If it is 11:45 a.m., what will the time be 3 hours and 15 minutes later?4:15 p.m.
2:45 p.m.
3:15 a.m.
3:00 p.m.

Answers

Answer 1

Answer: If you would like to know what will the time be 3 hours and 15 minutes later, you can calculate this using the following steps:

11:45 a.m. + 3 hours and 15 minutes = 12:00 p.m. + 3 hours = 15:00 p.m. = 3:00 p.m.

The correct result would be 3:00 p.m.

A rectangular swimming pool with a flat bottom is 20 feet by 12 feet. How long will it take to fill the swimming pool to 5 feet if water is being pumped into the pool at 30 cubic feet per minute?

Answers

The given dimensions of the rectangular swimming pool are =

Length = 20 feet

Width = 12 feet

Height upto which the water should be filled up = 5 feet

So, the total volume of water needed to fill the pool will be =

$20*12*5=1200$ cubic feet

The water is pumped at a speed of = 30 cubic feet per minute.

So, to fill 1200 cubic feet, the time taken will be = $(1200)/(30) =40$

Hence, it will take 40 minutes to fill the pool.

20 feet * 12 feet * 5 feet
= 20 * 12 * 5 feet ^3
= 1200 feet^3

1200 feet^3 / (30 feet^3 / minute)
= (1200 / 30) minutes
= (120 / 3) minutes
= 40 minutes

What is the seventh term of (x + 4)8?A. 114,688x2

Answers

The (p+1)-th term of the Newton binomial expansion

$(a+b)^(n)$

is given by

$t_(p+1)=\dbinom{n}{p}\,a^(n-p)\,b^(p)$
__________________________

We want the 7th term. Hence, we set $p+1$ to be $7:$

$p+1=7~~\Rightarrow~~p=6$

Then, the 7th term is

$t_(7)=\dbinom{8}{6}\,x^(8-6)\,4^(6)\n\n\n t_(7)=(8!)/(6!\cdot (8-6)!)\cdot x^(8-6)\cdot 4^(6)\n\n\n t_(7)=(8\cdot 7\cdot \diagup\!\!\!\! 6!)/(\diagup\!\!\!\! 6!\cdot 2!)\cdot x^(2)\cdot 4^(6)\n\n\n t_(7)=(8\cdot 7)/(2\cdot 1)\cdot x^(2)\cdot 4^(6)\n\n\n t_(7)=28\cdot x^(2)\cdot 4,096\n\n \boxed{\begin{array}{c} t_(7)=114,688\,x^(2) \end{array}}$

Correct answer: $\text{A. }114,688\,x^(2).$

Is the ordered pair (–8, –7) a solution to the equation 3x + 10 = 2y? Show your work.

Answers

Answer:

yes

Step-by-step explanation:

Substitute x = - 8 and y = - 7 into the equation

If both sides are equal then (- 8, - 7) is a solution

left side = 3x + 10 = 3(- 8) + 10 = - 24 + 10 = - 14

right side = 2y = 2(- 7) = - 14

Since both sides are equal then (- 8, - 7) is a solution to the equation

Final answer:

The ordered pair (-8, -7) is a solution to the equation 3x + 10 = 2y. This is determined by substituting the values of the ordered pair into the given equation leading to -14 on both sides of the equation.

Explanation:

To determine if the ordered pair (-8, -7) is a solution to the equation 3x + 10 = 2y, we can substitute -8 for x and -7 for y in the equation.

This would result in 3*(-8) + 10 = 2*(-7), which simplifies to -24 + 10 = -14. So the left side of the equation equals -14, and the right side of the equation equals -14 as well. Because both sides equal the same value, the ordered pair (-8, -7)is a solution to the given equation.
