5x
Step-by-step explanation:
Selena and Drake are evaluating the expression (StartFraction r s Superscript negative 2 Baseline Over r squared s Superscript negative 3 Baseline EndFraction) Superscript negative 1, when r = negative 1 and s = negative 2.
Selena’s Work
Drake’s Work
(StartFraction r s Superscript negative 2 Baseline Over r squared s Superscript negative 3 Baseline EndFraction) Superscript negative 1 Baseline = (r Superscript negative 1 Baseline s) Superscript negative 1 Baseline = StartFraction r Over s EndFraction = StartFraction negative 1 Over negative 2 EndFraction = one-half
(StartFraction (negative 1) (negative 2) Superscript negative 2 Baseline Over (negative 1) squared (negative 2) Superscript negative 3 EndFraction) Superscript negative 1 = (StartFraction (negative 1) (negative 2) cubed Over (negative 1) squared (negative 2) squared EndFraction) Superscript negative 1 = (StartFraction negative 8 Over 4 Endfraction) Superscript negative 1 Baseline = StartFraction 4 Over negative 8 EndFraction = negative one-half
Who is correct and why?
Selena is incorrect because she should have substituted the values for the variables first, and then simplifed.
Selena is correct because she simplified correctly and then evaluated correctly after substituting the values for the variables.
Drake is incorrect because he should have simplified first, before substituting the values for the variables.
Drake is correct because he substituted the values for the variables first, and simplified correctly
Answer:
Selena is correct because she simplified correctly and then evaluated correctly after substituting the values for the variables.
Step-by-step explanation:
Andrea, Beth, & Cathy's ages are consecutive whole numbers. Andrea is the youngest, and Cathy is the oldest. The sum of their ages is 54. How old is Cathy?
Answer:
Age of Cathy = 19
Step-by-step explanation:
Find:
Sum of their ages = 54
Assume;
Age of Andrea = x
Age of Beth = x + 1
Age of Cathy = x + 2
Sum of their ages = x + x + 1 + x + 2
54 = 3 x + 3
3 x = 51
x = 17
Age of Cathy = x + 2
Age of Cathy = 17 + 2
Age of Cathy = 19
What is the Solution
Answer:
16x=1 x=1/16 or 0.0625
2/5x=1 x=5/2 or 2.5
Step-by-step explanation:
for 16x=1 divide both sides by 16, 1 divided by 16 is 1/16 or 0.0625
for 2/5x=1 multiply by the reciprocal of 2/5 which is 5/2. 5/2 times 1 is just 5/2 or 2.5.

Julie goes to the park across the street from her house several times a day and jogs a total of six miles every day. She jogs three-fourths of a mile at a time. What is the divisor?
Answer:
The Divisor is 6 miles
Step-by-step explanation:
A Divisor is also defined as a number by which a another number called dividend is divided by with or without having a remainder.
Divisor ÷ Dividend = Quotient
We are told that Julie goes to the park and jogs a total of six miles every day. She jogs three-fourths of a mile at a time.
In 1 day = 6 miles
Spread throughout the day, or per time , Jules jogs 3/4 of a mile
To find out how many times she jogs in a day, 6 miles will be divided by 3/4
Divisor ÷ Dividend = Quotient
= 6 ÷ 3/4
= 8 times in a day.
Looking at the above, calculation, 6 miles is the Divisor.
Given that sin(90 -5ϴ) = Cos(180 - ϴ), Find the value of ϴ
Answer:
30°
Step-by-step explanation:
[tex] \because \: \sin(90 \degree - \theta) = \cos \theta \\ \therefore \: \sin(90 \degree - 5 \theta) = \cos 5\theta....(1) \\ \\ \sin(90 \degree - 5 \theta) = \cos(180 \degree - \theta)...(2) \\ from \: (1) \: and \: (2) \\ \cos 5\theta = \cos(180 \degree - \theta) \\ 5 \theta = 180 \degree - \theta \\ 5 \theta + \theta= 180 \degree \\ 6\theta= 180 \degree \\ \theta = \frac{180 \degree}{6} \\ \\ \huge \red{ \boxed{\theta = 30 \degree}}[/tex]

A building is of unknown height. At a distance of 400 feet away from the building, an observer notices that the angle of elevation to the top of the building is 35º and that the angle of elevation to a poster on the side of the building is 15º. How far is the poster from the roof of the building? Round your answer to the nearest tenth.
Given :
A building is of unknown height. At a distance of 400 feet away from the building .
An observer notices that the angle of elevation to the top of the building is 35º and that the angle of elevation to a poster on the side of the building is 15º .
To Find :
How far is the poster from the roof of the building .
Solution :
Height is given by :
[tex]h=d\times tan\theta[/tex]
( Here , [tex]\theta[/tex] is angle of elevation )
So , height of tower :
[tex]H=400\times tan 35^o\\\\H=280.08 \ feet[/tex]
For height of poster :
[tex]h=400\times tan 15^o\\\\h= 107.18\ feet[/tex]
Therefore , distance of poster from the roof of the building is :
[tex]( 280.08-107.18) = $$172.9\ feet[/tex]
Hence , this is the required solution .

The scale factor of a room for a scale drawing is 2.3. The actual length of a wall in the room is 46 feet and the actual width of the room is 69 feet. What is the area of the scale drawing?
50 square feet
500 square feet
600 square feet
1380 square feet
PLEASE HELP ME!!!!!!!
Answer:
There's two ways to solve this.
Step-by-step explanation:
First way:
Let's divide the width and length by 2.3.
46÷2.3=20
69÷2.3=30
20×30
600 ft²
Second Way:
Let's find the area of the actual room.
46×69
3,174 ft²
Let's find the scale drawing squared.
2.3²=5.29
3,174÷5.29

84.78 gallons of milk is sold for $11.00. If you want to buy 9.58 gallons of milk, how
much will you have to pay?
Answer:
You will have to pay $22.05.
Step-by-step explanation:
We can solve this problem by making a proportion:
4.78 gallons/11 dollars = 9.58 gallons/x dollars
By cross-multiplying, we can solve for x:
4.78x = 105.38
x = 22.05
