X = 1/3 (to make it short) plz brainliest

Step-by-step explanation:

Answer:

[tex]\theta=16.6^{\circ}[/tex]

Step-by-step explanation:

Given that,

The surface of the ramp will be 7 feet long with a total rise of 2 feet.

We need to find the angle of elevation of the ramp. We can use trigonometry to find it such that,

[tex]\sin\theta=\dfrac{P}{H}[/tex]

P is perpendicular

H is hypotenuse

Here, P = 2 feet, H = 7 feet

So,

[tex]\sin\theta=\dfrac{2}{7}\\\\\theta=16.6^{\circ}[/tex]

So, the angle of elevation of the ramp is equal to [tex]16.6^{\circ}[/tex].

Answer:

A, 1.8796

Step-by-step explanation:

First, convert everything to inches

6 × 12 = 72

72 + 2 = 74

Now, we convert the inches to centimeters

2.54 × 74 = 187.96

Next, we convert to meters

187.96 ÷ 100 = 1.8796

So, your answer would be A, 1.8796 meters

Have a great day!

Answer:

C

Step-by-step explanation:

The reason we shall be choosing the graph c is as a result of the plot type

Now, looking at the inequalities, we can see that the second inequality does not have an equal to assigned

Whenever we want to plot this kind of inequality, we are going to use the dotted line in place of the thick line used in cases where we have the equal to assigned to the inequality

So, what this looks like is that only the option C has the correct representation of the dotted line and thus represents our answer

Answer:

false

Answer:

16

Step-by-step explanation:

Shape C is A trapezoid

Area of trapezoid = [tex]\frac{a+b}{2} h[/tex]

where a and b =  base lengths and h = height

The trapezoid has the following dimensions

base 1 = 3 units

base 2 = 5 units

height = 4 units

Using these dimensions we plug in the values into the formula stated above.

[tex]A=\frac{3+5}{2} 4\\3+5=8\\\frac{8}{2} =4\\4*4=16[/tex]

Hence the area of shape C = 16 square units

Answer:

rectangle A's area: 12, 3 x 4 = 12

Area b: 1 x 4 = 4 divided by 2 = 2, the base is 1 height is 4. Multiply given lengths, then multiply by 1/2 because formula of a triangle is BH x 1/2. To get your answer of 2.

Area C: 3 + 5 = 8, 8 x 4 = 32, 32 divided by 2 = 16, formula of a trapezoid is base 1 + base 2 x height x 1/2. In this case 5 is your base and base 2 is 3. Add them up to get 8. We then multiply 8 by the height which is 4 if you count from the top to bottom in the middle. 8 x 4 = 32. 32 x 1/2 = 16 (basically just dividing by 2).

Answer:

3 minutes and 34 seconds

Answer:

Bob's can make one burger in 0.3 minutes, or 18 seconds.

Step-by-step explanation:

Bob's can make 10 hamburgers in 3 minutes. To determine how long it takes Bob's to make a single hamburger, we divide the 3 minutes by the 10 hamburgers.

3/10 = 0.3 minutes

It takes him 0.3 minutes to make one burger.

We could go further and convert this time to seconds. To do this, we multiply 0.3 minutes by 60 seconds.

0.3 ⋅ 60 = 18 seconds

Bob's can make one hamburger in 18 seconds.

Answer:

-9,-4

Step-by-step explanation:

Answer:

the required numbers are -4 and -9.

Step-by-step explanation:

-9×-4=36

-9+(-4)=13

18 would be your answer for because it says 18 out of 24 words he got correctly

Answer:

solution given :

<A=?

<B=50°

<C=50°

if it is a triangle:

<A+<B+<C=180°( sum of interior angle of a triangle is 180°)

<A=180-50-50

<A=80°

<A=80° is a required answer.

Its a isosceles triangle

So

<A:-

Step-by-step explanation:

Answer:

The given equation having only one solution i.e., "w = 3". A further explanation is provided below.

Step-by-step explanation:

The given equation is:

⇒ [tex]9(w-9)-2=-7w+7(w-8)[/tex]

By opening the brackets, we get

⇒ [tex]9w-81-2=-7w+7w-56[/tex]

⇒ [tex]9w-83=-56[/tex]

On adding "83" both sides, we get

⇒ [tex]9w-83+83=-56+83[/tex]

⇒                 [tex]9w=27[/tex]

⇒                   [tex]w=\frac{27}{9}[/tex]

⇒                       [tex]=3[/tex]

Answer:

I'm pretty sure it is 2/15

Answer:

5 meters

Step-by-step explanation:

The values given, 3 and 4, are the legs a and b. The hypotenuse is the third and longest side, c.

To find the length of the hypotenuse, use the formula a² + b² = c².

Substitute our values for a and b and solve.

a² + b² = c²

3² + 4² = c²

9 + 16 = c²

25 = c²

√25 = √c²

5 = c

The hypotenuse is 5 meters long.

so 8 times 33=264

402-264=138

Answer:

mCH = 22°

Step-by-step explanation:

Since a secant and tangent intersect on the outside of a circle, the measure the angle formed by them or x would be 1/2 the difference of the larger and smaller arcs intercepted. The larger arc would be AC, while the smaller would be CH. We can model the situation using an equation:

m<X = 1/2(mAC - mCH)

And we can substitute:

68 = 1/2(158 - mCH)

136 = 158 - mCH

mCH = 22°
