Answer:

this should be it

Step-by-step explanation:

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:

Step-by-step explanation:

ruff

123 dogs adoption in january

196 dogs adoption in July

Total adoption for the year = 123 + 196

= 319 adoptions

barks

78 dogs adoption in January

135 adoption in July

Total s like adoption for the year = 78 + 135

= 213 adoptions

Difference in the number of dogs adoption at each shelter that year

= Ruff total adoption for the year - Bark's total adoption for the year

= 319 adoptions - 213 adoptions

= 106

The difference in the number of dogs adoption at each shelter that year is 106

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:

10 feet per sec

Answer:

B = 3

Step-by-step explanation:

The answer has to be 3 because this is a 3-4-5 triangle. We can also you the Pythagorean theorem to solve for B.

a²+b²=c²

(4)²+b²=(5)²

16+b²=25

b²=9

√b=√9

b=3

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

the pattern is

multiplied by -5

so...

1500 *-5 = -7500

-7500*-5 = 37500

hope this helps

Answer:

-7500,37500 are next two numbers in the pattern

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:

Answer: 2.852 × 10-1

Step-by-step explanation:

7.13 x 10^-3 =  0.00713

0.00713 x 40 = 0.2852

0.2852 = 2.852 × 10-1

Answer:

Answer: 2.852 × 10-1

Step-by-step explanation:

7.13 x 10^-3 =  0.00713

0.00713 x 40 = 0.2852

0.2852 = 2.852 × 10-1

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%
