Step-by-step explanation:
1 bracelet costs $7
5 bracelets is 7*5=35
As we can see with the numbers they gave us every bracelet costs 7 dollars, 1 =7, 2=14 and so on. With this information we can just take the number 5 and multiply it by 7 which would equal 35. Or you could add 7 to 21 and then 7 to 28. Whichever one works for you.

it cost 0.60 cents to run a fan for 4 hours how much does it cost to run the fan for 6 hours I need an answer asap
Answer:
$0.90
Step-by-step explanation:
So first you need to find the rate (showing how much money it costs to run for 1 hour) so you get 0.60 and divide it by 4 and its 0.15, then multiply 0.15 by 6 and get 0.90
If y = -x and x = -14, find y.
Answer:

This table shows the profit for a company (in millions of dollars) in different
years.
The quadratic regression equation that models these data is
y=-0.34x2 + 4.43x + 3.46. Using the quadratic regression equation, what
was the predicted profit in year 10?
A. $44.36 million
B. $10 million
C. $15 million
D. $13.76 million
Answer:
D. $13.76 million is the correct answer :)
Step-by-step explanation:
The solution is, $13.76 was the predicted profit in year 10.
Here, we have,
Given : the equation is,
y=-0.34x^2 + 4.43x + 3.46.
To Find : Using the quadratic regression equation, what was the predicted profit in year 8
Solution :
y=-0.34x^2 + 4.43x + 3.46.
Where y is profit and x is year
Substitute x = 10
y=-0.34* 10^2 + 4.43*10+ 3.46.
or, y = 13.76
So, Option D is true
Hence the predicted profit in year 10 is $13.76.

The three lengths 3, 10, 7 create a triangle.
Answer:
false
Step-by-step explanation:
I assume this is a true/false question.
The answer would be 'false'.
For 3 segments to make a triangle, each single side must be LESS than the sum of the other two.
Here, that is not the case. The '10' side is not less than 3+7.

Find the sum of the first 35 terms of the following series, to the nearest integer.
3, 11, 19...
=======================================================
Explanation:
The sequence {3,11,19,...} is arithmetic since we are adding 8 to each term to get the next one
3+8 = 1111+8 = 19etc. This means the common difference is d = 8.
The first term is a = 3
Let's use this formula
S = n*(2*a + d(n - 1) )/2
so we can find the sum of the first n terms. In this case, n = 35
So,
S = n*(2*a + d(n - 1) )/2
S = 35*(2*3 + 8(35 - 1) )/2
S = 35*(6 + 8(34))/2
S = 35*(6 + 272)/2
S = 35*(278)/2
S = 35*139
S = 4865
[tex]4865[/tex] is the the sum of the first [tex]35[/tex] terms of the following series [tex]3, 11, 19...[/tex]
What is arithmetic sequence?
An arithmetic progression or arithmetic sequence is a sequence of numbers such that the difference between the consecutive terms is constant. For instance, the sequence 5, 7, 9, 11, 13, 15.. . is an arithmetic progression with a common difference of 2
The sequence [tex]{3,11,19,...}[/tex] is arithmetic since we are adding [tex]8[/tex] to each term to get the next one as shown below:
[tex]3+8 = 11\\11+8 = 19[/tex]
This means the common difference is [tex]d = 8.[/tex]
The first term is [tex]a = 3[/tex]
Number of terms [tex]=n=35[/tex]
Sum of the series
[tex]=\frac{n}{2} (2a+(n-1)d)[/tex]
[tex]=\frac{35}{2} (2[/tex]×[tex]3+34[/tex]×[tex]8)[/tex]
[tex]=35[/tex]×[tex]139[/tex]
[tex]=4865[/tex]
Hence, we can conclude that the sum of the first [tex]35[/tex] terms of the following series is [tex]4865[/tex]

