Step-by-step explanation:

Answer:

BD = 3.2.

CD = 2.4.

Step-by-step explanation:

By Pythagoras:

AB^2 = 3^2 + 4^2 = 25

AB = 5.

Triangles ADC and ACB are similar, so

AC / AB = AD / AC

3 / 5 = AD / 3

AD = 3*3/5

AD =  9/5 = 1.8

So BD = 5 - 1.8

= 3.2.

CD^2 = AC^2 - AD^2 (Pythagoras)

CD^2 = 3^2 - 1.8^2 = 5.76

CD = 2.4.

Answer:

x = [tex]\frac{in (8)}{in (36)}[/tex]  if you consider doing decimal form x = 0.58027921. . .

Step-by-step explanation:

Take logarithm of both sides of the equation to remove the variable from the exponent.

Answer:

62  square cm

Step-by-step explanation:

The whole rectangle    12X10 = 120

Now subtract 2 restangles:

5x8 =40

6x3 =18

30+18= 58

120-58 =62

Answer: 62

The required answer for this question.

Answer and Step-by-step explanation:

Definitions:

Obtuse - Angles that are greater than 90 degrees, but shorter than 180 degrees.

Acute - Angles that are less than 90 degrees but greater than 0 degrees.

Right - Angles that are exactly 90 degrees.

1. Obtuse

2. Right

3. Acute

4. Right

5. Obtuse

6. Acute

7. Obtuse

8. Acute

9. Right

#teamtrees #PAW (Plant And Water)

All the angles equals 360°.

The best way to find x without guessing is to add everything and make an equation.

x°-46°+x°+x°-35°+1/2x°=360°

Add like terms.

3 1/2x°-81°=360°

3.5x°=441

x=441/3.5

x=126

Answer:

416 cm2

Step-by-step explanation:

The formula for surface area of prism.

2Ab+ Pb*h

2(1/2)(12)(8)+ 32*10

= 96+320

= 416 cm2

Answer:

1/2

Step-by-step explanation:

Answer:

length = 10

Step-by-step explanation:

Volune =  L W H

H=40

W=8

L=X

40*8*X = 3200

320 X = 3200

X = 10

Volume :      40 x 8 x10 = 3200

Answer:

[tex] \frac{20}{24} = \frac{22}{x + 22} \\ 24 \times 22 = 20x + 20 \times 22 \\ 20x = 4 \times 22 \\ x = 88 \div 20 = 4.4[/tex]

Answer:

x=±√9 or x= 3, x=-3

Step-by-step explanation:

The problem requires us to find the x.

So we must isolate the variable, as so-

[tex]5x^2-45=0\\5x^2=45[/tex] (add 45 to both sides)

Now we can divide both sides by -

[tex]5x^2=45\\x^2=9[/tex]

Now we must square root both sides to find the root of x.

[tex]\sqrt{x^2} =\sqrt{9}[/tex]

x=±√9

or x= 3, x=-3

[tex]38 + 7x - 21 = 9x + 9[/tex]

Combine like terms.

[tex]17 + 7x = 9x + 9[/tex]

Eliminate a x.

[tex]17 = 2x + 9[/tex]

[tex]8 = 2x[/tex]

[tex]x = 4[/tex]

38 + 7x - 21 = 9x + 9

7x + 17 = 9x + 9

Subtract both sides 9

7x + 17 - 9 = 9x + 9 - 9

7x + 8 = 9x

Subtract sides 7x

7x - 7x + 8 = 9x - 7x

8 = 2x

Divide both sides by 2

8 ÷ 2 = 2x ÷ 2

x = 4

Answer:

C. 62x+239=672

Step-by-step explanation:

X represents hours , which means 62 miles per hours equals 62x. Since Ed has already traveled 239 miles the opposite would be to add in order to subtract in the equation. 672 would be the equivalent of traveling 672 miles in x hours.

Answer:

169.4ft^2

Step-by-step explanation:

Area of right triangle= base x height /2

Area of right triangle= 24.2x (7x2) /2

Area of right triangle= 24.2x (14) /2

Area of right triangle= 24.2x (14) /2

Area of right triangle= 169.4ft^2

r = 2

The volume of a cone can be found using the following equation

[tex]V = r^2\frac{h}{3} \pi[/tex]

After putting in the information that we already know we get

[tex]16\pi = r^2\frac{12}{3} \pi \\16\pi = r^2(4) \pi \\4 = r^2\\ r = 2\\[/tex]

For proof's sake, we can try the equation again with the information we know

[tex]V = r^2\frac{h}{3} \pi \\V = 2^2\frac{12}{3} \pi \\V =4(4) \pi \\V = 16\pi[/tex]

Answer:

4^5=x

x= 1045

Step-by-step explanation:

4 to the power of 5 is 1045:)

Answer:

The base of the log is the same as the base of the exponential form and in our case the base is 4. The value of the exponent is what the log is equal too and in our case it is 5. We already know the base is 4 and we want to raise it to the exponent of 5 so we get

x=45 *five on top*

x=1024
