The pupils in my class work very quickly. Jasleen answers four questions every
30
seconds and Ella answers five questions every
40
seconds.

Last week, Jasleen took exactly
1
hour to answer a large set of questions.

How many minutes more than Jasleen did Ella take to answer the same set of questions?

Answers

Answer:

4 mins more would be  taken by Ellina

Step-by-step explanation:

Given that

Jasleen answers 4 questions every 30 seconds

And, Ella answers 5 questions every 40 seconds

And, last week Jasleen took exactly 1 hour for answering a large set of questions

We need to find out the number of more minutes taken by Ella

As Jasleen answers four questions every 30 seconds

So, Jasleen answers  8 questions for every 1 minutes

Now

Jasleen answers time taken

=  60 × 8

= 480 questions for every 60 minutes  or 1hr

On the other hand

Ella answers five questions every 40 seconds.

So, 1 questions in 8 sec

Now for 480 Questions , it would take

= 480 × 8 secs

= 480  × 8  ÷ 60  min

= 8 × 8

= 64 mins

Hence 4 mins more would be  taken by Ellina

Answer:

20°

Step-by-step explanation:

60 = (x + 40) (opposite angles are equal)]

x = 60 - 40 = 20°

Answer:

=> x = 20°

Step-by-step explanation:

here's your solution

==> both are vertical angle ,so both are equal

==> 60° = x + 40°

==> - x = -60° + 40°

==> - x = - 20°

==> x = 20°

Answers

Answer:

55

Step-by-step explanation:

The equation of the Ferris wheel circle is [tex](x-0)^{2} +(y - 104.375)^{2} = (100)^{2}[/tex]

What is Ferris wheel?

A Ferris wheel is an amusement park ride consisting of a large vertical wheel with places for people to sit or stand spaced evenly around the outer circumference.

What is the standard equation of the circle?

The standard equation of the circle is

[tex](x-h)^{2} +(y-k)^{2}= r^{2}[/tex]

Where,

(h, k) is the center of the circle

and, r is the radius of the circle

According to the given question.

The diameter of the Ferris wheel is 200 feet

[tex]\implies radius\ of \ the\ Ferris\ wheel = \frac{200}{2} = 100feet[/tex]

Height of the platform = 7 × 7.5 = 52.5 inches = 4.375 feet

Therefore,

[tex]k = 4.375+100 = 104.375feet[/tex]

and

[tex]h = 0[/tex]

Therefore, the equation of the Ferris wheel circle is

[tex](x-0)^{2} +(y - 104.375)^{2} = (100)^{2}[/tex]

i think so,

(5x-54)⁰=(3x+16)⁰

5x-3x=16+54

2x=70

x=35⁰

3x+16=3×35+16=121

5x-54=5×35-54=121

hope it helps

have a nice day

Answer:

x = 35

The angles measure 121°

Step-by-step explanation:

Alternate interior angles are congruent. So,

3x + 16 = 5x - 54

16 = 2x - 54

70 = 2x

x = 35

Now, to find the angle measures, just plug in the value for x.

3(35) + 16 = 121°

5(35) - 54 = 121°

25 POINTS AND BRAINLIEST 6. Consider the following figure.
Part A: Determine the PERIMETER of the figure above.
Part B: Determine the AREA of the figure above.

Answers

Answer: The perimeter is 95 + 15 sqrt 3, and the area is 600 + 35 sqrt 3 / 2

Step-by-step explanation:

We can draw an imaginary line to form a 30 60 90 triangle. The ratio of side lengths in this special triangle is 1 sqrt 3 2. We are given that the side length opposite to 60 degrees is 15. 15 divided by sqrt 3 is equal to 5 sqrt 3. Now, to find the diagonal we can do 5 sqrt 3 * 2 = 10 sqrt 3. So now, we can find the perimeter. The perimeter is equal to 15 + 40 + 40 + 5 sqrt 3 + 10 sqrt 3 = 95 + 15 sqrt 3. Now, we can find the area. The area can be split into the rectangle's area and the triangle's area. The rectangle's area is 15 * 40 = 600. The triangle's area is 15 * 5 sqrt 3 / 2 = 35 sqrt 3 / 2. The total area is 600 + 35 sqrt 3 / 2.

Answer:

Perimeter: 95+15*sqrt(3)=120.98

Area: ([45*sqrt(5)]/2) + 600=605.3

A student takes the same street from his home to the university every day. There are 3 streetlights along the way, and he has noticed the following Markov dependence. If he sees a green light at an intersection, then 77% of time the next light is also green. However, if he sees a red light, then 77% of time the next light is also red. (Assume the chance of him seeing a yellow light is zero.) If the first light is green, what is the probability that the third light is red

Answers

Answer:

0.3542 = 35.42% probability that the third light is red

Step-by-step explanation:

For each light:

If it is green, 77% probability that the next is green.

If it is red, 77% probability that the next is red.

If the first light is green, what is the probability that the third light is red?

These following outcomes are desired, for the second and third lights:

G - R(0.77, then 1 - 0.77 = 0.23 probability)

R - R(0.23, then 0.77 probability).

So the desired probability is:

[tex]p = 0.77*0.23 + 0.23*0.77 = 0.3542[/tex]

0.3542 = 35.42% probability that the third light is red

Solve the following equation for x. x^2 - 36 = 0

B. x=-1 x=36
C. x=-6 x=6
D. x=-18 x=18

Answer:

The answer is C.x=6,x=-6

Step-by-step explanation:

Greetings!

x²-36=0x²-36+36=0+36.. add 36 both sidesx²=36... simplify

An assumption

"In general, all equations of the form x² = a, where a is a positive number, will always give two solutions, namely x = - √a or x = √a."

$1234 is invested at 5.6% annual interest for 7 years.
a. Simple Interest b. Compound Interest

Answers

Answer:

A)  $1,717.73.

B)  $1,807.02.

Step-by-step explanation:

Given that $ 1234 is invested at 5.6% annual interest for 7 years, to determine the final amount applying a simple interest and a compound interest, the following calculations must be performed:

A)

1234 + ((1234 x 0.056) x 7) = X

1234 + (69.104 x 7) = X

1234 + 483.728 = X

1717.728 = X

Therefore, applying a simple interest of 5.6% per year, in 7 years the amount invested would be $ 1,717.73.

B)

1234 x (1 + 0.056) ^ 7 = X

1234 x 1.056 ^ 7 = X

1234 x 1.464 = X

1,807.02 = X

Therefore, applying compound interest, the sum would become $ 1,807.02.
