Mary is standing out on the balcony of her apartment which is 40 feet above the ground and looks up at a 31° angle to see her friend Sue who is standing on her balcony. If Mary and Sue's apartments are 20 feet apart from one another, how high off the ground is Sue?

Answers

Answer:

52 feet

Step-by-step explanation:

This situation can be represented by the attached figure as in the answer area.

Let M be the location of Mary.

Let S be the location of Sue.

Distance between apartments is given as 20 feet.

Distance between ground and balcony of Mary is 40 feet.

There is a right angled [tex]\triangle MOS[/tex].

[tex]\angle OMS = 31^\circ[/tex]

To find:

The distance SO + 40 feet.

We can use tangent ratio here in right angled [tex]\triangle MOS[/tex].

[tex]tan\theta = \dfrac{Perpendicular}{Base}[/tex]

[tex]tan31^\circ = \dfrac{SO}{MO}\\\Rightarrow tan31^\circ = \dfrac{SO}{20}\\\Rightarrow SO=20\times 0.6\\\Rightarrow \bold{SO=12\ ft}[/tex]

Height of Sue above ground = 40+12 = 52 feet

The second picture represents the addition of two vectors u and v by the parallelogram method for vector addition.

What is a vector?

It is defined as the quantity that has magnitude as well as direction also the vector always follows the sum triangle law.

We have:

Two vectors u and v

The resultant vector will be u + v

As we know, in the parallelogram method for vector addition

We have to place two vectors at the same starting point.

Then complete the parallelogram.

The diagonal of the parallelogram represents the addition of the vector.

Thus, the second picture represents the addition of two vectors u and v by the parallelogram method for vector addition.

The area of the base of a rectangular prism is 24 square centimeters and the height is 12 centimeters. What is the volume of the rectangular prism in cubic centimeters?

Answers

Answer:

V = 288 cm³

Step-by-step explanation:

Given that,

The area of the base of a rectangular prism is 24 square centimeters and the height is 12 centimeters.

We need to find the volume of the rectangular prism. For a rectangular prism, the volume is given by :

V = lbh

Since, lb = A, area of the prism

V = Ah

V = 24 × 12

= 288 cm³

So, the volume of the rectangular prism is 288 cm³.

What is the value of this expression when a=3 and b= -2? (3a (exponent) -2 b (exponent) 6) exp. -2 ___________________________ (2a (exponent) -1 b (exponent) 5) Its all one equation!

Answers

Answer:

I looked online to find the equation well written, but i could not find it, so i will guess that the equation is:

[tex]\frac{3*a^{-2} - 2*b^{-6}*e^{-2}}{2*a^{-1}*b^{5}}[/tex]

Now we want to find the value of this equation when:

a = 3 and b = -2

So we can just replace these values in the equation, each a is replaced by a 3, and each b is replaced by a -2.

The equation becomes.

[tex]\frac{3*3^{-2} - 2*(-2)^{-6}*e^{-2}}{2*3^{-1}*(-2)^{5}} = 44.3[/tex]

1) "teacher" wants to build a rectangular dog bowl stand. The top of it will have a perimeter 55 1/2 inches. The length is twice as long as the width. What are the dimensions (length and width) of the top of the dog bowl stand? (Note: Your answer should be in fraction form, not a decimal.) 2) During their basketball game, "teacher 1" shoots twice as many airballs as "teacher 2". "teacher 3" shoots 4 airballs less than "teacher 2". If they shot 24 airballs together, how many airballs did each teacher shoot?

Answers

Answer:

1)

[tex]L=18 \frac{1}{2} in[/tex]

[tex] W= 9 \frac{1}{4} in[/tex]

2)

[tex]T_{1}=14 balls[/tex]

[tex]T_{2}=7 balls[/tex]

[tex]T_{3}=3 balls[/tex]

Step-by-step explanation:

In order to solve this problem, we need to build the equations we need. Since there are two values we want to figure out (length and width) we will then need two equations to solve simultaneously.

