The angle A for the given triangle will be 57°.
What is a triangle's definition?
In geometry, triangles have three sides and three vertices. This two-dimensional figure has three straight sides. A triangle is a three-sided polygon. The total of three triangle angles equals 180°. The triangle is enclosed by only one plane. Triangles are classified into three different categories based on their sides.
Scalene Triangle - The length of each side varies.
Isosceles Triangle - A triangle having two equal-length sides and one that is not.
Equilateral Triangle - A triangle with three sides of equal length.
Now,
let the right angle is at B
then AB=Base=7 and BC=perpendicular=11
then Tan A=B/P=11/7
Tan A=1.57
∠A=57°
hence,
The angle A for the given triangle will be 57°.

Answers
The expected number of times for the probability of getting heads after flipping a two coins is equal to 1/4.
Number of coins flips at the same time = 2 coins
Coins are independent of each other
Either both the times heads , one time head or both the times tails.
Sample Space of coin 1 and coin 2 = { H, T}
Probability of each outcome = 1/2
x : 0 1
p(x) : 1 / 2 1/2
Expected value of getting heads for each coin
E(X) = ∑x p(x)
X₁ and X₂ are two possibility for each coin to get head
Both are independent of each other.
E(X₁) = 1/2
E(X₂ ) = 1/2
E(X₁ × X₂) = E(X₁) × E(X₂ )
= ( 1/2) × ( 1/2)
= 1/4
Therefore, the expected number of times to get probability of at least one heads is equal to 1/4.

10. A pipe whose diameter measures 1 1/4 inches should have less threads per inch than a pipe with a diameter of _______ inch.
A. 3
B. 1/2
C. 1
D. 11/2
Answers
A pipe whose diameter measures 1 1/4 inches should have less threads per inch than a pipe with a diameter of 11/2 inch. So, the correct answer is (D).
To determine the correct answer, we need to compare the diameters of the two pipes and understand the relationship between pipe diameter and threads per inch.
The number of threads per inch generally decreases as the pipe diameter increases. This means that a larger pipe diameter will have fewer threads per inch compared to a smaller pipe diameter.
Given that the first pipe has a diameter of 1 1/4 inches, we need to find the pipe diameter from the options that is larger than 1 1/4 inches.
The option that meets this requirement is D. 11/2. This represents a pipe diameter of 1 1/2 inches. Therefore, a pipe with a diameter of 1 1/2 inches should have fewer threads per inch than a pipe with a diameter of 1 1/4 inches. Therefore, the correct answer is D. 11/2.

Can you help me find the scale factor and center of the dilation, you don’t need to go into too much details because I basically got it down
Answers
Looking at the graph, we can say that the center of dilation is at point I since this point doesn't change.
We need to find the ratio of the distances between the new and the old.
For the new side, let's choose H'(-1, 6) and I'(3, 8)
Using distance formula :
\(\begin{gathered} d=\sqrt[]{(x_2-x_1)^2+(y_2-y_1)^2} \\ d=\sqrt[]{(3+1)^2+(8-6)^2} \\ d=\sqrt[]{20} \end{gathered}\)And for the old or original side H(-3, 5) and I(3, 8)

Please help!! I’ve been stuck on this for days!!! Finding the common difference and equation for the following arithmetic sequence! Thanks
Answers
The common difference is d = -4, since
-32 - (-28) = -4
-36 - (-32) = -4
-40 - (-36) = -4
and so on.
In the arithmetic sequence starting with \(a_1=-28\) and common difference -4, the next term is obtained by adding -4 to the previous one:
\(a_1 =-28\)
\(a_2 = a_1 + d = -28 - 4 = -32\)
\(a_3 = a_2 + d = a_1+2d = -28-4\times2 = -36\)
\(a_4 = a_3 + d = a_1+3d = -28-4\times3 = -40\)
and so on, up the n-th term
\(a_n = a_{n-1}+d = a_1+(n-1)d = \boxed{-28-4(n-1)}\)

We have,
3.
An equilateral triangle.
Where all three angles and all three sides are equal and the angle is 60°.
Now,
16 + y = 46
y = 46 - 16
y = 30
And,
180 - 80° = 100°
The sum of the angles must be 180°.
x + 100 + 60 = 180
x = 180 - 160
x = 20°
4.
We have an equilateral triangle and an isosceles triangle.
All the angles in the equilateral triangle are 60°.
The two angles opposite to the equal sides of the isosceles triangle are equal.
So,
5y = 20
y = 4
And,
In the isosceles triangle.
The straight angle.
60 + angle = 180
angle = 180 - 60
angle = 120.
Now,
The sum of the angles of the isosceles triangle = 180.

