(SAT Prep) Find the value of x

Answer:

7

Step-by-step explanation:

Answer:

x>5/2

Step-by-step explanation:

Answer:

(6x+10)°=(6x+10)°[vertically opposite angle]

now,

6x+10+10x+10=180°[being cointerior angle]

16x=180-20

x=160%16

x=10°

Answer:

D

Step-by-step explanation:

The standard form for a parabola is ax^2+bx+c. In this equation, b=0 and c=0. For g(x), you would plug in your y-value that was given (which is 4) and you would plug in your x-value that that given (which is 1). Use PEMDAS. The correct answer is the one that is true.

A. g(x) = (4x)^2

4 = (4(1))^2

4 = 16. (not true)

B. g(x) = 1/4 x^2

4 = 1/4 (1)^2

4 = 1/4 (not true)

C. g(x) = 16x^2

4 = 16(1)^2

4 = 16 (not true)

D. g(x) = 4x^2

4 = 4(1)^2

4 = 4. (true --> correct answer)

Answer:

y = 3/2x + 7

Step-by-step explanation:

The slops is rise over run, so in this case the slope is 3/2 because it goes up 3 units while going 2 units to the right.

The points (0,7) is on the y axis. This means that 7 is the y intercept

With this information, we can follow the format of the slope intercept equation: y = mx + b

m stands for the slope and b stands for the y intercept. Plugging the information in, our equation is:

y = 3/2x + 7

Answer:

1.9 Kilograms.

Step-by-step explanation

To find the total, subtract 35 and 44, that equals 9. so take 35 from 44, Thats 1 kilo, plus the 9 extra. 1.9 Kilos

Answer:

the probability is 0.6293

Step-by-step explanation:

The computation of the probability is shown below:

Given that

n = 5

P = 0.18

As it represents the  binomial distribution

P(X = x) =  [tex]^NC_x[/tex]× p^x × (1 - p) ^(n - x)

P(X > 1) = 1 - P(X < 1)

= 1 - P(X = 0)

= 1 - ( [tex]^5C_0[/tex]× (0.18) ^0 × (0.82) ^5)

= 1 - 0.3707

= 0.6293

hence, the probability is 0.6293

Answer:

Step-by-step explanation:

Answer:

86°

Step-by-step explanation:

Given:

 A = (6x + 10)°

 B  =  (4x +30)°

Two angles are supplementary if they sum up to 180° ;

 A + B  = 180°  

 Now insert the parameters and solve;

  6x + 10 + 4x +30 = 180

      10x + 40  = 180

       10x  = 140

           x = 14

So;

    B  =  (4x +30)°  = 4(14) + 30  = 86°

Answer: (x - 5)(x + 4)

Answer:

(x+5)(x+4)

Step-by-step explanation:

Based on the systems of equations given, the number of real solutions for each system is:

To find out the number of solutions, you should plot the equations on a graph.

When system A is plotted as shown attached, you notice that line y = 1/2x intersects x² + y² = 17 twice. It therefore has two solutions.

When system B is plotted, y = -6x + 5 does not intercept y = x² + 7x + 10 which means that there are no real solutions.

System C shows only one real solution because 8x - y = -17 intercepts y = -2x² + 9 once.

14 pink balls

Step-by-step explanation:

you would devide 21 by 3 and that would be 7, then you multiply by 2 and you get 14.

Answer:

Where is the graph?

Step-by-step explanation:

The number of hours taken should be 8.5 hours

And, the distance should be 187 km.

d = 18t + 34

d = 22t

Put the d value in the above equation

22t = 18t + 34

22t - 18t = 34

4t = 34

t = 8.5 hours

Now the distance is

= 22(8.5)

= 187 km

Answer:

C.-85

Step-by-step explanation:

An arithmetic sequence is a sequence where the difference between each consecutive term is the same.

The nth term of an arithmetic sequence.

= a + (n - 1)d

The 61st term of the sequence is 85.

It is a sequence where the difference between each consecutive term is the same.

Example:

2, 4, 6, 8 is an arithmetic sequence.

We have,

-5, -7/2, -2, -1/2, 1

a = -5

d = -7/2 + 5

d = 3/2

Now,

The nth term of an arithmetic sequence.

= a + (n - 1)d

Now,

n = 61

61st term:

=  -5 + (61 - 1)(3/2)

= -5 + 60 x 3/2

= -5 + 30 x 3

= -5 + 90

= 85

Thus,

The 61st term of the sequence is 85.

C. 1/2(154-46) hope this helps :)

Step-by-step explanation:

The measure of the angle XYZ will be [tex]\frac{1}{2} (154^0 -46^0 )[/tex] i.e. option C.

Angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle.

We have,

Arc ST = 46°, and

Arc XZ = 154°

Now,

We know that the measure of the arc is same as that of central angle.

Now,

Join X and T,

Now,

We know that, the angle subtended at the center is the average of the measure of arc intercepted by its angle and its vertical angles.

So,

Angle XTZ [tex]=\frac{154}{2}[/tex]

And,

Angle SXT [tex]=\frac{46}{2}[/tex],

Now,

∠XTZ = ∠XYZ + ∠SXT  [Exterior angle is equal to the sum of interior opposite angles]

So,

∠XYZ = ∠XTZ - ∠SXT

Now,

Substituting the values,

We get,

∠XYZ [tex]=\frac{154}{2}-\frac{46}{2}[/tex]

i.e.

∠XYZ [tex]=\frac{1}{2} (154-46)[/tex]

So, measure of angle XYZ is  [tex]\frac{1}{2} (154-46)[/tex] .

Hence, we can say that the measure of the angle XYZ will be [tex]\frac{1}{2} (154^0 -46^0 )[/tex] i.e. option C.

Following are the solution to this question:

Step-by-step explanation:

Please find the complete question and the graph in the attached file.

[tex]\to \frac{12}{l}= \frac{5.5}{l-x}\\\\\to 12(l - x) = 5.5l\\\\\to 12l - 12x = 5.5l\\\\\to 12l -5.5l = 12x\\\\\to 6.5l =12x\\\\\to 12x = 6.5l \\\\\to x = ( \frac{6.5}{12})l \\\\[/tex]

Calculating the Derivative of the above value:

[tex]\to \frac{dx}{dt} = (\frac{6.5}{12}) \frac{dl}{dt}\\\\\to \frac{dl}{dt} = (\frac{12}{6.5}) \frac{dx}{dt}\\\\\to \frac{dx}{dt} = 2 \\\\ \to \frac{dl}{dt} = ( \frac{12}{6.5} \times 2)[/tex]

Answer:

B. 5

Step-by-step explanation:

Computation for Which of the following is the resulting MAD value that can be computed from this data

Using this formula

MAD Value=[(Actual unit demand-Respective forecasts)/Number of years]

Let plug in the formula

MAD Value = [(124 - 120) + (126 - 120) + (135 - 130)]/3 years

MAD Value =(4+6+5)/3 years

MAD Value = 15/3 years

MAD Value = 5

Therefore the MAD value that can be computed from this data is 5

Answer:

67

Step-by-step explanation:

Since the diagonals in a rectangle are congruent, AC=BD and

7x+18=10x-3

We need to separate x -- to do that, we can first subtract 7x from both sides, resulting in

18=3x-3

Next, add 3 to both sides to get

21=3x

Divide both sides by 3 to get

x=7

Then, we just plug x into 10x-3 to get BD = 7*10-3 = 67
