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
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

Draw an angle of -45 degrees in standard position . Then find the reference angle
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
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.

Find the volume and surface area of the composite figure. Give four answer in terms of π. HELP NEEDED NOW!!! THE RED IS THE ONE I GOT WRONG!!
Answer:
Divide the figure above into a cylinder and a dome
+) the volume of the dome is
[tex]v1 = \frac{1}{12} \pi6 {}^{3} = 18\pi[/tex]
the surface area is
[tex]s1 = \pi3 {}^{2} = 9\pi[/tex]
+) the volume of the cylinder is
[tex]v2 = \pi.3 {}^{2} .13 = 117\pi[/tex]
the surface area is
[tex]s2 = 2\pi.3.13 + 2\pi.3 {}^{2} = 96\pi[/tex]
so the volume of this figure is
[tex]v = v1 + v2 = 18\pi + 117\pi = 135\pi[/tex]
the surface area of this figure is
[tex]s = 9\pi + 96\pi = 105\pi[/tex]

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
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.

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.

Identify the lateral area and surface area of a regular triangular pyramid with base edge length 10 ft and slant
height 14 ft
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

A circle has a diameter of 8 cm. An angle in the center of the circle creates an arc AB. That angle's measure is pi/4 rad. What is the measure of arc AB
Answer:
3.14 cm
Step-by-step explanation:
From the question,
Applying
s = πdФ/360................... Equation 1
Where s = length of arc AB, d = diameter of the circle, Ф = angle at the center of the circle, π = pie
From the question,
Given: d = 8 cm, Ф = π/4 rad = 45°
Constant: π = 22/7
Substitute these values into equation 1
s = (22/7)(8)(45)/360
s = 3.14 cm.
Hence the lenght of arc AB = 3.14 cm
The diameter of a circle is 14 inches. Find the circumstance and area use 22/7
