If there were 1/9 blue eyes, the remaining are the ones without blue eyes.
Therefore 8/9 is the remaining amount.
Answer:
Area of the triangle is 121 cm²
Step-by-step explanation:
To solve this, we will follow the steps below;
We will first find the height of the triangle, from the diagram below:
opposite = h where h is the height of the triangle
adjacent = 7
Ф=68°
Using trig.ratio
tan Ф = opposite/adjacent
tan 68° = h/7
h = 7 tan 68° = 17.33
height of the triangle =17.33 cm
From the question, base(b) = 14 cm
Area of a triangle = 1/2 × b × h
=1/2×14×17.33
=121.31
≈ 121 cm²
Area of the triangle is 121 cm²
Answer: B) BC=4 in.
Step-by-step explanation:
Given: In △ABC , AB=4 inch ,AC=4 in. , and m∠A=60°
⇒ AB=AC= 4 inches
⇒ △ABC is an isosceles triangle.
⇒ m∠A=60°=m∠B [angles opposite to the equal sides of a triangle are equal]
Now by angle sum property,
m∠A+m∠B+m∠C=180°
⇒60°+60°+m∠C=180°
⇒ m∠C=180°-120°
⇒ m∠C=60°
⇒ △ABC is an equilateral triangle.
⇒ BC= 4 inches [sides of an equilateral triangles are equal]
⇒ B is the right answer.
Answer:
Option C) is correct
That is the given arithmetic sequence represents the recursive formula is f(n)=f(n-1)+(-5)
Step-by-step explanation:
The given arithmetic sequence is
Let f(1)=94,f(2)=89,f(3)=84,...
To find the common difference d :
,
Therefore d=-5
,
Therefore d=-5
Therefore the common difference d=-5
check the recursive formula which represents the given arithmetic sequence
Put n=2 and d=-5 in we get
Therefore f(2)=89
Put n=3 and d=-5 in we get
Therefore f(3)=84
and so on
Therefore the recursive formula where d=-5
Therefore the recursive formula represents the given arithmetic sequence
A rhombus is considered a parallelogram since a parallelogram is defined as any figure having four sides with opposite sides parallel. <span>On a basic parallelogram, opposite angles are congruent. Therefore, the correct answer to the given statement above would be TRUE. Hope this answer helps. </span>
