Square root (8-0)^2 + (8+7)^2
square root 64+15^2
=8+15
= 23
Ratio of dog bark is 4:5
Multiply that by 20 each side
Ratio is now 80:100
So 80%
If they walk past 45 time you just have to multiply the ratio 4:5 by 9
36:45
So the dog would bark 36 times
Hello!
1 foot = 12 inches
12 × 6 = 72
_____________________________
ANSWER:
Since there are 72 inches in 6 feet, 6 feet are greater than 7 inches.
Answer:

Step-by-step explanation:
A triangle adds up to 180.
180 - 50 = 130
Since both of the missing angles are congruent each of the missing angles is 65 degrees.
130/2 = 65
As per the exterior angle theorem, the measure of the exterior angle is determined by the sum of the opposite interior angles.
65 + 65 = 130
So, the measure of 
Answer:
31 pennies
Step-by-step explanation:
Given that:
Breaking the number of pennies into 2 groups, there is 1 penny left over.
Breaking the pennies into 3 groups, there is 1 penny left over.
Breaking the pennies into 5 groups, there is 1 penny left over.
Breaking the pennies into groups implies that the same number of pennies are in each group for each case. Since there is no restriction to the number of pennies in the groups for all cases, then the total number of pennies would be 31.
So that;
31 = 15 + 15 + 1 = 2 groups + 1
31 = 10 + 10 + 10 + 1 = 3 groups + 1
31 = 6 + 6 + 6 + 6 + 6 + 1 = 5 groups + 1
There are 31 pennies.
