10. The fifth term of an arithmetic sequence is 11 and the tenth term is 41. What is the first term?

9966 [12]

$a_{5}=a+4d=11\\a_{10}=a+9d=41$

Solve the above equations,

$a_{10}-a_{5}=41-11\\a+9d-a-4d=30\\5d=30\\d=6\\a=11-24=-13$

First term is -13.

Lisa wants to frame her little brothers drawing as a gift to her mother.the rectangle drawing is 43.5 centimeters by 934 millime

konstantin123 [22]

Answer:

Lisa will need $273.8\ cm$ of wood framing

Step-by-step explanation:

we know that

The perimeter of rectangle is equal to

$P=2(b+h)$

In this problem we have

$b=43.5\ cm$

$h=934\ mm$

convert to cm

Remember that $1\ cm=10\ mm$

$h=934\ mm=934/10=93.4\ cm$

substitute the values and solve the perimeter

$P=2(43.5+93.4)=273.8\ cm$

Two cars traveled equal distances in different amounts of time. Car A traveled the distance in 2 h, and Car B traveled the dista

irakobra [83]

Answer: Car B traveled 60 mph.

Step-by-step explanation:

A= B-15

A: (B - 15)(2 hr)=D

B: (B)(1.5)=D

Since B and A traveled the same distance you can plug in 1.5B for D.

2B - 30 = 1.5B

-1.5B +30 = -1.5B

——————+30—

2(0.5B) = 2(30)

B = 60 mph