Given :
∠F = ∠J∠D = ∠H∠E = ∠ISum of all angles in a triangle = 180°
Which means :
41 + 20 + 15x - 1 = 180[tex] = \tt61 + 15x - 1 = 180[/tex]
[tex] =\tt 61 - 1 + 15x = 180[/tex]
[tex] =\tt 60 + 15x = 180[/tex]
[tex] = \tt15x = 180 - 60[/tex]
[tex] =\tt 15x = 120[/tex]
[tex] = \tt \: x = \frac{120}{15} [/tex]
[tex] =\tt x = 18[/tex]
Thus, the value of x = 18Measure of angle 15x-1 :
[tex] = \tt15 \times 8 - 1[/tex]
[tex] =\tt120 - 1[/tex]
[tex] =\tt 119[/tex]
Thus, the measure of angle 15x-1 = 119°
Let us place 8 in the place of x to see if we have found out the correct measure of the angles :
[tex] = \tt40 + 21 + 119 = 180[/tex]
[tex] = \tt61 + 119 = 180[/tex]
[tex] =\tt 180 = 180[/tex]
Since the measures of all the angle sum up to form 180°, we can conclude that we have found out the correct measure of each of the angles.
Therefore, the value of x = 8

Answer:
1a. 3y = 18
1b. y + 7 = 18
1c. 2y + 4 = 18
Step-by-step explanation:
In each case, let's take the red boxes to be constant why the the green boxes represents the variable, y.
Thus,
1a. There are only 3 green boxes which gives us 18, therefore, the equation that expresses this would be:
3y = 18
1b. We have 7 red boxes which represents the constant, 7.
We also have 1 green box which represents the variable, y. Therefore, the equation that expresses this would be:
y + 7 = 18
1c. We have 4 red boxes = 4
We have 2 green boxes = 2y
Therefore, we would have:
2y + 4 = 18

Could you help me please? This is a thing for my sons math homework.
Answer:
See below.
Step-by-step explanation:
I've never seen one asked quite this way, but I think I have it figured out.
The objective here is to get the right answer for each square. The answer is either the one next to the 'x', which means you put an 'x' in the tic-tac-toe square or the answer is the one next to the 'O', which means you put an 'O' in the tic-tac-toe square.
I will number them boxes 1-3 on the top row, 4-6 for the next, and 7-9 for the bottom row.
Box 1: In a fraction, you subtract the bottom exponent from the top exponent, so the proper exponent is 10 - 2 = 8. That is an O for g^8.
Box 2: A power raised to a power - multiply the exponents. 2*6=12. That is an X for m^12 for box 2.
Box 3: for multiplying the same base, you add the exponents. 4+5=9. That gives us y^9, which is a X for box 3.
Box 4: j is a factor four times, so that is j^4. That puts an O in Box 4.
Box 5: In a fraction, you subtract the bottom exponent from the top exponent, so we get -2 - (-6) = -2 + 6 = 4. The correct expression is h^4, so we have an X for box 5.
Box 6: A power to a power, you multiply the exponents so the first part becomes m^8. Now we have m^8 * m^5. For multiplying the same base, you add the exponents. 8+5=13. That gives us m^13, which puts an O in box 6.
Box 7: The top is a power to a power so we multiply the exponents. 4*5=20. The top is b^20.
On the bottom, for multiplying the same base, you add the exponents. 2+3=5, so the bottom is b^5.
Now we have a fraction, (b^20)/(b^5). In a fraction, you subtract the bottom exponent from the top exponent, so we have 20 - 5 = 15, and thus b^15. That gives us an X for box 7.
Box 8: A fraction IS a division, so we do divisons and fractions the same way. The p^3 on the left is the top (numerator) and the p^2 part is the bottom (denominator). So 3-2=1. But P^1 is just P, so we have an O for box 8.
Box 9: For the numerator, it is a power to a power so we multiply the exponents and get k^12.
For the denominator, we are multiplying the same base, so you add the exponents. 7 + (-5) = 2, and we get k^2 for the denominator
Now we have the fraction of k^12 OVER k^2. In a fraction, you subtract the bottom exponent from the top exponent. 12-2=10. We get k^10, giving us an X for box 9.
So here is what we get for tic-tac-toe.
0 X X
O X 0
X O X
We get 3 in a row in boxes 3, 5, and 7. The exponents in those problems are 9, 4, and 15 respectively. The product of thse 3 numbers is 540.
This was a LOT of steps, so I encourage you to check every little multiplication and addition I did.
Hope this helps.
