Answer:

Set your calculator to degree mode.

Using the Law of Cosines:

37^2 = 23^2 + 20^2 - 2(23)(20)(sin C)

1,369 = 929 - 920sin(C)

440 = -920sin(C)

sin(C) = -11/23

C = sin^-1 (-11/23) = 151.4°

The proportion of the tapestries' height to width is 3:2, which means the height is 1.5 times the width.

To find the proportion of the tapestries' height to width using whole numbers and ratio notation, we need to divide the height of the tapestry by its width.

The height of the tapestry is 1.5 meters, and the width is 1 meter. Therefore, the proportion of the tapestry's height to width is

1.5 meters / 1 meter = 1.5 : 1

We can simplify this ratio by dividing both sides by 1, which gives

1.5 : 1 = 3/2 : 1

Therefore, the proportion of the tapestry's height to width using whole numbers and ratio notation is 3:2.

The surface area of the rectangular prism is 2600 square inches.

Surface area is the total area that the surface of a 3-dimensional object covers. In order to find the surface area of a rectangular prism, we need to find the area of each of its faces and add them together.

The rectangular prism in question has dimensions of 23 inches by 8 inches by 18 inches. Looking at the net, we see that there are three pairs of identical rectangles: the top and bottom faces, the front and back faces, and the left and right faces. Each of these rectangles has dimensions of 23 inches by 8 inches.

Therefore, the surface area of the rectangular prism can be calculated as:

Area of top and bottom faces = 2 * (23 in. * 8 in.) = 368 square inches

Area of front and back faces = 2 * (18 in. * 8 in.) = 288 square inches

Area of left and right faces = 2 * (23 in. * 18 in.) = 828 square inches

Total surface area = 368 + 288 + 828 = 2600 square inches

Step-by-step explanation:

56.54867 (the area of the bigger half circle) + 14.137165 (the area of the smaller half circle + 96 (the area of the rectangle) = 166.685835 (rounded up is 166.7 (B)).

The measure of the arc angles CA and AD are 216° and 46° respectively, while the angle m∠C is equal to 36°.

The angle subtended by an arc of a circle at it's center is twice the angle it substends anywhere on the circles circumference. Also the arc measure and the angle it subtends at the center of the circle are directly proportional.

Diameter BD bisects the angle m∠ABC and the triangles BQC and BQA are identical isosceles triangles so;

m∠QBC = 72/2 = 36°

m∠BQC = 180 - 2(36)°

m∠BQC = 108, also m∠AQB = 108° so;

arc angle CA = 2(108)° = 216°

arc angle CD = arc angle AD so;

arc angle AD = 46°

angles m∠QBC and m∠BCQ are base angles of an isosceles and they are equal so;

m∠C = 36°

The number of minutes of local landline calls is 132 min.

We are given that;

To find the number of minutes of local landline calls, we need to rearrange the tariff structure formula to solve for n in terms of Total and m. We also need to substitute the given values of Total and m.

Total = nx 12c/min +mX R1,10/min + R75,75

n = (Total - m x R1,10/min - R75,75) / (12c/min)

Total = R131.19

m = number of minutes of calls to cellphones = 36 min

n = (131.19 - 36 x 1.10 - 75.75) / 0.12

Answer:

As we have shown that both line segments PN and PM are equal to (1/2)MN, and hence they are equal in length to each other.

Given that point P lies on the perpendicular bisector l of line segment MN, we know that line segment PN and line segment PM are both equal in length to the distance between point P and the midpoint of MN, which we will call point O. This is because the perpendicular bisector of a line segment passes through the midpoint of the segment, and any point on the perpendicular bisector is equidistant from the endpoints of the segment.

Let us call the length of line segment PM "x". Then, we can express the lengths of line segments PN and PO in terms of x as well. Since P is equidistant from the endpoints of MN, we know that line segment PN has the same length as line segment PO, which is half the length of MN. We can express this relationship mathematically as:

PN = PO = (1/2)MN

Similarly, we can express the length of line segment PM in terms of the length of PO, which is also equal to (1/2)MN. Since line segment PM is equal in length to the distance between point P and the midpoint of MN, we know that:

PM = PO = (1/2)MN

Therefore, we have proved that PM = PN.

