how many solutions does this problem have: 2(75 + 8) = 5(85 + 9)​

Answer:

Step-by-step explanation:

Let total shirts be x.

Then, Striped shirts = 1/9x

Remaining Shirts= 8/9x

Therefore, Printed Shirts = 5/8 × 8/9x

= 5/9x

Remaining Shirts

or

Plain Shirts= x - ( 5/9x + 1/9x )

= 3/9x

Acc. to problem,

Plain Shirts=81

Therefore,

3/9x=81

=> x=81×9/3

=> x=27×9=243

Therefore,

Total Shirts= 243

28/32=0.875

0.875*100= 87.5

87.5% of 32 = 28

Answer:

A

Step-by-step explanation:

He increased by 10% because of 80% to 90% is 10%

So, the Answer  is A

Answer:

12.5%

Step-by-step explanation:

The question is asking for the percent increase of 80%. So how much of 80% was the new percentage (90%) increased by.

First, find the difference 90-80=10

Then find the percent of 80 that the difference is.

10/80=0.125

0.125 in a percent form is 12.5%

So, there was a 12.5% increase.

The cost of hot dogs are 1.25 and the cost of hamburgers are 1.50.

Let x=hot dogs a/

Let y = hamburgers

x + 7y = 11.75

x + y = 2.75

Subtract the second equation from the first.

x + 7y = 11.75

-(x + y = 2.75)

------------------------

      6y = 9.50

     divide by 6

       y = 1.50

Substitute the y value in the simplest equation to solve for  x

x +   y   = 2.75

x + 1.50= 2.75

   -1.50   -1.50

x = 1.25

Hot dogs are 1.25 and hamburgers are 1.50.

The line which shows another way to name the ray LR is line: LD.

A line segment can be defined as the part of a line in a geometric figure such as a triangle, circle, quadrilateral, etc., that is bounded by two (2) distinct points and it typically has a fixed length.

Collinear points can be defined as three or more points that all lie on the same straight line (single line). Based on the geometric figures shown in the image below, the three collinear points include the following:

The probability that a defective product was found by the first inspector is 80% since the first inspector catches 80% of the defectives.

Probability is a linear scale measurement of the likelihood of an outcome occurring out of many possible outcomes.

Probability refers to the chance that something or an event happens when other events could have occurred.

Probability is measured in percentages, fractions, or decimals.  The probability of an outcome does not exceed one.  When it is one, it shows that the event is certainly going to happen.

Percentage of defectives found by the first inspector = 80%

Percentage of defectives not found by the first inspector = 20% (1 - 80%)

Percentage of defectives not found by the second inspector = 40%

Percentage of defectives found by the second inspector = 60% (1 - 40%)

Thus, the probability that a defective product was found by the first inspector is 80% since the first inspector catches 80% of the defectives.

The numbers are 13 and 3.

Let the numbers be x and y. Equation representing difference of these numbers-

x - y = 10 : equation 1

Equation representing product of these numbers- x × y = 39 : equation 2

Rewriting the equation 2 in terms of y

y = 39/x : equation 3

Keeping the value of y from equation 3 in equation 1

x - 39/x = 10

Multiplying the equation by x

x² - 39 = 10x

Rearranging the equation

x² - 10x - 39 = 0

Factorising the equation

x² - 13x + 3x - 39 = 0

x(x - 13) +3 (x - 13) = 0

(x + 3) (x - 13) = 0

Value of x = 13 and -3

Taking positive value of x

Keeping value of x in equation 3

x = 13

y = 39/13

y = 3

Hence, the numbers are 13 and 3.

The value of cotθ where θ is in fourth quadrant is [tex]-\frac{5}{\sqrt{171} }[/tex]  which is option (A).

It is given that cosθ = 5 /14 .        ....(1)

As we know that cosθ  = Base / Hypotenuse     ...(2)

On comparing equation (1) and (2) , we get

Base = 5 and Hypotenuse = 14

Using Pythagorean theorem , we get

          Hypotenuse² = Perpendicular² + Base²

                   14²   = P² + 5²

                   196 = P²  +25

                    171 = P²

Then , cotθ = Base / Perpendicular

Population standard deviation (s) = 13.1

Sample size = 47

Maximal margin of error associated with 90% confidence interval.

The margin of error is given by:

Given the annual deposit amount and annual interest rate, future value of  the annuity in the given period of time is $283,208.03.

Annuity is simply a mechanism to create substantial amount in future by making relatively very small periodic payments up until maturity.

It is expressed mathematically as;

F = P × (( (1+r)^(nt) - 1 )/r)

Given the data in the question;

Plug the given values into the equation above and solve for A.

F = P × (( (1+r)^(nt) - 1 )/r )

F = 2500 × ( ((1 + 0.08 )^(1×30) - 1 ) / 0.08 )

F = 2500 × (( (1.08 )³⁰ - 1 ) / 0.08 )

F = 2500 × ( 10.06265688 - 1)/0.08 )

F = 2500 × ( 9.06265688/0.08 )

Explanation:

Rule: We cannot divide by zero.

Because of that rule, we'll set the denominator equal to zero and solve for x. This way we can determine the x value(s) that are to be excluded from the domain.

6 - |x-1| = 0

|x-1| = 6

x-1 = 6 or x-1 = -6

x = 6+1 or x = -6+1

x = 7 or x = -5

Those x values are to be excluded from the domain, since they make the denominator zero.

Imagine a number line in which we poked open holes at -5 and 7

Combining everything gets us x < -5; -5 < x < 7; x > 7
