1 2/5 hours to download, and you downloaded for 5 1/4 hours, how many movies did you download?

Answer:

87

Step-by-step explanation:

In math, the mean is the middle number of a sequence.

9514 1404 393

Answer:

  see attached

Step-by-step explanation:

Translation right 6 units adds 6 to every x-coordinate. Rotation 90° CW is the transformation (x, y) ⇒ (y, -x). The sequence of transformations gives ...

  (x, y) ⇒ (y, -x-6)

Then the coordinates of the transformed figure are ...

  P(-3, 7) ⇒ P'(7, -3)

  Q(4, 12) ⇒ Q'(12, -10)

  R(4, -2) ⇒ R'(-2, -10)

  S(-3, -7) ⇒ S'(-7, -3)

Answer:

D

Step-by-step explanation:

The interval at which the graph of y = cos x is strictly increasing is

π < x < 2π.

Option D is the correct answer.

There are three commonly used trigonometric identities.

Sin x = 1/ cosec x

Cos x = 1/ sec x

Tan x = 1/ cot x or sin x / cos x

Cot x = cos x / sin x

We have,

y = cos x

Cos π = cos (π/2 + π/2) = Sin π/2 = 1

Cos 2π = Cos (π + π) = - Cos π = - Cos (π/2 + π/2) = - Sin π/2 = -1

We see that,

y = Cos x is strictly increasing from -1 to 1.

Thus,

y = cos x is strictly increasing from π < x  < 2π.

Answer: =80/11

Step-by-step explanation:x=80-10x

We move all terms to the left:

x-(80-10x)=0

We add all the numbers together, and all the variables

x-(-10x+80)=0

We get rid of parentheses

x+10x-80=0

We add all the numbers together, and all the variables

11x-80=0

We move all terms containing x to the left, all other terms to the right

11x=80

x=80/11

x=7+3/11

Answer:

r=−1/5

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

5(r−10)=−51

(5)(r)+(5)(−10)=−51(Distribute)

5r+−50=−51

5r−50=−51

Step 2: Add 50 to both sides.

5r−50+50=−51+50

5r=−1Step 3: Divide both sides by 5.

5r/5=−1/5

r=−1/5

Answer:

Step-by-step explanation:

5(r - 10) = -51

5r - 50 = -51

5r = -51 + 50

5r = -1

r = - ¹/₅ or 0.2

Answer: Find the the height and length of the triangle. I'm not sure what it would be but then use a1  + a2 to find the area

Answer:

Formula of triangle: A = 1/2 x b x h

Step-by-step explanation:

Solve the base of the triangle by solving the distance between points (-2,0) and (f, -5) in units, and then do the same for height: find distance between points (-2, 6) and (-2, 0). Once you find the distance, input value of base and height into the formula and solve to get the area!

Step-by-step explanation:

Answer:

Angle FNT = 120 Degrees because the angles labeled 7a+50 and 14a-20 are the same because the lines are parralel so you can set them equal to eachother 7a+50=14a-20 and find that a=10 After this you plug 10 into either 7a+50 and 14a-20 to get 120. You know Angle FNT is 120 degrees because it is directly across from 7a+50 which means they are the same. Then the measure of Angle KTU is 60 because Angle KTN + Angle KTU needs to add up to 180.

Ratio of number of boys to girls to total number of children= 2:3:5

Step-by-step explanation:

42 boys and 63 girls took part in an art competition

The ratio of the number of boys to the number of girls can be calculated as follows

= 42/63

= 2:3

The ratio of the number of boys to girls to total number of children can be calculated as follows

= 42/63/105

Food booth= (75+10d)17

Game booth= (95+4d)21

Step-by-step explanation:

GAME BOOTH

$95 initial fee plus $4 per d amount of days

f(x)=95+4d

Multiply the expression by 21 because you have 21 game booths

FOOD BOOTH

$75 initial fee plus $10 per d amount of days

f(z)=75+10d)

multiply this expression by 17 because their are 17 food booths

Answer:

324 and 144

Step-by-step explanation:

We require

a₁, a₂, a₃, a₄

where a₂ and a₃ are the required geometric means

The n th term of a geometric sequence is

[tex]a_{n}[/tex] = a₁[tex](r)^{n-1}[/tex]

where a₁ is the first term and r the common ratio

Here a₁ = 729 and a₄ = 64, thus

729(r³) = 64 ( divide both sides by 729 )

r³ = [tex]\frac{64}{729}[/tex] ( take the cube root of both sides )

r = [tex]\sqrt[3]{\frac{64}{729} }[/tex] = [tex]\frac{4}{9}[/tex] , then

a₂ = 729 × [tex]\frac{4}{9}[/tex] = 81 × 4 = 324

a₃ = 324 × [tex]\frac{4}{9}[/tex] = 36 × 4 = 144

Thus

729, 324, 144, 64
