Here is a formula 5t+3=4w(t+2) rearrange the formula to make t the subject

Answers

Answer: [tex]t=\frac{8w-3}{-4w+5}[/tex]

Step-by-step explanation:

Ok let's solve for t

[tex]5t+3=4w(t+2)\\[/tex]

First let's use the distributive property

[tex]5t+3=(4w)(t)=(4w)(2)\\5t+3=4tw+8w[/tex]

Now let's subtract 4tw to both sides

[tex]5t+3-4tw=4tw+8w-4tw\\-4tw+5t+3=8w[/tex]

Next we'll subtract 3 on both sides

[tex]-4tw+5t+3-3=8w-3\\-4tw+5t=8w-3[/tex]

We can now factor out the variable t

[tex]t(-4w+5)=8w-3[/tex]

Now we can divide both sides by -4w+5 giving us our answer

[tex]\frac{t(-4w+5)}{-4w+5} =\frac{8w-3}{-4w+5} \\t=\frac{8w-3}{-4w+5}[/tex]

How many four digit numbers cannot be divided by 5?

Answers

Answer:

7200

Step-by-step explanation:

Since the first digit cannot be zero,

there are 9*10*10*10 = 9000 4-digit numbers.

Each of these with a last digit not equal 5 or 0 is not divisible by 5.

Therefore, there are 8 choices of last digit

9*10*10*8  = 7200

Answer:

y = 6·sin(3·(x - 1)) + c

Step-by-step explanation:

The general form of an equation for a sinusoidal function is presented ad follows;

y = a·sin(b·(x - h) + c

Where;

a = The amplitude of the equation

T = The period = 2·π/b

h = The phase shift

c = The vertical shift

From the question, we have;

a = 6,

2·π/3 = 2·π/b

∴ b = 3

The sum of two smaller sides must be larger than the largest side in order to be a triangle. This means that only the first one can be a set of the triangle.

Find measure of angles B, E, D and C and the length of BC.

Triangle ABC ~ Triangle DEF. Measure of angle A = 30 degrees and measure of angle F = 65 degrees. AB=20, DE = 35, EF= 28.

Answers

Answer:

< B = 180-30-65=85°

< E = 85°

< D = 30°

< C = 65°

BC = 20/35 × 28 = 16

Answer:

<D = 30

< C = 65

<B = <E = 85

16 = BC

Step-by-step explanation:

ABC ~ Triangle DEF

<A = <D = 30

< C = <F = 65

Since they are similar triangles

A+ C + B = 180 since the angles of a triangle = 180

30+65+B =180

95+ B = 180

<B = 180 -95 = 85

<B = <E = 85

The triangles are similar so the sides are proportional

AB      BC

----  = ---------

DE      EF

20      BC

----  = ---------

35      28

Using cross products

20*28 = 35 BC

Divide each side by 35

20*28/35 = 35/35 BC

16 = BC

Answers

Answer:

1520.53

Step-by-step explanation:

The volume of a cylinder is V = pi r^2 h

So you put 16 as the h and half of 11 because 11 is the diameter as r.

V= pi (5.5)^2 * 16

We can also approximate pi and put 3.1415

V= 3.1415 * (5.5)^2 * 16

V = 3.1415 * 30.25 * 16

V= 1520.486

And that is closest to the 3rd option 1520. 53 so that's the answer.

What is the average rate of change for this exponential function for the interval from x = 2 to x = 4?

Answers

Answer:

The average rate of change over the interval is 120

Step-by-step explanation:

For a function f(x) the average rate of change over an interval [a,b] is given as;

f(b)-f(a)/b-a

in this case, a is 2 and b is 4

f(b) is 256 and f(a) is 16

Substituting these values in the equation for rate of change, we have;

(256-16)/(4-2) = 240/2 = 120

what is 9/7 - 1/6= answer ​

Answers

Answer:

tht's just the answer

Step-by-step explanation:

9/7 is equal to 54/42 and 1/6 is equal to 7/42

54/42 - 7/42 is equal to 47/42

Answer:

47/42

Step-by-step explanation:

First, we make both fractions have the same denominator. The LCM of 6 and 7 is 42.

9/7 * 6/6 = 54/42

1/6 * 7/7 = 7/42

54/42 - 7/42 = 47/42

Square A is a scaled version of square B. The dimensions of square A are three times the dimensions of square B. The area of square A is 900 sq cm.

Answers

Answer:

The side of square A is 30 cm.

Step-by-step explanation:

Given that,

The dimensions of square A are three times the dimensions of square B.

The area of square A is 900 sq cm.

Side of square A = 3( side of square B)

Let the side of square B is b. So,

Side of square A, a = 3b

We know that, the area of square is side². So,

[tex](3b)^2=900\\\\9b^2=900\\\\b^2=100\\\\b=10\ cm[/tex]

Side of square A, a = 3(10) = 30 cm

Hence, the side of square A is 30 cm.
