Answer:

the interest rate is $183.89 =~ $ 184

Step-by-step explanation:

In this question, Antuan deposited $2590 into a 3 year CD (Certificate of Deposit)  at an interest rate of 2.3% compounded quarterly. We need to find the interest account earned after 3 years.

Formula used will be :

[tex] Interest = P ( 1 + r/n) ^ n ^ t - P[/tex]

Where

P= Principal amount

r= interest rate (in decimals)

n= no of times the interest is compounded

t = no of years

Here we are subtracting P because we only need interest amount and not the future value.

Using this formula and finding the value will be:

P= $2590

r = 2.3 % or 0.023

n = 4

t = 3

[tex]Interest = 2590 * ( 1 - 0.023 / 4) ^ 4^ * ^ 3 - 2590[/tex]

[tex]Interest= 2590 (1.071) -2590\\Interest= 2773.89 - 2590\\Interest= 183.89[/tex]

So the interest rate is $183.89 =~ $ 184

Answer: 1,340 :)

Step-by-step explanation:

44*13= 572

96*8=768

572+768=1,340

Final answer:

The expression to calculate the total number of beads Lola used to make 13 bracelets and 8 necklaces is 13 × 44 + 8 × 96, with the total being 1340 beads.

Explanation:

To calculate the total number of beads Lola used to make 13 bracelets and 8 necklaces, we need to consider the number of beads used for one bracelet and one necklace individually. For one bracelet, Lola uses 44 beads, and for one necklace, she uses 96 beads.

Now, we add the two quantities together to get the total number of beads used:

572 beads (for bracelets) + 768 beads (for necklaces) = 1340 beads

Therefore, the expression to calculate the total number of beads used is 13 × 44 + 8 × 96.

Answer:

a = 102.05

b = 393.76

B = 93°

Step-by-step explanation:

The law of sines tells you ...

a/sin(A) = b/sin(B) = c/sin(C)

Since the sum of angles in a triangle is 180°, angle B must be ...

B = 180° -72° -15° = 93°

and the unknown sides must be ...

a = c/sin(C)·sin(A) = 375·sin(15°)/sin(72°) ≈ 102.05192

B = 93°

b = 375·sin(93°)/sin(72°) ≈ 393.75796

Step-by-step explanation:

The sum of all exterior angles of any polygon is always 360°.

To find the measure of one of these angles, divide 360° by the number of sides of the polygon

In this case, we have 7 sides, so

m = 360°/7 = 51.42°, or 51° rounded to the nearest degree

Answer:

  y ≈ 240.3 ft

Step-by-step explanation:

The mnemonic SOH CAH TOA reminds you that the relation between an angle and the sides adjacent and opposite is ...

  Tan = Opposite/Adjacent

In this triangle, the interior angle at lower right is the same as the one marked at upper left: 31°. y is the side opposite that angle, and 400 ft is the side adjacent. Then the relation is ...

  tan(31°) = y/(400 ft)

Multiplying by 400 ft gives ...

  y = (400 ft)·tan(31°) ≈ 240.3 ft

_____

The triangle interior angle at lower right and the angle marked 31° are "alternate interior angles" relative to the transversal marked x and the (parallel) horizontal lines in the figure. Alternate interior angles always have the same measure.

In geometry problems like this one, it means the angle of elevation (above the horizontal) is equal to the angle of depression (below the horizontal).

The distance from the center of the circle at (-1,2) to the point (2,-2) is 5 units and he did not calculate the distance correctly

The distance of a line between 2 points is always positive and given by the formula

Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )

The distance between A and B is D , and the distance D is

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

Given data ,

Let the first point be P = P ( -1 , 2 )

Let the second point be Q = Q ( 2 , -2 )

To find the distance from the center of the circle at (-1,2) to the point (2,-2), we can use the distance formula:

Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²

Distance D = √[(2 - (-1))² + (-2 - 2)²]

Distance D = √[3² + (-4)²]

D = √[9 + 16]

D = √25 = 5 units

Therefore, the point (2,-2) does lie on the circle.

However, Amit's work does not account for the fact that the center of the circle is not at the origin, but rather at (-1,2). This means that the distance from (-1,2) to (2,-2) must be used to determine if the point is on the circle, not the radius of the circle.

No, he should have used the center of the circle at (-1,2) to calculate the distance.

Answer:

1,080 Pennies

Step-by-step explanation:

This question is fairly simple, you just have to simplify it. You are starting at already half-full, so you can keep that 1/2 in mind. Then, she adds 360 pennies to get 5/6. If you convert 1/2 into 3/6, you can see that 360 pennies fills 2/6 of the piggy bank. So now you can solve two different ways. The first, you can take 360 and multiply it by 3 to get the amount that can fit in the piggy bank, because 2 * 3 = 6 and that would make it 6/6, or 1. The other way would be to divide 360 by 2 to get 1/6 of the piggy bank, or 180. Then you can multiply 180 by 6 to get the entire amount.

Hope this helped ^-^

By setting up a proportion, we can find that the total capacity of Amy's penny bank is 1440 pennies.

The subject of this problem is mathematics. We know that after adding 360 pennies, Amy's penny bank was 5/6 full. Before she added those pennies, it was 1/2 full. So, those 360 pennies represent the difference between 5/6 and 1/2 of the capacity of the penny bank.

To find the total capacity of the penny bank, we can set up a proportion as follows:

360 pennies / (5/6 - 1/2) = x pennies / 1

Therefore, x = 360 * (1 / (5/6 - 1/2))

By simplifying this, we find that the total capacity of Amy's penny bank is 1440 pennies.

Answer:

  50°

Step-by-step explanation:

As usual, the diagram is not drawn to scale.

The chord divides the circle into two arcs that have a sum of 360°. If we let "a" represent the measure of the smaller arc, then we have ...

  a + (a+160°) = 360°

  2a = 200° . . . . . . . . . . . subtract 160°

  a = 100°

The measure of the angle at A is 1/2 the measure of the subtended arc:

  acute ∠A = a/2 = (1/2)·100° = 50°

_____

Comment on this geometry

Consider a different inscribed angle, one with vertex V on the circle and subtending the same short arc subtended by chord AB. Then you know that the angle at V is half the measure of arc AB. This is still true as point V approaches (and becomes) point A on the circle. When V becomes A, segment VA becomes tangent line l, and you have the geometry shown here.

Answer:

the exterior angles of a polygon sum to 360

so the number of sides is 360/45

-PlushDna

Answer:

The difference in number of sides from one park to the next is 7

Step-by-step explanation:

For all polygon's the exterior angles combine to measure to 360 degrees. So to find the number of sides of each gazebo, we simply divide 360 by the measure of each individual exterior angle. We'll start with Logan Park.

360/22.5 = 16 sides

Now we can do the same with Cerro Park.

360/15.65 = 23 sides

Therefore, the difference in sides would be 7

Using Cramer's Rule, the value of x in the given system of linear equations is approximately -5.09.

To solve the system of linear equations using Cramer's Rule, we need to find the determinants of the coefficient matrix and the matrices obtained by replacing the corresponding column of the coefficient matrix with the constant matrix. Let's find the determinants:

Determinant of the coefficient matrix = |3 -4| = (3)(-6) - (4)(1) = -18 - 4 = -22

Determinant of the matrix obtained by replacing the x column = |-18 -4| = (-18)(-6) - (-4)(1) = 108 - (-4) = 112

Now, using Cramer's Rule:

x = Determinant of the matrix obtained by replacing the x column / Determinant of the coefficient matrix

x = 112 / -22 = -5.09

Therefore, the value of x in the given system of linear equations is approximately -5.09.