First, the problem tells us that the perimeter is 55 1/2 in, which can be rewritten as an improper fraction:

[tex]55 \frac{1}{2}= \frac{55*2+1}{2}= \frac{111}{2}[/tex]

Next, we also know the perimeter of a rectangle is found by using the following formula:

P=2L+2W

where L is the length of the rectangle and W is its width.

So our first equation will look like this:

[tex]2L+2W=\frac{111}{2}[/tex]

Next, the problem tells us that the width of the rectangle is twice its width, so our second equation will look like this:

L=2W

which can be substituted into our first equation:

[tex]2L+L=\frac{111}{2}[/tex]

Now, we can solve this for L, so we get:

[tex]3L=\frac{111}{2}[/tex]

[tex]L=\frac{111}{2*3}[/tex]

[tex]L=\frac{111}{6}=18 \frac{3}{6}=18 \frac{1}{2}[/tex]

so we can now use this information to find its width:

L=2W

[tex] \frac{111}{6}=2W[/tex]

so

[tex]W=\frac{111}{6*2}[/tex]

[tex]W=\frac{111}{12}=9\frac{3}{12}=9\frac{1}{4}[/tex]

2)

When solving this problem it is a good idea to split it into little chunks of information. The first sentence says:

"... "teacher 1" shoots twice as many airballs as "teacher 2"."

This can be translated as an equation like this:

[tex]T_{1}=2T_{2}[/tex]

The next sentence says:

""teacher 3" shoots 4 airballs less than "teacher 2"."

This can be written as an equation like this:

[tex]T_{3}=T_{2}-4[/tex]

and finally, the problem states: "... they shot 24 airballs together,..."

This can be written as an equation like this:

[tex]T_{1}+T_{2}+T_{3}=24[/tex]

so now we can do substitutions. We can take the first and second equations and write them into the third equation so we get:

[tex]2T_{2}+T_{2}+T_{2}-4=24[/tex]

so now we can solve this equation for [tex]T_{2}[/tex], so we get:

[tex]2T_{2}+T_{2}+T_{2}=24+4[/tex]

[tex]4T_{2}=28[/tex]

[tex]T_{2}=\frac{28}{4}[/tex]

[tex]T_{2}=7[/tex]

and once we got this answer, we can find the remaining two answers:

[tex]T_{1}=2T_{2}[/tex]

[tex]T_{1}=2(7)[/tex]

[tex]T_{1}=14[/tex]

and

[tex]T_{3}=T_{2}-4[/tex]

so we get:

[tex]T_{3}=7-4[/tex]

[tex]T_{3}=3[/tex]

Answers

Answer:

Look down!!

Step-by-step explanation:

Since two points determine any line, we can graph lines using the x- and y-intercepts. To find the x-intercept, set y = 0 and solve for x. To find the y-intercept, set x = 0 and solve for y. This method of finding x- and y-intercepts will be used throughout our study of algebra because it works for any equation.

Ex.

4=2+2

y=4

x=2

Hope this helps!!

Answer:

Step-by-step explanation:

the y intercept would be 0,2

to find the x intercept plug in a 0 for y

0=-x+2

-2=-x

x=2

the x intercept would be 2,0

so 2,0 0,2 plot those points and draw a line through that. would look something like this

There are 6 yellow hexagons 2 red trapezoids and 9 green triangles how many flowers could you make if they were changed 30 yellow hexagons 50 red trapezoids and 60 green triangles. Which shape would you have left over the most

Answers

Answer:

a) 5 flowersb) Trapezoid

Step-by-step explanation:

For one flower, the following shapes are used;

6 yellow hexagons, 2 red trapezoids and 9 green triangles

If we are given 30 yellow hexagons 50 red trapezoids and 60 green triangles, to get the number of flowers we can make, we will find the greatest common factor of 30, 50 and 60

30 = 6*5

50 = (2*5)+40

60 = (9*5)+15

We can see that 5 is common to all the factors. This means that we can make 5 flowers if they were changed to 30 yellow hexagons 50 red trapezoids and 60 green triangles.

Since there are 40 trapezoids left and 15 green triangles left, hence the shape that would have n as left over most is trapezoid (40 left over)