Option C is the correct answer.

We have,

Elimination is the best method for solving this system of equations since we can eliminate the x-term by adding the two equations together.

This will give us a single equation in y, which we can then solve for y, and use to find the value of x.

In this case, we can eliminate the x term by adding the equations.

3x + 2y = 4

-3x + y = 2

If we add the two equations, the x term will cancel out:

3x + 2y = 4

(-3x + y = 2)

0x + 3y = 6

Simplifying, we get:

3y = 6

y = 2

Now that we have found the value of y, we can substitute it into one of the equations to find the value of x.

Let's use the second equation:

-3x + y = 2

-3x + 2 = 2

-3x = 0

x = 0

Therefore, the solution to the system of equations is (x, y) = (0, 2).

Answer:

160 biscuits × 3 grams butter/biscuit = 480 grams butter

160 biscuits × 2 grams sugar/biscuit = 320 grams sugar

Katie needs 320 grams sugar.

Kate needs 270g of sugar to make the maximum number of biscuits possible.

Any relationship that is always in the same ratio and quantity which vary directly with each other is called the proportional.

Now, Based on the ratio of flour, butter, and sugar of 5:3:2, we can determine that Kate needs;

⇒ 800g + 550g

= 1350g of the mixture.

Hence, For find out the amount of sugar needed, we need to determine the proportion of sugar in the mixture.

We can do this by adding up the ratio numbers;

(5+3+2) = 10.

Then we can divide each ratio number by the total (10) to get the proportion of each ingredient.

So the proportion of sugar in the mixture is 2/10. To find out how much sugar Kate needs, we can set up a proportion:

2/10 = x/1350

We can solve for x by cross-multiplying:

2 × 1350 = 10x

2700 = 10x
x = 270

Therefore, Kate needs 270g of sugar to make the maximum number of biscuits possible.

The value of "c" in this triangle is approximately 154.2 units long.

The given information is a side length of 61 and two angles, one of which is 142 degrees. To solve for the unknown side length "c", we can use the law of sines, which states that the ratio of the length of a side of a triangle to the sine of the angle opposite that side is the same for all three sides. In other words:

a/sin(A) = b/sin(B) = c/sin(C)

Where a, b, and c are the side lengths of the triangle, and A, B, and C are the angles opposite those sides.

In this problem, we know the side length "a" is 61 and the angle opposite that side is 63 degrees. We also know the angle opposite the unknown side "c" is 142 degrees. Using the law of sines, we can write:

61/sin(63) = c/sin(142)

Now we can solve for "c" by multiplying both sides by sin(142) and then dividing by sin(63):

c = (61*sin(142))/sin(63)

Using a calculator, we find that c is approximately 154.2. Rounding to the nearest tenth, we get:

c ≈ 154.2 to the nearest tenth.

Answer:

the probability of selecting a quarter or a nickel is 0.495 or 49.5%.

Step-by-step explanation:

The probability of selecting a quarter or a nickel can be found by adding the probability of selecting a quarter to the probability of selecting a nickel. Since the coins are chosen randomly, the probability of selecting a coin from the jar is the number of coins of that type divided by the total number of coins in the jar.

So, the probability of selecting a quarter is:

P(quarter) = number of quarters / total number of coins

P(quarter) = 80 / (70 + 100 + 80 + 50)

P(quarter) = 0.32

Similarly, the probability of selecting a nickel is:

P(nickel) = number of nickels / total number of coins

P(nickel) = 70 / (70 + 100 + 80 + 50)

P(nickel) = 0.175

To find the probability of selecting a quarter or a nickel, we add these probabilities:

P(quarter or nickel) = P(quarter) + P(nickel)

P(quarter or nickel) = 0.32 + 0.175

P(quarter or nickel) = 0.495

Therefore, the probability of selecting a quarter or a nickel is 0.495 or 49.5%.
