1.

You can use the sine rule

a / sinA = b / sinB

Substitute the values in:

15 / sin112 = b / sin33

Multiply both sides by sin(33) to get b by itself

b = (15 / sin112) x sin33

Calculate this to get your answer of:

BC = 8.8 cm

2.

You can also use the sine rule here

sinA / a = sinB / b

Sub your values in:

sin84 / 32.4 = sin(y) / 21

Multiply both sides by 21 to isolate sin(y)

(sin84 / 32.4) x 21 = sin(y)

Calculate sin(y)

sin(y) = 0.6445975248

You now need to sin-1 this value to get u:

y = 40.13550596

To 1d.p, y = 40.1 degrees

Answer:

To find the surface area of a cuboid, add the areas of all 6 faces. We can also label the length (L), width (w), and height (h) of the prism and use the formula, SA=2lw+2lh+2hw, to find the surface area.

To find the total surface area of a figure, we need to add all the areas of every surface and add them.

What is the surface are?

The surface area of a figure is the total area of the outside of the figure.

If the surface area of a particular figure is just only one type (ex: sphere), then the calculation of the surface area will be easier.

If the surface of a figure consists of different types of geometrical figure(ex: cone), then we need to find the area of each and then add them.

Degree of length=1

Degree of width=1

Degree of height=3

Degree of volume=5

The [SUM] of the degree of each factor is the degree of the product

Why does this make sense Answer is C

Since a linear function has a degree of 1, hence the degree of the length, width and height is 1. The degree of the volume is 3

The degree of an equation is the power of the leading variable.

Given the following measures

length = 4x - 1

width = x

height = x -3

Since a linear function has a degree of 1, hence the degree of the length, width and height is 1. The degree of the volume is 3

Answer:

The total distance is  [tex]d_T = 6250 \ m[/tex]

Step-by-step explanation:

From the question we are told that

     The distance from bailey start point to her friends house is  [tex]d = 3 \ km = 3*1000 = 3000 \ m[/tex]

       The distance covered going to and from the park is [tex]d_2 = 250 m[/tex]

The total distance covered is mathematically evaluated as

         [tex]d_T = (2 * d_1) + d_2[/tex]

Substituting values

          [tex]d_T = (2 * 3000) + 250[/tex]

          [tex]d_T = 6250 \ m[/tex]

Answer:

Volume of sphere is 2,304 pi ft^3

Surface area of sphere is 576 pi ft^2

Step-by-step explanation:

When we talk of a great circle, we are talking of a circle around the sphere that has the same radius as the sphere.

Mathematically the area of the great circle is pi * r * r

now pi * r^2 = 144 pi

divide both sides by pi

r^2 = 144

r^2 = 12^2

since power are equal, we equate bases and the radius of the circle is thus equal to 12 feet

Now to calculate the volume of the sphere,

We know that the volume of a sphere is ;

V = 4/3 * pi * r^3

V = 4/3 * pi * 12^3

V = 4 * pi * 4 * 12^2 = 2304 pi ft^3

The surface area of the sphere is mathematically equal to 4 * pi * r^2

= 4 * pi * 12^2 = 576 pi ft^2

Answer:

Each pizza costs $12.

Each drink costs $2.

Step-by-step explanation:

This question can be solved using a system of equations.

I am going to say that:

x is the cost of each pizza.

y is the cost of each drinks.

The Talbot family got 2 pizzas and 4 drinks for $32.

This means that [tex]2x + 4y = 32[/tex]

The Martinez family got 3 pizzas and 8 drinks for $52.

This means that [tex]3x + 8y = 52[/tex]

Using the addition method, multiplying the first equation by -2.

-4x - 8y = -64

3x + 8y = 52

-4x + 3x - 8y + 8y = -64 + 52

-x = -12

x = 12

Each pizza costs $12.

2x + 4y = 32

2x + 4y = 32

4y = 32 - 2x

4y = 32 - 2*12

4y = 8

y = 2

Each drink costs $2.

Answer:

10 hours

Step-by-step explanation:

We can actually solve this problem simply as if it were an equation instead of an inequality. We have:

15 + 8h ≤ 95

Subtract 15 from both sides:

8h ≤ 95 - 15

8h ≤ 80

Divide by 8 from both sides:

h ≤ 80/8

h ≤ 10

So, the number of hours cannot exceed 10, which means the maximum number of hours Susie can rent is 10 hours.

Answer:

351

Step-by-step explanation:

Complete question :

Vanilla= 36

Chocolate=21

Strawberry=24

Chocolate Chip=39

SOLUTION:

39 chocolate chip to 200 students = x chocolate chip to 1800 students

39/200 = x / 1800

Solving for 'x'

(200)(x) = (39)(1800)

200x = 70200

x = 70200/200

x = 351

OR

39 out of 200 picked chocolate chip

therefore, 39/200 = 0.195 = 19.5%  ( 32.5% chose chocolate chip)

19.5% of 1800 = 0.195(1800) = 351 students

Answer:

see below

Step-by-step explanation:

A: radius of 12 ft

    Changing to meter

 12 ft * .305 m/ ft =3.66 meter

The radius is 3.66 meters

The diameter is twice the radius = 2*3.66 =7.32 meters

The circumference is

C = pi*d = 3.14 * 7.32 =22.9848 = 22.98 meters

B diameter is 7.5 meters

Pool B has a bigger diameter

C = pi * d = 3.14 * 7.5m = 23.55 meters

The difference is .57 meters

Answer:

7.32

B

Larger/greater

0.57

Step-by-step explanation:

Diameter = 2 × radius

= 2 × 12 = 24 feet

24 × 0.305 = 7.32 meters

7.5 > 7.32

So the diameter of pool B is greater

Difference in circumferences:

(3.14 × 7.5) - (3.14 × 7.32)

23.55 - 22.98

0.57 meters

The equation to find the sum of interior angles of a n-sided polygon is:

(n - 2) * 180

So, we don't know what n is but we can make it look like this:

(n - 2) * 180 = 8,280

Solve for n.

(n - 2) * 180 = 8,280

~Divide 180 to both sides

(n - 2) * 180/180 = 8,280/180

~Simplify

n - 2 = 46

~Add 2 to both sides

n - 2 + 2 = 46 + 2

~Simplify

n = 48

Therefore, the polygon has 48 sides.

Best of Luck!

-The volume of a cylinder can be either:

In terms of pi: [tex]54\pi[/tex]

             or

Using 3.14 for pi: [tex]169.646[/tex] [tex]in^3[/tex]

Step-by-step explanation:

Use the formula for the volume of a cylinder and use the given radius and height for the formula:

[tex]V = \pi r^2 h[/tex]

[tex]V = \pi 3^26[/tex]

Then, solve the formula:

[tex]V = \pi \times 3^2 \times 6[/tex]

[tex]V = \pi \times 9 \times 6[/tex]

[tex]V = \pi \times 54[/tex]

[tex]V = 54\pi \approx 169.646[/tex]

-So, the answers would be:
