She rounds it to $155, because it is the closest whole number.
Answer:
The length of BC is √105 cm or 10.2 cm.
Step-by-step explanation:
You have to apply Pythagoras Theorem, c² = a² + b² where c represents hypotenuse, a and b are the sides :
Answer:
3) 4x=15
6)b=$2.5
1) n= -12
Step-by-step explanation:
3. Given the equation ,
#Expand by removing the brackets:
#We then group the like terms to solve for x:
2+4x=17
4x=15
Hence, the equations equivalent is 4x=15
6. Let b be the cost of each bag of snack.
-Given that there are 4 friends who spent a total of $34 and each ticket costed $6.
-We equate the costs to the total to solve for b:
Hence, the cost of each bag of snack is $2.5
1) Given the equation
#First. we multiply each term by 3 to remove the fraction:
#We then group like terms together to solve for n:
#Divide all terms by -2 to get the value of n:
Hence n= -12
Answer:
11:16
Step-by-step explanation:
The ratio is 220:320.
Cancel the 0s then divide by 2.
22/2=11
32/2=16
Answer: 3/10 bucket will fill the barrel completely
Step-by-step explanation: If 1/5 of the bucket is 2/3 then we want to find 1/3 of 1/5 and multiply it by 3 to find the whole of the barrell 3/3 so 1/5 divided by 2 is 1/10 and multiplied by 3 is 3/10. In math form its 1/5=.2 so .2 divided by 2 is .1 and multiplied by 3 is .3 which also equals 3/10
