Answer:

The answer is C. 119cm³

Step-by-step explanation:

SA= [tex]\pi r^{2} +\pi rl[/tex]

    = 49[tex]\pi +\pi 7(10)[/tex]

    = 49[tex]\pi +20\pi[/tex]

SA= 119[tex]\pi[/tex]

Answer:

The correct answer is option C.   119π cm²

Step-by-step explanation:

Points to remember

Surface area of cone = πrl + πr²

Where r is the base radius and l is the lateral edge

To find the surface area of given cone

Here r = 7 cm and l = 10 cm

Surface area =  πrl + π r² =( π * 7 * 10) + (π *7²)

  = 70 π + 49π

  = 119π cm²

Therefore correct answer is option C.    119π cm²

Answer:

Option 1 and 2 are correct.

Step-by-step explanation:

1. {x:x <-3 or >4}

Here the values of x can be less than -3 or the values of x can be greater than 4. Since 5 is greater than 4 so, 5 is included in the solution

2. {x:x ≥5}

Here the values of x can be greater than or equal to 5. So, 5 is included in the solution.

3. {x:x <5}

Here the values of x can be less than 5. So, 5 is not included in the solution

4. {x:0<x<4}

Here the value of x is greater than 0 but less than 4. So, 5 is not included in the solution

So, Option 1 and 2 are correct.

Answer:

7+24i

Step-by-step explanation:

A math conjugate is formed by changing the sign between two terms in a binomial. For instance, the conjugate of x + y is x - y. We can also say that x + y is a conjugate of x - y. In other words, the two binomials are conjugates of each other.

The conjugate of a complex number is obtained by negating its imaginary part while keeping the real part unchanged. So, for 7 - 24i, the conjugate is 7 + 24i. The real part remains 7, and the imaginary part changes from -24i to +24i.

In the field of mathematics, specifically complex numbers, the conjugate of a complex number is formed by changing the sign of its imaginary part. Given the complex number 7 - 24i, its conjugate is obtained by changing the sign of the imaginary part (-24i) to a positive. So, the conjugate of 7 - 24i is 7 + 24i.

Answer:

120

Step-by-step explanation:

it is an obtuse angle

The answer is:

The missing angle "x" is equal to 130°.

We need to remember that the sum of all of the angles of any polygon will be all equal to 360°.

So, we are given the following exterior angles:

[tex]140\°\\34\°\\56\°\\[/tex]

Now, if the sum of all the exterior angles is equal to 360°, we can use it to calculate "x", so:

[tex]360\°=140\°+34\°+56\°+x\\\\x=360\°-(140\°+34\°+56\°)=360\°-230\°\\\\x=130\°[/tex]

Hence, the missing angle "x" is equal to 130°.

Answer:

d. 40 pounds

Step-by-step explanation:

We know both weights of the astronaut, and we know one of the weight of the rock... we need to find the other weight of the rock (on Earth).

The easiest way to deal with those problems is to use a cross-multiplication.

We'll place on top the weights on Earth and as denominators the weights on Mars:

[tex]\frac{x}{16} = \frac{180}{72}[/tex]

So we isolate x = (16 * 180) / 72 = 2,880 / 72 = 40 pounds.

The rock then weights 40 pounds on Earth.

The question in this problem is:

The sum of 2 consecutive integers is at most the difference between nine times the smaller and 5 times the larger. What are the numbers?

First of all, let's name the first variable [tex]x[/tex] which is the smaller number. Accordingly, the lager number will be [tex]x+1[/tex] given that those numbers are consecutive. On the other hand at most conveys the idea of an inequality, which is:

[tex]\leq \\ which \ means \ less \ than[/tex]

So:

1. The sum of 2 consecutive integers can be written as:

[tex]v+(v+1)[/tex]

2. Nine times the smaller and 5 times the larger can be written as:

[tex]9v-5(v+1)[/tex]

Finally, the whole statement:

The sum of 2 consecutive integers is at most the difference between nine times the smaller and 5 times the larger:

[tex]x+(x+1) \leq 9x-5(x+1) \\ \\ x+x+1\leq 9x-5x-5 \\ \\ 2x+1 \leq 4x-5 \\ \\ 6 \leq 2x \\ \\ [/tex]

[tex]x+(x+1) \leq 9x-5(x+1) \\ \\ x+x+1\leq 9x-5x-5 \\ \\ 2x+1 \leq 4x-5 \\ \\ 6 \leq 2x \\ \\ \frac{6}{2} \leq \frac{2x}{2} \\ \\ 3 \leq x \\ \\ x\geq 3 \\ \\ and \\ \\ x+1 \geq 4[/tex]

The two numbers are:

Plot the points ( -4,2.5), (-3,3), (-2,1.5), (-1,2), (0,1), (1,2), (2,3.5), (3,0.5), (4,2.5) then connect them with a line

the width is equal to a cm.

the length is twice the width, therefore the length is equal to 2a cm.

the height is twice the length, therefore the height is equal to 4a cm.  

the volume is equal to width times length times height which is equal to a * 2a * 4a which is equal to 8a^3 cubic cm.  

