Answer:

[tex]SA=1.5\ cm^2[/tex]

Step-by-step explanation:

we know that

The surface area of a cube is equal to

[tex]SA=6s^2[/tex]

where

s is the length side of a cube

we have

[tex]s=\frac{1}{2}\ cm[/tex]

substitute

[tex]SA=6(\frac{1}{2})^2[/tex]

[tex]SA=(\frac{6}{4})=1.5\ cm^2[/tex]

Step-by-step explanation:

thirty percent of $28 is $8.4, so you would subtract the two leaving you with $19.6

2.5 sales tax of $19.6 is $0.49

Adding those two, the total comes to 20.09 which is just over budget

The amount of the book is more than $20. Then she does not have enough money.

The amount of any product is given as though it was a proportion of a hundred. The ratio can be expressed as a quarter of 100. The phrase % translates for one hundred percent. It is symbolized by the character '%'.

The percentage is given as,

Percentage (P) = [Final value - Initial value] / Initial value x 100

Let 'x' be the markdown price. Then the equation is given as,

30% = [(28 - x) / 28] × 100

0.30 = [(28 - x) / 28]

8.4 = 28 - x

x = $19.6

Then the amount of book after tax is given as,

⇒ $19.6 x 1.025

⇒ $20.09

The amount of the book is more than $20. Then she does not have enough money.

Answer:

The probe's final position is -143m

Step-by-step explanation:

Note that the words 'lowered' and 'below' mean subtract; while the word 'raised' means add. Thus, interpreting the statement to mathematical expression is done below.

[tex] - 90m + 50m - 138m + 35m[/tex]

[tex] = - 143m[/tex]

Therefore, the probe's final position is -143m. Hence, the sensor is 143m below the sea level.

Final answer:

To calculate the volume of a cylindrical sugar container with a radius of 3 inches and a height of 10.5 inches, use the formula V = πr²h, which yields approximately 296.78 cubic inches.

Explanation:

The question asks for the volume of the container that has the shape of a cylinder. The given dimensions are a radius of 3 inches and a height of 10.5 inches. To find the volume of a cylinder, we use the formula:

V = πr²h

Where V is the volume, π (pi) is a constant approximately equal to 3.14159, r is the radius, and h is the height of the cylinder.

We calculate the volume as follows:

V = π × (3 inches)² × 10.5 inches

V = π × 9 in² × 10.5 in

V = π × 94.5 in³

V ≈ 296.78 in³

Thus, the volume of the cylinder is approximately 296.78 cubic inches

Step-by-step explanation:

The area of the metal frame surrounding a circular mirror can be calculated by figuring the expression 225x² - 9πx², which represents the area of the square minus the area of the circle.

The subject of this question is based in mathematics, specifically the area of geometry. The area of the metal frame surrounding the mirror can be found by calculating the difference between the area of the square frame and the area of the circular mirror.

The area of the square frame is given by the formula A = s² where 's' is the length of a side of the square. In this case, each side of the square is 15x so the area of the square frame would be (15x)² = 225x².

The area of the circular mirror is given by the formula A = πr² where 'r' is the radius of the circle. For this mirror, the radius is 3x, so the area of the mirror would be π*(3x)² = 9πx².

So, the area of the metal frame is the difference between the area of the square and the area of the circle. Thus, the area of the frame = 225x² - 9πx².

https://brainly.com/question/34380164

#SPJ12

Final answer:

To find the area of the metal frame, calculate the area of the square then subtract the area of the circle. The area of the frame is the difference between the square's area, (15x)², and the circle's area, π(3x)².

Explanation:

The question asks for the area of the metal frame surrounding a circular mirror with the mirror's radius being 3x and the frame's side length being 15x.

To find the area of the frame, first calculate the area of the square and then subtract the area of the circle (mirror). The area of the square is given by the formula A = side², so:

Next, calculate the area of the circle using the formula A = πr²:

Finally, subtract the mirror's area from the frame's area to find the area of the metal frame alone:

Answer:

B)

Step-by-step explanation:

All three trigonometric functions  are positive in Quadrant I

Sine only is positive in Quadrant II

Tangent only is positive in Quadrant III

Cosine only is positive in Quadrant IV

Now

tan 116°           tan 116° means that the angle 116° lies in the second quadrant.

sin is positive while cos and tan are negative in the second quadrant

tan 116° = -tan(180°-116)

= -tan(64°)

Scalene means it has no equal side.

Area of the circle is 78.5 sq. units.

Step-by-step explanation:

Circumference of the circle = 31.4 units

2 π r = 31.4 units

2 × 3.14 ×r = 31. 4 units

r = 31.4 / (2×3.14)

= 5 units.

Area of the  circle = π r² = 3.14 × 5 × 5 = 78.5 sq. units.

Answer:

42 and 58

Step-by-step explanation:

Let the two numbers be represented by A And B

A + B = 100

A = B + 16

Substitute B + 16 in place of A in equation 1

We have,

B + 16 + B = 100

It can also be written as

B + B + 16 = 100

2B + 16 = 100

Subtract 16 from both sides

2B + 16 - 16 = 100 - 16

2B = 84

Divide both sides by 2

2B/2 = 84/2

B = 42

Now substitute 42 for B in any of the equations to get A.

Using equation 1

A + B = 100

A + 42 = 100

Subtract 42 from both sides

A + 42 - 42 = 100 - 42

A = 58

Therefore the two numbers are 42 and 58

Final answer:

The proportional relationship between the number of rides and time is represented by the equation t = 3n where t is the total time in minutes and n is the number of rides.

Explanation:

Since it takes Esther 12 minutes to ride a roller coaster four times, we can find the time taken for one ride by dividing the total time by the number of rides.

Time for one ride = Total Time / Number of Rides = 12 minutes / 4 rides = 3 minutes per ride.

The proportional relationship between the number of rides (n) and the total amount of time (t) can be represented by the equation t = 3n. This indicates that for every ride, 3 minutes are added to the total time.

Answer:

6πr/11.

Step-by-step explanation:

The length of the arc = rC where C is the central angle of the sector in radians and r = the radius.

C = (3/11) * 2π

= 6π/11 radians.

So the measure of the arc = 6πr/11.

2. The total number of calculators is 6 + 9 + 2 = 17.

When she hands out the first calculator, the probability that it is blue is 2/17.

When she hands out the second calculator, there is one less calculator total, so the probability that it is yellow is 9/16.

The probability of both is therefore:

P = 2/17 × 9/16

P = 9/136

3. There are 13 clubs in a standard deck of 52 cards.

The probability that the first card is clubs is 13/52 = 1/4.

Since you replace the card, there are still 52 cards in the deck.  So the probability that the second card is clubs is 13/52 = 1/4.

The probability that both cards are clubs is:

P = 1/4 × 1/4

P = 1/16

4. The total number of pieces of gum is 6 + 9 + 5 = 20.

When you pick the first piece, the probability that it is grape is 6/20.

When you pick the second piece, there's one less piece of gum, and one less grape flavor, so the probability is 5/19.

The probability that both pieces are grape is:

P = 6/20 × 5/19

P = 3/38

5. The total number of drinks is 6 + 3 + 4 = 13.

Since the coach replaces the first drink, the second selection will be independent of the first.  So the probability is still P = 6/13.

6. A die has six sides.  They are numbered 1 through 6.  Three of the numbers are even.  Each roll is independent, so the probability of a previous roll does not affect the probability of future rolls.

The probability that you get 3 even numbers, followed by a one, is:

P = (3/6) (3/6) (3/6) (1/6)

P = 1/48
