Number six is 8 and what is the question for #7
(79 + 94 + 91 + 92 + x) / 5 > = 90 (thats greater then or equal)
(356 + x) / 5 > = 90....multiply both sides by 5, eliminating the 5 on the left
356 + x > = 90 * 5
356 + x > = 450
x > = 450 - 356
x > = 94......lowest score she can earn is 94
Answer:
-3
Explanation:
= -3
So first make the improper fraction into a mixed number by taking out all the whole numbers from the numerator (3) and making sure the proper sign is in front of the answer (- 3) your remainder is the original numerator minus the product of the answer times the denominator: 24 - (3 • 7) = 24 - 21 = 3. Rewrite the mixed number.
They reject if the pie is more than 3.2oz from 28oz.
The scale shows positive number if its more than 28oz.
The scale shows negative number if its less than 28oz.
The scale shows zero if its 28oz.
A . Scale reads -2.8oz which means less than 28oz, So accepted.
B. Scale reads 3.5oz which means 3.5oz more than 28oz. So rejected.
C. Scale reads -3.3oz which means less than 28oz, So accepted.
D. Scale reads 28oz which means more than 28oz, So rejected.
Answer:
- a rotation, followed by a translation
- a translation, followed by two reflections
Step-by-step explanation:
The rigid motions are the transformations that produce congruent images.
There are three main kinds of rigid motions :
- Reflections : Flips a figure across a line of reflection.
- Rotations : Rotates a figure about some degrees around a center point.
- Translations : Moves figure on a plane about some distance in a certain direction.
But dilation is not a rigid transformation because it may change the size of the image. It is usually used to shrink or enlarge a shape.
So, the options having dilation and term "stretch" cannot produce congruent figures.
Hence, the correct options are :
- a rotation, followed by a translation
- a translation, followed by two reflections
