Answer:
C: 800 x 20
Step-by-step explanation:
Basically, when you round 778 you see that the 7 and 8 are above 5, which means you round upwards. Therefore it would be best to round up to 800.
Then the 3 in 23 is below 5, meaning you round downwards. 20 Is the closest and best option.
So, C: 800 x 20 is best to do!

The flashlight you are using to find your phone is a green flashlight which isn't good for finding things in the dark. You decide to go grab your yellow flashlight instead. Which wave property differs in the two flashlights causing this difference in color? Explain.
Answer:
their wavelength
Explanation:
A wave refers to disturbances or vibrations that travel from one medium or vacuum to another in an organized way, while wavelength refers to the distance between two consecutive peaks of waves.
For example, the wavelength of green light is 550nm (nanometre), while that of yellow light is 580nm (nanometre).
This difference in the color of the flashlights is visible to the human eyes because the human eye is believed to be able to detect any wavelengths of light from 700 nanometres to about 400 nm for violet light.

Jim made $143 for 11 hours of work at the same rate how many hours would he have to work to make $91
Answer:
Step-by-step explanation:
The equation is
Salary = 11 * x Where x is the number of hours.
salary = 143
hours = 11
x = ?
143 = 11x Divide both sides by 11
143/11 = 11x/11
13 = x
So to get 143 he works for 13 dollars / hour
salary = 13 * x
salary = 91
13 x = 91
13x/13 = 91/13
x = 7
He must work 7 hours to get 91 dollars.
Jim made 143 dollar for 11 hours of work at the same rate how many hours would he have to work to make 91 dollar
✺ Explanation -:Given:
Jim made $143 for 11 hours of work.To Find:
Hours he have to work to make $91.Solution:
We can solve this question using two methods Unitary Method and Method of proportion.
Unitary Method -
For $143 he work 11 hours
For $1 he work [tex]\dfrac{11}{143}[/tex] hrs
For $91 he works [tex]\dfrac{\cancel{11}} {\cancel{143}\: \: \cancel{13}}[/tex] × [tex]\cancel{91}\: \: 7 [/tex]hrs
= 7 hours
He must work 7 hours to get $91.
[tex] \ {\rule{50mm}{3pt}}[/tex]
Method of proportion -
He work 'x' hours for $91. (x as no. of hrs)
[tex] \left[\begin{array}{c | c}\ \bf{Salary} & \bf{Number \: of \: hrs} \\ \sf{143 \: dollar} & \sf{11hrs} \\ \sf{91 \: dollar}& \sf{x}\end{array} \right][/tex]
143 : 91 :: 11 : x
Product of mean = Product of extreme
143 × x = 91 × 11
→ x = [tex]\dfrac{91 × 11}{143}[/tex] = 7hrs
He must work 7 hours to get $91.
[tex] \ {\rule{90mm}{3pt}}[/tex]

1. The first three terms and the last term of a finite arithmetic sequence are - 92,- 88. -
84, ...,12.Find the number of terms in the sequence.
A. 20
B. 25
C. 27
D. 30
The number of terms in the given arithmetic sequence is 27 so option (C) will be correct.
What is Arithmetic progression?The difference between every two successive terms in a sequence is the same this is known as an arithmetic progression (AP).
The arithmetic progression has wider use in mathematics for example sum of natural numbers.
Natural number = 1,2,3,4,5,6,7,8...
Now it has the same difference between any two consecutive terms d =2-1 = 3-2
Given the AP;
- 92,- 88, -84, ...,12.
First term (a) = -92
Common difference(d) = -88 + 92 = 4
The nth term or last term = 12
Nth term is given as ;
⇒ a + (n - 1)d
12 = -92 + (n - 1)4
n - 1 = 26
n = 27
Hence "The number of terms in the given arithmetic sequence is 27".

Solve 4/y = 2/11.
The solution is y=__ ?
Answer:
See below.
Step-by-step explanation:
4/2=2
2*11=22
y=22
-hope it helps
Answer:
22
Step-by-step explanation:
4/22 is equivalent to 2/11 because 2/11 is 5 and a half times 2. So the second one has to be 5 and a half times 4. So the answer is 4/22.

Step-by-step explanation:
We solve it by writing [tex]\frac{60}{100}[/tex] times [tex]\frac{40}{1}[/tex]
Why is it over 100? Because every percent is out of 100!
[tex]\frac{60}{100}[/tex] X [tex]\frac{40}{1}[/tex] (your equation)
60 times 40 = 2400 and 100 times 1 = 100, We get, [tex]\frac{2400}{100}[/tex],
