Start with 21 cups , substract 5.5 (5 and one half) , 2.25( 2 and one fourth), and then divide by two (divided into 2 equal portions) and the result is 6.625 and if you divide the options as an improper fraction, you'll get 6 and five eights... so your answer is D.
Answer:
F or B
Step-by-step explanation:
Answer:
18°
Step-by-step explanation:
1. ∠A and ∠B are complementary angles, so they add up to 90°.
- This means that 2x - 4 + 5x + 17 = 90
2. To find the measure of ∠A, we first have to solve for x.
3. (Solving)
Step 1: Simplify both sides of the equation.
Step 2: Subtract 13 from both sides.
Step 3: Divide both sides by 7.
4. Now that we know x = 11, let's plug that value into (2x - 4) to find the measure of Angle A.
Therefore, the measure of ∠A = 18°.
Answer:
Reflection, rotation and translation
Step-by-step explanation:
By definition, a rigid transformation is a transformation that preserves length.
Dilation and stretch change the measure of the figure, and then, they are not rigid transformations.
On the other hand, reflection, rotation and translation don't change the measure of the figure, only change its position and orientation, so, they are rigid transformations.
