Answer:

  5.806 × 10³

Step-by-step explanation:

Put a decimal point to the right of the left-most digit: 5.806. Now multiply by the place value of that digit.

  5.806 × 10³

___

The 5 is in the "thousands" place. Of course a "thousand" is 1000 = 10·10·10 = 10³. The place value multiplier (1000 or 10³) is written using the exponent when we write scientific notation.

Step-by-step explanation:

3(x+1)=-2(x-1)-4

3x+3=-2x+2-4

by combining like terms on one side and unlike term by other side

3x+2x=2-4-3

5x= -5

x= -5/5

x=-1

Step-by-step explanation:

8√5 + √250 - √720

= 8√5 + (√2)(√5)(√25) - (√5)(√144)

= 8√5 + 5(√2)(√5) - 12√5

= √5 (8 + 5√2 - 12)

= √5 (5√2 - 4)

= √10 (5 - √2).

Answer:£11,854.11

Step-by-step explanation:

Answer:

find b: since the triangle is right angle triangle apply the Pythagorean theorem

c²+b²=d²

b²=d²-c²

b²=16²-12²

b²=256-144

b²=112

the sum of the angle of the triangle=180

( in top Δ abd ) sin Ф=opp/hyp

sinФ=b/d=4√7/16= √7/4  radian

convert to degrees : √7/4 *180/π= 37.91 almost 38 degrees

find a=?? apply law of cosine

a²= d^2 + c^2 − 2dc cosA

a²=16² + 12²-2(16)(12)cos38

a =√(16² + 12²-2(16)(12)cos38)

Answer:

[tex]x=\frac{s}{q+r}[/tex]

Step-by-step explanation:

1 Factor out the common term x

[tex]x(q+r)=s[/tex]

2 Divide both sides by q+r

[tex]x=\frac{s}{q+r}[/tex]

Answer:

Deductive reasoning

Step-by-step explanation:

Deductive reasoning is when you make a conclusion based on facts you previously know. These conclusions are correct.

Inductive reasoning is when you use a previously known fact to come up with a general assumption.

Here, we took some previously known facts (If anyone takes vitamins, they will feel better) and made a conclusion that relates fully to that fact. Since Bob took vitamins, he will feel better.

Answer:

-24 a^2 b^7

Step-by-step explanation:

Simplify the following:

-8×3 a^2 b^4 b^3

Hint: | Combine products of like terms.

3 a^2 b^4 (-8) b^3 = 3 a^2 b^(4 + 3) (-8):

-8×3 a^2 b^(4 + 3)

Hint: | Evaluate 4 + 3.

4 + 3 = 7:

-8×3 a^2 b^7

Hint: | Multiply 3 and -8 together.

3 (-8) = -24:

Answer: -24 a^2 b^7

Answer:

The correct answer is:

Answer:

False

Step-by-step explanation:

1/3^4=3^4

0.012346≠81

False

Answer:

True

Step-by-step explanation:

The negative power property of exponents says that:

[tex]x^{-n}=\frac{1}{x^n}[/tex]

And vice versa:

[tex]\frac{1}{x^{-n}}=x^n[/tex]

Therefore, since our exponent is negative, we can change it to positive if we put it in the numerator. In other words:

[tex]\frac{1}{3^{-4}}=3^4[/tex]

The statement is true.

Answer:

5/6 and 75 1/3%

Step-by-step explanation:

8 1/3 = 25/3

25/3 pages of a book in 10 minutes

Multiply both numbers by the reciprocal of 10, which is 1/10

25/3 x 1/10 = 25/30 = 5/6

So, Charlotte reads 5/6 pages of a book in 1 minute.

Which is equal to 75 1/3%

Answer:

400 feet.

Explanation:

We need to find the difference between the lowest point of Galilee and the lowest point of Death Valley. We can find this by subtracting the lowest point of Galilee by the lowest point of Death Valley. It says the lowest point of Galilee is 682 feet below sea level and the lowest point of Death Valley is 282 feet below sea level. Therefore, we subtract 682 - 282, which equals 400.

Answer:

x≤ 5

Step-by-step explanation:

18-2-1=15

15/3=5

Answer:

the number of book she can carry is 5 books

Step-by-step explanation:

backpack capacity = 18 lb

backpack can carry:

lunch = 1 lb

gym clothes = 2 lb

books = 3 lb per book

find:

how many books can she carry in her backpack?

backpack capacity = lunch + gym clothes +  x books

let x be the number of books

18 = 1 + 2 + 3x

18 - 1 - 2 = 3x

15 = 3x

x = 15 / 3

x = 5

therefore, the number of book she can carry is 5 books
