Convert the rate to a unit rate. What is 124 feet walked in 10 seconds equal per second?
Answer:
12.4 feet per second
Step-by-step explanation:
Walking 124 feet in 10 seconds is the fraction [tex]\frac{124 feet}{10 seconds}[/tex] this is the same as [tex](\frac{124}{10}) \frac{feet}{seconds}[/tex] We get a decimal by dividing 10 into 124 [tex](12.4)\frac{feet}{seconds}[/tex] That's 12.4 feet per secondWhich one is bigger 1 3/5 or 1.9
Answer:

Step-by-step explanation:
1 3/5 is the same as 1.6. So, which ones bigger? 1.9.
a proportion question
Answer:
because x,y,z are in continuous proportion
=> x/y = y/z
<=> xz = y² =>
[tex]\frac{xz}{y} =y\\\\=>\frac{x^{3}z^{3} }{y^{3} }=y^{3}[/tex](1)
with (1), we have:

Step-by-step explanation:
5 roommates share the cost of an apartment: rent,electricity, and gas. rent costs 1800 and gas costs 150 per month. each roommate pays 425 per month. how much is the electricity bill
Answer:
Electricity bill is 175
Step-by-step explanation:
Given
[tex]Rent = 1800[/tex]
[tex]Gas = 150[/tex]
[tex]Each\ Roommate = 425[/tex] monthly
[tex]Number\ of\ Roommate = 5[/tex]
Required
Determine the electricity bill
If each roommate pays 425, then 5 roommates pay 5 * 425
[tex]Total = 5 * 425[/tex]
[tex]Total = 2125[/tex]
This implies that: the monthly cost of room, gas and electricity add up to 2125.
In other words,
[tex]Gas + Rent + Electricity = 2125[/tex]
[tex]150 + 1800+ Electricity = 2125[/tex]
[tex]1950+ Electricity = 2125[/tex]
[tex]Electricity = 2125 - 1950[/tex]
[tex]Electricity = 175[/tex]
Hence, the electricity bill is 175
Un ingeniero realiza las siguientes observaciones sobre las ventas de impresoras en una tienda: Hay impresoras Epson, Hp y Cannon. El número de impresoras Epson y HP es cinco veces el número de las Cannon. Además, el número de impresoras Epson es el triple que el de la Cannon y El total de impresoras Cannon y Hp asciende a 123
Answer:
En la tienda hay 123 impresoras Epson, 82 impresoras HP y 41 impresoras Cannon.
Step-by-step explanation:
Para determinar el número de impresoras de cada marca, se deben plantear las siguientes ecuaciones:
E + HP = 5 x C
E = 3 x C
C + HP = 123
Así, teniendo en cuenta estas ecuaciones y los valores de cada marca dentro del stock de la tienda, se puede plantear la siguiente equivalencia:
Si E = 3C y E + HP = 5C, entonces HP = 2C, ya que 5C - 3C = 2C.
Entonces, las equivalencias son las siguientes:
E = 3C
HP = 2C
Si C + HP = 123, podríamos decir que 3C = 123. Por ello, dado que 123 / 3 es igual a 41, el número de impresoras Cannon asciende a 41 unidades.
A su vez, el número de impresoras HP es de 82 unidades (41 x 2), mientras que el número de impresoras Epson asciende a 123 unidades (41 x 3).

Step-by-step explanation:
An electronics store has a clearance sale
whereby everything in store is marked down
by 20% of the original price. Jay buys a
Bluetooth speaker with an original price of
R950.00. When he gets to the till, the cashier
lets him know that the speaker is marked
down a further 8% on the reduced price.
i. How much will Jay pay for the speaker?
ii. What is the final discount percentage Jay
gets off the original price?
Answer:
i. R699. 2
ii. 26.4%
Step-by-step explanation:
Given the following data;
First discount (on original price) = 20%
Second discount (on reduced price) = 8%
Original price = R950.00
*To find how much Jay will pay*
First discount;
[tex] Discount = \frac {20}{100} * 950[/tex]
[tex] Discount = 0.2 * 950[/tex]
Discount = R190.00
Reduced price = 950 - 190
Reduced price = R760.00
Second discount;
[tex] Discount = \frac {8}{100} * 760[/tex]
[tex] Discount = 0.08 * 760[/tex]
Discount = R60.8
Selling price = 760 - 60.8
Selling price = R699.2
Therefore, Jay will pay R699.2 for the speaker.
ii. To find the final discount percentage;
[tex] Percent \; discount = \frac {original \;price - selling \; price}{original price} * 100[/tex]
Substituting into the equation, we have;
[tex] Percent \; discount = \frac {950 - 699.2}{950} * 100[/tex]
[tex] Percent \; discount = \frac {250.8}{950} * 100[/tex]
[tex] Percent \; discount = 0.264* 100[/tex]
Percent discount = 26.4%
Therefore, the final discount percentage Jay gets off the original price is 26.4%.
A right cylinder-shaped water tank is used to supply water to a reservoir. If the cylinder has a diameter of 16 feet and a height of 22 feet, what is a reasonable estimate of the maximum amount of water the tank can hold? (Use π≈3.14)
9514 1404 393
Answer:
4421 cubic feet
Step-by-step explanation:
The volume of a cylinder is given by ...
V = πr²h
where r is the radius (half the diameter), and h is the height.
Using your numbers, the cylinder volume is ...
V = (3.14)(8 ft)²(22 ft) ≈ 4421.12 ft³
The maximum amount of water the tank can hold is about 4421 cubic feet.

