Find the measures of angles CFE and DEF.​

Answer:

The answer is 4cm.

Step-by-step explanation:

Given:

Height= 15cm

The volume of the Cylindrical bottle= 753.6

They have said to use π= 3.14

We are supposed to find r.

-------------------------------------------------------------

Volume of cylinder= πr²h

now substitute teh values given in the formula..we will get:

753.6 = 3.14× r²× 15

After u solve it , you will get

r²= 16

∴r = √16= 4cm

So,  the radius of the bottle is 4cm

Answer:

833

Step-by-step explanation:

First find the 15% of 56,105;

[tex]\frac{15}{100}[/tex] * 56,105 = x

0.15 * 56,105 = x

882 = x

Now subtract 15% of 56,105 from 56,105;

15% of 56,105 = 882

now;

56,105 - 882 = 833

Answer:

0.571428571429 grams per cm³

Step-by-step explanation:

density = mass/volume

Let’s calculate the volume V of the pyramid :

V = (1/3)×base×height

   = (1÷3)×(5×7)×9

   = 105 cm³

Then

The density = mass/volume

                    = 60÷105

                    = 0.571428571429

Answer:

F(x) < 6

Step-by-step explanation:

[tex]\sqrt{(x^2 + 6x +9)} = \sqrt{(x+3)(x+3)} = \sqrt{(x+3)^2\\}[/tex]

This can be simplified to (x+3) and so if x is less than 3, f(x) is less than 6

Answer:

£6633.04

Step-by-step explanation:

Compound interest is worked out by using decimal multipliers on a calculator basically,

so,

6000 x 1.034 (because 3.4% = 0.034)

but you want it for three years so you would do

6000 x 1.034 x 1.034 x 1.034

Answer:

Option A, [tex]385.0\ ft^2[/tex]

Step-by-step explanation:

Step 1:  Determine the area of the base

[tex]A = l * w[/tex]

[tex]A = 11\ ft * 11\ ft[/tex]

[tex]A = 121\ ft^2[/tex]

Step 2:  Determine the area of the triangles

[tex]A = \frac{h * b}{2}[/tex]

[tex]A = \frac{12\ ft * (11\ ft / 2)}{2}[/tex]

[tex]A = \frac{12\ ft * 5.5\ ft}{2}[/tex]

[tex]A = \frac{66\ ft^2}{2}[/tex]

[tex]A = 33\ ft^2[/tex]

There are two of these triangles per side which means that there are 8 of these triangles in total.  

[tex]33\ ft^2 * 8[/tex]

[tex]264\ ft^2[/tex]

Step 3:  Determine the surface area

[tex]SA = 121\ ft^2 + 264\ ft^2[/tex]

[tex]SA = 385\ ft^2[/tex]

Answer: Option A, [tex]385.0\ ft^2[/tex]

Answer:

Area = 144 ft^2

Step-by-step explanation:

Remark

Use the Pythagorean theorem to find the length of the legs. Then multiply them together and divide by 2.

Equations

a^2 + a^2 = c^2

Area = (1/2) * a^2

Givens

c = 24

Solution

Remember that an isosceles triangle has 2 equal sides. Both legs of the triangle are equal to a.

a^2 + a^2 = c^2              Combine

2a^2 = 24^2                   Expand

2a^2 = 576                    Divide by 2

2a^2/2= 576/2              

a^2 = 288                      You might just as well leave this. go to area

Area = 1/2 (288)

Answer: Area = 144 ft^2

The true statement about the distribution of any variable model around the mean is (D) The distribution of the variable is the same shape as the distribution of its residual

From the question, we understand that the distribution of the model is based on its mean or average value.

The above means that the upper and the lower deviations are balanced.

Hence, the true statement about the distribution of any variable model around the mean is (D)

Answer:

Milk Glass A can hold more milk.

Step-by-step explanation:

This problem mostly relies on the diameter of the milk glass.

To solve the problem, we'll find the volume of each glass as though it were a cylinder.

First, we start with the area of the base of each cylinder.

Using the formula [tex]\pi r^{2}[/tex], we can find the area of each base.

Note that r represents radius, which is half of the diameter, d.

The area of the base on Milk Glass A can be found with: [tex]\pi 1.75^2[/tex] which equals 9.62 inches squared.

The area of the base on Milk Glass B can be found with: [tex]\pi 0.75^2[/tex] which equals 1.77 inches squared.

Now that we have the area of each base, we just multiple the area by the height to get the full volume.

The volume of Milk Glass A can be found by multiplying [tex]9.62*4[/tex] which equals 38.48 cubic inches.

The volume of Milk Glass B can be found by multiplying [tex]1.77 *5[/tex] which equals 8.85 cubic inches.

Therefore, the larger answer of 38.48 cubic inches means Milk Glass A can hold more milk.

Answer:

25.7 m

Step-by-step explanation:

Semicircles are half circles that are divided at the diameter.

We want to find the semicircle arc.

To do this, just find the circumference of the circle and then divide by 2.

Circumference formula:

2rπ or Dπ

10π = 31.4

31.4 / 2 = 15.7

Now, we have to find the straight line part of the semicircle. The length of that straight line is the diameter. We already know that the diameter is 10.

Add

15.7+10 = 25.7

Answer:

  (b)  Length = 30 feet, width = 20 feet

Step-by-step explanation:

The scale factor is applied to the drawing dimensions to find the actual dimensions.

__

  length = (6 cm) × (5 ft)/(1 cm) = 30 ft

  width = (4 cm) × (5 ft)/(1 cm) = 20 ft

_____

Additional comment

You can also write the scale factor as part of a proportion:

  5 ft : 1 cm :: x ft : 6 cm

Multiplying by 6 cm gives

  (5 ft)(6 cm)/(1 cm) = x ft = 30 ft . . . . as above
