Answer:

C. 6 packages

Step-by-step explanation:

4 divided by 2/3

=>4x3/2=6

mark me as the brainliest plz

Given 4 yards of ribbon and each package requires 2/3 yard, Kris can wrap 6 packages.

This question is about dividing total resources, in this case, ribbon, by the amount needed for each unit, in this case, a package. Kris has 4 yards of ribbon, and each package requires 2/3 yard of ribbon to wrap. To find out how many packages Kris can wrap, we need to do a division: total yards of ribbon ÷ yards of ribbon per package.

The equation for this would be: 4 ÷ 2/3. When we divide by a fraction, we multiply by its reciprocal. The reciprocal of 2/3 is 3/2, so we set up the equation like this: 4 x (3/2).

The answer to this equation is 6. Hence, Kris can wrap 6 packages with 4 yards of ribbon.

Answer:

T.A. = 144 + 36√3

Step-by-step explanation:

The pyramid has a regular triangle for a base.  The other three faces are isosceles triangles.

The height of base can be found by dividing it into two right triangles.  We can either use properties of a 30-60-90 triangle, or use Pythagorean theorem.

h = 6√3

So the area of the base is:

A = 1/2 bh

A = 1/2 (12)(6√3)

A = 36√3

Similarly, the height of the three isosceles triangles can be found by dividing them into two right triangles and using Pythagorean theorem.

h = √(10² - 6²)

h = 8

So the area of the isosceles triangles is:

A = 1/2 bh

A = 1/2 (12)(8)

A = 48

So the total surface area of the pyramid is:

T.A. = 3(48) + 36√3

T.A. = 144 + 36√3

The measure of the consecutive angle x is 50 degrees in the given rhinestone. The given angles are supplementary angles.

A rhombus shape has also been named a diamond. Its properties are as follows:

The measure of one of the angles = 130 degrees

The angle x is supplementary to the given angle. So, their sum is 180 degrees. I.e.,

130 + x = 180

⇒ x = 180 -130

⇒ x = 50°

Thus, the measure of the angle x is 50°.

Answer:

b² - 4ac = 0

Step-by-step explanation:

The nature of the roots of a quadratic equation are determined by the discriminant, that is

• If b² - 4ac > 0 then roots are real and distinct

• If b² - 4ac = 0 then roots are real and equal

• If b² - 4ac < 0 then roots are not real

x = - 3 indicates an equal root, hence b² - 4ac = 0

The domain is the input value of an equation/ graph, which is the X value.

The X value on a graph is the horizontal axis across the bottom.

The X-axis for this is the months, so the answer is The domain represents a 11-month period of flower production.

The slope is the amount of change in the value of y for every one unit increase in the value of x. Thus, what we are looking for is, if the value of x increases by 1, by how much will the value of y increase (or effectively decrease, if this value is negative)?

From the graph, we can see that as x increases, y decreases, therefor we know that this will be a negative number. Furthermore, if we look at the points (0, 1) and (4, 0), we can see that there has been a decrease of 1 unit (or an increase of -1 units) in the y-value for an increase of 4 units in the x-value. Thus, if we wanted to find how much the y-value increases for a one unit increase in the x-value we would have -1/4.

This also reflects the formula for the gradient being rise/run - there has been a 'rise' of -1 (negative since it has fallen rather than risen) and a 'run' of 4 (this refers to the amount of units in the x-direction).

Now we can see that either C or D is the answer.

To find the y-intercept, we simply look at what the y-value is when x = 0; looking at the graph, we can see that y = 1 when x = 0, thus the y-intercept is 1.

Given that the gradient is -1/4 and the y-intercept is 1, we can see that the answer is C.

Answer: OPTION C

(c) slope = Negative one-fourth, y-intercept = 1

This represents additive identity property.

This property states if zero is added to any number we get the same number.i.e if 0 is added to y then we get y (y+0=y)

So, Option C is correct

Final answer:

The missing reason in the proof that demonstrates –(–y – x) – x equals y is the Additive Identity Property, which indicates adding zero to a number does not change its value.

Explanation:

The question refers to a series of algebraic manipulations with the aim of proving the equation –(–y – x) – x = y. The final step in the proof involves the simplification of y + 0 to y. The correct reason for this step is the Additive Identity Property, which states that adding zero to any number does not change the value of that number. Therefore, the missing reason in the proof is option C.

