Given the sequence 10, 20, 40, 80,.... find 25th term​

Answer: Figure A to Figure B is a scale factor of 0.5

Step-by-step explanation:

It's not too hard to figure out scale factor, since the two shapes are the same aside from their scale. Notice how Figure A is 4 units tall, and that Figure Bis 2 units tall. From one figure to another, use the equation Figure B/Figure A to find the scale factor. Although you won't really need to memorize all this, you can count the amount of units on your fingers and figure it out from there.

Answer:

what is the question

Step-by-step explanation:

Answer:

1442.9 = 1.4429 x 10 ^1000

Step-by-step explanation:

PEMDAS

4.3 × 107 + 9.1 × 108 = _____ x 10 ^----

(4.3 × 107) + (9.1 × 108) = _____ x 10 ^---

460.1 + 982.8 = _____ x 10 ^----

1442.9 = 1.4429 x 10 ^1000

This is the right answer, I think you may have forgotten to put the ^.  

Answer:

9.53 × 108

Step-by-step explanation:

Make sure both numbers have the same exponent

4.3 × 107 = 0.43 × 108

Then add the coefficients

0.43 × 108 + 9.1 × 108 = 9.53 × 108

Answer:

0.4

Step-by-step explanation:

if u reduce that fraction it would be 4/10 which is 0.4 in decimal form

Answer:

f(g(3)) = 26

Step-by-step explanation:

f(g(3))

g(3) = 2x + 3

= 2(3) + 3

= 6 + 3

= 9

f(9) = 3x - 1

= 3(9) - 1

= 27 - 1

= 26

Answer:

D) C': ( -3, -2), D': ( -4, 1), E': ( -1, -2)

Step-by-step explanation:

Formula for this equation:

(x - 5, y - 3)

C:

(2, 1)

(x - 5, y - 3)

C': ( -3, -2)

E:

(4, 1)

(x - 5, y - 3)

E': ( -1, -2)

D:

(1, 4)

(x - 5, y - 3)

D': ( -4, 1)

Answer:

468

Step-by-step explanation:

Employee : instructor = 24 : 2

If there are 39 instructors

Employee = x

Employee : instructor = x : 39

Equate both ratios

24 : 2 = x : 39

24/2 = x/39

Cross product

24 * 39 = 2 * x

936 = 2x

x = 936/2

x = 468

Employees = x = 468

Answer:

4y−12

Step-by-step explanation:

4(y−3)

Use the distributive property to multiply 4 by y−3.

4y−12

Answer:

The figure should be 56 units squared.

Step-by-step explanation:

The long side is 14 units long (6+6+2) and the short side is 4 units long, so 14 multiplied by 4 is 56.

Answer:

Step-by-step explanation:

It would be the middle of the 6 and 5 because you go -4 plus to to the left and in half would be in the middle of that.

Answer:

x=11

mMN=65

mNP=115

mNQP=245

Step-by-step explanation:

10x-45=6x-1

4x=44

x=11

mMN 6(11)-1=65/ 10(11)-45=65

mNP 180-65=115

mNQP 65+115+65=245

Answer:

The anwser is that it's 8 inches

Step-by-step explanation:

How i figured this out is since it's a woksheet,

I can guess that its a rectangle or quadrtilateral. One side is 6 inches, so the exact opposite side is also the same size, so we would have to double the 6 to 12. We know that the perimeter is 28, we can subtract 28 from 12 so that we can find out how long it is. We get 16 from 28-12 and we need to half the amount to find out how long one side is. let me know if you have any more quesitons because i dont know if i explained it well

Answer:

36

Step-by-step explanation:

The formula of LCM is LCM(a,b) = ( a × b) / GCF (a,b)

The Greatest Common Factor of (9,12) = 3

Therefore

LCM of 9 and 12 = (9 × 12) / 3

= 108/3 = 36

LCM of 9 and 12 = 36

Irrespective of the method, the solution to our question LCM of 9 and 12 is the same.

Therefore, LCM of 9 and 12 is 36

Answer:

x = 4

Step-by-step explanation:

Given a line parallel to a side of the triangle and intersecting the other 2 sides then it divides those sides proportionally, that is

[tex]\frac{10-x}{x}[/tex] = [tex]\frac{3}{2}[/tex] ( cross- multiply )

3x = 2(10 - x)

3x = 20 - 2x ( add 2x to both sides )

5x = 20 ( divide both sides by 5 )

x = 4

Answer:

3·4·5 is greater than -3·-4·-5

Step-by-step explanation:

3·4·5 = 60

-3·-4·-5 = -60

Answer:

[tex] m\angle PRQ =49\degree [/tex]

Step-by-step explanation:

[tex] m\angle PSQ = 360\degree - (128\degree + 134\degree )[/tex]

[tex] m\angle PSQ = 360\degree - 262\degree [/tex]

[tex] m\angle PSQ = 98\degree [/tex]

Now, by inscribed angle theorem:

[tex] m\angle PRQ = \frac{1}{2} \times m\angle PSQ [/tex]

[tex] m\angle PRQ = \frac{1}{2} \times 98\degree [/tex]

[tex] m\angle PRQ =49\degree [/tex]

Answer:

504

Step-by-step explanation:

TSA (total surface area) = 1/2(p)(l) + B

p (perimeter) = 4(14) = 56

l (slant length) = 11

B (area of vase) = 14(14) = 196

TSA = 1/2 (56) (11) + 196

= 28(11) + 196

= 308 + 196

= 504

Answer:

28 years

Step-by-step explanation:

The difference between 30,000 and 4,800 is 25200. So we divide this number by 900 to find out how many years it will take for the truck to depreciate to this value
