Step-by-step explanation:

Answer:

(I can't answer if its greater than, less than, or equal to because you didn't

specify the number I have to compare to)

2. [tex]\frac{35}{8}[/tex]

3. greater than

4. [tex]\frac{1}{9}[/tex]

5. [tex]\frac{1}{6}[/tex]

6. [tex]\frac{4}{5}[/tex]

Step-by-step explanation:

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:

1.43 as a decimal

Step-by-step explanation:

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]

Step-by-step explanation:

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].

correct answer would be 10

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 }

Answer:

Jackets cost $69.90.

Step-by-step explanation:

1. Multiply $233 by 70% (.70 as a decimal) to find how much less the jacket is.

2. Subtract that answer from the cost of the jacket.

233 * .70 = 163.1

233.00

163.10

$69.90

You can also multiply $233 by 30% and not have to subtract because your answer would BE the cost (70% + 30% = 100%).

233 * .30 = 69.90                 $69.90

Answer:

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:

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:

Prime numbers are those that cannot be divided by another number (other than themselves and 1). In other words, prime numbers have factors of themselves and 1.

For example, 3 is a prime number because its only factors are 3 and 1.

6 is not a prime number because it can be factored to 3*2.

Therefore, the correct answer is a. 3,11,23,31

[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
