Answer:
Dont know how to exactly explain but
Step-by-step explanation:
Both triangles angle y is 85 i forgot the proof name
Answer:
The inequality to represent this scenario is given as:
7x + 12y ≥ 200
Step-by-step explanation:
From the question:
Daniella has two jobs. She earns $7 per hour babysitting her neighbor's children and she earns $12 per hour working at the coffee shop.
Let:
The number of hours babysitting = (x) The number of hours working at the coffee shop= (y)
We are told in the question that:
Daniella will need to work to earn at least $200.
At least means equal to or greater than
Hence,
The inequality to represent this scenario is given as:
$7 × x + $12 × y ≥ $200
7x + 12y ≥ 200
Answer:
x = 7; y = 77
Step-by-step explanation:
y = 9x + 14
y = 4x + 49
Since both equations are solved for y, set the two right sides equal and solve for x.
9x + 14 = 4x + 49
5x = 35
x = 7
Sow substitute 7 for x in the first equation and solve for y.
y = 9x + 14
y = 9(7) + 14
y = 63 + 14
y = 77
Answer: x = 7; y = 77
Step-by-step explanation:
Ok, so, to find this, remember- to find the true price of an item, remember the equation (PRICE DIVIDED BY QUANTITY), this will give you true price. So, for the individual, its $3.99 for one pound. In bulk, to find the true price, do price divided by quantity. $17.45/5= 3.45. So thats the better deal. Anyways, to find out how much cheaper it is, subtract 3.45 from 3.99. The answer is .54, however, since you need to round to the nearest tenth place, the answer would be .50
We know that the interest decreased by 29.3%, therefore
what was left now is simply just 70.7% of the original, therefore we divide
this by 0.707
rate = 7.7% / 0.707
rate = 10.89%
<span>So the rate was 10.89% 10 years ago</span>
