Lina made 9 flower necklaces. Each necklace had 16 carnations and 10 hibiscus flowers. Which equation could be used to calculate the total number of flowers used for the flower necklaces? 9 × 16 × 10 = f (9 + 16) × (9 + 10) = f 9 × (16 × 10) = f (9 × 16) + (9 × 10) = f

(9 × 16) + (9 × 10) = f

Step-by-step explanation:

Lina made 9 flower necklaces.

We are told that :

Each necklace had 16 carnations and 10 hibiscus flowers.

Hence,

1 flower neck lace = 16 carnations + 10 hibiscus flowers

The total number of flowers used to make 9 flower necklaces is :

f = 9( 16 + 10)

f = (9 × 16) + (9 + 10)

f = 144 + 90

f = 234 flowers

Therefore, equation could be used to calculate the total number of flowers used for the flower necklaces is:

(9 × 16) + (9 × 10) = f

step-by-step explanation:

the shape,the size and the distance

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
