a football is selling for 35% off the original price. the original price was $60. what is the sale price of the football.

Answers

The percentage is calculated by dividing the required value by the totalvalue and multiplying by 100.

Example:

Requiredpercentage value = a

totalvalue = b

Percentage = a/b x 100

100% = $60

35% = $21

The saleprice of the football is $21

What is a percentage?

The percentage is calculated by dividing the required value by the totalvalue and multiplying by 100.

Requiredpercentage value = a

totalvalue = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

Originalprice = $60

Sellingprice.

= 35% of $60

= 35/100 x 60

= 7 x 3

= $21

We can also find this way.

100% = $60

35% = 35/100 x $60

35% = $21

Thus,

100% = $60

35% = $21

The saleprice of the football is $21

35% is the same as 0.35
The word "of" in math basically means multiply.
So if 0.35 of 60 is how much is off the original price, then you multiply 0.35 by 60.
=21. So 21 is how much you save. Take 60 and subtract 21 is the answer.

Simplify the expression

Answers

Answer:

The simplified form of given expression $\frac{15xy}{5x^{(1)/(2)}y^2}$ is $\frac{3x^{(1)/(2)}}{y}$

Step-by-step explanation:

Given: Expression $\frac{15xy}{5x^{(1)/(2)}y^2}$

We have to write the given expression in simplified form,

Consider the given expression $\frac{15xy}{5x^{(1)/(2)}y^2}$

Divide the numbers $(15)/(5)=3$

we get,

$=\frac{3xy}{y^2x^{(1)/(2)}}$

Apply exponent rule , $(x^a)/(x^b)\:=\:x^(a-b)$

$\frac{x}{x^{(1)/(2)}}=x^{1-(1)/(2)}=x^{(1)/(2)}$

we get,

$=\frac{3yx^{(1)/(2)}}{y^2}$

Cancel y term, we have,

$=\frac{3x^{(1)/(2)}}{y}$

Thus, The simplified form of given expression $\frac{15xy}{5x^{(1)/(2)}y^2}$ is $\frac{3x^{(1)/(2)}}{y}$

Answer:

$3x^{(1)/(2)}y^(-1)$

Step-by-step explanation:

The given expression is:

$\frac{15xy}{5x^{(1)/(2)}y^2}$

We have to simplify the above given expression.Thus,

Firstly, divide the constant terms, we get

$(15)/(5)=3$

Now, applying the exponent law, that is $(x^a)/(x^b)=x^(a-b)$ , we have

$\frac{xy}{x^{(1)/(2)}y^2}=x^{1-(1)/(2)}y^(1-2)=x^{(1)/(2)}y^(-1)$

Thus, the simplified form of the above given equation is:

$3x^{(1)/(2)}y^(-1)$

(9 – 6i) × m = 9 – 6i What is m?

a. 0

b. 1

c. 9 + 6i

d. -9 + 6i

Answers

An equation is formed of two equal expressions. In the given equation (9–6i)×m = 9–6i, the value of m is 1.

What is an equation?

An equation is formed when two equal expressions are equated together with the help of an equal sign '='.

In the given equation (9–6i)×m = 9–6i, the value of m can be found as,

(9–6i)×m = 9–6i

Divide both the sides of the equation by (9–6i),

$((9-6i)* m )/((9-6i))= ((9-6i))/((9-6i))\n$

m = 1

Hence, In the given equation (9–6i)×m = 9–6i, the value of m is 1.

A plane, parallel to the base of a cone intersects the cone at the midpoint between points A and B. Determine the area of the cross-section formed by the intersection of the plane and the cone. Leave your answer in terms of pi. 2o height 6 radiusA) 1.5π in2
Eliminate
B) 3π in2
C) 9π in2
D) 36π in2

Answers

Answer:

Area of cross-section is $9\pi in^(2)$

Step-by-step explanation:

Given a cone and a plane parallel to base intersect the cone at the mid point of points between A and B.

We have to find the area of cross-section formed by intersection of the plane and the cone which is a new circle formed.

Given, height=20 in

radius=6 in

By mid point theorem i.e the line segment formed by joining the mid points of two side of triangle is parallel to third equal to half of the third side.

therefore new circle formed is of radius 3 in

Hence, area of cross-section formed by intersection of the plane and the cone which is a new circle formed= $\pir^(2)$

= $3^(2)\pi$

= $9\pi$ $in^(2)$

A manufacturing process is designed to produce bolts with a 0.75-inch diameter. Once each day, a random sample of 36 bolts is selected and the bolt diameters recorded. If the resulting sample mean is less than 0.730 inches or greater than 0.770 inches, the process is shut down for adjustment. The standard deviation for diameter is 0.04 inches. What is the probability that the manufacturing line will be shut down unnecessarily? (Hint: Find the probability of observing an x in the shutdown range when the true process mean really is 0.75 inches. Round your answer to four decimal places.)
