Answer: I think its 30

Step-by-step explanation:

[tex]\cos(\theta+60^{\circ})=\cos \theta \cos 60^{\circ}-\sin \theta \sin 60^{\circ} \\ \\ =\frac{1}{2}\cos \theta-\frac{\sqrt{3}}{2}\sin \theta \\ \\ \therefore a=-\frac{\sqrt{3}}{2}, b=\frac{1}{2}[/tex]

Answer:

259.2 Inches.

Step-by-step explanation:

30*12/5 for one side(length), Multiply by two for the perimeter.

24*12/5 for the width, Multiply by two for the perimeter

144+115.2 = 259.2

Step-by-step explanation:

Answer:

60+4.5pi

Step-by-step explanation:

First find the area of the rectangle alone which is l*w

so 6*10 is 60,

then, you find the area of the semicircle which is 1/2pir^2

so 1/2(pi)(3^2) = 4.5pi

the radius is 3 because its 6/2

then you add it together which is 60+4.5pi

Answer:

Step-by-step explanation:

A of rect. + A of semicircle = Area of the figure

lb + [tex]\frac{\pi r^2}{2}[/tex]

Length of rectangle = 6

Breadth of rectangle = 10

Diameter of semicircle = 6

Radius of semicircle = 3

∴ (6x10) + [tex](\frac{22}{7}[/tex]x[tex]3^2[/tex] x[tex]\frac{1}{2}[/tex])

= 60 + [tex]\frac{99}{7}[/tex]

= 74.14 cm sq

Round off to nearest tenths place = 70 cm sq

Answer:

This looks pretty easy. Is this a trick question or what? I might be wrong but the answer seems to be B. 110 lb.

Step-by-step explanation:

Solution:

Given,

weight of Randy = 50 pounds

weight of his father = 160 pounds

difference in their weights = ?

Now,

difference in their weights =

weight of his father - weight of Randy

= 160 - 50

= 110 pounds

Therefore, the difference in their weights is 110 pounds.

Move up one and right one and one-half.

Move up one and one-half and right three.

Move up two and right three.

Move up one and right two


It would be the 4th one

It would be D, Move up one, and right two. *

Answer:

D option

Step-by-step explanation:

Move up and right two

Because according to the pattern before, (2, 1) is one up and two right to (1, 0.5)

Similarly, for equivalent ratio, we'll apply the same pattern.

Answer: undetermined

Step-by-step explanation: in order to find volume you need 3 dimensions the x y and z, you only have x and y no z so it’s a 2d object. If the width is also 13ft then 13x13x4.5= 760.5ft^3

Answer:

301.6

Step-by-step explanation:

area of circle is pi*r^2

pi*14^2

196pi

pi*10^2

100pi

196pi-100pi=96pi

= around 301.6

Answer:

Step-by-step explanation:

(25) [tex]x^2 + 24x + c[/tex]

24÷2 = 12

∴ [tex]x^2 + 12x + 12x + c[/tex]

Now, 12 x 12 = 144

∴ [tex]x^2 + 12x +12x + 144[/tex]

--> [tex]x^2 + 24x + 144[/tex]

Hope you understood 25!

Answer:

469.1

Step-by-step explanation:

first find parallelogram area and then 1/2 circle area

parallelogram area=lh

area=12*26

area=312

area of circle=pi*r^2

r=20/2=10

pi*10^2

100pi for full circle

100pi/2=50pi=half circle

50pi=157.1

157.1+312=469.1

Answer:

B- 44%

Step-by-step explanation:

original - new / original

50-22/50

28/50

0.44

0.44 as a percent is 44

Answer:

= 44%

Step-by-step explanation:

50 - 28 = 22

22/50 = 0.44%

0.44 * 100 = 44%

Answer:

The surface area of a cylinder with radius "r" and height "h" is given by: 2πrh + 2πr^2.

So, for the given cylinder, the surface area can be calculated as:

surface area = 2 * π * 3^2 * 7 + 2 * π * 3 * 7

= 2 * π * 9 * 7 + 2 * π * 3 * 7

= 126π + 42π

= 168π

Rounding the answer to the nearest tenth, the surface area of the cylinder is approximately 527.1 square feet.

Answer:

see graph below

Step-by-step explanation:

y = 3x

We can plot two points on the graph and then make the line.

Let x = 0

y = 3

(0,0)

Let x = 1

y = 3*1 = 3

(1,3)

21

Step-by-step explanation:

1/2×8×6=24

3×1=3

24-3=21

Answer:

it should be 21

Step-by-step explanation:

Note that [tex]\cos a=\frac{4}{5}[/tex]. Since [tex]-\pi<a<0[/tex], [tex)\sin \alpha<0[/tex]. So, by the Pythagorean theorem, [tex]\sin \alpha=-\frac{3}{5}[/tex].

[tex]c=\cos \left(a+\frac{\pi}{6} \right) \\ \\ c=\cos a \cos \frac{\pi}{6}-\sin a \sin \frac{\pi}{6} \\ \\ c=\frac{4}{5} \cdot \frac{\sqrt{3}}{2}+\frac{3}{5} \cdot \frac{1}{2} \\ \\ c=\frac{4\sqrt{3}+3}{10} \\ \\ \therefore 10c=4\sqrt{3}+3[/tex]

Note that [tex]\cos b=\frac{4}{5}[/tex] and that [tex]0<b<\pi[/tex], meaning [tex]\sin b>0[/tex]. So, by the Pythagorean identity, [tex]\sin b=\frac{3}{5}[/tex].

[tex]d=\cos \left(b+\frac{\pi}{6} \right) \\ \\ d=\cos b \cos \frac{\pi}{6}-\sin b \sin \frac{\pi}{6} \\ \\ d=\frac{4}{5} \cdot \frac{\sqrt{3}}{2}-\frac{3}{5} \cdot \frac{1}{2} \\ \\ d=\frac{4\sqrt{3}-3}{10} \\ \\ \therefore 10d=4\sqrt{3}-3[/tex]

Answer:

it is 11x+25x=180

Step-by-step explanation:

the sum of the angles  of a triangle is 180

so, 11x+25x+9x=180

.11x+34x=180 true

34x=25x+9x

.36x+9x=180 true

36x=11x+25x

.11x+25x+9x=180 true

.11x+25x=180 false because the angle at F hasn't been added to the equation.

Step-by-step explanation:

Answer:

95 * 5

Step-by-step explanation:

we know, a² - b² = (a + b) (a - b)
So, we can rewrite 50² - 45² using the above equation
as (50 + 45)(50-45)
which is, 95 * 5 [Your product]
= 475

Answer: 475

Step-by-step explanation:

Using identity: [tex]a^2 - b^2[/tex] = (a+b)(a-b)

--> (50+45)(50-45)

= 95 x 5

= 475

Answer:

Step-by-step explanation:

A possible third length of the copper pipe that will make a triangle is 17 centimeters long.

This can be determined by using the triangle inequality theorem, which states that the sum of the lengths of any two sides of a triangle must be greater than the length of the third side.

For example, if the 4 cm pipe represents one side and the 13 cm pipe represents another side of the triangle, in order to make a triangle, the third side must be less than the sum of the other two sides (4 cm + 13 cm) and greater than the difference of the other two sides (13 cm - 4 cm). Therefore, the third side must be between 9 cm and 17 cm.

17 cm is the only length within this range that can make a triangle with 4 cm and 13 cm.

Answer: The possible length of the third triangle is 17

Step By Step Explanation: When you add 4 + 13 = 17 and 4 and 13 were the lengths of the other copper pipes.