Using the converse of Pythagoras

If the square of the longest side equals the sum of the squares on the other 2 sides then the triangle is right.

longest side = 39

39² = 1521

36² + 15² = 1296 + 225 = 1521

The triangle is right since 36² + 15² = 39²

Answer:

Step-by-step explanation:

If a ≤ b <c is the length of the sides of a right triangle, then:

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

We have

[tex]a=15\ in,\ b=36\ in,\ c=39\ in[/tex]

Check the equality:

[tex]L_s=15^2+36^2=225+1296=1521[/tex]

[tex]R_s=39^2=1521[/tex]

[tex]L_s=R_s[/tex]

It's a right triangle.

For this case we must find the product of the following expressions:

[tex](-2x ^ 3 + x-5) (x ^ 3-3x-4)[/tex]

We apply distributive property, that is, we multiply term by term, taking into account that:

[tex]-2x ^ {3 + 3} + 6x^{3 + 1} + 8x ^ 3 + x ^ {1 + 3} -3x1 + 1 -4x-5x ^ 3 + 15x + 20 =\\-2x ^ 6 + 6x ^ 4 + 8x ^ 3 + x ^ 4-3x ^ 2-4x-5x ^ 3 + 15x + 20[/tex]

If we multiply:

[tex](x ^ 3-3x-4) (- 2x ^ 3 + x-5)[/tex]

Answer:

90

Step-by-step explanation:

13.5/.15

To solve this you must use a proportion like so...

[tex]\frac{part}{whole} = \frac{part}{whole}[/tex]

15 is a percent and percent's are always taken out of the 100. This means that one proportion will have 15 as the part and 100 as the whole

We want to know out of what number is 13.5 15% of. This means 13.5 is the part and the unknown (let's make this x) is the whole.

[tex]\frac{13.5}{x} =\frac{15}{100}[/tex]

Now you must cross multiply

13.5*100 = 15*x

1350 = 15x

To isolate x divide 15 to both sides

1350/15 = 15x/15

90 = x

This means that 15% of 90 is 13.5

The system of equations with y = -4x and y = 2x + 3 has no solution.

The system of equations with y = -4x and y = 2x + 3 has no solution. To determine this, we can set the two equations equal to each other and solve for x:

-4x = 2x + 3

Adding 4x to both sides, we get:

0 = 6x + 3

Subtracting 3 from both sides, we get:

-3 = 6x

Dividing both sides by 6, we get:

-1/2 = x

Substituting x = -1/2 back into either equation will result in a false statement, indicating that the system has no solution.

Answer:

The measure of one exterior angle is 45 degrees.

Step-by-step explanation:

The formula to find exterior angle of and shape is 360 degrees divided by n (number of sides the shape has). 360 divided by 8 = 45 degrees.

Answer:

Exterior angle = 45°

Step-by-step explanation:

We know that the sum of exterior angles of a polygon is 360 degrees.

Since here we a regular polygon with eight sides (which makes it an octagon) so this means that the interior angles each would be equal to:

[tex]\frac{(n - 2) \times 180}{n} \\ \frac{(8 - 2) \times 180}{8}\\ \frac{6 \times 180}{8} \\ \frac{1080}{8} [/tex] = 135 degrees

We know that each interior angle is supplementary to the exterior angle at the vertex.

So each exterior angle = [tex]180-135[/tex] = 45 degrees

Answer:

about 50 000 i think sorry if this didnt hep

Step-by-step explanation:

To calculate the previous population before a 15% increase that resulted in a current population of 59,800, we use the formula: Previous Population = Current Population / (1 + Percentage Increase), which yields a previous population of approximately 52,000.

The question pertains to determining what the previous population of a city was before it experienced an increase of 15%. Given that the current population is 59,800, we can calculate the previous population using the formula:

Current Population = Previous Population * (1 + Percentage Increase)

To find the Previous Population, we rearrange this formula:

Previous Population = Current Population / (1 + Percentage Increase)

By substituting in the given values:

Previous Population = 59,800 / (1 + 0.15)

Previous Population = 59,800 / 1.15

Previous Population = 52,000 (approximately)

Therefore, the previous population of the city was around 52,000 inhabitants before the 15% increase.
