Of the flowers on Jill's front lawn,2/5 are tulips. Of the tulips,5/8 are yellow. What fraction of the flowers on Jill's front lawn are yellow tulips. A 18 B 1/4 C 1/2 D 7/13

Answers

Answer 1

Answer: 2/5 of the flowers are tulips, 5/8 of the tulips are yellow. Yellow tulpis are 5/8 of 2/5 of the flowers.

$(5)/(8) \ of \ (2)/(5)=(5)/(8) * (2)/(5)=(1)/(8) * (2)/(1)=(2)/(8)=\boxed{(1)/(4)} \Leftarrow \hbox{answer B}$

Tanya kicks a ball into the air. The function that models this scenario is f(t) = –16t2 + 96t, where h is the height of the ball in feet and t is the time seconds.When will the ball hit the ground?

Answers

Answer:

the ball hit the ground at $t=6\ sec$

Step-by-step explanation:

we have

$h(t)=-16t^(2) +96t$

This is the equation of a vertical parabola open downward

The vertex is a maximum

we know that

The x-intercept of the function is the value of t when the value of h(t) is equal to zero

The ball hit the ground when h(t) is equal to zero

equate the function to zero and solve for t

$0=-16t^(2) +96t$

Factor the leading coefficient

$-16t(t -6)=0$

The solutions are

$t=0, t=6\ sec$

therefore

the ball hit the ground at $t=6\ sec$

I guess the function is h(t) = -16t^2 + 96t (instead of f(t) )

When the ball hits the groung h(t) = 0

Then solve the equation for t

- 16t^2 + 96 t = 0

Divide by -16

t^2 - 6t = 0

t(t-6) = 0

t =0 is when the ball is kicked off

t = 6 is the answer.

What is the probability of choosing a card that does not have a digit 1 on it? Give the answer as a fraction numbers: 1,2,3,4,5,6,7,8,9,10

Answers

Final answer:

The probability of selecting a number, from the set {1,2,3,4,5,6,7,8,9,10}, that does not have the digit '1' on it, is 9 out of 10, or 9/10. Each selection is an independent event.

Explanation:

The subject of this question is Probability, a branch of Mathematics. Given the numbers 1,2,3,4,5,6,7,8,9,10, we have ten numbers in total, and only one of these numbers (1) is what we're trying to avoid. Hence, the probability of choosing a number that does not have the digit 1 on it is 9 (total numbers) - 1 (digit 1) divided by 10 total numbers, giving us a final answer of 9/10.

Probability can be represented as a fraction, where the numerator represents the favorable outcomes and the denominator represents the total number of outcomes.

Choosing each individual number is an independent event, meaning the outcome of each selection does not affect the probability of the subsequent selection.

What is the exact volume of the cone 4 in and 7 in

Answers

Answer: V=205.25 cubic inches.

Step-by-step explanation:

For the given cone height = 4 in and radius= 7 in .Volume of any cone can be calculated by the formula :

V= $(1)/(3) \pi r^(2) h$

Substituting the values of r and h we have:

V= $(1)/(3) \pi 7^(2) .4$

Solving for V we have:

V=205.25 cubic inches.

V = (1/3) *pi* (7)^2 * 4

V = ( 196 pi ) / 3
