Answer:
x = 17
Step-by-step explanation:
(6x - 20) and the angle vertically opposite (6x - 4) are same- side interior angles and sum to 180° , that is
6x - 20 + 6x - 4 = 180
12x - 24 = 180 ( add 24 to both sides )
12x = 204 ( divide both sides by 12 )
x = 17
A mint milk shake contains 1.25 fluid ounces of milk for every 4 ounces of ice cream. A strawberry milk shake contains 1.75 fluid ounces of milk for every 5 ounces of ice cream. Which milk shake is thicker? Explain.?
Answers
Both milkshakes have the same thickness.
How to find the thickness of milk?
Given,
A mint milkshake contains 1.25 fluid ounces of milk for every 4 ounces of ice cream.A strawberry milkshake contains 1.75 fluid ounces of milk for every 5 ounces of ice cream.Solution:
Since the mint milkshake contains 1.25 fluid ounces of milk for every 4 ounces of ice cream,One ounce ice equal = 1.25 / 4 = 0.35 ounce of milk.Since the strawberry milkshake contains 1.75 fluid ounces of milk for every 5 ounces of ice cream,One ounce of ice equal = 1.75 / 5 = 0.35ounce of milk.Since both have an equal milk-ice ratio, both milkshakes have the same thickness.To learn more about ratios, refer

At an after-season sale on winter clothes, I found a bunch of really cute hats and scarves. I decided to buy two hats and two scarves for myself to have for next year. I spent $72. When I told my friends about the sale, they asked me to go back and get something for them. I ended up spending $46 on one hat and two scarves. What was the price of a single hat and a single scarf?Write two integers separated by comma, no spaces, no dollar sign
Answers
ANSWER
One hat costs $26 and one scarf costs $10
EXPLANATION
Let the price of one hat be h.
Let the price of one scarf be s.
Two hats and two scarves cost $72. This implies that:
[tex]2h+2s=72[/tex]One hat and two scarves cost $46. This implies that:
[tex]h+2s=46[/tex]From the second equation, make h the subject of the formula:
[tex]h=46-2s[/tex]Substitute that into the first equation and solve for s:
[tex]\begin{gathered} 2(46-2s)+2s=72 \\ 92-4s+2s=72 \\ \Rightarrow92-72=4s-2s \\ 2s=20 \\ \Rightarrow s=\frac{20}{2} \\ s=\$10 \end{gathered}[/tex]Substitute the value of s into the equation for h and solve for h:
[tex]\begin{gathered} h=46-2(10) \\ h=46-20 \\ h=\$26 \end{gathered}[/tex]Hence, one hat costs $26 and one scarf costs $10.

1) the initial expression is:
[tex]2x^2+5x-12[/tex]To factor this expression we can use the cuadratic formula that is:
[tex]\begin{gathered} x=\frac{-b\pm\sqrt[]{b^2-4(a)(c)}}{2(a)} \\ a=2 \\ b=5 \\ c=-12 \end{gathered}[/tex]so we replace the values and we get:
[tex]\begin{gathered} x=\frac{-5\pm\sqrt[]{5^2-4(2)(-12)}}{2\cdot2} \\ x=\frac{-5\pm\sqrt[]{121}}{4} \\ x=\frac{-5\pm11}{4} \end{gathered}[/tex]So now we have two solutions so:
[tex]\begin{gathered} x_1=\frac{-5+11}{4}=\frac{6}{4}=\frac{3}{2}=1.5 \\ x_2=\frac{-5-11}{4}=-\frac{16}{4}=-4 \end{gathered}[/tex]so the factor expression will be:
[tex](x-\frac{3}{2})(x+4)[/tex]2) the initial expression is:

4)PQRS is a rectangle. The length of the diagonal PR is 10cm. If PQ = 8cm, find the perimeter of the
rectangle.
Answers
The perimeter of the rectangle PQRS would be 28 cm which is the addition of all lengths of sides.
The given rectangle PQRS that has a length of the diagonal PR is 10 cm and PQ = 8 cm
What is the perimeter of the rectangle?The perimeter of a rectangle is defined as the addition of the lengths of the rectangle's four sides.
To determine the perimeter of the rectangle.
Since opposite sides of the rectangle and diagonal are equal.
⇒ PQ = SR = 8 cm
⇒ PR = QS = 10 cm
⇒ PS = QR = x cm (suppose)
In the rectangle, all the angles are right angles
Now in △QRS,
Using Pythagoras' theorem, we have
QS² = QR² + SR²
10² = x² + 8²
x² = 100 - 64
x =√36
x = 6 cm
So length of PS = QR = 6 cm
The perimeter of the rectangle = PQ + SR + PS + QR
The perimeter of the rectangle = 8 + 8 + 6 + 6 = 28 cm
Therefore, the perimeter of the rectangle PQRS would be 28 cm.

To answer this question, we need to remember that the slope-intercept form of the line is given by:
[tex]y=mx+b[/tex]Where
• m is the slope of line
,• b is the y-intercept of the line, that is, the point where the line passes through the y-axis. At this point, x = 0.
Since we can see that the given equation is in slope-intercept form:

If they are paving a rectangular area and an area in the shape of a parallelogram to make it easier to turn around and pull out of the driveway. A sketch of the plan for their driveway uses a scale of 1 in. for every 3 ft. The actual area of the entire driveway they want to pave Is 1350 feet²
Actual areaFirst step is to find the length of both side
Actual length on side
Length = ( 5 + 4) × 3
Length = 9 × 3
Length = 27 feet
Actual length of the other side
Length = 16 2/3 × 3
Length = 16 ×3 +2/3 ×3
Length = 16×3+2
Length = 48 +2
Length = 50 feet

Two friends drive off in different directions from the same place. one heads north at 25 miles per hour, while the other heads east at 40 miles per hour. complete an equation for the distance between the friends after t hours.
Answers
Answer: [tex]5t\sqrt{89}[/tex] miles
=======================================================
Explanation:
Draw a right triangle. The legs of this triangle represent the directions the two friends travel (one going east, the other going north).
The horizontal leg has side length 40t and the vertical leg has length 25t, where t is the number of hours.
I'm using the idea that distance = rate*time.
We'll use the pythagorean theorem to find the hypotenuse in terms of t.
[tex]a = 40t, \ b = 25t\\\\a^2 + b^2 = c^2\\\\c = \sqrt{a^2+b^2}\\\\c = \sqrt{(40t)^2+(25t)^2}\\\\c = \sqrt{1600t^2+625t^2}\\\\c = \sqrt{2225t^2}\\\\c = \sqrt{25*89t^2}\\\\c = \sqrt{25t^2}*\sqrt{89}\\\\c = 5t\sqrt{89}\\\\[/tex]
At time t hours, the distance between the two friends is exactly [tex]5t\sqrt{89}[/tex] miles.

Suppose a normal distribution has a mean of 18 abd a standard deviation of 4. A value of 24 is how many standard deviations away from the mean
Answers
Normal Distribution
The normal distribution can be described by two parameters: the mean and the standard deviation.
We are given the parameters of a normal distribution as follows:
Mean = 18
SD = 4
A value of 24 is 24 - 18 = 6 units away from the center of the distribution, or the mean value.
Calculating the ratio of 6 units by 4 units, we get 6 / 4 = 1.5
This means the given value is 1.5 standard deviations away from the mean
