Answer:

1/3

Step-by-step explanation:

We need to simplify the given radical form . Some properties that we will use is ,

[tex]:\implies[/tex] √a / √b = √[ a/b]

The given radical form is ;-

[tex]:\implies[/tex] √2/√18

[tex]:\implies[/tex] √[ 2/18]

[tex]:\implies[/tex] √[ 1/9]

[tex]:\implies[/tex] √[1/3²]

[tex]:\implies[/tex] 1/3

Step-by-step explanation:

8x-8 = -64

8+ -8 =0

Answer:

geometric with r = 2

Step-by-step explanation:

An arithmetic sequence has a common difference between consecutive terms

6 - 3 = 3

12 - 6 = 6

24 - 12 = 12

48 - 24 = 24

96 - 48 = 48

As we see the differences are not common, so not arithmetic

A geometric sequence has a common ratio between consecutive terms.

6 ÷ 3 = 2

12 ÷ 6 = 2

24 ÷ 12 = 2

48 ÷ 24 = 2

96 ÷ 48 = 2

There is a common ratio of 2, so sequence is geometric

with 5th term = 48

Answer:

2827.43, second option

Step-by-step explanation:

v=pi * r^2 * h  is the formula, H= height, r=radius, v= volume

so plug it all in:

3.14 * 5^2 * 12

square the 5 just to make it easier for the calculator

3.14 * 25 * 12= 942

the volume of ONE container is 942, so if you are finding the volume of ALL THREE, then you multiply 942 by three 2826. find the option that goes best with that number

Answer:

$0.407291667 per ounce

Step-by-step explanation: there are 16 ounces in a pound.   16 times 3 is 48.

in order to find the price per ounce, we need to divide the total price by the number of ounces

19.55/48 is 0.407291667

Answer: 14

Step-by-step explanation:

Answer:

Vertex form

y = -4(x + 3)^2 + 10

Standard form;

y = -4x^2-24x - 26

Step-by-step explanation:

Mathematically, we have the vertex form as

y = a(x-h)^2 + k

(h,k) represents the vertex

We have h as -3 and k as 10

y = a(x+3)^2 + 10

To get a, we substitute any of the points

Let us use (-1,-6)

-6 = a(-1+3)^2 + 10

-6-10 = 4a

4a = -16

a = -16/4

a = -4

So we have the equation as;

y = -4(x+3)^2 + 10

For the standard form;

We expand the vertex form;

y = -4(x + 3)(x + 3) + 10

y = -4(x^2 + 6x + 9) + 10

y = -4x^2 - 24x -36 + 10

y = -4x^2 -24x -26

Answer:

[tex]47.3\,m[/tex] of garland is required for the length of the ceiling.

Step-by-step explanation:

Width of a rectangle ceiling [tex](w)=42 \,m[/tex]

Diagonal of a rectangle ceiling [tex](d)=70\,m[/tex]

Let [tex]l[/tex] denotes length of a rectangle ceiling.

The relationship between length, width and diagonal of a rectangle is given as follows:

[tex]d^2=l^2+w^2\\70^2=l^2+42^2\\4900=l^2+1764\\l^2=4900-1764\\l^2=2236\\l=47.3\,m[/tex]

So,

[tex]47.3\,m[/tex] of garland is required for the length of the ceiling.

Answer: 7

Step-by-step explanation: use algebra to solve this. 4(x+2)=36

4x+8=36

4x+8-8=36-8

4x=28

x=7

Hope this helps

Answer:

x = 7

Step-by-step explanation:

4(x + 2) = 36

4x + 8 = 36

4x + 8 - 8 = 36 - 8

4x = 28

4x ÷ 4 = 28 ÷ 4

x = 7

Check:

4(x + 2) = 36

4(7 + 2) = 36

4(9) = 36

Solution given;. we have

Tan75=perpendicular /base

base=15/tan75=4.01=4 feet is your answer

Answer: $2.00

Step-by-step explanation:

The best way to do this here is just use quick calculation.

5% of 1 is 0.05. 5% of 2 would be double that, or 0.1.

2.00 - 0.10 is 1.90.

Answer:

The original price was $2.

Step-by-step explanation:

The muffin is on sale for 5% off. This means it is being sold for 95% of its original price.

Its sale price is $1.90. This means that 95% of its original price is 1.90.

Let's set up an equation.

95% of original price is $1.90.

0.95 • x = 1.90

Divide both sides by 0.95 to isolate x.

x = 2

The original price was $2.
