If three bags of bird seed cost $14.16 how much would 14 bags cost?

olchik [2.2K]

<span>So we wan't to know how much would 14 bags of seeds cost if three bags cost 14.16$. What we wan't first is the price of only one bag of bird seeds and lets call it x. To get that we need to divide the cost of three bags of seeds by 3 and we get that x=14.16$/3=4.72$. So now that we know how much one bag of seeds costs we can simply multiply it by 14 and get our answer: 14*4.72$=66.08$</span>

Alvin has $760 less invested in 7% than he has at 5%. If his annual income from these two investments is $51.20, how much does h

kondor19780726 [428]

Answer:

Alvin invested $110 at rate of 7% and invested $870 at rate of 5%

Step-by-step explanation:

we know that

The simple interest formula is equal to

$I=P(rt)$

where

I is the Interest Value

P is the Principal amount of money to be invested

r is the rate of interest

t is Number of Time Periods

in this problem

Let

x------> the amount of money invested at rate of 5%

At rate of 7%

we have

$t=1\ years\\ P=(x-\$760)\\r=0.07$

At rate of 5%

we have

$t=1\ years\\ P=x\\r=0.05$

substitute in the formula

$51.20=(x-760)(0.07*1)+(x)(0.05*1)$

$51.20=0.07x-53.2+0.05x$

$51.20+53.2=0.12x$

$x=104.4/0.12=\$870$

therefore

Alvin invested ($870-$760)=$110 at rate of 7%

Alvin invested $870 at rate of 5%

Prove that ACD is an Isosceles triangle.

Finger [1]

It doesn’t look like an isosceles angle though- you can tell the legs aren’t congruent and just by looking at they way the 90 degree angle indication is split up

I might be wrong
