Answer:Wednesday

Step-by-step explanation:

Given

Sunday is considered as 0 day and

Monday as day 1 so Saturday must be considered as day 7

At the end of 155 days

i.e. [tex]\dfrac{155}{7}=22\times 7+1[/tex]

Up to  155 days there are 22 weeks and 1 extra day i.e.

There are 22 Mondays plus 1 extra day i.e. Tuesday

[tex]155^{th}\ \text{day is Tuesday and day after it is wednesday}[/tex]

Step-by-step explanation:

So the d in this case is 2. D is the number of kilometers Erica walked.

T is the vertical distance.

Find the right choice:

After she had walked 2km along the trail, Erica's vertical distance from the top of the valley was equal to T kilometers.

Answer: 5%

Step-by-step explanation:

Hi to answer this question, first we have to calculate the discount amount:

Original price - sale price

500-475 =25

Now, the original price (500) multiplied by the percent discount in decimal form (x) must be equal to the discount amount (25)

500x =25

Solving for x

x =25/500 =0.05

Multiply it by 100 to express in percentage form.

0.05 x 100 = 5%

Feel free to ask for more if needed or if you did not understand something.

Answer:

[tex]2^{\frac{11}{2}}[/tex].

Step-by-step explanation:

We need to write the given expression with prime number base.

In question 7, part d.

The given expression is

[tex]8\sqrt{32}[/tex]

It can be rewritten as

[tex]2^3\sqrt{2^5}[/tex]

Using properties of exponents , we get

[tex]2^3(2^5)^{\frac{1}{2}}[/tex]

[tex]2^3(2^{\frac{5}{2}})[/tex]    [tex][\because \sqrt[n]{x}=x^{\frac{1]{n}}][/tex]

[tex]2^{3+\frac{5}{2}}[/tex]    [tex][\because (a^m)^n=a^{mn}][/tex]

[tex]2^{\frac{6+5}{2}}[/tex]    [tex][\because a^ma^n=a^{m+n}][/tex]

[tex]2^{\frac{11}{2}}[/tex]

Here, base is 2 and it is prime number.

Therefore, the required expression is [tex]2^{\frac{11}{2}}[/tex].

Answer:

x(x - 7)(x^3 + 2)

Step-by-step explanation:

Note that x is a common factor here:

3x^5-7x^4+6x^2-14x  =  x(3x^4 - 7x^3 + 6x - 14), or:

x(3x^4 - 7x^3 + 6x - 14)     Note that 6x - 14 can be rewritten as 2[x - 7]

                                          and that 3x^4 - 7x^3 can be rewritten as x^3[x - 7]

Therefore, x(3x^4 - 7x^3 + 6x - 14 becomes:

x(x - 7)(x^3 + 2)

Answer: No they don't because there is not way 1/3 can be multiplied by a number to get  2/9 and there is no way 2/9 can be divide by any number to get 1/3.

Step-by-step explanation:

Answer:

they do!

Step-by-step explanation:

2/9 / 1/3 = 3/6 = 1/3

So the proportion is 2 to 1

Answer:

C = 3 √ 5

(since 9 is a perfect square), we can simplify radical 45 to 3 times radical 5

B √ 9*5 is true but not simplified.

We need to find a square numbers that divide into 45

We find 9

And show a * b = c

c= 45

so a * b = 9 * 5  = 3√ 5 is how we arrange this to simplify.

Step-by-step explanation:

The list is

1, 4, 9, 16, 25, 36, 49, 64, 81, 100

We see there are 10 perfect squares 1-100

5 are 1-25

then think 6 , 7, 6 , 9 ,10 squared/ if you cant list them too quickly.

Answer:

9x-2w+11y

Step-by-step explanation:

To find the perimeter, add up all the sides

7x-7w  + 2x+9y   + 2y+5w

Combine like terms

7x +2x    -7w +5w  + 9y+2y

9x-2w+11y

Answer:

144 cm

Step-by-step explanation:

P=4l

P=4*36

P=144 cm

Answer:

144 cm

Step-by-step explanation:

Since the shape is a square, all the lengths are the same. so to solve, add all the lengths together. Either (36+36+36+36) or 36*4. 36*4=144. So, the answer is 144 cm

Answer:

x = - 4

Step-by-step explanation:

y = - 8 is the equation of a horizontal line parallel to the x- axis.

A perpendicular line must then be a vertical line parallel to the y- axis.

The equation of a vertical line is x = c

where c is the value of the x- coordinates it passes through.

The line passes through (- 4, - 2) with x- coordinate - 4, thus

x = - 4 ← equation of perpendicular line

Answer:

Determine the equation of the line perpendicular to the line y = –8 through the point (–4, –2).The line y = –8 is ✔ horizontalslantedvertical.The line perpendicular to the line y = –8 is horizontalslanted✔ vertical.The equation of the line perpendicular to the line y = –8 through the point (–4, –2) is ✔ x = –4y = –4x = –2y = –2.
