What is the surface area of the solid?

Using the Pythagorean Theorem, it is found that the group will have to travel 90 miles.

The Pythagorean Theorem relates the length of the legs [tex]l_1[/tex] and [tex]l_2[/tex] of a right triangle with the length of the hypotenuse h, according to the following equation:

[tex]h^2 = l_1^2 + l_2^2[/tex]

In this problem:

[tex]d^2 = 25^2 + 60^2[/tex]

[tex]d = \sqrt{25^2 + 60^2}[/tex]

d = 65.

The total distance is given by:

Td = 25 + 65 = 90 miles.

Answer:

4 true false and 8 short answer

Or 15 true false and 5 short answer

Or 26 true false and 2 short answer

Step-by-step explanation:

let x be the number of true-false questions

   y be the number of short-answer questions

Then we have to solve the equation 3x + 11y = 100

Important: x and y are natural numbers

3x + 11y = 100 ⇔  100 - 11y = 3x

If y=10 ⇒ 100 - 11×10 = −10  = 3x impossible because x ≥ 0

If y=9 ⇒ 100 - 11×9 = 1  = 3x impossible because x is a natural number

If y=8 ⇒ 100 - 11×8 = 12  = 3x ⇒ x = 12/3 = 4

Then (x,y) = (4,8) is a solution to the equation

If y=7 ⇒ 100 - 11×7 = 23  = 3x impossible because x is a natural number

If y=6 ⇒ 100 - 11×6 = 34  = 3x impossible because x is a natural number

If y=5 ⇒ 100 - 11×5 = 45  = 3x ⇒ x = 45/3 = 15

Then (x,y) = (15,5) is a solution to the equation

If y=4 ⇒ 100 - 11×4 = 56  = 3x impossible because x is a natural number

If y=3 ⇒ 100 - 11×3 = 67  = 3x impossible because x is a natural number

If y=2 ⇒ 100 - 11×2 = 78  = 3x ⇒ x = 78/3 = 26

Then (x,y) = (26,2) is a solution to the equation

If y=1 ⇒ 100 - 11×1 = 89  = 3x impossible because x is a natural number

If y=0 ⇒ 100 - 11×0 = 100  = 3x impossible because x is a natural number

The probability that the company will have to pay at least $150,000 in benefits next year is 0.047 if the there are 120 women.

It is defined as the ratio of the number of favorable outcomes to the total number of outcomes, in other words the probability is the number that shows the happening of the event.

The probability of dying:

P(dying) = 1/150

P(living) = 1 - P(dying) = 1 - 1/150 = 140/150

There are 120 women.

P(x≥3) = 1 - [P(x=0) +P(x=1) + P(x=2)]

[tex]\rm P(x\geq 3)=1-[(120 \ choose \ 0)(1/150)^0)((149/150)^{120})+[/tex]  

                  [tex]\rm (120 \ choose \ 1) ((1/150)^1) ((149/150)^{119}) +[/tex]

                  [tex]\rm (120 \ choose \ 2)((1/150)^2)((149/150)^{118})][/tex]

P(x≥3) = 0.047

Thus, the probability that the company will have to pay at least $150,000 in benefits next year is 0.047 if the there are 120 women.

ANSWER IS D

Answer:

16

Step-by-step explanation:

The figure shown is a trapezoid

Area of a trapezoid = 1/2(bottom base length + top base length) × height

Bottom base length = 7 units

Top base length = 1 unit

Height = 4 units

So area = 1/2 ( 7 + 1 ) × 4

==> add 7 and 1

Area = 1/2 (8) × 4

==> multiply 1/2 and 8

Area = 4 × 4

==> multiply 4 and 4

Area = 16

Answer:

AB = 21

Step-by-step explanation:

the line EB is parallel to the side of the triangle DC and intersects the other 2 sides proportionally , that is

[tex]\frac{AE}{ED}[/tex] = [tex]\frac{AB}{BC}[/tex] ( substitute values )

[tex]\frac{14}{12}[/tex] = [tex]\frac{AB}{18}[/tex] ( cross- multiply )

12 AB = 14 × 18 = 252 ( divide both sides by 12 )

AB = 21

Since the tuba creates a 4th harmonic of frequency 116.5 hz, the length of pipe in tuba is 6.57 m

Since the tuba is an closed-pipe instrument, we need to find the frequency of a closed pipe

The frequency of a closed pipe f = nV/4L where

Making L subject of the formula, we have

L = nV/4f

Since the tuba creates the 4th harmonic with frequency 116.5 Hz.

Substituting the values of the variables into the equation, we have

L = nV/4f

L = 9 × 340 m/s/4 × 116.5 Hz

L = 3060 m/s ÷ 466 Hz

L = 6.57 m

So, the length of pipe in tuba is 6.57 m

Answer:

(x + 7)/(x + 1)

Step-by-step explanation:

Simplify the following:

(x^2 + 11 x + 28)/(x^2 + 5 x + 4)

The factors of 4 that sum to 5 are 4 and 1. So, x^2 + 5 x + 4 = (x + 4) (x + 1):

(x^2 + 11 x + 28)/((x + 1) (x + 4))

The factors of 28 that sum to 11 are 7 and 4. So, x^2 + 11 x + 28 = (x + 7) (x + 4):

((x + 4) (x + 7))/((x + 4) (x + 1))

((x + 7) (x + 4))/((x + 4) (x + 1)) = (x + 4)/(x + 4)×(x + 7)/(x + 1) = (x + 7)/(x + 1):

Answer: (x + 7)/(x + 1)

Next time write the expression how it needs to be, the way you wrote it woould have given a toally different result.

x^2 + 11 x + 28/x^2 + 5 x + 4

Answer:

solving this as you would in algebra 2:

x2+11x+28 / x2+5x+4 = x+7 / x+1

Step-by-step explanation:

solving this as you would in algebra 2:

x2+11x+28 / x2+5x+4

1. on both the top and the bottom you have to find a factor of the last number (in this case 28 and 4) that multiplys to be the number but adds to be the 2nd term (11x and 5x)

2. for the top the two terms would be (x+7) and (x+4). on thebottom half it would be (x+4) and (x+1)

** 7 times 4 equals 28, 7 plus 4 equals 11; 4 times 1 equals 4, 4 plus 1 equals

3. x+4 is common term on both the top side and the bottom half so you cross it out. this leaves us with our answer of: x+7 over x+1

cross multiply

800×42=33,600

then divide by 100

33,600/100=336

Answer:

336

Step-by-step explanation:

If 42% said they shopped online last week, that means the number of people who said they shopped online last week is 42% of 800. "Of" just means we should multiply, and since 42% = 42/100 (since % is just /100), we can use the following to find the answer (I used cross multiplication to simplify):

42          800         42         8
