Answer: 1

Step-by-step explanation:

[tex]\frac{12}{3*4} \\[/tex]

[tex]\frac{12}{12}=1[/tex]

Final answer:

The phrase 'the quotient of 12 and the product of 3 and 4' translates to the algebraic expression 12 ÷ (3 × 4), which simplifies to 1.

Explanation:

To translate the given phrase into an algebraic expression, we need to understand the terms used. The phrase is 'the quotient of 12 and the product of 3 and 4'. A 'quotient' is the result of division, and a 'product' is the result of multiplication. First, let's find the product of 3 and 4, which is 3 × 4. This equals 12. Now, we take the quotient of 12 by that product, which means we divide 12 by 12. So, the algebraic expression is 12 ÷ (3 × 4).

When we simplify this expression, since 3 × 4 equals 12, and 12 divided by 12 is 1, the expression simplifies to 1. Therefore, the simplified algebraic expression for the phrase 'the quotient of 12 and the product of 3 and 4' is 1.

Step-by-step explanation:

She will gain $ 6885.4896 after 10 years if she chooses 3.85% account.

Step-by-step explanation:

Given,

Principle (P) = $ 15000

Time (T) = 10 years

Rate of interest (R) = 3.85%

To find the compound interest.

Formula

CI = [tex]P(1+\frac{R}{100} )^{T}-P[/tex]-P

Putting the values we get,

CI =  [tex]15000(1+\frac{3.85}{100} )^{10}-15000[/tex]

= 21885.4896-15000

= 6885.4896

Hence,

She will gain $ 6885.4896.

Answer:

2 hours

Step-by-step explanation:

30 miles/x hours = 15 miles/1 hour

30 = 15x

x = 2 hours

To find the time it took to get to the store, divide the distance traveled (30 miles) by the average speed (15 mph), which results in 2 hours. Thus, the trip took 2 hours.

To calculate the time it took to get to the store, we can use the formula time = distance ÷ speed. In this case, the vehicle traveled 30 miles at an average speed of 15 miles per hour. Therefore, the time can be calculated as follows:

Time = 30 miles ÷ 15 miles per hour = 2 hours.

So, it took 2 hours to get to the store.

HAVE A NICE DAY!

THANKS FOR GIVING ME THE OPPORTUNITY TO ANSWER YOUR QUESTION.

The product of 4.5 ⋅ 105 and 1.6 ⋅ 102 is 7.2 ⋅ 107. This is achieved by first multiplying the coefficients (4.5 and 1.6), and then adding the powers of 10 (105 + 102).

First, to multiply these numbers in scientific notation, we begin by multiplying the coefficients and then add up the powers of 10.

So, 4.5 ⋅ 1.6 = 7.2 and then 105 + 102 = 107. Therefore, the product of 4.5 ⋅ 105 and 1.6 ⋅ 102 is 7.2 ⋅ 107. This means it is the second option listed in your potential multiple choice answers above.

Answer:

Option C

Step-by-step explanation:

If angle w is 112, angle x has to also be 112

so 112+112=224

all of the angles summed up has to 360, so you subtract 360-224

which equals 136

then divide by 2 and you get 68

Hopefully this makes sense

Answer:

The answer is C: 68

Step-by-step explanation:

The trapezoid has a total amount of 360 degrees.

W = 112 degrees.

W and X are congruent so X also equals 112

SO if you add them together, it is equal to 224.

Subtract from 360 and 136 is left.

Divide by 2 because there is Z and Y(2 angles left) which are also congruent.

This gives the angles measurements of 68 for both Z and Y

The sum of the areas of the two shaded sectors is 36 π units²

A sector is said to be a part of a circle made of the arc of the circle along with its two radii.

Given that a circle, with central angle 80° and the radius is 9 units

So, area of a sector = θ/360° x π x radius², where θ = central angle

Since, both the sectors are vertically opposite to each other so will same areas,

Therefore, the area of the two shaded sectors,

= 2θ/360° x π x radius²

= 2·80/360 × π × 9²

= 4/9 × π × 81

= 36π

Hence, the sum of the areas of the two shaded sectors is 36 π units²

Answer:

127.4

Step-by-step explanation:

a^2+b^2-2(ab)CosC

The side f will be 127.41 cm long.

