The scale of a drawing is 1/4 in = 12ft. Find the actual measurement of 8in

Answer:

  A.  63°

Step-by-step explanation:

You want to know the base angle in the isosceles triangle in the given figure.

Angle ABC is the sum of its parts:

  ∠ABC = ∠ABD +∠DBC

The figure shows ∆DBC is equilateral, so ∠DBC = 60°. This lets us solve for the measure of angle ABD:

  114° = ∠ABD +60°

  54° = ∠ABD

∆ABD is isosceles, so the two base angles are congruent. The sum of angles in the triangle is 180°, so we have ...

  ∠ABD +∠BAD +∠BDA = 180°

  54° +2(∠BAD) = 180° . . . . . . . ∠BAD =∠BDA

  ∠BAD = 90° -27° . . . . . . divide by 2, subtract 27°

  ∠BAD = 63°

The bricks having same cost per brick are 1500 bricks for $1,110, 35 bricks for $25.90 and 230 bricks for $170.20. The solution has been obtained using the unitary method.

What is a unitary method?

The value of a single unit is calculated in the unitary approach before the value of the necessary number of units is determined. In order to obtain value of a single unit from a given multiple, the unitary technique is used, to put it simply.

We know that Cost per brick = number of bricks / price of bricks

Therefore, using this, we get

1500/$1110 = $1.35

1300 / $845 = $1.54

230 / $170.20 = $1.35

100 / $75 = $1.33

35 / $25.90 = $1.35

Hence, the bricks having same cost per brick are 1500 bricks for $1,110, 35 bricks for $25.90 and 230 bricks for $170.20.

Answer: 2

Step-by-step explanation: The value x in f(x) is a value on the x-axis that we input into the function. F(x) is a value on the y-axis. F(2) means we are inputting the value of 2 on the x-axis and looking for the corresponding point on the y-axis. If we look at the graph at x=2, we can see that the graph is above when y=2. This means that (2,2) is a point that satisfies f(x).

Answer:

The circumference of the wheel is 2 * pi * r = 2 * 3.14 * 225 mm = 1413.8 mm.

The number of arcs between each spoke is 25 - 1 = 24.

So, the arc length between each spoke is the circumference of the wheel divided by the number of arcs, which is 1413.8 mm / 24 = 58.91 mm.

Decay constant: the ratio of the number of radioactive atoms in a population to the rate at which they are vanishing due to radioactive decay. The rate of change is determined by the equation dN/dt = N, where is the decay constant, assuming N is the size of a population of radioactive atoms at a particular time t and dN is the amount by which the population declines in time dt.

When this equation is integrated, N = N0et is obtained, where N0 is the starting population size of radioactive atoms at time t = 0. This demonstrates that the rate of population decay is dependent on the decay constant and is exponential.

Addition, subtraction, multiplication, or division are all examples of math operations. A number, a variable, or a combination of numbers, variables, and operation symbols constitutes an expression.

The number of each type of tickets which August sold is equal to: B. 20 students and 15 adults.

In order to write a system of linear equations to describe this situation, we would assign variables to the number of adult tickets sold and number of student tickets sold, and then translate the word problem into an algebraic equation as follows:

Since Adults pay $7 a ticket while students pay $5 a ticket for a total cost of $205, an algebraic equation to model is given by;

7a + 5s = 205

For the sales of 35 tickets, we have:

a + s = 35      

Solving for a, we have the following:

7a + 5(35 - a) = 205

7a + 175 - 5a = 205

2a = 205 - 175

2a = 30

a = 30/2

a = 15 adult tickets.

For the number of student tickets, we have:

s = 35 - a

s = 35 - 15

s = 20 student tickets.

A protractor is used to measure angles in degrees (°). With the aid of a protractor, one may measure and calculate angles in terms of degrees.

Through the use of a protractor, angles are measured in degrees (°). In order to calculate or draw angles in terms of degrees, a protractor is a measuring tool that is utilised. Using a protractor, for instance, we can observe that the black arrow in the image below crosses the 90° line at 100°. Thus, the angle has a 100° measurement.

Generally speaking, supplementary angles are those where the total of two angles is greater than 180 degrees. A supplement to another angle is stated to exist for each of the angles. By deducting an angle's complement from 180 degrees, we can calculate its value.

A 113 degree angle's complement is a 67 degree angle.

Depth is the result of form having the illusion of the third dimension.

Even while the human brain perceives many flat pictures, such as those in movies and photographs, as being two dimensional, nothing actually exists without all three dimensions (2D). This is due to the fact that everything physically existing is made of atoms, which are imperceptible to the human sight yet include all three spatial dimensions. Human eyes have the capacity to perceive "depth" or three dimensions. The three spatial dimensions of the world may be perceived by someone who possesses depth perception. Each human eye's visual brain first interprets the three spatial dimensions as 2D pictures. Contrarily, stereoscopic vision, which is unique to humans, alters the image seen by the two eyes.

The exact length of the given curve is 62/3

We can calculate the above answer by following the steps given below,

We have been given the following values,

The curve is of the length, x = f(y) from y =a to y = b is given by:

x = 1/3 √y (y - 3)

x = 1/3 (- 3)

dx/dy = 1/3 [(3/2)- (3/2)]

= 1/3 [(3/2) - (3/2)]

= 1/2 [ - 1/]

= (y-1)/2√y = f'(y)

Now we will calculate the length of the curve

= [tex]\int\limits^a_b{\sqrt{1+ (\frac{y-1}{2\sqrt{y} } )^2} } \, dy[/tex]  (here a= 4, b=16)

Answer:

To calculate the amount Sophia needs to invest to reach a certain value in a specific time, given an interest rate compounded monthly, we can use the formula:

A = P(1 + r/n)^(nt)

Where:

A = the future value of the investment

P = the initial principal or investment amount

r = the annual interest rate (expressed as a decimal)

n = the number of times the interest is compounded per year

t = the number of years the investment is held

Since the interest is compounded monthly, we need to divide the annual rate by 12 to find the monthly rate. So:

r/12 = 0.034/12 = 0.002833

Now we can plug in the values into the formula:

A = P(1 + 0.002833)^(12*14)

A = P(1.002833)^(168)

We know that A = $1,450 and we want to find P (the initial principal or investment amount).

So we can rearrange the equation to find P:

P = A/(1.002833)^(168)

Solving for P, we get:

P ≈ $973.99

So Sophia would need to invest around $973.99 to reach $1,450 in 14 years with an annual interest rate of 3.4% compounded monthly.

Step 1: Simplify both sides of the equation.

7 − 8(x − 3) = x − 14

7 + (−8)(x) + (−8)(−3) = x + − 14 (Distribute)

7+ (−8x) + 24 = x + (−14)

(−8x) + (7+24) = x − 14 (Combine Like Terms)

−8x + 31 = x − 14

−8x + 31 = x − 14

Step 2: Subtract x from both sides.

−8x + 31 − x = x − 14 − x

−9x + 31 = −14

Step 3: Subtract 31 from both sides.

−9x + 31 − 31 = −14 − 31

−9x = −45

Step 4: Divide both sides by -9.
