Answer:
45 in 6 hours
Step-by-step explanation:
3 inches in 2 minutes
So every hour, it can do 90 inches (since we multiply 2 times 30, we have to multiply 3 times 30)
So next we need to find out how much it goes in 6 hours, so we take 6 x 90. That gives us 540.
Lastly, we take 540 and divide it by 12 (since there are 12 inches in a foot) and that gives us 45 feet in 6 hours.
Answer:
540 feet
Step-by-step explanation:
Convert hours to minutes - 6 * 60 = 360 minutes
3 inches in 2 minutes = 1.5 inches in 1 minute (I did this just to make the next steps easier)
Figure out the number of feet moved in 6 hours - 1.5 * 360 = 540 feet

Tisha and her scout troop are heading to the Swing Time zipline park. They plan to purchase
the group package. With the package, the cost per person is $5 less than the normal cost for
an individual. There are 12 scouts in Tisha's troop. Her troop leader called ahead and found
that the total cost for the group will be $150. What is the normal cost for an individual?
Answer:
$17.5
Step-by-step explanation:
divide 150 by 12 to get 12.5. 12.5 is what they paid per-person with the discount. add 5 to get 17.5 and that is the on-discounted price
The normal cost for an individual is $17.50.
Let's denote the normal cost for an individual as "N."
According to the given information, with the group package, the cost per person is $5 less than the normal cost for an individual. So, the cost for each scout in Tisha's troop is "N - $5."
There are 12 scouts in Tisha's troop, so the total cost for the group is given as $150.
We can set up an equation based on the total cost:
Total Cost = Cost per Person × Number of People
$150 = (N - $5) × 12
Now, let's solve for the normal cost for an individual (N):
$150 = 12N - $60
12N = $150 + $60
12N = $210
N = $210 / 12
N = $17.50
So, the normal cost for an individual is $17.50.

Select the equation of the line that passes through the point (2, –1) and has slope 3 in point-slope form.
(y + 1) = 3(x – 2)
(y – 1) = 3(x + 2)
(x + 2) = 3(y – 1)
(x – 2) = 3(y + 1)
Answer:
(y + 1) = 3( x +2)
Step-by-step explanation:
from equation,
y - y1 = m( x - x1)
given x1=2, y1= -1
m = 3 (slope)
substitute
y - (-1) = 3( x - 2)
ans: y+1= 3(x+2)

6. A rectangle with a length of 15 feet has a
diagonal that measures 17 feet. Find the
perimeter of the rectangle.
Answer:
46 feet
Step-by-step explanation:
it is a 8-15-17 Pythagorean Triple (or you can use the Pythagorean theorem)
P=8+8+15+15=46
The perimeter of the rectangle with a length of 15 feet and has a diagonal that measures 17 feet is: A. 46 feet.
What is the Perimeter of a Rectangle?To find the perimeter of the rectangle, we need to know the width of the rectangle. Let's call the width of the rectangle W.
In a rectangle, the diagonal, length, and width are related by the Pythagorean theorem:
Diagonal² = Length² + Width²
In this case, the diagonal (D) is 17 feet, and the length (L) is 15 feet. So we have:
17² = 15² + W²
289 = 225 + W²
Now, let's solve for W:
W² = 289 - 225
W² = 64
W = √64
W = 8 feet
Now that we know the width is 8 feet, we can calculate the perimeter (P) of the rectangle:
Perimeter = 2 * (Length + Width)
= 2 * (15 + 8)
= 2 * 23
Perimeter = 46 feet

pls help with this maths question... feels like I'm missing something easy ;/
Answer:
10.34 cm.
Step-by-step explanation:
First we need to calculate the angle between the hour and minute hand
We see that there are 5 * 5-minute intervals between the 2 hands and the clock has 12 * 5-minute intervals, so:
This is 5/12 * 360 = 150 degrees,
So we apply the Cosine Rule to the triangle:
x^2 = 4.5^2 + 6.2^2 - 2*4.5*6.2cos150
= 107.014
x = √107.14 = 10.34.
Missing length is 10.3cm to 1.d.p
The clock is a circle divided into 12
360/12=30 degrees for each part
1) 7 to 8
2) 8 to 9
3) 9 to 10
4) 10 to 11
5) 11 to 12
5 parts
30 x 5 = 150 degrees
We've got an angle between 2 lengths - cosine rule comes to mind for me.
a = root 6.2^2 + 4.5^2 - 2x6.2 4.5 x cos 150
= 10.34476764
length is 10.3cm to 1.d.p
(the others are to 1.d.p too)

Answer:
The median is 69.5
Step-by-step explanation:
The median is also known as the middle value. To find the median, you first arrange your data in numerical order.
Numerical order:

A notebook costs £1.60, a pen costs 37p, a pencil costs 21p and a sharpener costs 86p.
Remi buys 3 pencils, 2 pens, 3 sharpeners and some notebooks.
He pays with £8 and receives 85p change.
How many notebooks did he buy?
notebooks
Answer:
2
Step-by-step explanation:
£1 = 100p
3*21p+2*37p+3*86p+x*160p (x is the number of notebooks)
63p+74p+258p+x*160p = 395p+x*160p
He paid £8 so he paid 800p
800p-395p = 405p
405p-85p = 320p
320p:160p = 2
He bought 2 notebooks
