Answer:

∠ A = 60°

Step-by-step explanation:

Using the sine ratio in the right triangle

sinA = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{BC}{AC}[/tex] = [tex]\frac{13}{15}[/tex] , thus

∠ A = [tex]sin^{-1}[/tex] ( [tex]\frac{13}{15}[/tex] ) ≈ 60°

------------------------------------------------

Using the cosine ratio in the right triangle

cosR = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{RT}{RS}[/tex] = [tex]\frac{8}{10}[/tex] , thus

∠ R = [tex]cos^{-1}[/tex] ( [tex]\frac{8}{10}[/tex] ) ≈ 36.9° ( to 1 dec. places )

answer: each apple cost 2$

Answer:

$4.50.

Step-by-step explanation: Since the market is selling 8 apples for $4, we can determine that one apple is 50 cents. Knowing that information, we can apply that same rule to 9 apples, resulting in a total of $4.50. Hope this answered your question.

Answer:

Hello!!! Princess Sakura here ^^

Step-by-step explanation:

So first you have to plug in what you know...

[tex]3x+y>3\\3(\frac{3}{4})+(0)>3\\\frac{9}{4}+0>3\\\frac{9}{4} >3[/tex]

If it's hard to look at it that way you should make it look like this...

[tex]2\frac{1}{4} >3[/tex]

Now when you look at it you can tell that it's false, so [tex](\frac{3}{4},0 )[/tex] is not a solution f this inequality.

Answer:

I think its "Maria selected a multiple that is not the least of the common multiples"

Step-by-step explanation:

I think the real answer would be 30 because it the lowest number that they both share....

Answer: the answer is d, she selected a multiple that is not a least common multiple. The least common multiple is the number both sets of numbers share, which  would be 30.

Answer:

y= -3x + 7:)

Step-by-step explanation:

Hope this helps!

Answer:

y = - 3x + 7

Step-by-step explanation:

The equation of a line in slope- intercept form is

y = mx + c ( m is the slope and c the y- intercept )

Here m = - 3 , thus

y = - 3x + c ← is the partial equation

To find c substitute (4, - 5) into the partial equation

- 5 = - 12 + c ⇒ c = - 5 + 12 = 7

y = - 3x + 7 ← equation of line

Answer:

Step-by-step explanation:

Answer:

0.31 is greater than 0.039

Step-by-step explanation:

Given:

Superman is working at Daily Planet Newspaper P(100, 40).

Bank robbery at B(40,80).

Criminals to jail at C(130, 105).

Then fly back to the Daily Planet.

To find:

The total distance for the trip.

Solution:

Distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex]

Using distance formula, the distance between Daily Planet Newspaper P(100, 40) and place of bank robbery at B(40,80) is

[tex]PB=\sqrt{(40-100)^2+(80-40)^2}[/tex]

[tex]PB=\sqrt{(-60)^2+(40)^2}[/tex]

[tex]PB=\sqrt{3600+1600}[/tex]

[tex]PB=\sqrt{5200}[/tex]

[tex]PB=20\sqrt{13}[/tex]

Similarly,

Distance between place of bank robbery at B(40,80) and jail at C(130,105) is

[tex]BC=\sqrt{\left(130-40\right)^2+\left(105-80\right)^2}[/tex]

[tex]BC=5\sqrt{349}[/tex]

Distance between jail at C(130,105) and Daily Planet Newspaper P(100, 40) is

[tex]CP=\sqrt{\left(100-130\right)^2+\left(40-105\right)^2}[/tex]

[tex]CP=5\sqrt{205}[/tex]

Total distance for the trip = PB+ BC +CP

[tex]Trip=2\sqrt{13}+5\sqrt{349}+5\sqrt{205}[/tex]

[tex]Trip=7.2111+93.4077+71.5891[/tex]

[tex]Trip=172.2079[/tex]

[tex]Trip\approx 172.21[/tex]

Therefore, the total distance for the trip is about 172.21 units.

[tex]6 - 3x = 5x - 10x + 6[/tex]

[tex]6 - x = - 5x + 6[/tex]

[tex]6 + 5x = 6 - 3x[/tex]

[tex]6 = 6 - 3x + 5x[/tex]

[tex]6 = 6 + 2x[/tex]

[tex]2x = 6 - 6[/tex]

[tex]2x = 0[/tex]

Product of two numbers is equal to 0 if at least one of them is 0 . Since 2 is not equal to 0 , x must be equal to 0 .

Which means :-

[tex]x = 0[/tex]

Therefore , the value of x = 0.
