Answer:

40

Step-by-step explanation:

Let's call blueberries, raspberries, grapes and cherries b, r, g, and c respectively. We can write:

b + r + g + c = 280 (1)

r = 2b (2)

g = 3c (3)

c = 4r (4)

We can plug (2) into (1) to get b + 2b + g + c = 280. Then, we can re-write (4) into r = c / 4 and plug that into (2) which gets us c / 4 = 2b, and when we re-write that we get c = 8b (5). Let's plug that into (1) to get b + 2b + g + 8b = 280. Next, we'll re-write (3) to get g / 3 = c, and we can plug that into (5) to get g / 3 = 8b so then g = 24b and plug that into (1) to get b + 2b + 24b + 8b = 280 → 35b = 280 → b = 8. We can plug this into (5) to get c = 8 * 5 = 40. Hope this helps!

The partial derivative with respect to x at the given point is 2e^4, and the partial derivative with respect to y at the given point is 8e^4.

To find the partial derivatives of f(x,y) = exy^2, we differentiate f with respect to x and y, treating the other variable as a constant. So,

fx(x,y) = y^2exy^2

fy(x,y) = 2xyexy^2

At the point (ln 2, 2), we have:

fx(ln 2, 2) = 2e^4

fy(ln 2, 2) = 8e^4

Therefore, the partial derivative with respect to x at the given point is 2e^4, and the partial derivative with respect to y at the given point is 8e^4.

These partial derivatives give us information about how the function changes in each direction at the given point.

Based on the formula of the quadratic function y=-x^2+6x-5, we know that its graph is a downward-facing parabola that opens wide, with a vertex at (3,-14), and an axis of symmetry at x=3.

Based on the formula of the quadratic function y=-x^2+6x-5, we can determine several properties of its graph, including its shape, vertex, and axis of symmetry.

First, the negative coefficient of the x-squared term (-1) tells us that the graph will be a downward-facing parabola. The leading coefficient also tells us whether the parabola is narrow or wide. Since the coefficient is -1, the parabola will be wide.

Next, we can find the vertex using the formula:

Vertex = (-b/2a, f(-b/2a))

where a is the coefficient of the x-squared term, b is the coefficient of the x term, and f(x) is the quadratic function. Plugging in the values for our function, we get:

Vertex = (-b/2a, f(-b/2a))

= (-6/(2*-1), f(6/(2*-1)))

= (3, -14)

So the vertex of the parabola is at the point (3,-14).

Finally, we know that the axis of symmetry is a vertical line passing through the vertex. In this case, it is the line x=3.

Home plate to second base is located at a distance of 90√2 feet.

A square is a rectangle in which each side is the same length. The distance separating the square's opposing vertices is known as the diagonal. The Pythagoras Theorem can be used to compute the diagonals:

Diagonal² = Side² + Side²

Diagonal² = 2 Side²

Diagonal = √2 Side

The answer to the question is that it is 90 feet from home plate to first base.

This is the length of the side that makes up the baseball diamond's square shape. The diagonal of the square is the distance from home plate to second base.

Diagonal = √2 Side

Diagonal = 90√2

Hence, home plate to second base is located at a distance of 90√2 feet.

"A baseball diamond is square. The distance from home plate to first base is 90 feet. In feet, what is the distance from home plate to second base?"

Answer:

6 is the the distance between the points

The required distance between coordinates (-3, 4) and (-3, 10) is 6 units.

Given that,
The distance between the coordinates (-3, 4) and (-3, 10) is to be determined.

Coordinate, is represented as the values on x - axis and y - axis of the graph. where the values of the x-coordinate are called abscissa and the values of y coordinate are called ordinate.

Let the distance between two points be C.
Tio determined the distance between two points \((x_1, y_1)\) and (\(x_2,y_2\)) is given by the distance formula
C = √(x_1-x_2)^2(y_1-y_2)^2}

Putting the given coordinate in the above formula.

C = (-3+3)^2+(4 -10)^2}
C = {(0)^2+(6)^2}
C = √36
C = 6

The required distance between points is 6 units.

Thus, the required distance between coordinates (-3, 4) and (-3, 10) is 6 units.

The measure of ∠ABC in the triangle below is 60°

Triangle is a polygon with three sides and three angles. The sum of angles in a triangle is 180°.

∠ACB + 135 = 180° (Sum of angles in a straight line)

∠ACB = 45°

In triangle ABC:

∠ABC + ∠ACB + ∠CAB  = 180° (Sum of angle in a triangle)

∠ABC + 75 + 45 = 180

∠ABC = 60°

Step-by-step explanation:

The ratio of cats to dogs was 3:7

Divide 300 by 3

=100

multiply 100 and 7

=700

Step-by-step explanation:

let common ratio be x

3x + 7x = 300

10 x = 300

x = 300/10= 30

there common ratio x is 30

3 x 30 =90 cats

7 x 30 = 210 dogs

Answer:

x = 45°

y = 90°

Step-by-step explanation:

    The 135° is on a line, so 180° - 135° = 45°

Since this is an isosceles triangle, x will be equal to 45° as well.

    The sum of a triangle's angles is 180°, so if we add them all together and subtract from 180° we will get our y.

180° - (45 + 45) = y

180° - 90° = y

90° = y

(a triangle can be both an isosceles and a right-triangle!)

Answer:

Area is 64cm^2
Diagonal is 11.3cm

Step-by-step explanation:

To find the area of a square, you need to multiply the length of one side by itself. In this case, the side length is 8 cm, so the area of the square is 8 x 8 = 64 square centimeters.

To find the diagonal of a square, you need to use the Pythagorean theorem. This states that in a right triangle, the square of the length of the hypotenuse (the longest side) is equal to the sum of the squares of the lengths of the other two sides. In this case, the diagonal of the square will be the hypotenuse of a right triangle with two sides that are each 8 cm long. So, to find the diagonal, we need to find the square root of 8 squared plus 8 squared, which is equal to the square root of 64 + 64, or the square root of 128. This means the diagonal of the square is approximately 11.3 cm.

What is questionnaire?

A questionnaire is a type of research tool used to collect data from respondents for a survey or statistical analysis. It consists of a set of questions (or other forms of prompts). Typically, a research questionnaire will have both closed-ended and open-ended questions. Long-term, open-ended inquiries provide the respondent the chance to go into more detail. The Statistical Society of London created the research questionnaire in 1838. Although statistical analysis of the replies is frequently the goal of questionnaire design, this is not always the case.
