Answer:

17: 25in²

18. 53m²

19. 21.6cm²

20. 20.8km²

Step-by-step explanation:

Formula for area of a parallelogram

Area = Base Length x Height

For 17

Given Base Length: 5 in

Given Height: 5 in

( Using the formula stated above ) area = 5 * 5 = 25

Hence the answer to #17 is 25in²

For 18

Given Base Length: 10 m

Given Height: 5.3 m

( Using the formula stated above ) area = 5.3 * 10 = 53

Hence the answer to #18 is 53m²

For 19

Given Base Length:  5.4 cm

Given Height: 4 cm

( Using the formula stated above ) area = 5.4 * 4  = 21.6

Hence the answer to #19 is 21.6cm²

For 20

Given Base Length: 5.2 km

Given Height: 4 km

( Using the formula stated above ) area = 5.2 * 4 = 20.8 km

Hence the answer to #20 is 20.8km²

A number when divided by 780 gives remainder 38 .What
baherus [9]

Given:

A number when divided by 780 gives remainder 38.

To find:

The reminder that would be obtained by dividing same number by 26.

Solution:

According to Euclis' division algorithm,

a=bq+r                ...(i)

Where, q is quotient and 0\leq r is the remainder.

It is given that a number when divided by 780 gives remainder 38.

Substituting b=780,\ r=38 in (i), we get

a=(780)q+38

So, given number is in the form of 780q+38, where q is an integer.

On dividing 780q+38 by 26, we get

\dfrac{780q+38}{26}=\dfrac{780q}{26}+\dfrac{38}{26}

\dfrac{780q+38}{26}=30q+\dfrac{26+12}{26}

\dfrac{780q+38}{26}=30q+\dfrac{26}{26}+\dfrac{12}{26}

\dfrac{780q+38}{26}=30q+1+\dfrac{12}{26}

Since q is an integer, therefore (30q+1) is also an integer but \dfrac{12}{26} is not an integer. Here 26 is divisor and 12 is remainder.

Therefore, the required remainder is 12.

A radio station had 141 tickets to a concert. They gave away 2 times as many tickets to listeners as to employees. How many tick
erica [24]

Answer:

Option C: 47 tickets

Step-by-step explanation:

Given that:

Tickets given to employees = 1 part

Tickets given to listeners = 2 parts

This means 141 tickets are totally divided into 3 parts so:

1 part = 141/3

1 part = 47

So now,

Tickets given to employees = 1 part = 47 tickets

Tickets given to listeners = 2 parts = 47 *2 tickets = 94 tickets

I hope it will help you!
