What is the measure of the smallest angle?

one line has 2x #2 had 3x - 11 #3 had 2x + 9

67°
69°
52°
61°

Step-by-step explanation:

Since y is on a straight line, it'll be easy

The degree of a straightine is 180

You have one angle of 57, so all we do is subtract 57 from 180

180-57 = 123

The probability of drawing a black card in a standard deck of 52 cards is 1/2.

Probability of an event is a number that indicates how likely the event is to occur. It is expressed as a number in the range from 0 and 1. There are total 52 cards out of which 26 are black cards and 26 are red cards.

There are 26 black cards (13 spades and 13 clubs) in a standard deck of 52 cards.

Therefore, the probability of drawing a black card from a standard deck of 52 cards is 26/52.

Probability = 26/52 = 1/2

So, the probability of drawing a black card is 1/2.

First, we need to convert the volume of the juice in the jar from liters to milliliters, since the volume of the glasses is given in milliliters.

1 liter = 1000 milliliters

So, 70 liters = 70 * 1000 = 70,000 milliliters

Next, we'll divide the volume of the juice in the jar by the volume of each glass to find out how many glasses can be filled with the juice.

70,000 milliliters ÷ 150 milliliters/glass = 466.67 glasses (rounded to the nearest whole number)

Therefore, 466 glasses can be filled completely with the juice.

Finally, we can find out how much juice is left in the jar by subtracting the total volume of the juice used to fill the glasses from the volume of the juice in the jar.

70,000 milliliters - (466 glasses x 150 milliliters/glass) = 70,000 milliliters - 69900 milliliters = 800 milliliters

So, 800 milliliters of juice is left in the jar.

Answer:

x = 25.4

Step-by-step explanation:

the exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.

139° is an exterior angle of the triangle, then

5x - 25 + 37 = 139

5x + 12 = 139 ( subtract 12 from both sides )

5x = 127 ( divide both sides by 5 )

The total volume of lemonade held by 24 bottles would be 18,000 mL (750 mL x 24) or 24x 0.75 liters = 18 liters.

And it would be to express the total volume in terms of the volume of one bottle. You can say that 24 bottles of lemonade is equal to 18 times the volume of one bottle, or 18 x 750 mL = 18,000 mL. This can also be written as 24 x 0.75 liters = 18 liters. This can also be expressed as 18 liters, since 1 liter is equal to 1000 mL.

Regardless of how you choose to express the answer, both methods give us the same result: 24 bottles of lemonade hold a total of 18,000 mL or 18 liters of the beverage. This information can be useful in various contexts, such as for planning a party or for ordering supplies for a lemonade stand. It's important to note that while both answers give the same result, they present the information in different ways. The first answer provides the total volume of lemonade held by all 24 bottles, while the second answer provides the number of times the volume of one bottle is contained within the total volume. Both answers provide useful information and the choice of which one to use may depend on the specific context in which the question is being asked.

For given geometrical shape, The angles which we need to find are  ∠z=115° and y=21.

What are geometric shapes, exactly?

Geometric shapes are mathematical figures that reflect the shape of objects we see in our daily lives. Shapes are geometric shapes that have boundary lines, angles, and surfaces. There are several types of 2d and 3d shapes.

Shapes are also classified according to their regularity or homogeneity. A symmetrical regular form, such as a square or circle, is common. Asymmetry can take on irregular shapes. They're also referred to as organic forms or freeform shapes. A tree, for example, has an irregular or organic shape.

In plane geometry, two-dimensional forms are flat shapes and closed figures such as circles, squares, rectangles, rhombuses, and so on. In solid geometry, the three-dimensional shapes are the cube, cuboid, and sphere.

Now,

In given figure ∠z+65°=180°    (Sum of two interior angles)

then ∠z=115°

and ∠z=∠6y-11   (vertically opposite angles)

6y-11=115

Answer:

A large container is a better deal because for a large container the amount of jam per dollar is greater thank that in the three smaller containers.

Step-by-step explanation:

What is the volume of a cylinder?

The volume of a cylinder is given by -

V[c] = πr²h

Given is Terrel who has to buy either one large jar or three small jars of jam. A small jar has a diameter of 6 cm, a height of 7 cm, and costs $4. A large jar has a diameter of 8 cm, a height of 16 cm, and costs $12.

For one large container, its volume will be -

V[L] = πr²h = 22/7 x 4 x 4 x 16 = 804.56 cm³

Amount of jam per dollar = V[1] = 804.56 / 12 = 67.04 cm³

For three small containers, the total volume will be -

V[S] = πr²h = {22/7 x 3 x 3 x 7} x 3 = 594 cm³

Amount of jam per dollar = V[2] = 594 / 12 = 49.5 cm³

It can be seen that for a large container the amount of jam per dollar is greater than that in the three small container. Hence, a big container would be a better deal for Terrell.

