A car travels 104 kilometers in 2 hours. What is its speed?

Answer:

The measure of Angle S is 75 (degrees).

Step-by-step explanation:

Key skills needed to solve this are: Sums of a triangle, one variable equation, operations

1) All the angles in a triangle add up to equal 180 degrees.

2) We can use this to say that Angle S + Angle R + Angle T is 180 degrees.

3) Subsitute in the expression for each angle: 7x+40+8x+25+5x+15 = 180

4) Combine like terms

7x + 8x + 5x is 20x & 40 + 25 + 15 is 80

This means that 20x + 80 = 180

5) Move 80 to the right side: 20x = 100

6) Divide by 20 andbget x equal to 5

7) To find Angle S, you need to plug in 5 into the expression.

7x + 40 = 7(5) + 40 = 35 + 40 = 75 degrees

The measure of Angle S is 75

Answer:

B , C, and D

Step-by-step explanation:

x + y and x+ z both make a straight line which is 180 degrees, and Z and Y are congruent angles.

Answer:

x=-3

Step-by-step explanation:

First you must distribute -5 to 2x and -7

so you get

-10x+35+24=89

then you will subtract 35 from both sides and get

-10x+24=54 then you will subtract 24 from each side and get

-10x=30 then you will divide -10 and get

x=-3

Step-by-step explanation:

detrain of the value they was given

Answer:

Length = 37 feet

width = 11 feet

Step-by-step explanation:

First, let us find the value of x.

They've already given that the perimeter of this rectangle is 96 feet.

So,

4x - 7 + 4x - 7 + x + x = 96

10x - 14 = 96

10x = 96 + 14

10x = 110

Divide both sides by x.

x = 11 feet

And now we can find the value of the width and length.

Given that,

Length = ( 4x - 7 ) ⇒ ( 4 × 11 - 7 )

                                  44 - 7

                                    37 feet

Width = x ⇒ 11 feet

Answer:

  w = 2.3

Step-by-step explanation:

It looks like you have ...

  4.6/6 = w/3

To solve this, you need to clear the 3 from the denominator of the w term. Do that by multiplying both sides of the equation by 3.

  3(4.6/6) = 3(w/3)

  4.6(3/6) = w . . . . simplify (rearrange the product to make mental arithmetic easier: 3/6 = 1/2)

  w = 2.3 . . . . . . . . do the arithmetic

The standard error is 1.91.

For a data set the standard error is calculated by the ratio of standard deviation and square root of the sample size.

[tex]\rm Standard \; Error= \dfrac{ \sigma}{\sqrt{n}}[/tex]

Substituting the values

Standard Deviation = 25.29

Sample size = 175

Standard Error = 25.29 / √175

Standard Error = 1.91

[tex]169^{5} = (13^{2})^5 = 13^{10}[/tex]

The square root of [tex]13^{10}[/tex] is given by:

Answer:

2/3

Step-by-step explanation:

Given:

Number of eclairs = 3

Number of humbugs =2x+6=2(x+3)  

Number of mints =  x

Therefore, total number of sweets in the jar is,

s=3+2x+6+x=3x+9=3(x+3)

Now, probability of selecting a sweet to be humbug is given as:

 p(humbug)= number of humbugs/number of sweets

p(humbug)=2(x+3)/3(x+3)=2/3

Therefore, the probability that it is a humbug is 2/3

The pattern of the addend is that the first term increases by 1/8 and the second term is always 1/4. If only the first term increases by 1/8, that means the total sum will increase by 1/8 each time also.

Answer:

Answer: Choice G.

Step-by-step explanation:

Dilations

Suppose a point P(x,y) is dilated across the origin, that is, the origin is the center of dilation, by a scale factor k.

The image of P is P' whose coordinates are P'(kx,ky).

If an image is formed by several points and each one is dilated by the same factor, then:

If |k| > 1, the image maps to a stretched or larger image.

If |k| < 1, the image maps to a shrunk or shorter image.

We have a hexagon graphed on a coordinate grid. The hexagon is dilated to create a larger hexagon. This means k must be greater than 1 and it should multiply each original coordinate (x,y).

Options F and H don't multiply by the coordinates but add to them, thus they are not valid answers.

Option J actually multiplies by the factor 0.2 but since it's less than 1, it does not correspond to an enlargement.

Only option G multiplies by a factor 4/3=1.3 greater than 1.

y intercept = 3

[tex]m = \frac{1}{3}[/tex] --- slope

Step-by-step explanation:

Given

The attached graph

Required

Determine the slope and the y intercept

The [tex]y\ intercept[/tex] is at the point where [tex]x = 0[/tex].

From the graph:

[tex]y = 3;\ when\ x = 0[/tex]

Hence,

y intercept = 3

Next, we calculate the slope using:

[tex]m = \frac{y_1 - y_2}{x_1 - x_2}[/tex]

Where:

[tex](x_1,y_1) = (0,3)[/tex]

[tex](x_2,y_2) = (9,6)[/tex]

So, we have:

[tex]m = \frac{3 - 6}{0 - 9}[/tex]

[tex]m = \frac{-3}{- 9}[/tex]

[tex]m = \frac{3}{9}[/tex]

[tex]m = \frac{1}{3}[/tex]

Equation of Sphere =  [tex]x^{2}[/tex] + [tex]y^{2}[/tex] + [tex]z^{2}[/tex] - 18x - 4/3y +10z + 142/3 = 0

Step-by-step explanation:

Data Given:

P = (x,y,z)

Distance from P to A (-3,6,3) = Twice the distance from P to B(6,2,-3)

Solution:

Find the equation of the sphere:

