The basking shark can grow to a length of 30 feet. This is 176.47% of the maximum length of the beluga whale. Find the maximum length of the beluga whale. If necessary, round your answer to the nearest tenth.
a) 52.9ft
b) 17ft
c) 5.9ft
d)1.7ft

Answers

Answer:

b

Step-by-step explanation:

The maximum length of the beluga whale is 17 feet.

What is the percentage?

A percentage is a value per hundredth. Percentages can be converted into decimals and fractions by dividing the percentage value by a hundred.

Given, The basking shark can grow to a length of 30 feet.

This is 176.47% of the maximum length of the beluga whale.

Assuming the maximum length of a beluga whale is x feet.

So,  176.47% of x is 30 feet.

∴ (176.47/100)×x = 30.

1.7647x = 30.

x = (30/1.7647).

x = 17 feet.

Please please please help.

Answers

Answer and Step-by-step explanation:

A. Cruz is correct.

B. When we have a negative within a cube root, what we can do is move the negative sign from inside to outside the cube root.

[tex]\sqrt[3]{-64} = -\sqrt[3]{64}[/tex]

Now that we have a positive number within the cube root, we can solve the cube root itself.

So what is the cube root of 64?

The answer is 4, and since we have a negative sign outside of the cuberoot, we just put a negative sign, our answer is -4.

C. Aaron could've got it wrong because he did it a square root instead of a cuberoot of 64. Square root of 64 is 8, while cube root is 4.

Jacob could've gotten it wrong because he must've followed the fallacy that you cannot cube root a negative number.

Find the slope of the line passing through the pair of points.
(-4,5) and (0, 2)

Answers

Answer:

y = 3/-4x + 2

Step-by-step explanation:

Answer:

slope = [tex]-\frac{3}{4}[/tex]

Step-by-step explanation:

1) To find the slope between a pair of points, use the slope formula: [tex]\frac{y_2-y_1}{x_2-x_1}[/tex].

[tex]x_1[/tex] and [tex]y_1[/tex] represent the x and y values of one point the line passes through. [tex]x_2[/tex] and [tex]y_2[/tex] represent the x and y values of another point the line also passes through. We know the line passes through (-4,5) and (0,2). So, substitute their x and y values for the formula (following the appropriate order) and solve:

[tex]\frac{(2)-(5)}{(0)-(-4)} \\= \frac{2-5}{0+4} \\= \frac{-3}{4}[/tex]

Thus, the slope is [tex]-\frac{3}{4}[/tex]

What is 4/9 x 5/7 x 1/2

Answers

Answer:

0.16

Step-by-step explanation:

4*5*1=20

9*7*2=126

20/126=10/63

Answer:

10/63

Step-by-step explanation:

First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.

Javier works each weekend at an animal shelter. He earns $8 an hour. He is saving his earnings to go on a ski trip that costs $190.

Becca says that Javier must work at least 6 more hours to have enough money to go on the ski trip. Her work is shown below. Choose True or False about each statement

Becca's solution included all of the hours Javier worked on both weekends. (TRUE OR FALSE?)

Javier worked a total of 23 hours on both weekends. (TRUE OR FALSE?)

Javier earns $198 for 24 hours of work. (TRUE OR FALSE?)

Javier only needs to work one more hour to have enough money for his trip. (TRUE OR FALSE?)

Answers

Answer:

Becca's solution included all of the hours Javier worked on both weekends.

Step-by-step explanation:

Javier needs to work at least 6 more hours. He will earn:

6*8 = $48

He has already got:

$190 - $48 = $142

He worked:

142/8 = 18 hours (rounded)

Total he will have worked:

18 + 6 = 24 hours

Answer choices:

Becca's solution included all of the hours Javier worked on both weekends.

TRUE

Javier worked a total of 23 hours on both weekends.

FALSE. 23*$8 = $184 < $190

Javier earns $198 for 24 hours of work.

FALSE. 24*8 = $192

Javier only needs to work one more hour to have enough money for his trip.

FALSE. Becca says 6 more hours required.

what is the equation of the following? Someone could help me to understand this? thank you​

Answers

Answer:

y=(1/5)x

Step-by-step explanation:

First, we must find the slope of the line.

The slope of a line can be found using the formula: (y2-y1)/(x2-x1)

(3-0)/(15-0)

(3)/(15)

1/5

The slope is 1/5.

Next we find the y-intercept, or where the line crosses the y-axis. In this case, the y-intercept is 0.

This gives us the equation: y=(1/5)x
