Joe made a mistake in his calculations by multiplying 28 quarts by 4.

To know the mistake that Joe made and the possible correction, we shall convert 28 quart to gallon.

Recall that 4 quart = 1 gallon

Therefore, 28 quart will be:

= 28 quart × 1 gallon / 4 quart

28 quart = 7 gallon

Therefore, 28 quarts is equivalent to 7 gallons.

Hence, Joe made a mistake in his calculations by multiplying 28 quarts by 4 instead of dividing 28 quart by 4.

Brooke's yard is a square with a side length of 22 meters.

Perimeter is the total distance around the outside edge of a two-dimensional shape. Perimeter is a measure of the length of the boundary of a shape and is typically expressed in units of length, such as feet or meters. Calculating the perimeter of a shape can help you measure the size of a yard, garden, or other outdoor area.

Since the perimeter of the part covered in gravel is 22 meters, we can use the formula for the perimeter of a square (4s) to find the length of one side of the square. Therefore, the side length of the part covered in grass is 4s = 22, or s = 5.5 meters.

Using the formula for the area of a square (A = s²), we can calculate the area of the grass section of Brooke's yard. The area of the grass section of Brooke's yard is A = s²= 5.5²= 30.25 square meters.

Answer:

  a)  93 cm²

  b)  98 cm²

Step-by-step explanation:

You want the areas of the squares shown in each of the figures.

The Pythagorean theorem tells you the square of the hypotenuse is the sum of the squares of the other two sides of a right triangle.

The square of the hypotenuse is 17² = 289.

The sum of the squares of the other two sides is ...

  shaded square + (14)² = 17²

  shaded square + 196 = 289

  shaded square = 289 -196 = 93 . . . . cm²

Sabcd = 93 cm².

The square of the diagonal is the sum of the squares of the sides. Each of those squares is the area of interest:

  14² = (shaded square) + (shaded square)

  196 = 2(shaded square)

  98 = shaded square

Sabcd = 98 cm².

So on solving the provided question we can say that - Area of prism,

Area, A = 2(wl+hl+hw) = 180 sq units

The definition of a prism in geometry is a polyhedron with an n-sided polygonal base, a second base that is a shifted copy of the first base, and n additional faces (necessarily all parallelograms), with two Connect the corresponding sides of the base. Translations of the base are all cross sections that are parallel to it. A prism is a two-sided, solid, three-dimensional object. It consists of equal cross-sections, flat sides, and identical bases. A prism has faces that are parallelograms or rectangles without bases. A prism is a homogenous, solid, transparent, refracting object enclosed by two planes that are obliquely angled to one another. Two triangular faces and three parallel rectangular faces make up a typical prism. They are constructed of either glass.

a) To evaluate loga 15, we can use the property of logarithms that states logab = loga + logb. Since 15 = 3 * 5, we can use this property to find that loga 15 = loga 3 + loga 5. Since loga 3 = 0.56 and loga 5 = 0.83, we can add these values to find that loga 15 = 0.56 + 0.83 = 1.39.

The power to which a number must be increased in order to obtain additional values is referred to as a logarithm. The easiest approach to express enormous numbers is this manner.

Numerous significant characteristics of a logarithm demonstrate that addition and subtraction logarithms may also be represented as multiplication and division of logarithms.

b) To evaluate loga(2/5), we can use the property of logarithms that states log(a/b) = loga - logb. Since 2/5 = 2*(1/5) we can use this property to find that loga(2/5) = loga2 - loga(1/5). Since loga2 = 0.36 and loga(1/5) = -loga5, we can subtract these values to find that loga(2/5) = 0.36 - 0.83 = -0.47

c) To evaluate loga (8a^4), we can use the property of logarithms that states log (a^n) = nloga. We get, loga (8a^4)=loga 8 + log (a^4)

=> loga 8 + loga (a^4)

The measure of angle L is 66 degrees, which is found using the sum of the internal angle of a triangle. The length is 3.56 units.

A polygon's interior angle is the angle created between its two adjacent sides. Alternately, we may state that the internal angle of a polygon refers to the angle measured at the interior portion of a polygon.

Given that the measure of angle M is 24 degrees and angle K is 90 degrees.

The sum of internal angles of a triangle is 180 degrees, thus:

[tex]\angle M + \angle K + \angle L = 180\\\\24 + 90 + \angle L = 180 \\\\\angle L = 66[/tex]

The length of side LK can be found as follows:

tan 24 = LK / MK

tan 24 = LK / 8

0.44 * 8 = LK

LK = 3.56 units.

The length of LM can be found by applying the Pythagorean theorem.

The domain and range of the given graph function is R.

The equation -3x^2 + 12y^2 = 84 represents an ellipse in the coordinate plane. The standard form of an ellipse is (x^2/a^2) + (y^2/b^2) = 1, where a and b are the lengths of the semi-major and semi-minor axis, respectively.

To put the given equation in standard form, we need to divide both sides by 84, and divide the x^2 and y^2 by the square of their respective coefficient:

(-3/84)x^2 + (12/84)y^2 = 1

This gives us x^2/ (84/-3)^2 + y^2/ (84/12)^2 = 1

Which gives us x^2/28 + y^2/7 = 1

This means that the semi-major axis has a length of 2sqrt(7) and the semi-minor axis has a length of sqrt(7).

The domain of this function is all real numbers, because the x values can take any real value.

The range of this function is also all real numbers, because the y values can take any real value, within the boundaries of the ellipse.

So, the domain and range of the function -3x^2 + 12y^2 = 84 is all real numbers.
