Answers

Answer:

x = 5

Step-by-step explanation:

6*(2x+8) = 108

12x + 48 = 108

x =60/12

x = 5

Answer:

x = 5 units

Step-by-step explanation:

The area of a rectangle equals length times widths, therefore we can use the information from the question to make the following equation...

108 = (2x + 8)(6)

Now we just solve the equation and get...

108 = (2x + 8)(6)

108 = 12x + 48

12x = 108 - 48

12x = 60

x = 60 / 12

x = 5

Therefore, x = 5 units.

Apple and cranberry juice are mixed in a ratio of 5 to 3. What amount of each juice would be needed to make a 64-fluid ounce pitcher of apple-cranberry juice?

Answers

Answer:

32

Step-by-step explanation:

64/2=32

Answer:

[tex]\text{Apple juice needed: }40\:\mathrm{oz},\\\text{Cranberry juice needed: }24\:\mathrm{oz}[/tex]

Step-by-step explanation:

Let [tex]a[/tex] be the amount of apple juice needed, in ounces. Let [tex]c[/tex] be the amount of cranberry juice needed, in ounces. We can set up the following system of equations:

[tex]\begin{cases}a=\frac{5}{3}c, \\a+c=64\end{cases}[/tex]

Solving, we get:

[tex]\frac{5}{3}c+c=64,\\\\\frac{8}{3}c=64,\\\\c=\frac{64\cdot 3}{8}=\boxed{24\:\mathrm{oz}}[/tex]

[tex]a=\frac{5}{3}c,\\\\a=\frac{5}{3}(24),\\\\a=\boxed{40\:\mathrm{oz}}[/tex]

Joan has a piece of material for making a costume. She needs to cut it as shown. What is the angle measure of the piece left over?

Answers

Answer:

50 degrees

Step-by-step explanation:

Since it is a right angle, right angle meaning 90 degrees, subtract 40 from 90

90 - 40 = 50

we have 50 degrees.

(?) what is the relationship between the 81 degree angle ? what is the measure of this angle ?

Answers

Answer:

A. They are corresponding and vertically opposite

B. Rigid Motion:

Any way of moving all the points in the plane such that. a) the relative distance between points stays the same and. b) the relative position of the points stays the same. There are four types of rigid motions that we will consider: translation , rotation, reflection, and glide reflection.

C: 81

Step-by-step explanation:

Here the angle opposite to the 81 degree will also be 81 degree ( vertically opposite angles)
Now the angle opposite to x degree will be 82 (alternate angles)
And lastly x degree is equals to 81 degree( vertically opposite angle)

For any right triangle, the side lengths of the triangle can be put in the equation a2 + b2 = c2 where a, b, and c are the side lengths. A triangle with the side lengths 3 inches, 4 inches, and 5 inches is a right triangle. Which way(s) can you substitute the values into the equation to make it true? Which variable has to match the longest side length? Why?

Answers

Answer:

Pythagorean theorem:

a² + b² = c²

a is the long leg of the triangle

b is the short leg of the triangle

c is the hypotenuse

side lengths ; 3 inches, 4 inches, 5 inches of a right triangle.

a = 4 inches

b = 3 inches

c = 5 inches

4² + 3² = 5²

Which dimensions can create only one unique triangle?
A.) 3 angles measuring 75 degrees, 45 degrees, and 50 degrees
B.) 3 sides measuring 14 m, 11 m, and 18 m
C.) 3 angles measuring 40 degrees, 50 degrees, and 60 degrees
D.) 3 sides measuring 3 cm, 4 cm, and 8 cm

Answers

Answer:

B)

Step-by-step explanation:

A, C, and D multiple choice answers have no chance of becoming a triangle because the lengths don't add up to either 180 or 90. Also, Triangle B follows the rule that 2 sides and be greater than the other side.

Answer: Choice B)

3 sides measuring 14 m, 11 m, and 18 m

=================================================

Explanation:

Let's go through choices A through D to see which result in one unique triangle, or could produce (infinitely) many triangles, or produce no triangles at all.

Choice A produces no triangles at all. Why is this? The angles don't add up to 180. We see that 75+45+50 = 170. The three angles must add to 180 degrees for a triangle to form. Choice B produces one single triangle, which is why it's the final answer. The triangle inequality theorem can be used here to show that a triangle can be formed. The SSS (side side side) congruence theorem is then used to show that exactly one unique triangle is possible. Choice C is a similar story to choice A. We can rule it out. This time we have the angles add to 40+50+60 = 150 which is short of 180.Choice D can be ruled out too. The two sides a = 3 and b = 4 add to a+b = 3+4 = 7, but that's smaller than c = 8. We must have a+b > c to be true if we wanted to form a triangle. For more info, see the triangle inequality theorem.

Even if the angles did add to 180 (for either choice A or choice C), then we'd have infinitely many triangles and not one unique triangle. Think of dilating the triangles and how each dilated image retains the same angles. In other words, the triangles keep the same shape. Simply knowing the three angles is not enough info to create one unique triangle. We would need to know some info about the sides. This explains why AA or AAA is not a congruence theorem.

Answers

Answer: 12?????? i dont know what the question is saying bc ur took a picture of something too close maybe get the whole question?

Step-by-step explanation:

Part A

y varies directly with x, so we know that y = kx for some constant k. Why the letter 'c' isn't used as a constant, instead of k, I'm not entirely sure.

We're told that x = 0.5 and y = 36. Let's use those values to find k

y = kx

36 = k*0.5

36/0.5 = k

72 = k

k = 72

The equation y = kx updates to y = 72x

As a check, plug x = 0.5 in to get,

y = 72x

y = 72*0.5

y = 36

which helps show that we have the correct equation.

Answer: y = 72x

===============================================================

Part B

If y = 1/3, then,

y = 72x

1/3 = 72x

72x = 1/3

x = (1/3)*(1/72)

x = (1*1)/(3*72)

x = 1/216

Note how I multiplied both sides by 1/72, which is the same as dividing both sides by 72.

Answer:  x = 1/216

Answer:

In lowest terms, there is a 1/3 probability of Jason pulling out a baseball card.

Step-by-step explanation:

There are a total of 6 cards. 4/6 of them are football and wrestling which results in 2 baseball cards. So the probability is 2/6 but since the question wants it in lowest terms, you would have to simplfy 2/6. Divide the top by 2 and the bottom by 2 which gets you 1/3.
