PLEASE HELPPPP

Answers

Answer: The dolphin's average speed is 3 mph

Step-by-step explanation: The basic equation is Speed = Distance ÷ Time

pls help I'm so confused X+8 What is the solution of 5x-1 > O? O x5-8 or X> 5 1 0x 5 x8 1 0 -85 0 -8 < X < 7

Answers

Step-by-step explanation:

(x + 8) / (5x - 1) > 0

Multiply both sides by (5x - 1)², which is always positive for all real values of x in the domain.

(x ≠ 1/5)

=> (x + 8)(5x - 1) > 0

=> x < -8 or x > 1/5.

The ratio of the measures of the three angles of a triangle is 4:5:9. Find the measure of the largest angle of the triangle.

Answers

Answer:

[tex]90^{\circ}[/tex]

Step-by-step explanation:

The interior angles of all triangles sum up to [tex]180^{\circ}[/tex]. Therefore, we can write the following equation:

[tex]4x+5x+9x=180[/tex], where [tex]x[/tex] is some constant.

Combining like terms, we have [tex]18x=180,\: x=10[/tex].

Therefore, the angles of this triangle are [tex]4(10)=40^{\circ}, \: 5(10)=50^{\circ}, \: 9(10)=90^{\circ}[/tex], the largest of them being [tex]\fbox{$90^{\circ}$}[/tex].

If an object is propelled upward from a height of 48 feet at an initial velocity of 96 feet per second, then its height after t seconds is given by the equation h(t)= -16t2+96t +48, where height is in feet. After how many seconds will the object reach a height of 192 feet?

Answers

Answer:

the number of seconds to reach the height is 3 seconds

Step-by-step explanation:

The computation of the seconds that reach the height is as follows;

Given that

h = -16t^2 + 96t + 48

here

H = 192 feet

So,

192 = -16t^2 + 96t + 48

-16t^2 + 96t - 144 = 0

Divide by -16

t^2 - 6t + 9 = 0

t^2 - 3t - 3t + 9

t(t - 3) - 3(t - 3)

t = 3 seconds

Hence, the number of seconds to reach the height is 3 seconds

Shawn is playing a game with a set of cards. Half of them are blue and the other half are yellow. In the game, the player guesses the color of the top card, looks at the card, and returns the card to the deck. The player continues to do this, shuffling the deck after each guess.

Shawn has guessed the first three attempts as "blue” and has been correct on each guess. He says he will guess "yellow” for the next card since a yellow card is due to happen. Is Shawn’s reasoning correct?

Yes, Shawn has guessed well so far, so it is clear that he cannot miss.
No, all of the cards have been blue so far, so the next one must also be blue.
Yes, half of the cards are yellow, so the fourth card should be yellow to compensate for the first three cards being blue.
No, the law of large numbers says that the proportion of yellow cards should approach the true probability after many trials.

Answers

Answer:

50 is the answer to this question

Answer:

Step-by-step explanation:

Well, you're having trouble with how it's supposed to be 50 right? So I suggest breaking it down a little bit.

As you see:

1100 ÷ 22

1100 and 22 are both divisible by 2 so if we divide both numbers by 2 you get:

550 ÷ 11

now try solving from there!!

If you still don't get it here:

firstly 11 goes into 5 zero times so put nothing

next does 11 go into 55? Yes! it does so how many times does it go into 55?

well let's see: 11 + 11 + 11 + 11 + 11 = 55

now if we count how many 11s there are there is 5! so then you put:

now lets see the next number is 0 and does 11 go into 0? Nope! so we just put:

50 and that is your answer!!

Answers

The total money would Gavin have after 10 weeks of savings is $ 170 and the required expression is 100 + 7w

Mathematical expression:

A mathematical expression is a combination of numbers, symbols, and operators that represents a mathematical relationship or calculation. It is written in a way that follows specific rules of mathematical notation, such as using parentheses to indicate the order of operations.

Here we have

Gavin is saving up to buy a new phone.

He already has $100 and can save an additional $7 per week using money from his after-school job

Let us assume that he worked for 'w' weeks

The amount earned for 'w' weeks = 100 + 7w

Hence, the required expression is 100 + 7w

The total amount saved in 10 weeks = 100 + 7(10) = $ 170

Therefore,

The total money would Gavin have after 10 weeks of savings is $ 170 and the required expression is 100 + 7w

Which of the following values of x makes this equation true? (-4x – 3) - (7x - 3) = 22

Answers

Answer:

Step-by-step explanation:

Here you go mate

Step 1

(-4x-3)-(7x-3) =22 Equation

Step 2

(-4x-3)-(7x-3) =22 Simplify

-11x=22

Step 3

-11x=22 Divide

Answer

x=-2

Now we have to,

→ find the required value of x.

Then the value of x is,

→ (-4x - 3) - (7x - 3) = 22

→ -4x - 3 - 7x + 3 = 22

→ -11x + 0 = 22

→ x = -22/11

→ [ x = -2 ]

Thus, the value of x is -2.

Jane works at The Bottling Company. She needs to put 8,500 bottles of water into cases. So far she has put 2,136 in cases. How many cases can Jane fill with the remaining bottles? How many bottles will be left?

Answers

Answer:

6364 cases

6364 bottles are left

Step-by-step explanation:

From the question, we are given the following

Total bottles of water = 8500bottles

Total cases filled = 2136cases

Required

Number of cases Jane can film with the remaining bottle.

Number of cases Jane can fill = 8500-2136

Number of cases Jane can fill with the remaining bottle= 6364 cases

Number of bottles left = number of cases Jane have left to fill.

Hence;

Number of bottles left = 6364 bottles
