Find the discount if a $69.99 item is on sale for $39.99

Answers

Answer 1

Answer: ok so discount is how much you have to minus from the original to get the sale price
69.99=original
39.99=sale price
so
origial-discount=sale
69.99-discount=39.99
subtract 69.99 from both sides
-discount=-30
multiply by -1
discount=30

answer is $30.00

Answer 2

Answer: If you wanna find the discount the only thing you should do is to say:
69.99 - 39.99 = $30 :)))

Perimeter of the Rectangle

The perimeter of the rectangle is twice the sum of its length and breadth.

$\rm{Perimeter = 2(length +breadth)$

Area of the rectangle

the area of the rectangle is given as the product of its length and its breadth.

$\rm{Area ={length* breadth$

Given to us

Permeter = 26 cm

Perimeter

$\rm{Perimeter = 2(length +breadth)$

$26 = 2(length +breadth)$

$13=(length +breadth)$

Area of the rectangle

As we know that the area is given as the product of length and breadth. so, we need to find those numbers whose sum is 13. while their product gives us the maximum area.

Therefore, for the area to be maximum the length and breadth should be maximum.

$1 * 12 = 12\n2* 11 = 22\n3* 10 = 30\n4* 9 = 36\n5* 8 = 40\n6* 7 = 42$

Thus, the length should be 7 while the breadth should be 6 to maximize the area.

Answer:

1. One way to show that a statement is not a good definition is to find a counterexample. A counterexample refers to an exception to the rule, if we deduct that exception is true, then the proposition is completely false. In this case, we have to find an exception to the definition, if the exception is true, then the definition is not true.

2. The option that show a true conditional is the fourth: If it's raining, then the humidity level is 100%. This shows the correct logical conditional, other options are not logical. In this case, the hypothesis is "if it's raining", and the conclusion is "the humidity is 100%". This is the right order, because humidity derive from raining, not the opposite.

The true conditional with a correctly identified hypothesis is:

If it is raining, then the humidity level is 100%.

Hypothesis: It is raining.

Conclusion: The humidity level is 100%.

1. One way to show that a statement isn't a good description is to find a counterexample.

A counterexample refers to an exception to the rule, if we abate that exception is true, also the proposition is fully false. In this case, we've to find an exception to the description, if the exception is true, also the description isn't true.

2. The option that show a true tentative is the fourth If it's raining, also the moisture position is 100.

This shows the correct logical tentative, other options aren't logical. In this case, the thesis is" if it's raining", and the conclusion is" the moisture is 100". This is the right order, because moisture decide from raining, not the contrary.

65 Points - I have class in 1hr and I still can't figure this out... pls give full explanation and correct answer or else you'll be reported for "point greediness" --- thx ya'llAB is tangent to the circle k(O) at B, and ADis a secant, which goes through O. Point O is between A and D∈k(O). Find m∠BAD and m∠ADB, if measure of arc BD is 110°20'.

Answers

Sounds like the situation in the sketch below...

There is a theorem that says the angle (BAD) formed by a tangent (AB) and a secant (AD) to a circle (O) is half the difference of the intercepted arcs (BD and BD'):

$m\angle BAD=\frac{110^\circ20'-69^\circ40'}2=40^\circ40'$

Triangle BAD is a right triangle, so

$m\angle ADB=90^\circ-m\angle BAD=49^\circ20'$

If 4/3x - 1/2 = 0 then x=

Answers

4/3x - 1/2 = 0 Given
4/3x = 1/2 Add 1/2 to both sides
x = 3/8 Multiply each side by 3/4

It is important when doing equations like these to remember that you need to multiply by the reciprocal of the fraction, not divide by it. For example, if another you have 1/2x = 1, you need to multiply by 2/1 or 2, not divide by 1/2.

12 litres of water are poured into an aquarium of dimensions 50cm length, 30cm breadth, and 40cm height. How high (in cm) will the water rise? (1 litre = 1000cm3)a. 6
b. 8
c. 10
d. 20
e. 40

Answers

So, first you want to find the area of the base of the tank. This is the length times the breadth (or height, same thing). 50 x 30 = 1500. This means that it will take 1500cm3 (1.5 litres) of water for each centimeter of height. 1.5 x 8 = 12, so it would rise 8 centimeters.

The water will rise to 8 cm (B)
