-16/35

Step-by-step explanation:

4/7 ÷ -5/4

=> 4/7 × -4/5

=> -16/35

We know that it took 18 hours to drive 666 miles. If we divide the distance by the hours (666 miles)/(18 hours)

We find that 666/18= 37 miles per hour . which means we travel 37 miles each hour.

So, we can estimate that driving 37 miles it will take 1 hour (the distance to Chicago).

Answer:

666/18=37miles/hour

it would take 1 hour to drive 37 miles

The width and height of the rectangular display is 50 feet and 28 feet, respectively.

Using algebraic expression and equation, we can find the dimensions of the rectangular display.

Let x be the height of the display

If its width is 6 feet less than twice its height, then the width can be represented as the algebraic expression:

2x - 6 = width of the display

If the area of the display is 1400 square feet, then the equation to represent this relationship:

A = height x width

1400 = x(2x - 6)

Expanding the expression on the right-hand side:

1400 = 2x² - 6x

Dividing the whole equation by 2,

x² - 3x - 700 = 0

Factor the equation,

(x - 28)(x + 25) = 0

x = 28 ; -25

Taking the positive dimension,

height = 28 feet

So the height of the display is 28 feet. To find the width, we can use the expression we derived earlier:

width = 2x - 6

width = 2(28) - 6

width = 50 feet

So the width of the display is 50 feet.

Answer:

-2.41

Step-by-step explanation:

rearrange:

12x + 10 + 5x + 31

Or

12x + 5x + 10 + 31

Simplify and set that is = to zero so we can isolate x

17x + 41 = 0

To solve for x, we can isolate x on one side of the equation by subtracting 41 from both sides:

17x = -41

Finally, we can solve for x by dividing both sides by 17:

x = -41/17

therefore, x is equal to approximately -2.41 when we plug it back into the original equation:

12x + 10 + 5x + 31 = 0

12(-2.41) + 10 + 5(-2.41) + 31 = 0

-28.92 + 10 - 12.05 + 31 = 0

0 (which is true)

The radius of the spherical part is 3 inches and the length of the tube is 21 cm.

The capacity of a cylinder, which determines how much material it can hold, is determined by the cylinder's volume. There is a formula for the volume of a cylinder that is used in geometry to determine how much of any quantity, whether liquid or solid, can be immersed in it uniformly.

Given that the volume when the water is fully dipped is 4554 / 7 cm³. The volume when the length is 9 cm empty is 396 cm³.

The two equations can be formed as below:-

4554 / 7 = πr²l + (2/3)πr³

396 = πr²( l - 9 ) + (2/3)πr³

Subtract the second equation from the first,

( 4554 / 7 ) - 396 = 9πr²

9πr² = 254.5

r² = 9

r = 3 cm

The length will be calculated as:-

4554 / 7 = πr²l + (2/3)πr³

4554 / 7 = π( 3 )²l + (2/3)π(3)³

l = 21 cm

Therefore, the tube's length is 21 cm, and the spherical part's radius is 3 inches.

The final answer is: 5 quarts, 1 pint, and 0.5 cups based on conversion.

To add these two quantities, we first need to convert all of the measurements to a common unit. Since we are adding pints and cups, we can convert everything to cups, and then convert back to pints and quarts as needed.

5 pints is equal to 5 x 2 = 10 cups (since there are 2 cups in a pint).

2 cups is 2 cups.

3 pints is equal to 3 x 2 = 6 cups.

3 cups is 3 cups.

Now we can add the quantities:

10 cups + 2 cups + 6 cups + 3 cups = 21 cups

To convert 21 cups back to pints and quarts, we can use the fact that there are 2 cups in a pint, and 4 cups in a quart.

First, we can divide 21 by 4 to find the number of quarts:

21 cups ÷ 4 = 5 with a remainder of 1 cup

So we have 5 quarts and 1 cup. To convert the remaining cup to pints, we can divide by 2:

1 cup ÷ 2 = 0.5 pints

Therefore, the final answer is:

5 quarts, 1 pint, and 0.5 cups.

No, you can’t multiply a monomial and binomial together and have a product of a monomial.

using trignometric ratio of sine thee measure of the angle x to the nearest degree is 28 degrees

Trigonometric ratios are ratios of the sides of a right triangle, such as sine, cosine, and tangent, that are used to find missing side lengths or angles.

An angle is a geometric figure formed by two rays or line segments that share a common endpoint, known as the vertex. It is typically measured in degrees or radians.

According the given information:

We can use the trigonometric ratio of sine to find the measure of the angle x.

sin(x) = opposite/hypotenuse

In this case, the opposite side is the height of the triangle, which is 13, and the hypotenuse is the length of the diagonal line connecting the base and the top of the triangle. We can use the Pythagorean theorem to find the length of the hypotenuse.

hypotenuse² = base² + height²

hypotenuse² = 22² + 13²

hypotenuse² = 769

hypotenuse ≈ 27.73

Now we can substitute the values into the sine ratio:

sin(x) = 13/27.73

x ≈ 28 degrees

Therefore, the measure of the angle x to the nearest degree is 28 degrees.

