Answer:

1440°

Step-by-step explanation:

From the 8 sided diagram, 8 triangles can be obtained. 1 triangle adds up to 180° thus for the diagram ,sum of interior will be 180°×8=1440°

Answer:

sry i dont know sorry please

Answer:

m<D = 26

Step-by-step explanation:

<D = x

x + 122 + 32 = 180

x + 154 = 180

x = 180 - 154

x = 26

Answer:

Step-by-step explanation:

<D + 122° + 32° = 180° ( being sum of angles of triangle )

< D = 180° - 154°

< D = 26°

Step-by-step explanation:

Answer:

please send the figure.

Answer:

lets say you where multiplying by 2

2+ 2=4 so that would mean 2x2 is 4

and so on and so on

Step-by-step explanation:

ok so an equation like 2x3 is the same as 2+2+2.

Answer:

B

Step-by-step explanation:

Given 2 sides of a triangle then the third side is in the range

difference of 2 sides < AB < sum of 2 sides , that is

54 - 27 < AB < 54 + 27

27 < AB < 81 → B

Answer:

C

Step-by-step explanation:

C will have the least value with -99.

A would be 1/100, which is 0.01, which is small, but larger than -99.

B would be 10/100, which is 0.1, which is larger than A.

C is 1-100, which equals -99.

D is 10-100, which equals -90. -99 is smaller than -90.

Answer:

c) 1 - x

Step-by-step explanation:

x = 100

a) [tex]\frac{1}{x}[/tex] ⇒ [tex]\frac{1}{100}[/tex]

answer ⇒ 0.01

b) [tex]\frac{10}{x}[/tex] ⇒ [tex]\frac{10}{100}[/tex]

answer ⇒ 0.10

c) 1 - x ⇒ 1 - 100

answer ⇒ -99

d) 10 - x ⇒ 10 - 100

answer ⇒ -90

Answer: 188.4 cm

Step-by-step explanation:

Given

the radius of the circle is [tex]r=30\ cm[/tex]

Also, circumference is given by [tex]P=2\pi r[/tex]

Putting values

[tex]\Rightarrow P=2\times 3.14 \times 30=188.4\ cm[/tex]

The circumference of the circle is [tex]188.4\ cm[/tex]

Answer:

b) 500

16x = (141)^2 - (109)^2

or, 16x = 19881 - 11881

or, x = 8000/16=500

Answer:

[tex]h=-15[/tex]

Step-by-step explanation:

[tex]\frac{h}{6-1}=-3[/tex]

Simplify:

[tex]\frac{1}{5} h=-3[/tex]

Multiply both sides by 5:

[tex]5\times(\frac{1}{5}h)=(5)\times(-3)\\h=-15[/tex]

h = -15 is your final answer.

Answer:

Step-by-step explanation:

[tex] \frac{h}{6 - 1} = - 3 \\ \: \: \: \: \: \: \frac{h}{5} = - 3 \\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: h = 5 \times ( - 3) \\ \: \: \: \: \: \: \: \: \: h = - 15[/tex]

Answer: y = 500 * ( 1 + 0.75%) ^ (t * 12)

Step-by-step explanation:

Formula for calculating the amount of money in an account as a result of compound interest is:

Balance = Amount * ( 1 + rate) ^ no. of periods

This interest is compounded monthly so has to be converted to a monthly rate:

= 9% / 12

= 0.75%

t is in years so has to be converted as well to months:

= t * 12 months

Function is therefore:

y = 500 * ( 1 + 0.75%) ^ (t * 12)

Answer:

$603.04

Step-by-step explanation:

The Compound Amout formula is A = P(1 + r)^t, where:

P is the principal (initial deposit), r is the annual interest rate as a decimal fraction, and t is the time period in years.

In this particular case, the Compound Amount is:

A  = ($450)(1 + 0. 05)^6 = ($450)(1.34) = $603.04

Answer:

B = (10, -4),  D = (58/9, -2)

Step-by-step explanation:

Point C(3.6, -0.4) divides in the ratio 3 : 2. If the coordinates of A are (-6, 5), the coordinates of point B are ___ . If point D divides in the ratio 4 : 5, the coordinates of point D are ___ .

Solution:

If point O(x, y) divides line segment AB with endpoints at A(x₁, y₁) and B(x₂, y₂) in the ratio n:m, then:

[tex]x=\frac{n}{n+m}(x_2-x_1)+x_1 ;\ y=\frac{n}{n+m}(y_2-y_1)+y_1[/tex]

Since point C divides AB in the ratio 3:2. Let the coordinates of B be (x₂, y₂). Hence:

[tex]3.6=\frac{3}{3+2}(x_2-(-6))-6\\\\9.6=\frac{3}{5}(x_2+6) \\\\x_2+6=16\\\\x_2=10\\\\\\-0.4=\frac{3}{3+2}(y_2-5)+5\\\\-5.4=\frac{3}{5}(y_2-5) \\\\y_2-5=-9\\\\y_2=-4[/tex]

B = (10, -4)

D divides CB in the ratio 4:5. Let D = (x, y). Hence:

[tex]x=\frac{4}{4+5}(10-3.6)+3.6 \\\\x=\frac{58}{9} \\\\\\y=\frac{4}{4+5}(-4-(-0.4))+(-0.4)\\\\y=-2[/tex]

Hence D = (58/9, -2)

Step-by-step explanation:

[tex] \frac{42}{14} = \frac{x}{12} \\ x = \frac{42 \times 12}{14} \\ x = \frac{504}{14} \\ x = 36[/tex]

Answer: [tex]31.24\ ft[/tex]

Step-by-step explanation:

Given

The height of a man is 5 ft

Distance between man and tree is 42 ft

the angle of elevation is [tex]32^{\circ}[/tex]

Suppose h is the height of the tree

[tex]\Rightarrow \tan 32^{\circ}=\dfrac{h-5}{42}\\\\\Rightarrow h-5=26.24\\\Rightarrow h=31.24\ ft[/tex]
