Yes Jackie would have enough money to buy a CD player. So you would have to do 32.95 times that by 30% (.3) and would get 9.885 which you would round that to 9.89 dollars.
Hello,
*I will move straight to the math. If you have questions, ask away! :)
* All calculations are in “degree mode” for a TI calculator or other calculator.
I will apply Laws of Sines/Cosines and inverse functions for your math.
Answer:
D.) AB≅A′B′, ∠A≅∠A′, and ∠C≅∠C′
Step-by-step explanation:
<u>Option A</u> identifies two sides and the angle not between them. The two triangles will be congruent in that case <em>only if the angle is opposite the longest side</em>, which is <u>not true</u> in general.
<u>Option B</u>: same deal as Option A.
<u>Option C</u> identifies three congruent angles, which will prove the triangles <em>similar, but not necessarily congruent</em>.
<u>Option D</u> identifies two angles (sufficient for similarity) and one side, sufficient (with similarity) for congruence. The applicable congruence theorem is AAS.
Answer:
49
Step-by-step explanation:
The area of a shape is the amount of space it can occupy.Laura's design will be light enoughThe shape is given as a trapezium (see attachment).First, calculate the height (h) of the trapezium using the following Pythagoras theorem 52=h2+x2 Where: x=11−92=1 So, we have: 52=h2+x2 52=h2+1225=h2+1 Collect like terms h2=25−1 h2=24 Take square root sh=4.90The area of the shape is then calculated as follows: Area=12(11+9)×h Area=12(11+9)x4.90 Area=12×20×4.90 Area=10×4.90 Area=49
The area of the shape is 49 square inches.Hence, the shape will be light enough (because 49 is less than 80
