Answer:

the cost of 1 child ticket is $6.5 and the cost of 1 adult ticket is $9.5

Step-by-step explanation:

Given that:

the price of 4 adult tickets & 6 child tickets = $77

the price of  6 adult tickets & 4 child tickets = 83

then the price of 1 adult ticket and 1 child ticket will be:

Let assume that the cost of 1 adult ticket to be $p

Then;

the cost of 4 adult ticket = $4p

Similarly, the cost of 6 adult ticket = $6p

However, assuming that the cost of 1 child ticket is $q

Then;

the cost of 6 child ticket = $6q

the cost of 4 child ticket = $4q

∴

We can express them with their given prices that:

4p + 6q = 77    --- (1)

6p + 4q  = 83   --- (2)

From equation (1), let 4p = 77 - 6q

Then; [tex]p = \dfrac{77 - 6q}{4}[/tex]

replace the value of p into equation (2)

∴

[tex]6 \Big ( \dfrac{ 77 - 6q }{4}\Big) + 4q = 83[/tex]

[tex]\dfrac{462 - 36q}{4}+ 4q = 83[/tex]

[tex]115.5 - 9q + 4q = 83 \\ \\ 115.5 -5q= 83 \\ \\ 115.5 - 83 = 5q \\ \\ 32.5 = 5q[/tex]

[tex]q= \dfrac{32.5}{5}[/tex]

q = 6.5

Since q = 6.5, then using equation (1)

4p + 6(6.5) = 77

4p +39 = 77

4p = 77 -39

4p = 38

p = 38/4

p = 9.5

Thus, the cost of 1 child ticket is $6.5 and the cost of 1 adult ticket is $9.5

Answer: A rectangle is ALWAYS a parallelogram and not all parallelograms are rectangles. (ex. Rhombus, square are both parallelograms) So Ainsley is wrong.

Answer:

a. 2/3 = 0.67

b. 8/5 = 1.6

c. -5/2 = -2.5

d. 7/4 = 1.75

e. 9/2 = 4.5

f. -11/3 = -3.67

g. 13/5 = 2.6

h. -7/4 = -1.75

Step-by-step explanation:

Convirtiendo las fracciones dadas a decimales, tenemos:

a. 2/3 = 0.67

b. 8/5 = 1.6

c. -5/2 = -2.5

d. 7/4 = 1.75

e. 9/2 = 4.5

f. -11/3 = -3.67

g. 13/5 = 2.6

h. -7/4 = -1.75

Answer:

First convert all numbers into inches since that is the answer being solved for.

1 yard =36 inches

4.5 x 36 = 1,620 inches

1 foot = 12 inches

3 x 12 = 36 inches

36 + 8 = 44 inches

Now take 1,620 inches (starting ribbon measure) and subtract 44 inches (what was left over) to get the inches used to trim curtains.

1,620 inches - 44inches =

1,576 inches were used to trim the curtains.

Answer:

$1900.80

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 9.9%/100 = 0.099 per year,

then, solving our equation

I = 4800 × 0.099 × 4 = 1900.8

I = $ 1,900.80

The simple interest accumulated

on a principal of $ 4,800.00

at a rate of 9.9% per year

for 4 years is $ 1,900.80.
