The sum of two numbers is 44 .one number is 3 times as large as the other. what are the numbers?

You can set it up like this:

x + 3x = 44

Combine like terms:

4x = 44

Divide both sides by 4:

x = 11. 

So, one number is 11, and the other number (the larger one) is 33

QUESTION POSTED AT 22/02/2020 - 11:33 PM

The population of a city is excpted to increase by 7.5% next year. If p represents the current population, which expression represents the excepted population next year? A)1.75p B)1.075p C)p+0.075 D)1+0.075 can someone please help me, anyone please

"excepted?"  I think you meant "expected."

In this problem you need to convert that "7.5%" into a decimal fraction:  0.075.
The increase in population will be 0.075 times p, the current population.  You then add that to p, the current population.

But it's easier and faster to multiply p by 1.075.  Thus, 1.075p is the correct answer.

Matthew is training to participate in a half marathon. The table below shows the number of miles he runs in weeks 1 and 2. Week Number of Miles Run 1 12.5 2 13.5 Each week, Matthew increases the number of miles he runs in the previous week by the same percent. How many miles does Matthew run in week 3? Do not round your answer

Answer:

14.58 miles.

Step-by-step explanation:

Matthew is training to participate in a half marathon.

The distance covered by Matthew on the first day is 12.5 miles.

The distance covered by Matthew on the second day is 13.5 miles.

The distance increased on the second day is, 13.5-12.5=1 mile.

The percentage will be,

=\dfrac{1}{12.5}\times 100\%

=0.08\times 100\%

=8\%

Hence, each day he runs 8% more. So the distance covered by him on day 3 will be,

=13.5+\left(13.5\times \dfrac{8}{100}\right)

=13.5+1.08

=14.58 miles

As a fundraiser, the band is selling cookies. The cost to make each cookie can be written as c(x) = 0.25x + 0.5 and the functions that represents the amount they sell the cookie for can be written as s(x) = 2x. What function represents the profit, P(x), for each function?

The profit it's the money that you make minus the money that you sell. So
P(x) = s(x) - c(x)
P(x) = (2x) - (0.25x + 0.5)
P(x) = 2x - 0.25x - 0.5
P(x) = 1.75x - 0.5

An earring design is shaped like a triangular pyramid. All the faces are equilateral triangles with side lengths of 14 millimeters. The slant height is 12.1 millimeters. What is the surface area of the earring (pls explain how u got the answer)

In the earring design described above, there are 4 equilateral triangles. The surface area is calculated by solving for the area of a single triangle and multiplying the answer by 4. The area of an equilateral triangle is calculated by the equation,
                                   A = ((√3)/4)s²
Substituting 14 to s and multiplying the answer by 4
                                 SA = √3 x (14 mm)² = 339.48 mm²
Thus, the surface area of the earring is approximately 339.48 mm².

QUESTION POSTED AT 22/02/2020 - 07:08 PM

Which system of equations below has no solution? A. y = 4x + 5 and y = 4x – 5 B. y = 4x + 5 and 2y = 8x + 10 C. y = 4x + 5 and y = 1/4 + 5 D. y = 4x + 5 and y = 8x + 10

Answer:

A.  y = 4x + 5 and y = 4x – 5

Step-by-step explanation:

If the system of equations have the same slope and different y-intercept, then it will have no solution.

From the given options, let's find the slope and y-intercept.

A. y = 4x  + 5 and y = 4x - 5

Slope = 4 and y-intercepts are 5 and -5

Here we have the same slope and different y-intercepts. So, this is systems of equations have no solution.

B. y = 4x + 5 and 2y = 8x + 10 => y = 4x + 5

Both are the same equations.

This system  has an infinite number of solutions.

The answer is A)  y = 4x + 5 and y = 4x – 5
