Answer:Options 'A' and 'C' are correct.

Step-by-step explanation:

Let the number of sheep be 's'.

Let the number of goats be 'g'.

According to question, we have given that

the number of sheep and goats are not more than 43.

The number of goats are fewer than 22.

So, the inequalities would be

[tex]g<22\\\\and\\\\s+g<43[/tex]

Hence, Options 'A' and 'C' are correct.

The two inequalities for Harold's sheep and goats situation are A. g < 22 and C. s + g ≤ 43.

To represent the situation described about Harold's sheep and goats, we need to set up two inequalities based on the given information:

Using these inequalities, we can help Harold determine how to distribute his sheep and goats in the new field.

The domain is the set of all point where you can evaluate the function.

As you can see, the first piece is defined from -infinity to 2 (included).

The second piece is defined from 2 to 6 (excluded).

The third piece is defined from 6 (excluded) to +infinity.

So, the domain of the function is composed by all the real numbers which are not 6:

[tex](-\infty,6)\cup(6,\infty) = \mathbb{R}\setminus\{6\} = \{x \in \mathbb{R}\ :\ x\neq 6\}[/tex]

As for the range, it is the set of all values taken by the function. We can see that the first piece spans the y axis from 0 to infinity.

The second piece is constantly equal to 2, so it adds nothing.

The third piece spans the y axis from -2 to -infinity, so the range is

[tex](-\infty,-2)\cup[0,\infty) = \mathbb{R}\setminus [2,0) = \{x \in \mathbb{R}\ :\ x\geq 0\ \lor\ x<-2\}[/tex]

1.8y is the answer because first you do 3/4y into a decimals number and then it’s 0.75 then I times it by 2.4 which is 1.8y

To solve the equation 3/4 y = 2.4x for y, we multiply both sides of the equation by 4/3 to eliminate the fraction. Simplifying the equation gives us y = 3.2x. The constant of proportionality in this equation is 3.2.

To solve the equation 3/4 y = 2.4x for y, we need to isolate y on one side of the equation. First, we can multiply both sides of the equation by 4/3 to eliminate the fraction:

3/4 * y = 2.4x

y = (2.4x)/(3/4)

Next, we can simplify the equation by multiplying the numerator and denominator of the fraction by the reciprocal of 3/4, which is 4/3:

y = (2.4x) * (4/3)

y = (9.6x)/3

y = 3.2x

Therefore, the equation 3/4 y = 2.4x can be solved for y to give the expression y = 3.2x. The constant of proportionality in this equation is 3.2, which indicates that y is directly proportional to x with a scale factor of 3.2.

Answer: FIRST OPTION

Step-by-step explanation:

You need the formula for calculate the arc lenght:

[tex]arc\ length=2\pi r(\frac{C}{360})[/tex]

Where  "r" is the radius and and "C" is the central angle in degrees.

You know that the radius is:

[tex]r=7.5[/tex]

And the central angle ∠CAT is:

[tex]C=\angle CAT=125\°[/tex]

Then, you need to substitute these values into the formula  [tex]arc\ length=2\pi r(\frac{C}{360})[/tex] to calculate the length of CT.

Then, this is:

 [tex]arc\ length=CT=2\pi (7.5)(\frac{125\°}{360})[/tex]

[tex]arc\ length=CT=16.4[/tex]

Answer:

a + b = 63

a - b = 12

So, a - b = 12 which can also be written as a = b + 12

Then use substitution and plug in (b + 12) for a in the first equation

(b+12) + b =63

-12              -12

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

2b  =  51 so b=25.5

Now, you know b which can be used to find a

63- 25.5= 37.5

So, a = 37.5 and b = 25.5

Answer:

Answer:

The height of the prism is [tex]1\frac{1}{6}[/tex] units ⇒ answer a

The number of blocks needed is 133 ⇒ answer c

Step-by-step explanation:

* Lets explain how to solve the problem

- The volume of a rectangular prism is

→ V = Area of the base × its height

- The volume of the rectangular prism is [tex]3\frac{25}{36}[/tex] units³

- The area of its base is [tex]3\frac{1}{6}[/tex] units²

- Substitute the values of the volume and area of the base in the rule

∴ [tex]3\frac{25}{36}=3\frac{1}{6}*h[/tex]

- Divide the two sides by [tex]3\frac{1}{6}[/tex]

∴ [tex]h=\frac{7}{6}=1\frac{1}{6}[/tex] units

* The height of the prism is [tex]1\frac{1}{6}[/tex] units

- The volume of each cubic block is [tex]\frac{1}{36}[/tex] units³

- The number of blocks = volume of the prism ÷ volume of the block

∵ The volume of the prism is [tex]3\frac{25}{36}[/tex] units³

∵ The volume of each block is [tex]\frac{1}{36}[/tex] units³

∴ The number of blocks = [tex]3\frac{25}{36}[/tex] ÷ [tex]\frac{1}{36}=133[/tex]

∴ The number of blocks = 133

* The number of blocks needed is 133

The expression represents the volume of the cone that is times the volume of the pyramid that it fits inside is Pi/4(4r²/3).

We have given that the expression represents the volume of the cone

that is times the volume of the pyramid that it fits inside

(2r^2h) (4r^2h)

The formula for the volume of a cone is ⅓ r^2h cubic units.

where r is the radius of the circular base and h is the height of the cone.

Answer:

5 · a³ · b³ · √5b

Step-by-step explanation:

Start with √(50a^6b^7).  Rewrite 50 as the product of the largest possible perfect square and a multiplier:  50 = 25 · 2.  Then √50 = 5√2.

a^6 is already a perfect square, so find its square root:  √a^6 = a^3.

b^7 = b · b^6, so √b^7 = b^3√b

Now rewrite (50(a^6) (b^7)) as √(50a^6b^7).

Then rewrite √(50a^6b^7) as 5√2 · a³ · b³ · √b.

This latter result can be simplified to 5 · a³ · b³ · √5b

This matches possible answer #1.

Answer:

Step-by-step explanation:

When two triangles are similar, their corresponding sides are in proportion. The length of NO cannot be determined from the given information.

When two triangles are similar, their corresponding sides are in proportion. In this case, the scale factor is 3/2, meaning that the corresponding sides of triangle ABC and triangle MNO are in the ratio of 3:2.

To find the length of side NO, we can set up the proportion:

AB/MN = BC/NO = AC/OO

Since we know that AB = 3 and MN = 2, we can solve for NO:

3/2 = BC/NO

3NO = 2BC

NO = (2/3)BC

Therefore, the length of NO is (2/3) times the length of BC.

Since we don't know the length of BC, we cannot determine the exact length of NO. The answer choices provided do not match the information given, so none of the given options can be correct.

Let

x-----> the measure of arc EVL

y----> the measure of arc EHL

[tex]m<EYL=\frac{1}{2}(x-y)[/tex]

[tex]m<EYL=\frac{1}{3}(y)[/tex]

so

[tex]\frac{1}{3}y=\frac{1}{2}(x-y)[/tex]

Multiply by 6 both sides

[tex]2y=3x-3y[/tex]

[tex]y=(360\°)*(3)/8=135\°[/tex]

Find the value of x
