Answer:4.03 x 10^4

Step-by-step explanation:

Answer:

w = -12

Step-by-step explanation:

-1/4w - 8 + 8 = 3

-1/4w = 3

w = 3 / -1/4

w = 3*4/-1

w = 12/-1

w = -12

From what I understand, we need to find x, y, and z.

We can easily find x by knowing a triangle has 180°.

Add 72+86=158 and then subtract 180-158 which gets you 22.

Now we have x=22°.

To find y, we first must find z. We can find z using the vertical angles theorem. This means x and z and the same, so z=22°.

Now, we can now find y by adding 70 and 22 = 92.

Subtract 180-92=88°.

All values have been found!

x=22°

y=88°

z=22°

Answer:

97.27 kg

Step-by-step explanation:

1kg = 2.2 lb

214 lb = ?kg

Make it into an equation:

1 kg/ 2.2 lb = ?kg / 214 lb

? = 1kg x 214lb ÷ 2.2 lb

?= 214lb ÷ 2.2 lb

? ≈ 97.27 kg / 214 pounds

Verify :

97.27 x 2.2 ÷ 214 ≈ 0.99 ≈ 1 kg

Answer:

D

Step-by-step explanation:

they both equal each other. 5x+7=9x-63

then you would take 70 divided by 4

which equals 17.5

Answer:

A

Step-by-step explanation:

5x + 7 + 9x -63 = 180

     14x - 56 = 180

            + 56    +56

             14x = 236

 divide both sides by 14

           x = 16.85

Answer: 61.51%

Step-by-step explanation:

To find : percentage for a 20 year old man with a cholesterol level less than 190.

20 lies between 18 and 24.

For this , Cholesterol levels are normally distributed with a mean([tex]\mu[/tex]) of 178 and a standard deviation([tex]\sigma[/tex]) of 41.

let X = cholesterol level in 20 year old man.

Required probability = [tex]P(X< 190)=P(\dfrac{X-\mu}{\sigma}<\dfrac{190-178}{41})[/tex]

[tex]=P(z<0.2926)\ \ \ \ [z=\dfrac{X-\mu}{\sigma}]\\= 0.6151 [\text{By p-value table}][/tex]

hence, the percentage for a 20 year old man with a cholesterol level less than 190 = 61.51%

Answer:

Angle DHG

Step-by-step explanation:

Answer:

x = 20

y = 25

Step-by-step explanation:

Vertical angles are always congruent, that is a theorem.

Set the vertical pairs equal to each other.

182 - 4x = 5x + 2

The lowest of the two coefficients is 4x, so that will be added to both sides.

4x + 5x = 9x

Simplify

9x + 2 = 182

Subtract both sides by 2

9x = 180

Divide by 9

180/9 = 20

x = 20

Plug in the 20 to get the angle measure.

182 - 80 = 102

the vertical pairs are 102 degrees

There is another theorem that sets the two angles outside as congruent.

So set 4y + 2 = 102

Subtract 2

100

Divide 4, which equals 25

y = 25

Answer:

1092

Step-by-step explanation:

first calculate expense for each week;

25+30+40= 95

expense after saving

25-7= 18

30-7=23

40-7=33

18+23+33= 74

total saving for each week= 95-74=21

(you can also just do 7*3=21 to know total saving each week)

weeks in a year=

365 days/7= 52.14 = 52 weeks

total savings for the year= 52*21=$1092

Answer:

Step-by-step explanation:

There are 3 variables

Saving amount is

Total saving per week is

Saving per year considering 52 weeks per average year is:

Answer: B

4 inches

Step-by-step explanation:

The weight travel from maximum displacement to minimum displacement is 4 inches.

The relative shift in a wave's position that occurs when it passes through a medium is referred to as wave displacement.

When a wave oscillates, displacement is the movement of a particle or field relative to its resting location. The amplitude of the wave is a measurement and recording of the largest displacement that has place.

Given:

From the graph we can a wave.

Now, we can see that the Wave is 2 inches in crust and 2 inches in trough.

So, the weight travel from maximum displacement to minimum displacement is

= 2 + 2

= 4 inches.
