Answer: $12.45.

Without a calculator, we can first round a dinner bill of $83.44 to the closest whole figure and estimate a 15% tip. In this instance, $83.44 can be rounded up to $83.

Then, we can calculate 15% of $83 by using a quick technique. In order to do this, we must first calculate 10% of $83, or $8.30. After that, we can calculate 5% of $83 by subtracting 50% of 10%, or $4.15.

Finally, we can add 10% and 5% together to get an estimate of 15% of $83:

$8.30 (10%) + $4.15 (5%) = $12.45

So, a 15% tip on a dinner bill of $83.44 would be approximately $12.45.

Answer: B. h=192÷ (6⋅4)

Step-by-step explanation:

B. h=192÷ (6⋅4)

This equation can be used to find the height of the prism because the volume of a rectangular prism can be represented by the equation V = l*w*h, where l and w are the length and width, respectively, and h is the height. In this case, given that V=192, the equation h=192÷ (l*w) can be used to find the height, where l=6 and w=4.

For the function f(x)=(x-2)^(2)-4, the transformation(s) done to the parent function are a horizontal shift to the right by 2 units and a vertical shift downward by 4 units.

The parent function of the function f(x)=(x-2)^(2)-4 is the quadratic function f(x)=x^(2).

The transformation(s) done to the parent function are a horizontal shift to the right by 2 units and a vertical shift downward by 4 units.

This can be seen by comparing the given function to the parent function. The (x-2) in the given function indicates the horizontal shift to the right, and the -4 at the end of the function indicates the vertical shift downward.

Therefore, the transformation(s) done to the parent function are a horizontal shift to the right by 2 units and a vertical shift downward by 4 units.

Answer:

1) To calculate how much it would cost Abi to buy 24 sodas at the vending machines at work, we can multiply the cost of one can ($0.75) by 24 (24 sodas):

Cost at vending machine = $0.75 x 24 = $18

2) To calculate how much Abi can save each day by buying the 24 pack of soda and taking one with her to work, we can subtract the cost of one can at the vending machine ($0.75) from the cost of the 24 pack at Foodtown ($3.25):

Savings each day = $3.25 - $0.75 = $2.50

The area of a trapezoidal region is 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height.

The area of a trapezoidal region is given by the formula A = 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height. This formula can be derived by dividing the trapezoid into two right triangles and a rectangle, and finding the area of each of these shapes.

First, let's consider the two right triangles. The height of each of these triangles is h, and the lengths of their bases are (a-b)/2 and (b-a)/2, respectively. The area of each of these triangles is therefore 1/2h(a-b)/2 = 1/4h(a-b).

Next, let's consider the rectangle. The length of this rectangle is b, and the height is h. The area of this rectangle is therefore bh.

The area of the trapezoidal region is the sum of the areas of the two right triangles and the rectangle. This gives us:

A = 1/4h(a-b) + 1/4h(b-a) + bh

Simplifying this equation gives us:

A = 1/2h(a+b)

Therefore, the area of a trapezoidal region is 1/2h(a+b), where a and b are the lengths of the two parallel sides, and h is the height.

The number of people we would expect to be found within an area of 1400 m by 1.3 km is approximately 25.

The mass of the cube for the object that has the side lengths of 56 cm is 0.043904 g.

1. To find the number of people in an area of 1400 m by 1.3 km, we need to first convert the measurements to the same unit. Since the population density is given in people/km2, we will convert the measurements to kilometers.
1400 m = 1.4 km
Now we can multiply the two measurements to find the area:
1.4 km x 1.3 km = 1.82 km2
Next, we can use the population density to find the number of people in this area:
14 people/km2 x 1.82 km2 = 25.48 people
Therefore, we would expect to find approximately 25 people in an area of 1400 m by 1.3 km.

2. To find the mass of the cube, we first need to find the volume. Since the side lengths are given in centimeters, we will convert them to meters:
56 cm = 0.56 m
Now we can find the volume of the cube by multiplying the side lengths:
0.56 m x 0.56 m x 0.56 m = 0.175616 m3
Next, we can use the density to find the mass of the cube:
0.25 g/m3 x 0.175616 m3 = 0.043904 g
Therefore, the mass of the cube is 0.043904 g.

The given statement in the problem (f/g)(-2) = -6/5 is true.

A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.

We are given that;

f(x) = 3x²

g(x) x - 8 ; (f/g)(-2) = -6/5

Now,

To evaluate (f/g)(-2), we need to divide f(-2) by g(-2).

Answer: It is not possible to use only translations and dilations to map one circle to another unless the two circles are identical in size and shape.

A translation is a transformation that moves an object without changing its size, shape, or orientation. It involves moving every point on the object the same distance in the same direction. Since a circle is defined by all the points that are equidistant from its center, a translation will simply move the entire circle in the same direction, but will not change its size or shape.

A dilation is a transformation that changes the size of an object, but not its shape or orientation. It involves multiplying the distance of every point on the object from a fixed center point by a scale factor. While a dilation can change the size of a circle, it will also change the distance between points on the circle, and thus change its shape.

Therefore, if the two circles are not identical in size and shape, it would be necessary to use other transformations, such as rotations or reflections, to map one circle to the other.

The population after 4 years will be 12,155.06. It will take approximately 22.52 years for the population to triple.

The population of a town grows proportionally to its current population. This means that the larger the population, the more it will grow. To determine the population after 4 years, we can use the formula:

P = P0 * (1 + r)^t

Where P is the final population, P0 is the initial population, r is the growth rate, and t is the time in years. Plugging in the values given in the question, we get:

P = 10,000 * (1 + 0.05)^4

P = 10,000 * 1.21550625

P = 12,155.06

Therefore, the population after 4 years will be 12,155.06.

To determine how long it will take the population to triple, we can use the same formula, but set P to 3 * P0 and solve for t:

3 * 10,000 = 10,000 * (1 + 0.05)^t

3 = (1 + 0.05)^t

ln(3) = t * ln(1.05)

g(f(x)) = 3(f(x))^(2)-7(f(x))+4

Now we can substitute the expression for f(x) into the equation:

g(f(x)) = 3(x+5)^(2)-7(x+5)+4

Next, we need to simplify the expression by expanding the squared term and distributing the -7:
