Answer:

For Friday, 22% of the check in's happened on that day. For Saturday, 24% of the check in's happened on that day. For both days combined, 46.66% of the check in's happened for both.

Step-by-step explanation:

Overall there were 90 check ins. Since 20 happened on Friday, it would be 20/90, which is 22%. Saturday, 22 check ins happened, so it would be 22/90, which is 24%. Overall, between Friday and Saturday, 42 check in's happened, so it would be 42/90, which is 46.66%.

Chase and sara went to the candy store. Chase bought 5 pieces of fudge and 3 pieces of gum for 5.70. Sara bought 2 pieces of fud

tamaranim1 [39]

Let, price of fudge and gum is x and y respectively.

Converting given statements into mathematical equation.

We get :

5x + 3y = 5.70 ....1)

2x + 10y = 3.60 ....2)

Solving equation 1 and 2, we get :

x = $1.05 .

y = $0.15 .

Price of buying 20 pieces of fudge and 20 pieces of bubble gum is :

P = 20( 1.05 ) + 20( 0.15 )

P = $24

Hence, this is the required solution.

Answer:

${5}^{8} {x}^{6}$

Step-by-step explanation:

$\bigg( \frac{125 {x}^{ - 3} }{ {5}^{ - 3} \times 25 \times {x}^{ - 6} } \bigg)^{2} \\ \\ = \bigg( \frac{ {5}^{3} {x}^{ - 3} }{ {5}^{ - 3} \times {5}^{2} \times {x}^{ - 6} } \bigg)^{2} \\ \\ = {( {5}^{3 + 3 - 2} {x}^{ - 3 + 6} })^{2} \\ = {( {5}^{6 - 2} {x}^{3} )}^{2} \\ = {( {5}^{4} {x}^{3}) }^{2} \\ = {5}^{4 \times 2} {x}^{3 \times 2} \\ = {5}^{8} {x}^{6} \\$
