Answer:
Step-by-step explanation:
Given that Drake wants to save $750 so that he can take a class on computer analysis for cars.
He wants to save 125 per week for 6 weeks.
.Unfortunately, Drake had to take out a little money from his savings in the 3rd week. After 4 weeks, Drake has $470.
If he wants to have 750 after 6 weeks, he has to save $ per week
Or alternately he can save same 125 dollars so that he would have 750 $ in
3 weeks.
A: Stay with saving the original amount each week but take the class a week later than originally planned.Option B: Increase the amount of money he saves each week by $15 from his original plan.
Both are right.
c. Both options A and B will allow him to meet his goal.
Answer:
The area is 83.905 cm^3
Step-by-step explanation:
The total ratio is 9 + 7 + 6 = 22
So the length of the sides are as follows;
9/22 * 44 = 18 cm
7/22 * 44 = 14 cm
6/22 * 44 = 12cm
we can use Heron’s formula to find the area of the triangle
we find a first
s = (a + b + c)/2 = (18+14+12)/2 = 44/2 = 22
Mathematically, the Heron’s formula is as follows;
A = √s(s-a)(s-b)(s-c)
where a, b and c are 18,14 and 12 respectively
Plugging the values, we have;
A = √22(22-18)(22-14)(22-12)
A = √(22 * 4 * 8 * 10)
A = √(7,040)
A = 83.905 cm^3
The answer is: 1.2871428714...
The area formula for a rectangle is A = L*W. We have the area as 3197, now we just have to find a way to directly relate the length to the width with only one unknown, since we can't have 2 unknowns. The problem tells us that the length is 22 in. less than 7xW. That will be expressed as L=7W-22, and width is just W. Filling in we have 3197=W(7W-22). Distributing through the parenthesis we have
. Since we have to solve for x and the only way we can do that is by factoring, we will move the 3197 over to the other side by subtraction and then factor the quadratic.
. I recommend putting that into the quadratic formula, and when you do you get W values of 23 and -19.857 The only 2 things in math that will never EVER be negative are time and distance/length. And since one of our lengths there is negative we know that that is not the one we will use. Therefore, the width is 23. The length then is L=7(23)-22 which is 139
