The value of the given 2 digits number when the tens place digit is x write in terms of x is; 10x + y
How to find a two digit number?
We are given that the sum of a two digit number is 5.
Now, if the number is xy, then we can say that;
x + y = 5
Since x is the tens place digit, then we can say that the value of x is 10x and as such the value of the 2 digits is written as;
10x + y

You withdraw $140 from your savings account. then you withdraw $49 more. using an integer, which number represents your balance?
The integer represent the balance in your account is Z = + Y. The representation of integer is positive because withdrawal is always less then or equal to the amount present in the bank account.
Total rupees withdraw from saving account is $149
Let total amount in account before withdrawing is X= $500
Amount left after withdraw the money is calculated by a
AMOUNT LEFT = TOTAL AMOUNT - WITHDRAW AMOUNT
So, put the values then
Y= X($500) - $149
Y= $500 - $149
Y= $351
If we represent the balance of saving account in the integer form then it become the Z = + Y. The representation of integer is positive because withdrawal is always less then or equal to the amount present in the bank account.
So, The integer represent the balance in your account is Z = + Y. The representation of integer is positive because withdrawal is always less then or equal to the amount present in the bank account.

Write the equation for a parabola with a focus at (9,0) and a directrix at y=-4y
The required equation of parabola is y = (-1/4)(x-9)² +4
What is a Parabola ?
A parabola is a U shaped Curve , whose all point are at same distance from a point called as Focus and a line called as Directrix.
Let (x,y) be any point on the parabola.
the distance between (x,y) and the focus and the distance between (x,y) and directrix is equal.
The focus is at (9,0) and a directrix at y= - 4
[tex]\rm \sqrt {(x-9)^2 + (y -0)^2[/tex] = | y +4|
[tex]\rm {(x-9)^2 + (y -0)^2 = (y-4)^2[/tex]
(x-9)² + y² = y² +16 -4y
On solving this

the ratio equivalent to tan P and tan Q
Answer:
Tan p is 20/21
Tan q is 21/20
Step-by-step explanation:
Tan is short for tangeant.
tangeant means opposite/adjacent
the opposite of vertices p is 20.
the adjacent of vertices p is 21.
so tan p= 20/21
The opposite of vertices q is 21
the adjacent of vertices q is 20
so tan q is 21/20
Solve each triangle – find any missing side and angle measures. Round answers to the nearest tenth.
Answer:
A = 55 degrees
B = 35 degrees
C = 90 degrees
side BA = 4.8 units
side AC = 2.7 units
side BC = 3.9 units
Step-by-step explanation:
Hello!
The things we know:
A = 55 degrees
C = 90 degrees
side BA = 4.8 units
AC = adjacent side
BC = opposite side
AB = hypothenuse
B = 180 - 55 - 90 degrees
B = 35 degrees
Let's find side AC
we can use the cos of theta.
cos(55) = AC/4.8
multiply 4.8 on both sides.
4.8cos(55) = AC
AC = 2.7 units
And now we just have to find BC
to calculate BC we can either use tangent or sin.
I will just use sin
sin(55) = BC/4.8
multiply 4.8 on both sides.
4.8sin(55) = BC
BC = 3.9
And now we know everything about the triangle

The length of the rectangle is 8m and width of the rectangle is 7m
The perimeter of a rectangle is the total length around the outside of rectangle. The total boundary of the rectangle is its perimeter If length of the rectangle is l and breadth of the rectangle is b, then perimeter ofvthe rectangle is given by P = 2 (l+b)Given that the length and width of a rectangle are consecutive integers
Let the length of the rectangle be x+1 meter
Let the breadth of the rectangle be x meter
Also given that perimeter of the rectangle is 30 meters
To find length and breadth of the rectangle
We know that perimeter of the rectangle is P = 2 (l+b)

Which graph represents the rational function?It follows from the task content that the rational function given is; f(x) = 3x-2/x-2.
Hence, since the numerator and denominator polynomials are of the same order, it follows that the horizontal asymptote is the quotient; 3/1 = 3.
Additionally, the vertical asymptote of the function is the value of x which renders the denominator equal to 0 and consequently, the function undefined.
Hence, x -2 = 0 and x= 2.

Step-by-step explanation:
The law of sines states
[tex]\frac{a}{sinA} = \frac{b}{sinB} = \frac{c}{sinC}[/tex]
where a, b and c are the 3 sides of the triangle and A is the angle opposite side a, B the angle opposite side b and C the angle opposite side c
In this particular problem we have
side a = 44, angle A = 46.7
side c = ? , angle C = 48
So 44/sin(46.7) = c/sin(48) or by multiplying both sides by sin(48)
c = sin(48) * 44/sin(46.7) = 44.92937 which is 44.93 rounded to 2 decimal places

far from the plane is Bobby? Round to the nearest tenth of
a yard. Enter a number answer only.
The distance from Bobby to the plane is 154.7 yards.
How to find the distance of the plane to Bobby using angle of elevation?Sine law can be used to find the distance of the plane to Bobby.
Therefore,
x / sin 40 = 240 / sin 95
cross multiply
Hence,
x sin 95 = 240 sin 40
divide both sides by sin 95
x = 240 sin 40 / sin 95
x = 240 × 0.64278760968 / 0.99619469809
x = 154.08 / 0.9961
