B. The points do not show a proportional relationship because the difference between the y-coordinates is not the same.
C. The first two points show a proportional relationship with each other because the hourly rate of pay is $12 per hour

The ratio of dogs to cats being treated at a veterinarian's office this week is 5 : 2. Suppose there are 168 dogs and cats sched
Alexeev081 [22]

Answer:

48 cats

Step-by-step explanation:

Am interesting factoid about ratios:

The ratio a:b can be separated into fractional parts of \frac{a}{a + b} and \frac{b}{a + b}. We need to know the cat part. \frac{2}{5 + 2} = \frac{2}{7}, so that is the fraction part. Then, we multiply this fraction by 168 to get the total number of cats. This number is 48.

A) Rate (R)<br>24/5<br>Time = 1 month<br>Interest = Rs. 39.96​
yKpoI14uk [10]

Answer:  P = $ 1,998.01

Step-by-step explanation:

First, converting R percent to r a decimal

r = R/100 = 24%/100 = 0.24 per year,

putting time into years for simplicity,

1 months ÷ 12 months/year = 0.083333 years,

then, solving our equation

P = 39.96 / ( 0.24 × 0.083333 ) = 1998.007992032

P = $ 1,998.01

The principal required to

accumulate interest of $ 39.96

on a rate of 24% per year for 0.083333 years (1 months) is $ 1,998.01.

Pls help i really really need help on this. We just learned this but i can't remember it.
bulgar [2K]

Answer:

114 cm²

Step-by-step explanation:

Area of shaded region

= area of circle -area of square

\boxed{area \: of \: circle = \pi {r}^{2} }

Given that radius= 10cm, r= 10cm.

\boxed{area \: of \: square = side \:  \times side}

Let the length of a side of the square be x cm.

Applying Pythagoras Theorem,

10² +10²= x²

100 +100= x²

x²= 200

x =   \sqrt{200}

Area of square

= x²

= 200cm²

Area of shaded region

= 3.14(10²) -200

= 3.14(100) -200

= 314 -200

= 114 cm²
