The perimeter of a rectangle is given by the formula P = 2(l+w), where l is the length and w is the width of the rectangle. The correct answer is that the perimeter is increased by a factor of 10.

In this case, the width is 3 cm and the length is 10 cm, so the initial perimeter is:

P = 2(10+3) = 26 cm

Now, if we multiply the dimensions by 10, the new length would be 10 x 10 = 100 cm and the new width would be 3 x 10 = 30 cm. The new perimeter would then be:

P' = 2(100+30) = 260 cm

Comparing the initial perimeter to the new perimeter, we can see that the new perimeter is 260/26 = 10 times larger than the initial perimeter. Therefore, the correct answer is that the perimeter is increased by a factor of 10

It's important to note that the word "factor" is often used to describe the degree to which something changes. In this case, a factor of 10 means that the new perimeter is 10 times larger than the initial perimeter. If we were to use the word "increase" instead, we would say that the perimeter is increased by 250% (or 2.5 times).

Answer: Let's call the height of the steeple "h". We can use the tangent function to set up an equation involving the angles of elevation:

tan(40°) = h / x

tan(49° 40') = (h + y) / x

where "x" is the distance from the point to the base of the steeple, and "y" is the height of the point above the ground.

We are given that the distance from the point to the church is 48 feet, so we can use the Pythagorean theorem to find the value of "y":

y^2 = x^2 - 48^2

We can substitute this expression for "y" into the second equation above:

tan(49° 40') = (h + √(x^2 - 48^2)) / x

We can now solve this equation for "h":

h = x tan(49° 40') - x √(1 + tan^2(49° 40')) + 48 tan(40°)

Plugging in the values for the angles and solving for "h", we get:

h ≈ 83.9 feet

Therefore, the height of the steeple is approximately 83.9 feet.

b. Jaqi still οwes 41.67% οf her debt.

c. Jaqi's debt nοw is $25.

d. Jaqi wοuld have paid οff 40% οf her new debt.

Percentage can be calculated by dividing the value by the tοtal value, and then multiplying the result by 100.

a. Tο find the percentage οf the debt that Jaqi has paid, we need tο divide the amοunt paid by the tοtal amοunt οwed and multiply by 100:

Percentage paid = (Amοunt paid / Tοtal amοunt οwed) x 100%

Percentage paid = (35 / 60) x 100%

Percentage paid = 58.33%

Sο Jaqi has paid 58.33% οf her debt.

b. Tο find the percentage still οwed, we can subtract the amοunt paid frοm the tοtal amοunt οwed, and then calculate the percentage:

Percentage still οwed = (Amοunt still οwed / Tοtal amοunt οwed) x 100%

Percentage still οwed = ((60 - 35) / 60) x 100%

Percentage still οwed = 41.67%

Sο Jaqi still οwes 41.67% οf her debt.

c. Tο find Jaqi's debt nοw, we simply subtract the amοunt paid frοm the οriginal debt:

Debt nοw = Tοtal amοunt οwed - Amοunt paid

Debt nοw = 60 - 35

Debt nοw = $25

Sο Jaqi's debt nοw is $25.

d. If Jaqi pays anοther $10 tοward her new debt οf $25, we can find the percentage paid as fοllοws:

Percentage paid = (Amοunt paid / Tοtal amοunt οwed) x 100%

Since the pole is in the shape of a cylinder, its volume can be calculated using the formula V = πr²h, where r is the radius and h is the height (or length in this case). We are not given the radius, so we cannot calculate the exact volume. However, we can use an approximation assuming a reasonable radius.

Let's assume a radius of 1 foot. Then, the volume would be V ≈ π(1)²(15) = 15π ≈ 47.1 cubic feet.

The closest answer choice to this approximation is D) 141 ft². However, note that volume is measured in cubic units (feet cubed or ft³), not square units (feet squared or ft²). Therefore, none of the answer choices are in the correct units for the volume of a cylinder.

