If 5 potatoes together have a mass of 1 kilometer and 8 pears together have a mass of 1,200 grams, which has the greater mass a potato or a pear? Explain.

Answer:

B) 7 cans

Step-by-step explanation:

First task is to determine how many square units we have.

With the rectangle spanning 2 units on the X-axis and 3 unites on the Y-axis, we know that it has an area of 6 square units.

The two triangle shapes sum up to one unit total, since a triangle's area is (base * height) / 2.  Both have a base of 1 unit, and a height of 1 unit... so  (1 * 1) / 2  = 1/2 for each triangle.  Together, they occupy 1 unit.

So, total is 7 square units. Let's imagine it as a 7-unit by 1-unit rectangle, it will be easier to calculate.  Each unit is 5 feet.  So, this rectangle measures 35 (7 * 5) feet long, by 5 (1 * 5) feet wide... for a total of 175 (35 * 5) sq feet.

Since a can of paint can cover 25 sq feet, he'll need 7 cans (175 / 25).

Answer:

V = 1138.77333333 cm^3

Step-by-step explanation:

The volume of a cone is given by

V = 1/3 pi r^2 h

We know the diameter so we can find the radius

d = 16

r = d/2

  = 16/2 =8

The radius is 8

V = 1/3 pi (8)^2 * 17

V = 1088/3 *pi

Using 3.14 for pi

V = 1138.77333333 cm^3

Answer:

D  110

Step-by-step explanation:

Vertical angles are equal

50 = x+2y

Adjacent angles equal 180 degrees when they make a straight line

50+x-2y = 180

subtract 50 from each side

50-50+x-2y = 180-50

x-2y = 130

Flipping sides on the first equation

x+2y = 50

Adding the two equations together

x-2y = 130

x+2y = 50

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

2x = 180

Divide by 2

2x/2 = 180/2

x = 90

Now we need to find y

x+2y = 50

90 +2y = 50

Subtract 90 from each side

90-90+2y = 50-90

2y = -40

Divide by 2

2y/2 = -40/2

y = -20

We want the difference between x and y

x-y

90-(-20)

90+20

Answer:

7

Step-by-step explanation:

The left hand limit is when we approach zero from left. We use the function on this domain in finding the limit.

[tex]\lim_{x \to 0^-} f(x)=7-x^2[/tex]

[tex]\lim_{x \to 0^-} f(x)=7-(0)^2=7[/tex]

The right hand limit is

[tex]\lim_{x \to 0^+} f(x)=10x+7[/tex]

[tex]\lim_{x \to 0^+} f(x)=10(0)+7=7[/tex]

Since the left hand limit equals the right hand limit;

[tex]\lim_{x \to 0} f(x)=7[/tex]

ANSWER

[tex]y = - \frac{8}{x} [/tex]

EXPLANATION

An inverse variation equation is of the form:

[tex]y = \frac{k}{x} [/tex]

We plug in the point (-1,8).

[tex] 8= \frac{k}{ - 1} [/tex]

This implies that k=-8

Therefore the inverse variation equation is :

[tex]y = - \frac{8}{x} [/tex]

Final answer:

The set of points {(-1,8),(4,-2),(-2,4)} represents an inverse variation with the equation xy = -8, as the product of x and y is consistently -8 for all given points.

Explanation:

An inverse variation can be defined by an equation of the form xy = k, where k is a nonzero constant. Given the set of points {(-1,8),(4,-2),(-2,4)}, we can find the constant k by multiplying the x-coordinate with the y-coordinate for each point, as follows:

(-1)(8) = -8

(4)(-2) = -8

(-2)(4) = -8

Since the product of x and y is consistent and equal to -8 across all points, we can confirm that k = -8 and thus the equation representing this relation is xy = -8.

