2 ratios equivalent to 3:12

Mathematics
2 answers:
Hatshy [7]2 years ago

Answer: 1 : 4 and 2 : 8

Step-by-step explanation: To find 2 different ratios that are equal to the ratio 3:12, we first rewrite the ratio 3:12 as the fraction 3/12. Notice that we can find 1 of our equal ratios by simply writing this fraction in lowest terms. if we divide both the numerator and denominator of 3/12 by their greatest common factor of 3, we get the equal ratio 1/4.

Now we can use 1/4 to find another equal ratio. If we multiply both the numerator and denominator of 1/4 by 2, we get the equal ratio 2/8.

Finally, remember to write these ratios using the same form as the original problem. 1 : 4 and 2 : 8.

Iteru [2.4K]

Answer:

\$36,945.28  

Step-by-step explanation:

we know that

The formula to calculate continuously compounded interest is equal to

A=P(e)^{rt}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest in decimal  

t is Number of Time Periods  

e is the mathematical constant number

we have  

t=25\ years\\ P=\$5,000\\ r=8\%=8/100=0.08

substitute the values in the formula

A=5,000(e)^{0.08*25}  

A=5,000(e)^{2}  

A=\$36,945.28

Lamont Gatling purchased a phone answering system for his home office. The list price was $99.86. He also purchased a 12-foot ha
Natali5045456 [20]

Answer:

$130.7086

Step-by-step explanation:

List price of phone answering system = $99.86

Handset cord = $8.95

Telephone wire = 45 cent/foot ; length = 50 feet

Rebate on phone system = $5

Store coupon =$1 of each accessory

Sales tax = 6% on final price

Price before coupon = (99.86 + 8.95 + (50*0.45)) =$131. 31

Number of accessories = 3

Total coupon = $5 + ($1 * 3) = $8

Price after coupon = final price : $131.31 - $8 = $123.31

Sales tax = 0.06 * $123.31 = $7.3986

Amount paid = $123.31 + $7.3986 = $130.7086

11Alexandr11 [23.1K]

Dj kay-cee: 50x+100

Dj fav fred: 30x+150

So, setting up the equation, you get that 50x+100=30x+150

So, 20x=50, and x=\frac{5}{2}

So after 2.5 hours, dj kay-kee and dj fab fred would charge the same amount.

The energy expended by a bird per day, E, depends on the time spent foraging for food per day, F hours. Foraging for a shorter t
Veronika [31]

Answer:

Therefore F=2.387 hours gives a minimum value of energy expenditure E.

Step-by-step explanation:

Given that,

The energy expended by a bird per day

E=0.25 F+\frac{1.7}{F^2}

Differentiating with respect to F

E'=0.25 -\frac{3.4}{F^3}

Again differentiating with respect to F

E''=\frac{10.2}{F^4}

Now set E'=0

0.25 -\frac{3.4}{F^3}=0

\Rightarrow \frac{3.4}{F^3}=0.25

\Rightarrow F^3=\frac{3.4}{0.25}

\Rightarrow F=2.387

Now E''|_{F=2.387}=\frac{10.2}{2.387^4}>0

Since, E''>0 at F=2.387, So at F=2.387 , E has minimum value.

Therefore F=2.387 hours that minimizes energy expenditure.
