there are six red marbles and 11 orange marbles in a bag. You randomly choose one of the marbles. What is the probability of choosing a red marble?

Answer:

x=2 y=16 so (2,16)

Step-by-step explanation:

y=10x-4 --> 8x=10x-4

                  -10x -10x

-2x=-4

-2/-2x -4/-2

x=2

y=10x-4 --> y=10(2)-4

y=20-4

y=16

Answer:

2 ; 16

Step-by-step explanation:

y = 8x _
y = 10x - 4

___________
0=2x-4

4=2x

x=2

=> y=8*2=16

a. Based on the AA similarity theorem, Gilligan can conclude that, ΔABC ~ ΔSDC.

b. To the nearest tenth of a foot, the distance from the ship to the shore is: 847.8 ft.

The ratios of the corresponding sides of two triangles that are similar are equal.

Two triangles with two pairs of congruent angles are similar to each other based on the AA similarity theorem.

a. In ΔABC and ΔSDC, there are two pairs of congruent angles - ∠DCS ≅ ∠BCA (vertical angles) and ∠ABC ≅ ∠SDC (right angles)

Therefore, based on the AA similarity theorem, Gilligan can conclude that, ΔABC ~ ΔSDC.

b. AB = 150 ft

Distance from the ship to the shore = SD = ?

DC = 130 ft

CB = 23 ft

Thus:

AB/SD = CB/DC

Substitute

150/SD = 23/130

SD = (150×130)/23

SD = 847.8

Thus, to the nearest tenth of a foot, the distance from the ship to the shore is: 847.8 ft.

Step-by-step explanation:

Jim would have saved 50,646 in 4 years

Simple interest is a method for figuring out how much interest was paid on a sum of money during a specific time period at a specific rate. Simple interest has a constant principle amount. Simple interest is a clear-cut and simple method for computing financial interest.

We have,

P = $84,410.

R= 15%

T = 4 years

Using Simple Interest

SI = (P x R x T) / 100

SI = (84410 x 15 x 4)/100

SI = 5,064,000

So, the amount is

= 84,410 + 5,064,000

= 5,149,010

Answer:

use this formula

Step-by-step explanation:

Answer:

Step-by-step explanation:

To test if this is a right triangle, let's test these side lengths with the Pythagorean Theorem.

a^2 + b^2 = c^2

c is the hypotenuse, the longest side of a right triangle.

a and b are the legs of the right triangle.

a = 7

b = 15

c = 17

7^2 + 15^2 = 17^2 ?

49 + 225 = 289 ?

274 ≠ 289

Thus, this triangle is not a right triangle since it does not satisfy the Pythagorean Theorem.

Answer:

[tex]\frac{24}{a}[/tex] - b

[tex]\frac{21}{a}[/tex]-[tex]\frac{b}{4}[/tex]

b - [tex]\frac{2}{3}[/tex]a

25 - 2b

5b - 10a

Step-by-step explanation:

a = 3 and b = 8

Plug in a and b into your equations.

25 - 2(8) = 25 - 16..........9

[tex]\frac{8-2}{3}[/tex] = [tex]\frac{6}{3}[/tex]..........2

5(8) - 10(3) = 40 - 30..........10

[tex]\frac{24}{3}[/tex] - 8 = 8 - 8..........0

[tex]\frac{21}{3}[/tex] - [tex]\frac{8}{4}[/tex] = 7 - 2..........5

8 - [tex]\frac{2}{3}[/tex](3) = 8 - 2..........6

Then you order least to greatest.

Step-by-step explanation:

The two relations can be written in general form using the given variable definitions as ...

  5x +7y -57.40 = 0

  4x +2y -32.60 = 0

The solution using the cross-multiplication method is ...

  d1 = (5)(2) -(4)(7) = 10 -28 = -18

  d2 = (7)(-32.60) -(2)(-57.40) = -228.20 +114.80 = -113.40

  d3 = (-57.40)(4) -(-32.60)(5) = -229.60 +163 = -66.60

  x = d2/d1 = -113.40/-18 = 6.30

  y = d3/d1 = -66.60/-18 = 3.70

The cost of 1 sandwich is $6.30.

The cost of 1 burrito is $3.70.

Answer:

8x^2-22x+15

Step-by-step explanation:

Multiply them together

Answer:

There are many, many, different expressions equivalent, but if you distribute them together you come up with:

8x² - 22x + 15

Step-by-step explanation:

When distributing (4x–5) (2x-3) we should end up with four values, and then add them together.

[] The outside numbers of 4x and -3

-> 4x * -3 = -12x

[] The inside numbers of -5 and 2x

-> -5 * 2x = -10x

[] The left numbers of 4x and 2x

-> 4x * 2x = 8x²

[] The right numbers of -5 and -3

-> -5 * -3 = 15

Now we can add them together;

-12x + -10x + 8x² + 15

8x² - 22x + 15

Answer:

y-0 = 4/5(x-2)

Explanation:

0 is the y point so it goes in the y-y1 spot. The m or the slope goes into the m spot by the parenthesis. The 2 goes into the spot of the m-m1. One thing that is important is that when plugging in the point into the equation is to always put in the inverse. So if 3 was the y point, the equation would be y-3, if it was a negative point it would be, y + 3.