If both computers work together it will take them 12 minutes to do the same job.

We will be using the given formula :

Let the amount of work to be done be 1 (all the email sent).

The efficiency of the slower computer is 1/30.

The efficiency of the faster computer is 1/20.

When both computers work together, the efficiency of the slower computer and the efficiency of the faster computer are added, so their efficiency is 1/30 + 1/20 = 1/12.

Substituting the values in the formula, we have :

To arrange these measurements in order from biggest to smallest,

Convert all the measurements in the same units.

Convert all of them to meters,

1 meter = 100 centimeter

To convert centimeter to meter divide it by 100 we get,

105 cm

= 105 / 100 m

Answer:

7

Step-by-step explanation:

Answer:

M = P [ i(1 + i)^n ] / [ (1 + i)^n - 1]

where M is the monthly payment, P is the principal (the cost of the house minus the down payment), i is the monthly interest rate (6.00% divided by 12), and n is the total number of payments (30 years times 12 months per year).

Plugging in the values, we get:

P = $450,000 - 0 (assuming no down payment)

i = 0.06 / 12 = 0.005

n = 30 x 12 = 360

M = $450,000 [ 0.005(1 + 0.005)^360 ] / [ (1 + 0.005)^360 - 1] = $2,695.55

So the monthly mortgage payment is $2,695.55.

To find the monthly payment with taxes and insurance, we need to add the yearly taxes and insurance and divide by 12 to get the monthly amounts. So:

Monthly Taxes = $2,000 / 12 = $166.67

Monthly Insurance = $1,500 / 12 = $125.00

Total Monthly Payment with Taxes and Insurance = $2,695.55 + $166.67 + $125.00 = $2,987.22

Therefore, the monthly payments with taxes and insurance for the $450,000 house loan are $2,987.22.

In response to the stated question, we can state that here  Hence, the linear equation (6 2 • 35) 2 equals 1/4096

A linear equation is one that satisfies the algebraic formula y=mx+b. m is the y-intercept, while B is the slope. The foregoing sentence is sometimes referred to as a "linear equation with two variables" because y and x are variables. Bivariate linear equations are two-variable linear equations. Examples of linear equations include 2x - 3 = 0, 2y = 8, m + 1 = 0, x/2 = 3, x + y = 2, and 3x - y + z = 3. An equation is said to be linear if its formula is y=mx+b, where m denotes the slope and b the y-intercept. It is referred to as being linear when an equation has the form y=mx+b, where m stands for the slope and b for the y-intercept.

We must do the following operations in the correct order to simplify the formula (62 • 35)2:

To start, we must multiply 2 by 35, which results in the number 70.

The result is -64 when we remove 70 from 6.

The final step is to raise the unfavorable integer -64 to the power of -2.

Hence, we can write:

[tex](6-2 * 35)-2 = (-64)^{-2}[/tex]

To make this statement easier to understand, keep in mind that taking the reciprocal of a number raised to a positive power is the same as raising it to a negative power. With those words:

[tex]a^-n = 1/a^n\\(-64)^-2 = 1/(-64)^2\\1/(-64)^2 = 1/4096[/tex]

The thickness of a hollow cylinder which is also the thickness of the metal is 1cm

To calculate the thickness of a hollow cylinder, subtract the inner and outer cylinder radii, r and R:

the thickness of the solid is:t = R - r

And if we are working with the diameter, we subtract the diameters and divide by 2VH = π × h(D² - d²)/4

where

Vh = Volume of hollow cylinder = 748cm  

h = height of cylinder = 14cm

D = external diameter = 9 x 2 = 18cm

d = internal diameter = ??

The above statements can then be represented as:

4 x 748 = 22/7 x 14 (18² - d²)

Evaluate the products, quotients and exponents

68 = 324 - d²

So, we have

d² = 256

Take the square roots

d = 16 cm

From here we can get the thickness by subtracting the external and internal diameter and dividing by 2

thickness = (18 - 16)/2

thickness = 2/2
