Complete question:

<em>The leatherback sea turtle is the fastest known reptile, with a maximum speed of 21.92 miles per hour (mph). </em>

<em>Which of the following equations, where d is distance in miles and t is time in hours, represents a speed that is less than that of the leatherback sea turtle? </em>

<em> </em>

<em>Select all that apply. </em>

<em>a.</em><em> d = 2.192t </em>

<em>b.</em><em> d = 20t </em>

<em>c.</em><em> d = 22t </em>

<em>d.</em><em> d = 30t</em>

<em />

Answer:

<em>a (2.192t) and b (20t)</em>

<em />

Step-by-step explanation:

Since units for distance and time are all measured in miles and hours respectively, we can simply compare the values of the options given with the leatherback turtle speed and express if the value is lower or not. We must pay special attention to the decimal separator in some cases.

<em />

<em>Leatherback sea turtle: </em><em>d = 21.92t</em>

<em>a.</em><em> d = 2.192t  </em><em>is less </em><em>than 21.92t</em>

<em>b.</em><em> d = 20t  </em><em>is less </em><em>than 21.92t</em>

<em>c.</em><em> d = 22t  </em><em>is more </em><em>than 21.92t   </em>

<em>d.</em><em> d = 30t </em><em>is more </em><em>than 21.92t</em>

inna [77]
3x+4y=5
2x+3y=

-2(3x+4y)=5(-2)
3(2x+3y)=4(3)

-6x-8y=(-10)
6x+9y=12

Add the equations

-6x-8y=(-10)
+ 6x+9y=12
-----------------
0x+y=2
y=2

Substitue y into an equation

6x+9(2)=12
6x+18=12
6x=-6

Calculate the value for each determinant:
Dafna1 [17]

Answer:

See explanations below

Step-by-step explanation:

Example of how to find the determinant of a 2×2 matrices is as shown;

\left[\begin{array}{ccc}a&b\\c&d&\end{array}\right]

= (a*d)-(b*c)

= ad - bc

Applying this to solve the given questions

1) (3*4) - (-3*-1)

= 12 - (3)

= 9

2) (-12*5)-(-1*12)

= -60 - (-12)

= -60+12

= -48

3) (0*4)-(-1*17)

= 0-(-17)

= 0+17

= 17

4) (8*-1)-(-4*-1)

= -8-(4)

= -8-4

= -12

5) (2*-1)-(2*-1)

= -2-(-2)

= -2+2

= 0

6) 1(1) - 0(0)

= 1 - 0

= 1

Geralds baby brother spends 7/8 ofhis day sleeping. How many hours does his baby brother sleep
Effectus [21]
His baby brother sleeps 21 hours.
There's a total of 24 hours in a day so you can divide by 8. That means 1/8 of the day is equal to 3 hours, so 7 times 3 hours equals 21 hours
