Answer:
4 times
Step-by-step explanation:
Area of circle A
Area of circle B
How many times larger is the area of circle A than circle B
therefore circle A is 4 times larger than circle B in accordance with its area
In the sentence "A piano, an old upright, had been stored in the basement", the correct appositive phrase is "an old upright". So the correct option in regards to the given question is option "d". Appositive phrase is actually a noun phrase. It actually renames a noun that is right beside it. It can either be a long or short combination of words, depending on the sentence in which it is used. Actually an appositive is a noun. Appositives will always be accompanied with a comma or brackets or dashes. Appositives are often introduced separately to the sentence.
I had the same question. I picked D
Answer:
$3 max
Step-by-step explanation:
Charge= b, Customer= c, Revenue= r
r= bc, currently, r= 16*10= $160
We know that: b+1 ⇒ c-2 and the target is r ≥ 130
So, this will all be reflected as:
b=10+x ⇒ c= 16-2x
- (10+x)(16-2x) ≥ 130
- 160 -20x +16x - 2x² ≥ 130
- -2x² - 4x + 30 ≥ 0
- x² + 2x -15 ≤ 0
- (x+1)² ≤ 4²
- x+1 ≤ 4 (negative value not considered)
- x ≤ 3
As we see the max increase amount is $3, when the revenue will be:
(10+3)*(16-3*2)= 13*10= $130
Step-by-step explanation:
x+(x+2)+(6x+10)= 180⁰.....(sum of angles in a triangle)
Open the brackets by +1
x+x+2+6x+10. =. 180⁰
2x+6x+10+2. =. 180⁰
8x+12. =. 180⁰
8x. =. 180⁰-12⁰
8x. =. 168
x. =. 168/8
x. =. 21
x+2=2+21=23
6x+10=6×21+10=126+10=136
A+B+C=180⁰
21⁰+23⁰+136⁰=180⁰
180⁰ =180⁰
