3 x 2 is 6. 6 x 5 is 30.. There you go, the answer is 30.
The triangles are similar because all pairs of corresponding angles are congruent.

Answer:
y = x / 7
Step-by-step explanation:
For us to get direct variation equation, we must introduce a constant term.
If y varies directly as x:
y ~ x
y = Kx
Where K, is the introduced constant.
Now let's solve to get a direct variation equation.
When y=3 , x=21
We substitute, y=3 and x=21 in the
y = Kx
3 = K 21
Divide both sides by 21
3 / 21 = K 21/ 21
K = 3/21
K = 1 / 7
Therefore, we introduce K = 1 / 7 into the mother equation.
y = 1/7 * x
y = x / 7
The direct variation equation for the situation:
y = x / 7
36 ft
Step-by-step explanation:
Since there is a right angle been formed, you will minus 90 from 40 = 50. Then you will add it to 46 = 96.
Since there is another right angle been formed you will also subtract 90 from 30 = 60.
Then to find the distance from the cat to the fireman you will subtract 96 from 60 =36.
Therefore your answer is 36 ft
Answer;
The cost is $0.07 per square inch
Step-by-step explanation:
In this question, we are asked to calculate the cost of the Chicago pizza per square inch rounded to the nearest cent.
Firstly, we will need to calculate the area occupied by the 14 inch medium pepperoni pizza made by Chicago pizza
Since the pizza is circular in shape, we use the formula for the area of a circle to calculate its area in square inch
Mathematically, the area of a circle is equal to π . Here, our r is half the size of the pizza as the 14 inch represents the full length of the pizza across the center of the pizza ( This is the diameter) d=2r or r = D/2 = 14/2= 7 inch
The area is thus = 22/7 × 7 × 7 = 154 square inch
Now, since the full pizza costs $10.49, the cost of the pizza per square inch is 10.49/154 = 0.068 = $0.07 per square inch