What is simple interest?We know simple interest (SI) is given by SI = (p×r×t)/100, where
p = principle, r = rate in percentage, and t = time in years.
Given, On February 1, the balance in your account is $516.81 and the bank pays 6.25% interest.
Now, from February 1 to July 1 is 5 months or 5/12 years.
∴ SI earned is = (561.81×6.25×5/12)/100.
= $14.6
On July 1, you deposit $310.90 so the current balance is
$(516.81 + 14.6 + 310.90) = $842.31.
From july 1 to november 1 it is 4 months or 4/12 = 1/3 years.
∴ SI = (842.31×6.25×1/3)/100.
= $17.5.
The amount on November 1 is $(842.31 + 17.5) = $859.81

Step-by-step explanation:
Compound interest formula is expressed as;
A = P(1+r)^n
P is the amount invested = $6000
r is the rate = 6% = 0.06
t is the time = 6yrs
A is the compound amount
A = 6000(1+0.06)^6
A = 6000(1.06)^6
A = 6000(1.4185)
A = 8,511.1147
Hence the compound amount to 4dp is $8,511.1147

s1 = 5
s2 = s1 × -2 = 5×-2 = -10
s3 = s2 × -2 = -10 × -2 = 20

now, we could do all that manually.
but there is also a formula for geometric sequence.
in fact, there are 2 - one for finite and one for infinite sequences.
and I was not completely honest, each of these 2 had some sub-forms depending on the size of the multiplier or ratio.
since we need the sum of the first 5 terms, which of the 2 do you think we need ?
of course, finite, because 5 is a normal number we can "touch". it is not infinity.
so, the formulas for finite sums of geometric sequences are :
if |r| < 1, Sn = a(1 - r^n)/(1 - r)
if |r| > 1, Sn = a(r^n - 1)/(r - 1)
if r = 1, Sn = na
if r = -1, then Sn = a or 0 depending on if n is odd or even.
the sequence is in general
s1 = a
sn = sn-1 × r
in our case a = 5, r = -2.
so, what form of the formula do we need ?
|-2| = 2, and 2 > 1, so ...

We can start with θ = 0, and calculate the radius for different values of θ. (π/6, π/3, π/4 and so on. Then, you can join the points.
The equation for radius will be:
\(\begin{gathered} r^2=16\cos 2\theta \\ r=\sqrt[]{16\cos2\theta} \\ r=4\cdot\sqrt[]{\cos2\theta} \end{gathered}\)\(\begin{gathered} \text{for }\theta=0 \\ r=4\cdot\sqrt[]{\cos2\cdot0} \\ r=4\cdot\sqrt[]{\cos0} \\ r=4\cdot\sqrt[]{1} \\ r=4 \end{gathered}\)Then, in the line of θ = 0, you draw a point in the fourth circle.
Then, we get the following table of values:

Note that we can't evaluate angles whose cosine is negative (angles in quadrants 2 and 3) since we would be trying to calculate the square root of a negative number, which does not exist among real numbers. Then, we will evaluate angles in the first quadrant (already done) and the 4th quadrant.

The length of a rectangle is twice its width. Find its lenght and width, if its perimeter is 7 1/3 cm.
Answers
The length of the rectangle is twice its width. If its perimeter is 7 1/3 cm, its length will be 22/9 cm, and the width is 11/9 cm.
Let's assume the width of the rectangle is "b" cm.
According to the given information, the length of the rectangle is twice its width, so the length would be "2b" cm.
The formula for the perimeter of a rectangle is given by:
Perimeter = 2 * (length + width)
Substituting the given perimeter value, we have:
7 1/3 cm = 2 * (2b + b)
To simplify the calculation, let's convert 7 1/3 to an improper fraction:
7 1/3 = (3*7 + 1)/3 = 22/3
Rewriting the equation:
22/3 = 2 * (3b)
Simplifying further:
22/3 = 6b
To solve for "b," we can divide both sides by 6:
b = (22/3) / 6 = 22/18 = 11/9 cm
Therefore, the width of the rectangle is 11/9 cm.
To find the length, we can substitute the width back into the equation:
Length = 2b = 2 * (11/9) = 22/9 cm
So, the length of the rectangle is 22/9 cm, and the width is 11/9 cm.