110.25 daps are equivalent to 42 dips. We can use the given values of equivalent measures to get to the required measure: 4 daps = 3 dops, which can be written as 1 dap = (3/4) dops, 2 dops = 7 dips, which can be written as 1 dop = (7/2) dips.

Given: 4 daps = 3 dops and 2 dops = 7 dips

We need to find: how many daps are equivalent to 42 dips?

Solution: We can use the given values of equivalent measures to get to the required measure:

4 daps = 3 dops, which can be written as 1 dap = (3/4) dops

2 dops = 7 dips, which can be written as 1 dop = (7/2) dips

Using the above relations we can find the relation between daps and dips: 1 dap = (3/4) dops = (3/4) * (7/2) dips = (21/8) dips

Or we can write, 8 daps = 21 dips

To find how many daps are equivalent to 42 dips, we can proceed as follows: 8 daps = 21 dips

1 dap = 21/8 dips

Therefore, to get 42 dips, we need: (21/8) * 42 dips = 110.25 daps (Answer)

Thus, 110.25 daps are equivalent to 42 dips. Given that 4 daps = 3 dops and 2 dops = 7 dips, we need to find how many daps are equivalent to 42 dips. This problem requires us to use equivalent measures of the given units to find the relation between the required units. As per the given values of equivalent measures, 4 daps are equivalent to 3 dops and 2 dops are equivalent to 7 dips. Using these values, we can find the relation between daps and dips as follows:

1 dap = (3/4) dops = (3/4) * (7/2) dips = (21/8) dips Or, 8 daps = 21 dips

Thus, we have found the relation between daps and dips. Now we can use this relation to find how many daps are equivalent to 42 dips. To find how many daps are equivalent to 42 dips, we can use the relation derived above as follows: 1 dap = 21/8 dips

Therefore, to get 42 dips, we need:(21/8) * 42 dips = 110.25 daps

Hence, 110.25 daps are equivalent to 42 dips.

The constant of proportionality = 2 trees cut down per day spent on the island.

Explanation

The total number of trees he cut down is y

The number of days Harry is stranded on the island is x

The fact that these two quantities are directly proportional to each other is represented as

y ∝ x

If we introduce the constant of proportionality, we will write it as

y = kx

To now obtain the constant of proportionality, we will use the graph of the relationship between x and y. The costant of proportionality is the same as the slope of the graph

For a straight line, the slope of the line can be obtained when the coordinates of two points on the line are known. If the coordinates are (x₁, y₁) and (x₂, y₂), the slope is given as

For this question, the two points are

The radian measure of the acute angle between the given planes is approximately 0.920.

Find the angle between the planes?

To find the angle between two planes, we need to find the angle between their normal vectors.

Let's first rewrite the equations of the planes in the form Ax + By + Cz = D, where z = 0.

For the first plane, we have 6x + 5y = 10, so we can rewrite it as 6x + 5y + 0z = 10, which gives us A = 6, B = 5, C = 0, and D = 10.

For the second plane, we have 9x + 7y + 62 = 11, so we can rewrite it as 9x + 7y + 0z = -51, which gives us A = 9, B = 7, C = 0, and D = -51.

The normal vectors of the planes are then <6, 5, 0> and <9, 7, 0>, respectively.

To find the angle between these normal vectors, we can use the dot product formula:

cos(theta) = (n1 . n2) / (|n1| |n2|),

where n1 and n2 are the normal vectors of the planes, and theta is the angle between them.

Plugging in the values, we get:

cos(theta) = (6*9 + 5*7 + 0*0) / (√(6²2 + 5² + 0²) *√(9² + 7² + 0²))

cos(theta) = 87 / (√(61) * √(130))

cos(theta) = 0.687

To find the acute angle, we take the inverse cosine of 0.687:

theta = cos^-1(0.687)

theta = 0.812 radians

Rounding to the nearest thousandth, we get:

theta = 0.812 radians (to the nearest thousandth).

To find the angle between the planes 6x + 5y = 10 and 9x + 7y + 62 = 11, we need to first find the normal vectors for each plane. A normal vector is a vector that is perpendicular to the plane.

For the first plane, 6x + 5y = 10, the normal vector (N1) is <6, 5, 0>.
For the second plane, 9x + 7y + 62 = 11, the normal vector (N2) is <9, 7, 0>.

Next, we need to find the angle between these two normal vectors. We can do this using the dot product formula and the magnitudes of the normal vectors.

The dot product of N1 and N2 is:
N1 • N2 = (6 * 9) + (5 * 7) = 54 + 35 = 89

The magnitude of N1 is:
||N1|| = √(6² + 5²) = √(36 + 25) = √61

The magnitude of N2 is:
||N2|| = √(9² + 7²) = √(81 + 49) = √130

Now, we can find the cosine of the angle (θ) between the normal vectors using the dot product formula:

cos(θ) = (N1 • N2) / (||N1|| ||N2||) = 89 / (√61 * √130)

Now, we can find the angle (θ) in radians:

θ = arccos(89 / (√61 * √130))

Round the angle to the nearest thousandth:

θ ≈ 0.920 (rounded to the nearest thousandth)

So, the radian measure of the acute angle between the given planes is approximately 0.920.
