Answer:
2
Step-by-step explanation:
Given Data:
total distance= 850 miles
gas tank holds gas= 15 gallons
mileage = 72/3.2 miles/gallon
if
72 miles uses= 3.2 gallon
then
850 miles uses= x gallons
by cross-multiplication we get
72x=3.2(850)
x=37.778
i.e. 850 miles will use 37.7778 gallon of gas
Asgas tank holds 15 gallons
number of times gas tank is used up= 37.3/15
= 2.518
rounding off
number of times gas tank is used up=3
As they filled the gas tank at the start of the road trip, hence 3-1=2
ADDITIONAL STOPS FOR GAS WILL THEY NEED TO MAKE TO GET TO THEIR DESTINATION =2 !
Answer:
D. either x or y must equal 0
Step-by-step explanation:
Its given that xy = 0
Remember that product of two numbers can be zero only if:
Both of them are zero or Either of them is zero as zero multiplied to any non-zero number will always be equal to zero. This is known as Zero Product Property.
So, if the product of x and y is equal to 0 there are two possibilities:
- Both x and y are equal to 0
- Either x or y must be equal to 0
Note that the condition both x and y are equal to zero is not a must condition, because even if one of them is equal to zero, the entire expression will be equal to zero.
Hence, the condition which has to be true in all cases for xy = 0 is:
D. either x or y must equal 0
Answer:
8.06 is the correct answer
Answers:
B = 50
a = 10.9
c = 17.0
================================================
Explanation:
This is a right triangle, so the acute angles are complementary, meaning they add to 90
B+40 = 90
B+40-40 = 90-40
B = 50
Also, because this is a right triangle, we can use trig ratios to compute the missing sides
tan(angle) = opposite/adjacent
tan(40) = a/13
a = 13*tan(40)
a = 10.908
a = 10.9
cos(angle) = adjacent/hypotenuse
cos(40) = 13/c
c*cos(40) = 13
c = 13/cos(40)
c = 17.0
note: make sure your calculator is in degree mode
