Answer:

15 min

Step-by-step explanation:

6 episodes in 1.5 hrs.

1 episode in 1.5/6 hr.

i.e. 1.5*60/6 min

=15 min

Answer:

Step-by-step explanation:

option B

Complementary angles add up to 90°

m∠A + m∠B = 90

30 + 2x + 10 = 90

       2x + 40 = 90

To find the value of x, we have to isolate x. To isolate x, first we have subtract 40 from both sides.

2x = 90 -40

2x = 50

Now, divide both sides by 2

x = 50/2

x = 25°

∠B = 2x + 10

      = 2*25 + 10

    = 50 + 10

∠B = 60°

Step-by-step explanation:

Hey there!

3x + (4x+5)° = 180° {sum of co-interior angle 180°}

7x= 180°-5°

7x= 175°

[tex]x = \frac{175}{7} [/tex]

Therefore, X= 25°.

The answer to the question is -4/5

Refer to picture below:

Answer/Step-by-step explanation:

Perimeter of a right triangle : 3 units , 5 units, 4 units

Perimeter = 3 + 4 + 5 = 12

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Surfaces of a three-dimensional figure: 5ft, 7 ft, 3 ft

Surfaces area: 2(7*3)+2(7*5)+2(3*5)

= 142 square feet

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Volume of a three-dimensional figure: 4m , 10 m , 3 m

Volume = 10 * 4 * 3 = 120 cubic meter

~Lenvy~

Answer:

Step-by-step explanation:

Perimeter of a triangle = sum of 3 sides

= 3 + 4 + 5

= 12 units

Surfaces of a three-dimensional figure = sum of 3 pairs of surfaces

= 5*7*2 + 7*3*2 + 3*5*2

= 70 + 42 + 30

= 142 square fts

Volume of a three-dimensional figure = length*width*height

= 4*10*3

= 120 m^3

Answer:

452.16 m²

Step-by-step explanation:

Given :-

Radius = 12 m

To Find :-

Area

Formula Required :-

Area (circle) = πr²

Solving :-

Area = 3.14 x 12 x 12

= 3.14 x 144

= 452.16 m²

Solution :-

452.16 m²

Answer:

144

Step-by-step explanation:

A=πr^2

Where:

A

is the Area of the Circle: what we are solving for in this problem.

r

is the Radius of the Circle: 12 meters for this problem

Substituting and calculating

A

gives:

A=π(12)^2m^2

A=π144m^2

A= 144m^2

This circle would have an area of 144 square meters.

Answer:

a store is charged $5.50 each for calculators and a delivery of $25 for the order. If stores sells the calculators for $8 each, how many calculators must be sold to produce a profit of at least $80?

Step-by-step explanation:

Cost minus the charge which is 8 dollars minus 5.50 is the difference in which you divide 80 by it. 8-5.50= 2.5.     80 divided by 25 = 32. Hope this is the answer you're looking for.

  x = -8

Step-by-step explanation:

The sum of arcs of a semicircle is 180°. That means the arc whose measure is -11x+12 has a measure of 180° -80° = 100°.

  -11x +12 = 100

  -11x = 88 . . . . . . subtract 12

  x = -8 . . . . . . . divide by -11

in order to calculate the points E & F it is needed to solve the equations y=2*0+5 and 2x+5=0;

in order to calculate the vertex G it is needed to find x-coordinate:

x=(-4)/(2*1)=-2 and to substitute x=-2 into y=x²+4x-1 (y=-5).

Answer:

They should leave Carlo's house by 4:20 PM

Step-by-step explanation:

The movie starts at 8:10 pm, they want to arrive 20 minutes before the movie starts

20 minutes before 8:10 pm = 7:50 pm.

Hence, they should arrive by 7:50 pm

Duration of their activities before the movie is calculated as:

They will bowl for one hour and dinner will take 1 hour and 15 minutes. Travel time is 20 minutes to the bowling alley, 45 minutes ta the restaurant, and ten minutes to the theater.

: 1 hour + 1 hour 15 minutes + 20 minutes + 45 minutes + 10 minutes

= 2 hour 15 minutes + 75 minutes

= 2 hour 15 minutes +1 hour 15 minutes

= 3 hours 30 minutes in total.

The time they are meant to leave is calculated as:

7:50 pm - 3 hours 30 minutes

= 4:20pm

I'm absolutely certain that the answer is 2. (0,-4), (5,3), (-4,3), (3,2) because in a function, x does not repeat

I hope this helps, love!

Step-by-step explanation:

The volume of the vase obtained by revolving the curve y=2+sinx from x=0 to x=5 about the x-axis is 80.115 unit³

Volume is the amount of space occupied by a three dimensional shape or object.

The volume V is given by:

[tex]V=\pi \int\limits^0_5 {(R^2-r^2)} \, dx \\\\R = 2+sinx;r=0, hence:\\\\V=\pi \int\limits^0_5 {(2+sinx)^2} \, dx\\\\V=80.115\ unit^3[/tex]

Answer:

56.6 ft

Step-by-step explanation:

→ Perimeter = All sides added together

5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6

Answer:

56.6

Step-by-step explanation:

Perimeter is just adding all the outer value of an shape

So we add all the answers

5.2 + 5.2 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 + 7.7 = 56.6

but there is easier way

5.2 x 2 = 10.4

7.7 x 6 = 46.2

10.4 + 46.2 = 56.6

at the end don't forget to add "ft"

Answer = 56.6 ft

Given

Functions f(x) and g(x) = k⋅f(x)

Answer:

third one

Step-by-step explanation:

The total amount accrued, principal plus interest, with compound interest on a principal of $4,000.00 at a rate of 2.48% per year compounded 4 times per year over 1 years is $4,100.13.

Given Data

A = P + I where

P (principal) = $4,000.00

I (interest) = $100.13

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 2.48/100

r = 0.0248 rate per year,

Then solve the equation for A

A = P(1 + r/n)^nt

A = 4,000.00(1 + 0.0248/4)^(4)(1)

A = 4,000.00(1 + 0.0062)^(4)

A = $4,100.13
