Area of Triangle= ( h*w ) /2.
So, 12 times 5 is 60. But then, you need to divide by 2 to get 30 sq. inches. Hope this helped!
Answer:
9*sqrt(2) (third in your list of answer)
Step-by-step explanation:
Lets indicate the vertices with the letters beginning the upper vertice A next clockwise B and finally C (right angle)
Angle C=45 degrees. ANgle C is 90 degrees ( small square on the diagram means 90 degrees) So the angle A= 180-90-45=45 degrees.
Angle A=angle C=45 degrees=> AC=CB=9
Using Phitagor theorem will get AB= sqrt(AC^2+BC^2)=sqrt(81+81)=9*sqrt(2)
49x3= 147 so 10 reduction will make tim spend 137. 49x5= 245 so 20 reduction will make Craig spend 225. 225-147= 78 so Craig spends 78£ more than tim. All the offers state “X or Y” meaning it’s one or the other hence the ‘or’. Atleast that’s my interpretation of it.
Answer:
#4.
- 3 < - 2 1/2
If you consider the number line, the numbers increase from left to right. The number on the left is smaller than a number on the right.
- 3 is smaller than -2 1/2, it means -3 is on the left from the -2 1/2 on the number line.
#5.
Jada's score is positive, it means the number reflecting the score is to the right from zero on the number line.
Isabel's score is negative, it means the number reflecting the score is to the left from zero on the number line.
Since Isabel's score is to the left from the Jada's score, she has lower score than Jada.
With the lowest score, Isabel is the winner.
