Answer:

Lowest possible score is 59.865 and you can still maintain an 80 by the end.

Step-by-step explanation:

Answer:

To find the amount of interest earned by depositing $220 into an account that earns 4% interest for one year, we can use the simple interest formula:

Interest = Principal * Rate * Time

Where:

Principal = $220 (the amount deposited)

Rate = 4% (expressed as a decimal, so 0.04)

Time = 1 year

Plugging in these values, we get:

Interest = $220 * 0.04 * 1

Interest = $8.80

Therefore, the amount of interest earned by depositing $220 into an account that earns 4% interest for one year is $8.80.

Answer:

How to find angle in triangle ?

To find the measure of an angle in a triangle, you need to know the measures of the other two angles in the triangle. Since the sum of all angles in a triangle is always 180 degrees, you can use this fact to calculate the measure of the third angle.

There are a few different methods we can use to find the measure of an angle in a triangle:

Subtract the measures of the other two angles from 180 degrees. This works for any triangle, regardless of its shape or size.

Use the fact that the angles opposite equal sides of a triangle are equal. This is known as the "angle-side-angle" (ASA) theorem. For example, if you know the lengths of two sides of a triangle and the angle between them, you can use the Law of Cosines to find the third side and then use the Law of Sines to find the opposite angle.

Use the fact that the angles in a right triangle are related by the Pythagorean Theorem. If you know the lengths of two sides of a right triangle, you can use the Pythagorean Theorem to find the length of the third side, and then use trigonometric ratios (sine, cosine, tangent) to find the measure of the angle opposite the known side.

Use the fact that the angles in an equilateral triangle are all equal. If you know that a triangle is equilateral, you can simply divide 180 degrees by 3 to find the measure of each angle.

In a triangle, the sum of all angles is always 180 degrees. Therefore, we can use this fact to find the measure of angle Y:

angle Z + angle X + angle Y = 180 degrees

Substituting the given values:

113 degrees + 28 degrees + angle Y = 180 degrees

Simplifying and solving for angle Y:

141 degrees + angle Y = 180 degrees

angle Y = 180 degrees - 141 degrees

angle Y = 39 degrees

Therefore, angle Y measures 39 degrees.

    |<---- 44 cm ---->|

    |                  |

After x is cut off each rod, the remaining lengths can be arranged to form a right triangle, as shown below:

               +---------(44-x)--------+

               |                        |

               |                        |

   +-----------+------------------------+

               |         x              |

b) To model the situation, we can use the Pythagorean theorem, which states that in a right triangle, the sum of the squares of the two shorter sides is equal to the square of the hypotenuse. In this case, we have:

(20-x)^2 + (41-x)^2 = (44-x)^2

c) To find the length that is cut off, we can solve the equation from part (b) for x. First, we can simplify the equation by expanding the squares:

400 - 40x + x^2 + 1681 - 82x + x^2 = 1936 - 88x + x^2

Simplifying further, we get:

2x^2 - 18x - 855 = 0

We can solve for x by using the quadratic formula:

x = [18 ± sqrt(18^2 + 4(2)(855))] / (2(2))

x = [18 ± sqrt(7404)] / 4

x ≈ 16.98 or x ≈ -24.98

Since x represents a length that is cut off each rod, it must be positive. Therefore, we can discard the negative solution and conclude that the length that is cut off is approximately 16.98 cm.

d) Using the length that is cut off, we can find the dimensions of the right triangle by substituting x = 16.98 into the expressions for the remaining lengths. We get:

(20 - 16.98) = 3.02 cm

(41 - 16.98) = 24.02 cm

(44 - 16.98) = 27.02 cm

Therefore, the dimensions of the right triangle are 3.02 cm, 24.02 cm, and 27.02 cm.

Answer:

Sandra walked longer by 240 - 230 = 10 meters.

Step-by-step explanation:

To find out who walked longer and by how much, we need to calculate the distance walked by each person.

For Jay who walked two rounds around Ace Park, the distance walked is:

Distance = 2 × (length + width) = 2 × (75 + 40) = 230 meters

For Sandra who walked two rounds around Lewis Park, the distance walked is:

Distance = 2 × (length + width) = 2 × (90 + 30) = 240 meters

Therefore, Sandra walked longer by 240 - 230 = 10 meters.

Using the given formula [A = 1/2s²], we know that the area of one of the triangles is (C) 50 cm².

A patch's area on a surface determines how big it is.

Whereas a plane region or area refers to the area of a shape or planar lamina, a surface region or plane area refers to the area of an open surface or the boundary of a three-dimensional object.

A plane figure's area is the space that its perimeter encompasses.

The area of a closed figure is the total number of unit squares covering its surface.

The area is measured in square units like cm² and m².

So, we know that the area of the triangle is now:

A = 1/2s²

The side of the square is: 10 cm

Then, the area of the one triangle is:

A = 1/2s²

A = 1/2*10²

A = 1/2*100

A = 50 cm²

Therefore, using the given formula [A = 1/2s²], we know that the area of one of the triangles is (C) 50 cm².

