Answer:

- 7y²

Step-by-step explanation:

(0,01)⁻¹/² × ∛(- 343y⁶/1000) =

= -(1/100)⁻¹/² × ∛( - 7³y⁶/10³)

= - 100¹/² × 7y²/10

= -(10²)¹/² × 7y²/10

= - 10 × 7y²/10

= - 7y²

Answer:

-7y^2

Step-by-step explanation:

(0.01)^(-1/2) = (1/0.01)^(1/2) = 100^(1/2) = 10

(-343 × y^6 ÷ 1000)^(1/3) =

(-343)^(1/3) × (y^6)^(1/3) ÷ 1000^(1/3)

= -7 × y^2 ÷ 10 = -0.7y^2

10 × -0.7y^2

-7y^2

Answer:

Ducks = 8

Horses = 17

Step-by-step explanation:

From the question;

We are required to determine the number of ducks and horses;

We need to know that;

A duck has two legs while a horse has four legs;

Assuming there were x ducks and y horses

Then;

x + y = 25 ................................Eqn 1

And;

2x + 4y = 84 .............................Eqn 2

Solving the two equations simultaneously we can get the number of each animal.

x + y = 25

2x + 4y = 84

Multiplying the first equation by 2, we get

2x + 2y = 50

2x + 4y = 84

Subtracting the two equations;

2x + 2y = 50

2x + 4y = 84

........................................................

      - 2y = -34

          y = 17

Solving for x

x = 25 -17

    = 8

Therefore; there were 8 ducks and 17 horses in the field

Option A:

Lateral surface area = 1319 cm²

Solution:

Given image is the cone.

Radius of the cone = 15 cm

Slant height = 28 cm

Value of π = 3.14

To find the lateral surface area of the cone:

Lateral surface area = [tex]\pi r l[/tex]

                                 [tex]=3.14\times 15\times28[/tex]

                                 =  1318.8 cm²

Change this to nearest whole unit.

Lateral surface area = 1319 cm²

Hence the lateral surface area of the cone is 1319 cm².

Option A is the correct answer.

Answer:

1st and 3rd figures have the same area

Step-by-step explanation:

1st figure is combined figure consisting of 4 m by 5 m rectangle and right triangle with legs

[tex]4-1=3\ m[/tex] and [tex]10-5=5\ m[/tex]

The area of the first figure is

[tex]A_{rectangle}=4\times 5=20\ m^2\\ \\A_{triangle }=\dfrac{1}{2}\cdot 3\cdot 5=7.5\ m^2\\ \\A_{1^{st}\ figure}=20+7.5=27.5\ m^2[/tex]

2nd figure is combined figure consisting of 3 m by 6 m rectangle and right triangle with legs

3 m and [tex]1+3+1=5\ m[/tex]

The area of the second figure is

[tex]A_{rectangle}=3\times 6=18\ m^2\\ \\A_{triangle }=\dfrac{1}{2}\cdot 3\cdot 5=7.5\ m^2\\ \\A_{2^{nd}\ figure}=18+7.5=25.5\ m^2[/tex]

3rd figure is combined figure consisting of 10 m by 2 m rectangle and right triangle with legs

3 m and [tex]10-5=5\ m[/tex]

The area of the third figure is

[tex]A_{rectangle}=2\times 10=20\ m^2\\ \\A_{triangle }=\dfrac{1}{2}\cdot 3\cdot 5=7.5\ m^2\\ \\A_{3^{rd}\ figure}=20+7.5=27.5\ m^2[/tex]

Step-by-step explanation:

Let O represents older brother

M represents middle brother

& Y represents younger brother.

Therefore, according to the given condition:

[tex] \frac{3}{4} y = \frac{2}{3} m = \frac{1}{2} o \\ \\ \therefore \: \frac{3}{4} y = \frac{2}{3} m \\ \implies \: m = \frac{3}{2} \times \frac{3}{4} y = \frac{9}{8} y \\ \\ next \: \: \frac{3}{4} y = \frac{1}{2} o \\ \implies \: o = \frac{2}{1} \times \frac{3}{4} y = \frac{3}{2} y \\ \\ \because \: o + m + y = 58 \\ \\ \therefore \: \frac{3}{2} y + \frac{9}{8} y + y = 58 \\ \\ \therefore \: \frac{12}{8} y + \frac{9}{8} y + \frac{8}{8} y = 58 \\ \\ \therefore \: \frac{29}{8} y = 58 \\ \\ \therefore \: y = 58 \times \frac{8}{29} \\ \\ \therefore \: y = 2 \times 8 \\ \\ \therefore \: y = 16 \: years[/tex]

Thus youngest brother is 16 years old.

Answer:

The correct option is A

Therefore the quadrilateral in the option A can be inscribed in a circle.

Step-by-step explanation:

Given:

Four Quadrilateral, A ,B ,C ,D in the figure below.

For a quadrilateral to be inscribed in a circle we required opposite angles must be supplementary, that is it should add up to 180°.

So from the four given quadrilateral we have only in quadrilateral A the opposite angles are supplementary.

