=35 x 4 cm^2
=140 cm^2
area of the square
=10 x 10 cm^2
=100 cm^2
area of the polygon
=(100 + 140) cm^2

Every day after school, Kelly and Bella walk their dogs around the block. The block is 274 meters long and 80 meters wide. What is the perimeter of the bloc
Answers
Answer:
708meters
Step-by-step explanation:
Given data
Lenght = 274meters
Width= 80 meters
The expression for the perimeter is
P= 2L+2W
substitute
P= 2*274+ 2*80
P= 548+160
P= 708 meters
Hence the perimeter of the block is 708meters

Answer:
x = 30 and y = 50
Step-by-step explanation:
Given that,
The cost of 4 shirts and 1 pair of pants is $170 and the cost of 5 shirts and 2 pair of pants is $250.
Let the cost of 1 shirt is x and that of 1 pant is y.
So,
4x+y=170 .....(1)
5x+2y = 250 .....(2)
Multiply equation (1) by 2.
8x+2y=340 .......(3)
Subtract equation (2) from (3).
8x+2y-(5x+2y)=340-250
3x = 90
x = 30
Put the value of x in equation (1).
4(30)+y=170
120+y=170
y = 170-120
y = 50
Hence, the value of x is 30 and that of y is 50.

A cyclist rides his bike at 12 miles per hour. What is this speed per minute? How many miles will the cyclist travel in 20 minutes? Do not round you answers. Help thx
Answers
Answer:
In order to find the distance traveled in one minute, you have to divide the distance he can ride his bike in an hour by the number of minutes in a hour. 6/60= .1 mile per minute. If he rides his bike for five minutes, then you would multiply the number of minutes biked by the distance traveled in a minute. .1*5=.5 mile, or [tex]\frac{1}{2}[/tex] mile.
Step-by-step explanation:
The cyclist will travel 4 miles in 20 minutes.
What is Speed?Speed is the time rate at which an object is moving along a path,
To find the speed per minute, we can use the fact that there are 60 minutes in an hour. Therefore:
12 miles per hour = 12/60 miles per minute = 0.2 miles per minute
So the cyclist's speed is 0.2 miles per minute.
To find how many miles the cyclist will travel in 20 minutes, we can use the formula:
distance = rate x time
Plugging in the given values, we get:
distance = 0.2 miles per minute x 20 minutes
distance = 4 miles
Therefore, the cyclist will travel 4 miles in 20 minutes.

Answers
Answer:
L = 315 cm2 ; S = 399.9 cm2
Step-by-step explanation:
Lateral area;
3 × (½)(14)(15)
315 cm²
Surface area:
315 + (½)(14)(14)sin(60)
399.8704896 cm²
Lateral surface area of the regula triangular pyramid is 210 ft²
Surface area of the regular triangular pyramid is 253.30 ft²
Lateral area and Surface area of a triangular pyramid: Expression for the lateral area of a regular triangular pyramid is given by,
Lateral surface area = 3(Area of one lateral triangular side)
Expression for the total surface area is given by,Surface area = Area of the triangular base + Lateral surface area
Given in the question,
Base with the edge length = 10 feet Slant height = 14 ftLateral surface area = [tex]3(\frac{1}{2})(\text{Base})(\text{Slant height})[/tex]
= [tex]\frac{3}{2}(10)(14)[/tex]
= 210 ft²
Area of the regular triangular base = [tex]\frac{\sqrt{3} }{4}(a)^2[/tex]
= [tex]\frac{\sqrt{3} }{4}(10)^2[/tex]
= 25√3 ft²
= 43.30 ft²
Therefore, total surface area = 210 + 43.30
= 253.30 ft²
Hence, lateral surface area of the regula triangular pyramid is 210 ft²
Surface area of the regular triangular pyramid is 253.30 ft²

Draw an angle of -45 degrees in standard position . Then find the reference angle
Answers
Answer:
45°
Step-by-step explanation:
-45° would be 360°-45°=315°
Since 315° is in Quadrant IV, then its reference angle is 360°-315°=45°
So really, -45° is just 45° clockwise which is also our reference angle.

which equation represents a line parallel to y= -2x+9
Answers
The equation of the parallel line is:
y = -2x + k
such that k ≠ 9.
How to represent the parallel line?
We know that two linear equations are parallel if they have the same slope and different y-intercept.
Then, a parallel line to:
y = -2x + 9
Would be something of the form:
y = -2x + k
such that k ≠ 9.
Then, for example:
y = -2x + 3
Is parallel to the given line.
