A farmer has 113 sheep. 47 of them are males. How many more female sheep are there than make sheep?
113-47 = 66 female sheep
66-47 = 19
19 more female sheep than male sheep
The total number of sheep the farmer has is 113 sheep. Since 47 of them are males and you are solving for the number of female sheep, you can subtract 47 sheep from 113 sheep.
113 - 47 = 66
We have figured out that there are 113 total sheep, 47 male sheep, and 66 female sheep. The question is asking for how many more female sheep are there than male sheep, so subtract the number of male sheep from the number of female sheep.
female sheep - male sheep = answer
66 - 47 = 19
There are 19 more female sheep than there are male sheep.

What is the pre-image of vertex A' if the rule that created the image is ry-axis(x, y) → (–x, y)?
Answer:
It is given that image of any point (x,y) is (-x,y).
It is the case of reflection of a point through Y - axis.
So , Image of point (x,y) is (-x,y).
it's pre-image will be Point A whose coordinate is (x,y).
Answer: Preimage of A' is A (x,y).
Step-by-step explanation:
Suppose we have given a point A' (-x,y) and let [tex]r_y[/tex] be the rotation transformation with center of rotation at origin(0,0) such that
[tex]r_y (x,y) =(-x,y) \\[/tex]
Now in rotation transformation of any point about y axis i.e.( [tex]r_y[/tex]) it produces the reflected image by changing the polarity of x abscissa only and not of y. Therefore, by applying rotation transformation about y axis on image A'(-x,y) gives the pre-image of (-x,y) = (x,y) [which is the reflection of A'].
For example :- let P (1,2) be any point then after rotation transformation about y axis it will become P'(-1,2).

A vegetable-oil recovery plant has already recycled 1,400 litters out of 2,500 liters of used oil. If the plants can recycle 24 liters of used oil per hour, about how many hours will it take to recycle what is left?
A vegetable-oil recovery plant has already recycled 1,400 litters out of 2,500 liters of used oil.
Initially plant has 2,500 liters of used oil.
plant has already recycled 1,400 liters
so liters of oil left = 2500 - 1400 = 1,100
So 1,100 liters of oil left
plants can recycle 24 liters of used oil per hour
So for 1,100 liters we divide by 24 to find the number of hours
[tex]\frac{1100}{24}= 45.83[/tex]
Its approximately 46 hours
Approximately 46 hours it will take to recycle 1,100 liters.

which of the following are solutions to the quadratic equation? x^2 + 8x + 16 =7
E and F
note that x² + 8x + 16 is a perfect square which factors as ( x + 4 )², thus
(x + 4 )² = 7 ( take the square root of both sides )
x + 4 = ± √7 ( note plus or minus )
subtract 4 from both sides )
x = ± √7 - 4
x = √7 - 4 → E
x = - √7 - 4 → F

What is the slope of a line that is perpendicular to the line whose equation is 2x + y = 4
The slope of the line of the equation given is -2 (by solving for y, you get y = -2x+4).
So, in order to be perpendicular, you must take the negative reciprocal.
The slope would be -1/2.
slope = [tex]\frac{1}{2}[/tex]
the equation of a line in \ slope-intercept form ' is
y = mx + c ( m is the slope and c the y-intercept )
2x + y = 4 ( subtract 2x from both sides )
y = - 2x + 4 ← in slope-intercept form
with m = - 2
given a line with slope m then the slope ([tex]m_{2}[/tex]) of a line perpendicular to it is
[tex]m_{2}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{-2}[/tex] = [tex]\frac{1}{2}[/tex]
Amelia swam four times as many laps as wesly . Wesley swam 7 laps. How many laps did amelia swim??????
Final answer:
Amelia swam 28 laps, which is four times the 7 laps that Wesley swam.
Explanation:
In solving the question about the number of laps Amelia swam, a straightforward multiplication approach is employed. Given that Amelia swam four times as many laps as Wesley, and Wesley's lap count is specified as 7, the calculation involves multiplying Wesley's laps by 4. In mathematical terms, Amelia's number of laps is determined as Wesley's laps multiplied by 4, resulting in 7 × 4 = 28 laps.
This multiplication process provides a clear and concise method to ascertain Amelia's lap count based on the given relationship, demonstrating a fundamental application of arithmetic principles in solving real-world problems involving numerical relationships and operations.

