Answer: 6x + 8y =1,245

Step-by-step explanation:

Hi, to answer this question we have to write an equation for each person:

Jack = The total cost (650) must be equal to the product of the number of shirts he bought (2) and the price per shirt (x); plus the product of the number of pair of jeans he bought (5) and the price per jean (y).

2 x+ 5 y=650

Dylan = The total cost (595) must be equal to the product of the number of shirts he bought (4) and the price per shirt (x); plus the product of the number of pair of jeans he bought (3) and the price per jean (y).

4x+3y = 595

Vertical addition:

2 x+ 5 y=650

+

4x+3y = 595

_________

6x + 8y =1,245

Ymorist [56]

Tina increased 40% time from Tuesday to Thursday

Step-by-step explanation:

The percent increase is given by:

$Percent\ increase = \frac{Increase}{Initial\ Value}*100$

Where

$Increase = Current\ value- initial\ value$

Here given

Increase = 10 minutes

Initial value = 25 minutes

So the percentage increase will be:

$Percent\ increase = \frac{10}{25}*100\\= 0.4*100\\=40\%$

Tina increased 40% time from Tuesday to Thursday

Sonja [21]

Answer:

The height of the painting is 28.7525 in and the width is 23.7425 in

Step-by-step explanation:

Let

x -----> the height of the painting

y -----> the width of the painting

we know that

The perimeter of the painting is

$P=2(x+y)\\P=104.99\ in$

so

$104.99=2(x+y)$ ----> equation A

$x=y+5.01$ ----> equation B

substitute equation B in equation A and solve for y

$104.99=2(y+5.01+y)$

$52.495=2y+5.01$

$2y=52.495-5.01$

$y=23.7425\ in$

Find the value of x

$x=23.7425+5.01=28.7525\ in$

therefore

The height of the painting is 28.7525 in and the width is 23.7425 in

Find the missing measure for the cone. Round your answer to the nearest tenth. Use 3.14 for π.

astra-53 [7]

Answer:

h = 3 cm

Step-by-step explanation:

Given that,

Diameter, d = 6 cm

Radius, r = 3 cm

Volume of the cone, V = 28.26 cm³

The formula for the volume of a cone is given by :

$V=\dfrac{1}{3}\pi r^2 h\\\\h=\dfrac{3V}{\pi r^2}\\\\h=\dfrac{3\times 28.26}{3.14\times 3^2}\\\\h=3\ cm$

So, the height of the cone is equal to 3 cm.