Quadrilateral A :

Consider the quadrilateral PQRS where

∠SPQ = 91°

∠PQR = 101°

∠QRS = 89°

∠SPQ  and ∠QRS  are opposite angles and their sum is 180°

[tex]\angle SPQ+\angle QRS = 91+89 =180[/tex]

Others in option B, C , and D opposite angles are not supplementary hence cannot inscribe in a circle.

Therefore the quadrilateral in the option A can be inscribed in a circle.

Answer:

c Mark me as the brainiest

Step-by-step explanation:

A quadrilateral that can be inscribed in a circle has vertices that lie on a single circle. A distinguishing property of such quadrilaterals is that they have opposite angles adding up to 180°. Non-rectangular parallelograms cannot be inscribed in circles, because their opposite angles are equal rather than supplementary.

Answer:Type of Angle Description

Acute Angle is less than 90°

Right Angle is 90° exactly

Obtuse Angle is greater than 90° but less than 180°

Straight Angle is 180° exactly

Step-by-step explanation:

Answer:

∠ABC = 62°, ∠DBE = 62°, ∠CBE = 118°, ∠ABD = 118°

Step-by-step explanation:

We can say that angle ABC and angle DBE are vertically opposite angles because there are only two intersecting lines. Vertically opposite angles are equal so we can form an equation:

4x + 2 = 5x - 13

5x - 4x = 2 + 13

x = 15

Now we can substitute x into the equation and find out the value for angles ABC and DBE.

4(15) + 2 = 60 + 2 = 62°, just to make sure we need to substitute x into the other equation to see whether we get the same answer:

5(15) - 13 = 75 - 13 = 62°, now we can confirm that angles ABC and DBE are 62°.

Now we can use the rule, angles on a straight line add up to 180°, to find the other two angles, because these two angles are vertically opposite, they are also equal to each other.

180 - 62 = 118°

Angles CBE and ABD are both 118°

Answer:

58 ounces

Step-by-step explanation:

16 x 4=64 - 6=58 ounces

Final answer:

After converting the weight of the cleats from ounces to pounds, the new weight of Bill's baseball bag is determined to be 3.625 pounds by subtracting 0.375 pounds (weight of the cleats in pounds) from the original 4 pounds.

Explanation:

The subject of this question is Mathematics, specifically dealing with unit conversion and simple subtraction of weights. To determine the new weight of Bill's baseball bag after removing the cleats that weigh 6 ounces, we need to first convert the ounces to pounds, since the weight of the bag is given in pounds.

There are 16 ounces in one pound. Therefore, 6 ounces is equivalent to 6 ounces \/ 16 ounces per pound = 0.375 pounds. Starting with the original weight of the bag which is 4 pounds, subtracting the weight of the cleats in pounds will give us the new weight of the bag.

4 pounds - 0.375 pounds = 3.625 pounds. This is the weight of Bill's baseball bag after the cleats are removed.

Answer:1/4

Step-by-step explanation:

The slope is the price of a ticket = 95

The y intercept is the service fee = 11

The equation would be multiplying the price of a ticket (slope) by the number of tickets being purchased (x) and then add the service fee ( y intercept)

Equation: f(x) = 95x + 11

Answer:

The slope is the price of a ticket = 95

The y intercept is the service fee = 11

The equation would be multiplying the price of a ticket (slope) by the number of tickets being purchased (x) and then add the service fee ( y intercept)

Equation: f(x) = 95x + 11

Answer:

18.75 Kg : 11.25 Kg

Step-by-step explanation:

Sum the parts of the ratio, 5 + 3 = 8 parts

Divide 30 Kg by 8 to find the value of one part of the ratio

30 Kg ÷ 8 = 3.75 Kg ← value of 1 part of the ratio, thus

5 parts = 5 × 3.75 Kg = 18.75 Kg

3 parts = 3 × 3.75 Kg = 11.25 Kg

Answer:

  V = (4/3)πr³

Step-by-step explanation:

The formula usually used to find the volume of a sphere is ...

  [tex]V=\dfrac{4}{3}\pi r^3[/tex]

where r represents the radius of the sphere.

The actual math involved will depend on what information about the sphere you are given. If you are given the radius or diameter (twice the radius), then this formula will be directly useful.

To determine the volume of a sphere, use the formula V = ([tex]\frac{4}{3}[/tex])πr³. Measure the radius, cube it, multiply by pi, and then multiply by 4/3.

To find the volume of a sphere, you use the formula:

V = ([tex]\frac{4}{3}[/tex])πr³

Here, V stands for volume, r represents the radius of the sphere, and π (pi) is approximately 3.14159.

Answer:i think it is 0

Step-by-step explanation:

You can use the fact that if (x-root) is a factor of a single variable polynomial function p(x) = 0

A binomial factor of p(x) is (x-2)

Let its root be x = k

Then we have one of the factor of polynomial as (x-k)

Root of a polynomial function p(x) is a value of x such that putting that value in place of x makes the output 0.

Thus, if x = k is a root of the polynomial p(x), then

p(k) = 0

Since it is given that

p(2) + 4=4

thus,

p(2) = 4-4 = 0

Thus, x = 2 is a root of the polynomial function, and thus, using the aforesaid conclusions, we have (x-2) as one of the factors of the considered polynomial function.

Thus,

A binomial factor of p(x) is (x-2)
