the sum of two digit number and the number obtained by reversing its digit is 154 if the digit differ from 4 find the number​

Answers

Answer 1

Answer:

The number is either 95 or 59

Step-by-step explanation:

The two digit number would be;

(10a + b)

The reversal will be (10b + a)

The sum of the two is 154

(10a + b ) + (10b + a) = 154

11a + 11b = 154

11(a + b) = 154

a + b = 14 ••••••••(i)

The difference between the two digits is 4

Let’s have this as;

a - b = 4 ••••(ii)

from ii;

a = 4 + b

Substitute this into equation i

4 + b + b = 14

2b = 14-4

2b = 10

b = 10/2

b = 5

Recall;

a = b + 4

a = 5 + 4

a = 9

So we have the number as 95 or 59

Sandy has a total of 35 coins in her money jar. If Sandy's jar contains only nickels and dimes and the value ol
the coins is $2.50, how many nickels does Sandy have?

Answers

you'll have to solve simultaneously

let nickel be x, dime be y

x + y = 35 ... ( 1 )

5x + 10 y = 250
5 ( x + 2y ) = 250
x + 2y = 50 ... ( 2 )

in ( 1 )
x = 35 - y ( 3 )

sub ( 3 ) into ( 2 )
( 35 - y ) + 2y = 50
y = 15

sub y into ( 1 )
x + y = 35
x + 15 = 35
x = 20

therefore, Sandy has 20 nickels and 15 dimes

Is this proportional or non proportional and why

Answers

Given:

The table of values.

To find:

Whether the given relation in the table is proportional or non proportional.

Solution:

If y is directly proportional to x, then

[tex]y\propto x[/tex]

[tex]y=kx[/tex]

[tex]\dfrac{y}{x}=k[/tex]

Where, k is the constant of proportionality.

It means the ratio of y and x remains same for proportional relation.

From the given table, the points are (10,18), (11,18.6) and (12,19.2). The ratio of y to x for these points are:

[tex]\dfrac{18}{10}=1.8[/tex]

[tex]\dfrac{18.6}{11}\approx 1.69[/tex]

[tex]\dfrac{19.2}{12}=1.6[/tex]

Since the ratio of y to x for the given points are not equal, therefore the given relation is a non proportional relation.

Answer:

y = -2x + 5 [ 1st option ]

Step-by-step explanation:

Consider any two points , say

(1,3) (2,1)

Firstly let's find the slope of the line as ,

=> m = y₁ - y₂ / x₁ - x₂

=> m = 3-1 / 1-2

=> m = 2/-1

=> m = -2

Third point is, (3 , -1) . Using slope point form .

=> y - y₁ = m ( x - x₁ )

=> y - (-1) = -2( x - 3)

=> y + 1 = -2x +6

=> y +2x +1-6=0

=> y +2x -5 = 0

=> y = -2x + 5

On looking at options first one is correct

Hence the equation of line is y = -2x + 5.

Answer:

[tex]Pr = 0.59049[/tex]

Step-by-step explanation:

See Comment for Complete Question

Given that A has 5 digits. A digit in A can be chosen from 0 to 9 (10 digits).

However, selection without 4 means that we can only select from 0 to 3 and 5 to 9 (altogether, that is 9 digits)

The probability of selecting a number other than 4 in each of the digit is:

[tex]1st \to \frac{9}{10}[/tex]

[tex]2nd \to \frac{9}{10}[/tex]

[tex]3rd \to \frac{9}{10}[/tex]

[tex]4th \to \frac{9}{10}[/tex]

[tex]5th \to \frac{9}{10}[/tex]

So, the required probability is:

[tex]Pr = 1st * 2nd * 3rd * 4th * 5th[/tex]

[tex]Pr = \frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10} *\frac{9}{10}[/tex]

[tex]Pr = \frac{9^5}{10^5}[/tex]

[tex]Pr = \frac{59049}{100000}[/tex]

[tex]Pr = 0.59049[/tex]

A certain television is advertised as a 85 inch TV if the width of the TV is 67 how tall is the TV

Answers

Answer:

Step-by-step explanation:

Apply the Pythagorean Theorem:

85^2 = 67^2 + h^2, where h is the height of the TV

Then 7225 = 4489 + h^2, or

h^2 = 2736, or h = +√2736 = 52.3 inches

The TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.

What is a right-angle triangle?

It is defined as a triangle in which one angle is 90 degrees and the other two angles are acute angles. In a right-angled triangle, the name of the sides are hypotenuse, perpendicular, and base.

We have:

A certain television is advertised as a 85 inch TV

It means the diagonal length is 85 inches.

Width of the TV = 67 inches

Let's suppose the TV is x inches Tall

So from the Pythagoras theorem:

[tex]\rm 85^2 = x^2+67^2[/tex]

7225 = x² + 4489

x = 52.30 inches

Thus, the TV is 52.30 inches tall if the television is advertised as an 85-inch TV if the width of the TV is 67.
