Answer:
The correct options are C and D
Important information:
Meg laid 15 tiles in 50 minutes.
Jessica worked for 85 minutes at a faster rate per tile than Meg.
Step-by-step explanation:
The rate per tile of Meg is:
Rate = time/no. of tiles
Rate = 50/15
Rate = 3.333333...etc
Calculate the rates per tile for each option.
85/20 = 4.25
85/24 = 3.54167...
85/28 = 3.0357
3/1 = 3
4/1 = 4
From the above calculation is clear that the time spent per tile is less than Meg's rate in options C and D.
Therefore, the correct options are C and D.

∠A and ∠B are complementary angles. If m∠A = (7x + 25)∘ and m∠B = ( x + 9)∘ , then find the measure of ∠A
Answer:
x = 7
Angle A = 74
Angle B = 16
Proofs attached to answer
Step-by-step explanation:
Proofs attached to answer
Answer:
<A = 74
Step-by-step explanation:
We know that being complementary angles refer to..Sum of two angles = 90°.
So,
<A + <B = 90
i.e. (7x + 25) + (x+9) = 90
or, 8x + 34 = 90
or, 8x = 90-34
or, x = 56/8
or, x = 7
Again,
<A = 7x + 25
or, <A = 7*7 + 25
or, <A = 74
•°• <A = 74..... Is your ANS

Answer: the golden one is the correct one
Step-by-step explanation:
in order for Michael to know how many more points he needs to equal with Janet he need to add how many points she has (200 + 400) then subject how much he has (250) and get p
(200 + 400) - 250 = p
you need to do 200 + 400 first, hence the parentheses.
Two same-sized triangular prisms are attached to a rectangular prism as shown below. If a = 20 cm, b = cm, c = cm, d = 4 cm, and e = 8 cm, what is the surface area of the figure?
Answer:
Step-by-step explanation:
Answer: a) 1,208 square centimeters
The surface area would be the sum of the different areas separated in the figure.
The area of the front and back faces of the rectangular prism:
The area of the top and the base of the rectangular prism:
The area of the front and back faces of both triangular prisms:
The area of the side faces of both triangular prisms:
The area of the bases of both triangular prisms:
Finally, the surface area of the whole figure:

A car travels 180 km in 3 h. At this rate, how far will the car travel in 7 h?
Answer: 420km
Step-by-step explanation:
So let us start by stating the obvious, a car has travelled 180 km in 3 hrs.
So:
3h = 180km
now double both sides:
6h = 360km
now let us find 1h by dividing 3h = 180km by 3:
1h = 60km
now we can add 6h = 360km and 1h = 60km which gives us:
7h = 420 km

pls last question of aleks assigment pls top g
The charity gala costs a flat fee of $4, plus an additional $11 per attendee. Is the total cost directly proportional to the number of attendees?
No, the total cost is not directly proportional to the number of attendees because there is a flat fee of $4 that does not depend on the number of attendees. If the total cost were directly proportional to the number of attendees, then the cost per attendee would be constant regardless of the number of attendees, but in this case, the cost per attendee decreases as the number of attendees increases due to the fixed flat fee.

D) Multiply one dimension of the prism by two and keep the other dimensions the same.
Step-by-step explanation:
When multiplying a volume of a rectangular prism regularly it would be B×h or l×w×h would be 10×2×5 = [tex]100cm^{3}[/tex].
However if doubled, or multiplied by 2 our new result would be [tex]200cm^{3}[/tex]. The way to find this is by multiplying only one dimension, or side, as the rest will remain the same.
There are 3 possible equations you could do with the given information.
(10×2)×2×5, 10×(2×2)×5, or 10×2×(5×2).
All of these, individually multiply up to 200 which is also double the amount of the regular volume.

