Answer:

Let x = speed for the first 96 miles

x - 9 = speed for the last 100 miles

Distance = (rate)(time), so time = (distance)/(rate)

(time for first part of trip) + (time for last part of trip) = 4 hours

So, (96)/(x) + (100)/(x - 9) = 4

Multiply both sides by the LCD (x)(x - 9) to get

96(x - 9) + 100x = 4x(x - 9)

96x - 864 +100x = 4x2 - 36x

4x2 - 232x + 864 = 0

Divide both sides by 4 to obtain x2 - 58x +216 = 0

(x - 4)(x - 54) = 0

x = 4 or x = 54

Note that x can't equal 4 because, in that case, x - 9 would be negative, so x = 54 miles per hour.

Answer:

Y=mx+c

Step-by-step explanation:

The number in front of the x is the gradient. This shows how much the line goes up in the y axis for every square in the x axis. The number after the plus is the y intersect. This is where the line crosses the y axis. Start at the y intersect and draw the line. For this question, the gradient is 2, so the line goes up 2 squares on the y axis for every square on the x axis. The y intersect is 1, so it would cross the y axis at +1 on the y axis

Answer: the final answer is 1 4/5 or 9/5

Step-by-step explanation:

First:

Convert any mixed numbers to fractions.

Then your initial equation becomes:

3 3/4 turns into 15/4 and 2 1/12 turns into 25/12

Second: then flip the 2nd fraction so it becomes 12/25

now multiply straight across: 15/4 x 12/25

15 x 12=180

4 x 25=100

180/100= 9/5= 1 1/4

Simplest form of quotient of given fractions is 9/5.

The given fractions are [tex]3\frac{3}{4}[/tex] and [tex]2\frac{1}{12}[/tex].

Dividing two fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. The first step to dividing fractions is to find the reciprocal of the second fraction. Next, multiply the two numerators. Then, multiply the two denominators.

[tex]3\frac{3}{4}[/tex] can be written as [tex]\frac{15}{4}[/tex] and [tex]2\frac{1}{12}[/tex] can be written as [tex]\frac{25}{12}[/tex].

Keep 15/4 and change division sign to multiplication sign and reverse the fraction 25/12 as 12/25.

That is , [tex]\frac{15}{4} \div \frac{25}{12} = \frac{15}{4} \times \frac{12}{25}[/tex]

[tex]=\frac{3}{1} \times \frac{3}{5} =\frac{9}{5}[/tex]

So, quotient = 9/5

Therefore, simplest form of quotient of given fractions is 9/5.

Answer: [tex]\sqrt{11[/tex]

Step-by-step explanation: pythagorean theorem a^2 + b^2 =c^2

switch it to c^2 - b^2 = a^2

c=6 and b=5

[tex]\sf\longmapsto \: x = 8 \: gallons[/tex]

[tex]\sf\longmapsto \: x = \: 8 \times \frac{3}{8} : 6[/tex]

[tex]\sf\longmapsto \: \frac{3}{6} \: gallons[/tex]

Therefore,It should be sufficient as 9/16 is more than 1/2

Answer:

43°

(4x + 19)° = (6x + 7)° [vertically opposite angles are equal]

4x+19 = 6x+7

4x + 19 -7 = 6x

4x +12 = 6x

12 = 6x - 4x

12 = 2x

2x = 12

x = 12/2

x = 6

Now replace the x with 6

(4x+19)°

= (4×6+19)°

= (24+19)°

= 43°

(6x+7)°

= (6×6+7)°

= (36+7)°

= 43°

The measure of the angles is 43 degrees

Answer:^3−28

Step-by-step explanation:

The image of the point (8, 6) dilated by a scale factor 1/2 is (4, 3)

The given point is (8, 6)

The scale factor of dilation = 1/2

To dilate a given point (x, y) by a scale factor m, multiply each of the coordinates (x, y) by m

The image = (mx, my)

For the point (8, 6) dilated by 1/2, the image will be calculated as shown below:

[tex](\frac{1}{2}\times 8, \frac{1}{2} \times 6)\\= (4, 3)[/tex]
