Answer:
When Kiran is 13, his aunt will be 28.
When Kiran's aunt is 60, he will be 45.
Step-by-step explanation:
Hope this helps!
Answer:
a) 28 (kiran's aunt when kiran is 13)
b) 45 (kiran when kiran's aunt is 60)
Step-by-step explanation:
first
let kiran's age be k
kiran's aunt= 15 + k
when kiran is 13, kiran's aunt is 15+13
15+13= 28
when kiran's aunt is 60;
15+k = kiran's age
60 = 15+ k
k = 60-15
k = 45
Write the equation of a circle with a center of (1,-2) and radius of 4.
Answer:
(x - 1)^2 + (y + 2)^2 = 4^2
Step-by-step explanation:
The standard equation of a circle of radius r with center at (h, k) is
(x - h)^2 + (y - k)^2 = r^2
Replacing h with 1, y with -2 and r with 4, we get:
(x - 1)^2 + (y + 2)^2 = 4^2

Prasad worked 15 hours this week and earned $195. Assuming he is paid by the hour, how much will Prasad earn next week if he is scheduled to work 12 hours?
Answer:
$156
Step-by-step explanation:
First you must find out the number of dollars Prasad receives per hour.
Since he earns $195 in 15 hours we can do 195/15 = 13 to find out the amount of dollars he earns per hour which is $13.
Next we must find out how much money he receives when he work for 12 hours so we simply do 13 (payment per hour) * 12 (amount of hours he works) which will give us $156!
This makes sense cuz 156 is a little bit less than 195 and ofc 12 is a little bit less than 15!
Prasad earn $156 next week if he is scheduled to work 12 hours
What is Ratio?A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0.
Prasad worked 15 hours this week and earned $195
We have to find the amount earned by prasad for work 12 hours
Let us form an proportional equation.
Let x be the amount earned for 12 hours
15/195 = 12/x
Apply cross multiplication
15x=195(12)
15x=2340
Divide both sides by 15
x=2340/15
x=156
Hence, Prasad earn $156 next week if he is scheduled to work 12 hours

Answer:
Area of a rectangle = 7/12 of an inch
Step-by-step explanation
Area of a rectangle = Length × width
In this case, the length is represented by height
Height = 2/3 of an inch
Width = 7/8 of an inch
Area of a rectangle = Length × width
= 2/3 × 7/8
= (2 * 7) / (3 * 8)
= 14 / 24
= 7 / 12
Area of a rectangle = 7/12 of an inch

A turtle and a snail are 360 meters (who counts this again?) apart, and they start to move towards each other at 3 pm. If the turtle is 11 times as fast as the snail, and they met at 3:40 pm, find the speed of each.
Thank you!! :)
Answer:
Turtle = 11 m / min
Snail = 1 m / min
Total approach speed = 12 m/min
360 m / (12 m/min) = 30 min
Separation is 30 min at assumed speed of 1 m/min
But we know the separation is 40 min
So turtle moves at 3/4 * 11 m / min = 33 m/ 4 min
Snail moves at 3/4 * 1 m /min = 3/4 m / mi
Total approach speed = (33 + 3) / 4 = 9 m / min
So in 40 min
9 m / min * 40 min = 360 m
(Leaving out those units, they approach at 12 * unit of speed)
So the unit of speed has to be 360 m / 40 min = 9 m / min

y = x − 1
x = 4
Answer:
2nd
Step-by-step explanation:
The equation of a line that is tangent to circle A from point C (9, 8) will be option C; y = x − 1.
How to get straight line equation?If the slope of a line is m and the y-intercept is c, then the equation of that straight line is given as:
y = mx +c
Given; Circle A is located at (6, 5) and has a radius of 3 units.
The slope;
m = (8- 5)/(9 -6) = 1
Substitute in the equation of line;
y = mx +c
8 = 1(9) + c
8 - 9 = c
c = -1
So, We get
y = x − 1
Hence the equation of a line that is tangent to circle A from point C (9, 8) will be option C; y = x − 1.

the volume of a cube is 710 cm cubed work out the length of its side rounded to one decimal place
Answer:
8.9cm
Step-by-step explanation:
Volume of a cube = L × L × L = L³
710 = L³
L = ³√710
L= 8.9 cm
The length of each side of Cube is 8.9 cm.
What is Volume of Cube?The length is to be multiplied by itself three times to get the volume. The volume is measured in cubic units.
For example, cubic units.
Given:
Volume of a cube is 710 cm.
So, Volume of Cube = l³
710 = l³
l = ∛710
l = ∛ (71 x 10
l = 8.9 cm

-by finding 25% off of $60, and
-by finding 15% off of $60, and then subtracting 10% from that cost.
Use the drop-down menus to complete your explanation.

25% off of $60 is equal to $45.00/35.00/25.00/45.90

15% off of $60, then subtracting 10% from that cost is equal to 35.00/25.00/38.25/45.90...
.
The two total costs are equal/not equal
can someone help me solve this question pls?
Answer:
No, Jeremy can not find the cost of the sneakers by adding the percents, you have to math one sale discount at a time.
The answer is $45.90.
Step-by-step explanation:
You have to multiply $60 by 15%, getting $9. Subtract 9 from 60 and get the first discount price: $51. Then you will multiply 51 by `10% and get 5.1, subtract 5.1 from 51 and get your final sale price of $45.90. If you added the percents together you would get an incorrect value of $45. Close but not the correct answer.
