Answer:
30 yellow straws and 45 red straws
30:45
Step-by-step explanation:
Make a ratio:
2:3, 2 being the yellow straw and 3 being the red straws
They are now asking how many red if there are 30 yellow straws
2:3 = 30:x
You could either cross multiply or simply do 30 ÷ 2 = 15 then 15 × 3 = 45. Your answer is 45
<u>Cross </u><u>multiplying</u>
2x = 90
90 ÷ 2 = 45
Answer:
percent means <u>per hundred </u>
Between the 100 squares, 60 of them are shaded
so you do 60/100
it's kind of like correcting tests, you have 100 questions, you got 80 of them right so its going to be 80/100
when you calculate percentage, you do the fraction x 100
so it's 60/100 = 0.6 x100 = 60%
hope that answers your question

Step-by-step explanation:
Answer:
The diagonal must be 17 ft
Step-by-step explanation:
To determine the diagonal, we will use the Pythagorean theorem. That is for right triangles (which means the angle is 90 degrees)
a^2 + b^2 =c^2
where a and b are the legs and c is the hypotenuse
a = 8 ft and b = 15 ft because these are the sides of the wall and the hypotenuse will be the diagonal
8^2 + 15^2 = c^2
64+225 = c^2
289 = c^2
Take the square root of each side
sqrt(289) = sqrt(c^2)
17 =c
The diagonal must be 17 ft
You take the derivative of the position equation s(t) = -3 + 4
and you get v(t) = 8t
now plug in 5
v(5) = 40
40 m/s
is your answer
