Tamara is 7 years older than her sister. The sum of their age is 27.
What is Tamara's age ?
Answer:
17 years old.
Step-by-step explanation:
If Tamara was 7 years younger, she would be as old as her sister. In that case, the sum of their ages would be 20, and since they'd both be the same age, 20 would just be Tamara's sister's age doubled. Half of 20 is 10, so Tamara's sister must be 10 years old, and at 7 years older, Tamara must be 17.
Answer:
17
Step-by-step explanation:
Tamara = x+7
sis= x
x+x+7= 27
2x= 27-77
x= 20/ 2= 10
tamara = 10+7 = 17

a village school starts at 8.30am and end at 3.45pm.how long is the school day
Answer:
7 hours and 15 minutes.
Step-by-step explanation:
Draw a timeline for this question.
8.30 + 7 hours = 3.30pm or 15 30
3.30 + 0.15 minutes = 3.45 or 15 45
7 hours + 0.15 minutes = 7 hours and 15 minutes.

Solve for h. 2h divided by 15 = 20 *
Answer: h=150
Step-by-step explanation:
2h/15 = 20
2h= 20*15 [multiply 15 in both side]
2h= 300
h= 300/2
h= 150
A cone has a radius of 10 meters and a height of 5 meters. What is the volume of the cone to the nearest cubic meter? Use 3.14 for
Answer:
523.3
Step-by-step explanation:
The volume of a cone is 1/3 hB where h is the height and B is the area of the base.
Step 1: Find the area of the base (B). The base of a cone is a circle so use the formula pi*r^2. Plug in numbers. 3.14*10^2. 3.14*100=314
Step 2: Plug into the formula. 1/3(5*314) --> 1/3(1570)=523.3

A Hertz Rent-a Car is a car agency charges $40 for one day plus $0.10 per mile to rent a full size car. Enterprise Rent-A-Car charges $18 for one day plus $0.20 cents per mile to rent the same car. How many miles could you drive in one day that would result in the final bill to be the same from both companies?
Answer: 220 miles
Step-by-step explanation:
Let's write the equations for each case:
A Hertz Rent-a Car:
Charges a fixed amount of $40, plus a $0.10 per mile.
Then if you drive x miles, we get a total cost of:
C(x) = $40 + $0.10*x
Enterprise Rent-A-Car:
Chares a fixed amount of $18 plus $0.20 per mile, so if you drive x miles, the cost is:
K(x) = $18 + $0.20*x
Now, we want to find how many miles you can drive such that you would pay the same in both companies.
Then we need to find x such that:
C(x) = K(x)
$40 + $0.10*x = $18 + $0.20*x
Let's solve this for x.
$40 - $18 = $0.20*x - $0.10*x
$22 = ($0.20 - $0.10)*x
$22 = $0.10*x
$22/$0.10 = x
220 = x
So if you drive exactly 220 miles, you would pay the same in both companies.

A rod is sliding down the side of a wall such that the height is decreasing at a rate of 5 inches per second. If the rod is 174 inches long, what is the rate of change of the distance between the bottom of the rod and the base of the wall when the height is 35 inches?
Answer: The rate of change of the distance between the bottom of the rod and the base of the wall when the height is 35 inches = 1.02675 inches per second.
Step-by-step explanation:
Let h = height, x= distance between the bottom of the rod and the base of the wall.
Given: [tex]\dfrac{dh}{dt}[/tex] = 5 inches per second
Consider the diagram (given in the attachment below):
By Pythagoras theorem, we have
[tex](174)^2=h^2+x^2\ \ (i)\\\\$$30276=35^2+x^2 \ \ \ [h=35 \ in.]\\\\ 30276=35^2+x^2 \\\\ 30276=1225+x^2\\\\ x^2=30276-1225\\\\ x^2 = 29051 \\\\ x=\sqrt{29051}\approx170.447 in.[/tex]
Differentiate both sides of (i) w.r.t t, we get
[tex]0=2x\dfrac{dx}{dt}+2h\dfrac{dh}{dt}\\\\\dfrac{dx}{dt}=\dfrac{-h}{x}\dfrac{dh}{dt}[/tex]
[tex]\dfrac{dx}{dt}=\dfrac{-35}{170.44}(-5)=1.02675\text{ inches per second }[/tex]
Hence, the rate of change of the distance between the bottom of the rod and the base of the wall when the height is 35 inches = 1.02675 inches per second.

let f:A=B such that f(x)=y and g:B=C such that g(y)=z.name the function defined from A to C.
Answer:
since g:B→C is onto
suppose z∈C,there exists a pre-image in B
Let the pre-image be y
Hence y∈B such that g(y)=z
similarly f:A→B is onto
suppose y∈B,there exists a pre-image in A
Let the pre-image be x
Hence x∈A such that f(x)=y
Now gof(x)=g(f(x))=g(y)=z
So for every x in A,there is an image z in C
