What is the product of 4n^+3=7n?

Answers

Answer 1

Answer: so if you solve for n
4n^2+3=7n
make into trinomial
subtract 7n from both sides
4n^2-7n+3=0
if we can factor this, then we can asume that the factors are equal to zero becase if
xy=0 then assume x and/or y=0 so

to factor an equation in ax^2+bx+c where a is greater than 1 then
b=t+z
a times c=t times z
to factor 4n^2-7n+3 you do
4 times 3=12
what 2 numbers multiply to get 12 and add to get -7
the numbers are -3 and -4 so
split up the -7
4n^2-4n-3n+3
group
(4n^2-4n)+(-3n+3)
undistribute
(4n)(n-1)+(-3)(n-1)
reverse distributive property
ab+ac=a(b+c)
(4n-3)(n-1)=0
set each to zero
4n-3=0
add 3 to both sides
4n=3
divide both sides by 4
n=3/4

n-1=0
add 1 to both sides
n=1

n=3/4 or 1

A car fits onto a golden rectangle with a length of 12 ft. What is the car's width? Write your answer in simplified radical form and rounded to the nearest tenth of a foot.

Answers

basically, it is when legnth is $(1+ √(5) )/(2)$ the width

legnth=12
legnth= $(1+ √(5) )/(2)$ times width

12= $(1+ √(5) )/(2)$ times width
multiply both sides by 2
24= $1+ √(5)$ times width
subtract 1
23=√5 times width
divide both sides by √5
23/(√5)=width
multiply by (√5)/(√5) to rationalize denomenator
$(23 √(5) )/(5)$ =width

aprox 10.28 so 10.3 ft

w= $(23 √(5) )/(5)$ ft or aprox 10.3ft

Scott has $500 in the bank. He withdraws the same amount of money each week for 12 weeks, at which point he has $20 left in the bank. How much money did he withdraw each week?

Answers

Scott knew that the only chance we would have to answer this problem would be if he kept his money in a bank that pays no interest, so that's what he did. The bank simply stored his money in a mayonnaise jar under a tightly-guarded mattress, and he was allowed to come in and take some out of it each week.

He started with $500. He withdrew (500 - 20) = $480 in 12 weeks.

So he must have come in and picked up 480/12 = $40 each week.

There are 5280 feet in a mile how many feet are there in a marathon which is 26.2 miles

Answers

Answer:

138,336 feet

Step-by-step explanation:

To determine the number of feet in a marathon, multiply the number of feet in 1 mile by the number of miles.

If 1 miles has 5,280 feet, then 26.2 miles will have 26.2(5280) = 138,336 feet.

19 of the 23 participants in a triathlon are men and the rest are women. What is the ratio of the number of women participating to the total number of participants?

Answers

Answer:

3:23

Step-by-step explanation:

If 19 of the 23 participants in a triathlon are men then that means there are 4 participants that are women

so the ration would be 4 women for the 23 participants

Final Answer:

The ratio of the number of women participating to the total number of participants in the triathlon is 4:23.

Explanation:

In a triathlon, there are 23 participants in total, with 19 of them being men. To find the ratio of women to the total number of participants, we first need to determine the number of women participating.

To do this, subtract the number of men (19) from the total number of participants (23):

23 (total participants) - 19 (men) = 4 women

Now that we know there are 4 women participating, we can calculate the ratio:

Number of women : Total number of participants

4 : 23

So, the ratio of the number of women participating to the total number of participants is 4:23.
