Answer:

360

Step-by-step explanation:

the picture is 2 triangles and all of the angles of a triangle add up to 180 degrees but then you have to multiply it by the number triangles so 180*2=360

What are the solutions of the equation<br> x^2 - 30 = x?

sashaice [31]

Answer:

x = 6 , − 5

Step-by-step explanation:

Move x to the left side of the equation by subtracting it from both sides. x^ 2 − 30 − x = 0

x2-30-x=0

Use the quadratic formula to find the solutions. − b ± √ b 2 − 4 ( a c )/ 2 a

-b±b2-4(ac)/2a

Substitute the values

a = 1 , b = − 1 , and c = − 30

into the quadratic formula and solve for x

x . 1 ± √ ( − 1 ) 2 − 4 ⋅ ( 1 ⋅ − 30 )/ 2 ⋅ 1

Simplify.

x = 1 ± 11/ 2

The final answer is the combination of both solutions.

x = 6 , − 5

According to postal regulations, a carton is classified as "oversized" if the sum of its height and girth (the perimeter of its

sergij07 [2.7K]

Answer:

Square base dimension = 15 inches

Maximum volume = 7200 inches^3

Step-by-step explanation:

V = x^2y ..... eq 1

Let the square base be x and the height y

Oversize formular is given by

Y + 4x = 92

Y= 92 - 4x .....eq 2

Put eq 2 into eq 1

V = x^2 ( 92 - 4x^3)

V= 92x^2 - 4x^3

Using derivatives

V= 184x - 12x^2

V'= 0 = 184x - 12x^2

X(184 -12x)

X=0

X = 184/12 = 15.33 approximately 15 inches

Maximum Volume = V= 92(15)^2 -5(15)^3

V= 92(225) - 4(3475)

V= 20700 - 13500

V= 7200 inches^3

alisson separates her 23 stickers into 4 equal piles.how many stickers does she have left over? A27 B 19 C 5 D 3

klemol [59]

We need to find the remainder- the sticker left over

Divide 23 stickers into 4 piles = 23/4= 5 stickers per pile and 3 stickers left over

D. She would have 3 stickers left over

An = a1 + (n - 1)d

yarga [219]

Answer:

The car will travel 1980 meters in 15 minutes.

Hence, option 'D' is true.

Step-by-step explanation:

Given that a car travels 300 meters in the first minute, so

a₁ = 300

Each minute after, the car travels 120 meters. , so the sequence becomes

a₁, a₂, a₃, a₄, a₅, ...

300, 420, 540, 660, 780, ...

An arithmetic sequence has a constant difference 'd' and is defined by

$a_n=a_1+\left(n-1\right)d$

computing the differences of all the adjacent terms

$20-300=120,\:\quad \:540-420=120,\:\quad \:660-540=120,\:\quad \:780-660=120$

The difference between all the adjacent terms is the same and equal to $d=120$

now, we have

a₁ = 300

d = 120

so substituting a₁ = 300 and d = 120 in the nth term of the sequence

$a_n=a_1+\left(n-1\right)d$

$a_n=120\left(n-1\right)+300$

$a_n=120n+180$

Thus, the nth term of the sequence is:

$a_n=120n+180$

<u>Determining the distance the car travels in 15 minutes</u>

As we have already determined the nth term of the sequence such as

$a_n=120n+180$

now substituting n = 15

$a_{15}=120\left(15\right)+180$

$a_{15}=1800+180$

$a_{15}=1980$

Therefore, the car will travel 1980 meters in 15 minutes.

Hence, option 'D' is true.