A coin (H: heads; T: tails) is flipped and a number cube (1, 2, 3, 4, 5, 6) is rolled. What is the sample space for this experiment?
A. T1, T2, T3, T4, T5, T6
B. H, T, 1, 2, 3, 4, 5, 6
C. H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6
D. H1, H2, H3, H4, H5, H6
Explanation:
Start with the set {1, 2, 3, 4, 5, 6}
Stick "H" in front of each item to get {H1, H2, H3, H4, H5, H6} which represents half of the sample space. Something like H2 means "coin flipped heads and the number cube rolled a 2".
The other half of the sample space involves replacing each H with T. Which explains how we get T1, T2, T3, T4, T5, T6
Overall, the sample space is:
{H1, H2, H3, H4, H5, H6, T1, T2, T3, T4, T5, T6}
It might help to organize things into a table like this:
[tex]\begin{array}{|c|c|c|c|c|c|c|} \cline{1-7}& 1 & 2 & 3 & 4 & 5 & 6\\\cline{1-7}H & H1 & H2 & H3 & H4 & H5 & H6\\\cline{1-7}T & T1 & T2 & T3 & T4 & T5 & T6\\\cline{1-7}\end{array}[/tex]
Or it could be written like this:
[tex]\begin{array}{|c|c|c|} \cline{1-3}& H & T\\\cline{1-3}1 & H1 & T1\\\cline{1-3}2 & H2 & T2\\\cline{1-3}3 & H3 & T3\\\cline{1-3}4 & H4 & T4\\\cline{1-3}5 & H5 & T5\\\cline{1-3}6 & H6 & T6\\\cline{1-3}\end{array}[/tex]
Either table demonstrates how there are 6*2 = 12 items in the sample space.

Calculate the probability of the event.
Answer:
well, the other colors on the wheel are less because people prefered green
Step-by-step explanation:
Step-by-step explanation:
So its hard to calculate actual probability without any numbers. But seeing that there are a total of 6 colors on the wheel, and that green is the largest (by a lot since its almost half the wheel) the probability of landing green is very high.
And that's all you can say really...black will be lowest, and yellow seems to be the next highest. In comparison to green though, probability of the other colors will be low.

QUESTION 1
The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters.
What is a square?
A square is a geometrical figure in which we have four sides each side must be equal and the angle between two adjacent sides must be 90 degrees.
Area of square = Side²
The perimeter of the square = 4 × side
As per the given square perimeter.
4(x + 3.3) = 28
x + 3.3 = 7
x = 3.7 meters.
Hence"The value of the x for the given square such that its perimeter is 28 meters will be 3.7 meters".

The scale used for a model of an Orca whale is 1 in: 4
ft. If the model of the Orca is 5 inches long, how long is
the actual whale?
Answer: this is unrealistic but the way the question is written it makes me believe that the orca is 20 ft but that’s defiantly wrong so it’s either a really small whale or you add a zero at the end and are you sure you didn’t leave out any details because the question is written in a weird way

If the cost of goods sold is 65% of sales and sales are $720,000, what is the cost of goods sold?
To find the cost of goods sold, we need to multiply the sales by the percentage of the cost of goods sold, expressed as a decimal:
Cost of goods sold = 0.65 × $720,000
Cost of goods sold = $468,000
Therefore, the cost of goods sold is $468,000.
At a cost of $110 each, how many calculators can be purchased with a budget of $8,800?
To find the number of calculators that can be purchased, we need to divide the budget by the cost per calculator:
Number of calculators = $8,800 ÷ $110
Number of calculators = 80
Therefore, 80 calculators can be purchased with a budget of $8,800.
a is the cost of adult tickets.
s is the cost of students tickets.
The cost of each type of ticket is $10.
The solution of an equation differ from the solution of a linear system of equations because because it only satisfies a single equation.
How to determine the number of each type of tickets sold?In order to write a system of linear equations to describe this situation, we would assign variables to the cost of adult tickets sold and cost of student tickets sold, and then translate the word problem into an algebraic equation as follows:
Let the variable a represent the cost of adult tickets sold.Let the variable s represent the cost of students tickets sold.The total amount of money that Ashley charged the first person is represented by this linear equation:
2a + 2s = 40
For the second person, we have:
a + 3s = 40
By solving the system of linear equations simultaneously, we have:
2(40 - 3s) + 2s = 40
80 - 6s + 2s = 40
4s = 40
s = $10.
For the value of adult ticket (a), we have:
a = 40 - 3s = 40 - 3(10) = $10.
For the third person, we have:
Cost = 3a + 5s
Cost = 3(10) + 5(10) = $80.
