Find the value of x.

Answer:

67

Step-by-step explanation:

Number: AB

A = B-1

BA + AB = 143

10*B + A + 10*A + B = 143

11A + 11B = 143

A + B = 13

(B-1) + B = 13

2B = 14

B = 7

A = 6

The number is 67

check: 6 = 7-1   and   67 + 76 = 143

Answer:

slope is 4

y-intercept is -7

x-intercept is 7/4

Answer:

[tex]12ab[/tex]

Step-by-step explanation:

3a × 2b = 6ab

6ab × 2 = 12ab

Therefor, the answer is 12ab.

3a × 2b × 2 = 12ab

The expression expects us to find the product . Therefore,

Let's do it step by step

3a × 2b = 6ab

Then,

6ab × 2 = 12ab

Therefore,

3a × 2b × 2 = 12ab

Answer:

10.8 minutes

Step-by-step explanation:

Given data

We are told that the number of Jugs is 18

Filling the first 3 jugs has taken 5 minutes

let us find the filling rate

Rate= 3/5

Rate= 0.6 Jugs per minute

Hence the rate of filling is 0.6 Jugs per minute

Therefore the time take to fill the remaining 16 jugs is

TIme= Rate*Number of Jugs

TIme= 0.6*18

Time= 10.8 minutes

Answer:

(1,-3.7)

Step-by-step explanation:

subtract the y axis to go down

5 - 8.7 = -3.7

The solution is B ( 1 , -3.7 )

The coordinates of the zombie is given by B ( 1 , -3.7 )

How does the transformation of a function happen?

The transformation of a function may involve any change.

Usually, these can be shifted horizontally (by transforming inputs) or vertically (by transforming output), stretched (multiplying outputs or inputs), etc.

If the original function is y = f(x), assuming the horizontal axis is the input axis and the vertical is for outputs, then:

Horizontal shift (also called phase shift):

Left shift by c units:  y=f(x+c) (same output, but c units earlier)

Right shift by c units:  y=f(x-c)(same output, but c units late)

Vertical shift:

Up by d units: y = f(x) + d

Down by d units: y = f(x) - d

Stretching:

Vertical stretch by a factor k: y = k × f(x)

Horizontal stretch by a factor k: y = f(x/k)

Given data ,

Let the initial point of the man be A

The value of A = A ( 1 , 5 )

Let the coordinates of the zombie be B

The value of B = B ( x , y )

The zombie is 8.7 units below

So , it is a vertical shift by 8.7 units

Therefore , the y coordinate will decrease by 8.7 units

Substituting the values in the equation , we get

B = A ( 1 , 5 - 8.7 )

B = B ( 1 , -3.7 )

Therefore , the value of B is B ( 1 , -3.7 )

Hence , the coordinates of B is B ( 1 , -3.7 )

Answer:Number of cellos  =7

Step-by-step explanation:

The ratio of cellos to violins is 1 to 3=1:3

Total ratio = 1+3=4

To find the total number of  cellos and violins in the orchestrs,

Ratio of violins/ Total ratio  x Total number of cellos and violins  = Number of violins

3/4  x X= 21

X=21 x 4 / 3

X =7x 4  28.

Answer:

BC = 5.87

Step-by-step explanation:

Reference angle = 50°

Side Opposite to reference angle = 7

Adjacent side = BC = ?

Apply trigonometric function, TOA, thus:

Tan 50 = Opp/Adj

Tan 50 = 7/BC

BC × Tan 50 = 7

BC = 7/Tan 50

BC = 5.87369742 ≈ 5.87 (nearest hundredth)

Answer:

1.)   ((a+1)^3)+(x^3)  = a^3 + 3a^2 + 3a + x^3 + 1

2.)  ((y-2)^3)-27  =   (y^2-y + 7) x ( y - 5 )

3.)   ((a-b)^3)+b^3  = a (a^2 - 3ab + 3b^2 )

4.)   (8x^3)+((x-y)^3)  =  9x^3 -3x^2 y + 3xy^2 - y^3

5.)   (27a^3)-((a-b)^3) = 26a^3 + 3a^2 b - 3ab^2 + b^3

5) factor = (a+b)(a+b)^ 2    if a is squared and if b is cubed and moved over to = 0 then we can find (a+b)(a+b)^2 but in all cases of quadratics you can set (x -1 ) = 1 and (x-1 ) = 1  so they are always positive. Which is the same if they start of negative.

For question 5 we have a factor solved (a+b)(a+b)^ 2

Which means the same as this expansion

Answer:

the average distance from the mean is 84.8

Step-by-step explanation:

The computation of the average distance from the mean is shown below;

= Total sum ÷ number of observations

= (80 + 76 + 88 + 96+ 75 + 83 + 68 + 94 + 99 + 89) ÷ (10)

= 848 ÷ 10

= 84.8

Hence, the average distance from the mean is 84.8

Answer:

x = 252°, y = 126° , z = 54°

Step-by-step explanation:

( Hopefully I've read the size of the angle 126° correctly )

The central angle x is twice the inscribed angle, that is

x = 2 × 126° = 252°

∠ y = 126° ( angles on the circumference subtended by the same arc )

y and z are adjacent angles and are supplementary , that is

y + z = 180°

126° + z = 180° ( subtract 126° from both sides )

z = 54°

Answer:

It will take 5 months and that height will be 20cm.

Step-by-step explanation:

Let the height of the tree be h cm and the number of months be m.

Maple tree

Initial height= 10cm

Total height= 10cm +2(number of months)

h= 2m +10 -----(1)

Oak tree

Initial height= 15cm

Total height= 15cm +1(number of months)

h= m +15 -----(2)

When the height of the two trees are the same,

2m +10= m +15

Solve for m:

2m -m= 15 -10

m= 5

Substitute m=5 into either equation 1 or 2 to obtain the height.

When m=5,

h= 5 +15

h= 20

Answer:

11/21.

BG has a total of 11 points (when you include 0), and there are 21 points total. 11/21 cannot be simplified, your final answer is 11/21.

The required probability is 11/21 that one point will be on BG.

Probability is defined as the possibility of an event being equal to the ratio of the number of favorable outcomes and the total number of outcomes.

We have been given that the number line which has a point is chosen at random on AK.

As per the given question, the required solution would be as:

Since BG has a total of 11 points (when you include 0),

so, the number of favorable outcomes : 11

There are 21 points in total, then the total number of outcomes : 21.

So, the probability that one point will be on BG would be as:

⇒ 11/21
