How many cups will I need for 30 biscuits if there’s 2 cups for every 8 biscuits

Answers

divide 30/8 = 3.75

3.75 *2 = 7.5 cups

If there's 2 cups for every 8 biscuits (not try to be mean, but I really really hate biscuit) there will be 7.5 cups. First, you take 8 and divide it by 2 to find out how many biscuits that 1 cup needs, so 4 biscuits per cup. Last, all you have to do left is take 30 and divide it by 4, which will gives you 7.5. So, for 30 biscuits, you will need 7.5 cups, even though I don't know what cup is it (flour, sugar, salt, water,...).

in geotown, there are 210 own a tablet. This is at least 4/5 of all teenagers that live in geotown. What is the maximum number of teenagers who live geo town

Answers

210 = 4/5 (This means that 4 out of five people (210 people) are a teenager)

Then you divide 210 by the numerator to get 1/5 people:
210 / 4 = 52.5

Then you can multiply the 1/5 people (52.5) by 5 to get 5/5:
52.5 * 5 =  262.5 (rounded to 262)

Thus the maximum amount of teenagers in Geotown is 262.

Hope this helps! :)
Final answer:

The maximum number of teenagers who live in Geotown can be found by solving an equation using the given information that 210 teenagers own a tablet, which is at least 4/5 of all teenagers in Geotown.

Explanation:

We are given that 210 teenagers own a tablet, and this number is at least 4/5 of all teenagers in Geotown. Let's represent the total number of teenagers in Geotown as 'x'. According to the given information, 4/5 of x is equal to 210. We can set up the equation (4/5)x = 210 and solve for x.

To solve for x, we can multiply both sides of the equation by the reciprocal of 4/5, which is 5/4. This gives us x = (5/4) × 210 = 262.5. However, since the number of teenagers must be a whole number, we round down to the nearest whole number and conclude that the maximum number of teenagers who live in Geotown is 262.

Solve 14n+q=rt-4n for n

Answers

Hey there!

In order to solve this, all you need to do is cancel out terms until you have n on one side of the equal sign and everything else on the other side. 

14n + q = rt – 4n (add 4n to both sides to combine 4n and 14n)
18n + q = rt (subtract q from both sides)
18n = rt – q (divide both sides by 18)
n = (rt – q) ÷ 18

Hope this helped you out! :-)

The solution for n is [tex]\( n = \frac{{q - rt}}{{10}} \)[/tex].

To solve for n in the equation -14n + q = rt - 4n, we need to isolate n on one side of the equation.

First, let's gather all terms involving n on one side. Adding 4n to both sides of the equation, we get:

-14n + 4n + q = rt

Simplifying the left side, we have:

-14 + 4)n + q = rt

-10n + q = rt

Next, let's isolate n by moving the term q to the other side. Subtracting q from both sides, we have:

-10n = rt - q

Finally, to solve for n, divide both sides by -10:

[tex]\[ n = \frac{{rt - q}}{{-10}} \][/tex]

So, the solution for n is [tex]n = \frac{{q - rt}}{{10}} \)[/tex].

A warehouse floor has a perimeter of 6,615 feet. What is the perimeter of the floor in yards ? oh and please tell me how you got the answer

Answers

Since there are 3 feet in 1 yard you need to divide 6,615 divided by 3 which equals 2205 yards.
1 Yard = 3 feet
or 3 feet = 1 yard

to convert 6615 feet into yard, you have to divide it by 3.

6615 feet = 6615/3 yard = 2205 yard.

Your answer is 2205 yards.

Alright, to get 1% of his unpaid balance, we can make 1% = 0.01 by moving the decimal place 2 places over. Multiplying 0.01 by 2365 gets 1% of your unpaid balance=23.65. Since we have to add 15 as a base value, we have

A relay race is 1/10 kilometer long. Four athletes will run an equal distance to complete the relay. How far does each athlete run ?

Answers

25 metres. Because 1/10th of a kilometre is a 100 metres. And four athletes divided by 100 metres is 25 metres.

Answer:

25 meters.

Step-by-step explanation:

Let us suppose each athlete run x km.

Hence, four athlete will run 4x km.

Now, the distance of the relay race is 1/10 km

Thus, we have

[tex]4x=\frac{1}{10}[/tex]

Divide both sides by 4

[tex]x=\frac{1}{40}km[/tex]

Now, 1 km = 1000 meters. Thus, we have

[tex]x=\frac{1}{40}\times1000\\\\x=25[/tex]

Thus, each athlete run 25 meters.

what is the answer to 2(0.5c−1.5)−6=−2 please show work!!!!

Answers

ANSWER: c = 7

WORK:
2(0.5c - 1.5) - 6 = -2
c - 3 - 6 = -2
c - 9 = -2
c - 9+9 = -2+9
c = 7
2(0.5c - 1.5) = -2 + 6

2(0.5c - 1.5) = 4

0.5c - 1.5 = 4/2

0.5c - 1.5 = 2

0.5c = 2 + 1.5

0.5c = 3.5

c = 3.5/0.5

Lastly simplify

Answer: c = 7.

Why is it important to have complex carbohydrates before a big race?

(Again, not math. I know, its to get the answer faster..)

Answers

Complex Carbs are very useful because they are healthy and do not interfere with a race. They turn those into glucose and helps the energy be saved longer. 
Complex Carbohydrates are made up of sugar molecules strung together in long chains. Both simple and complex carbs can be turned into Glucose which is used as short term energy. This short term energy is great for short races, for marathons I suggest more lipids as well. The act of eating a lot of carbs the night before a race is called "Carb Loading"

Find the value of m in each equation below. Justify your answer.
(x^m × x^2)^3 (k^3)^5 = x^21k^15

Answers

The main properties we use in this problem are:

i) [tex]x^a \cdot x^b=x^{a+b}[/tex] (so, when we multiply 2 exponents of the same base, we add the exponents)

ii) [tex]({x^a})^b=x^{a \cdot b}=x^{ab}[/tex]


thus, 

[tex](x^m \cdot x^2)^3=({x^{2m}})^3=x^{2m \cdot3}=x^{6m}[/tex]

by first applying property i) then property ii)

also, [tex]({k}^3)^5=k^{15}[/tex], by property ii)



So we have:

[tex]({x^m \cdot x^2})^3 \cdot({k}^3)^5=x^{21} \cdot k^{15}\\\\x^{6m}\cdot k^{15}=x^{21} \cdot k^{15}[/tex], 


now we only have to compare the exponents.
