Answer:

sum of ratio term = 2+5

= 7

first we have to find the value of 2 in ratio term

50 x 7/2

175

now, we have to find value of 5 in ratio term

50 x 7/5

70

addition of both the value of 2 and 5 in ratio term

175+70

245

hence, your answer is 245 marbles

Answer:

1040

Step-by-step explanation:

substitute the given information

h = 36

s = 10,000

E = 15 x 36 + 0.05 x 10,000

E = 540 + 500 = 1040

Answer:

21

Step-by-step explanation:

15-(-6)=21

Answer:

21

Step-by-step explanation:

Since (-6) is a negative number, we will have to cancel it out with positive 6 to get to 0. Then you add 6 and 15 to get 21.

Answer: The 12th term is 46x -25

Step-by-step explanation:

It is increasing by 4x and decreasing by 3 through each term, this represents the d. a1 has already been identified as 2x +8, so you just have to write down the formula and the solve form there by plugging in the 12 in (n-1) to find the answer.

Answer:

okay so can you award me brainlyist this took me awhile

Step-by-step explanation:

1: 2/3 * 42 = 28

2: 5/12 * 26 = 10 5/6

3: 11/15 * 20 = 14 2/3

4: 3/8 * 54 = 20 1/4

Based on the special angles formed by transversal and parallel lines, the missing variables are:

z = 86°

y = 75°

x = 105°

w = 94°

Thus:

z = 86° (vertical angles)

y = 75° (alternate interior angles)

x = 180 - 75 = 105° (supplementary)

w = 180 - 86 = 94° (supplementary)

The value of n when the sum is 30 is equal to 5.

Given the following data:

To determine the value of n when the sum is 30:

Mathematically, the sum of the first n consecutive even numbers is given by this formula:

[tex]S=n^2+n[/tex]

Where:

Substituting the given parameters into the formula, we have;

[tex]30=n^2+n\\\\n^2+n-30=0\\\\n^2 +6n-5n-30=0\\\\n(n+6)-5(n+6)=0\\\\(n+6)(n-5)=0[/tex]

n = -6 or 5.

Since, n > 2;

n = 5.

Answer:

12 Years

Step-by-step explanation:

216 - 168 = 48 (new deer every 3 years)

48 / 3 = 16 (new deer every 1 year)

Since we end at the year 2009, we need to start counting from 312 deer.

500 - 312 = 188 (Needed new deer)

188 / 16 = 11.75 (Years needed)

11.75 rounded to the year (whole number) is 12.

Answer:

[tex](-\frac{3}{2},\frac{9}{4})[/tex]

Step-by-step explanation:

A normal line is a line perpendicular to the tangent line, so we must take the derivative of the function to find the slope of the tangent line, and then take the opposite reciprocal of this slope, to find the slope of the normal line. The equation of a normal line will be in the form of [tex]y=mx+b[/tex]:

[tex]f(x)=x^2\\\\f'(x)=2x\\\\f'(1)=2(1)\\\\f'(1)=2[/tex]

Hence, the opposite reciprocal is [tex]-\frac{1}{2}[/tex], which is our slope for the normal line. Now, we find the y-intercept by plugging in the given coordinate point [tex](1,1)[/tex] since [tex]f(1)=1^2=1[/tex]:

[tex]y=-\frac{1}{2}x+b\\\\1=-\frac{1}{2}(1)+b\\ \\1=-\frac{1}{2}+b\\ \\b=\frac{3}{2}[/tex]

Thus, the equation of the normal line is [tex]y=-\frac{1}{2}x+\frac{3}{2}[/tex]. Using this information, we can now find the coordinates where the normal of the curve at x=1 meets the curve again:

[tex]x^2=-\frac{1}{2}x+\frac{3}{2}\\ \\ x^2+\frac{1}{2}x-\frac{3}{2}=0\\ \\ 2x^2+x-3=0\\\\(x-1)(2x+3)=0\\\\x=1,\: x=-\frac{3}{2}[/tex]

Since we only care about [tex]x=-\frac{3}{2}[/tex] since [tex]x=1[/tex] was already accounted for, the y-coordinate would be:

[tex]y=x^2\\\\y=(-\frac{3}{2})^2\\\\y=\frac{9}{4}[/tex]

Therefore, the coordinates are [tex](-\frac{3}{2},\frac{9}{4})[/tex].

In the graph attached below, you can see the tangent line [tex]y=2x-1[/tex] and how it is perpendicular to [tex]y=\frac{1}{2}x-\frac{3}{2}[/tex].
