Answer:

4y miles

Step-by-step explanation:

Max : x miles per hour

Sven: y miles per hour  slower

        x-y is the speed for Sven

We know that distance = speed * time

Distance for Max = x*t

Distance for Sven = (x-y) * t = xt - yt

The difference in distance is Max's distance minus Sven's distance

xt - ( xt-yt)

xt - xt +yt

yt

Max is yt miles ahead where t is the time

The time is noon to 4  which is 4 hours

Changing t to 4

The distance ahead is 4y miles

Answer:

47

Step-by-step explanation:

If a number x < 0, |x| = -x, in this case, x = -47, therefore |-47| = -(-47) = 47.

Answer:

26 degrees.

Step-by-step explanation:

From the figure it is clear that HI is the diameter and [tex]acr(GI)=128^{\circ}[/tex]. So,

[tex]\angle GOI=128^{\circ}[/tex]

[tex]\angle GOI+\angle GOH=180^{\circ}[/tex]          (linear pair)

[tex]128^{\circ}+\angle GOH=180^{\circ}[/tex]

[tex]\angle GOH=180^{\circ}-128^{\circ}[/tex]

[tex]\angle GOH=52^{\circ}[/tex]

Using central angle theorem of a circle, we get

[tex]\angle HIG=\dfrac{\angle GOH}{2}[/tex]

[tex]\angle HIG=\dfrac{52^{\circ}}{2}[/tex]

[tex]\angle HIG=26^{\circ}[/tex]

Therefore, the measure of angle HIG is 26 degrees.

Answer:

The speed of plane = 40 m/s

The speed of the wind = 300 m/s

Step-by-step explanation:

Let the speed of the plane = Y

And the speed of the wind = X

If the plane then travel 340 miles per hour with the wind, that means the plane and the wind are moving in the same direction. Therefore,

X + Y = 340 ..... ( 1 )

Also, 260 miles per hour against the wind. That is, the plane is moving opposite to the direction of the wind. Therefore,

X - Y = 260 ..... ( 2 )

Solve the two equations simultaneously by addition. That will eliminate Y

X + Y = 340

X - Y = 260

2X = 600

X = 600/2

X = 300 m/s

Substitutes X in equation (1)

300 + Y = 340

Make Y the subject of formula by collecting the like terms

Y = 340 - 300

Y = 40 m/s

Therefore, the speed of the plane is 40 m/s. While the speed of the wind is 300 m/s.

Answer:

The upper bound on the length of a randomly chosen nail from all nails manufactured by the company is 2.004 cm.

Step-by-step explanation:

According to the Central Limit Theorem if we have an unknown population with mean μ and standard deviation σ and appropriately huge random samples (n > 30) are selected from the population with replacement, then the distribution of the sample mean will be approximately normally distributed.  

Then, the mean of the sample means is given by,

[tex]\mu_{\bar x}=\bar x[/tex]

And the standard deviation of the sample means (also known as the standard error) is given by,

[tex]\sigma_{\bar x}=\frac{\sigma}{\sqrt{n}}[/tex]

In this case the sample of nails selected is quite large, i.e. n = 100 > 30.

So, the sampling distribution of sample mean length of nails will be approximately normal.

Then according to the Empirical rule, 95% of the normal distribution is contained in the range,

[tex]\mu\pm 2\cdot \frac{s}{\sqrt{n}}[/tex]

Compute the upper bound as follows:

[tex]\text{Upper Bound}=\mu\pm 2\cdot \frac{s}{\sqrt{n}}[/tex]

                     [tex]=2+(2\times\frac{0.002}{\sqrt{100}})\\\\=2+0.0004\\\\=2.004[/tex]

Thus, the upper bound on the length of a randomly chosen nail from all nails manufactured by the company is 2.004 cm.

Answer:

The answer you get is x=-3, and y=5 or (-3,5)

Step-by-step explanation:

3x+y=-4 and 5x-2y = -25.

Firstly,  to solve the equation let's use the multiplication method.

5x-2y=-25 (Multiply by 1)

3x+y=-4     (Multiply by 2)

=

5x-2y=-25

+6x+2y=-8

=

11x=-33

x=-3

We know that x=-3, now we can find y by substituting this value into other equations.

