Hey there! I'm happy to help!

If something is 11 less, we are subtracting 11.

-11

We have 11 less than seven times a number x.

7x-11

The word is means equals.

7x-11=-4

Now we need to isolate the x. We add 11 to both sides.

7x=7

We divide both sides by 7.

x=1.

Have a wonderful day! :D

Answer: [tex]P=2000(1.04)^t[/tex].

Step-by-step explanation:

It is given that,

Initial population of a town = 2000

Growth rate = 4% = 0.04 per year

The exponential growth function for population is

[tex]P=P_0(1+r)^t[/tex]

where, [tex]P_0[/tex] is initial population, r is growth rate and t is number of years.

Substitute [tex]P_0=2000,r=0.04[/tex] in the above equation.

[tex]P=2000(1+0.04)^t[/tex]

[tex]P=2000(1.04)^t[/tex]

Therefore, the required equation is [tex]P=2000(1.04)^t[/tex], where P is population after t years.

Answer:

74°F

Step-by-step explanation:

In order to find the average of a certain amount of numbers, you add those numbers together and divide by how many numbers there are. In this case, you would reverse that method to find the last number. We know that there were four readings, and we have three of them and the average. Multiply the average (84.75) by the number of readings (4), and you get the sum of all the readings (339). Then you subtract each of the readings that you already know to isolate the last reading. 339 - 112 (first reading) = 227, 227 - 68 (second reading) = 159, and 159 - 85 (fourth reading) = 74. Therefore, the third reading must be 74.

Answer:

The equation of the line is:

[tex]y = -4\,x +16[/tex]

Step-by-step explanation:

A line perpendicular to the given one is going to have a slope equal to the opposite of the reciprocal of 1/4. That is the slope of the new line will be "-4".

Now we write the point-slope form for a line using the info provided of slope -4 and point (5, -4):

[tex]y-y_0=m\,(x-x_0)\\y - (-4) = -4 \,(x-5)\\y+4 = -4\,x +20\\y = -4\,x +16[/tex]

Answer:

y = -4x + 16

Step-by-step explanation:

For questions like this, I would first find the slope of the line that we are trying to find the equation for. To do this, I would use the line y = 1/4x - 2 and find the slope of a line that would be perpendicular to it. Taking the negative reciprocal of the slope of y = 1/4x - 2 will do just that.

By looking at the equation y = 1/4x - 2, we can see that the slope of the line is 1/4. The negative reciprocal of 1/4 would be -4, which would be the slope of the line whose equation we are trying to find.

Since we have a point on the line, and we now have the slope of the line, we can now make an equation for the line in point-slope form:

y + 4 = -4(x - 5)

Now while this is an equation for the line, lets try to get it into slope-intercept form:

y + 4 = -4(x - 5)

Distribute the -4 on the right side of the equation.

y + 4 = -4x + 20

Subtract 4 from both sides.

y = -4x + 16

And now we have the equation of the line in slope-intercept form.

I hope you find my answer helpful.

[tex] \boxed{\sf Height \ of \ parallelogram \ (h) = 8.4 \ cm} [/tex]

Given:

Area of parallelogram (A) = 31.5 cm²

Base of parallelogram (b) = 3.75 cm

To Find:

Height of parallelogram (h)

Step-by-step explanation:

Area of parallelogram (A) = Base (b) × Height (h)

31.5 = 3.75 × h

h × 3.75 = 31.5

h = [tex] \sf \dfrac{31.5}{3.75} [/tex]

h = 8.4 cm

The height of the parallelogram is 8.4cm with a base of 3.75cm and an area of 31.5 sq cm.

A basic quadrilateral with two sets of parallel sides is known as a parallelogram. In a parallelogram, the opposing or confronting sides are of equal length, and the opposing angles are of equal size.

The area of a parallelogram is base multiples by height as two triangles form a parallelogram.

Given, The area of the parallelogram is 31.5 sq cm and the base is 3.75 cm.

We know the area of a parallelogram is base×height.

∴ h×3.75 = 31.5.

h = (31.5/3.75) cm.

h = 8.4 cm.

Answer:

Coffee= $4

Tea= 3.50

6x4=$24

so with this in mind you must take 24 and divide it by the price of tea

24/3.50 is 6.8 so they max cups of tea he can buy is 6.

Hope this helps. :)

Step-by-step explanation:

The maximum number of cups he can buy will be 7.

Expression in maths is defined as the collection of numbers variables and functions by using signs like addition, subtraction, multiplication, and division.

Numbers (constants), variables, operations, functions, brackets, punctuation, and grouping can all be represented by mathematical symbols, which can also be used to indicate the logical syntax's order of operations and other features.

Given that a cup of coffee costs $4 and a cup of tea costs $3.50. If ray has $40 and has bought 6 cups of coffee.

6x4=$24

Divide 24 by 3.50 to get the number of cups.

24/3.50= 6.8

Therefore, the maximum number of cups he can buy will be 7.

Step-by-step explanation:

The sum of Mia's three highest salaries is ...

  $92,000 +94,800 +96,250 = $283,050

so the average is ...

  $283,050/3 = $94,350

Her pension is then ...

  0.01875 × $94,350 = $1769.06

Additional comment

This is equivalent to the total of those salaries, divided by 160.

  T/3 × 0.01875 = T × (0.01875/3) = T × 0.00625 = T/160
