a person walking along a straight road observes that at two consecutive kilometer stones, the angles of elevation of a hill in front of him are 30degree and 45 degree find the height of the hill

Answers

First, you need to draw the situation: you have three points on a straight line, A is the first kilometer stone, B is the second one and C is the foot of the hill. Let's call H the top of the hill. Connecting H with both A and B you get two triangles rectangle (BCH and ACH).

The triangle rectangle BCH has one other angle that is 45°, which means that it is an isosceles triangle, therefore BC = HC = height of the hill (h).

Now, consider the triangle ACH: it has an angle of 30° (which means that the other angle is 60°) and AC = BC + AB = h + 1 (where we considered h measured in km).
In such a particular triangle (30°- 60°- 90°), the ratio between the long and the short leg is √3, which means that:
√3·HC = AC

We can then write:
√3·h = (h + 1)

which can be solve for h:
√3·h - h = 1
h(√3 - 1) = 1
h =1/ (√3 - 1) 

We can rationalize:
h =  [tex] \frac{1}{ \sqrt{3} - 1} \frac{ \sqrt{3} + 1}{ \sqrt{3} + 1 } [/tex]
   = (√3 + 1) / 2
   = 1.366 km

Therefore the correct answer is: the hill is 1.366km high

In parallelogram ABCD, m∠A = 24°. What are the measures of angles B, C, and D? Justify. please help

Answers

parallelogram has 2 pairs of angles as well as a sum angle of 360
therefore, another angle is also 24°and the other two are 360-24*2=312. 312/2=156

four angles are 24,24,156,156
The sum of the angles in a parallelogram is 360°. 

a+b+c+d=360°

The opposite angles in the parallelogram are congruent.

a=c

b=d

So if a=24°... and we know a=c, then c=24°.

a=24

c=24

b=?

d=?

a+b+c+d=360°
plug in the data we know
24+b+24+d=360
48+b+d=360
b+d=312

If b+d=312, and we know that they are congruent, then to find their values just divide 312 by 2

312/2=156°

b=156°

d=156°

6x - 4x + 1 = 2 + x + 4

2x + 1 = x + 6

subtract x from both sides to move x to one side

x + 1 = 6

subtract 1 from both sides to isolate the x

x + 1 (-1) = 6 (-1)

x = 6 - 1

Answers

Total cost of job=$231.08
Labor time= 6 1/2 = 6.5 hours
Overhead=55%
Retail price of parts=$114.70
Find the total cost of labor.
Total cost of labor= 231.08 - 114.70=$116.38
Now labor rate per hour ( with overhead)= 116.38 /6.5 =$17.90 per hour.

Use the parabola tool to graph the quadratic function f(x)=−12x2+7. Graph the parabola by first plotting its vertex and then plotting a second point on the parabola.

Answers

First we find the vertex of parabola [tex]f(x)=-12 x^{2} +7[/tex]

The vertex of parabola is [tex]( \frac{-b}{2a},f( \frac{-b}{2a})) [/tex]
Here,
b = coefficient of x term
a = coefficient of x² term

For given parabola, b = 0 , a = -12

So,
[tex] \frac{-b}{2a}= \frac{0}{-24} =0 [/tex]

And,

[tex]f( \frac{-b}{2a} )=f(0) = -12(0)+7=7[/tex]

Thus the vertex of parabola is (0, 7)

To find another point on parabola, substitute x by 1.

[tex]f(1)=-12( 1^{2}) +7=-12+7=-5[/tex]

So the second point on parabola is (1,-5)

The perimeter of a rectangular banner is 72 inches. The width of the banner is 1/3 its length. What is the area of the banner? The first one with a good answer will be count as the brainlist. Please help

Answers

To find the area you will need to begin with the information about the perimeter.  You will use the formula P = 2l + 2w.  You will replace what we know in this formula making it 72 = 2l + 2 (1/3l).  You will replace the width with the information we know about the width.  Simplify the expression on the right to make a new equation 72 = 2 2/3 l.  Solve for the length by dividing both sides by 2 2/3.  When you divide 72 by 2 2/3 you get 27 inches as your answer.  This is the length.  Once you know the length, you can take 1/3 of it (1/3 x 27) to get the width of 9 in.  Now that you know the length and the width, you will multiply these together (27 in. x 9 in) to get an area of 243 square inches!

Final answer:

To find the area of the banner with a given perimeter of 72 inches and a width that is 1/3 its length, we first determine the length to be 27 inches and the width to be 9 inches, leading to an area of 243 square inches.

Explanation:

To solve the problem, let's denote the length of the rectangular banner as L inches and the width as W inches. We're given that the perimeter is 72 inches and that the width is 1/3 its length, hence W = 1/3 * L. The formula for the perimeter of a rectangle is 2L + 2W = 72.

Substituting the value of W in terms of L into the perimeter equation gives 2L + 2(1/3 * L) = 72. Simplifying this equation: 2L + 2/3L = 72, or (6/3)L + (2/3)L = 72, which simplifies to (8/3)L = 72. By solving this equation, we find that L = 27 inches. Therefore, W = 1/3 * 27 = 9 inches.

Finally, the area of the rectangle, which is Length × Width, can now be calculated as 27 inches × 9 inches = 243 square inches.