It is given that:

PA = 2PB

Squaring both sides:

[tex](PA)^{2} = (2PB)^{2}[/tex]

[tex](PA)^{2} = 4 (PB)^{2}[/tex]

[tex](x - (-3))^{2}[/tex] + [tex](y - 6)^{2}[/tex] + [tex](z-3)^{2}[/tex] = 4 x [tex](x-6)^{2}[/tex] + [tex](y-2)^{2}[/tex] + [tex](z-(-3))^{2}[/tex]

Solving the above equation:

[tex](x + 3))^{2}[/tex] + [tex](y - 6)^{2}[/tex] + [tex](z-3)^{2}[/tex] = 4 x {[tex](x-6)^{2}[/tex] + [tex](y-2)^{2}[/tex] + [tex](z + 3))^{2}[/tex]}

[tex]x^{2}[/tex] + 9 + 6x + [tex]y^{2}[/tex] + 36 - 12y + [tex]z^{2}[/tex] + 9 - 6z = 4 { [tex]x^{2}[/tex] + 36 - 12x + [tex]y^{2}[/tex] + 4 - 4y + [tex]z^{2}[/tex] + 9 + 6z}

[tex]x^{2}[/tex] + 9 + 6x + [tex]y^{2}[/tex] + 36 - 12y + [tex]z^{2}[/tex] + 9 - 6z = 4[tex]x^{2}[/tex] + 144 - 48x +4[tex]y^{2}[/tex] + 16 - 16y + 4[tex]z^{2}[/tex] + 36 + 24z

Putting the right hand side = 0 and solving the equation:

[tex]x^{2}[/tex] - 4[tex]x^{2}[/tex] + [tex]y^{2}[/tex] - 4[tex]y^{2}[/tex] + [tex]z^{2}[/tex] - 4[tex]z^{2}[/tex] + 6x + 48x - 12y +16y -6z - 24z + 9 + 36 + 9 -144 - 16 - 36 = 0

-3[tex]x^{2}[/tex] - 3[tex]y^{2}[/tex]  -3[tex]z^{2}[/tex]  + 54x + 4y -30z -142  = 0

Taking (-) common

- ( 3[tex]x^{2}[/tex] + 3[tex]y^{2}[/tex] + 3[tex]z^{2}[/tex]  - 54x - 4y +30z + 142) = 0

3[tex]x^{2}[/tex] + 3[tex]y^{2}[/tex] + 3[tex]z^{2}[/tex]  - 54x - 4y +30z + 142 = 0

dividing the whole equation by 3

[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + [tex]z^{2}[/tex] - 54/3x - 4/3y +30/3z + 142/3 = 0

[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + [tex]z^{2}[/tex] - 54/3x - 4/3y +30/3z + 142/3 = 0

[tex]x^{2}[/tex] + [tex]y^{2}[/tex] + [tex]z^{2}[/tex] - 18x - 4/3y +10z + 142/3 = 0

The equation of the sphere for all surface point P such that [tex]AP = 2\cdot BP[/tex] is [tex]x^{2}+y^{2}+z^{2}-18\cdot x -\frac{4}{3}\cdot y + 10\cdot z +\frac{142}{3} = 0[/tex].

Mathematically speaking, we have the following geometric locus:

[tex]AP = 2\cdot BP[/tex] (1)

Then, we expand the expression presented above by Pythagorean theorem, used to determine the length of a line segment in the field of analytical geometry:

[tex]\sqrt{(x +3)^{2} + (y-6)^{2} + (z-3)^{2}} = 2\cdot \sqrt{(x-6)^{2}+(y-2)^{2}+(z+3)^{2}}[/tex]

[tex](x+3)^{2}+(y-6)^{2}+(z-3)^{2} = 4\cdot (x-6)^{2}+4\cdot (y-2)^{2}+4\cdot (z+3)^{2}[/tex]

Now we expand and simplify the resulting expression:

[tex]x^{2}+6\cdot x + 9 + y^{2}-12\cdot y + 36 + z^{2}-6\cdot z + 9 = 4\cdot (x^{2}-12\cdot x +36) + 4\cdot (y^{2}-4\cdot y +4) + 4\cdot (z^{2}+6\cdot z + 9)[/tex]

[tex]x^{2} + y^{2} + z^{2} + 6\cdot x -12\cdot y - 6\cdot z +54 = 4\cdot x^{2} +4\cdot y^{2} + 4\cdot z^{2} -48\cdot x -16\cdot y +24\cdot z +196[/tex]

[tex]3\cdot x^{2} + 3\cdot y^{2} + 3\cdot z^{2} -54\cdot x -4\cdot y + 30\cdot z + 142 = 0[/tex]

[tex]x^{2}+y^{2}+z^{2}-18\cdot x -\frac{4}{3}\cdot y + 10\cdot z +\frac{142}{3} = 0[/tex] (2)

This expression corresponds to the general form of the equation of the sphere for all surface point P such that [tex]AP = 2\cdot BP[/tex]. [tex]\blacksquare[/tex]

Answer:

6/7

Step-by-step explanation:

1 x 7/6 x 6/7 = 1

A scale factor of 6/7 would shrink the dilated figure back to its original size.

To return the dilated figure back to its original size, you would need to use a scale factor that is the reciprocal of the original dilation scale factor. The reciprocal of a fraction is obtained by flipping the numerator and denominator.

Given the original dilation scale factor of 7/6, the scale factor that would shrink the dilated figure back to the original size is:

Reciprocal of 7/6 = (6/7)

So, using a scale factor of 6/7 would shrink the dilated figure back to its original size.
