Answer:
x=30° y=5
Step-by-step explanation:
All sides of the top triangle are equal. And all angles are equal Since it's an equilateral triangle.
so
8y=40
y=40/8
y=5
Since it's an equilateral triangle. All angles are equal And each angle has dimensions
=180°/3=60°
The angle of the straight line = 180°
so The obtuse angle of the lower isosceles triangle is 180°-60°=120°
The angles at the base of the isosceles triangle are equal
so 2x° = 180°-120°
2x°=60°
x°=60°/2
x°=30°

Rose went on a shopping trip to Richmond. She purchased a calculator originally priced at $100 but discounted 80%. If sales tax in Richmond is 15%, what was the total cost? $
Answers
Answer:
The total cost is [tex]\$23[/tex].
Step-by-step explanation:
Given: Original price of calculator is [tex]\$100[/tex], discount is [tex]80\%[/tex] and the sales tax is [tex]15\%[/tex].
To find: The total cost
Solution:
We have,
Original price of calculator[tex]=\$100[/tex]
Discount [tex]=80\%[/tex]
Sales tax [tex]=15\%[/tex]
Now, first we need to find the cost after applying the discount.
So, discount [tex]=\frac{80}{100}\times100=\$80[/tex]
Therefore, the cost after applying the discount
[tex]=\$100-\$80=\$20[/tex]
Now, we have to find the sales tax. Therefore,
Sales tax [tex]=\frac{15}{100}\times20=\$3[/tex]
So, the total cost is [tex]\$20+\$3=\$23[/tex].
Hence, the total cost is [tex]\$23[/tex].

$23

Simplify by dividing by 20.

Some number was divided into 42. This quotient was then multiplied by 8,after which the resulting product was added to 10. Given this sum totalled to 34,find the initial number.
Answers
Answer:
126
Step-by-step explanation:
In order to find the initial number, we need to create the expression that is being mentioned and solve for the initial value by applying the opposite expressions to isolate the variable.
(((x / 42) * 8) + 10) = 34 ... subtract 10 from both sides
((x / 42) * 8) = 24 ... divide both sides by 8
(x / 42) = 3 ... multiply both sides by 42
x = 126
Finally, we can see that the initial value was 126
You want to limit the amount of television you watch to an average of at most 2 hours a week during and eight week period. How many hours x can you watch in the eight weeks to meet your goal.
Answers
Answer:
x = 16hours
Step-by-step explanation:
Given
Total number of hours to watch the television a week is 2 hours, that is;
2hours =1 week
We are to find the number of hours to watch in eight weeks to meet the goal
x hours = 8 weeks
Divide both expressions;
2/x = 1/8
Cross multiply
1 * x = 2*8
x = 16
Hence he will use 16hours to watch the television in 8 weeks

A recipe for banana oat muffins calls for 3/4 cups of oats. You need to triple the recipe to make enough for your whole family. How much oats do you need?
Answers
Answer: 2 and 1/4 cups of oats (9/4 cups of oats)
Step-by-step explanation:
We know that, for the recipe, we need 3/4 cups of oats.
Now, you want to triple the recipe (then you need to use 3 times more ingredients).
This means that, if for the recipe you needed 3/4 cups of oats, when we triple that we have:
3*(3/4 cups) = 9/4 cups
This means that you need to use 9/4 cups of oats.
And we could also write this as:
9/4 cups = 8/4 cups + 1/4 cups = 2 + 1/4 cups of oats.

The octal numeral system is a base 8 positional system that uses the symbols 0,1,2,3,4,5,6,7. Write each base 8 number as a base 10 number. 12 and 117
Answers
Step-by-step explanation:
(12) in base 8
= (1 * 8¹ + 2 * 8⁰) in base 10
= (8 + 2) in base 10
= 10 in base 10.
(117) in base 8
= (1 * 8² + 1 * 8¹ + 7 * 8⁰) in base 10
= (64 + 8 + 7) in base 10
= 79 in base 10.
Using octal numeral system, 12₈ number as 10₁₀ and (117)₈ number as (79)₁₀.
What is octal numeral system?Octal numeral system has "a base of 8 and uses the number from 0 to 7".
According to the question,
a) (12)₈
= (1 * 8¹ + 2 * 8⁰)₁₀
= (8 + 2)₁₀
= 10₁₀.
b) (117)₈
= (1 * 8² + 1 * 8¹ + 7 * 8⁰)₁₀
= (64 + 8 + 7)₁₀
= (79)₁₀
Hence, using octal numeral system, 12₈ number as 10₁₀ and (117)₈ number as (79)₁₀.
