Answer: [tex]64.36^{\circ}[/tex]
Step-by-step explanation:
According to the question,
PQ ║ RS
And, PQ and RS are cut by the same transversal CD.
Then, By the alternative interior angle theorem,
The alternative interior angles made by the transversal CD on parallel lines PQ and RS must be congruent.
Thus, [tex]\angle PXY\cong \angle XYS[/tex]
⇒ [tex]m\angle PXY = m\angle XYS[/tex] ( by the property of congruent angles )
Here [tex]m\angle PXY = 64.36^{\circ}[/tex]
⇒ [tex]m\angle XYS = 64.36^{\circ}[/tex]
Solve the equation for the letter L: A=LW
Answer:
[tex]L=A/W[/tex]
Step-by-step explanation:
we have
[tex]A=LW[/tex]
Solve for L means -------> isolate the variable L
so
Divide by [tex]W[/tex] both sides
[tex]A/W=LW/W[/tex]
Simplify
[tex]L=A/W[/tex]

Suppose that we have a system consisting of two interconnected tanks, each containing a brine solution. Tank A contains
x(t) pounds of salt in 200 gallons of brine, and tank B contains
y(t) pounds of salt in 300 gallons of brine. The mixture in each tank is kept uniform by constant stirring. When t = 0, brine is pumped from tank A to tank B at 20 gallons/minute and from tank B to tank A at 20 gallons/minute. Find the amount of salt in each tank at time t if x(0) = 10 and y(0) = 40.

The distance between two cities is one hundred miles, and a woman drives from one city to the other at a rate of fifty mph. At what rate must she return if the total travel time is three hours and forty minutes?
well in her first travel (when she goes to the anther city)
v1= 50mph
d1=100 m
t1=?
t=d/v=100/50=2h
that's meat that she will take 2hours during the first travel
and total travel time = 3h
she wants to take only 1 h in her second travel
v2=?
d2=100 m
t2= 1h
v2= d2 *t2 =100mph
total travel time is 3 hours and 40 minutes so i belive the correct answer is 60mph
Which equation shows y=−1/2x+4 in standard form?
A. 2x+y=8
B. x+2y=8
C. x+2y=-8
D. 2x-y=8
Answer: B. x+2y=8
Explanation:
The original equation is:
[tex]y=-\frac{1}{2}x+4[/tex]
The problem asks us to convert the equation in the standard form, so in the form
[tex]ax+by=c[/tex]
with a,b and c being integers.
In order to do that, first of all let's bring on the same side both x and y:
[tex]y+\frac{1}{2}x=4[/tex]
Now we want the coefficient in front of x to be an integer, so let's multiply each term by 2, and we get
[tex]2y+x=8[/tex]
and this corresponds to option B.
The equation that represents y = -1/2x + 4 in standard form is 2x + y = 8.
The equation that shows y = -1/2x + 4 in standard form is 2x + y = 8.

minimize Q=x^2+2y^2, where x+y=3
To minimize the function Q=x^2+2y^2, substitute x=3-y and expand the expression. Use the vertex formula to find the minimum value of Q. The minimum value is 13.5 when x=1.5 and y=1.5.
Explanation:To minimize the function Q=x^2+2y^2, where x+y=3, we can substitute x=3-y into the function to get Q=(3-y)^2+2y^2. Expanding this expression gives Q=9-6y+y^2+2y^2. Combining like terms, we have Q=3y^2-6y+9.
To find the minimum value of Q, we can use the vertex formula. The x-coordinate of the vertex of the parabola represented by Q=a(x-h)^2+k is x=-h. In our case, h=-(-3)/2=1.5. Substituting this value of x into the equation Q=3y^2-6y+9 gives Q=3(1.5)^2-6(1.5)+9=13.5-9+9=13.5.
Therefore, the minimum value of Q is 13.5 when x=1.5 and y=1.5.

Jake earns $7.50 per hour working at a local car wash. The function, ƒ(x) = 7.50x, relates the amount Jake earns to the number of hours he works. Write the inverse of this relation
For this case we have the following function:
[tex] f(x) = 7.50x
[/tex]
An equivalent way to write this function is:
[tex] y = 7.50x
[/tex]
From here, we clear the value of x.
We have then:
[tex] x = \frac{y}{7.50}
[/tex]
Returning the variables we have that the inverse of the function is:
[tex] f (x) ^ - 1 =\frac{x}{7.50}
[/tex]
Answer:
the inverse of this relation is:
[tex] f (x) ^ - 1 =\frac{x}{7.50}

The initial amount of people that are sick with the flu is 36 and growing at a rate of 8% every day.
How many people will be sick with the flu in 11 days?
Round to the nearest whole number.
Answer: 84
Step-by-step explanation:
36 Counts as day 0
Day 1 : 36 x 1.08 = 38.88
Day 2 : 38.88 x 1.08 = 41.9904
Day 3 : 41.9904 x 1.08 = 45.349632
Day 4 : 45.349632 x 1.08 = 48.97760256
Day 5 : 48.97760256 x 1.08 = 52.8958107648
Day 6 : 52.8958107648 x 1.08 = 57.127475625984
Day 7 : 57.127475625984 x 1.08 = 61.69767367606272
Day 8 : 61.69767367606272 x 1.08 = 66.6334875701477376
Day 9 : 66.6334875701477376 x 1.08 = 71.964166575759556608
Day 10 : 71.964166575759556608 x 1.08 = 77.72129990182032113664
Day 11: 77.72129990182032113664 x 1.08 = 83.9390038939659468275712
83.9390038939659468275712 rounded to the nearest whole number is 84.
Based on the number of people who were initially sick and the rate of increase, the number who will be sick in 11 days is 84 people.
To find the number who will be sick in 11 days use the future value formula:
= Initial people x ( 1 +rate) ^ number of days
Solving will give:
= 36 x ( 1 + 8%) ¹¹
= 83.9
= 84 people
In conclusion, 84 people will be sick.
