Answer:

24.04 cm

Step-by-step explanation:

each headband uses 4.95cm and each bracelet uses 4.24cm.

4 headbands * 4.95 cm = 19.8cm

1 bracelet * 4.24 cm = 4.24 cm

19.8 cm + 4.24 cm = 24.04 cm

Answer:

Option A

Step-by-step explanation:

   We know that the "3x ? 2" line must be positive, so it cannot be C or D. The other line is negative, so the "2x ? 5" line must be -2x. This gets rid of option B, leaving us with our answer of A!

Answer:

1) (-A+B)=(B-A) is true

Step-by-step explanation:

I am guessing you are looking for which statement is true. The answer is 1, (-A+B)=(B-A), as the others are incorrect.

2) A x 0 = 0, not 1

3) - (-A) = A, not - A

4) A/B will not be the same as B/A unless the values of A and B are 1

Answer:

Cause 25/25 is a whole number and 25/38 is not

Step-by-step explanation:

Answer: Angel observes a marble travel along a horizontal path at a constant rate. The marble travel 2/3 of the length- of the path in 50 seconds. At that rate, how many seconds does it take the object to travel the full length?                                

Step-by-step explanation: First, reason down from 2/3 to 1/3. Enter all values as fractions (proper or improper) or whole numbers. You will need to  convert mixed numbers to improper fractions.

Since Angie has 12 3/4 yards of fabric and all and each costume requires 7/8 yards, you can divide 12 3/4 by 7/8.

12 3/4 ÷ 7/8

= 51/4 ÷ 7/8

= 51/4 • 8/7 (remember that dividing by a fraction is the same thing as multiplying by it’s reciprocal)

= 51/1 • 2/7 (after simplifying)

= 102/7

= 14 4/7

Angie can make 14 costumes. She cannot make the 15th one because she’ll run short of fabric.

Answer:

see explanation

Step-by-step explanation:

Given

cosθ = - [tex]\frac{5}{13}[/tex]

This is a 5- 12- 13 right triangle

with adjacent = 5, opposite = 12 and hypotenuse = 13

In quadrant 3

sinθ < 0 and tanθ > 0 , then

sinθ = [tex]\frac{opposite}{hypotenuse}[/tex] = -  [tex]\frac{12}{13}[/tex] and

cscθ = [tex]\frac{1}{sin0}[/tex] = [tex]\frac{1}{-\frac{12}{13} }[/tex] = - [tex]\frac{13}{12}[/tex]

then

tanθ = [tex]\frac{sin0}{cos0}[/tex] = [tex]\frac{-\frac{12}{13} }{-\frac{5}{13} }[/tex] = - [tex]\frac{12}{13}[/tex] × - [tex]\frac{13}{5}[/tex] = [tex]\frac{12}{5}[/tex]

Answer:

X || Z

Step-by-step explanation:

Step-by-step explanation:

well, what does your own logic tell you ? just think logically.

of course it is X || Z.

what else could it be ?

this is similar to questions like

if A > B, and B > C, then what does that say about A and C ?

right, A > C.

same thing for A=B, B=C, then A=C.

but it does not work with every relationship. so, be careful and just use basic logic - but that you will have to use.

Answer: mathmatical estimate 46 million

Step-by-step explanation:

456million first guess

Answer:

[tex] \cos( \theta) = \frac{5}{8} \\ {8}^{2} = {5}^{2} + {opp}^{2} \\ {opp}^{2} = 64 - 25 = 39 \\ opp = \sqrt{39} \\ \sin(\theta) = \frac{\sqrt{39}}{8} \\ \tan(\theta) = \frac{ \sqrt{39} }{5} \\ \cot(\theta) = \frac{1}{\tan(\theta)} = \frac{1}{\frac{ \sqrt{39} }{5}} \\ \cot(\theta) = \frac{5}{ \sqrt{39} } \\ \csc( \theta) = \frac{1}{\sin(\theta)} = \frac{1}{\frac{\sqrt{39}}{8}} \\ \csc( \theta) = \frac{8}{ \sqrt{39} } \\ \sec( \theta) = \frac{1}{\cos( \theta) } = \frac{1}{ \frac{5}{8} } \\ \sec( \theta) = \frac{8}{5} [/tex]

For given angle [tex]\theta[/tex],

[tex]\bold{cot(\theta)=\frac{5}{6.24}}\\\\ \bold{cos(\theta)=\frac{5}{8}}\\\\ \bold{sec(\theta)=\frac{8}{5}}[/tex]

In a right triangle, for angle Ф

cos(Ф) = adjacent side of angle Ф / hypotenuse

In a right triangle, for angle Ф

cos(Ф) = opposite side of angle Ф / hypotenuse

In a right triangle for an angle Ф,

sec(Ф) = 1 / (cos(Ф))

In a right triangle for an angle Ф,

cot(Ф) = cos(Ф) / sin(Ф)

For a right triangle,

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

where 'c' represents the hypotenuse

'a' and 'b' be the other two sides of the right triangle

For given example,

The adjacent side of [tex]\theta[/tex] is 5 and the hypotenuse is 5.

[tex]\bold {cos(\theta)=\frac{5}{8}}[/tex]

We find the opposite side of the angle [tex]\theta[/tex] using Pythagoras theorem.

Let 'x' be the opposite side of the angle [tex]\theta[/tex] .

By Pythagoras theorem,

[tex]\Rightarrow 8^{2} =x^{2} + 5^{2}\\\\ \Rightarrow x^{2} =64-25\\\\ \Rightarrow x=\sqrt{39}\\\\ \Rightarrow x=6.24[/tex]

So, the opposite side of the angle [tex]\theta[/tex]  is 6.24 units.

[tex]sin(\theta)=\frac{6.24}{8}[/tex]

So, the value of [tex]cot(\theta)[/tex] would be,

[tex]\Rightarrow cot(\theta)=\frac{cos(\theta)}{sin(\theta)}\\\\\Rightarrow cot(\theta)=\frac{\frac{5}{8} }{\frac{6.24}{8} } \\\\\Rightarrow \bold{cot(\theta)=\frac{5}{6.24}}[/tex]

Now we find the value of [tex]\bold{sec(\theta)}[/tex]

[tex]\Rightarrow sec(\theta)=\frac{1}{cos(\theta)}\\\\\Rightarrow sec(\theta)=\frac{1}{\frac{5}{8} }\\\\ \Rightarrow \bold{sec(\theta)=\frac{8}{5}}[/tex]

Therefore, for given angle [tex]\theta[/tex],

[tex]\bold{cot(\theta)=\frac{5}{6.24}}\\\\ \bold{cos(\theta)=\frac{5}{8}}\\\\ \bold{sec(\theta)=\frac{8}{5}}[/tex]

Answer:

C. -12 feet per minute

Step-by-step explanation:

This question is really just asking for the slope of this situation. So the best way to find the answer is to find the change in y over the change in x. In this case, y is the depth and x is the time. So, it would be -48/4 because the diver went down 48 feet when 4 minutes passed. Then, simply divide, -48/4, which equals -12 feet/1 minute.
