Answer:

A. 34in

Step-by-step explanation:

If James completely covered a square poster board using 68.2 inches with an exponent of 2, the the total perimeter of the square will be;

P = 2(68.2) = 136.4in

Since the perimeter of a square is expressed as:

P = 4L

136.4 = 4L

L = 136.4/4

L = 34.1in

Hence the measurement of one side of the square poster is closest to 34in

Charlie paid 660 for 6 shirts and four belts. One shirt costs three times as much as one belt. If Sam bought 5 shirts and 2 suck

Cerrena [4.2K]

Sam would have to pay $510 to buy 5 shirts and 2 suck belts.

Step-by-step explanation:

Let,

Cost of one shirt = x

Cost of one belt = y

According to given statement;

6x+4y = 660 Eqn 1

x = 3y Eqn 2

Putting value of x from Eqn 2 in Eqn 1

$6(3y)+4y=660\\18y+4y=660\\22y=660$

Dividing both sides by 22

$\frac{22y}{22}=\frac{660}{22}\\y=30$

Putting y=30 in Eqn 2

$x=3(30)\\x=90$

One shirt costs $90 and one belt cost $30.

Price of 5 shirts = 90*5 = $450

Price of 2 belts = 30*2 = $60

Total = 450+60 = $510

Sam would have to pay $510 to buy 5 shirts and 2 suck belts.

If y varies inversely as x, and y = 33 when x = 7, what is the constant and what is value of y when x=11?

kow [346]

Answer:

We have that y = 21 when x = 11.

Step-by-step explanation:

We solve this question by proportions, using a rule of three.

Since they vary inversely, we apply the inverse rule of three, that is, with lateral multiplication instead of diagonal.

33 - 7

y - 11

$11y = 33*7$

Dividing both sides by 11

$y = 3*7 = 21$

We have that y = 21 when x = 11.

What the mean of 65, 50, 44, 86, 90, 50, 35, 110, 70, 50, 35, 60, 56?

$\large\text{Hey there!}$

$\text{Your \boxed{mean} is known as your \boxed{\bf{average}}}$

$\text{The mean/average formula is: \boxed{\rm{\dfrac{sum\ of\ all\ numbers\ in\ the\ data\ plot}{total\ number(s)\ in\ the\ data\ plot} = mean}}}$

$\rm{Equation \rightarrow \dfrac{65 + 50 + 44 + 86 + 90 + 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}}$

$\rm{\dfrac{65 + 50 + 44 + 86 + 90 + 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}}$

$\rm{ = \dfrac{115 + 44 + 86 + 90 + 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}}$

$\rm{= \dfrac{159 + 86 + 90 + 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}}$

$\rm{= \dfrac{245 + 90 + 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{335+ 50 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{385 + 35 + 110 + 70 + 50 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{420 + 110 + 70 + 50 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{530+ 70 + 50 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{600 + 50 + 35 + 60 + 56}{13}$
$\rm{= \dfrac{650 + 35 + 60 + 56}{13}$

$\rm{= \dfrac{685 + 60 + 56}{13}$

$\rm{= \dfrac{745 + 56}{13}$

$\rm{= \dfrac{801}{13}}$

$\rm{= 61.6154}$

$\rm{\approx 62}$

$\huge\text{Therefore, your answer should be:}$

$\huge\boxed{\underline{\underline{\frak{61.6154}}}}\ \huge\boxed{\approx \frak{62}}\huge\checkmark$
