Answer:

527.52 ft²

Step-by-step explanation:

The surface area of a cylinder is:

[tex]\displaystyle{2\pi r^2 + 2\pi r h}[/tex]

where r is radius and h is height.

From the attachment, we know that the radius (r) is 7 ft and the height is 5 ft. Therefore:

[tex]\displaystyle{\text{Surface Area} = 2 \cdot 3.14 \cdot (7)^2 + 2\cdot 3.14 \cdot 7 \cdot 5}\\\\\displaystyle{\text{Surface Area} = 6.28 \cdot 49 + 6.28 \cdot 35}\\\\\displaystyle{\text{Surface Area} = 307.72 + 219.80}\\\\\displaystyle{\text{Surface Area} = 527.52 \ \: \text{ft}^2}[/tex]

Therefore, the surface area of the cylinder is 527.52 ft²

Answer:

To find the account balance after 5 years, we need to calculate the compound interest earned during this period. The formula for compound interest is:

A = P × (1 + r/n)^(nt)

where:

A = the final amount of the investment

P = the principal investment amount ($1000)

r = the annual interest rate (7.2%)

n = the number of times that interest is compounded per year (1)

t = the number of years the investment is held (5)

So, plugging in the values into the formula, we get:

A = 1000 * (1 + 0.072/1)^(1 * 5)

A = 1000 * (1.072)^5

A = 1000 * 1.44444444

A = $1444.44

So, the account balance after 5 years would be $1444.44.

The length of the UW of the triangle is 18. The correct option is D.

Pythagorean theorem states that in the right angle triangle, the hypotenuse square is equal to the square of the sum of the other two sides. According to this statement, the areas of the squares on the other two sides add up to the size of the square whose side is the hypotenuse.

The length UW will b calculated as:-

First, in ΔTWU apply the Pythagorean theorem,

TU² = UW² + 12²

TU² = UW² + 144

In ΔTWV apply the Pythagorean theorem,

VT² = 12² + 8²

VT² = 208

Apply Pythagorean theorem in ΔVTU,

( 8 + UW)² = VT² + TU²

Substitute the value of TU² in the above equation,

( 8 + UW)² = 208 + UW² + 144

UW² + 16UW + 64 = UW² + 208 + 144

16UW = 288

UW = 288 / 16 = 18

Therefore, the length of UW is 18.

Answer: Let's call the number of hamburgers sold "x". Then the number of cheeseburgers sold would be x + 53. The total number of hamburgers and cheeseburgers sold is 553, so we can set up the equation:

x + (x + 53) = 553

Expanding the left side:

2x + 53 = 553

Subtracting 53 from both sides:

2x = 500

Finally, dividing both sides by 2:

x = 250

So on Wednesday, 250 hamburgers were sold.

Step-by-step explanation:

Note that the angle labeled ∠PQR is given as 70°

First, note that the Lengths of tangents drawn from external points to a circle are equal in length. This means that:

Length of PT = Lenght of TR

This makes Δ TPR and Isosceles Triangle.

This also makes ∠P = ∠R..............................1

Thus:

∠P + ∠R + ∠T = 180°

Given expression 1 above,

we can say:

x + x + 38° = 180°

Thatis 2x = 180 - 40

2x = 140°

x = 140/2

x = 70°

Note that Line TP is parallel to Line QR and Line PQ is a transversal line. Thus, ∠P and ∠Q are co-interior angles. This means that:

∠P + ∠Q = 180°

Recall that:

70 + 40 + ∠Q = 180°
∠Q = 180 -70 -40

∠Q = 70°

Thus: ∠ PQR = 70°

Answer: The temperature of an oven can be modeled by a linear equation. In this case, the initial temperature of the oven is 75° and it will increase at a rate of 25° per minute after being turned on.

The equation to model the temperature of the oven t minutes after being turned on is:

Temp = 75 + 25t

Where Temp is the temperature of the oven in degrees and t is the number of minutes after being turned on.

For example, if we want to find the temperature of the oven 17 minutes after being turned on, we can substitute t = 17 into the equation:

Temp = 75 + 25 * 17 = 75 + 425 = 500°

So, the temperature of the oven 17 minutes after being turned on is 500°.

In general, the temperature of the oven t minutes after being turned on can be found by substituting the value of t into the equation:

Temp = 75 + 25t.

Step-by-step explanation:

The temperature of an oven can be modeled by a linear equation. In this case, the initial temperature of the oven will be;  75° and it will increase at a rate of 25° per minute after being turned on.

An equation is an expression that shows the relationship between two or more numbers and variables.

The measure of angle D, m∠D, found using the specified lengths of the three sides of the triangle and the law of cosines is; m∠D = 75.7°

The law of cosines specifies the relationship between the measures of an angle, and the lengths of the three sides of a triangle. Specifically, the law of cosines states that the square of the length of a (reference) side of a triangle, is equivalent to the sum of the squares of the lengths of the other two sides, less the product of 2, the lengths of the other two sides and the cosine of the angle opposite to the reference side.

Mathematically, the law of cosines can be presented as follows;

Where;

a, b, and c are the lengths of the three sides of the triangle

Angle A, ∠A, is the opposite angle to side a.

Therefore, according to the law of cosines, we get;

38² = 36² + 24² - 2 × 36 × 24 × cos(∠D)

2 × 36 × 24 × cos(∠D) = 36² + 24² - 38² = 428

2 × 36 × 24 × cos(∠D) = 428

cos(∠D) = 428/(2 × 36 × 24) = 428/1728 = 107/432

cos(∠D) = 107/432

Answer:

Step-by-step explanation:

The monthly compound interest formula.

Future Value = monthly deposit x (1 + r) - 1/r

r = .07/12 = .00583

n = total number of time for compound = 35 years x 12 months/1 year = 420 months

PMT = monthly deposit = $200

Future Value = $200 x (1 + .00583)⁴²⁰ - 1/.00583

Future Value = $394,001.64 in 35 years

Total money you put into the account.

$200 x 420 months = $84,000
