Friona made an error in the second step that is step 2.
What error did she make in writing her step.?The descriptions of each step are given the multiplications of the bionomical and the trinomial i.e (2x – 3)(5x2 – 2x + 7). The titled Fiona's product has the 2 columns and the 5 rows. The first Colum is labeled as with 4 steps The second Colum is labeled as a result and the fifth is expression.
Using the distributive property and multiplying by -3 times each term of the trinomial. Thus, -3(5x^2 - 2x + 7) = -15x^2 + 6x - 21 Fiona written -6x instead of + 6x. This is the error. Hence the answer is "Step 2"

Which weighs more: 16 oz. of soda or a solid pound of gold?
Answer:
Gold weighs more
Step-by-step explanation:
The fact that they both equal 16 oz confirms the fact that gold weighs more. The reason for this is because even if the mass is the same the weight involves the gravitational pull on the earth meaning gold is greater.
1 pound of gold weighs more than 16 ounces of Soda.
We are told that;
Weight of soda = 16 Oz (ounces)
Weight of gold = 1 pound
Now, from conversions between pounds and ounces, 1 pound = 16 oz
Thus means that soda too also has a mass of 1 pound same as Gold.
However, despite the fact that they have the same mass, it doesn't mean they weigh the same because Gold has a gravitational pull which means force of gravity on it from the earth and it means it will weigh more.

You have 24 homework problems for math class. You finish of them during some
extra time in class. If you complete 4 more problems while waiting for the bus, what
fraction of the 24 problems will remain?
دو آدم
8
24
Answer:
Step-by-step explanation:
If you were to complete 4 out of the 24 current homework problems, then I can say that you'd have 5/6 of the problems remaining. This is because 24 divided by 4 is 6, so completing 4 questions counts as completing 1/5 of the total amount of work present. If you want to use whole numbers instead of fractions, you would have completed 4 out of 24 questions and would have 20 remaining

Draw an angle and then draw the opposite ray to one of its sides, to form a linear pair. Find the measure of the angle formed by the angle bisector of the original angle and the opposite ray if the original angle measures 50°, 90°, and 150°. 1. If the angle equals 50°, then the measurement of the required angle is ? 2. If the angle equals 90°, then the measurement of the required angle is ? 3. If the angle equals 150°, then the measurement of the required angle is ?
Answer:
(1)155 degrees
(2)135 degrees
(3)105 degrees
Step-by-step explanation:
Let the original angle [tex]= \theta[/tex]
Angle Bisector of the original angle = [tex]\dfrac{ \theta}{2}[/tex]
If the other angle forms a linear pair, then:
The other angle, [tex]\beta=180^\circ-\theta[/tex]
Therefore, the measure of the angle formed by the angle bisector of the original angle and the opposite ray is:
[tex]\dfrac{ \theta}{2}+180^\circ-\theta\\=180^\circ-\dfrac{ \theta}{2}[/tex]
(1)If the angle equals 50°
Then the measurement of the required angle
[tex]=180^\circ-\dfrac{ 50}{2}\\=180^\circ-25^\circ\\=155^\circ[/tex]
(2)If the angle equals 90°
Then the measurement of the required angle
[tex]=180^\circ-\dfrac{ 90}{2}\\=180^\circ-45^\circ\\=135^\circ[/tex]
{3)If the angle equals 150°
Then the measurement of the required angle
[tex]=180^\circ-\dfrac{ 150}{2}\\=180^\circ-75^\circ\\=105^\circ[/tex]

The value of y when x=7
Answer:
y = 49
Step-by-step explanation:
y ∝ x²
=> y = kx²
Where k is the constant of proportionality
k = 1 (We've found this out in the previous question)
Now,
y = ? when x = 7
The above equation becomes:
=> y = (1)(7)²
=> y = (1)(49)
=> y = 49
A coordinate grid with 2 lines. One line, labeled f(x) passing through (negative 3, 3), (0, 3), and the point (4, 3). The other line is labeled g(x) and passes through (negative 4, negative 3), (0, 0), and the point (4, 3). Which input value produces the same output value for the two functions on the graph? x = −1 x = 0 x = 3 x = 4
Answer:
x = 4
Step-by-step explanation:
It is stated that f(x) passes through
(-3, 3), (0, 3), (4, 3)
and g(x) passes through
(-4, -3), (0, 0), (4, 3)
Therefore, both functions pass through (4, 3). That is, the input value x = 4 produces the same output value y = 3 for the two functions.

About 3% of the population has a particular genetic mutation. 600 people are randomly selected.
Find the standard deviation for the number of people with the genetic mutation in such groups of 600. Round your answer to three decimal places
Answer:
Standard deviation for the number of people with the genetic mutation = 4.178
Step-by-step explanation:
Explanation:-
Given random sample size 'n' =600
proportion of the Population 'p'=3% or 0.03
Let 'X' be the random variable in binomial distribution
Mean of the binomial distribution
μ = n p
= 600 X 0.03
= 18
Mean of the binomial distribution ' μ ' =18
Standard deviation of the binomial distribution
σ = [tex]\sqrt{npq} = \sqrt{600 X 0.03 X 0.97} = \sqrt{17.46} = 4.178[/tex]
Conclusion:-
Standard deviation for the number of people with the genetic mutation = 4.178

