Answer:

The answer is 2.077  ×  10 ^-4

Step-by-step explanation:

Move the decimal so there is one non-zero digit to the left of the decimal point. The number of decimal places you move will be the exponent on the  10 . If the decimal is being moved to the right, the exponent will be negative. If the decimal is being moved to the left, the exponent will be positive.

Hope this helps!

Subract 5 5/21 from 13 1/7
Sladkaya [172]

Answer:

The answer is 166/21, or 7 19/21

Step-by-step explanation:

First, you would set up the equation, which is:

13 1/7 - 5 5/21

Next, you would turn them into an improper fraction, which is:

92/7 - 110/21

Then, you would multiply 92/7 by 3/3 because that is the least common multiple for 21 and 7 (which are the denominators). When you are done multiplying, the equation would be:

276/21 - 110/21

Afterwards, you would subtract the numerators and leave the denominators alone, which gives you the answer 166/21. As a mixed number, this would equal 7 19/21.

Let x be the number of treats bought
Let y be the pounds of food bought

25= 2y+x

Given that she has buys 9 pounds of dog food:

25= 2(9)+x
25=18 +x

Answer:

<h3>Some Points about this Formula :- </h3>

  • The formula given here is the definition of the derivative in calculus. The derivative measures the rate at which a quantity is changing.

  • For example, we can think of velocity, or speed, as being the derivative of position - if you are walking at 3 miles (4.8 km) per hour, then every hour, you have changed your position by 3 miles.

<h3>To know the solution,Refer to the above attachment . </h3>

The coordinates of the endpoints of ST are (-2,3) and (3, y) respectively supposethe distance between s and t us 13 units.What v
igor_vitrenko [27]

Answer:

The values of y would be -9 and 15

Step-by-step explanation:

we know that

the formula to calculate the distance between two points is equal to

d=\sqrt{(y2-y1)^{2}+(x2-x1)^{2}}

we have

d=13\ units

S(-2,3) and T(3,y)

substitute the given values in the formula and solve for y

13=\sqrt{(y-3)^{2}+(3+2)^{2}}

13=\sqrt{(y-3)^{2}+25}

squared both sides

169=(y-3)^{2}+25

(y-3)^{2}=169-25

(y-3)^{2}=144

take square root both sides

y-3=(+/-)12

y=3(+/-)12

y=3(+)12=15

y=3(-)12=-9

therefore

The values of y would be -9 and 15
