Please answer for a and b
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.
may someone please help me with this im confused

Rectangle A measures 9 in by 3 in rectangle b is a scaled copy of rectangle A select all of the measurent paris that could be the dimesnions of rectangle b
Answer:
the options are missing, so I looked for a similar question:
4 inches by 3 inches3 inches by 1 inch6 inches by 2 inches
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.

The highest elevation in a small country occurs on a mountain 1232 meters above sea level, while the lowest elevation in the same country occurs at -27 meters (below sea level). What is the difference in elevation between the highest and lowest points?
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 (-) × (-) = +
Kara earned $136.75 last week working 16 hours. She earned $10.50 per hour at the fast food restaurant and $4.25 per hour helping her aunt clean her store. how many hours did she work at the fast food restaurant ? how many hours did she help her aunt clean the store ?
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.
A cement path consists of six equal-sized cement squares arranged in a row to form a rectangle. If the total area of the path is 96 square feet, what is the length in feet of the path?
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.
1) IF DE = 9, find BC
2) if m<ADE = 80, then find m< ABC
3) If DE = 2x + 7 , and BC = 7x - 1, find BC
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

Un aljibe de 12.4 m de profundidad se encuentra totalmente lleno de agua. ¿Cual es la presión en el fundo debido únicamente al peso del agua? Si sabemos que la presión atmosférica total es de 75 cm de hg en el SI ¿Cual es la presión total en el fondo de la piscina?
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.

Step-by-step explanation:
Nicholas wanted to save money to buy his girlfriend a ring. He can save $15 a week and needs at least $200 for the ring he wants to buy. If he starts with
$50 already, will he have enough for the ring within 10 weeks?
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 :)
