Answer:

Beth's class left for the field trip at 7:13 A.M..

Step-by-step explanation:

To find out what time Beth's class left for the field trip, we need to subtract the time elapsed at the museum and the time it took them to drive there from 9:41 A.M.

The time elapsed at the museum was 1 hour and 33 minutes which is equivalent to 93 minutes.

To find out what time they left for the field trip, we need to subtract 55 minutes (the time it took them to drive there) and 93 minutes (the time they spent at the museum) from 9:41 A.M.

9:41 A.M. minus 55 minutes is 8:46 A.M..

8:46 A.M. minus 93 minutes is 7:13 A.M..

Therefore, Beth's class left for the field trip at 7:13 A.M..

I hope that helps!

Answer:

6:59am

Step-by-step explanation:

1 hour and 33 minutes = 93 minutes

55 minute ride to museum

93+55=148

60 minutes in 1 hour

148 divided by 60 = 2 hours 46 minutes

Time Left: 9:41

9.41-2.46

6.59

They left at 6:59am

(2/3)*75 = $50

I hope this is right! :)

Answer:

one solution

Step-by-step explanation:

Well, let's find out by solving the equation! I'll put it below and we can start looking at how to isolate x and see if there is one solution, no solution, or infinite solutions:

\(70-10x=-10+40\\\)

First, it's probably a good idea to combine like terms. Both -10 and 40 are like terms on one side of the equation, so we can combine them to get 30. Now our equation looks like this:

\(70-10x=30\)

Next, let's subtract 70 from both sides so we can get the x on one side:

\(70-70-10x=30-70\\-10x=-40\)

Finally, we can divide both sides by -10.

\(\frac{-10x}{-10} =\frac{-40}{-10} \\x=4\)

It looks like there is one solution. Hopefully that's helpful! :)

Answer:

The first click beetle went higher.

Step-by-step explanation:

The vertex is the minimum point of a parabola that opens upwards, or the maximum point of a parabola that opens downwards.

Since the height of each of the beetles at time, t seconds, is modelled as a parabola that opens downwards, the maximum height of each beetle is the y-value of the vertex.

The function representing the height, h, of the first beetle is:

\(h(t)=-16t^2+8t\)

We could complete the square to rewrite the function in vertex form, however the quickest way to find the vertex of a quadratic function in the form ax² + bx + c is to use the formula for the x-value of the vertex:

\(\boxed{x_{\sf vertex}=-\dfrac{b}{2a}}\)

Comparing  ax² + bx + c with the given function:

Therefore, substituting the values of a and b into the formula, the x-value of the vertex of h(t) is:

\(x_{\sf vertex}=-\dfrac{8}{2(-16)}=0.25\)

To find the y-value of the vertex, and thus the maximum height of the first beetle, simply substitute t = 0.25 into function h(t):

\(\begin{aligned}\implies h(0.25)&=-16(0.25)^2+8(0.25)\\&=-16(0.0625)+2\\&=-1+2\\&=1\end{aligned}\)

Therefore, the maximum height of the first beetle is 1 foot.

From inspection of the given graph modelling the height of the second beetle, we can see that the maximum y-value is approximately 0.76 feet.

As the height of the second click beetle is less than the maximum height of the first click beetle, the first beetle went higher.

Answer:

I do not agree with her

Step-by-step explanation:

You can find the answer by doing the keep change flip method. So keep the 6, chnage the sign to a multiplication sign, then flip the 2/3 to 3/2. Then you multiply and you get 18/2 which simplifies to 9.

Answer:63

Step-by-step explanation:

 multiply 72 by 7 then divide i by 8

(72×7)/8

=63

It's 63.

simplify the equation 7/8×72 multiple 7×9 solution is 63

Answer: In about 3 hours and 21 minutes the prices of the two stocks will be the same at $14.02

Step-by-step explanation: We can begin by calculating the value of stock A at noon by adding $.06 per hour or 3 hours, $0.18 to its 9am price. $13.64 + 0.18 = 13.82

Then set up the equation to find the point where the prices are equal:

x is the amount of time in hours.

.06x + 13.82 = -.11x + 14.39    

Add .11x to both sides and subtract 13.82 from both sides

.06x + .11x = 14.39 - 13.82

.17x = 0.57

x = 3.353 hours

To get minutes instead of a decimal, multiply .353 × 60 ≈ 21 minutes

The time is 3:21

The increase in price is for stock A is about $0.20

13.82 + .0.06(3.353) = $14.02

Stock B decreased by $0.37

14.39 - 0.11(3.353) = $14.02

Here are the pairs matched with their products:

- (-5)(4.2) matches with -21

- (-7)(-3) matches with 21

- (2.5)(-9) matches with -22.5

Pairs (4) and (5) do not have corresponding products in the given options.

Answer:

-17

Step-by-step explanation:

I will represent the question mark with the variable \(x\).

\(x - 11 + 12 = -16\)

To solve for \(x\), we need to isolate it.

To do this, subtract 12 from both sides.

\(x - 11 + 12= -16\\\underline{\textrm{ } \ \ \ \ \ \ \ \, -12} \ \, \, \, \, \ \underline{-12}\\x - 11 \ \ \ \ \ \: \ = -28\)

Then, add 11 to both sides.

\(x - 11 = -28\\\underline{\ \ \: + \, 11} \ \ \ \, \underline{+ \, 11}\\x \ \ \ \ \ \ \: = -17\)

\(x = -17\)

So, the integer that makes the equation true is -17.

Answer:

150

Step-by-step explanation:

To find a reasonable prediction for the number of times the event of landing on an odd number will occur when a fair 6-sided die is rolled 300 times, we can consider the probability.

Out of the six possible outcomes of rolling a fair 6-sided die, three of them are odd numbers (1, 3, and 5). Therefore, the probability of rolling an odd number on a fair 6-sided die is 3/6, which simplifies to 1/2 or 0.5.

To predict the number of times the event will occur, we can multiply the probability by the total number of rolls:

Number of times = Probability × Total number of rolls

Number of times = 0.5 × 300

Number of times = 150

Therefore, a reasonable prediction for the number of times the event of landing on an odd number will occur is 150.

Answer:

The first option, V ≈ 1607.7 in²

Step-by-step explanation:

Find the volume of the given cylinder.

\(\begin{center}\framebox{\parbox{4cm}{\textbf{Volume of a Cylinder:}\\[2ex]The volume of a cylinder with radius $r$ and height $h$ is given by the formula:\\[2ex]\center{$V = \pi r^2 h$} \\ \\}}\end{center}\)

Given:

r = 8 in

h = 8 in

π = 3.14

Find:

V = ?? in³

\(\hrulefill\)

Now solving,

Substitute the given values into the formula:

=> V = (3.14)(8)²(8)

Using a calculator to simplify:

=> V = 1607.68 in²

Rounded to the nearest tenth:

∴ V ≈ 1607.7 in²

Thus, the first option is correct.

4.88

1.

84 because PEMDAS(parenthesis/Exponents/Multiply/Divide/Add/Subtact) says you do parenthesis first. So you add 9 and 3 to get 12. The you do 12*7 to get 84.

the answers are the ones you chose. (the last 2) trust your gut, girl/boy. you got this. and i'm not saying the answer is that just to get the points. i checked myself and, yes, it is right. so keep going. you dont need brainly. your smart by yourself. you may be stuck on one or two things. thats when you use brainly. but if you already have an answer? trust yourself. you can do it.
