Answer:
Nickel= 1.8 kg
Zinc= 0.4 kg
Copper= 1.8 kg
Step-by-step explanation:
7:2:9
7=nickel
2=zinc
9=copper
7+2+9=18
18×2=36
7×2=14 2×2=4 9×2=18
Divide by 10
14÷10=1.4 4÷10=0.4 18÷10=1.8
1.8+1.4+0.4= 3.6
1.8=nickel
0.4=zinc
1.8=copper
Hi There!
Solution,
Point Slope Form: y - y1 = m(x - x1)
Now you have a reference equation of what the answer should look like.
By looking at the answer choices you can eliminate A.
Tip: When you have a negative number you are going to add. For Example, if you have -8, you will input x + 8 or y + 8.
Tip 2: When you have a positive number you are going to subtract. For Example, if you have 3 you will input x - 3 or y - 3.
We can eliminate B because its not subtracting 3.
We can also eliminate C because its not adding -8.
The best answer choice is D.
Answer,
y – 3 = 6(x + 8)
I hope you understand, so you can do this in the future on your own.
Hope This Helps :)
Total= Car Cost + (Car Cost * Tax %)
Total= $16,800 + ($16,800 * 6.25%)
convert % to decimal form; divide % by 100
Total= $16,800 + ($16,800 * 0.0625)
multiply inside parentheses
Total= $16,800 + $1,050
Total= $17,850
ANSWER: The total cost for the used car with tax is $17,850.
Hopd this helps! :)
Answer:
12
Step-by-step explanation:
The least common multiple of {6,8,12} is 24. This can be intuitively figured by noting that any multiple of 12 is a multiple of 6 and that 12 is 1.5x larger than 8. That means we only have so multiple 12 by 2 and 8 by 3 for them to be equal. The GCF of {20,42,72} is 2 as the prime factorization of 20 is 2x2x5 and 42 is 2x3x7. That means even without having to check 72 (which is clearly even so 2 is a factor), we know that 2 is the greatest common factor that they could share. So X/Y = 24/2 = 12
No not really. I’m not having issues with Brainly.
