Answer:

d. 5(x + 6) = 47.50

Step-by-step explanation:

First, determine the number of girls; (4 friends + Jacquenline) making a total of 5 girls.

If a ticket costs $6, then the the 5 girls' tickets would cost= 5*6

Also, if a funnel cake costs $x , then 5 girls' cakes would cost= 5* x

Total cost of funnel cake and entry tickets = $47.50

Now make the above three into an equation;

(5*x) + (5*6) = 47.50

5 is the common number on the left side so it becomes;

5( x +6) =47.50

Yes.
4 cups of flour/3 cups of milk= 1.33 flour/milk
2 cups of flour/ 1.5 cups of milk= 1.33 flour/milk
As you can see, these are the same ratios.

Lady bird [3.3K]

Answer:

$23x^{2}$

Step-by-step explanation:

This can be simplified by combing like terms.

8x^2 and 15x^2 are like terms. Since both numbers are positive, we add them together.

The sum of 8x^2 and 15x^2 is 23x^2

I hope this helps.

A sample of marble has a volume of 6 cm3 and a density of 2.76 g/cm3. What is its mass?

Alenkasestr [34]

To solve for the mass of a substance is to simply get the product of volume and density, that is:

mass = density * volume

So calculating for mass:

mass = (2.76 g / cm^3) * 6 cm^3

vladimir2022 [97]

Answer:

Step-by-step explanation:

a). Mean of the given data set = $\frac{32+28+18+40+22}{5}$

= 28

b). x $x-\overline{x}$ $(x-\overline{x})^2$

32 32-28 = 4 16

28 28 - 28 = 0 0

18 18 - 28 = -10 100

40 40 - 28 = 12 144

22 22 - 28 = -6 36

$\sum({x-\overline x})^2$ = 296

c). Standard deviation = $\sqrt{\frac{\sum (x-\overline{x})^2}{n}}$

= $\sqrt{\frac{296}{5} }$

= 7.69

d). Mean of the new set of weights = $\frac{32+33+34+35+36}{5}$

= 34

Since mean of the data set is more close to each data, standard deviation will be less than the deviation given in part (c).
