Answer: $54\frac{1}{6}$

Step-by-step explanation:

Order of Operations (PEMDAS) states that we need to do the parenthesis first then division and then addition.

50 + (40 - 15) ÷ 6

parenthesis: 50 + 25 ÷ 6

division: 50 + $4\frac{1}{6}$

addition: $54\frac{1}{6}$

After I looked up some quick information, your car loses 15-25% each year. After 5 years, it goes to only 37%. So, a car that would cost 20000 would be valued at around 7k after 5 years. So, in the first 5 years, it lost 14k. Also, a 1999 Corolla goes for 2.5k, and that's nearly 20 years. So, I'm just going to go with, based off these numbers, probably 25-30 years...if it still works by then.
Also, if you get in a heavy accident the next day, making the car unusable, you rip off your friend. The first scenario only applies if the engine works well and no accidents were on the vehicle either.

Describe the graph of the quadratic from the original y = x^2 .

Citrus2011 [14]

Answer:

a. Narrower

b. Shifts left

c. Opens up

d. Shifts up

Step-by-step explanation:

The original quadratic equation is y = x²

The given quadratic equation is y = 5·(x + 4)² + 7

The given quadratic equation is of the form, f(x) = a·(x - h)² + k

a. A quadratic equation is narrower than the standard form when the coefficient is larger than the coefficient in the original equation

The quadratic coefficient is 5 > 1 in the original, therefore, the quadratic equation is narrower

b. Given that the given quadratic equation has positive 'a', and 'b', and h = -4, therefore, the axis of symmetry shifts left

c. The quadratic coefficient is positive, (a = 5), therefore, the quadratic equation opens down

d. The value of 'k' gives the vertical shift, therefore, the given quadratic equation with k = 7, shifts up.

Find the volume of the cone in cubic feet. Use 3.14 for it and round your answer to the nearest tenth.

kenny6666 [7]

$\quad\hookrightarrow\quad \sf {5,790,806.5\:ft^3 }$

<h3>Ⲋⲟⳑⳙⲧⳕⲟⲛ:</h3>

Here, we area provided a cone with:

Radius = 48m
Height = 68 m

We have to find the volume of the cone in feet³, and we are given that 1m = 3.2808ft

<h3>Ⳙ⳽ⲓⲛⳋ ⳨ⲟⲅⲙⳙⳑɑ:</h3>

The volume of a cone is equal to one third of the volume of a cylinder having the same base radius and height ,i.e:

$\quad\longrightarrow\quad \sf { V =\dfrac{1}{3}\pi r^2 h }$

Therefore, Volume:

$\implies\quad \tt {V = \dfrac{1}{3}\pi r^2 h }$

$\implies\quad \tt { V =\dfrac{1}{3}\times 3.14 \times 48^2 \times 68 }$

$\implies\quad \tt { V =\dfrac{1}{\cancel{3}}\times 3.14\times \cancel{2304} \times 68}$

$\implies\quad \tt {V =3.14\times 768\times 68 }$

$\implies\quad \tt {V = 163,983.36}$

$\implies\quad \tt { V = 163,983.36 \times (3.2808)^3 \qquad\quad\bigg[ As, \: 1m = 3.2808ft\bigg]}$

$\implies\quad \tt {V = 163,983.36\times 35.30 }$

$\implies\quad\underline{\pmb{ \tt { V = 5,790,806.5 ft^3}}}$

‎ㅤ‎ㅤ‎ㅤ~Hence, the volume of given cone is 5,790,806.5 ft³.

A coin is tossed and an eight-sided die numbered 1 through 8 is rolled Find the probability of tossing a head and then rolling a

Stells [14]

Answer:

Step-by-step explanation:

Probability of a head is 1/2 of getting heads.

probability of a number greater than 1 is 7/8 on 8 sided die

Total probability = 1/2 * 7/8 = 7/16 = 0.4375