This relation is a function because a function [tex]f[/tex] from a set [tex]A[/tex] to a set [tex]B[/tex] is a relation that assigns to each element [tex]x[/tex] in the set [tex]A[/tex] exactly one element [tex]y[/tex] in the set [tex]B[/tex]. The set [tex]A[/tex] is the domain (also called the set of inputs) of the function and the set [tex]B[/tex] contains the range (also called the set of outputs). So we have that:

[tex]\left[\begin{array}{cc}x & y\\4 & 5\\8 & 7\\12 & 9\\16 & 11\end{array}\right][/tex]

All these points have been plotted below, so you can realize this is a linear function. Therefore, with two points we can get the equation, so:

[tex]The \ equation \ of \ the \ line \ with \ slope \ m \\ passing \ through \ the \ point \ (x_{1},y_{1}) \ is:\\ \\ y-y_{1}=m(x-x_{1}) \\ \\ \\ y-5=\frac{7-5}{8-4}(x-4) \\ \\ y-5=\frac{2}{4}(x-4) \\ \\ y=\frac{1}{2}x+5-2 \\ \\ y=\frac{1}{2}x+3 \\ \\ \\ Where: \\ \\ (x_{1},y_{1})=(4,5) \\ \\ (x_{2},y_{2})=(8,7)[/tex]

Finally, the equation is:

[tex]\boxed{y=\frac{1}{2}x+3}[/tex]

The volume is 45 I think

The cylinder shown has a volume of 90 cubic units. The cone and the cylinder have the same height and the same base. The volume of the cone will be 30 cubic units.

It is defined as the three-dimensional shape in which the base is a circular shape and if we go from circular base to top the diameter of the circle reduces and at the vertex, it becomes almost zero.

Given:

The volume of the cylinder= 90 cubic units

The volume of the cylinder=πr²h

90 cubic units=πr²h

The volume of a cone is;

[tex]\rm V= \frac{1}{3} \pi r^2h \\\\ V=\frac{1}{3} \times 90 \ cubic units \\\\ V=30 \ cubic \ units[/tex]

Hence, the volume of the cone will be 30 cubic units.

166 = 166

Answer:

15. 6 ft

Step-by-step explanation:

Your calculation is correct

note h = 15.6 ft ( to the nearest tenth of a foot )

Yes,your calculation is correct

Find the vertex: -4x^2 + 16x - 7​

Vertex = ( x, f(x)).

x = -b/2a

x = -16/2(-4)

x = -16/-8

x = 2

f(x) = -4x^2 + 16x - 7

Let x = 2

f(2) = -4(2)^2 + 16(2) - 7

f(2) = -4(4) + 32 - 7

f(2) = -16 + 32 - 7

f(2) = 16 - 7

f(2) = 9

Vertex = (2, 9)

The weight of 20 buckets is 141 Kg.

The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.

For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.

12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.

As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.

This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.

Given:

weight of 1 bucket of gravel = 7.05

weight of 20 buckets = 7.05 x 20

                                  = 141 Kg

Hence, the weight of 20 buckets is 141 Kg.

Question

One bucket of gravel has a mass of 7.05 kg. what is the mass of 20 buckets of gravel in kilograms?

The measure of G is 28 because it is an isosceles triangle

The measure of G depends on the given information or the type of angle it represents.

The measure of G refers to the numerical value or the angle of G. To determine the measure of angle G, we need more information, such as the type of angle or any given angles in the problem. However, if we assume that G is a generic angle, we can measure it using a protractor or rely on the properties of different types of angles.

For example, if G is a right angle, it measures 90 degrees. If G is a straight angle, it measures 180 degrees. But without specific details, it is challenging to determine the exact measure of G.

Remember to always provide more information in order to find the measure of an angle accurately.

Answer:

Step-by-step explanation:

The equation of a circle in standard form is

(x - h)² + (y - k)² = r²

where (h, k) are the coordinates of the centre and r is the radius

Given

8x + x² - 2y = 64 - y²

Collect the x/y terms, leaving 64 on the right side, that is

x² + 8x + y² - 2y = 64

To obtain standard form use the method of completing the square.

add ( half the coefficient of the x/y terms )² to both sides

x² + 2(4)x + 16 + y² + 2(- 1)y + 1 = 64 + 16 + 1

(x + 4)² + (y - 1)² = 81 ← in standard form
