Answer:
On the number line, the y would have to be 5 or bellow.
Step-by-step explanation:
180-24=156
156/2=78
(78+24)+78=180
Hope this helped :)
Answer:
the question is missing the numbers, so I looked for a similar one and found that screens back in 2017 had a 16:9 ratio and since then it changed to 18.5:9 ratio
the area of the screen is b x a x 0.5
we can form triangles:
old aspect ratio (16:9):
a = 1.778b
h = √(a² + b²)
5.8 = √[(1.778b)² + b²]
5.8 = √(3.16b² + b²)
5.8² = 4.16b²
33.64 = 4.16b²
b² = 33.64 / 4.16 = 8.0865
b = √8.0865 = 2.8437
a = 2.8437 x 1.778 = 5.056
area = 2.8437 x 5.056 x 0.5 = 7.19 in²
new aspect ratio (18.5:9):
a = 2.0556b
h = √(a² + b²)
5.8 = √[(2.0556b)² + b²]
5.8 = √(4.2253b² + b²)
5.8² = 5.2253b²
33.64 = 5.2253b²
b² = 33.64 / 5.2253 = 6.4379
b = √6.4379 = 2.5373
a = 2.5373 x 2.0556 = 5.2157
area = 2.5373 x 5.2157 x 0.5 = 6.62 in²
the actual screen area decreased by 0.57 in² or 7.93%
Answer:
1) 350
2) 195.83
Step-by-step explanation:
<h3>#1. </h3>
Tuition fee = $12, 000 per year.
30% of it's being paid off by the scholarship, so she'll have to pay:
She'll have to pay $ 8400 by herself, her savings.
If she's saving $ 8400 for two years, she's actually saving $ 8400 for 24 months!
for one month, it'll be
= 8400/ 24
= $ 350 per month
<h3>#2</h3>
one year fee = $ 10, 700
uncle pays half of it, I.e., 10700/ 2
= $ 5, 350
he gets a grant for $ 3,000
so, the part of the fee he ain't paying
= 5,350 + 3000
= $ 8,350
So, he'll have to save:
= 10,700 - 8,350
= $ 2,350
that is per year,
for per month = 2350/ 12
= $ 195.83
Answer:
Step-by-step explanation:
Scientific notation is a quick way to represent a number using powers of base ten. This notation is used to be able to express very large or very small numbers very easily.
The numbers are written as a product:
a * 10ⁿ
where:
- a is a real number greater than or equal to 1 and less than 10, to which a decimal point is added after the first digit if it is a non-integer number.
- n = a whole number, which is called an exponent or an order of magnitude. Represents the number of times the comma is shifted. It is always an integer, positive if it shifts to the left, negative if it shifts to the right.
Comparing what is equal to these two numbers when they are written in scientific notation you can see that the value of a is such that 1 ≤ a <10
Comparing what is different from these two numbers when they are written in scientific notation, you can see that the value of the exponent n in both numbers is different, one being positive, indicating that it is a very large number, and the other negative, indicating that it is It is a very small number that is between 0 and 1.