Therefore, a large container is a better deal because  for a large container the amount of jam per dollar is greater than that in the three small container.

Work Shown:

n = number of nickels

22-n = number of dimes

5n = value of the nickels in cents

10(22-n) = value of the dimes in cents

5n+10(22-n) = total value in cents

5n+10(22-n) = 180

5n+220-10n = 180

-5n+220 = 180

-5n = 180-220

-5n = -40

n = -40/(-5)

n = 8 is the number of nickels

22-n = 22-8 = 14 is the number of dimes

-----------------

Check:

8 nickels = 8*5 = 40 cents

14 dimes = 14*10 = 140 cents

8 nickels + 14 dimes = 40 cents + 140 cents = 180 cents = $1.80

8 nickels + 14 dimes = 22 coins total

e) (f ∘ g)(x) = √(√x + 5) + 5

f) (h ∘ f)(x) = 2 - 1/ (√x + 5)

What is Function?

A function is an expression or relationship that involves one or more variables. It has several inputs and outputs.

a) (f ∘ g)(4) means plugging in the value of 4 into g(x) and then plugging the result into f(x). So we have:

g(4) = √4 + 5 = √9 = 3

f(g(4)) = f(3) = √3 + 5 = 2

Therefore, (f ∘ g)(4) = 2.

b) b) (g ∘ f)(4) means plugging in the value of 4 into f(x) and then plugging the result into g(x). So we have:

f(4) = √4 = 2

g(f(4)) = g(2) = √2 + 5

Therefore, (g ∘ f)(4) = √2 + 5.

c) (h ∘ g ∘ g)(-5) means plugging in the value of -5 into g(x) twice, and then plugging the result into h(x). So we have:

g(-5) = √(-5) + 5 = √(20) = 2√5

g(g(-5)) = g(2√5) = √(2√5) + 5

h(g(g(-5))) = h(√(2√5) + 5) = 2 - 1/ (√(2√5) + 5)

Therefore, (h ∘ g ∘ g)(-5) = 2 - 1/ (√(2√5) + 5).

d) (g ∘ f)(x) means plugging in the function f(x) into g(x), which gives:

g(f(x)) = √(x + 5) + 5

Therefore, (g ∘ f)(x) = √(x + 5) + 5.

e) (f ∘ g)(x) means plugging in the function g(x) into f(x), which gives:

f(g(x)) = √(√x + 5) + 5

Therefore, (f ∘ g)(x) = √(√x + 5) + 5.

f) (h ∘ f)(x) means plugging in the function f(x) into h(x), which gives:

h(f(x)) = 2 - 1/ (√x + 5)

Therefore, (h ∘ f)(x) = 2 - 1/ (√x + 5).

Answer:

(4-g) X 1.5

Step-by-step explanation:

The value of k in the exponential function is -3.

Taking the natural logarithm of both sides of the equation, we have:

ln [ (1 + 65/x)^(3x) ] = ln(e^k)

Using the properties of logarithms, we can simplify the left side of the equation:

3x ln(1 + 65/x) = k

Taking the limit as x approaches infinity, we have:

lim (x → ∞) 3x ln(1 + 65/x)

= lim (x → ∞) [ln(1 + 65/x) / (1/x)] × 3

Using L'Hopital's rule, we can evaluate the limit:

lim (x → ∞) [ln(1 + 65/x) / (1/x)]

= lim (x → ∞) [-65 / (x(1+65/x))]

= -65/65

= -1

Therefore, we have:

lim (x → ∞) 3x ln(1 + 65/x)

= lim (x → ∞) [ln(1 + 65/x) / (1/x)] × 3

= -3

the probability of getting a head on the next flip is estimated to be 0.81. The probability of getting two heads in a row would be the square of this probability, or 0.81 * 0.81 = 0.6561.

The probability of getting a head on any single flip of a fair coin is 1/2. However, based on the results of the previous 100 tosses, we can estimate the probability of getting a head on the next flip as the ratio of heads to total tosses, which is 81/100 or 0.81. So, the probability of getting a head on the next flip is estimated to be 0.81. The probability of getting two heads in a row would be the square of this probability, or 0.81 * 0.81 = 0.6561. The mathematical concept of probability quantifies the possibility that an event will occur. A number between 0 and 1, where 0 denotes an improbable event and 1 denotes a certain event, is used to express it. Events with intermediate probabilities (between 0 and 1) indicate a likelihood of occurrence that is between impossible and certain. The sum of the probabilities of all possible outcomes of an event must equal 1.