-0.612 + (-8) + 18+
-0.612 + 8 - 181
0.612 + (-8) + 181
DONE
Answer:
The additive inverse of the polynomial being subtracted is -0.612-8+181
Step-by-step explanation:
Given expression : (1.32 +0.412 – 241) – (0.612 + 8 - 181)
Now the polynomial being subtracted : (0.612 + 8 - 181)
Additive inverse : The number in the set of real numbers that when added to a given number will give zero.
So, Additive inverse of 0.612 = -0.612
Additive inverse of 8 = -8
Additive inverse of -181 = 181
So, The additive inverse of polynomial being subtracted : -0.612-8+181
So, Option B is true
Hence the additive inverse of the polynomial being subtracted is -0.612-8+181
In 2010, Rafik bought a house. In 2015, Rafik sold the house to Bianca. He made a 20% profit on the sale. In 2019, Bianca sold the house for £193800. She made a 5% loss. Work out how much Rafik paid for the house in 2010.
Answer:
£170000
Step-by-step explanation:
In 2010, Rafik bought a house. Let us assume Rafik bought the house for $x. In 2015, Rafik sold the house to Bianca and made 20% profit. 20% profit = 20% of x = 0.2 × x = 0.2x. Therefore Rafik sold the house to Bianca at x + 0.2x = 1.2x. Bianca bought the house at 1.2x
The house was sold by Bianca at 5% loss in 2019. 5% loss = 0.05(1.2x) = 0.06x
Therefore the house was sold by Bianca at 1.2x - 0.06x = 1.14x. Since Bianca sold the house at £193800.
⇒ 1.14x = 193800
x = 193800/1.14
x = £170000
Rafik paid £170000 for the house in 2010

Answer:
I think that you would divide all the euros by 1.35 to get the pounds
if thats right then the answer should be £2504.07407408
Step-by-step explanation:
i did this by first getting the hotel price (125 euros per night) and timesing that by 14 as they stay for 14 nights, this gives you 1750
then i converted 1750 to pounds by dividing 1750 by 1.35 to get £1296.2962963
next i did the wifi price (6 x 13 = 78, 78 divided by 1.35 = £57.7777777778)
after that i added those two prices together to get £1354.07407408
the final step was to add £1150 so i got £2504.07407408, and that hopefully should be the answer !
hope this works :)

A car is traveling in a straight line at a speed of 55 miles per hour. How fast is the cart
1 minute = 3,600 seconds
1 mile = 5,280 feet
Express the answer to the correct number of significant figures.
The car is _____traveling
feet per second.
Answer:
1.34 feet/seconds
Step-by-step explanation:
Looking at the above question, we would be converting 55 miles per hour to feet per seconds.
From the above question, we are given the following conversion values
1 minute = 3,600 seconds
1 mile = 5,280 feet
55 miles per hour = 55 mile / 1 hour
So,
If 1 mile = 5,280 feet
55 miles = x feet
We cross Multiply
x = 5,280 × 55
x = 290,400 feet
Hence, 55 miles = 290,400 feet
1 hour = 60 minutes
If 1 minute = 3,600 seconds
60 minutes = x seconds
We cross multiply
x = 60 × 3,600
x = 216,000 seconds.
This means
60 minutes = 216,000 seconds
In other to find out how fast is the car is,
Speed = Distance / Time
Speed = 290,400 feet/216,000 seconds
Speed = 1.3444444444 feet/seconds
To the to the correct number of significant figures, the car is traveling at 1.34 feet per second.

Answer:
22.5
Step-by-step explanation:
Since 13.5 is 60% of something, the opposite operation would be to divide 13.5 by 60% (or 0.6). You can check this by finding 60% of 22.5:
13.5 / 0.6 = 22.5
22.5 x 0.6 = 13.5
Answer:
In the problem, 60% of 22.5 is 13.5.
Step-by-step explanation:
The first thing we have to do is know what the problem is asking us to find. In the problem, we are asked to find the number that 13.5 is 60% of. In order to find this number, we have to divide. We are going to divide 13.5 by 60%. 60% can be turned into decimal form which is 0.6.
13.5 ÷ 0.6 = 22.5
So, the number that 13.5 is 60% of is 22.5.

Raj takes a taxi to the airport. He expects the taxi to travel at an average speed of 60 mph. The distance from Raj's house to the airport is 30 miles. If Raj's taxi actually travels at an average speed of 50 mph, how many more minutes does the journey take than expected?
Answer:
6 minutes more
Step-by-step explanation:
Time = Distance ÷ Speed
Time = 30miles ÷ 60mph
Time = 30mins
Time = 30miles ÷ 50mph
Time = 36mins
36mins - 30mins = 6mins difference
Answer: 6 minutes
Step-by-step explanation:
Time = Distance / speed
When speed is 60 mph
Time = 30/60 = 1/2 hour = 30 minutes
When speed is 50 mph
Time = 30/50 = 3/5 hour = 36 minutes
salt water has a density of 1030 kg/m^3. a piece of wood with mass of 1260 g is a cuboid with dimensions 7 cm x 10 cm x 15 cm.Will it float in water? a) Work out the volume of the wood b) Work out the density of the wood
Answer:
No, the piece of Wood will not follow.
a) Volume = 0.00105 m³
b) Density of Wood = 1200 kg/m³
Step-by-step explanation:
For the piece of wood to float on salt water, the density of the wood should be less than 1030kg/m³
First we'll calculate the volume of the piece of wood, which later we'll use to find the density.
a) Volume of WoodVolume is given by 7 cm × 10 cm × 15 cm
Convert all the values into meters.
7 cm = 7/100 = 0.07 m
10 cm = 10/100 = 0.10 m
15 cm = 15/100 = 0.15 m
Calculate Volume:
Volume = 0.07 m × 0.1 m × 0.15 m
Volume = 0.00105 m³
b) Density of Wood
Formula for density is given by
Density = Mass / Volume
Where
Volume = 0.00105 m³
Mass = 1260 g = 1260/100 = 1.260 kg
Density = 1.260 kg/0.00105 m³
Density of Wood = 1200 kg/m³
As Density of Wood ≥ Density of Salt water , the piece of Wood will not float.
