. Simplify an expression for the perimeter of the equilateral triangle shown below.
Answer:
1.75×2-2
Step-by-step explanation:
look at the answer
The perimeter of the equilateral triangle with side length 1.75x - 2 is 5.25x - 6.
What is Perimeter?Perimeter of a geometrical shape is defined as the total boundary length. The perimeter of a shape can be calculated by adding the length of all the sides.
Perimeter of regular shape can be calculated by multiplying the length of the side with the total number of sides since a regular shape has all sides equal.
Here, we have an equilateral triangle with length of a side = 1.75x - 2.
Equilateral triangle is a regular shape, with all it's sides are equal.
Perimeter of an equilateral triangle with side length x is 3x.
Therefore,
Perimeter of this triangle = 3 ( 1.75x - 2 )
By distributive property, a (b + c) = ab + ac.
Perimeter = (3 × 1.75x) - (3 × 2)
= 5.25x - 6
Hence the perimeter of the equilateral triangle shown is 1.75x - 2.

Give the domain and range of each relationship. Determine whether or not each relationship is a function.
Answer:
Domain={2,5,8}
Range={1,3,6}
Function: YES
Step-by-step explanation:
The Domain of a Function
Is the set of values the input variable x takes.
Range of a Function
It's the set of values the output function takes when x moves into the function's domain.
A function is a relation between an input and an output set of values with the condition that every element in the domain relates only with one element in the range.
Following the definitions above, the domain of the relationship is the set of input values:
Domain={2,5,8}
The range is the set of output values:
Range={1,3,6}
Since each element in the input set is related only to one element in the range, the given relationship is a function.
Answers:
Domain={2,5,8}
Range={1,3,6}

For lunch with her friend, Kristionna is purchasing several side items that cost a total of $18, plus 2 sandwiches. The total cost of the meal is $32 and is represented by the equation 2x + 18 = 32. How much does each sandwich cost?
A) $14
B) $22
C) $7
D) $28
Answer:
C
Step-by-step explanation:
thee equation they give us is 2x + 18 = 32. Our goal is to isolate x.
First, subtract 18 from both sides to eliminate it.
2x + 18 = 32 ---> 2x + 18 - 18 = 32 - 18 ----> 2x = 14
Next, separate the 2 from the x by dividing it from both sides:
2x = 14 ----> 2x/2 = 14/2 ----> x = 7
By solving this equation, we find that x, or one sandwich, costs $7.

Answer:
a) T(t) = -13 +0.5t
b) D(t) = -4 -0.25t
c) 12 seconds
d) 7 feet
Step-by-step explanation:
a) The turtle starts at -13 feet and increases its elevation relative to the water's surface by 0.5 ft/second. After t seconds, the turtle will be 0.5t feet closer to the surface, so its depth will be ...
T(t) = -13 +0.5t
__
b) The diver starts at -4 feet and decreases their elevation relative to the water's surface by 0.35 ft/second. After t seconds, the diver will be 0.25t lower than the initial position, so their depth will be ...
D(t) = -4 -0.25t
__
c) The diver and turtle will be at the same depth when ...
T(t) = D(t)
-13 +0.50t = -4 -0.25t
0.75t = 9 . . . . . . . . . . . . add 13+0.25t
t = 12 . . . . . . . . . . . . . . . divide by 0.75
The diver and turtle will be at the same depth after 12 seconds.
__
d) That depth will be ...
T(12) = -13 +0.5(12) = -13 +6 = -7
The diver and turtle meet at a depth of 7 feet.

You want to measure the length of a ribbon in inches. You only have a centimeter ruler. The length of the ribbon is 15 cm. Is the ribbon longer or shorter than 15 inches? How many inches long is it?
Answer:
Shorter than 15IN, 5.9 or 6 inches
Hope this helps:)
Step-by-step explanation:
The ribbon is shorter than 15 inches, and its length is approximately 5.91 inches.
Given that a ribbon has a length of 15 cm, we need to calculate the length in inches,
To determine the length of the ribbon in inches, we need to convert the length from centimeters to inches.
To convert centimeters to inches, we can use the conversion factor 1 inch = 2.54 centimeters.
The length of the ribbon is 15 centimeters. To convert this to inches, we divide 15 by 2.54:
15 cm / 2.54 cm/inch = 5.91 inches (rounded to two decimal places).
So, the ribbon is shorter than 15 inches.
The ribbon is approximately 5.91 inches long.

There were 1,265 people at a boat show. After 1/5 of the adults and 1/3 of the children left, there was an equal number of children and adults at the show. how many people left the show?
Answer:
I think the answer is 171.
Step-by-step explanation:
Find the total amount of people that left the show. Convert 1/5 and 1/3 into fractions with common denominators. This makes 3/15 and 5/15. Add the two together and get 8/15. Divide 8 by 15 to find the percent of people that left. About 53%. Multiply 1,265 by .53 and you get 170.45 You can't have 45/100 of a person to do the rounding up to get 171. Check you work by subtracting 171 from 1,265 and get 1094. If you divide this by two you get 547. (547 kids, and 547 adults)

Mr. Jamison will stain the deck in his backyard, the deck has an area of 752.4 sqaure feet. If the deck is 33 feet long how wide is it? Justify your procedure.
answer:The width of the deck is 22.8 feet.
Step-by-step explanation:
Since we have given that
Area of the deck = 752.4 square feet
Length of deck = 33 feet
Let width of deck be 'x'.
Since Deck is in the shape of rectangle.
As we know the formula for "Area of rectangle ":
\begin{gathered}Area=Length\times width\\\\752.4=33\times x\\\\\dfrac{752.4}{33}=x\\\\22.8=x\end{gathered}
Area=Length×width
752.4=33×x
33
752.4
=x
22.8=x
Hence, the width of the deck is 22.8 feet.
