Answer:
97
Step-by-step explanation:
Do 150 divided by 20 which is 7.5 then do 13 x 7.5 which is 97.5 BUT you cant win 97.5 times do I believe that it would be 97 (if that's not an option, do 98)
Using the speed - distance relationship, the number of minutes it will take Josiah to cover a distance of 2.5 miles is 30 minutes.
<u>Calculating Josiah's speed</u> :
- <em>Speed = (distance ÷ time) </em>
Speed = (3 ÷ 36) = 0.08333 miles per minute.
<u>Time taken to cover a distance of 2.5 miles</u> :
- <em>Time taken = (Distance ÷ Speed) </em>
Time taken = (2.5 ÷ 0.08333) = 30 minutes
Therefore, it will take 30 minutes for Josiah to cover a distance of 2.5 Miles

Y = mx + b
Where m is the slope and b is the y-intercept
As you can already see it passes through the origin so b (the y-intercept) is (x, 0)
And the slope were it’s rise/run so it goes up 2.5 units and to the right 1 unit so it’s 2.5/1 = 2.5
m = 2.5
let's say is 16% of "x", meaning "x" is the 100%.
we know "x" is 100% and 16% of it is 10, so
Step-by-step explanation:
it is a rectangle (usually).
so,
2×length + 2×width = 80
therefore, length + width = 40
length×width = 384
length = 384/width
384/width + width = 40
384 + width² = 40×width
width² - 40×width + 384 = 0
the general solution for such a square equation is
x = (-b ± sqrt(b² - 4ac))/(2a)
in our case
x = width
a = 1
b = -40
c = 384
width = (40 ± sqrt((-40)² - 4×1×384))/(2×1) =
= (40 ± sqrt(1600 - 1536))/2 =
= (40 ± sqrt(64))/2 = (40 ± 8)/2 =
= 20 ± 4
width1 = 20 + 4 = 24 cm
length1 = 40 - 24 = 16 cm
width2 = 20 - 4 = 16 cm
length2 = 40 - 16 = 24 cm
so, both solutions are the same.
the greeting card is 24×16 cm. or 16×24, depending on how you are holding it.
