With multiplication, there are a few handy rules to remember:
If you multiply an even and an even, the answer will be even!
If you multiply an odd and an odd, the answer will be odd!
If you multiply an even and an odd, the answer will be even!
Knowing this, if we go back and look at the numbers Evan is trying to multiply, we can try to use these rules!
The last number of that really big number is a 7, which is odd, and the number 2 is even, and because we know that an odd number times an even number is an even number, Evan will be right!
Answer:
To the nearest tenth of a degree
∠E= 47.9°
Step-by-step explanation:
ΔDEF , let's recognize that it's a right angle triangle because of the presence of ∠F=90°.
Other important measurements are
DE = 82 feet, and EF = 55 feet.
We are to find ∠E
Let's find the missing side first
Side DF
DF² = DE² - EF²
DF²= 82²_55²
DF²=6724-3025
DF²= 3699
DF= 60.82 feet
Let's use the sine formula to look for the angle.
DF/sin ∠E= DE/sin 90
Sin 90= 1
DE= 82
DF= 60.82
Sin ∠E= DF/DE
Sin ∠E= 60.82/82
Sin ∠E= 0.7417
∠E= sin^-1 (0.7417)
∠E= 47.8764
To the nearest tenth of a degree
= 47.9°
47,000/100 = 470
470 = 1%
470 x 14.4 = 6768
The price of the car will decrease by $6768.
47,000 - 6768 = 40,232.
The price of the next model will be $40,232.
The probability that she got exactly 3 questions correct is 0.208 , Option B is the correct answer.
<h3>What is Probability ?</h3>
Probability can be defined as the likeliness of
If you use the formula P(r)=
P is the probability of success = 3/4 = .25
the total number of questions is n = 8
the total number of questions that Johnni got correct is r = 3
the probability of getting an answer wrong is q = 1-0.25 = 0.75
Substituting all of these values
= .208.
The probability that she got exactly 3 questions correct is 0.208 , Option B is the correct answer.

Answer:
D)99 degrees
Step-by-step explanation:
The answer is D. All the angles in any quadrilateral add up to 360 degrees. And since the figure is a paralledlogram, for each angle there is another angle with the same measurement. So 81 + 81 + x + x = 360 which gives us 162 + 2x = 360. If you solve for x you get 99 degrees.
