Find the perimeter of the above shape to the nearest whole number take pi as 22/7
The unshown part is 16cm
Answer:
60.
Step-by-step explanation:
I can't see the question above this and what information it gives, but If I'm not mistaken, that shape is a rectangle, so regardless of whether there's a piece of the last side missing, the sides across from each other are congruent in size.
So if the top is 14, then the bottom is 14, and since the left side is 16, then the side missing a piece adds up to 16.
(14*2) + (16*2) =
28 + 32 = 60.

[tex] h(t) = 8 + 40.8t -{16t}^{2} [/tex]
at what height is the ball after 2 seconds?
Step-by-step explanation:
When t = 2,
h(2) = 8 + 40.8(2) - 16(2)² = 8 + 81.6 - 64 = 25.6
Therefore the height after 2 sec is 25.6.
Answer:
[tex]h(t) = 8 + 40.8t - {16t}^{2} \\ h(2) = 8 + 40.8(2) - 16 {(2)}^{2} \\ = 8+81.6 - 64 \\ = 89.6 - 64 = \boxed{25.6}[/tex]
After 2 seconds the ball will be at the height of 25.6 unit.

A cylindrical water tank has a radius of 14.5 feet and a height of 7.5 feet. Which value is the best estimate of the volume of the water tank? Round your answer to the nearest tenth of a foot.
Answer:
C= 2π14.5
C= 91.1061869
91.1061869 X 7.5 = 683.296402
A of a circle = πr squared
as the are two circles to a cylinder 2πr squared

Take a to be 3.142 and give your answer to 1 decimal place.
9m
Answer:
28.3 (explaination below)! :)
Step-by-step explanation:
Use the formula for cicrumfrence: C=2πr
Radius can be found by splitting the given number in half, (unless you were given the radius already, then you'd just multiply by 2).
Plug in our numbers. C= 2π4.5
Then, multiply.
You'd get 28.27433388230814.
Rounding to the first decimal place, you'd have a final answer of 28.3.
Hope this helps!

You have 19.3 ounces of juice in a cup and pour 33.5 more ounces in the same cup. How many total ounces of juice are in the cup now?
Answer: There is 52.8 ounces of the juice in the cup now.
Step-by-step explanation:
We are given that,
The quantity of juice you initially have = 19.3 ounces
You added 33.5 ounces more to the cup.
Then, By using the addition operation, the total quantity of juice in the cup will be (Juice you initially had) + (additional amount)
i.e. The total quantity of juice in the cup= 19.3 + 33.5 ounces
The total quantity of juice in the cup= 52.8 ounces
Hence, there is 52.8 ounces of the juice in the cup now.

What are Polynomials?Polynomials are mathematical expressions which consist of one or more terms involving variables and coefficients connected with operations like multiplication, subtraction, addition and natural number powers of variables.
Given is a cubic polynomial expression.
Given is x³ - 1.
We have to factorize it.
x³ - 1 = x³ - 1³
We have the algebraic expression identity that,
a³ - b³ = (a - b) (a² + ab + b²)
Using the expression, we get,
x³ - 1³ = (x - 1) (x² + x + 1²)
= (x - 1) (x² + x + 1)
Hence the correct form is option C.

In the figure above, what is the area of right
triangle QRS?
The area of right triangle QRS will be;
⇒ The area of triangle = 20
What is mean by Triangle?A triangle is a three sided polygon, which has three vertices and three angles which has the sum 180 degrees.
Given that;
In ΔQRS;
Base = x
Height = 2x
Hypotenuse = 10
Now,
Since, The triangle is a right triangle.
Hence, The triangle QRS satisfy the condition of Pythagoras theorem.
So, We get;
⇒ Hypotenuse² = Base² + Height²
⇒ 10² = x² + (2x)²
⇒ 100 = x² + 4x²
⇒ 100 = 5x²
⇒ x² = 20
⇒ x = √20
So, The Height of triangle = 2√20
And, The Base of the triangle = √20
We know that;
⇒ The area of triangle = 1/2 × Height × Base
⇒ The area of triangle = 1/2 × 2√20 × √20
⇒ The area of triangle = 20
Thus, The area of right triangle QRS = 20
