First, you have to split 56 in half (because Lena bought 4 more than half of 56) 56 divided by 2 equals 28. Then you add 4 because again, Lena bought 4 more than half. That ends up at 32.
To find Jodie's bottles, you have to do 56 - 32, because the remainder of the bottles belongs to Jodie. I got 22.
Jodie bought 22 bottles of nail polish.
Answer:
B. -4
Step-by-step explanation:
When dilation is not about the origin then in order to find the scalar factor, we need to find the ratio of the corresponding lengths.
2 Vertices of smaller triangle (Pre-image):
Length of side:
Since distance is always positive so its 2 units.
2 Vertices of bigger triangle(Image):
Length of side:
Since distance is always positive so its 8 units.
For the given figure we see that the dilated image is rotated 180° from the original position. Thus, for such dilation the scalar factor is taken negative.
Thus the scalar factor can be calculated as:
Scalar factor = 
Scalar factor =-4
Answer:
$4
Step-by-step explanation:
I tried to make it as simple as possible.
8*5=40
4*10=40
so the least number of hot dogs you can buy so that you can also buy a matching number of buns is 40.
Answer:7
Step-by-step explanation:
This question is on the ukmt junior maths challenge which I'm doing now, out of the options given I got 7, because 2+4+6+5+(5×20)+(7×7)= 166, (then dividing that by the number of numbers to get the mean) so 166÷31= 5.354.....
Also the 3 has a recurring symbol above it
The 7 is times seven so uh yeah<3
