The required vertices of the triangle C'D'E' are (-8, 1), (-6, 5), and (-2, 4) respectively.

Given that,
Triangle CDE is reflected over the x-axis. What are the vertices of triangleC'D'E' is to be determined.

The triangle is a geometric shape that includes 3 sides and the sum of the interior angle should not be greater than 180°

Here,

The coordinates of vertices  C, D, and E are (-8, -1), (-6, -5), and (-2, -4) respectively.

For the reflection across the x-axis is given as,

(x , y) = (x  -y)

3.7261×10¹⁵ seconds  is the time it would take you to empty the lake

Given that:

Lake Eric can hold 116 cubic miles of water

One cup has a diameter of 2 and 3/4 inches and a height of 4 inches

Volume of cone cup = 1/3 πr²h

Volume of cone cup = 1/3×π×(11/8)²×4 = 7.92 cubic inches

Volume of Lake Erie = 116 cubic miles

To convert to cubic inches multiply by 2.544×10¹⁴:

Volume of Lake Erie = 116×2.544×10¹⁴ = 2.95104×10¹⁶ cubic inches

Time taken = 2.95104×10¹⁶ / 7.92 = 3.7261×10¹⁵ seconds

Since you are missing a part to the sum, you use subtraction to find the missing part.

The number of dark chocolate AJ sold is 75

Simultaneous equations are two or more algebraic equations that share variables e.g. m and d . They are called simultaneous equations because the equations are solved at the same time.

If the number of Milk chocolate candy is m and the number of dark chocolate candy is d, then

m+d= 200 equation 1

3m+4d= 675 equation 2

to eliminate m we multiply both equations by 3

3m+3d= 600 equation 3

3m+ 4d=675 equation 4

subtract equation 3 from 4

d = 675-600

d= 75

Therefore the number of dark chocolate candy AJ sold is 75.

The area of the composite figure is 242in² as per the given information in the figure.

Rectangulus, a combination of the Latin words rectus (as an adjective, right, appropriate), and angulus, is where we get the word rectangle (angle).

A crossed rectangle is a crossed (self-intersecting) quadrilateral made up of two opposing sides and the two diagonals of a rectangle[4] (therefore only two sides are parallel). It is a specific case of an antiparallelogram with angles that are not all equal and right angles, even though opposite angles are. Other geometries, including spherical, elliptic, and hyperbolic,  with opposite sides of equal length and equal angles that are not right angles.

Area =Area of the down rectangle+ Area of the up rectangle+2×Area of the triangle

Area= (7×24)+(4×13)+2×(1/2)×b×4

Let, 13+2x=24

Here, x=b

So, 2b=11

b=11/2

Area= 168+52+4(11/2)

Area=168+52+22

Area=242in²

Therefore, the area of the composite figure is 242in².

You will have $3276.44 after 4 years if you deposit $3,000 at an annual interest rate of 2.5%, compounded continuously.

What is continuous compound interest?

In theory, continuously compounded interest means that an account balance is constantly earning interest, as well as refeeding that interest back into the balance so that it, too, earns interest.

The formula for continuously compounded interest is:

              [tex]A = P * e^{rt}[/tex]

where:

A is the ending balance (the amount you will have after 4 years)

P is the principal (the initial amount you deposited, in this case $3,000)

r is the interest rate (2.5% per year, or 0.025)

t is the time in years (4 years)

Plugging these values into the formula, we get:

            [tex]A = $3,000 * e^{(0.025 * 4)}[/tex]

Calculating this gives us an ending balance of $3,276.44.

Hence, you will have $3276.44 after 4 years if you deposit $3,000 at an annual interest rate of 2.5%, compounded continuously.

What is an Inequality Equation?

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

In an inequality, the two expressions are not necessarily equal which is indicated by the symbols: >, <, ≤ or ≥.

