A scientist studied the migration patterns of two types of whales. The humpback whale traveled 2,000 miles in 25 days. The gray whale traveled 2,250 miles in 30 days. Assuming the humpback whale travels the same distance each day, what is the unit rate for the humpback whale in miles per day?

Answer:

m 1= 113 i think :)

Step-by-step explanation:

180 - 67

Answer:

it should total 180 degrees

so 160-67 is 113

Answer:

The correct answer would be 3x/5y

Step-by-step explanation:

You are substracting, and the denominator is the same for both 5x/5y and 2x/5y, so it will remain the same (5y). This only leaves you needing to substract 5x-2x, which equals 3.

5x/5y-2x/5y= 3x/5y

Step-by-step explanation:

[tex]\frac{5x}{5y}-\frac{2x}{5y}\\ \frac{5x -2x}{5y}\\ \frac{(5-2)x}{5y} \\ \frac{3x}{5y}[/tex]

[tex]\frac{3x}{5y} \\[/tex]

Step-by-step explanation:

use the FOIL method!

From both percentages, we can see that -83.3% is greater than -86.67%, hence, −5/6 > −13/15

For us to compare negative fractions, we must know that higher negative fractions are less than the smaller ones

Given the fractions  −5/6 and −13/15

First we will need to write this fractions as percentage:

-5/6 * 100 = -500/6 = -83.3%

-13/15 * 100 = -1300/15 = -86.67%

From both percentages, we can see that -83.3% is greater than -86.67%, hence, −5/6 > −13/15

Answer:

the value of a is 2.

Step-by-step explanation:

3a - 2 + 5a + 3 + 6a + 1 = 30

14a + 2 = 30

14a = 28

a = 2

b.

Step-by-step explanation:

Answer: x=1

Step-by-step explanation: Rearrange the equation by subtracting what is to the right of the equal sign from both sides of the equation :

3*x+2*(5*x-3)-(7)=0

3x + 2 • (5x - 3)) - 7 = 0

Pull out like factors :

13x - 13 = 13 • (x - 1)

13 = 0

A a non-zero constant never equals zero.

Solve : x-1 = 0

Add 1 to both sides of the equation :

x = 1

Answer:

x = -8.4

Step-by-step explanation:

You do the inverse operations:

The inverse of division is multiplication, so:

x/1.2 = -7 (x 1.2) - multiply by 1.2

x = -8.4

Equation: y = 2x + 4

72 = 2x + 4

68 = 2x

x = 34

Hope this helps! :)

Slope of the line: rise/run = 4/2 = 2

y-intercept = 4

Plug into y = mx+b

y = 2x + 4

Plug 72 for y

72 = 2x + 4

=34

Answer:

(3x + 4y)(x + 2y)

Step-by-step explanation:

3x^2+ 10xy + 8y^2

All signs are positive, so we'll only look at positive factors of 3 and 8.

3 factors into 3 and 1.

8 factors into 4 and 2, and it also factors into 8 and 1.

I like to try closer factors in value, so I'll start with 4 and 2 for 8.

Try:

(3x + 2y)(x + 4y) = 3x^2 + 12xy + 2xy + 8y^2 = 3x^2 + 14xy + 8y^2

The middle term does not work. Switch 2y and 4y and try again.

Try:

(3x + 4y)(x + 2y) = 3x^2 + 6xy + 4xy + 8y^2 = 3x^2 + 10xy + 8y^2

It works.

Answer: (3x + 4y)(x + 2y)

Answer:

1 = 137

2 = 43

3 = 43

4 = 137

Step-by-step explanation:

for the first line, do (180-137 = 43)

then, 43 would be corresponding angle to 2 - making them equal

2 would be vertically opposite to 3, making them equal

137 and 1 are corresponding- making them equal

4 is vertically opposite to 1 - making them equal

Answer:

2x^4

Step-by-step explanation:

As the magnitude of x gets larger, the absolute value of x gets large

The higher degree terms are going to grow much faster than the lower degree terms, so that is what we need to focus on

The highest degree terms here in the numerator and denominator are 8x^6 and 4x^2, so let's divide the two, and simplify to get our solution;

f(x) = (8x^6) / (4x^2)

= 2x^6 / x^2 = 2x^(6 - 2)

= 2x^4 (solution)

Answer:

Sebastian did.

Step-by-step explanation:

seb = 94% or 47/50

while frankie = 43/50 or 86%

Also look at 50 if you want and you can see it divides evenly with 100. Basically each mistake you make is 2 percent lost.

Answer: Sebastian

Step-by-step explanation: Divide 43 by 50.

43/50=0.86

tests are graded by the decimal point so he got 86%

since 94% is more than 86% sebastian scored higher

Answer:

7/15

Step-by-step explanation:

2/5 + 1/3 is the same as 2/5 + 5/15.. so we add them together to get 7/15. This can not be simplified further

To know who has gotten most I like to think in percentage terms. 2/5 is the same as 40% (2/5 is the same as 4/10 = 40/100 =40%). 1/3 is 33.33% so Ane got more

Answer:

A. 11/15 B. Ibai.

Step-by-step explanation:

First, find the Least Common Multiple, or LCM, of the denominators, which is 15. Then, multiply each denominator by the number that gets the denominator to 15, which is the LCM. Next, multiply the numerator by the same number you multiplied the denominators, which was 3 for Ibai, and 5 for Ane. Finally, compare the two numbers to see which is higher. In this case, Ibai took out 6/15, while Ane took out 5/15, meaning Ibai took out more than Ane. Also, together, Ibai and Ane both drew out 11/15 together.
