Answer:
36Step-by-step explanation:
Let the shortest side be x, the other sides are x + 2 and x + 4
Perimeter is:
P = x + (x + 2) + (x + 4) = 3x + 6It is given that:
1/4P = x - 1Substitute and solve for x:
1/4(3x + 6) = x - 13x + 6 = 4x - 44x - 3x = 6 + 4x = 10Perimeter is:
P = 3*10 + 6 P = 36HERE,
the lengths of the sides of a triangle are consecutive even integers.
If one angle=a
other are=(a+2) and (a+4)
So,
perimeter(p) =a+a+2+a+4=3a+6
But,
one fourth of the perimeter is one less than the length of the shortest side.
[tex]\bold{\dfrac{1}{4}p=a-1 }[/tex]
so,
According to the question,
[tex]\tt{\dfrac{1}{4}(3a+6)=a-1 }[/tex]
[tex]\tt{\dfrac{3a+6}{4}=a-1 }[/tex]
[tex]\tt{4(a-1)=3a+6 }[/tex]
[tex]\tt{ 4a-4=3a+6 }[/tex]
[tex]\tt{4a-3a=6+4 }[/tex]
[tex]\bold{ a=10 }[/tex]
so,
Perimeter (p)=3×10+6=30+6=36
perimeter of the triangle is 36 .

A square pyramid is shown:
What is the surface area of the pyramid?
A. 2.46 square feet
B. 8.76 square feet
C. 5.16 square feet
D. 1.56 square feet
Answer:
B.76 square feet
Step-by-step explanation:
SA=B+L
Answer: B) 8.76 square feet
=========================================================
Explanation:
The base is a square with side length 0.6 ft, so the base area is 0.6*0.6 = 0.36 square feet.
Each lateral triangular panel has base 0.6 ft and height 7 ft. The area of one triangle is 0.5*base*height = 0.5*0.6*7 = 2.1 square feet
So four of these triangles combined give a lateral surface area of 4*2.1 = 8.4 square feet. Add this onto the base area to get 8.4+0.36 = 8.76 square feet of total surface area.

A sign in a bakery gives these options:
15 cupcakes for $26
24 cupcakes for $42
40 cupcakes for $66
Find each unit price to the nearest cent, and show your reasoning.
Which option gives the lowest unit price?
Answer:
The lowest unit price would be last option
Step-by-step explanation:
We must divide the price by the amount of cupcakes we will be getting. Once we do that we'll get:
A. 1.77 cents
B. 1.75 cents
C. 1.65 cents
Hope this helped
Answer:
40 cupcakes for $66
Step-by-step explanation:
To find the unit price of something, dived the total amount by how may there are.
$26 divided by 15 cupcakes would be $1.7333333333, but if you round it up, it would be $1.74
$42 divided by 24 cupcakes would be $1.75
$66 divided by 40 cupcakes would be $1.65

Step-by-step explanation:
2.5(12.75x + 24.50) = 188.75
1. Simplify both sides of the
equation
(remove parentheses
and/or combine like terms).
2. Use inverse operations and
properties of equality to
"undo" what is happening to
the variable. (use the
reverse order of operations
because we are undoing)
3. Check your answer by
substituting your answer
into the original equation.
Answer:
Step-by-step explanation:
First, in order to get rid of the parenthesis, you need to multiply 2.5 with whatever is in the parenthesis.
Multiply 2.5 on each side of the equation like this:
(12.75 x 2.5) (24.50 x 2.5) =188.75
Once you're finished, you should get 61.25 and 31.875x =188.75
Now in order to find 'x' you will need to subtract 61.25 to each side of the equation like this:
61.25 - 61.25 = 0
188.75 - 61.25 = 127.5
So now your equation should look like this:
31.875x = 127.5
You have to divide 31.875 by each side now.
Once you divide them, your final answer should be 4.
so x = 4.

Sue has to cut her grandma's grass this weekend and wants to know exactly how much area she will be cutting. Calculate the area of the polygon. Be sure to show all your work and explain your answer.
Answer:
Six-sided polygon that includes two isosceles right triangles, one with height and base of 25 feet,
Total area = triangle 1 area + triangle 2 area + rectangle area= 312.5 + 32 + 280 = 624.5
Triangle1 area = height × base2
Triangle1 area = 25 × 252/ = 312.5
The other height and base of 8 feet,
Triangle 2 area = height × base2
Triangle 2 area = 8 × 8/2= 32
And one rectangle measuring 35 feet by 8 feet
Rectangle area = height × base
Rectangle area = 35 × 8 = 280
The area of the polygon is 624.50 ft².
The shapes in the polygon.The area of the polygon can be determined by adding the areas of the shapes in the polygon. The polygon is made up of two right triangles and a rectangle.
Area of a triangle = [tex]\frac{1}{2}[/tex] x base x height
Area of a rectangle = length x width
Area of the polygonArea of the rectangle
Width = 8 feet Length = 35 feetArea = 35 x 8 = 280 ft²
Area of the triangles
Area of the bigger triangle
Base = 33 ft - 8ft = 25 ftLength = 25 feetArea = 1/2 x 25 x 25 = 312.50 ft²
Area of the smaller triangle
Base = 43 ft - 35ft = 8 ftLength = 8Area = 1/2 x 8 x 8 = 32 ft²
Area of the polygon = 32 ft² + 312.50 ft² + 280 ft² = 624.50 ft²
