Alis needs 10 strips of ribbon each 2 and 1/2 feet. how much ribbon in all is needed

Answer:

35

Step-by-step explanation:

Please look at the attachment down below.

Hope this helped! :)

The  sum of three number is 35.

A square number is the result when a number has been multiplied by itself.

For example, 25 is a square number because it's 5 lots of 5, or 5 x 5.

Given:

if the number given is 9

9² - (9 - 1)² = 9² - 8²

                 = 81-64

                  = 17.

if the number given is 6.

6² - (6 - 1)² = 6² - 5²

                 = 36-25

                 = 11.

if the number given is 4.

4² - (4 - 1)²= 4² - 3²

                = 16-9

                = 7.

Thus, the sum of three number is

=17 + 11 + 7

= 35

Answer:

y- intercept = 30

Step-by-step explanation:

The y- intercept is the value on the y- axis (vertical) where the graph crosses

Each square on the vertical has a value of 10

The graph crosses the vertical axis 2 squares below 50.

Then y- intercept = 30

Given:

A model of a famous statue is [tex]3\dfrac{1}{2}[/tex] inches tall. The actual statue is [tex]5\dfrac{1}{4}[/tex] feet tall.

To find:

The the ratio of the height of the model to the height of the actual statue in simplest form.

Solution:

We have,

Height of the model = [tex]3\dfrac{1}{2}[/tex] inches

Height of the actual statue = [tex]5\dfrac{1}{4}[/tex] feet.

Now, the ratio of the height of the model to the height of the actual statue is:

[tex]\text{Ratio}=\dfrac{\text{Height of model}}{\text{Height of actual statue}}[/tex]

[tex]\text{Ratio}=\dfrac{3\dfrac{1}{2}\ in.}{5\dfrac{1}{4}\ ft}[/tex]

[tex]\text{Ratio}=\dfrac{\dfrac{3(2)+1}{2}\ in.}{\dfrac{5(4)+1}{4}\ ft}[/tex]

[tex]\text{Ratio}=\dfrac{\dfrac{7}{2}\ in.}{\dfrac{21}{4}\ ft}[/tex]

We know that 1 ft = 12 in.

[tex]\text{Ratio}=\dfrac{\dfrac{7}{2}\ in.}{\dfrac{21}{4}\times 12\ in.}[/tex]

[tex]\text{Ratio}=\dfrac{\dfrac{7}{2}\ in.}{21\times 3\ in.}[/tex]

[tex]\text{Ratio}=\dfrac{7}{2\times 21\times 3}[/tex]

[tex]\text{Ratio}=\dfrac{1}{2\times 3\times 3}[/tex]

[tex]\text{Ratio}=\dfrac{1}{18}[/tex]

Therefore, the ratio of the height of the model to the height of the actual statue in simplest form is [tex]\dfrac{1}{18}[/tex].

Answer: 710,000 kg

Step-by-step explanation:

There are 100 pence in one pound.

The number of two pence coins in 1 pound is therefore:

= 100 / 2

= 50 coins

In 2 million pounds therefore, there will be:

= 50 * 2,000,000

= 100,000,000 two pence coins

If one coin weighs 7.1g, weight is:

= 100,000,000 * 7.1

= 710,000,000 g

A kg is 1,000 grams so the weight in kg is:

= 710,000,000/1,000

= 710,000 kg

Hey there!

The answer to your question is infinitely many solutions.

First, we will simplify each side of the equation. On the left side, we are given:

[tex]2(x+5)+2[/tex]

First, distribute [tex]2[/tex]:

[tex]2x+10+2[/tex]

Add [tex]10[/tex] and [tex]2[/tex]:

[tex]2x +12[/tex]

On the right side, we are given:

[tex]4x+12-2x[/tex]

So, we subtract [tex]2x[/tex] from [tex]4x[/tex]:

[tex]2x+12[/tex]

Now, we have:

[tex]2x+12=2x+12[/tex]

First, subtract [tex]2x[/tex] from both sides:

[tex]12=12[/tex]

We got, [tex]12=12[/tex], which means [tex]x[/tex] has infinitely many solutions.

Answer: 4x+8<120

x<28

Step-by-step explanation:

As per the statement in the question, the inequality will be 4x + 8 < 136.

Inequalities are mathematical expressions where neither side is equal. In inequality, as opposed to equations, we compare the two values. Less than (or less than and equal to), larger than (or greater or equal to), or not similar to signs are used in place of the equal sign in between.

As per the instructions given in the question,

The length (l) of the rectangle = x+4

The width (w) of the rectangle = x

As per the formula of the perimeter, P:

P = 2 (l + w)   (i)

Put the values in (i)

P = 2 (x + 4 + x)

P = 2x + 8 + 2x

P = 4x + 8

Then the inequality as per the statement in the question will be,

4x + 8 < 136.

to solve first divide the total perimiter (40cm)  by 4

this would allow 10cm for each side to allow the longer side to be 2 cm longer than the height we must subtract 1cm (for a total of 2cm) from each side of the rectangle, this would result in the shorter side having a length of 9cm
