If you randomly select a card from a well-shuffled standard deck of 52 cards, what is the probability that the card you select is not a 4? (Your answer must be in the form of a reduced fraction.)
Answer:
12/13
Step-by-step explanation:
A standard deck of cards has four suites
Total number of cards = 52
Total number of cards which are 4 is = 4
The probability that the card selected is 4 = 4/52 = 1/13
S, the probability that the selected card is not a 4 = 1 - (1/13 )= 12/13

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 :)

d
Domain is 0, Range is 450
Answer:
Given the formula for a function, determine the domain and range.
Exclude from the domain any input values that result in division by zero.
Exclude from the domain any input values that have nonreal (or undefined) number outputs.
Use the valid input values to determine the range of the output values.

A cyclist rides her bike at a speed of 9 kilometers per hour. What is this speed in kilometers per minute? How many kilometers will the cyclist travel in 10 minutes? Do not round your answers.
Answer:
per minute: 0.15 km
in 10 minutes: 1.5
Step-by-step explanation:
there are 60 minutes in an hour. we need to find the constant rate of change (is that the name sorry). so 9/60 is 0.15. now we know she goes 0.15 km per minute. then do 10 times 0.15 since 10 minutes. you get 1.5. now we know.
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.

Ben is going to make 1/4 pound burgers for a barbecue next weekend. He is planning on making 19 burgers. How much hamburger meat will he need to make 19 quarter pound burgers?
Answer:
4.75 pounds of hamburger meat
Step-by-step explanation:
In order to calculate the total amount of hamburger meat that Ben would need we would need to multiply the total number of burgers that he wants to make (19) by the amount of meat each burger will use (1/4 pound or 0.25 pound). Therefore, we would do the following...
19 * 0.25 = 4.75 pounds
Finally, we can see that Ben would need a total of 4.75 pounds of hamburger meat to make 19 equal sized 1/4 pound burgers.
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.
A recipe calls for 1 1/2 cups of flour to make 1/4 of a batch of cookies.
How much flour would be needed to make an entire batch of cookies?
A. 2 cups
B. 4 cups
C. 6 cups
D. 8 cups
6 cups of flour would be needed to make an entire batch of cookies.
Given that,
A recipe calls for 1 1/2 cups of flour to make 1/4 of a batch of cookies.
To determines the number of cups of flour that would be needed to make an entire batch of cookies.
What is arithmetic?In mathematics, it deals with numbers of operations according to the statements. There are four major arithmetic operators, addition, subtraction, multiplication and division,
Here,
1 1/2 cups of flour => 1/4 batch of cookies
3/2 cups of flour => 1 / 4 batch of cookies
Multiply by both sides,
4 * 3 / 2 cups of flour => 4 * 1 / 4 batch of cookies
6 cups of flour => 1 batch of cookies
Thus, 6 cups of flour would be needed to make an entire batch of cookies.

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

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.
