Answer:

a

Step-by-step explanation:

a

Answer:

Step-by-step explanation:

a can't be an integer

8/√2 doesn't reduce to an integer. It will give you 4*√2 * √2/√2 = 4√2

-√18/√2 = -√(3*3*2)/√2 = -3(√2)/√2 = -3

At best you will get 4√2 - 3

a = 4√2

b = - 3

Edit

b is correct. the answer for b = -3

a  can't be done giving an integer answer. My best guess is 4 but that is not the correct answer.  You could write it as (4 - 3)√2

My advice to you is to present it to your instructor and see what he/she comes up with.

Answer:

Yes, he will have enough in 10 weeks

Step-by-step explanation:

1 - Set up an equality statement to prove

He starts with 50, and earns 15 per week to earn more than 200.

Therefore,

50 + 15 per week for 10 weeks must be greater than or equal to 200

or

50 + 15x ≥ 200

2 - "Plug and chug" to solve

50 + 15x ≥ 200

50 + 15(10) ≥ 200

50 + 150 ≥ 200

200 ≥ 200

3 - Prove

Is 200 greater than equal to 200? Yes its equal thus this statement is valid which means he will have enough in 10 weeks

Hope this helps :)

Answer:

ANSWER: she worked 11 hours at the fast food restaurant and 5 hours helping her aunt

Step-by-step explanation:

First we are going to try to find how many hours she worked on the fast food restaurant so you multiply 4.25 time 16 and x

10.50x + 4.25(16-x) =136.75

10.50x + 68 - 4.25x= 136.75

Then, you subtract 68 from both sides and subtract 4.25x from 10.50x

6.25x=68.75

Divide

X=11 that is how many hours she worked at the FAST FOOD RESTAURANT

Then 16-11 and that gives us how many hours she helped her aunt.

Answer: 1259 meters

Step-by-step explanation:

Highest elevation = 1232 meters

Lowest elevation = -27 meters

The difference in elevation between the highest and lowest points will be:

= 1232 - (-27)

= 1232 + 27

= 1259 meters

Note that (-) × (-) = +

Answer:

24 feet

Step-by-step explanation:

Given that:

The length of the rectangle is 6 times the side of a cement square.

Now, this rectangle is formed from 6 squares;

The total area of the path of this square = 96 square feet;

The area of each square now = 96/6 = 16 square feet

Recall that:

Area of a square = S²

where S is the side length

16 = S²

S = [tex]\sqrt{16}[/tex]

S = 4 ft

The length of the path in feet now is: L × w

= 6 × 4

= 24 feet.

Answer:

a) p = 121644 Pa

b) [tex] p_{T} = 221644 Pa [/tex]  

Step-by-step explanation:

a) La presión en el fondo debido únicamente al peso del agua se puede calcular usando la siguiente ecuación:

[tex] p = \rho gh [/tex]

En donde:

ρ: es la densidad del agua = 1000 kg/m³

g: es la gravedad = 9.81 m/s²

h: es la profundidad = 12.4 m

[tex] p = \rho gh = 1000 kg/m^{3}*9.81 m/s^{2}*12.4 m = 121644 Pa [/tex]

Entonces, la presión en el fondo debido al agua es 121644 Pa.

b) Para hallar la presión total en el fondo debemos ahora considerar la presión atmosférica:

[tex] p_{T} = p_{0} + \rho gh [/tex]  

En donde p₀ es la presión atomsférica = 75 cmHg

[tex] p_{T} = 750 mmHg\frac{1 Pa}{0.0075 mmHg} + 121644 Pa = 221644 Pa [/tex]

Por lo tanto, la presión total en el fondo es 221644 Pa.

Answer:

(6/11, 16/11)

Step-by-step explanation:

While it's fairly obvious that you're supposed to "solve this system of equations," it'd be clearer if you were to say so specifically.  Also, reduce ambiguity by using parenthes:  You meant either (5/3)x or 5/(3x).  Which one?  I'm assuming it's (5/3)x.

Then our system is:

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

      x  +  y =  2

Let's eliminate y through addition/subtraction.  Multiply the 2nd equation through by +2:

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

     2x  + 2y = 4

------------------------

(11/3)x       =  2

Multiplying both sides by 3 eliminates the fractional coefficient:

11x = 6

Then x = 6/11.  Now we must solve for y:

-(6/11) + y = 2

Multiplying 2 by 11/11 yields:

-(6/11) + y = 22/11.

This simplifies to y = 16/11

Thus, the solution of this system is

(6/11, 16/11)

Answer:

1. BC = 18

2. m<ABC = 80°

3. x = 5

Step-by-step explanation:

1. If DE = 9, therefore:

[tex] BC = 2 \times 9 = 18 [/tex] (based on the midsegment theorem, DE is half the length of the third side, BC)

2. m<ADE = 80°, then,

m<ABC = 80°

This is because m<ADC and m<ABC are corresponding angles. Corresponding angles are congruent.

3. DE = 2x + 7 , and BC = 7x - 1, find BC

Thus:

[tex] BC = 2 \times DE [/tex] (midsegment theorem)

[tex] 7x - 1 = 2 \times (2x + 7) [/tex] (substitution)

Solve for x

[tex] 7x - 1 = 4x + 14 [/tex]

Collect like terms

[tex] 7x - 4x = 1 + 14 [/tex]

[tex] 3x = 15 [/tex]

Divide both sides by 3

x = 5

Answer:

A. -3 < x < 1

General Formulas and Concepts:

Step-by-step explanation:

"When is the function decreasing" is saying when the graph is going down.

Calculus-wise, we are finding when the slope of the tangent line is negative.

From the graph, we see it decreasing from -3 to 1. Everywhere else is increasing.

Therefore, our interval decreasing is from (-3, 1).

Answer:

the options are missing, so I looked for a similar question:

the correct options are:

3 inches by 1 inch

6 inches by 2 inches

A scaled copy means that the values of rectangle A are related to the value of rectangle B by a scaling factor. In this case, the scaling factor is 3:1. This means that for every 3 inches in rectangle A, you will have 1 inch in rectangle B.

E.g. imagine that instead of making the rectangle smaller, you would make it larger. Using the same scale 3:1, rectangle B could be 30 inches by 10 inches, or 600 inches by 200 inches.
