A triangle has a base that is 4cm longer than its height.
a. Write a polynomial that represents the area of the triangle.
b. Find the area when the height is 8cm
Answer:
a) A =( x^2 -4x)/2
b) 16 cm^2
Step-by-step explanation:
Let the base of the triangle be x cm
since it is longer, then the height would be (x-4) cm
Mathematically, the area of a triangle is the product of the base and the height divided by 2
So, we have this as;
A = 1/2(x-4)x
A = x(x-4)/2
A = (x^2 - 4x)/2
A =( x^2 -4x)/2
To find the area, we only need to substitute 8 cm for x
we have this as;
A = (8^2 -4(8))/2
A = (64-32)/2 = 32/2 = 16 cm^2
We will begin by converting the word problem to relatable mathematical expression in the first part, in the second part, we will substitute for x and find the area which is 48cm^2
Given data
Let the height be x cm
and let the base be y cm
Going by the word problem statement "base that is 4cm longer than its height."
y = x+4
a. the polynomial expression for the area of the triangle is
We know that the area of triangle is given as
Area = 1/2*Base*Height
Area = 1/2*(x+4)*x
Area = 1/2*x^2+4x
Simplify
Area = x^2/2 + 2x
b. The Area when the height is 8cm
We will substitute x= 8cm
Area = (8)^2/2 + 2(8)
Area = 64/2 + 16
Area = 32+16
Area = 48 cm^2

The circle below has a radius of 10 inches. Find the area of Sector A and Sector C
Answer:
area of sector A = 47.97 in²
area of sector C = 109.03 in²
Step-by-step explanation:
area of full circle = πr² = (3.14)(10²) = 314 in²
area of sector A = (55/360)(314) = 47.97 in²
area of sector C = (314/2) - 47.97 = 109.03 in²

A cylinder made of lead has a height of 4 inches and a diameter of 2 inches. How heavy is the cylinder if lead weighs 0.4 pound per cubic inch? Round to the nearest tenth.
Answer:5.0
Step-by-step explanation:
The volume of a cylinder is [tex]\pi r^2h[/tex], since the radius is 1/2D, 2/2=1. Now, if [tex]\pi[/tex] is rounded to 3.14, the volume of the cylinder would be 1 x 1 x 3.14 x 4 = 12.56. Now, since there are 0.4 pound per cubic inch, 12.56 x 0.4 = 5.024. Rounded to tenth, the answer is 5.0 or 5.

a person's heart beats approximately 10^5 times each day. a person lives approximately 81 years. Work out an estimate for the number of times a person's heart beats in their lifetime
Answer:
29565x(10^5)
Step-by-step explanation:
heartbeat in 1 day=10^5.
we have 365 days in a year. it means that;
365x(10^5)=365x(10^5). this is heartbeat for 1 year.
then for 81 years,we multiply the value of 1 year heartbeat by 81.
=29565x(10^5).

Answer:
?
Step-by-step explanation:
Whats the question?
The proportionality constant if, A small smoothie will be 16 fluid ounces and sell for $3.52 is 22.
What is proportionality?When the corresponding elements of two numerical sequences, frequently experimental data, have a fixed ratio, this is referred to as the coefficient of proportionality, and the two sequences are said to be proportional or directly proportional.
Given:
A small smoothie will be 16 fluid ounces and sell for $3.52,
Convert the price of the smoothie in cents as shown below,
The price of a smoothie = 3.52 × 100 ($1 = 100 cents)
The price of a smoothie = 352 cents
Calculate the proportionality constant as shown below,
The proportional constant = Fluid / price
The proportional constant = 352 / 16
The proportional constant = 22
Thus, The proportional constant is 22.

could someone please answer #35 for me
Answer:
408
Step-by-step explanation:
Volume = length times width times height
So in this situation we can see that 17 is the length, 8 is the width, and 6 is the height
Knowing this information we can continue
If you think of a regular cube, you can split it diagonally and then it would be 2 triangles
So we can split the width, in halve which would be 4 and then apply the formula 4*6*17 and when you solve that you get 408 Now we have to split that in halve because remember it is a triangle and a triangle is halve of a square. Halve of 408 is 204.
If we repeat that prosses for the other side we will also get 204. Now we add 204+204 to get our answer 408.
Sorry is this was a little confusing but that's the best I can explain it.

how to find the circumference using 3.14
Answer:
c = 2 * 3.14 * r and c = 3.14 * d
Step-by-step explanation:
The formulas for the circumference of a circle are
c = 2πr and c = πd
where r is the radius and d is the diameter
using π = 3.14
the formulas become
c = 2 * 3.14 * r and c = 3.14 * d
Irina is watching a 3 hour movie on TV. The shaded part of the fraction model below represents the part of each hour that the movie is playing, and the unshaded part represents the time spent on commercials.
Answer:
3 * 5/6 = 15/6 hours
Step-by-step explanation:
From the figure attached :
The bar is divided into 6 equal parts ; with 5 of the sections being shaded and 1 left unshaded
The shaded represent the actual playing time
Unshaded portion = time spent in commercials
Using the model, the actual playing time of the movie excluding commercials :
(Shaded portion / total portion) * movie length
5 / 6 * 3 = (5*3) / 6 = 15/6
a set of two concentric circles is shown above. What is the area of the shaded portion above?

The polygons in each pair are similar. Solve for x.*
Answer:
X = 6
Step-by-step explanation:
Heights is 5x
Lengths is 6x
The solution for the x is 7 as per the concepts of similar polygons.
Given that the polygons in each pair are similar.
To find the value of x, we can set up a proportion between the corresponding side lengths of the two similar polygons.
We have the following proportion:
(6x - 7) / 42 = 25 / 30
To solve this proportion, we can cross-multiply:
30(6x - 7) = 42(25)
Simplifying further, we get,
180x - 210 = 1050
Next, we isolate the variable by adding 210 to both sides of the equation:
180x = 1260
Finally, we divide both sides by 180 to solve for x:
x = 1260 / 180
Simplifying:
x = 7
Therefore, the value of x is 7.
