Which expression could be used to determine the perimeter of the triangle?

A 9x + 4
B 9(x + 4)
C 13x
D 13(x + 1)

Answer:

[tex]\frac{3}{8}[/tex]

Step-by-step explanation:

After Saturday, there was [tex]\frac{5}{8}[/tex] of the journey left. [tex]\frac{3}{5}[/tex] of that would be:

[tex]\frac{5}{8}[/tex] *  [tex]\frac{3}{5}[/tex] = [tex]\frac{15}{40}[/tex] = [tex]\frac{3}{8}[/tex] of the journey.

Thus, the answer is 3/8

Answer:

16.125 is the perimeter

Step-by-step explanation:

Multiply 15.375 × 3 because a triangle has three sides and is equilateral.

15.375 × 3 = 16.125

Have a great day!

Step-by-step explanation:

Distance between (5,-3) and (9,1)=√(9-5)^2+(1-(-3))^2

=√4^2+4^2

=√16+16

=√32 units

It's not possible to calculate the distance between these points by pythagoras theorem .We can easily calculate it by distance formula I.e.√(x2-x1)^2+(y2-y2)^2

Answer:

A) 2

Answer:

Margarita gastó $40.43.

Step-by-step explanation:

Tenemos la siguiente información.

km recorridos por Margarita

42 km - ciudad

387 km - autopista

Rendimiento del carro

1 galon cada 28 km - ciudad

1 galon cada 36 km - autopista

Hacemos el siguiente factor de conversión

Ciudad

[tex]42 km \times \frac{1\: galon}{28\: km}=1.5\: galones[/tex]

Autopista

[tex]387 km \times \frac{1\: galon}{36\: km}=10.75\: galones[/tex]

Ahoa, se sabe que 1 galon cuesta $3.30. Por lo tanto, el costo de viaje será:

Total galones = 1.5 + 10.75 = 12.25 galones

Total costo = 3.30*12.25 = $40.43.

Answer:

y = 3x + 1

Step-by-step explanation:

substitute the variables in y=mx+b

(5) = 3(-2) + b

5 = -6 + b

add 6 on each side

1 = b

Answer:

A. 44/625

Step-by-step explanation:

There are 25 marbles total. To first calculate the probability of picking a yellow marble first can be represented as 11/25, the probability of picking blue is 4/25. We multiply these to figure out the probability of finding a yellow marble and then a blue one.

11/25 x 4/25 = 44/625

Answer:

x = 5 ± √46

Step-by-step explanation:

[tex]-x^2 + 10x + 21 = 0[/tex]

Take -1 common from L.H.S.

[tex]=> -1(x^2 -10x - 21) = 0[/tex]

Take -1 to R.H.S.

[tex]=> x^2 - 10x - 21 = 0[/tex]

Solve x using quadratic formula.

[tex]=> x = \frac{-(-10) + \sqrt{10^2 - 4 \times (-21) \times 1} }{2 \times 1} \: or \:\frac{-(-10) - \sqrt{10^2 - 4 \times (-21) \times 1} }{2 \times 1}[/tex]

[tex]=> x = \frac{10 + \sqrt{100 + 84} }{2} \: or \:\frac{10 - \sqrt{100 + 84} }{2}[/tex]

[tex]=> x = \frac{10 + \sqrt{184} }{2} \: or \: \frac{10-\sqrt{184} }{2}[/tex]

[tex]=> x = \frac{10 + 2\sqrt{46} }{2} \: or \: \frac{10 - 2\sqrt{46} }{2}[/tex]

[tex]=> x = (5 + \sqrt{46} ) \: or \: (5 - \sqrt{46} )[/tex]

They are wording it tricky, but it is simple. So first if you combine all the balls together there are 7, and 3 blacks ball 3/7.

Answer:

I believe you have the correct answer

Step-by-step explanation:

The probability of drawing a black marble from bag 1 is 2/3.

The probability of drawing a black marble from bag 2 is 1/4.

Since it is consecutive draws, we would multiply the 2 odds.

2/3 * 1/4 = 1/6

Answer:

z = 4.5

Step-by-step explanation:

∠B = ∠B      ∠BAD = 90° - ∠B = ∠C

ΔBAD ~ ΔBCA

AB / z = BD / AB

z = AB * AB / BD = 3*3 / 2 = 4.5

Answer:

6

Step-by-step explanation:

all you have to do is divide 54 by 9 because area is length times width

Answer:

6

Step-by-step explanation:

Area of a rectangle: l x b (Length x Breadth)

Note: Breadth is the same as width

Area = 54

Length = 9

Breadth = 54/9

             = 6

Pleas mark me as brainliest

Answer:

1/216

Step-by-step explanation:

Hi, the probability of rolling it once is 1/6, twice in a row results in multiplying 1/6 by 1/6.

Therefore, three times means using the formula: (1/6)^3

Which gives us the fraction 1/216

The solutions for the given quadratic equation are:4/5 and 1/2.

The quadratic function can represent a quadratic equation in the Standard form: ax²+bx+c=0 where: a, b and c are your respective coefficients. In the quadratic function the coefficient "a" must be different than zero (a≠0) and the degree of the function must be equal to 2.

For solving a quadratic function you should find the discriminant:[tex]D=b^2-4ac[/tex]  . And after that you should apply the discriminant in the formula: [tex]x_{1,\:2}=\frac{-b\pm \sqrt{D}}{2a}[/tex].

For the given question, you have:

a=20

b=-26

c=8

[tex]D=b^2-4ac=\left(-26\right)^2-4\cdot \:20\cdot \:8=676-640=36[/tex]

[tex]x_{1,\:2}=\frac{-b\pm \sqrt{D}}{2a}\\ \\ x_{1,\:2}=\frac{-(-26)\pm \sqrt{36}}{2*20}\\ \\ x_{1,\:2}=\frac{\left26\right\pm \:6}{40}[/tex]

Then,

[tex]x_1=\frac{\left(26\right)+6}{40}=\frac{32}{40}=\frac{4}{5}[/tex]

[tex]x_2=\frac{\left26\right-6}{40}=\frac{20}{40}=\frac{1}{2}[/tex]
