Answer:

Step-by-step explanation:

The described points form two right triangles which share same horizontal leg a.

The bottom triangle has 60 m vertical length and 60° opposite angle.

The triangle on the top has unknown (x) vertical length and 30° opposite angle.

We are looking for the distance x + 60 m

On the top triangle we have:

On the bottom triangle we have:

Comparing we get:

So the distance is:

Answer:

x=28

Step-by-step explanation:

Set 2x-4 equal to 60 and solve.

The three angles in the triangle add up to 180. Divide this by 3 and you get 60.

Man, I have to be honest with you, I have no clue. But here is something else though. I had to take Geometry last year, and you are right. It does suck. But, you will get through it! There is a light at the end of the tunnel and you will get it! Keep up the good work!

Answer:

m<1 = 87

Step-by-step explanation:

Bro I got you! You ain't gotta hate school no more!

Right the equation like this

m<1 + m<2 = <TSV (plug in)

m<1 + 65 = 152 (subtract 65 from 152 to get m<1)

m<1 = 87

There you go!

Answer:

We kindly invite you to see the explanation and images attached below.

Step-by-step explanation:

From Geometry we know that every line can be formed by knowing two two distinct points in a plane. Our stategy consist in using two distinct points for each linear equation in order to create our plot.

1) [tex]y = 2\cdot x + 2[/tex], [tex]A(x,y) = (0, 2)[/tex] and [tex]B(x,y) = (1,4)[/tex].

The line [tex]2\cdot y = 4\cdot x + 4[/tex] is a multiple of [tex]y = 2\cdot x + 2[/tex]. We present the graph below.

2) [tex]y = x-5[/tex], [tex]A(x,y) = (0,-5)[/tex] and [tex]B(x,y) =(1,-4)[/tex].

[tex]y = -x+3[/tex], [tex]C(x,y) = (0, 3)[/tex] and [tex]D(x,y) = (1,2)[/tex].

Finally, we proceed to plot each line and present the results below.

3) [tex]y = 2\cdot x-3[/tex], [tex]A(x,y) = (0,-3)[/tex] and [tex]B(x,y) = (1, -1)[/tex].

[tex]y = 2\cdot x + 4[/tex], [tex]C(x,y) = (0,4)[/tex] and [tex]D(x,y) = (1,6)[/tex].

Finally, we proceed to plot each line and present the results below.

Answer:

since the pairs of opposite lines in the diagram are parallel the measurement of B is also 63

to fine A and C simply subtract 180 - 63 which gives us 117 so

A = 117

B = 63

C = 117

D = 63

Answer:

62

Step-by-step explanation:

The total of a triangle is 180

so 78+48 is 118

180-118=62

Given:

Arnold has $24 to spend at the movies.

Ticket = $12

Popcorn is double the price of the soda.

The soda and candy bar are same price.

To find:

The price for the soda.

Solution:

Let x be the price of soda.

According to the question,

Price of candy = Price of soda = x

Price of popcorn = 2(price of soda) = 2x

Total amount = Ticket + Popcorn + Soda + Candy

[tex]24=12+2x+x+x[/tex]

[tex]24=12+4x[/tex]

[tex]24-12=4x[/tex]

[tex]12=4x[/tex]

Divide both sides by 4.

[tex]\dfrac{12}{4}=x[/tex]

[tex]3=x[/tex]

Therefore, the price of soda is $3.

Answer:

a rate

Step-by-step explanation:

A rate is a ratio that compares two different quantities that have different units of measure. A rate is a comparison that provides information such as dollars per hour, feet per second, miles per hour, and dollars per quart, for example. The word “per” usually indicates you are dealing with a rate.

The correct answer is 82% of 50 (41) / 170% of 30 (51) /65% of 80 (52)

Explanation:

The first step to know whether a value is greater than another is to find the value each percentage represents depending on the total. This process is shown below.

1. 65% of 80- This implies 80 is 100% and 85% needs to be found. Use the following formula:

80 / 100 = 0.8 x 65 = 52 or the total number divided by 100 and multiplied by the percentage you want to know

2. 82% of 50 - Repeat the same process

50 / 100 = 0.5 x 82 = 41

3. 170% of 30

30 / 100 = 0.3 x 170 = 51

4. Finally organize the values

82% of 50 (41)

170% of 30 (51)

65% of 80 (52)

Based on the information given about the percentages ,the ordering will be 82% of 50, 170% of 30, and 65% of 80.

It should be noted that 82% of 50 will be:

= 82% × 50

= 41

170% of 30 will be:

= 1.7 × 30

= 51

65% of 80 will be:

= 65% × 80

= 0.65 × 80

= 52

Hey there!

The given points are; (8,2) and (8,4).

Note: Use slope formula.

Now;

[tex]slope(m) = (\frac{y2 -y 1}{x2 - x1}) [/tex]

Keep all values.

[tex]m = \frac{4 - 2}{8 - 8} [/tex]

Simplify it.

[tex] m = \frac{2}{0} [/tex]

When we divide any number by "2" the result is undefined.

Therefore, the slope of the points is undefined.

Answer:

[tex]p=12x-10[/tex]

Step-by-step explanation:

Perimeter is just adding all of the sides' lengths together, so we can put all of them into one big equation and then combine like terms.

[tex]p=x+(2x+5)+(6x-17)+(3x+2)\\p=12x-10[/tex]

Hope this helps!

Dividing fractions is the same as multiplying the reciprocal.

As an easy way to remember this, you can use the Keep it, Switch it, Flip it method.

Keep: [tex]\frac{4}{9}[/tex]

Switch: the division sign to multiplication.

Flip Flip the numbers of [tex]\frac{2}{1}[/tex], or find it's reciprocal. [tex]\frac{1}{2}[/tex] turns into [tex]\frac{2}{1}[/tex].

Now, your problem looks like this:

[tex]\frac{4}{9}[/tex] * [tex]\frac{2}{1}[/tex] (which should be the answer to your first blank)

Multiply across.

4 x 2 = 8 and 9 x 1 = 9, so: [tex]\frac{8}{9}[/tex] should be the second blank.

Answer:

15

Step-by-step explanation:

If we accept that the left side of the left triangle corresponds to the left side of the right triangle, then the scale factor is 6/8 = 3/4. By multiplying the scale factor by the bottom side of the first triangle, you'll get the corresponding side of the right triangle: 20 * 3/4 = 15.

The function that describes the arithmetic sequence is A(n) = 4n + 6

Step-by-step explanation:

The formula of the arithmetic sequence is a[tex]_{n}[/tex] = a + (n - 1)d, where

∵ The terms of the sequence area 10, 14, 18, 22

∵ The first term is 10

∴ a = 10

∵ 14 - 10 = 4

∵ 18 - 14 = 4

∵ 22 - 18 = 4

∴ The common difference is 4

∴ d = 4

→ Substitute them in the formula above

∵ a[tex]_{n}[/tex] = 10 + (n - 1)4

∴ a[tex]_{n}[/tex] = 10 + n(4) - 1(4)

∴ a[tex]_{n}[/tex] = 10 + 4n - 4

→ Add the like terms

∵ a[tex]_{n}[/tex] = 4n + (10 - 4)

∴ a[tex]_{n}[/tex] = 4n + 6

→ Write it in the form of the function A(n)

∴ A(n) = 4n + 6

∴ The function that describes the arithmetic sequence is A(n) = 4n + 6
