Answer: $104

Step-by-step explanation:

First you have to find 30% of 80. If 100% is 80, then 10% is 8. To get 30%, multiply 8 by 3 to get 24. So if 30% of 80 is 24, and you need to find the new price of the shoes because they were marked up 30%, then add 24 to the original priceof 80. $80+$24=$104

Solve −3x2 − 4x − 4 = 0
kkurt [141]
This is a quadratic formula with a general form of a²x + bx + c = 0. For quadratic equations, we can solve for its two roots using the quadratic formula shown in the attached picture.

a = -3
b = -4
c = -4

x = [-(-4) + √(-4)² - 4(-3)(-4)]/2(-3) = <em>2 + √-32/2</em>
x = [-(-4) - √(-4)² - 4(-3)(-4)]/2(-3) =<em> 2 - √-32/2</em>

an article when sold at a profit of 5% yields rupees 50 more than when sold at a loss of 5% what was the cost price of the artic
ziro4ka [17]

I'm going to assume that the question should say “at a profit of 5%”.

Restate question in the form of a equation.

Let C = the cost price of the item.

C + 0.705 C = C - 0.05 C + Rs 50

0.05 C = - 0.05 C + Rs 50

0.10 C = Rs 50

C = Rs 500

The cost price of the item is Rs 500

I hope this help you

Rudiy27

Answer:

Step-by-step explanation:

Answer for #5

Two Points M(-7,1) and N(5,1).

1. Formula is Distance = \sqrt{(x2-x1)^2 - (y2-y1)^2}

2. Let’s say (x1,y1) = (-7,1) and (x2,y2) =(5,1)

3. Distance = \sqrt{(5-(-7))^2 + (1-1)^2} = \sqrt{(5+7)^2-(0)^2} = \sqrt{(12)^2+0} =\sqrt{144} = 12}

so distance between two warehouses is 12 miles

Answer #6

In the question it is saying the “Distance between two stores is half the distance between warehouses“ so it is   \frac{12}{2} = 6 miles

Answer #7

S1(-4,1) and distance of S1 and M is 3 Miles.

Answer #8

S2(2,1) and distance of S2 and M is 3 miles.
