Answer:

22

Step-by-step explanation:

Answer:

sin X = [tex]\frac{4}{5}[/tex]

cos X = [tex]\frac{3}{5}[/tex]

tan X = [tex]1\frac{1}{3}[/tex]

Step-by-step explanation:

First, find what the hypothenuse is:

[tex]c^{2} = a^{2} + b^{2}[/tex]

[tex]c^{2} = 18^{2} + 24^{2}[/tex]

[tex]c^{2} = 324 + 576[/tex]

[tex]\sqrt{c^{2}} = \sqrt{900}[/tex]

c = 30

[tex]sine = \frac{opposite}{hypothenuse}\\\\[/tex]

sin x = [tex]\frac{24}{30} = \frac{4}{5}[/tex]

[tex]cosine = \frac{adjacent}{hypothenuse}[/tex]

cos x = [tex]\frac{18}{30} = \frac{3}{5}[/tex]

[tex]tan = \frac{opposite}{adjacent}[/tex]

tan x = [tex]\frac{24}{18} = 1\frac{6}{18} = 1\frac{1}{3}[/tex]

Answer:

sin X = 4/5, or 0.8

cos X = 3/5, or 0.6

tan X = 4/3, or 1.333...

Step-by-step explanation:

Recall that where "o" ≡ "opposite side", "a" ≡ "adjacent side" and "h" ≡ "hypotenuse", then we have three definitions for those function

sin = o/h

cos = a/h

tan = o/a

Before solving two of these then, we'll need to know the length of the hypotenuse, so we'll apply the Pythagorean theorem to find it:

a² = b² + c²

h² = 24² + 18²

h = √(576 + 324)

h = √900

h = 30

So for X, the sine is the length of the opposite side, divided by the length of the hypotenuse, or 24/30:

24 / 30

= 4 / 5

= 0.8

The cosine of x is:

18 / 30

= 3 / 5

= 0.6

Finally the tan of x is:

24 / 18

4 / 3

1.333...

Answer:

46

Step-by-step explanation:

46 lol

its literally inputting in addition

70 - 24 = 46

Answer:

all true

Step-by-step explanation:

Answer:

10

Step-by-step explanation:

we can solve this using basic algebra

We set up the equation using the info that each video costs $5 and that we but 12 of them

12(1 * 5) + x = 70

(Please note: 1x = x)

12(5) + x = 70

60 + x = 70

60 - 60 + x = 70 - 60

x = 10

look in the comments I'll put the answers as I go along x

Answer:

#11 21

Step-by-step explanation:

You have the right steps for question 10, let me work #11 n/3 -5 = 2

So following your steps: move the -5 so n/3 = 2+5 so n/3 = 7, now

multiply both sides by 3 so n = 21

Step-by-step explanation:

Answer:

9800

Step-by-step explanation:

Answer:

9800

Step-by-step explanation:

(100 x 100) - 200

Answer:

The correct answers are the second and third ones.

a=6,b=8,c=10

a=5,b=6,c=61 sqred

Step-by-step explanation:

for the second one, 36+64=100. So 100sqrd is 10.

For the third one, 25+36=61. So 61sqrd.

Answer: 2,160 words

Step-by-step explanation:

Answer:

14 months

Step-by-step explanation:

8 x 14= 112 + 10 = 122

Brandy's subscription was for 14 months.

Given is that a monthly movie subscription is a one-time fee of $10.00 plus $8.00 each month. It is given that Brandy spent $122.00.

We can write the modelled equation as -

8x + 10 = 122

8x = 112

x = 112/8

x = 14

Therefore, Brandy's subscription was for 14 months.

Answer:

B, C, D

Step-by-step explanation:

Given expression  

Note that

Use distributive property:

Thus, choice B is true.

Rewrite given expression in following way:

Thus, choice C is true.

Rewrite given expression in following way:

Thus, choice D is true.

Answer:

[tex]d < \frac{3}{2}x[/tex]

Step-by-step explanation:

Represent a cup with x; the cat with c and the dog with d

From the first statement, we have:

[tex]c < x[/tex]

From the second, we have:

[tex]c = \frac{1}{3}d + \frac{1}{2}x[/tex]

Required

Express d in terms of x

We have:

[tex]c = \frac{1}{3}d + \frac{1}{2}x[/tex] and [tex]c < x[/tex]

Merge both expressions to give:

[tex]\frac{1}{3}d + \frac{1}{2}x < x[/tex]

Collect Like Terms

[tex]\frac{1}{3}d < x - \frac{1}{2}x[/tex]

[tex]\frac{1}{3}d < \frac{1}{2}x[/tex]

Multiply both sides by 3

[tex]3 * \frac{1}{3}d < \frac{1}{2}x * 3[/tex]

[tex]d < \frac{3}{2}x[/tex]

Answer:

It is not always possible to construct a triangle from a given side length and two angles. If the two given angles add to more than 180°, the sides of the triangle will diverge and never meet.

Step-by-step explanation:

Answer:

I think it would be 160 degrees

Step-by-step explanation:

Answer:

160 degrees

Step-by-step explanation:

The whole protractor is 180 degrees. B is at the 180 mark but E is at 20. So, the the angle of BAE would be 180-20=160 degrees.

Answer:

SO evry child gets 1 then you go around again and there will be 2 more, so all you hae to 2 is split hose into halfs and it will be equal :)

Step-by-step explanation:

Answer:

F=140°

Step-by-step explanation:

130+120+110=360

720-360=360

40+60+20=120  360+120=480

480÷3=160  x=160

160-20=140

f=140°

Answer:

B

Step-by-step explanation:

The orthocenter of a triangle is the point of intersection of the three altitudes of the triangle.

In an obtuse triangle, two altitudes are completely outside the triangle; therefore, the three altitudes cannot possibly intersect inside the triangle.

Answer: A

Step-by-step explanation: 3(1)+k =8 8-3=5

Answer:

A. 5

Step-by-step explanation:

Plug each x value into the equation 3x + k

Substitute each answer choice for k

Whenever they match the values under the equation, you have the answer.

3 (1) + 5 = 8

3 (3) + 5 = 14

3 (5) + 5 = 20

Answer:

4 x 8= 32

3 x 2= 6

32 + 6 + 4= 42

Therefore your answer would be 42.
