Answer:
= 250
Step-by-step explanation:
To obtain any term in the geometric sequence multiply the previous term by the common ratio r
here r = - 5 and
= - 2, hence
= - 2 × - 5 = 10
= 10 × - 5 = - 50
= - 50 × - 5 = 250
To get 10 % you have to divide by 10 .
so 154.99 ÷ 10 = 15.499.
that's 10% but you want 20% so you times 10% by 2.
15.499 X 2 = 30.998.
154.99 - 30.998 = 123.992.
you then need to round the answer so you get $123.99
Hope this helps!!
Is C and D because 10x^2-6x^2=36+64
4x^2=100
x^2=25
x= -5 or 5
Answer:
12.4 gallons
Step-by-step explanation:
65 mph x 4 hours means the car went 260 miles. Divide by 21 to get the number of gallons. 12.4 gallons.
Answer: The equation that represents the give situation is, y = 0.75 x + 12
Step-by-step explanation:
Here, x represents the number of batteries the child bought and y represents the total cost.
Since, the cost of one batteries = $ 0.75
⇒ The cost of x batteries = 0.75 x
The cost of one toy = $ 12
Hence, the total cost = The cost of one toy + The cost of x batteries
= y = 0.75 x + 12
Which is the required equation that represents the given situation.
