Answer:
$180
Step-by-step explanation:
Since the cost of the telescope with the 30% discount is $126 then $126 is 70% of the original price. Remember 100-30=70. To find the original price set up a proportion with these values:
Solve for the original price by cross multiplying numerator with denominator.
x(70) = 126(100)
70x = 12600
x= $180
If the formula is V= Ab x H
then the base and height is 4 and 7.5 because it doesn’t need to be the bottom so you multiply 7.5 x 4= 30 but we have to half it since it’s a triangle which is 15 and then multiply 10 which gives us 150 cm squared.
Answer:
157.6m
Step-by-step explanation:
Given
Horizontal distance = 181m
Length of the rope =240m
To know how high above Kayla was, we will use the Pythagoras theorem.
According to the theorem;
d² = x²+y²
x is the horizontal distance
y is the vertical distance
d is the length of the rope
Substitute
240² = 181²+y²
y² = 240²-181²
y² = 24839
y = √24839
y = 157.6m
Hence the boat is 157.6m above Kayla
<u>answer:</u> the slope of the line would be 5
<u>explanation:</u>
slope-intercept formula ==> y = mx + b
m would be the slope, and b would be the y-intercept. therefore the answer would be 5
hope this helps! ❤ from peachimin
n would be replaced by 50 so it would read 50-8=42!
