Answer:

2:5

Step-by-step explanation:

The first step is to write the ratio as it is presented in the question

red marbles : total number of marbles

       50         :             125

then divide both sides by their highest common factor (25)

        2           :              5

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

Hope this helps!! xx

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.

If I invest $2,500 in an account that yields 7.5% interest, how many years will it take to reach a total of $10,000 if it is compounded monthly. A=P(1+(r/n)^nt

You can use guess and check, and first, 2500 * (107.5%)^20 would get us 10619.6277506, and then 19 would guess us an answer that is less than 10000, so 20 months = 1 2/3 years.

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

One pound of grapes costs $1.55. Which equation correctly shows a pair of equivalent ratios that can be used to find the cost of 3.5 pounds of grapes?

Answer:

Given the statement: One pound of grapes costs $1.55.

Let x be be the cost of 3.5 pounds of grapes.

Equivalent ratios states that the  two ratios that express the same relationship between numbers.

Therefore, by equivalent ratio:

\frac{1 pound}{cost of 1 grapes} =\frac{3.5 pound}{cost of 3.5 grapes}

then, we have;

\frac{1}{1.55}=\frac{3.5}{x}

Cross multiply the above equation; we hve

x = 1.55 \times 3.5

x = 5.425

therefore, the cost of 3.5 pounds of grapes is, $5.425

QUESTION POSTED AT 22/02/2020 - 06:52 PM

Nuts.com sells raw almonds for $10 per pound and roasted pistachios for $12 per pound. Christopher spends $70, before taxes and shipping, to purchase 6.3 total pounds of nuts

Answer:

Christopher bought 3.5 pounds of roasted pistachios and 2.8 pounds of raw almonds.

Step-by-step explanation:

From the information given, we can write the following equations:

A+P= 6.3 ①

10A+12P= 70 ②

To resolve them, we have to isolate one of the variables in the first equation and then replace that in the second equation:

A=6.3-P ③

10(6.3-P)+12P=70

63-10P+12P= 70

2P= 70-63

P= 7/2=3.5

Now, that we have found the quantity of roasted pistachios, we can replace that in equation number 3 to find the quantity of raw almonds:

A= 6.3-3.5= 2.8
