Answer:

B and E

Step-by-step explanation:

∠ ECD = ∠ ACB ( vertically opposite angles are congruent ) , then

12x - 9 = 6x + 27 ( subtract 6x from both sides )

6x - 9 = 27 ( add 9 to both sides )

6x = 36 ( divide both sides by 6 )

x = 6 → B

Then

∠ ACB = 6x + 27 = 6(6) + 27 = 36 + 27 = 63° → E

The first floor of a house consists of a kitchen, playroom, and dining room. The areas of the kitchen, playroom, and dining room
lozanna [386]

Answer: See explanation

Step-by-step explanation:

From the question, we are informed that the areas of the kitchen, playroom, and dining room are in the ratio 4 : 3 : 2 and that the combined area of these three rooms is 189 square feet.

Therefore, Kitchen area = 4/(4+3+2) × 189 = 4/9 × 189 = 84 square feet

Playroom area = 3/(4+3+2) × 189 = 3/9 × 189 = 63 square feet

Dining room area = 2/(4+3+2) × 189 = 2/9 × 189 = 42 square feet

A new toy hits the local store. Sales (in hundreds) increase at a steady rate for several months, then decrease at about the sam
Montano1993 [528]

Answer:

Option A.

Step-by-step explanation:

It is given that, sales (in hundreds) for several months can be modeled by the function:

S(m)=-0.625|m-8|+5

We need to find the month in which 400 toys were sold.

Substitute S(m)=4 in the given function.

4=-0.625|m-8|+5

4-5=-0.625|m-8|

-1=-0.625|m-8|

\dfrac{-1}{-0.625}=|m-8|

1.6=|m-8|

Now,

\pm 1.6=m-8

1.6=m-8 or -1.6=m-8

1.6+8=m or -1.6+8=m

9.6=m or 6.4=m

Approx the value to the next whole number.

m\approx 10 or m\approx 7

It means, 400 toys were sold on 7th and 10th month.

Therefore, the correct option is A.
