Answer:

1982 ÷ 18 = 109  

Step-by-step explanation:

The operator can't be addition, subtraction, or multiplication, because wherever you place it, the result is not 109.

The operator must be <em>division</em>. It must be in the fourth or fifth place, to make the numerator greater than the denominator.

In the fourth place,

Divide. Write in simplest form. 10 divided by 1 2/3 ?
adell [148]

Answer: 6

Step-by-step explanation: First rewrite 10 as 10/1 and 1 and 2/3 as 5/3.

Mixed numbers can be changed to improper fractions by multiplying the denominator by the whole number and then adding the numerator. We then put out numerator over our old denominator.

So we have 10/1 ÷ 5/3 or 10/1 × 3/5.

It's important to understand that dividing by a fraction is the same as multiplying by its reciprocal. In other words, we can change the division to multiplication and flip the second fraction.

Now multiplying across the numerators and across the denominators, we have 30/5. Notice however that 30/5 is not in lowest terms so we divide the numerator and the denominator by the greatest common factor of 30 and 5 which is 6 and we end up with 6.

Therefore, 10 ÷ 1 and 2/3 = 6.

Sam gave jen 1/2 of his jujubes. Jen ate 1/2 of the jujubes and gave the rest to klye. Kyle kept 8 of the jujubes and gave the l
USPshnik [31]

Answer:

Jen ate 18 jujubes

Step-by-step explanation:

Start with Kim. She was given 10. There is no remainder.

Kyle kept 8 from the total he was given, so Kyle had 18.

Let the number of Jujubes given to Jen = x

(1/2) x = 18    Multiply both sides by 2

2(1/2)x = 18*2

x = 36

Jen ate 1/2 of 36 which was 18.

Though you are not asked, Sam must have begun this with 2*36 = 72 Jujubes.

Determine the volume and the surface area of the three dimension figure
rodikova [14]

Answer:

Volume = 18 cm^3

Surface Area = 58 cm^2

Step-by-step explanation:

Find the volume with the formula V=w*h*l

W= width

H = height

L = length

W= 2cm

H= 1 cm

L= 9 cm

V= w*h*l

V= 2cm * 1 cm * 9cm

V= 18 cm^3

Find the surface area with the formula A= 2(w*l + h*l + h* w)

W= width

H = height

L = length

W= 2cm

H= 1 cm

L= 9 cm

A= 2(w*l + h*l + h* w)

A= 2(2cm*9cm + 1cm*9cm + 1cm* 2cm)

A= 2(29cm)

A= 58cm^2