1st equation: 5x + 60y =35

2nd equation: x + y = 1.5 r
3rd equation: rewrite 2nd equation as : x =1.5-y)

replace x in first equation with 3rd equation:

5(1.5-y) + 60y = 35

 now solve for y:
7.5 - 5y + 60y = 35
7.5 + 55y = 35
55y = 27.5
y = 27.5 / 55 = 0.5
 

now replace Y with 0.5 in the 2nd equation and solve for x

x +0.5 = 1.5

x = 1.5-0.5
x = 1

5x = 5(1) = 5 miles walked

5X + 60Y = 35
X + Y = 1.5
Ok so this is known as a system of equations. The x variable in the first equation is the same as the x in the second equation, as is the y.
So in order to solve this, let's solve for one of the variables in the second equation. It doesn't matter which so lets just pick the variable y.
So
X + Y = 1.5
Subtract X from both sides
Y = -X + 1.5
Voila! You have a variable for y. Now you can substitute you value of y into the other equation.
5X + 60(-X + 1.5) = 35
Now do you see how we only have one variable to solve for in the equation? Solve this equation and you have the value of x.
5X - 60X + 90 = 35
-55X = -55
X = 1
Hah! We have a value for X! But what is the value of y? In ordering to find the value of y you need to take a previous equation and substitute the value that we found for x into the equation. Let's take the easiest equation shall we?
X + Y = 1.5
X = 1
1 + Y = 1.5
Y = 0.5

~kaikers
Lets get started :)

We can use the concept of ratios 

5g of margarine : 3.6g fats
92g of margarine : ?

We can cross multiply, which is an easier solution

Let us use the variable p to represent the grams of fats to be found

5 x p = 3.6 x 92
5p = 331.2

We, now, can divide by 5 on either sides so we can isolate and find the value of p

[tex] \frac{5p}{5} = \frac{331.2}{5} [/tex]
5 and 5 cancels out

p = 66.24

So, 92g of margarine will contain 66.24g of fats

In a bag of marbles, 12% were red, 14% were blue, and the rest were white. If the bag has 250 marbles, how many were red or blue

Answers

30 red, 35 blue, and 185 white. your welcome. please mark me as brainliest
Hello!

We've been given enough information to solve this question! We know that there are a total of 250 marbles in the bag, and that 12% are blue and 14% are red, and the rest are white.

To calculate how many marbles are red and blue, we must first convert the percentages to decimals by dividing them by 100, and then we'll multiply the decimals by 250 marbles.

I know, that's probably a lot to take in! :D

12% ÷ 100 = 0.12

0.12 × 250 = 30

This means that 30 marbles were red.

14% ÷ 100 = 0.14

0.14 × 250 = 35

This means that 35 marbles were blue.

Final Answer:

30 marbles were red, 35 marbles were blue, and the rest were white.

a baseball coach uses a pitching machine to simulate pop flies during practice. the quadratic function f(x)=-16x^2+70x+10 models the height in feet of a baseball after x seconds. how long is the baseball in the air if the ball is not caught?

Answers

Final answer:

Using the quadratic equation f(x) = -16[tex]x^2[/tex] + 70x + 10, which models the height of the baseball, we apply the quadratic formula to find that the ball is in the air for approximately 4.438 seconds before it lands back on the ground if not caught.

Explanation:

The student asks how long a baseball remains in the air during practice using a quadratic equation that models the height of the baseball after a certain number of seconds. The equation provided is f(x) = -16[tex]x^2[/tex] + 70x + 10, which models the height in feet of the baseball after x seconds. To determine the time the baseball is in the air, we need to find when the ball returns to the ground level (when f(x) = 0).

We can solve this quadratic equation using the quadratic formula: x = (-b ± [tex]\sqrt{(b^2 - 4ac)) / (2a)}[/tex], where a is -16, b is 70, and c is 10. Plugging in these values, we get two solutions for t (time), and we choose the positive time value at which the height becomes zero again, indicating that the ball has landed back on the ground.

The use of the quadratic formula yields t = 4.438 seconds and t = -0.138 seconds. We discard the negative time value as it is not physically relevant to the problem, and thus the baseball is in the air for approximately 4.438 seconds before it lands back on the ground if it's not caught.

A bicyclist started on his trip from city A to city B. In 1 hour and 36 minutes, a biker also left A and headed towards B, and he arrived there at the same time as the bicyclist. Find the speed of the bicyclist if it is less than the speed of the biker by 32 km/hour, and the distance between the two cities is 52 km.

Answers

Speed of first bicyclist=x
Speed of  biker= x+32
Convert 1 hour and 36 min to hours.
1+36/60 = 1.6 hours
Bicyclist time is 1.6 hours longer than biker.
Equation is:
52/x - 1.6 = 52/(x+32)
Solve for x.
52(x+32)-1.6(x+32)=52x
5x+1664-1.6x²-51.2x=52x
Simplify
1.6x²+51.2x-1664=0

For the figures shown, HJKL ~ QRST . The scale factor applied to HJKL to create QRST is 8 to 7. What is RS? A. 74 B. 72 C. 64 D. 49

Answers

The length of RS is 64 units. Therefore, the correct answer is C. 64.

Since HJKL is similar to QRST, corresponding sides of the two figures are proportional.

Given that the scale factor applied to HJKL to create QRST is 8 to 7, this means that the ratio of corresponding sides of HJKL to QRST is 8:7.

Let's denote the length of RS as x.

According to the scale factor, the ratio of corresponding sides RS and HJ is 8:7. So, we can set up the following proportion:

[tex]\[\frac{RS}{HJ} = \frac{8}{7}\][/tex]

Given that HJ is 56 units (since 8 times the length of HJ), we can solve for RS:

[tex]\[x = \frac{8}{7} \times 56\][/tex]

[tex]\[x = \frac{448}{7}\][/tex]

[tex]\[x = 64\][/tex]

Therefore, RS is 64 units.

So, the correct answer is C. 64.