For Example:

let a = 5

then 2a = 10

then 4a = 20  

a is the width

2a is the length

4a is the height.  

the length is twice the width.

the height is twice the length  

the volume is equal to a * 2a * 4a which is equal to 8a^3 cubic cm.  

this is equivalent to 8 * 5^3 which is equal to 8 * 125 which is equal to 1000 cubic cm.  

5 * 10 * 20 = 50 * 20 = 1000 cubic cm.  

formula works and so is considered to be good.  

the volume is equal to 8a^3 cubic cm.

* hope you understand*

The volume of a rectangular solid where width equals a cm, length equals twice the width, and the height is twice the length is calculated to be 8a³ cubic cm.

Based on the question, we know that the width of the rectangular solid is a cm. Where the length equals twice the width, so it is 2a cm; likewise, the height, which is twice the length, turns out to be 4a cm. The equation for calculating the volume of a rectangular solid is width * length * height. Therefore, if we substitute the given values, we have a cm * 2a cm * 4a cm, which equals 8a³ cubic cm. As a result, the volume of this given rectangular solid is 8a³ cubic cm.

Answer:

Option: B is the correct answer.      

B)     Decay, y- intercept = 3.4, rate is 34%

Step-by-step explanation:

We are given an exponential equation as follows:

                    [tex]y=3.4(0.66)^x[/tex]

We know that any exponential function of the type:

                                [tex]y=ab^x[/tex]

is growth function if: b>1

and is a decay function if 0< b< 1

Hence, here we have: b=0.66<1

Hence, the function is a decay function.

Also, we know that the y-intercept of a function is the point where x=0

Hence, we take x=0

we have:  [tex]y=3.4\times (0.66)^0\\\\\\y=3.4[/tex]

Hence, the y-intercept is:   3.4

Also, the rate of a function is denoted by 'r'

where b=1-r

    ⇒ 0.66=1-r

   ⇒   r=1-0.66

    ⇒ r=0.34

Hence, the rate is: 34%

          option: B is the correct answer.

Answer:

314 cm²

Step-by-step explanation:

It's not the point O, but the circle O, a point has no area.

The area of a circle is given by the formula A = π r²

We don't have r (radius), but we have the diameter, which is double the radius.  So, r = d / 2 = 20 cm / 2 = 10 cm

Now, we can plug r directly into the equation:

A = π r² = π 10² = 100π = 314 cm²

Answer:

Kyle purchased 12 pencils

Step-by-step explanation:

p= pencils

1.24p - 5.12 = 20

or, you can do this back wards like this....

20 - 5.12 = 14.88

14.88 / 1.24 = 12

p=12

(sorry for any confusion, this is just how my brain works...)

Kyle bought 12 pencils at $1.24 each. This determination is based on subtracting the amount of change he received from his $20 payment and dividing by the cost per pencil.

Kyle bought x pencils for $1.24 each, paid with a $20 bill, and received $5.12 in change. Therefore, the total amount he spent can be calculated by subtracting the change from the total payment ($20 - $5.12 = $14.88). As he spent this amount on pencils that cost $1.24 each, the number of pencils he bought can be determined by dividing the total spent by the cost per item ($14.88 / $1.24). Therefore, Kyle bought approximately 12 pencils (the exact result is 12.003, but as pencils cannot be fractional, we round down to the nearest whole number).

[tex]A=(2x^{2}+9x-18)\ m^{2}[/tex]

Step-by-step explanation:

Let

L-----> the length of the concert hall

W----> the width of the concert hall

we know that

The area of a rectangle ( concert hall) is equal to

[tex]A=LW[/tex]

we have

[tex]L=(x+6)\ m[/tex]

[tex]W=(2x-3)\ m[/tex]

substitute the values

[tex]A=(x+6)(2x-3)\\ \\A=2x^{2} -3x+12x-18\\ \\A=(2x^{2}+9x-18)\ m^{2}[/tex]

The area of the concert hall's floor, in square meters, is represented by the simplified algebraic expression 2x² + 9x - 18, which is derived by multiplying the hall's length (x + 6) by its width (2x - 3) then simplifying the resulting expression.

The area of a rectangle is calculated by multiplying the length by the width. In this case, the length of the concert hall is given as (x + 6) meters and the width as (2x - 3) meters. Therefore, the area of the concert hall's floor, expressed in square meters, is the product of these two expressions.

So, you multiply (x + 6) by (2x - 3) to get the area, which gives you the following expression: 2x² - 3x + 12x - 18. Now, simplify this expression by combining like terms.

The simplified expression for the area of the floor in square meters is then 2x² + 9x - 18.
