Answer:

24

Step-by-step explanation:

4x=12

x=12/4

x=3

8×=?

8(3)=24

therefore, 8 pieces will cost 24.

another way is:

since 8 is 4×2

you could double the amount of money

12x2

which would also give you $24

If charged per cut, it will cost 24 dollar to cut a log into eight pieces if cutting it into four pieces costs $12

The unitary method is a method for solving a problem by the first value of a single unit and then finding the value by multiplying the single value.

Given that to cut a log into eight pieces if cutting it into four pieces costs $12.

Thus,

4x=12

x=12/4

x=3

Hence, for 8 pieces

8(3)=24

therefore, 8 pieces will cost 24.

If charged per cut, it will cost 24 dollar to cut a log into eight pieces if cutting it into four pieces costs $12

Answer:

median = 55.5

Step-by-step explanation:

Here we have 10 numbers which is an even number

then the median for the data set is the average of the two middle numbers

firstly ,we have to put the number of the set in order from least to greatest like this :

3 < 12 < 38 < 38 < 46 < 65 < 71 < 78 < 87 < 99

————————                     ————————-

As you can see the middle two numbers are : 46 and 65

Now, we calculate their average :

[tex]\large \text Median = \frac{46+65}{2}= 55.5[/tex]            

Answer:

p = 43

Step-by-step explanation:

(x²²)(x⁷)³

first, multiply the power of 7 times the power of 3

(x⁷)³ = x⁷ ° ³ = x²¹

second, add the power of (x²²) with (x²¹)

x²² ⁺ ²¹ = x⁴³

therefore, the value of p = 43

Answer:

y2=(1/2)x-9

Step-by-step explanation:

y= -2x-4

perpendicilar so multiplication of slope is -1

-2*m2=-1

m2=1/2

y2=(1/2)x+c need to passes trough (2,-8)

-8=(1/2)*2+c

-8=1+c

c=-9

y2=(1/2)x-9

Answer:

1/4

Let the number be "x"

[tex]3x + 9 = 2x - 4[/tex]

[tex]3x + 9= 2x - 4 \\ \\ \implies 3x - 2x = - 4 - 9 \\ \\ \implies x = - 13[/tex]

[tex] \therefore \text{the required number is = - 13}[/tex]

Answer:

- 35

Step-by-step explanation:

let the number be n then increased by 9 is n + 9 and decreased by 4 is n - 4 , so

3(n + 9) = 2(n - 4) ← distribute parenthesis on both sides

3n + 27 = 2n - 8 ( subtract 2n from both sides )

n + 27 = - 8 ( subtract 27 from both sides )

n = - 35

that is the number is - 35

Because the triangle is an isosceles the base angles are equal so

∠G = ∠F = 65°

Answer:

≈5.15 [cm].

Step-by-step explanation (English version):

1) Capacity - V - 1000 cm³;

height - h - 12 cm;

radius - r - ?

2) the initial formula is:

V=π*r²*h, where π=3.1415;

then final formula of the required r is:

Answer:

34.54

Step-by-step explanation:

11in as diameter

3.14 as pi

11x3.12=34.54

Pls dont get mad if im wrong im trying my best :)

Answer:

73.81 in

Step-by-step explanation:

First we begin with the 3/4 circle perimeter:

(3.14) * diameter * 3/4

[tex](3.14) * 22 * \frac{3}{4} = 51.81[/tex]

Then we add the two remaining lines:

11 + 11 = 22

Adding up these two we get:

[tex]51.81 + 22 = 73.81[/tex]

         ⇒ Perimeter = 10 + 10 + 10 + 10 = 40 ft

        To understand the slant height, look at the diagram I attached

       Slant height: 13 ft

         ⇒ Lateral Area = 4 * (Area of Triangle)

                                    = [tex]4*(\frac{1}{2} *10 * 13) = 4 * 5* 13 = 260ft^2[/tex]

                                    = 260 ft^2

       Area of Base = 10 * 10 = 100ft^2

        Surface Area = Area of Base + Lateral Area

                               = 100 + 260 = 360 ft^2

Hope that helps!
