1: supplementary means 180 degrees so subtract 30 from 180 and angle b is 150 degrees.
2: complementary means 90 degrees so subtract 49 from 90 and the second angle is 41 degrees.
3: a right angle is 90 degrees.
4: congruent means same size same shape so if the first angle is 40 degrees then the second angle would also be 40 degrees.

.At a certain animal shelter, the ratio of puppies to adult dogs is 7 to 4. This week there are a total of55 dogs in the shelter
Advocard [28]

Answer:

There are 35 adult dogs and 20 puppies

<em></em>

Step-by-step explanation:

<em>Represent the puppies with P and the Adult dogs with A</em>

Given

A : P = 7 : 4

Dogs = 55

Required

Determine A and P

First, we need to sum the ratios;

Total = A + P

Total = 7 + 4

Total = 11

Adult Dogs is then calculated as follows;

A = \frac{A\ Ratio}{Total} * Dogs

A = \frac{7}{11} * 55

A = \frac{385}{11}

A = 35

Puppies is calculated by subtracting the number of adult dogs from the total

P = Dogs - Adult\ Dogs

P = 55 - 35

P = 20

<em>Hence;</em>

<em>There are 35 adult dogs and 20 puppies</em>

The sum of 2 consecutive integers is 21 what’s the two numbers
aleksklad [387]

Answer:

10 and 11

Step-by-step explanation:

Let the first integer be x.

Then the next one, since it's consecutive, must be (x+1).

The two equals 21. Thus:

(x)+(x+1)=21

Combine like terms:

2x+1=21

Subtract 1 from both sides:

2x=20

Divide both sides by 2:

x=10

So, the first integer is 10.

And the second integer is 10+1=11.
