So answer:
</span>m∠C=m∠F
Answer:
Option A (k < -1).
Step-by-step explanation:
Enlargement is one of the linear transformations which changes the size of the shape formed by a combination of some points in the exact proportion. For enlargement (also called dilation), there are two parameters required: the center of enlargement, according to which the transformation occurs, and the scale factor, the size by which the transformation is done. The scale factor can be of any number k. If k is larger than 1 or -1, then it will cause enlargement. If k is between -1 and 1, it will cause anti-enlargement. The magnitude of k determines the size and the sign of k determines the direction. So in this case, k < -1 will cause the enlargement: even though the scale factor is less than -1, but it will enlarge the shape on the opposite direction. Option B and Option C cause anti-enlargement and Option D cause no enlargement or anti-enlargement. So Option A is the correct answer!!!
Answer:
multiply 7 by 42
= 294
42 x 7 can be done as mental math, but that is challenging for some people.
Answer:
26,910 meters
Step-by-step explanation:
The glacier moves 29.9 meters a day.
In 100 days it will move 29.9(100)=2990 meters.
In 1000 days it will move 29.9(1000)=29900 meters.
29,900-2,990=26,910 meters
Answer:
15% discount
Step-by-step explanation:
Given:- Prices for a day ticket entrance at Disneyland Paris resort are
adult=55
child=45
family(2 adults ,2 children)=170
To find:- The family discount in percentage
Solution:- According to the question, Prices for a day ticket entrance at Disneyland Paris resort are
adult=55
child=45
So the price for two adults is 2×55=110
and the price for two child is 45×2= 90
but for the family(2 adults ,2 children),the price is 170
So, though the number of members are same but here a family is getting (110+90-170)=30 rupees less than the actual price (200)
so the discount is 100×30/200 =15%
So the family will get 15% discount.
