how many solutions does the following system of equations have y=2x+2 & 2y=4x+4

Answer:

A) 2481.156[tex]\pi[/tex] cm³

Step-by-step explanation:

The formula for volume of a sphere is: [tex]\frac{4}{3} \pi r^{3}[/tex]. In this case, the radius is 12.3. 12.3 cubed is: 1860.867. 1860.867 x 4 is 7443.468. 7443.468 divided by 3 is 2481.156. Since we haven't multiplied by pi yet, the answer would be 2481.156[tex]\pi[/tex].

Hope it helps!

Answer:

c

Step-by-step explanation:

The two quadrilaterals LMNR and PQNO are not similar. Timo tried to map one figure onto the other using rotation and dilation methods. He concluded that they are not similar because the rigid transformations like rotation preserve congruence and dilation will not change the shape but it changes its size. So, this results in no congruence.

Here Timo used rotation and dilation on the two quadrilaterals LMNR and PQNO. So, this resulted in a change in the size of the quadrilaterals. Because of this, Timo concluded that "it's not possible to map LMNR onto PQNO using a sequence of rigid transformations and dilations, so the quadrilaterals are not similar".

Answer:

105.12 ft²

Step-by-step explanation:

Area of the figure = area of the rectangle + area of half a circle

= L*W + ½(πr²)

Where,

L = 10 ft

W = 8 ft

r = ½ of 8 = 4 ft

π = 3.14

Plug in the values

Area = 10*8 + ½(3.14*4²*)

Area = 80 + 25.12

Area = 105.12 ft²

Answer:

10, 5+5=10

correct answer would be 10

Answer:

[tex]V=47239.2\pi [/tex]

Step-by-step explanation:

We are given that

[tex]y=\sqrt{x}[/tex]

y=0

[tex]x=81[/tex]

When y=0 then x=0

Using shell method

Volume of solid

[tex]V=2\pi \int_{a}^{b}xf(x)dx[/tex]

Using the formula

Volume of solid

[tex]V=2\pi \int_{0}^{81} x(\sqrt{x})dx[/tex]

[tex]V=2\pi \int_{0}^{81}x^{\frac{3}{2}}dx[/tex]

[tex]V=2\pi [\frac{2}{5}x^{\frac{5}{2}}]^{81}_{0}[/tex]

[tex]V=2\pi\times \frac{2}{5}((81)^{\frac{5}{2}})[/tex]

[tex]V=47239.2\pi [/tex]

Answer:

[tex]\large\boxed { \ ANS = \sqrt{5} }[/tex]

Step-by-step explanation:

Irrational numbers are numbers that cannot be written as simple fractions. All the numbers listed above except for [tex]\sqrt{5}[/tex] cannot be written as fractions.

• [tex]\frac{7}{3}[/tex] is already a fraction

• [tex]\frac{-9}{5}[/tex] is also already a fraction

• [tex]\sqrt{9}[/tex] is 3 and 3 can be written as [tex]\frac{3}{1}[/tex]

• [tex]\sqrt{5}[/tex]  is an irrational algebraic number and cannot be written as a simple fraction since it is equal to

The answer should be 3cm

Step-by-step explanation:

The way you worded it was kind of confusing so pardon me if the answer isnt the correct answer you were looking for. But I suppose that if 1 cm is 50 in. than 150 in. would be 3 cm. Because 50 + 50 + 50 = 150. And if it is 1 cm. per 50 in. than that would be 3 cm. I hope this answered your question! And if not.. again, im sorry.

Answer:

[tex]m=\frac{1}{4}[/tex]

Step-by-step explanation:

Given

[tex]y+2=\frac{1}{4}(x-3)[/tex]

Required

Find the slope

[tex]y+2=\frac{1}{4}(x-3)[/tex]

Subtract 2 from both sides

[tex]y+2-2=\frac{1}{4}(x-3) - 2[/tex]

[tex]y=\frac{1}{4}(x-3) - 2[/tex]

Open bracket

[tex]y=\frac{1}{4}x-\frac{1}{4}*3 - 2[/tex]

[tex]y=\frac{1}{4}x-\frac{3}{4} - 2[/tex]

Take LCM

[tex]y=\frac{1}{4}x+\frac{-3 - 8}{4}[/tex]

[tex]y=\frac{1}{4}x+\frac{-11}{4}[/tex]

[tex]y=\frac{1}{4}x-\frac{11}{4}[/tex]

An equation has the form:

[tex]y = mx + b[/tex]

Where

[tex]m = slope[/tex]

By comparing: [tex]y = mx + b[/tex] and [tex]y=\frac{1}{4}x-\frac{11}{4}[/tex]

[tex]m=\frac{1}{4}[/tex]

So, the slope is 1/4

Answer:

Step-by-step explanation:

[3x-2]÷4=2x-8

3x-2 = 4·(2x-8)

3x-2 = 8x-32

-2 = 5x-32

30 = 5x

x = 6

Answer:

(3x-2)/4= 2x-8  x=6

Step-by-step explanation:

(3x-2)/4 times 4= 2x-8

Multiply both sides by 4

3x-2/4 times 4= 2x  times 4-8 time 4

Simplify

3x= 8x = 8x-30-8x

Subtract 8x from both sides

3x-8x=8x-30-8x

Simplify

-5x=-30

Divide both sides by -5

-5x/-5 = -30/-5

Simplify so you get x=6

Answer:

c.

Step-by-step explanation:

The solution is Option C.

Sample space is  set A = { blue , blue } , { blue , green } , { blue , red }

The union of two sets A and B is the set of all those elements which are either in A or in B, i.e. A ∪ B, whereas the intersection of two sets A and B is the set of all elements which are common. The intersection of these two sets is denoted by A ∩ B

The union of two sets is a new set that contains all of the elements that are in at least one of the two sets

The intersection of two sets is a new set that contains all of the elements that are in both sets

Given data ,

Let the sample space be represented as set A

Now , the equation will be

The number of blue cars = 2 blue cars

The number of green cars = 1 green car

The number of red cars = 1 red car

So , the total number of cars = 2 + 1 + 1 = 4 cars

Now , Andy removes 2 race cars from the toy box without looking

Let the first removed car be a blue car

So , the second car can have any value including a blue , green or white

And , the sample space is given by set A

Set A = { blue , blue } , { blue , green } , { blue , red }

Hence , the set is { blue , blue } , { blue , green } , { blue , red }
