8 divided by 1 4/5 in either fraction form or just number
Answer:
4.44444444444 or 40/9
Step-by-step explanation:
i searched it up
8 divided by 1 4/5 in fraction form will be 40 / 9. Then the faction number 40 / 9 in the decimal form will be 4.4444.
What is Algebra?The analysis of mathematical representations is algebra, and the handling of those symbols is logic.
A fraction number is a number that represents the part of the whole, where the whole can be any number. It is in the form of numerator and denominator.
The mixed fraction number is converted into a faction number.
⇒ 1 4/5
⇒ 1 + 4/5
⇒ (5 + 4) / 5
⇒ 9/5
Then the quotient of the numbers 8 and 9/5 will be given as,
⇒ 8 / (9/5)
⇒ 8 x 5 / 9
⇒ 40 / 9
The faction number 40 / 9 in the decimal form will be 4.4444.

A bouncy ball is dropped such that the height of its first bounce is 6 feet and each successive bounce is 72% of the previous bounce's height. What would be the height of the 6th bounce of the ball? Round to the nearest tenth (if necessary).
Answer:1.2
Step-by-step explanation:
The height of the 6th bounce of the ball will be 1.2 feet.
What is geometric sequence?
A geometric sequence is a sequence in which each term is found by multiplying the preceding term by the same value.
What is the formula for finding the nth term of geometric sequence?The nth term of the geometric sequence is given by
[tex]T_{n} =ar^{n-1}[/tex]
Where,
[tex]T_{n}[/tex] is the nth term.
r is the common ratio
a is the first term
According to the given question.
During the first bounce, height of the ball from the ground, a = 6 feet
And, the each successive bounce is 72% of the previous bounce's height.
So,
During the second bounce, the height of ball from the ground
= 72% of 6
= [tex]\frac{72}{100} (6)[/tex]
= 0.72 × 6
= 4.32 feet
During the third bounce, the height of ball from the ground
= 72% of 4.32
= [tex]\frac{72}{100} (4.32)[/tex]
= 3.11 feet
Like this we will obtain a geometric sequence 6, 4.32, 3.11, 2.23,...
And the common ratio of the geometric sequence is 0.72
Therefore,
The sixth term of the geometric sequence is given by
[tex]T_{6} = 6(0.72)^{6-1}[/tex]
[tex]T_{6} =6(0.72)^{5}[/tex]
[tex]T_{6} = 6 (0.193)[/tex]
[tex]T_{6} = 1.16 feet[/tex]
[tex]T_{6} = 1.2[/tex] feet
Hence, the height of the 6th bounce of the ball will be 1.2 feet.

Greg has a 15 foot ladder. He needed to clean his gutters which are 12 feet high from the ground. How far away does Greg need to place the ladder from the base of the house to reach the gutters
Answer:
Base = 81 feet
Step-by-step explanation:
Given that,
Length of the ladder = 15 foot
Greg needed to clean his gutters which are 12 feet high from the ground.
We need to find how far away does Greg need to place the ladder from the base of the house to reach the gutters. Let it is b.
Here, hypotenuse = 15 feet, height = 12 feet and base = b
We can use Pythagoras theorem to find b.
[tex]b^2+h^2=H^2\\\\b^2=H^2-h^2\\\\b^2=15^2-12^2\\\\b^2=225-144\\\\b=81\ \text{feet}[/tex]
So, the ladder should be placed at a distance of 81 feet from the base of the house to reach the gutters.

What is obtuse triangle?"It is a triangle whose one of the angles measure greater than 90° and other two acute angles."
What is law of sines?"The ratio of the length of a side of a triangle to the sine of the angle opposite to that side is the same for all sides and angles in a given triangle."
For given question,
We have been given an obtuse triangle ABC.
Here, ∠B = 32°
∠C = 125°
We know that the sum of all angles of a triangle is 180°
⇒ ∠A + ∠B + ∠C = 180°
⇒ ∠A + 32° + 125° =180°
⇒ ∠A = 23°
Using the law of sines to triangle ABC,
[tex]\Rightarrow \frac{a}{sinA} =\frac{b}{sinB} =\frac{c}{sinC} \\\\\Rightarrow \frac{7}{sin23^{\circ}} =\frac{b}{sin32^{\circ}} =\frac{c}{sin125^{\circ}}[/tex]
Consider,
[tex]\Rightarrow \frac{7}{sin23^{\circ}} =\frac{b}{sin32^{\circ}} \\\\\Rightarrow \frac{7}{0.39} =\frac{b}{0.53} \\\\\Rightarrow 7\times 0.53=b\times 0.39\\\\\Rightarrow b = 9.5[/tex]
Now we find the length of the side AB.
[tex]\Rightarrow \frac{7}{sin23^{\circ}} =\frac{c}{sin125^{\circ}} \\\\\Rightarrow \frac{7}{0.39} =\frac{c}{0.82} \\\\\Rightarrow 7\times 0.82=c\times 0.39\\\\\Rightarrow c = 14.72[/tex]
Therefore, the missing values are:
A = 23°
b = 9.5
c = 14.72

