Answer: $10
Step-by-step explanation:
Assume the price of the phone case is x.
Assume the price of the charging cord is y.
Discounted price for phone case : 15% * x
= 0.15x
Discounted price for charging cord = 0.15y
Expression is therefore:
0.15x + 0.15y = 4.20
0.15 * 18 + 0.15y = 4.20
2.7 + 0.15y = 4.20
0.15y = 4.2 - 2.7
y = 1.5/0.15
y = $10

As you have a 1/2 chance of getting what you want when you flip the coin, to get heads, heads, tails, tails will be 1/2 x 1/2 x 1/2 x 1/2. Working our way down the line, 1/2 x 1/2 = 1/4, 1/4 x 1/2 = 1/8, and 1/8 x 1/2 = 1/16. Jack will get heads, heads, tails, tails 1/16 of the time.
Answer:
The dimensions of the fort in the drawing is 7 in by 5.5 in
Step-by-step explanation:
A scale can be used to either increase or decrease the size of a given object.
From the question, Brennan used a scale of 3 feet to 1 inch.
scale = 
The dimensions of the fort are 21 ft by 16.5 ft. Thus, to determine the dimensions of the drawing;
= 
y = 
= 7 in
Also,
= 
z = 
= 5.5 in
Dimensions = y by z = 7 in by 5.5 in
Therefore, the dimensions of the fort in the drawing is 7 in by 5.5 in.
