The sum of the digits of a two-digit number is 7. When the digits are reversed, the number increases by 45. What is the original number?

original number: ⬜

Answers

Answer 1

The original number is 25.

We know that,

The sum of the original number is 7 --(i)

When reversed, the value of the number is increased by 45 --(ii)

Therefore, adding (i) and (ii), we get:

7 + 45 = 52

Also, 5 + 2 = 7

Since 52 is the reversed number,

Therefore, the original number is 25.

What is the value of log2 log32?

Answers

the value of log2 log32 is 0.5899 and  the base of the logarithm is raised to the value that was equated earlier and this expression is equal to the logarithm.

logarithm, the exponent or power to which a base must be raised to yield a given number. Expressed mathematically, x is the logarithm of n to the base b if bx = n, in which case one writes x = logb n. For example, 23 = 8; therefore, 3 is the logarithm of 8 to base 2, or 3 = log2 8.J

The logarithmic equation that has the same solution as x-4=2^3 is log2(x-4)=3.

Logarithm

The logarithm of a number can be calculated from the following relationship:

Thus, the base of the logarithm is raised to the value that was equated earlier and this expression is equal to the logarithm.

So, we have that the third expression

Therefore, this expression is the one corresponding to x-4=2^3.

How do you solve a 3 by 3 system of equations using matrices?

Answers

The solutions can be read off of the diagonal entries in the reduced matrix.

To solve a 3 x 3 system of equations using matrices, first we need to create the augmented matrix for the system of equations. The augmented matrix contains the coefficients of the variables and the constants for each equation on each row. Then we can use row operations to reduce the augmented matrix to reduced row-echelon form. This can be done by adding or subtracting rows to each other, multiplying or dividing a row by a non-zero number, and swapping two rows. After reducing the matrix to row-echelon form, we can back-substitute the solutions to the system of equations. The solutions can be read off of the diagonal entries in the reduced matrix. For example, if the matrix is reduced to the form [a b c d e f g h i] then the solution to the system of equations is x = d/a, y = e/b, and z = f/c.

To find:

The factor of the given expression by GCF.

Solution:

It is given that,

[tex]6x^2+3x+21[/tex]

The terms of the given expression are [tex]6x^2,3x,21[/tex]. The greatest common factor of these terms is 3.

[tex]6x^2+3x+21=3\times 2x^2+3\times x+3\times 7[/tex]

So, taking out the GCF, the given expression can be rewritten as:

Therefore, the factor form of the given expression by GCF is [tex]3(2x^2+x+7)[/tex].

45. Sliding Down a Hill


Ojemba is sitting on a sled on the side of

a hill inclined at 60°. The combined weight of Ojemba and the

sled is 160 pounds. What is the magnitude of the force required

for Mandisa to keep the sled from sliding down the hill?

Answers

If Ojemba is sitting on a sled on the side of a hill inclined at 60° and  weight of Ojemba and sled is 160 pounds , then magnitude of force needed for Mandisa to keep sled from sliding down the hill is 355.59 N   .

the inclination angle of the the side of the hill is = 60° ;

the compound mass of Ojemba and Sled is = 160 pounds ,

On conversion we get the mass in Kg is = 72.57 Kg .

the acceleration due to gravity is , [tex]g = 9.8 m/s^{2}[/tex] ;

The force required for Mandisa to keep sled from sliding down the hill can be calculated by the formula ;

[tex]F = mgSin\theta[/tex] , Substituting the values ,

we get ;

[tex]F = 72.57\times 9.8\times Sin(30\textdegree)[/tex]

[tex]F = 72.57\times 9.8\times \frac{1}{2}[/tex] ;

Kyle and Steve start at the same point and walk in opposite directions. If Kyle walks at 2 mph and Steve walks at 2 mph, how far apart will they be after 3 hours?

Answers

Answer:

12 miles

Step-by-step explanation:

Kyle's speed = 2 mph

Steve's speed = 2 mph

Time traveled = 3 hours

Distance apart after 3 hours

Distance moved by Kyle + Distance moved by Steve

Distance = Speed * time

Distance moved by Kyle = 2 * 3 = 6 miles

Distance moved by Steve = 2 * 3 = 6 miles

Total distance apart = 6 + 6 = 12 miles

What is an inverse function?

First to be an inverse function that function needs to one to one function, meaning every different preimage must correspond to a different image.

We can obtain the inverse of a function by switching the variables x and y with their respective positions and solving for y in terms of x.

Given, k(x) = 4 ÷ 5x - 6.

k(x) = (4/5x) - 6.

Let, y = k(x).

y =  (4/5x) - 6.

(4/5x) = y + 6.

1/x = 5(y + 6)/4.

x = 4/{5(y + 6)}.

y = 4/{5(x + 6)}.

k⁻¹(x) = 4/{5(x + 6)}.

k⁻¹(8) = 4/{5(8 + 6)}.

k⁻¹(8) = 4/{5(14)}.

k⁻¹(8) = 4/70.

k⁻¹(8) = 2/35.

Side AD in ∆ADB is congruent to side AD in ∆ADC.

Side BD in ∆ADB is congruent to side CD in ∆ADC.

Side AB in ∆ADB is congruent to side AC in ∆ADC.

FOR 20 POINTS FIND X PLEASE!!

Answers

Hi there!

We can find the values of x using right triangle trig.

Recall: SOHCAHTOA

sin = O/H (Opposite / Hypotenuse)

cos = A/H (Adjacent / Hypotenuse)

tan = O/A (Opposite / Adjacent)

Thus:

6. A = 14, H = 15

cos x = 14/15

cos⁻¹ (14/15) = x

x = 21.04° ≈ 21°

7. O = 19, A = 23

tan x = 19/23

tan⁻¹(19/23) = x

x = 39.56° ≈ 40°

8. A = 9, H = 17

cos x = 9/17

cos⁻¹(9/17) = x

x = 58.03 ≈ 58°

9. O = 43, H = 45

sin x = 43/45

sin⁻¹(43/45) = x

x = 72.85° ≈ 73°

Answer:

Consecutive odd numbers will be 11 and 13.

Step-by-step explanation:

Let the two consecutive odd integers are n and (n + 2).

From the given question,

Sum between twice the smallest and the biggest is 35.

Since, smallest number is 'n' and biggest is (n + 2)

Therefore equation will be,

2n + (n + 2) = 35

(2n + n) + 2 = 35

3n + 2 = 35

3n = 33

n = 11

And (n + 2) = 13

Consecutive odd numbers will be,
