I solved this problem by setting 240/80 equal to x/100 . Once you set them equal to each other, multiply 240 and 100 and divide the product by 80 and you get 300.
Answer:
Please check the explanation.
Step-by-step explanation:
Given the points
Using the formula to determine the slope between (x₁, y₁) and (x₂, y₂) of the linear function
Slope = m = [y₂ - y₁] / [x₂ - x₁]
For example, let the points be
(x₁, y₁) = (1, 2)
(x₂, y₂) = (3, 4)
Determining the slope between
Slope = m = [y₂ - y₁] / [x₂ - x₁]
= [4 - 2] / [3 - 1]
= 2 / 2
= 1
Thus,
The slope of the line between the points (1, 2) and (3, 4) will be: m = 1
Answer:
(a) AD=6 cm
(b) 66 cm²
(c) 38 cm
Step-by-step explanation:
(a) To get the length of AD, we can use pythagoras on the triangle part. Let's say the dotted line intersects DC at E. Then since AB and DC are parallel, AD is equal to BE. EC = 8 cm simply by subtracting AB from DC (15-7=8).
Then pythagoras says that 8²+BC²=10². So BC = √(100-64) = 6. And since BC=AD, AD is also 6.
(b) Area of the rectangle DEBA is 7*6 = 42. Area of triangle ECB is base times half height: 8*3 = 24. Sum is 42+24 = 66 cm²
(c) Perimeter is 7+10+15+6 = 38 cm. Add all the side lengths.

Answer:
$119.32
Step-by-step explanation:
Leiff decides to buy his video game, with a price tag of $128, at this site
he will get the 15% discount when he checks out.
100-15= 85%
Discounted price=85% of 128 is 
Leiff pays 5.3% sales tax on the discounted price
5.3% is 0.053
sales tax amount=0.053 times 108.8=5.7664
So we add the sales tax amount and shipping fee

So $119.32 is the total amount
