Answer 1

Answer: 234

=========================================================

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.

I think the answer is 6

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.

I figured out the first part only need help with the second part.I need help ASAP

Answers

Answer:

the answer would be 112.5min

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

Yes so well done for establishing
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

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:

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.

In a particularly sunny month, Solaire's solar panels generated 110%, percent as much power as expected.
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

A property's value decreased by 15%. If is was worth 189,000, what is worth now?

Answers

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 decrease

Percent 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.
