Answer:

the slope is 4

Step-by-step explanation:

look at the dotted lines. to determine the slope with a graph you must use rise over run. this is the fastest way to determine the slope using a graph.

A bag contains 9 red marbles,7 blue marbles, and 4 green marbles. A randomly drawn marble is blue?

Elena-2011 [213]

Answer: $\frac{7}{20}$

Step-by-step explanation:

If this is asking for the probability of randomly drawing a blue marble then it'll be however many blue marbles (what you're trying to find) out of the total number of marbles

Blue marbles: 7

Total marbles: 20

$\frac{7}{20\\}$

Use the graph shown to complete the following sentence. when x = -3, then y = ___.<br>

Alenkinab [10]

Answer:

y = -6

Step-by-step explanation:

We are trying to find the y-value when x = -3.

We see from our graph and linear equation that when x = -3, y = -6.

Therefore, our answer is -6.

PLSSSSSSSS HELLPPPPPP.......Which triangle’s unknown side length measures StartRoot 53 EndRoot units?

Orlov [11]

The right answer is Option 2: A right triangle with side length of √47 and hypotenuse of 10.

Step-by-step explanation:

We know that;

$a^2 + b^2 = c^2$

We will put the unknown length as √53 to check the solution.

Option 1: a = 6 , b = √53 , c = √91

$(6)^2+(\sqrt{53})^2=(\sqrt{91})^2\\36+53=91\\89\neq 91$

Option 2: a=√47, b = √53, c = 10

$(\sqrt{47})^2+(\sqrt{53})^2=(10)^2\\47+53=100\\100=100$

Option 3: a = √19, b=√53, c= √34

$(\sqrt{19})^2+(\sqrt{53})^2=(\sqrt{34})^2\\19+53=34\\72\neq 34$

Option 4: a=√73, b=√53, c=20

$(\sqrt{73})^2+(\sqrt{53})^2=(20)^2\\73+53=400\\126\neq 400$

Option 2 satisfies pythagoras theorem.

Therefore;

The right answer is Option 2: A right triangle with side length of √47 and hypotenuse of 10.

In right trapezoid MNPQ

Gala2k [10]

Answer:

about 252.78 ft

Step-by-step explanation:

Define angle QMP as α. Then ...

MN = 60·sin(α)

NP = 60·cos(α)

area MPN = (1/2)(MN)(NP) = 1800sin(α)cos(α)

PQ = 60tan(α)

area MPQ = (1/2)(MP)(PQ) = 1800tan(α)

The ratio of areas is 2.5, so we have ...

1800tan(α) = 2.5·1800sin(α)cos(α)

1 = 2.5cos(α)² . . . . . . divide by 1800tan(α)

cos(α) = √0.4 . . . . . . solve for cos(α)

Then the perimeter is ...

Perimeter = MN +NP +PQ +QM = 60sin(α) +60cos(α) +60tan(α) +60/cos(α)

= 60(sin(α) +cos(α) +tan(α) +sec(α))

= 60(0.774597 +0.632456 +1.224745 +1.581139)

= 60(4.212936) = 252.776

The perimeter of the trapezoid is about 252.776 feet.

_____

With perhaps a little more trouble, you can find the exact value to be ...

perimeter = (6√10)(7+√6+√15)
