Answer:
1344
Step-by-step explanation:
100cm = 1 m
Convert the dimensions of the floor to cm = Area of a rectangle = length x breadth = 320 x 280 = 89,600m²
Area of a square = length² = 10cm² = 100cm²
Number of tiles that would be needed = area of floor / area of square
89,600cm² / 100cm² = 896
Cost of one tile = rs 150 / 100 = 1.5
Cost of 896 tiles = 1.5 x 896 = 1344

Brent leaves school to go home. He walks 10 blocks north and then 6 blocks west. If Brent could walk in a straight line to the school, what is the exact distance between Brent and school
Answer:
11.66 units
Step-by-step explanation:
Given that he walks 10 blocks north and then 6 blocks west..
When combined with the straight line to the school, this forms a right angled triangle with the straight line as the hypotenuse.
Hence, let the straight line be h
h^2 = 10^2 + 6^2 (using Pythagoras theorem)
h^2 = 100 + 36
h^2 = 136
h = √ 136
h = 11.66 units

A boat travelled 336 km downstream with the current. The trip downstream took 12 hours.
a) Come up with an equation to describe this relationship
b) If the current is moving at 2 km/h, how fast is the boat moving from its engine?
Answer:
When travelling downstream, the speed of the boat and the current add up.
Let the speed of the boat is b and the speed of the current is c.
Use distance formula:
d = st, d-distance, s- speed, t- timea)
Then we have equation:
12(b + c) = 336b)
If c = 2, then the equation is:
12(b + 2) = 336b + 2 = 28b = 26 km/h12. The function M(h) = 10e-0.173h can be used to find the number of milligrams M of morphine that is
in the patient's bloodstream h hours after the drug has been administered.
(a) What was the initial dosage?
(b) How many milligrams will be present after 1 hour? After 4 hours?
please help..
Answer:
Part A; Initial dosage is 10 milligrams
Part B:
8.4113 milligrams after 1 hour
5.0057 milligrams after 4 hours.
Step-by-step explanation:
It is given M(h)= 10 [tex]e^{-0.173h}[/tex]
Initial dosage is the 10 milligrams
After 1 hour, plug in h as 1
So, M(1)=10[tex]e^{-0.173*1}[/tex]
Simplify the right side
M(1)=10(0.84113)
M(1)= 8.4113 milligrams.
Now, after 4 hours
M(4)=10 [tex]e^{-0.173*4}[/tex]
M(4)=10(0.50057)
M(4) =5.0057 milligrams
Determine if the sequence is geometric. If it is, find the common ratio. ( -4, 12, -36, 108, ... )
Step-by-step explanation:
to know whether it is geometric progression or not, you need to find the common ratio. to find the ratio divide the (n+1)th term by n th term
so, 12/-4 = -3
also, -36/12 = -3
here u see the ratio is always same, i.e., common ratio.
thus u can say it is a geometric series with common ratio -3

Students at Sunnyside Middle School are selling tickets to the annual talent show. Below is a table showing ticket prices for students and adults.
Talent show ticket prices
Student Price $3
Adult Price $5
What amount of money would be collect if 60 students and 30 adults bought tickets? Show or explain how you got your answer.
Answer:
$330
Step-by-step explanation:
$3 times 60 students = $180
$5 times 30 adults = $150
$180 + $150 = $330
Answer:
Step-by-step explanation:
you would find your answer by multiplying the amount of students/adults by how much each ticket costs
60 x $3 = $180
30 x $5 = $150
$180 + $150 = $330
Consider the rectangle. Which pair of expressions represents the perimeter of the rectangle?
PLEASE HELP!!!
Answer:
6x + 2 and 2x + (x + 1) + 2x + (x + 1)
Step-by-step explanation:
Perimeter of a rectangle = 2(length + width)
Length = 2x
Width = x + 1
Perimeter of a rectangle = 2(length + width)
= 2{2x + (x + 1)}
= 2(2x + x + 1)
= 2(3x + 1)
= 6x + 2
Perimeter = length + width + length + width
= 2x + (x + 1) + 2x + (x + 1)

The approximate volume of first cone is 709[tex]mi^{3}[/tex] and the volume of second cone is 262 [tex]cm^{3}[/tex].
What is volume?Volume is amount of substance a container can hold in its capacity. Volume of cone is basically 1/3 *π[tex]r^{2}h[/tex] in which r is radius and h is height of cone.
How to calculate volume?We have been given two cones. First is having radius of 7 mi and
height 14 mi and second is having radius of 5 cm and height of 10 cm. We are required to find out the volume of both the cones.
Volume of first cone=1/3 *π[tex]7^{2}* 14[/tex]
=(49*3.14*14)/3

what is 5 times a number minus 3 is 12 ?
Answer:
5*x-3=12
the number is 3 because 5*3=15 and 15-3=12
Answer:
3
Step-by-step explanation:
x - 3 = 12
12 + 3 = 15
15 - 3 = 12
5( ? ) = 15
15/5
? = 3

1. Let x= -2 and y= -5. (NC.7.NS.2) Which expression has a negative value? A. X+y B.X-y C.[x] [y] D. X/y
Answer:
A. X + Y
Step-by-step explanation:
From this question x = -2 and y = -5
We are to find out the expression that would give a negative value.
X+Y
(-2)+(-5)
+(-) gives a negative sign. So we have
= -2-5
= -7
For x - y
(-2) - (-5)
-(-) = positive
= -2 + 5
= 3.
For [x][y]
= (-2) x (-5)
= 10
since a negative sign multiplied with another negative sign gives a positive result
For X/Y
= -2/-5
= 2/5 the result here is positive because 2 negative signs when divided cancel out.
Therefore the answer is option A since it's result is negative. Others are positive
The ratio of green bags to white bags in the store is equal to 2 to 5.There are 30 white bags in the store how many green bags are there?
Answer:
12 green bags
Step-by-step explanation:
Given data
The given ratio of green bags to white bags is
=2 to 5
=2:5
Number of white bags=30
Applying the part to part method, let the number of green bags be x
so
2/5=x/30
cross multiply
30*2=5x
60=5x
divide both sides by 5
x= 60/5
x=12
Hence there are 12 green bags
