Answer:

2.) (3,-2)

3.) (5,3)

4.) *Still trying to solve*

Step-by-step explanation:

2.)

Step 1.

   5x + 4y = 7

    3x - 4y = 17

+ ------------------

    8x      =   24

    8              8

         x = 3

Step 2.

    5x + 4y = 7

    5(3) + 4y = 7

     15 + 4y = 7

     -15          -15

      4y =  -8

      4        4

        y = -2

Final Answer: (3,-2)

3.

Step 1.

    4x + 5y = 35

         x = 2y - 1

   4(2y - 1) + 5y = 35  

    8y - 4 + 5y = 35

      13y - 4 = 35

            +4     +4

        13y = 39

        13      13

        y = 3

Step 2.

    x = 2y - 1

    x = 2(3) - 1

     x = 6 - 1

     x = 5

Final Answer: (5,3)

I do apologize that I couldn't find the solution to 4.) if I do I will edit this answer

I hope this helps!

Answer:

13/36

Step-by-step explanation:

1 - 2/3 equals 1/3 which is inside the parenthesis

square the number in parenthesis (1/3) and it equals 1/9

multiply the 2 fractions 1/4 and 1/9 to get 1/36

finally add 1/3 with 1/36

12/36 + 1/36 would equal 13/36

Answer:

kiwis = $1.5

mangoes = $2.25

Step-by-step explanation:

Two equations can be derived from the question

2m + 3k = 9 equation 1

5m + 2k = 14.25 equation 2

m = mangoes

k = kiwis

multiply equation 1 by 5 and 2 by 2

10m + 15k = 45 equation 3

10m +4k = 28.5 equation 4

Subtract equation 4 from 3

11k = 16.5

k = 1.5

Substitute for k in equation 1

2m + 3(1.5) = 9

2m + 4.5 = 9

2m = 4.5

m = 2.25

Answer:

This is about your opinion, not mine, but here's my opinion.

Don't copy and paste because anything can be found with good filters.

Essentially, just paraphrase or something.

Step-by-step explanation:

I prefer standard notation when calculating with small digits under 6 zeros because it is more visually simpler to view. When a number is involved with more digits, I prefer scientific notation because it is unlikely that I will lose track of how many digits there are.

Answer:

(x+6)^2 +(y-4)^2 = 49

Step-by-step explanation:

The equation of a circle is given by

(x-h)^2 +(y-k)^2 = r^2 where (h,k) is the center and r is the radius

(x- -6)^2 +(y-4)^2 = 7^2

(x+6)^2 +(y-4)^2 = 49

In the given question, it is given that  ramp is 17 feet long, rises 8 feet above the floor, and covers a horizontal distance of 15 feet.

And we have to find the value of tan B.

And tangent of any angle is equal to the ratio of vertical by horizontal. That is:

tanB=8/15

And that's the required missing ratio for tan B.

Answer:

The ratio of sin b to cos b is equal to tan B.

Step-by-step explanation:

coefficient of x

Answer:

The answer above me is correct, the slope is 1/2.

Step-by-step explanation:

It is the coefficient of x.

Answer:

Step-by-step explanation:

We don't need choices to find out the correct answer. Solve this problem by completing the square. Begin by setting the quadratic equal to 0 and moving over the constant, like this:

[tex]-x^2+2x=-1[/tex] and factor out the -1 in front of the x-squared, since the leading coefficient HAS to be a 1:

[tex]-1(x^2-2x)=-1[/tex] Now take half the linear term, square it, and add it to both sides. Our linear term is -2. Half of -2 is -1, and squaring that gives us 1. So we add a 1 into both sides. But that -1 out front there on the left is a multiplier, so what we actually added in was -1(1) which is -1:

[tex]-1(x^2-2x+1)=-1-1[/tex]

On the left side we have a perfect square binomial, which is why we do this, and on the right side we have -2:

[tex]-1(x-1)^2=-2[/tex] and we can move that constant back over and set the quadratic back equal to y:

[tex]y=-1(x-1)^2+2[/tex]  which gives us a max height of 2.

(If this was modeling parabolic motion, we would know that the time it takes to get to that max height is 1 second. The vertex of this parabola is (1, 2))

Answer:

A. ¹/27

Step-by-step explanation:

✔️Volume of large sphere = ⁴/3πr³

r = 18.6 in.

Volume of large square = ⁴/3*π*18.6³ = 26954.26 in.³

✔️Volume of small sphere = ⁴/3πr³

r = 6.2 in.

Volume of small sphere = ⁴/3*π*6.2³ = 998.31 in.³

✔️Ratio of the volume of the smaller sphere to the larger sphere = 998.31 : 26954.26

= 1 : 27

Therefore, the volume of the large sphere is ¹/27 of the volume of the small sphere.

Financial Freedom

Step-by-step explanation:

In my personal opinion, the biggest reason/incentive for saving would be Financial Freedom. This is the ability to not have to depend on a full-time job in order to survive and be able to live off of the passive income being produced by the money that you saved. If you save enough money and invest it correctly you can live off of the interest that is being generated from those investments. This allows you to not have to work a full-time job and instead free's up your time to pursue meaningfull hobbies or even travel. I believe that is true freedom and it is something that motivates me to save money.

Step-by-step explanation:

Answer:

He will need at least 657,142.86

Step-by-step explanation:

Determine how much commission he needs

60000-14000

46000

Commission is 7%

Let x be the sales

x*7% = 46000

x*.07 = 46000

Divide each side by .07

x = 46000/.07

x =657142.85714

Rounding to the nearest cent

x = 657,142.86

Answer:

find the value of:Cos = 0.54

Answer:

rounding is used to make long/rough calculations cleaner or easier

Step-by-step explanation:

Answer:

Rounding is used in instances where you can only have a limited number of digits or You must round to the nearest digit.

Step-by-step explanation:

For example lets say i have the problem 12.5 + 4 + 3.2.

I am told to round up to the nearest whole number.

After adding all the numbers up, I find I have 19.7 since the tenths place is a 7, I would round up leaving my final answer as 20.
