Answer:
The equation that Deon can use to find the time 't' it takes for his ride is t=distance/rate or t=15/20 or 0.75 hours.
Step-by-step explanation:
The relationship between distance, rate and time is a common formula represented by d=rt where 'd'=distance, 'r'=rate and 't'=time. Distance is typically calculated in miles, where rate is given in miles/hour and time is the hours. In this case, because we are looking for 't', we would simply plug in the values of distance and rate to get 20=15t. In order to solve for 't', we need to use inverse (opposite) operations, dividing both sides by 15 and getting 0.75 hours for 't'.
P= a+b+c = 76
side a = 2b = 30
side b = b = 15
side c = 2b + 1 = 31
Answer:

Step-by-step explanation:
we know that
A gross is equal to 120 ones or ten dozen
what is 15 tens - 1 gross
we know that
15 tens means ----> That you are adding 10, 15 times or multiplying 10 by 15, which gives you
1 gross means ---> That you are adding 10, 12 times or multiplying 10 by 12
which gives you
so
The algebraic expression of 15 tens - 1 gross is equal to
Convert to word expression
3 tens
Answer:
12a^9b^7
Step-by-step explanation:
Multiplying variables of the same base, will require you to add the exponents.
4a^3b^2 * 3a^6b^5
4*3 = 12
a^3 * a^6 = a^9
b^2 * b^5 = b^7
12a^9b^7
Answer:
Quadrant IV
Step-by-step explanation:
Quadrant I = (+ , +)
Quadrant II = (- , +)
Quadrant III = (- , -)
Quadrant IV = (+ , -)
(1/2 , -1.8)
1/2 is +
1.8 is -
(+ , -)
It lies on Quadrant IV
