Answer:
after 6 weeks
Step-by-step explanation:
Sid and Tim starts saving each week.
Sid starts his savings with initial amount of £13.00
Tim starts his saving with initial amount of £00.00
Each week from now Sid will save = £3.50
Tim will save each week = £3.00
Let's assume after 'x' weeks the amount of Sid would be = £ (13 + 3.50x)
and the amount of Tim's saving after x weeks = £ (3x)
The ratio of their savings in x weeks would be = 17 : 9
Now the expression we get,
(13 + 3.50x) : (3x) = 17 : 9
9(13 + 3.50x) = 17(3x)
117 + 31.5x = 51x
117 = 51x - 31.5x
117 = 19.5x
x = 6
After 6 weeks the savings of Tim and Sid would be in the ratio of 17 : 9.
Answer:
the vertices of point R could be (-2,5) or (-2,9)
each point is 7 units away from Q since there are 7 units between P and Q
Step-by-step explanation:
.01 grams because it is 10 mg and 10 mg is .01 grams
First of all, Jamie's room is really weird. Second of all, let's solve. Since the formula for the area of a circle is (pi)r^2, and Jamie's room is exactly half of that, the area for a semicircle would be (1/2)(pi)r^2. The straight wall is the diameter, so half of the diameter would be the radius. Half of 14 is 7. Now, you rewrite the equation and substitute the values of the variables. The new equation (if you're using 3.14 for pi) is (1/2)(3.14)(7^2), or (1/2)(3.14)(49). From here you can solve, so the answer would be 76.93. Jamie needs 76.93 square feet of carpet.
