Describe and correct the error in finding the perimeter or area of the polygon.
Answer:
Look at explanation.
Step-by-step explanation:
The error is that the length of the polygon is 5 not 4. The perimeter should be 16 units not 14 units.
The perimeter of the given polygon is 16 units.
What is the perimeter?The perimeter of a shape is defined as the total distance around the shape. It is the length of the outline or boundary of any two-dimensional geometric shape. The perimeter of different figures can be equal in measure depending upon the dimensions.
From the given figure, length =5 units and width =3 units.
We know that, the perimeter of a rectangle is perimeter =2(length+width)
P= 2l+2w
= 2(5)+2(3)
= 10+6
= 16 units
Therefore, the perimeter of the polygon is 16 units.

What is the slope of the following 2 points
(5,1) and (8,3)
Answer:
2/3
Step-by-step explanation:
use point slope formula: [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]to find the slope.
3-1=2
8-5=3
your slope is 2/3
Answer:
2/3
Step-by-step explanation:
The formula for slope is y2 - y1 over x2 - x1.

Jeremy is in a growth spurt, and his mother has been measuring his height once a month.
When she first measured, Jeremy was 49.5 inches tall, and every month afterward, his height
has increased by 0.75 inch each month.
Which equation models Jeremy's growth spurt, where n represents his height in inches, and
m represents time in months?
Ah 0.75m
B h - 0.75m + 49.5
Ch = 49.5m
Dh = 49.5m + 0.75
Answer:
B
Step-by-step explanation:
B. h = 0.75m + 49.5, models Jeremy's growth spurt, where h represents his height in inches, and m represents time in months.
What is multiplication?In mathematics, multiplication is a method of finding the product of two or more numbers. It is one of the basic arithmetic operations, that we use in everyday life.
here, we have,
Jeremy was 49.5 inches tall,
and every month afterward, his height has increased by 0.75 inch each month.
The equation models Jeremy's growth spurt, where h represents his height in inches, and m represents time in months is,
h =0.75m + 49.5
Hence, B. h = 0.75m + 49.5, models Jeremy's growth spurt, where h represents his height in inches, and m represents time in months.

19 is a prime number
Step-by-step explanation:
Answer:
19.
Step-by-step explanation:
The best way to find if a number is prime or not is that you divide that number with 3 and 7 if it is not divisible by either of them then it's a prime. If the one's digit is divisible by 2 it cannot be prime and if the one's digit is 0 or 5 then it is not prime.

This is an equation in words so let's start by putting it into numbers.
we know that John rides his bike for .23 miles and Angie rides her bike a whopping 100 TIMES as far. That means we would multiply.
.23 x 100 = 23
So that means Angie rides her bike for 23 miles.

A red ball rolls for 6 meters across a sticky level surface and slows down to a stop. the ball was rolling at 36 meters per second when it began to roll across the sticky surface. find the acceleration, velocity final, the velocity initial, the velocity average, the distance the ball rolled, and the time of the balls roll across the sticky surface
Answer:
Please find the answer in the explanation
Step-by-step explanation:
Given that a red ball rolls for 6 meters across a sticky level surface and slows down to a stop. the ball was rolling at 36 meters per second when it began to roll across the sticky surface. To find the acceleration, let us use third equation of motion
V^2 = U^2 + 2as
As the object is moving to stop, V = 0
0 = U^2 - 2as
36^2 = 2 × a × 6
1296 = 12a
a = 1296 / 12
a = 108 m/s
The velocity final = 0
The velocity initial = 36 m/s
the velocity average = (36 + 0)/2
Average velocity = 36/2 = 18m/s
the distance the ball rolled = 6m
and the time of the balls roll across the sticky surface will be achieved by using first equation of motion
V = U + at
V = 0
0 = 36 - 108t
108t = 36
t = 36 / 108
t = 0.3 seconds

Find the measures of the numbered angles in the figure, shown to the right. Name the theorem that justifies each
answer.
M<1=
M<2=
M<3=
M<4=
Answer:
Step-by-step explanation:
m∠1 + 75° = 180° [Linear pair of angles]
m∠1 = 180° - 75°
= 105°
m∠2 = m∠1 [Opposite angles of a rectangle are equal]
m∠2 = m∠1 = 105°
m∠2 = m∠3 = 105° [Vertically opposite angles]
m∠3 = m∠4 = 105° [Corresponding angles]
Therefore, all four angles measure the same as 105°.
