A rectangle room is 12 1/2 feet long and 10 1/3 feet wide. what is the area of the room

Veronika [31]

Answer:

129 1/6 feet

Step-by-step explanation:

Formula for area is L*W

1. convert the mixed numbers to improper fractions

12 1/2 feet = 25/2

10 1/3 feet = 31/3

2. multiply numerator by numerator (25*31 = 775

3. multiply denominator by denominator (2*3=6

4. convert improper fraction 775/6 into a mixed number by dividing 775 by 6.

5. 775/6 = 129 r. 1 or 129 and 1/6

X = y = (3y + 2) 4x° 52°

antiseptic1488 [7]

TO GET Y I WILL USE THE REASON SUM OF ANGLES IN A TRIANGLE:

$52 + 90 +( 3y + 2) = 180 \\ 52 + 90 + 2 +3 y = 180 \\ 3y = 180 - 90 - 52 - 2 \\ 3y = 36 \\ \frac{3y}{3} = \frac{36}{3} \\ y = 12$

y=12°

TO FIND X I WILL USE THE REQSON ALTERNATE ANGLES

$4x = 52 \\ \frac{4x}{4} = \frac{52}{4} \\ x = 13$

x=13°

THEE ANGLES ARE INSIDE THE PARALLEL LINES :NOTE.

(-1,2p³q)(10p²r²)= Help me

MaRussiya [10]

For this case we have the following expression:
$(-1.2p^3q)(10p^2r^2)$
When making multiplication, the first thing you should keep in mind is the following property:
Same basis, the exponents are added.
We have then:
$-12p^{3+2}r^2q$
Rewriting we have:
$-12p^{5}r^2q$
Answer:
The simplified expression is given by:
$-12p^{5}r^2q$
