Answer:
499.2
cm²
Step-by-step explanation:
See attachment for the figure.
The area of a triangle is given by
A = 1/2bh
A = 1/2(12)(10.4)
A = 62.4
cm²
Then, take that area and multiply it by the number of faces. In this problem, there are 8.
62.4 × 8 = 499.2
cm²
Answer:
1. h,k
2. -3, -5
3. 1, 7
4. 9, -2
5. -4, -6
Step-by-step explanation:
Don’t worry! I am happy to help you! Standard form is just the number alone. In this case, here are the numbers written out for you.
1. 53
2. 9,400
3. 707,000
4. 0.0026
5. 0.08651
6. 0.0000067
The next part here is scientific notation. The first number has to be greater than 1, but less than ten, and the number you multiply by is powers of 10, sometime positively and sometimes negatively. You can search up the powers of 10 chart to find more. Here they are written in scientific notation.
7. 5.61 * 10^3
8. 1.4 * 10^1
9. 5.64 * 10^7
10. 7.52 * 10^-1
11. 6.4 * 10^-3
12. 5.81 * 10^-4
For this next part, you have to get these answers and express it in scientific notation. Here are these answers with the work.
13. 69,000,000 + 212,000 = 69,212,000.
Scientific notation: 6.9212 * 10^7
14. 43,000 + 521,000 = 564,000
Scientific notation: 5.64 * 10^5
Answer:
168
Step-by-step explanation:
area of base triangle = 6×4= 24÷2= 12
2 triangles= 12×2=24
9×5= 45 ×2=90
6×9 =54
54+90+24=168
Answer:
A. He captured Fort Duquesne.
Step-by-step explanation:
General Edward Braddock was fatally injured in the battle field and died of wounds. He insisted upon using open field tactics which turned out to be very fatal leading to the death of 1000 soldiers. He did ignore the early warnings of his aides regarding his strategy.
A British force led by General Edward Braddock, moving to take Fort Duquesne, was defeated by a force of French and Canadian troops under Captain Daniel Liénard de Beaujeu with its American Indian allies.
Consequently, he failed to capture Fort Duquesne. So statement A is not true.
