Answer:
Niamh gets 12 and Jack gets 24.
Step-by-step explanation:
4:8 is equal to 1:2. 1 part + 2 parts is equal to 3 parts, which is equal to the whole. 36 is the whole, so 36/3 is equal to 12. 1 * 12 is equal to 12, and 2 * 12 is equal to 24.
It is 1.5 times because $63 divided by $42 is $1.5.
I hope this is what you meant.
Answer:
a. Check the diagram
b. He walked 58 feet
c. He is 18 feet far away from the house
Step-by-step explanation:
a. Eli started inside the house an walked 12 feet (blue arrow), after that he keep walking until the mailbox for 32 feet (green arrow) and after that he came back until the dog 14 feet (red arrow).
b. For calculating how far has he walked we need to take into acount all the travel so we add all the arrows:
12ft + 32ft + 14ft =58ft
He walked 58 feet.
c. The distance from the dog to the house is determine by the substraction between the distance to the mailbox with the distance he walked to the dog then:
32ft - 14ft = 18ft.
He is 18 feet far away from the house.
Answer:
y=x+6
Step-by-step explanation:
the co-ordinate points are (-2,4)and (4,10) so <u>y2-y1 </u>
x2-x1
<u>10-4 </u> =6
4-2 =6 which will be 1 as the gradient so you will form an equation
<u>y-10</u> =1 cross multiply the values with one so the answer will be y-10=x-4
x-4
take -10 to the other side it will be y=x-4+10 hence y= x+6
