Answer:

$x=17$

Step-by-step explanation:

$(6x+10)(x+17)(4x-34)$

$6x+10+x+17+4x-34=180$

Add:- $6x+x+4x=11x$

and $10+17-34=-7$

So, $11x-7=180$

Add 7 to both sides:-

$11x=187$

Divide both sides by 11:-

$\frac{11x}{11}=\frac{187}{11}$

$x=17$

Samuel can type nearly 40 words per minute. Use this information to find the number of hours it would take him to type 2000 word

It’s hard to tell because there isn’t a visual. My guess is that it’s ASA~ and SAS~ because T is congruent to P and A and F have the same angle

1000 was invested at 5.5% interest, compounded annually. After sometime the amount had grown to 1550. How long was the money inv

scZoUnD [109]

compound interest equation for annually compounded

$A=P(1+r)^t$

A=final amount

P=principal

r=rate in decimal

t=time in years

given that

A=1550

P=1000

r=5.5%=0.055

find t

$1550=1000(1+0.055)^t$

divide both sides by 1000

$1.55=1.055^t$

take ln of both sides

$ln(1.55)=ln(1.055^t)$

use ln rule $ln(a^b)=b(ln(a))$

$ln(1.55)=t(ln(1.055))$

divide both sides by ln(1.055)

$\frac{ln(1.55)}{ln(1.055)}=t$

using a calculator, we get that t=8.18544 yrs

so about 8.2yrs
