Find a unit rate: Joel ran 1500 meters in 5 minutes, 20 seconds.
Give your answer accurate to at least one decimal place.
Answers
Answer:
4.6875 m/s
Step-by-step explanation:
You want the unit rate if Joel ran 1500 m in 5 minutes, 20 seconds.
RateThe speed is found by dividing distance by time. In seconds, the time is ...
min:sec = 5:20 = (5·60) +20 = 320 . . . . seconds
Then the rate is ...
(1500 m)/(320 s) = 4.6875 m/s

Rise over run,
How many squares up until you get to the same level as the next point
That is your rise (top number)
Then count how many squares across til you are right on the point
That is your run (bottom number)
Remember that if it is going down or to the left it will be negative
do rise over run, the rise is 2 and the run is 5 therefore 2/5 but because the slope is downwards it will be minus 2/5
A 22-m by 14-m rectangular yard is to be seeded. Each bag of seed covers 18m². How many bags of seed are need?
Answers
18 bags!!
EXPLANATION!!
You need to find out how big the backyard is first by multiplying both lengths.
22•14=308
Knowing a bag covers 18m we need to divide.
308/18=17.1111
It asks for how many bags are needed, this is a real world situation so you need to round up to the nearest whole number so you would get 18!

The perimeter of a rectangular swimming pool is 154m. Its length is 2m more than twice its breadth. What is the length and breadth of the pool?
Answers
P be the perimeter of the pool
L = length of the pool
B = breadth of the pool
Given
======
P = 2L + 2B = 154 m
L = 2 + 2B
P = 2(2 + 2B) + 2B ……. Substitute
154 = 4 + 4B + 2B ……. Distribution
154 = 4 + 6B ……… Add like terms
154 - 4 = 6B
150 = 6B
150/6 = 6B/6 …….. Divide both sides by 6
25 = B …. Breadth
L = 2 + 2B
L = 2 + 2(25) = 2 + 50
L = 52
Length = 52 and breadth = 25

How to simplify the expression?The expression for this problem is defined as follows:
2³ + 6/3 - (-10/2)
The parenthesis takes precedence, hence:
2³ + 6/3 - (-5) = 2³ + 6/3 + 5
The power takes precedence, hence:
8 + 6/3 + 5
Division has higher precedence than addition, hence:
8 + 2 + 5.
Hence the result is given as follows:
8 + 2 + 5 = 15.

A regular polygon is shown, with the measure of one of its angles labeled 3x − 15.
8 sided regular polygon with one angle labeled 3 times x minus 15
Determine the value of x.
x = 40
x = 65
x = 50
x = 135
Answers
Answer:
x = 50
Step-by-step explanation:
The interior angle at each vertex of regular octagons are 135°.
3(50) - 15 = 135
For the polygon to be an 8 sided regular polygon like you said, the angle must equal 135, and so x must equal 50.
The required value of the x in the given expression is 50°.
Given that,
A regular polygon is shown, with the measure of one of its angles labeled 3x − 15.
What is a polygon?
A polygon is defined as a geometric shape that is composed of 3 or more sides these sides are equal in length, and an equal measure of angle at the vertex,
Examples of polygons, equilateral triangles, squares, pentagons, etc
Here,
For the octagon,
The angle of a vertex is 135°.
Equating the angles,
3x -15 = 135
3x = 135 + 15
3x = 150
x = 50
Thus, the required value of the x in the given expression is 50°.