The odds in favor of drawing a 7 are 1 to 12.

What is probability?

Probability is a measure of the likelihood or chance of an event occurring. It is expressed as a number between 0 and 1, where 0 represents an impossible event and 1 represents a certain event.

There are four 7s in a deck of 52 cards, so the probability of drawing a 7 is 4/52, which simplifies to 1/13. The odds in favor of drawing a 7 are the ratio of the probability of drawing a 7 to the probability of not drawing a 7, which is:

(1/13) : (12/13

We can simplify this ratio by dividing both terms by the greatest common factor, which is 1:

Answer:

the average velocity of the ball on the interval [1, 3/2] is -808 ft/s.

Step-by-step explanation:

The height of the ball at time t is given by the formula:

s(t) = -16t^2 + 50t + 1200

We need to find the average velocity of the ball on the interval [1, 3/2]. The average velocity is defined as the change in position divided by the change in time, or:

average velocity = (s(3/2) - s(1)) / (3/2 - 1)

Substituting the formula for s(t), we get:

average velocity = ((-16(3/2)^2 + 50(3/2) + 1200) - (-16(1)^2 + 50(1) + 1200)) / (3/2 - 1)

Simplifying and solving for the average velocity, we get:

average velocity = (430 - 1234) / (1/2) = -808 ft/s

Therefore, the average velocity of the ball on the interval [1, 3/2] is -808 ft/s.

Considering the expression of a line, an equation for the line best fit to the points (0, 60) and (4, 90) is y=7.5x +60.

A linear equation o line can be expressed in the form y = mx + b

where

Knowing two points (x₁, y₁) and (x₂, y₂), the slope m can be calculated using:

m= (y₂ - y₁)÷ (x₂ - x₁)

Substituting the value of the slope m and the value of one of the points, the value of the ordinate to the origin b can be obtained.

In this case, being (x₁, y₁)= (0, 60) and (x₂, y₂)= (4, 90), the slope can be calculated as:

m= (90 - 60)÷ (4-0)

m= 30÷ 4

m= 7.5

Considering point 1 and the slope m, you obtain:

60= 7.5×0 + b

60= 0 +b

60= b

Let X be the number of trials (free throws) until the first success (a made free throw). Since we want to know the probability of missing the first free throw and making the second one, we want to find P(X = 2).

Using the geometric distribution formula, we have:

P(X = 2) = (1 - p)^(k-1) * p

p is the probability of success (making a free throw)

k is the number of trials (2 in this case), and (1 - p)^(k-1) is the probability of having k-1 failures (missing the first free throw) followed by one success (making the second free throw).

As a result, when the camera and the rocket are 4255 feet apart, the rate  trigonometry of change in the angle of elevation after launch is roughly -0.15807 radians/foot.

Trigonometry is the field of mathematics that explores the connection between triangle side lengths and angles. The issue first originated in the Hellenistic era, during the third century BC, as a result of the use of geometry in astronomical investigations. The subject of mathematics known as exact techniques is concerned with certain trigonometric functions and their possible applications in calculations. Trigonometry contains six commonly used trigonometric functions. Their separate names and acronyms are sine, cosine, tangent, cotangent, secant, and cosecant (csc). Trigonometry is the study of triangle characteristics, particularly those of right triangles. As a result, geometry is the study of the properties of all geometric forms.

Where is the camera's angle of elevation and c is the rocket's height above ground level.

We may express the angle of elevation using the given formula as:

r θ = tan⁻¹(c/2000)

c2 + x2 = d2, where d = 4255 ft 2c(dc/dx) + 2x = 0, and dc/dx = -x/c.

When we multiply c by 2000 tan() and x by (d2 - 20002) (since x is the horizontal distance between the camera and the rocket), we get: dc/dx = -(d2 - 20002) / (2000 tan())

tan1(0.02d/2000) = tan1(d/100000)

dc/dx = -(d2 - 20002) / (2000 tan(tan1(d/100000)) = -(d2 - 20002) / (2000 tan(tan1(d/100000)) = -0.005(d2 - 20002) / d

dc/dx = -0.005(42552 - 20002) / 4255 -0.15807 radians per foot

Answer: Let's begin by assigning variables to represent the dimensions of the room. Let's use "l" to represent the length and "w" to represent the width.

We know that the length of the room is 5 feet longer than twice the width, so we can write an equation:

l = 2w + 5

We also know that the perimeter of the room is 178 feet. The formula for the perimeter of a rectangle is:

perimeter = 2(length + width)

Substituting the equation we found for the length, we get:

178 = 2(2w+5 + w)

Simplifying, we can combine like terms and solve for w:

178 = 2(3w+5)

89 = 3w+5

84 = 3w

w = 28

Now that we know the width is 28 feet, we can use the equation for the length to find the length:

l = 2w+5 = 2(28)+5 = 61

Therefore, the dimensions of the room are 61 feet by 28 feet.
