Answer:

the second one to the right or

-1*2*-3*4*-5

Step-by-step explanation:

Becuase the amount of negatives are odd so it’ll give you a negative, if the amount of negatives are ven, it’ll give you a positive, no matter how many positive numbers there are, it won’t change anything at all since positive *positive will give you positive and positive*negative will give you negative so a positive times any type of number, the sign will stay the same

Please help me. The original blueprint of the Moreno’s’ living room has a scale of 2 inches= 5 feet. The family wants to use a n

Svetradugi [14.3K]

Answer:

Part a) The scale of the new blueprint is $\frac{5}{8} \frac{in}{ft}$

Part b) The width of the living room in the new blueprint is $9.4\ in$

Step-by-step explanation:

we know that

The scale of the original blueprint is

$\frac{2}{5}\frac{in}{ft}$

and

the width of the living room on the original blueprint is 6 inches

<em>Find the actual width of the living room, using proportion</em>

$\frac{2}{5}\frac{in}{ft}=\frac{6}{x}\frac{in}{ft}\\ \\x=5*6/2\\ \\x=15\ ft$

<em>Find the actual length of the living room, using proportion</em>

$\frac{2}{5}\frac{in}{ft}=\frac{9.6}{x}\frac{in}{ft}\\ \\x=5*9.6/2\\ \\x=24\ ft$

<em>Find the scale of the new blueprint</em>, divide the length of the living room on the new blueprint by the actual length of the living room

$\frac{15}{24} \frac{in}{ft}$

simplify

$\frac{5}{8} \frac{in}{ft}$

<em>Find the width of the living room in the new blueprint, using proportion</em>

$\frac{5}{8}\frac{in}{ft}=\frac{x}{15}\frac{in}{ft}\\ \\x=15*5/8\\ \\x=9.4\ in$

Write and solve a division problem involving decimals.Explain how you know where to place the decimal point in the quotient.

defon

Mike has 10 and a half cookies (10.5). Mike wants to share these cookies with 5 friends. How many cookies does each friend get. The answer is 2.1 one (Or 2 and 1 crumb I guess lol). You place the decimal point where ever it was originally so you would place it after the 2 and before the one. It's been a while since I've done one of these problems so sorry if I'm a little rusty.
