evaluate the series 2 + 4 + 8 + 16 + 32 + 64

Answer:

The answer is -3/5 > -2/3

Step-by-step explanation:

okay

Answer:

the answer is. ......

−3/5>2/3

The three inside angles need to equal 170 when added together.

When two sides are the same which is shown by the little lines through the sides the two bottom angles are the same.

1. X = 170-80-80 = 20

2. X = 180-75-75 = 30

3. X = 180-70 = 110/2 = 55

Step-by-step explanation:

1) x+80°+80°=180°

x=180°-160°

x=20°.

2) as it is a isosceles triangle, y =75°.

x+75°+75°=180°

x=180°-150°

x=30°.

3) 2x+70°=180°

2x=110°

x=55°.

hope all these helps you.

Answer:

16 problems

Step-by-step explanation:

1. First, we must know that to find how many problems the student solved, we have to multiply the percentage he got by the total number of problems.

2. (Solving)

Therefore, the student answered 16 problems correctly.

Answer:

16

Step-by-step explanation:

Answer:

[tex]12 \div \frac{3}{4} = 12 \times \frac{4}{3} = 12 \times 4 \div 3 = 4 \times 4 = 16 \\ 16 \times 5 = 80 \: ft \: [/tex]

first you must know how many 3/4 do you have

because of scale

and after that multiply to 5 to get actual length

Answer:

A): f(x) = (x – 1)² + 2

Step-by-step explanation:

The quadratic function, f(x) = (x – 1)² + 2 is in vertex form: y = a(x - h)² + k, where:

The function, f(x) = (x – 1)² + 2, provides the pertinent information that allows us to determine the parabola's minimum value, as the value of a is a positive, which implies that the parabola is upward facing, and the vertex, (1, 2) is the minimum point.

Answer:

Look where the function intersects the x axis. The x coordinate of those points are the zeroes of the function

Step-by-step explanation:

P = 2((10 + x) + x)

The perimeter of a rectangle is the sum of the length and width multiplied by 2

P = 2(l + w)

[to simplify the expression]

P = 2 × (l + w)

[using x to represent the width]

w = x

l = x + 10

P = 2 × ((10 + x) + x)

P = 2((10 + x) + x)

Answer:

20) 7/16 = 0.4375

21) 1/6 = 1.6 repeating

22) 2 4/5 = 2.8

23) 98 2/3 = 98.6 repeating

24) 0.8 = 4/5

25) 26 1/5

26) 72.1 repeating = 72 1/9

27) 0.505 = 101/200

Explanation:

To convert fraction into decimal, divide the numerator by the denominator and that's your answer. For example:

7 ÷ 16 = 0.4375.

To convert a decimal into a fraction, place the number after the decimal point over the number place it's in. For example: If you look at 0.8 , 8 is in the tenths place, so you place it over 10 like this 8/10, and then you simplify. Half of 8 is 4 , and half of 10 is 5, so you'd have 4/5.

For #27, since 505 in 0.505 , is in the thousandths place, you'd put it over 1,000 like this 505/1000 and then you simplify. Look at image above to learn how to simplify 505/1000.⤴⤴⤴

Pretty easy if you use a calculator

Answer:

b = 12

Step-by-step explanation:

7b = 84

We can break down 7b as 7 x b

7 x b = 84

We divide both sides by 7:

7 x b ÷ 7 = 84 ÷ 7

b = 12

Answer:

y = 6x + 3

Step-by-step explanation:

6x - y = 1

6x -1 = y

Slope = 6

Point (-1,-3)

y-intercept = -3 - (6)(-1)

= -3 + 6 = 3

y = 6x + 3

Answer:

  h = (1 -2u² ± √(1 -4u²-12u⁴))/g

Step-by-step explanation:

This is a quadratic in h, so there are two solutions.

Written in standard form, the given equation is ...

  (-g/2)h² +(1-2u²)h -8u⁴/g = 0

The quadratic formula tells you the solution for h is ...

  h = (-(1 -2u²) ±√((1 -2u²) -4(-g/2)(-8u⁴/g)))/(2(-g/2))

  h = (2u² -1 ± √(4u⁴ -4u² +1 -16u⁴))/-g . . . . . simplify

  h = (1 -2u² ± √(1 -4u²-12u⁴))/g . . . . . . . . collect terms

Answer:

1. is 283.9953

Step-by-step explanation:

360 degrees - 76.0047 degrees is 283.9953

Step-by-step explanation:

given,

points = (7,0) & (3,6)

we know,

slope = y_2 - y_1 / x_2 - x_1

now,

→ 6 - 0/3-7

→ 6/-4

→ -1.5 or 3/-2

therefore , slope of line is -1.5 OR In the form of fraction it is 3/-2.

hope this answer helps you dear...take care and may u have a great day ahead!

Step-by-step explanation:

Answer:

50 (mph)    = rate of passenger train

Step-by-step explanation:

Let the rate of  the freight train  =   R

Let the rate of the  passenger train  be R +  30

The freight train  has  been  traveling for 2 + 3   =  5 hours

And the passenger train has  been traveling for  3 hours

And they  have traveled the same distance   when  the passenger  train  overtakes the freight train

So    using rate * time  = distance we have that

R(5)  = (R + 20) 3      simplify

5R  =  3R  +  60     subtract 3R from  both sides

2R  = 60           divide  both sides  by  2

R = 30   (mph)  = rate of freight train

R +  20  =  50 (mph)    = rate of passenger train
