23.) Find the total surface area

Answer:

3 necklaces

Step-by-step explanation:

$40.50-$30.00=$10.50   Subtract her total money and cost of dress

$10.50-$3.50=$6.00  subtract each necklace price from remaining money

$6.00-$3.50=$3.50 keep subtracting price of necklace

$3.50-$3.50=$0  that was 3 necklaces

Answer:

12.8 ft or exactly sqrt 164

Step-by-step explanation:

Pythagoreans is a^2+b^2=c^2

10^2+8^2=164

sqrt 164 = 12.8 ft

Maggie can buy 10 pencils, 5 rubber balls, and 3 yo-yos.

You just divide 5.00 but the price of each item to see how much you can buy without spending too much.

Answer:

No she is not correct .

Step-by-step explanation:

Given

-2(3x-3)=-6x+1

simplify the right hand side

-6x+6 that is not equal to -6x+1

The solution is, the following statement is, False.

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted \triangle ABC. In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane.

here, we have,

given that,

Triangle ABC is similar to triangle WYZ.

now, we get,

Corresponding angles in similar triangles are congruent.

The similarity statement tells you angle B corresponds to angle Y,

so those angles are congruent.

The sines of congruent angles are identical.

so, we have,

 sin(B) > sin(Y) . . . . FALSE

 sin(B) = sin(Y) . . . . true

Hence, The solution is, the following statement is, False.

Answer:

1583362.7 termites

Step-by-step explanation:

A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound

The formula for the volume of a cone

= πr²h/3

Radius = r = 60cm

Height = h = 1.4 m

Converting to centimeters.=

1m = 100cm

1.4m = x

x = 1.4 × 100cm = 140 cm

Volume of the cone = π × 60² × 140/3

527787.5658 cm³

From the above question

1cm³ = 3 termites

527787.5658 cm³ = x

Cross Multiply

x = 3 × 527787.5658

x = 1583362.6974 termites

Approximately.= 1583362.7 termites

Answer:A conical termite mound has a height of 1.4m and a base of radius 60cm if there are three termites per cubic centimeter, how many termites inhabit the mound

[tex]-\frac{25}{12}[/tex]

[tex]-2\frac{1}{12}[/tex]

Answer: Part-to-part

Step-by-step explanation:

This is a part-to-part, because they show part of apples, and part of oranges. This ratio when set up is 4:3. If the ratio was part-to-whole, then the apples would be compared to the total amount of oranges and apples. The ratio for part-to-whole would be 4:7.

Answer:

I chose a box of cereal-------> rectangular prism

see the attached figure

Part 1)List the dimensions of your box. Be sure to include the units (in, cm, ft, etc.).

Length: 20 cm

Width: 8 cm

Height: 32 cm

Part 2).

Describe the shape of the cross-section when the box is cut parallel to the base

the shape of the cross-section would be a rectangle of dimensions

20 cm x 8 cm

Part 3)

What is the surface area of the box?

surface area=2*area of the base+perimeter of the base*height

area of the base=20*8=160 cm²

perimeter of the base=2*[20+8]-----> 56 cm

height=32 cm

surface area=2*160+56*32------> 2,112 cm²

the answer part 3) is

2,112 cm²

Part 4)

What is the surface area of the box if it is scaled up by a factor of 10?

we know that

surface area of the larger box=[scale factor]²*surface area original box

scale factor=10

surface area original box=2,112 cm²

so

surface area of the larger box=10²*2,112-----> 211,200 cm²

the answer part 4) is

211,200 cm²

Part 5)

What is the volume of the box?

volume of the box=L*W*H-----> 20*8*32------> 5,120 cm³

the answer Part 5) is

5,120 cm³

Part 6)

What is the volume of the box if it is scaled down by a factor of 1/10

we know that

volume of the smaller box=[scale factor]³*volume original box

scale factor=1/10

volume original box=5,120 cm³

so

volume of the smaller box=[1/10]³*5,120-----> 5.12 cm³

the answer part 6) is

5.12 cm³

Step-by-step explanation:

Answer:

- The neighbor that has the most amount of fence to put up is: Neighbor A.

- The neighbor that has the least amount of fence to put up is: Neighbor C.

Step-by-step explanation:

To calculate the amount of fence that Neighbor A has to put up, you need to add the following distances:

Convert yards to feet (Remember that :

To calculate the amount of fence that Neighbor B has to put up, you need to use the formula for calculate the circumference of a circle:

Where r is the radius.

In this case, the radius is:

Substituting, you get:

To calculate the amount of fence that Neighbor C has to put up, you need to add the following distances:

Therefore, the neighbor that has the most amount of fence to put up is: Neighbor A.

The neighbor that has the least amount of fence to put up is: Neighbor C.

2(5) + 3 = 13 so (5,1) is not

Answer:

D is the correct answer.

Step-by-step explanation:

1 times 2 is 2 plus 3 is 5, so its not A

2 times 2 is 4 plus 3 is 7 so its not B

and 3 times 2 is 6 plus 3 is 9 so it cant be C either

Therefore its D.

Answer:

-3

Step-by-step explanation:

First, you look at which way it is going. From left to right, the line is going down, so the slope is negative. Change in y is 3 and change in x is 1. From any two points on the line, the y value changes by 3 every time the x value changes by 1.

Answer:

-3

Step-by-step explanation:

slope = rise/run

rise = vertical distance

run = horizontal distance

Step 1. Find two easy to read points on the line. Use points on intersections of grid lines.

For example, choose points (0, -3) and (-1, 0).

Step 2. Start at one point, say (0, -3). We must go to the other point using only vertical and horizontal moves. Go up 3 units. That is a rise of +3. It's positive 3 since up is positive. Now go left 1 unit. That is a run of -1. It is negative because going left is negative.

Step 3.

slope = rise/run

slope = 3/(-1) = -3

Answer: slope = -3

Answer:

The distance from the sailboat to the island where the lighthouse is located is approximately 212.2 yards

Step-by-step explanation:

The distance between the sailboat and the lighthouse is found using trigonometric ratios as follows;

The given parameters are;

The distance from the sailboat to the lighthouse's light = 245 yards

The angle of elevation of angle B = An angle chosen between 25° and 45°

For simplicity, we chose, B = 30°

A right triangle formed with the height of the light house and the horizontal distance of the sailboat from the lighthouse as legs and angle B is the angle adjacent to the horizontal distance of sailboat from the light house

The hypotenuse length = The distance from the sailboat to the lighthouse's light = 245 yards

By trigonometric ratio, in the we have;

[tex]cos\angle B = \dfrac{Adjacent\ leg \ length}{Hypotenuse \ length}[/tex]

The adjacent leg length = The horizontal distance of sailboat from the light house

[tex]\therefore cos (30^{\circ}) = \dfrac{The \ horizontal \ distance \ between \ the \ sailboat \ and \ the \ lighthouse }{245 \ yards}[/tex]

The horizontal distance between the sailboat and the light house = 245 × cos(30°) ≈ 212.176223927

Therefore;

The horizontal distance between the sailboat and the lighthouse ≈ 212.2 yards

Therefore, the distance from the sailboat to the island where the lighthouse is located ≈ 212.2 yards.
