Joyce saved $70 on an item that was 75 % % off. What was the original price?

SashulF [63]

if Joyce saved $70

at 75% off, Joyce saved 25%

so, $70 is 25%

To find the total price which is 100%, multiply $70 by 4 ( because 25% x 4 = 100% )

so the original price is $70 x 4 = $280

Which of the following is true of algorithms and heuristics for solving real-life problems?

professor190 [17]

Answer: Under the given option, the following is true of algorithms and heuristics for solving real-life problems: Heuristics are shortcut strategies. 

Algorithms are known as step by step plan of action for resolving a issue. It leads to a specific solution, methodically.

whereas;

Heuristics are known as short‐cut, step‐saving reasoning scheme or generalization that bring forth a solution speedily but possibly with an error.

Therefore, the correct option is (a)

What is the explicit formula for this sequence?

ddd [48]

Answer:

$a_n=-7+4(n-1)$

$a_n=-7+(n-1)(4)$

Step-by-step explanation:

-7,-3,1,5,... is a arithmetic sequence.

Arithmetic sequences have a common difference. That is, it is going up by 4 each time.

When you see arithmetic sequence, you should think linear equation.

The point-slope form of a line is $y-y_1=m(x-x_1)$ .

m is the common difference, the slope.

Any they are using the point at x=1 in the point slope form. So they are using (1,-7).

So let's put this into our point-slope form:

$y-(-7)=4(x-1)$

$y+7=4(x-1)$

Subtract 7 on both sides:

$y=-7+4(x-1)$

So your answer is

$a_n=-7+4(n-1)$

Answer:

Step-by-step explanation:

perpendicular (P) = 6

base (b) = 8

hypotenuse (h) =?

we know by using Pythagoras theorem,

h = $\sqrt{(p)^{2} + (b)^{2} } \\$

= $\sqrt{(6)^{2} + (8)^{2} } \\$

= 10
