Explanation:
The symbol that looks like an "E" is the uppercase greek letter sigma. It's used for summation. Specifically we are adding terms of the form -4+5n. What we do is replace n with values from the set {2,3,4,...,9,10}. After evaluating each item, we add up the results to get our final answer.
If n = 2, then -4+5n = -4+5*2 = 6 which is the first term.
If n = 3, then -4+5n = -4+5*3 = 11 is the second term
and so on until you reach n = 10.
A table is a handy way to keep track of everything (see below). Adding everything in the second column leads to the final answer of 234.

HELP PLZ ND THX U?!?!?!?!?!?!?!?!?!
Answers
Answer:
U = 1
Answer = 6
Step-by-step explanation:
We can do really any number. But in this case, we are gonna do 1. So, it would look like (7 x 1) - 1. It would look like that because we know that 7u is equal to 7 times U or in this case, 7 times 1. So, we know 7 x 1 is 7. Now, we do 7 - 1 since U = 1, and we get our answer of 6.

Answers
Answer:
20%
Step-by-step explanation:
Therefore, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.
What is the percentage?
A percentage is a number or ratio expressed as a fraction of [tex]100[/tex]. It is often denoted using the percent sign, "%".
Here given that,
Mr. Reynolds is a rancher. He started with a [tex]150[/tex] cows in his herd. Due to a hole in his fence, he now has [tex]120[/tex] cows in his herd.
Number of cows Mr. Reynolds have
[tex]\frac{120}{150}[/tex] ×[tex]100=80[/tex] %
So, the number of cows Mr. Reynolds reduced is
[tex]100[/tex] % - [tex]80[/tex] % = [tex]20[/tex] %
Hence, the percentage of the number of cows in Mr. Reynold's herd reduced is [tex]20[/tex] %.

What fraction of the expected amount of power did Solaire's solar panels generate?
Answers
Answer:
I think the answer would be 11/10
Step-by-step explanation:
when simplifying a percent into a fraction you always make the denominator 100, since the percent is 110, the numerator is 110, so 110/100. From there you can take off the 0s from the ends of both and boom, 11/10, hope this makes sense!
Answer:
11/10 or 1 1/10
Step-by-step explanation:
110%/100% is equal to 11/10, or 1 1/10

Explanation:
I believe you have the equations wrong. 1 equation you can use is t=15d, and the other equation you can use is d=t/15. then if you plug 7.5 for d in one of the equations you can get the answer
T= 30
And d=2
Now we need an equation that links together.
So to get d (2) equal to t (which is 30) we need to multiply by 15.
So t = 15d
Or if you make d the subject
D = 15/t
So if this Titus walks 7.5 miles
T = 15 x distance
Time = 15 x 7.5
So the time is 112.5

Which of the following numbers is between - 3/4 and 5/8 ?
Answers
Answer:
I believe that the answer is -1/2
Step-by-step explanation:
The number which falls under the inequality -3/4 < x < 5/8 is when x = -1/2
The correct answer is Option D.
Given data:
The number x is between -3/4 and 5/8.
So, the inequality is -3/4 < x < 5/8.
When comparing fractions, we consider their relative positions based on their magnitudes. Starting from the left, -3/4 represents a point closer to negative infinity, followed by -1/2, and then 5/8, which is closer to positive infinity.
Visually, imagine the number line where -3/4 is to the left, 5/8 is to the right, and -1/2 is positioned between them. Since -1/2 is greater than -3/4 and less than 5/8, it falls within the specified range. The choice -1/2 satisfies the condition and can be identified as the number between -3/4 and 5/8.
Hence, the number is x = -1/2.

A rectangular box is designed to have a square base and an open top. The volume is to be 2048in.3
What is the minimum surface area that such a box can have?
Answers
Answer:
x=y=z in 3 dimensions. So, you have x2y=4=x3⟹x=y=3√4.
Step-by-step explanation:
Answer:
hi
Step-by-step explanation:
Let x = the length of the sides of the base and h = the height:
Volume = (area of base)(height)
V = x2h
2048 = x2h
2048/x2 = h
Surface Area = area of base + 4(area of vertical side)
SA = x2 + 4xh
Eliminate the h by using 2048/x2 = h:
SA = x2 + 4x(2048/x2)
SA = x2 + 8192 x-1
Take the derivative of SA wrt x, set it to zero, solve for x. Plug that value of x into the surface area equation to find the minimum surface area.

15% of 189000 = [tex] \frac{15}{100} \times 189000 = 28350 \\ [/tex]
So, now it's worth[tex] = 189,000 - 28,350 \\ = 160,650[/tex]
The current worth of the property is $160,650.
What is percentage?Percentage, is a relative value indicating hundredth part of any quantity.
Formula for percent decreasePercent decrease = ( decreased value/ original value) × 100
Therefore,
Decreased value = Original value - new value
According to the question
We have
Percent decrease = 15%
Original value of the property = $ 189,000
So, 15% 0f $189,000 = [tex]\frac{15}{100}[/tex] × 189000
⇒ 15% of 189000 = $28350
Therefore, the decreased value of the property = $189000 - $28350
Decreased value of property = $160,650
Hence, the current worth of the property is $160,650.
