Percent is $\frac{percent}{100}$ . and if the kicker makes $\frac{4}{5}$ , just compare the two like this:
$\frac{4}{5} = \frac{x}{100} \\
4*100=5*x\\
x=\frac{400}{5}=80$
So the percent of extra kicks the kicker made is 80%.

Compare the decimals by using the symbol < or >. a. 0.531 _____ 0.456 b. 0.63 _____ 0.47 c. 0.267 _____ 0.539 d. 0.07 ____

rodikova [14]

Answer:

0.531 > 0.456

0.63 > 0.47

0.267 < 0.539

0.07 < 0.7

Step-by-step explanation:

a. 0.531 _____ 0.456

compare the numbers from left to right

5 is greater than 4 so 0.531 greater than 0.456

0.531 > 0.456

b. 0.63 _____ 0.47

6 is greater than 4. 0.63 > 0.47

c. 0.267 _____ 0.539

2 is less than 5 . so 0.267 less than 0.539

0.267 < 0.539

d. 0.07 _____ 0.7

0 is less than 7

0.07 < 0.7

1. Your furniture store sells two types of dining room tables. The first, type A, costs $265 and you make a $25 profit on each o

Gnom [1K]

Let x represent the number of type A table and y represent the number of type B tables.
Minimize: C = 265x + 100y
Subject to: x + y ≤ 40
25x + 13y ≥ 760
x ≥ 1, y ≥ 1

From, the graph the corner points are (20, 20), (39, 1), (30, 1)
For (20, 20): C = 265(20) + 100(20) = $7,300
For (39, 1): C = 265(39) + 100 = $10,435
For (30, 1): C = 265(30) + 100 = $8,050

Therefore, for minimum cost, 20 of type A and 20 of type B should be ordered.

Sam has $1,000 to be distributed among two groups equally. Later the first part is divided among five children and second part i

katrin2010 [14]

Let x be the money distributed to the first group and y be the money distributed to the second group.

Then, x + y = 1000

Let c be the money distributed to one child in the first group and b be the money distributed to one brother in the second group.

Then, x = 5c and y = 2b

Hence 5c + 2b = 1000.

Regal theater in Tikahtnu sold 548 tickets to Moana on Sunday. A adult’s ticket was $6.50 while a child’s ticket was $3.50. In t

irga5000 [103]

Regal theater sold 321 adult tickets and 227 children tickets.

Step-by-step explanation:

Given,

Cost of each adult ticket = $6.50

Cost of each child's ticket = $3.50

Total tickets sold = 548

Total worth of sold tickets = $2881

Let,

x represent the number of adult tickets sold

y represent the number of child tickets sold

According to given statement;

x+y=548 Eqn 1

6.50x+3.50y=2881 Eqn 2

Multiplying Eqn 1 by 6.50

$6.50(x+y=548)\\6.50x+6.50y=3562\ \ \ Eqn\ 3$

Subtracting Eqn 2 from Eqn 3

$(6.50x+6.50y)-(6.50x-3.50y)=3562-2881\\6.50x+6.50y-6.50x-3.50y=681\\3y=681$

Dividing both sides by 3

$\frac{3y}{3}=\frac{681}{3}\\y=227$

Putting y=227 in Eqn 1

$x+227=548\\x=548-227\\x=321$

Regal theater sold 321 adult tickets and 227 children tickets.
