Need help on this ASAPPPPPPPP
AURORKA [14]

Answer:

B

Step-by-step explanation:

We know that the blue triangle is the image as it has the ' on the letters. For example G'.

To first start off, you can look at any points to help solve this problem. I used the point H to help me solve this

Since we know that the black triangle is our old image we know the distance in x values between the black triangle to the blue is -2 as it moves to the left 2 times. (Note: it's going more into the negatives, if it were going to the right it would be positive)

Now we do the same to find our y values, and we see that y value for h on the black triangle goes up +1.

Now we know that the X goes to the left two times to get -2 and that the Y goes up once to get +1.

Hope this helps! :)

Joy makes 6.5 litres of soup correct to the nearest 0.5 litre. She serves the soup in 280 ml portions, correct to the nearest 10
miss Akunina [59]

Answer:

Joy definitely does have enough soup for 22 people.


Step-by-step explanation:

Upper Bound: 285ml  turn it to 0.285 L                      10÷2=5

280ml

Lower Bound: 275ml turn it  to 0.275 L

Upper Bound: 6.75 L                           0.5÷2=0.25

6.5 Litters

Lower Bound:6.25  L

6.75÷0.275=24.54 or 25  

6.25÷0.285=21.92 or 22

22≤x<25 Joy definitely does have enough soup for 22 people.