The law of cosine states that the square of any one side of a triangle is equal to the difference between the sum of squares of the other two sides and double the product of other sides and cosine angle included between them.

Given is triangle DEF, we need to find the length of the side f, if d = 92 cm, e = 42 cm and ∠F = 141°.

So, using the cosine law,

[tex]c^2=a^2+b^2-2ab\cdot \cos \left(\gamma \right)[/tex]

Therefore,

[tex]f=\sqrt{d^2+e^2-2de\cos 141_{\degrees}[/tex]

[tex]f=\sqrt{42^2+92^2-2\cdot \:42\cdot \:92\cos \left(141^{\circ \:}\right)}[/tex]

f = 127.41

Hence the side f will be 127.41 cm long.

Answer:

Step-by-step explanation:

Final answer:

The correct point that lies on the circle defined by the equation (x − 5)² + (y + 3)² = 25 is point C (2, 1), as substituting these values into the equation results in 25, which matches the right side of the equation. Thus, option C is correct.

Explanation:

To find which point is on the circle given by the equation (x − 5)² + (y + 3)² = 25, you can plug the x and y values from each option into the equation and see if it holds.

For point A (5, − 3), the equation becomes (5 − 5)² + (− 3 + 3)², which simplifies to 0 + 0 = 0. This is not equal to 25, so point A is not on the circle.

For point B (8, − 6), the equation becomes (8 − 5)² + (− 6 + 3)², which simplifies to 9 + 9 = 18. This is not equal to 25, so point B is not on the circle.

For point C (2, 1), the equation becomes (2 − 5)² + (1 + 3)², which simplifies to 9 + 16 = 25. This is equal to 25, so point C is on the circle.

For point D (4, − 8), the equation becomes (4 − 5)² + (− 8 + 3)², which simplifies to 1 + 25 = 26. This is not equal to 25, so point D is not on the circle.

The correct answer is point C (2, 1), as it satisfies the equation of the circle.

Answer:

it should equal 68 degrees.

Step-by-step explanation:

if you are looking for the value of m<1, you would first need to find the value of the missing angle on the left triangle. the angles in triangles are equal to 180 degrees, so the equation would be 180 = 50 + 80 + x, and x = 50.

Then move to the middle triangle. The angle you solved for has an angle "connected" to it, its vertical pair, which also equals 50. Then you solve for the last angle, the angle on the right. 180 = 50 + 62 + x, and x = 68.

m<1 is equal to its vertical angle, which is the angle you just solved for. its value should be 68 degrees.

if that wasn't what you were looking for, sorry. hope this helped :)

The amount of the IRS fee you will have to pay is A. $750.00.

Percentage is defined as the parts of a number per fraction of 100. We have to divide a number with it's whole and then multiply with 100 to calculate the percentage of any number.

Percentage is usually denoted by the symbol '%'.

Given that,

Amount you invested at the age of 40 = $20,000

You will receive payments at the age of 50.

Amount withdrawn at the age of 47 = $7500

IRS charges 10% if you withdraw before you are 59.5.

Since your age is 47, you have to pay 10% IRS fees.

IRS fees = 10% of 7500

              = 10/100 × 7500

              = $750

Hence the IRS fee you will have to pay is A. $750.00.

Experimentally, it could be anything between 0-300, although after so many trails in it, it would be extremely likely that it would be near 150.

Final answer:

To find the width (w) of the rectangle, set up an equation using the given information and the formula for the perimeter of a rectangle. Solve the equation to find the width.

Explanation:

To find the width (w) of the rectangle, we can set up an equation based on the given information and the formula for the perimeter of a rectangle. Let's start by assigning variables: let w be the width of the rectangle and let l be the length of the rectangle. According to the problem, the length of the rectangle is 4 feet less than 3 times its width. So we have the equation l = 3w - 4. The perimeter of a rectangle is given by the formula P = 2(l + w), where P is the perimeter. Since the perimeter is given as 54 feet, we have the equation 54 = 2(l + w). We can substitute the expression for l from the first equation into the second equation: 54 = 2((3w - 4) + w). Simplifying this equation will allow us to solve for the width (w) of the rectangle.