A die is rolled 5 times. What is the probability that 1 occurs twice, 2, 3 and 4 occur once each, and 5 and 6 do not occur (round off to fourth decimal place)
Answer:
0.0077
Step-by-step explanation:
From the given information;
Each outcome possesses the same probability of 1/6 in a single roll.
The required probability can be estimated by using the multinomial distribution;
Therefore;
[tex]P = \dfrac{5!}{2!\times 1!\times 1!\times\times 1! }\times (\dfrac{1}{6})^2\times (\dfrac{1}{6})\times (\dfrac{1}{6})\times (\dfrac{1}{6})[/tex]
[tex]P = 60\times (\dfrac{1}{36})\times\dfrac{1}{216}[/tex]
P = 0.0077
The required probability = 0.0077 to 4 decimal decimals

Winston deposited $3,294 in a bank account with an annual interest rate of 2.6%. How much interest was earned in 5
years? Round your answer to two decimal places.
Answer:
FV= $3,725.07
Step-by-step explanation:
Giving the following information:
Initial investment (PV)= $3,294
Number of periods (n)= 5 years
Interest rate (i)= 2.6% = 0.026
To calculate the future value (FV), we need to use the following formula:
FV= PV*(1+i)^n
FV= 3,294*(1.026^5)
FV= $3,725.07

Answer:
Part 1: y=2x-12
Part 2: 12=2x-y
Step-by-step explanation:
Given Information:
m (slope) = 2
There is a point: (5, -2)
PART 1
Solution: Use the formula: [tex]y=m(x-x_{1} )+y_{1}[/tex]
y=2(x-(5))+(-2)
y=2x-10-2
y=2x-12
PART 2
y=2x-12 (from part 1)
0=2x-y-12
12=2x-y

The diameter of a pipe is normally distributed, with a mean of 0.4 inch and a variance of 0.0009. What is the probability that the diameter of a randomly selected pipe will exceed 0.418 inch
Answer:
P(X > 0.418) = 0.27425
Step-by-step explanation:
We are given;
Population mean; μ = 0.4 inch
Variance; Var = 0.0009
Sample mean; x¯ = 0.418
First of all let's get the standard deviation which is;
σ = √Var
σ = √0.0009
σ = 0.03
Now, z - score formula is;
z = (x¯ - μ)/σ
z = (0.418 - 0.4)/0.03
z = 0.6
We want to find the probability that the diameter of a randomly selected pipe will exceed 0.418 inch. Thus;
P(X > 0.418) = 1 - P(X ≤ 0.418)
From z-distribution table attached, P(X ≤ 0.418) = P(Z) = 0.72575
Thus;
P(X > 0.418) = 1 - 0.72575
P(X > 0.418) = 0.27425
A Normal distribution has mean µ = 61.6. Find it’s standard deviation if 20% of the values are greater than 70. (Hint--use the z-score formula).
Answer:
The value is [tex]\sigma = 9.976[/tex]
Step-by-step explanation:
From the question we are told that
The mean is [tex]\mu = 61.6[/tex]
Given that 20% of the values are greater than 70, the z-score to the right of the curve corresponding to 20% (0.2) of the values is
[tex]z-score = 0.842[/tex]
Generally this z-score is mathematically represented as
[tex]z-score = \frac{x - \mu }{\sigma }[/tex]
Here x = 70
So
[tex]0.842 = \frac{70 - 61.6 }{\sigma }[/tex]
=> [tex]\sigma = 9.976[/tex]

1. what is the difference when (t-3v) is subtracted from the sum of (7t-2u-3v) and (3t+5u-8v)?
2. Which of the following best describes “The movement of a lift is positive 2 levels”? *
3. How many like terms are there in the expression 2x + 3y - 5x + yz - x?
Answer and Step-by-step explanation:
*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^*^
1. Let's write out the equation to subtract.
7t - 2u - 3v - (t - 3v)
Distribute the negative to the t and -3v.
7t - 2u - 3v - t + 3v (The negatives cancel out)
Now simplify by combining like terms.
6t - 2u
This is the answer because the 3v and -3v cancel out.
2. I don't really understand what this is saying. Is there answer choices for this? But what I think its saying is that the lift has a constant of 2.
3. To find out the amount of terms, we would simplify the equation.
2x + 3y - 5x + yz - x
-4x + 3y + yx
Here, we can see that we have 3 terms in this expression.
-4x is the first term, +3y is the second term, and +yx is the third term.