Since the sum of the probabilities of all possible outcomes must be 100%, we can deduce the following:
Cooking in under 20 minutes: 10%Cooking between 20 and 30 minutes: 85%Cooking in more than 30 minutes: 5%In fact, the probabilities of cooking in less than 20 or more than 30 sum up to 15%, which means that the remaining outcome (i.e. cooking time between 20 and 30) must complete this probability to 15, and in fact 15+85=100.
That being said, all three answers are simply a combination of these three scenarios: let C be the cooking time, for aesthetic reasons:
[tex]P(C\geq 20) = P(20 \leq C \leq 30)+P(C\geq30) = 85\%+5\%=90\%[/tex]
[tex]P(20 \leq C \leq 30) = 85\%[/tex]
[tex]P(C\leq 30) = P(C\leq20)+P(20 \leq C \leq 30) = 10\%+85\%=95\%[/tex]
If y varies inversely as x, find the constant of variation if y = 5 when x = -1.
a) -5
b) 5
c) -2
d) 2
(a) - 5
since y varies inversely as x then k = yx ( k is the constant of variation )
using y = 5 when x = - 1, then k = 5 × - 1 = - 5
In a parallel circuit, ET = 208 V, R = 39 kΩ, and XL = 24 kΩ. What is the power factor?
Answer:
Power factor is 0.8517 or 85.17%
Step-by-step explanation:
We are given that in a parallel circuit, [tex]E_{T}=208V[/tex], R=39kΩ and [tex]X_{L}[/tex]=24kΩ.
That means the circuit has a resistor element, inductor element in parallel with 208V applied across the terminal.
Let us find the current through resistor,
[tex]I_{R} =\frac{E_{T}} {R}= \frac{208}{39} =\frac{16}{3}=5.33[/tex] milli amps
And current through inductor,[tex]I_{L} =\frac{E_{T}} {X_{L}} =\frac{208}{24}=\frac{26}{3}=8.667[/tex] milli amps.
Hence total current, [tex]I_{T}= \sqrt{(I_{R})^2+(I_{T})^{2}} =\sqrt{5.33^{2}+8.667^{2}}=10.176[/tex]
Now power factor=[tex]\frac{I_{R}}{I_{T}}=\frac{5.33}{10.176}=0.8517[/tex]
Hence power factor is 85.17% or 0.8517

A police officer had a taxable income of $47,050 last year. If she paid 10% of her income between $0 and $8350, 15% of her income between $8350 and $33,950, and 25% of her income between $33,950 and $47,050 in federal income tax, how much did the police officer pay in federal income tax last year? a. 3840 b. 3275 c.835 d. 7950
Answer:
The correct option will be: d. 7950
Step-by-step explanation:
The police officer paid 10% of her income between $0 and $8350, 15% of her income between $8350 and $33,950 and 25% of her income between $33,950 and $47,050 in federal income tax.
So, the amount of tax at 10% rate [tex]=(\$8350-\$0)*0.10=\$8350*0.10 = \$835[/tex],
the amount of tax at 15% rate [tex]=(\$33950-\$8350)*0.15 = \$25600*0.15=\$3840[/tex]
and the amount of tax at 25% rate [tex]= (\$47050-\$33950)*0.25= \$13100*0.25= \$3275[/tex]
Thus, the total amount of federal income tax will be: [tex](\$835+\$3840+\$3275)= \$7950[/tex]

43 - 3d= d + 9
Solution
Add 3d to both sides of the equal sign
43 = d + 3d + 9
43 = 4d + 9 Subtract 9 from both sides
43 - 9 = 4d Collect like terms on the left
34 = 4d Divide by 4 on both sides.
34/4 = 4d/4
8 2/4 = d
d = 8 2/4 = 8 1/2 = 8.5
