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?
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

The Parkers are getting a new pet. Alan wants a cat, but his sister Jessica wants a dog. Both want a fair method to determine who gets to
choose the new pet.
Alan devised a method using the given spinner
• They will spin the arrow twice and record the outcomes.
. If the product of the outcomes is even, Alan gets to choose the new pet.
• If the product of the outcomes is odd. Jessica gets to choose the new pet.
Answer:
D I think
Step-by-step explanation:
because each choice has a 25% chance to land and there are 2 evens so the chances are a 50% to a 50%
The sampling method isn't fair, it can be resolved by using the sum of the two outcomes rather than he product.
What is sampling?It should be noted that sampling simply means a process whereby a number of observations are taken from the population.
In this case, the sampling method isn't fair, it can be resolved by using the sum of the two outcomes rather than he product.

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.
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

Jason and Adam are using a kit to build their own electronics board for a computer project. They use a scale drawing included in the instructions to help build the board.
Jason will use the scale factor to find the board's actual length and width, then multiply those dimensions to find the board's area.
Adam says he knows another way.
Answer the questions to show how Adam could find the area of the scale drawing, and then use this strategy to find the area of the electronics board.
1. What is the area of the board shown on the scale drawing? Explain how you found the area.
Write your answer in the space below.
2. How can Adam use the scale factor to find the area of the actual electronics board? Remember, he uses a different method than Jason.

The height of a cone is two times its base diameter. What is the volume of the cone in terms of its base radius ?
Step-by-step explanation:
Cone Volume = 1/3 ×( π r² h) h = 2 × diameter = 2 × 2 × r
Cone Volume = 1/3 ×( π r² h) h = 2 × diameter diameter = 2r
= 2 × (2 × r)
= 4r
Cone Volume = 1/3 ×( π r² 4r)
= (4 π r³ / 3)

question is in the image I put!
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
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

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°

Answer:
False, False, True, False
Step-by-step explanation:
1. False. D and F are not parallel as they are intersecting in the diagram.
2. False. Angles 1 and 3 are not corresponding. They are opposite. A pair of corresponding angles would be angles 1 and 5.
3. True. A transversal line is a line that passes through two other lines.
4. False. Angle 6 = 63˚ through corresponding angles. Angle 6 + Angle 7 = 180. 63 + Angle 7 = 180. Angle 7 = 117˚.

$1234 is invested at 5.6% annual interest for 7 years.
a. Simple Interest b. Compound Interest
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.
Use the given information to write the standard form equation of a circle:
a) x²+y²+10x+14y+70=0 translated 1 unit to the right and 2 units down.
Answer:
The formula for the equation of a circle is (x – h) 2 + (y – k) 2 = r 2, where (h, k) represents the coordinates of the center of the circle, and r represents the radius of the circle. If a circle is tangent to the x-axis at (3,0), this means it touches the x-axis at that point.
