what is 7 1/2 divided by 5 5/8
Answer:
1.33
Step-by-step explanation:
9514 1404 393
Answer:
4/3
Step-by-step explanation:
If you're familiar with decimal equivalents (or even if you're not), you can use your calculator to compute the quotient:
7.5/5.625 = 1.333333333...
The rational number equivalent of the result is 4/3.
__
If you like to work directly with the rational numbers, you can write the ratio as ...
(7 1/2)/(5 5/8) = (7 4/8)/(5 5/8) = (60/8)/(45/8) = 60/45 = 4/3
Joe measured the diameter of a tennis ball correct to the nearest millimetre. The upper bound of his measurement was 6.75 centimetres. Write down, in imillimetres, the lower bound of his measurement.
The lower bound of the measurement is 65.5 millimetres.
A centimetre equals 10 millimetres, a measure is expressed by the measured magnitude plus uncertainty, the latter one represents the grade of precision of the measure instrument. That is to say:
[tex]y = x + \epsilon[/tex] (1)
Where:
[tex]x[/tex] - Measured magnitude, in millimeters.[tex]y[/tex] - Possible magnitude, in millimeters.[tex]\epsilon[/tex] - Uncertainty, in millimeters.If we know that [tex]y = 67.5\,mm[/tex] and [tex]\epsilon = 1\,mm[/tex], then the lower bound of the measurement is:
[tex]y = 67.5\,mm - 2\cdot (1\,mm)[/tex]
[tex]y = 65.5\,mm[/tex]
The lower bound of the measurement is 65.5 millimeters.

using de moivre's theorem to find square roots of (2-2√ 3 i)
Let z = 2 - 2√3 i. In polar form, we have
[tex]z = |z| e^{i\arg(z)}[/tex]
where
[tex]|z| = |2-2\sqrt3| = \sqrt{2^2 + (-2\sqrt3)^2} = 4[/tex]
[tex]\arg(z) = \tan^{-1}\left(-\dfrac{2\sqrt3}2\right) = -\tan^{-1}(\sqrt3) = -\dfrac\pi3[/tex]
Equivalently,
[tex]z = 4\left(\cos\left(-\dfrac\pi3\right) + i\sin\left(-\dfrac\pi3\right)\right)[/tex]
Let w be a complex number such that w ² = z. By DeMoivre's theorem,
[tex]z = 4\left(\cos\left(-\dfrac\pi3\right) + i\sin\left(-\dfrac\pi3\right)\right) \\\\ \implies z^{1/2} = 4^{1/2} \left(\cos\left(\dfrac{-\frac\pi3+2k\pi}{2}\right) + i \sin\left(\dfrac{-\frac\pi3+2k\pi}{2}\right)\right)[/tex]
where k ∈ {0, 1}. So the two square roots of z are
[tex]z^{1/2} = \begin{cases}2\left(\cos\left(-\dfrac\pi6\right) + i\sin\left(-\dfrac\pi6\right)\right) & \text{for }k=0 \\\\ 2\left(\cos\left(\dfrac{5\pi}6\right) + i\sin\left(\dfrac{5\pi}6\right)\right) & \text{for }k=1\end{cases}[/tex]
[tex]z^{1/2} = \begin{cases}2\left(\dfrac{\sqrt3}2 - \dfrac12 i\right) & \text{for }k=0 \\\\ 2\left(-\dfrac{\sqrt3}2 + \dfrac12 i\right) & \text{for }k=1\end{cases}[/tex]
[tex]\boxed{z^{1/2} = \begin{cases}\sqrt3 - i & \text{for }k=0 \\ -\sqrt3 + i & \text{for }k=1\end{cases}}[/tex]

Answer:
(c) a = 14; b = 6√2
Step-by-step explanation:
If you draw a vertical line at the right end of the top segment, it will cut off an isosceles right triangle to its right. That triangle is shown as having a leg length of 6, so the length of 'a' is ...
a = 8 +6 = 14
The hypotenuse of an isosceles right triangle is √2 times the leg length, so ...
b = 6√2

Answer:
= 17.25 pounds (Answer)
Step-by-step explanation:
Potatoes she bought = 23 pounds
Amount she gave outsiders= 10+15=25%
= 23×25/100= 23/4=5.75 pounds
Potatoes left with her= 23 — 5.75
= 17.25 pounds (Answer)
Answer:
17.25 pounds
Step-by-step explanation:
10% of 23 is 2.3
15% of 23 is 3.45
Add them together you get 5.75
Subtract 5.75 from 23
Answer is 17.25

8. To calculate 159 - 73, a student writes the follow-
ing equations:
160 - 70 = 90 - 3 = 87 - 1 = 86
Although the student has a good idea for solving the problem, their equations are not correct. In words, describe the student's solution strategy and discuss why the strategy makes sense; then write a correct sequence of equations that correspond to
this solution strategy.
Write your equations in the following form:
159 - 73 = some expression
= some expression
=….
= 86
The question is an illustration of solving equations using estimates.
The student's strategy makes sense because he uses estimation to solve the given equation
The correct sequence of equation is as follows:

[tex]\mathbf{159 - 73}[/tex]
Add 0 to the equation
[tex]\mathbf{159 - 73 =159 + 0- 73}[/tex]
Express 0 as 1 - 1
[tex]\mathbf{159 - 73 =159 + 1 - 1- 73}[/tex]
[tex]\mathbf{159 - 73 =160 - 1- 73}[/tex]
Add another 0
[tex]\mathbf{159 - 73 =160 - 1- 73 + 0}[/tex]
Express 0 as 3 - 3
[tex]\mathbf{159 - 73 =160 - 1- 73 + 3 - 3}[/tex]
[tex]\mathbf{159 - 73 =160 - 1- 70 - 3}[/tex]
Rewrite as:
[tex]\mathbf{159 - 73 =160 - 70- 1 - 3}[/tex]
Solve
[tex]\mathbf{159 - 73 =90- 4}[/tex]
[tex]\mathbf{159 - 73 =86}[/tex]

Dylan saves 7% of his $1450.00 bi-weekly net pay. Determine how many periods it will take for Dylan to have $5800.00 saved.
Answer:
Here,
2 weeks savings is 1450×(7/100) dollars = 101.5 dollars
So, Dylan can save,
101.5 dollars in 1 periods
1 dollars in 1/101.5 periods
5800 dollars in 5800/101.5 periods = 57.142 or 58 periods

robby raises holstein and jersey cows on his farm in the ratio of 7:5 if he has a total of 48 cows on his farm how many holstein cows does he own?
Answer:
28
Step-by-step explanation:
The total amount of cows is 48 and is split into 12 groups (7+5).
So 1 group is 48÷12=4
1 group=4
He owns 7 groups of Holstein cows.
So if 1 group is 4, 7 groups is 7x4=28.
28
The number of Holstein cows, if The ratio of Holstein and jersey cows is 7:5, and the Total number of cows is 48, is 28.
What is ratio?It is the contrast of two different quantities. For instance, if your father weighs 90 kg, and you weigh 30 kg, the weight ratio is 1:3. If b is not equal to 0, an ordered pair of numbers a and b, denoted as a / b, is a ratio. A proportion is an equation that equalizes two ratios.
Given:
The ratio of Holstein and jersey cows is 7:5,
Total number of cows = 48
Calculate the values as shown below,
Assume the number of Holstein cows is 7x
7x + 5x = 48
12x = 48
x = 4
Thus, the number of Holstein cows is 7 × 4 = 28
