translate the sentence into a equation using n as the unknown number . Then solve the equation for n . 5 increased by half a number is 11

Answers

Answer:

I think it'll be 5 + n = 11

11 - 5 = 6

n = 6

Answer:

Below in bold.

Step-by-step explanation:

Let the number be n, then:

5 + 1/2n = 11

1/2n = 11 - 5

1/2n = 6

Multiply both sides of the equation by 2:

n = 12.

The swimming club need to raise £135 for transport to the swimming gala.

They buy 20 tracksuits for £15.98 each and will sell them to raise money.

What percentage profit should they add to the cost of the tracksuits to raise the £135 they need?

Answers

Answer:

Step-by-step explanation:

The investment was

20(£15.98) = £319.60

After the sale, they want to have

£319.60 + £135.00 = £454.60

Which means each suit sells for

£454.60/20 = £22.73

The markup was

£22.73 - £20.00 = £2.73

which as a fraction of the purchase price is

£2.73/£20.00 = 0.1365

0.1365(100) = 13.65%

Given: f(x)= 3x-7 for x>0
f(x)=-2x+3 for x<0

Find: f(6)

Answers:
11
-9
-3
-18​

Answers

Given :

f(x) = 3x-7 , when x>0

and f(x) = -2x+3 x<0

as 6 is greater than 0, we get that :

f(6) = 3(6)-7

=> f(6) = 18-7

=> f(6) = 11

hence, option a) is correct

The value of f(6) is 11 using the equation f(x)= 3x-7.

To find the value of f(6), we need to determine which condition applies to x = 6. Since x = 6 is greater than 0, we will use the equation f(x) = 3x - 7.

Substituting x = 6 into the equation:

f(6) = 3(6) - 7

f(6) = 18 - 7

f(6) = 11

Therefore, the value of f(6) is 11.

A 16" × 16" square tray can hold at most 9 bagels placed side by side, as shown below. At most how many bagels can a 32" × 32" square tray hold if bagels are placed side by side?\

Answers

Answer:

At most it can hold 18 bagels

Step-by-step explanation:

So we can make this an equation

16 · 16 square tray = 9 bagels on top of it

We just doubled both sides of it

giving us 32 · 32 square tray = 18 bagels can be held.

Step-by-step explanation:

The length of the side opposite to theta:

= √(24^2-21^2)

=  √(24-21)(24+21)

= √(135)

= 3√15.

sin theta = 3√15/ 24 = √15/8.   csc theta = 1/√15/8 = 8/√15 =  8√15/15.

cos theta = 21/ 24 = 7/8.            sec theta = 8/7.

tan theta = 3√15/21 = √15/7.     cot theta = 7/√15  = 7√15/15.

Answers

By definition of the [tex]\ell_p[/tex] norm,

[tex]\|x-y\|_1 = \displaystyle \sum_{i=1}^3 |x_i-y_i| = |5-3|+|2-3|+|4-2| = \boxed{5}[/tex]

[tex]\|x-y\|_2 = \displaystyle \left(\sum_{i=1}^3 |x_i-y_i|^2\right)^{\frac12}= \sqrt{|5-3|^2+|2-3|^2+|4-2|^2}= \sqrt9= \boxed{3}[/tex]

[tex]\|x-y\|_\infty = \max\limits_{i} |x_i-y_i| = \max\left\{|5-3|,|2-3|,|4-2|\right\}=\boxed{2}[/tex]

and so x and y are closest together with p = infinity and furthest apart with p = 1.
