Two shelters offers dog adoption twice a year ruff had 123 dogs adoption in january 196 fogs adoption in July barks had 78 dogs adoption in January and 135 adoption in July estimates the difference in the number of dogs adoption at each shelter that year
Answer:
106
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

Find x and y
Helpppp please
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

In the process of making a financial forecast, Farid has been looking closely at his
variable expenses. Currently, each week he spends an average of $25 on food, $30 on
entertainment, and $40 on clothing and other purchases. If Farid reduced his variable
expenses in each of these three categories by $7 a week, how much would he save
over the course of one year?
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:
$1092Step-by-step explanation:
There are 3 variables
Food, entertainment and clothing and other purchasesSaving amount is
$7 per each variable per weekTotal saving per week is
$7*3 = $21Saving per year considering 52 weeks per average year is:
$21*52 = $1092answer this please please
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

Cholesterol levels in men 18 to 24 years of age are normally distributed with a mean of 178 and a standard deviation of 41. The cholesterol levels in women 18 to 24 years of age has a mean of 167 with a standard deviation of 38. What is the percentage for a 20 year old man with a cholesterol level less than 190?
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%
Find the value of this triangle!
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°
Convert 214 pounds to kilograms. Use 1 kg = 2.2 lb.
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