5(-3)-2y=-25

-15-2y=-25

+15      +15

-2y=-10

y=5

The answer you get is x=-3, and y=5 or (-3,5)

x= -3

Step-by-step explanation:

distribute and get -6x+20+4x=26

then simplify and get -2x=6

simplify again and get x=-3

Answer:

x= -3

Step-by-step explanation:

-4(1.5x-5)+4x=26

Simplify the problem:

-2x+20=26

Subtract 20 from both sides:

(-2x+20)-20=(26)-20

Simplify:

-2x=6

Divide both sides by -2

(-2x)/-2=(6)/-2

Simplify:

x=-3

Answer:

121

Step-by-step explanation:

This is an arithmetic sequence.

First term  a = -15

Common difference [d] = second term - first term

                                  = -11 - [-15] = -11 + 15 = 4

nth term = a + (n-1) * d

35th term = -15 + (35 - 1) * 4

                = -15 + 34 * 4

                = - 15 + 136

                = 121

Answer:

121 and 257

Step-by-step explanation:

So we would have our equation for arithmetic sequences which is [tex]a_{n} =a_{1} +(n-1)d[/tex] a1 is the first term, n is the term we want to know, and d is the common difference. We would plug in the numbers into the equation so we would get [tex]a_{n} =-15+(35-1)4[/tex]. And if you simplify you would get [tex]a_{n} =121[/tex].

Than for the other one we would do the same thing so you would get [tex]a_{n} = 121+(35-1)4[/tex] and if you simplify you would get [tex]a_{n} =257[/tex].

A parallelogram is a quadrilateral with two pairs of parallel sides.

Option A is the correct answer.

Parallelogram is a quadrilateral that has two pairs of parallel sides.

In a parallelogram, opposite sides and angles are equal.

The adjacent angles add up to 180 degrees.

We have,

A parallelogram is a quadrilateral with two pairs of parallel sides.

So, option A is a valid reason for the given quadrilateral to be a parallelogram.

The other options do not necessarily hold true for all parallelograms. For example, the diagonals of a parallelogram bisect each other and are congruent, but not all quadrilaterals with bisecting diagonals are parallelograms.

Similarly, not all parallelograms have congruent diagonals or congruent opposite sides.

Thus,

A parallelogram is a quadrilateral with two pairs of parallel sides.

Answer:

x=11.6

Step-by-step explanation:

According to the angle addition postulate, if B lies on AC, than AB+BC=AC.

We can use this to create this equation.

x+12+2.4=26 Where x+12 is the value of AB and 2.4 is BC.

The next step is to combine like terms, so we add 12 to 2.4 to get

x+14.4=26. When trying to find the value of a variable, you must isolate it. To do this for this equation, we must subtract 14.4 from both sides which will give you.

x=11.6

Answer:

x = 6 + 16 sqrt(3) / 3  or equivalently 6 + 16/sqrt(3)

Step-by-step explanation:

Have enough data to solve only for x in the diagram.

The lengths that make up the base are respectively from left to right

x1 = 4 cot(60) = 4 (3/sqrt(3)) = 4sqrt(3)  m

x2 = 6 m

x3 = 4 cot(30) = 4 ( sqrt(3) / 3 ) = 4/ sqrt(3) = (4/3)sqrt(3) m

Altogether

Base, x = 4sqrt(3)/3 + 6 + 2 sqrt(3)

= 6 + 16 sqrt(3) / 3  or equivalently 6 + 16/sqrt(3)

Answer:

Step-by-step explanation:

First triangle: angles are in the ratio = 30 : 60 : 90

So, the ratio of sides = a : a√3 : 2a

a√3 = 4 m

a  * 1.732 = 4

a = 4/1.732

a = 2.31

Now, in the second triangle, angles are in the ratio = 30 : 60 : 90

So, the ratio of sides = b : b√3 : 2b

b = 4 m

b√3 = 4 * 1.732 = 6.928 m

x = a + 6 + b

x = 2.31 + 6 + 6.928

x = 15.23 m
