Select the type of cross section formed when a triangular pyramid is cut parallel to its
base.

The examples of unit rates include miles per hour, blinks per second, calories per serving, and steps per day.

A unit rate is the price for one unit of something. This is written as a ratio with a denominator of one. For instance, if you ran 70 yards in 10 seconds, you averaged 7 yards per second. Both ratios, 70 yards in 10 seconds and 7 yards in 1 second, are rates, but only the latter is a unit rate.

The denominator of a unit rate is always 1. To find the unit rate, divide the denominator by the numerator so that the denominator equals 1.

After simple arithmetic addition, we get the answer as the scale will read 7.7 pounds.

What do you mean by arithmetic addition?

The plus sign (+) is commonly used to indicate addition, one of the four basic mathematical arithmetic operations. Subtraction, multiplication, and division make up the remaining three. The two full numbers are added together to produce the total amount or sum.

Since, there is no difference in units of the given data. Therefore, we can simply do arithmetic addition to get the result which will be shown on the scale.

If the person who had forgot to pay had paid, the shopkeeper would have earned a 20% profit.

It is given that 5 customers bought 10, 15, 20, 25, and 30 toffees from a shop.

Therefore, the total number of toffees bought is

10 + 15 + 20 + 25 + 30 toffees

= 100 toffees.

Let the cost of one toffee be $x.

Hence the cost of 100 toffees is $100x

It is said that we need to consider the customer who had forgotten to pay has actually paid.

Therefore,

the shopkeeper has received money for 100 toffees.

Now, he makes a 20% profit on each toffee

Therefore the selling price of each toffee is-

20% of x  +  x

= 0.2x + x

= $1.2x

Hence for 100 toffees, he receives

$120x

Therefore, the profit made on those toffees is

$120x - $100x

$20x

Therefore profit percentage

= Profit/Cost Price  X  100

= 20x/100x  X 100

= 20%

Hence, he would have made a 20% profit.

Step-by-step explanation:

counting numbers means whole numbers.

these divisible rules mean numbers that are divisible by 4 and by 3 and by 5.

4 = 2×2

so, everything that is divisible by 4 is also divisible by 2.

6 = 2×3

everything that is divisible by 2 and by 3 is also divisible by 6. therefore everything that is divisible by 4 and by 3 is also divisible by 6.

5 is a prime number on its own.

so, we are looking for all numbers that are divisible by

3×4×5 = 60

the smallest common multiple of 2, 3, 4, 5 and 6.

formally we get this by the combination of the longest chains of the prime factors :

2 = 2

3 = 3

4 = 2×2

5 = 5

6 = 2×3

the longest chain of 2 is 2×2.

the longest chain of 3 is 3.

the longest chain of 5 is 5.

so, 2×2×3×5 = 60

therefore, our solution is all numbers divisible by 60.

that means all multiples of 60 between 200 and 500.

what is the lowest number for that ?

3×60 = 180 too low

4×60 = 240 ok

what is the highest number ?

8×60 = 480 ok

9×60 = 540 too high

so, we only have

4×60 = 240

5×60 = 300

6×60 = 360

7×60 = 420

8×60 = 480

we have 5 numbers between 200 and 500 that are divisible by all of 2, 3, 4, 5 and 6.

Manny's total bill is $1699.75 when the dog spent 4 days in veterinary hospital.

According to the question,

We have the following information:

Manny's dog spent 4 days in a veterinary hospital. Manny paid $1585 for the surgery, $16.25 a day for board, and $49.75 for medicine.

Now, for 4 days, we will first find the bill for boarding using multiplication.

Bill for 4 days of boarding = 16.25*4

Bill for 4 days of boarding = $65

Now, in order to find the total bill of 4 days, we will add all the given bills.

Total bill = 1585+65+49.75

Total bill = $1699.75

Hence, Manny's total bill is $1699.75 when the dog spent 4 days in veterinary hospital.

There is currently $62.65 billion in the fund.

Given that;

If the FDIC must use 7.6% of its $67.8 billion insurance reserve to pay for several bankrupt banks,

To get how much money is left in the fund, we need to;

The total insurance fund = $67.8 billion

To cover several failed banks = 7.6% = 0.076

Therefore, the money left = $67.8 * 0.076

                                           = $5.15

So, the final amount left in the fund = $67.8 - $5.15

Claribel needs to pay $875 for 17 months to gym, $25 for one time membership fee and $50 for 17 months.

A set or group of equations that you solve all at once is referred to as a "system" of equations. A linear equation can be represented as Ax + By +C = 0, Where A, B are coefficient and C is the constant. Linear equations (those that graph as straight lines) are easier to understand than non-linear ones.

To find the amount for Claribel, we have to find the monthly fee and one time membership fee for the gym.

Let x be one time membership fee for the gym and y be the monthly fees, so the system of equations will be,

x + 6y = 325

x + 9y = 475

Now, subtracting the above equations, we get

3y = 150

y = 50

Now, putting the value of y in first equation, we get

x + 6(50) = 325

x+300 = 325

x = 25

Now, finding the amount for Claribel,

One time membership fee + 17(Monthly Fee) = Total Amount

Putting the values,

Total Amount = 25 + 17(50)

= 25 + 850

=$ 875

Therefore, Claribel needs to pay $875 for 17 months to gym.

Answer: A

Step-by-step explanation:

The paths that will stay outside or on the boundary of the square-2≤ x≤2, -2≤y ≤2 at each step will be 1698

We'll make advantage of the complementary counting idea. If you enter the square, you must exit by the boundaries and by the designated points because otherwise, you would touch another point in one of the sets of points in the connection (Call it S). Since y=x is symmetric, we simply need to take into account (1,-1), (1,0), and (1,1). We can only investigate one scenario and multiply it by two since (1,1) can cross the barrier in two different ways. We may just multiply (1,0) by two and (1,-1) by two. Therefore, we count the routes from (-4,4) to each of these sites and multiply that number by the total number of routes from the starting position.

Slope is a value that describes the steepness and direction of a line. In variable format, it is commonly represented by the letter m. The slope of a line is also called its gradient or rate of change. The slope formula is the vertical change in y divided by the horizontal change in x, sometimes called rise over run.

The formula to find the slope = (y2-y1)/(x2-x1)