Given data ,

Let the first inequality equation be represented as P

The value of P is

-4 ≤ x ≤ 6

Let the second inequality equation be represented as Q

The value of Q is

2 ≤ y ≤ 8

Now , the smallest value of inequality P is = -4

The largest value of inequality P is = 6

And , the smallest value of inequality Q is = 2

The largest value of inequality Q is = 8

a)

Let the smallest possible value of x - y be = A

The value of x - y is calculated as

The smallest value of P - smallest value of Q

Substituting the values in the equation , we get

A = -4 - 2

A = -6

Therefore ,  The smallest possible value of x - y is A = -6

b)

Let the largest possible value of 2x / y be = B

The value of 2x/y is calculated as

Largest value of x goes in numerator and smallest value of y goes in denominator to get the largest value of 2x/y

So , substituting the values in the equation , we get

B = ( 2 x 6 ) / 2

B = 12 / 2

B = 6

Therefore , The largest possible value of 2x / y is B = 6

c)

Let the largest possible values of x² + y² be = C

The value of x² + y²  is calculated as

The largest value of x squared + the largest value of y squared

Substituting the values in the equation , we get

C = 6² + 8²

C = 36 + 64

C = 100

Therefore , The largest possible value of x² + y² is C = 100

Hence , The solutions are

a) The smallest possible value of x - y is A = -6

b) The largest possible value of 2x / y is B = 6

c) The largest possible value of x² + y² is C = 100

The measure of the third angle = 105°.

What is angles?

An angle is a figure in Euclidean geometry made up of two rays that share a common terminal and are referred to as the angle's sides and vertices, respectively. Angles created by two rays are on the plane where the rays are located. The meeting of two planes also creates angles. We refer to these as dihedral angles.

The sum of the angles in a triangle is :

A° + B° + C° = 180°

Where A, B and C are the three angles in a triangle.

Hence, if two of the angles are given as : 55° and 20°

The measure of the third angle will be :

Let the measure of the third angle = C

(55 + 25 + C) = 180°

180° - (55° + 20°)

180° - 75° = 105°

Answer:

correct answer is D) $1.94.

Step-by-step explanation:

To solve this problem, we first need to calculate the total cost of the candy bars and the sodas. The candy bars cost $0.84 each, so 3 candy bars cost 3*$0.84=$2.52. The sodas cost $1.80 each, so 2 sodas cost 2*$1.80=$3.60. The total cost of the candy bars and sodas is $2.52+$3.60=$6.12.

Since you are going to split the cost with your friend, you will pay for half, which is $6.12/2=$3.06. You pay for your half with a five dollar bill, so you will receive $5-$3.06=$1.94 in change.

I hope it helps, let me know if you have another questions.

Answer:

Step-by-step explanation:

First, we need to find the total cost of the candy bars by multiplying the number of candy bars by the price per candy bar: 3 candy bars * $0.84/candy bar = $3*0.84=2.52Next, we need to find the total cost of the sodas by multiplying the number of sodas by the price per soda: 2 sodas * $1.80/soda = $2*1.8=3.60Then, we need to add the cost of the candy bars and the sodas to find the total cost: $2.52 + $3.60 = $<<2.52+3.6=6.12>>6.12Since you are paying for half of the total cost, you need to pay half of $6.12, or $3.06.If you pay for your half with a five dollar bill, you will receive $5 - $3.06 = $5-3.06=1.94 in change.

The area is 120 [tex]cm^{2}[/tex].

Area is the size of a two-dimensional surface, usually expressed in square units, such as square feet or square meters. It is the amount of two-dimensional space enclosed within a given set of boundaries. Area can be calculated for various shapes, including squares, rectangles, triangles, circles, and more complex shapes. Area is also a measure of the amount of space an object occupies. In mathematics, area is used to measure the size of a shape or region in a plane. It can also be used to calculate the size of a figure, such as the area of a triangle, or to measure the area of an enclosed space, such as a garden or a room.

Given:

AB = CD = 8cm

AD = BC = 12cm

EF = DH = 4cm

So, the required area is A = Area (ABCEFD) = Area (ABCD) + Area (CEFD)

Area of ABCD = Area (ABCD) = AB × BC

⇒ 12 × 8 = 96 [tex]cm^{2}[/tex]

Area of CEFD = Area (CEFD) = 0.5 (CD + EF) × HD

⇒ 0.5 × (8 + 4) × 4 = 24[tex]cm^{2}[/tex]

Now, the required area is

⇒ A = 96 [tex]cm^{2}[/tex] + 24 [tex]cm^{2}[/tex] = 120 [tex]cm^{2}[/tex]

Hence, the required area of the figure is 120 [tex]cm^{2}[/tex].