Let X, denote the weight of a randomly selected prepackaged one-pound bag of carrots. Of course, one pound bags of carrots won't weigh exactly one pound. In fact, history suggests that Xi is normally distributed with a mean of 1.18 pounds and a standard deviation of 0.07 pound. Now, let W denote the weight of randomly selected prepackaged three-pound bag of carrots. Three pound bags of carrots won't weigh exactly three pounds either. In fact, history suggests that Wis normally distributed with a mean of 3.22 pounds and a standard deviation of 0.09 pound. Selecting bags at random, what is the probability that the sum of three one-pound bags exceeds the weight of one three-pound bag?
Answer:
0.9830 = 98.30% probability that the sum of three one-pound bags exceeds the weight of one three-pound bag
Step-by-step explanation:
When the distribution is normal, we use the z-score formula.
In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.
Three one pound bags:
3 one pound mags, which have mean 1.18 and standard deviation of 0.07. The mean is 1.18 multiplied by 3, and the standard deviation will be 0.07 multiplied by the square root of 3. So
[tex]\mu_{1} = 3*1.18 = 3.54[/tex]
[tex]\sigma_{1} = 0.07\sqrt{3} = 0.1212[/tex]
Three pound bags:
Mean 3.22, standard deviation 0.09. So
[tex]\mu_{2} = 3.22, \sigma_{2} = 0.09[/tex]
What is the probability that the sum of three one-pound bags exceeds the weight of one three-pound bag?
Here, we work with the subtraction of the normal variables. The mean is the subtraction of the means, and the standard deviation is the square root of the sum of the variances. So
[tex]\mu = \mu_{1} - \mu_{2} = 3.54 - 3.22 = 0.32[/tex]
[tex]\sigma = \sqrt{\sigma_{1}^2 + \sigma_{2}^2} = \sqrt{0.1212^2+0.09^2} = 0.151[/tex]
This is the probability of the subtraction being positive, that is, 1 subtracted by the pvalue of Z when X = 0. Then
[tex]Z = \frac{X - \mu}{\sigma}[/tex]
[tex]Z = \frac{0 - 0.32}{0.151}[/tex]
[tex]Z = -2.12[/tex]
[tex]Z = -2.12[/tex] has a pvalue of 0.0170
1 - 0.0170 = 0.9830
0.9830 = 98.30% probability that the sum of three one-pound bags exceeds the weight of one three-pound bag

What is the weight on Earth of a girl with a mass of 30 Kg? The acceleration due to gravity on Earth is 9.8 m/ s 2.
ex
Answer: If, on earth, your mass is 30kg, then your weight is m*g which is mass (30kg) times Earth gravity (9.8m/s^2) = 294 N.
Step-by-step explanation:
The weight of a girl would be 294 N on Earth with a mass of 30 Kg.
What are Arithmetic operations?Arithmetic operations can also be specified by the addition, subtract, divide, and multiply built-in functions.
+ Addition operation: Adds values on either side of the operator.
For example 4 + 2 = 6
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 4 -2 = 2
* Multiplication operation: Multiplies values on either side of the operator
For example 4*2 = 8
The weight on Earth of a girl would be the product of the mass and acceleration due to gravity on Earth
So the required solution would be:
⇒ weight = mass × acceleration due to gravity on Earth
⇒ weight = 30 × 9.8
⇒ weight = 294 N.
Hence, the weight of a girl would be 294 N on Earth with a mass of 30 Kg.

2) y = –2x – 1
y = 3x – 16
Answer:
[tex]\left \{ {{x=3} \atop {y=-7}} \right.[/tex]
Step-by-step explanation:
We can directly substitute y of the first equation to the second equation.
-2x - 1 = 3x - 16
5x = 15
x = 3
Substituting back to any of the two equations, we get y = -2(3)-1 = -7. If you check with the second equation, y = 3(3)-16 = -7 as well.
Therefore [tex]\left \{ {{x=3} \atop {y=-7}} \right.[/tex].
