I will REALLY answer your question :)

9.5 = 25/t + -8

The first step here is to simplify t + -8. If you add a negative of  something, you also subtract. This can be rewritten as:

9.5 = 25/t - 8

Now, we need to add 8 to undo the subtraction.

17.5 = 25/t

Now, to undo the division, we will multiply the whole equation by 25.

17.5 x 25 = 437.5

Answer:

[tex]\frac{1}{4}[/tex]

= 0.25

Step-by-step explanation:

In a standard deck of cards, there are 52 cards. The standard deck of cards also has 13 clubs. Probability is;

[tex]\frac{wanted- outcomes}{total- outcomes}[/tex]

The wanted outcomes is a clubs, the total outcomes are the total number of cards in the deck, hence;

[tex]\frac{13}{52}[/tex]

Simplify;

[tex]\frac{1}{4}[/tex]

Answer:

3/14 or about 21%

Step-by-step explanation:

Just divide the number of black cars by the total number of cars.

15/70 = 3/14

Answer:

Area of original = 169m^2

Area of new = 676m^2

Step-by-step explanation:

Area of a square = (length of side)^2

13^2 = 13 * 13 = 169

If the dimension is doubled:

(2*13)^2 = 26^2 = 676

Answer:

20.07 cm³

Step-by-step explanation:

Volume of Cylinder = 1.54 liters = 1540 cm³.

Area of its base = 77 cm².

πr² = 77

(22/7) * r² = 77

r = 4.94

Now,

Volume of cylinder = πr²h

⇒ 1540 =  (22/7) * (4.94)² * h

⇒ h = 20.07 cm³

Tenths are the first place after the decimal point.

Answer:

6.4

Step-by-step explanation:

To do this you just have to multiply 40 by 2 to get 80 and than divide by 12.5 and you get 6.4

Answer:

Step-by-step explanation:

70 - 8,69 - 8,69 - 8,69

You substracted it 3 times which means your answer is 3 pounds

Step-by-step explanation:

100 = 12

300 + 50 = 36 + 6 = 42 L

Answer:

$150 per month

Step-by-step explanation:

If you divided 1800 by 12 you will get 150 so therefore he needs to pay $150 per month.

Answer:

z2 - z1 = 7/3i

Step-by-step explanation:

Given the following complex number:

z1 = 9+i/3i

z2 =  2+i/3i,

Taking the difference

z2 - z1 = 9+i/3i - (2+i))/3i)

z2-z1 = (9+i-(2+i))/31

z2 - z1 = 9+i -2-i/3i

z2-z1 = 9-2/3i

z2 - z1 = 7/3i

Note that the complex number given was not properly written and the ones used were assumed. Same procedure an be used for other complex numbers that might be given.

Soln

given,

from the figure

coordinate of B is (5,3),

A(7,0) and C(0,4)

A. solution

let, M(x,y) be the mid point of AB

A(7,0) = (x1,y1)

B(5,3) = (x2,y2)

we know

x = (x2+x1)/2

or, x = (5+7)/2

or, x = 12/2

or, x = 6

and for y

y = (y2+y1)/2

or, y = (3+0)/2

or, y = 3/2

therefore M(x,y) = (6,3/2)

B. solution

let,

C(0,4) = (x1,y1)

B(5,3) = (x2,y2)

equation of line is ;

(y - y1)/(x - x1) = (y2 - y1)/(x2 - x1)

or, (y - 4)/(x -0) = (3 - 4)/(5 - 0)

or, (y - 4)/(x - 0) = -1 / 5

by cross multiply

or, 5×(y - 4) = -1×(x)

or, 5y - 20 = -x

or, x + 5y = 20 is the required equation.

Answer:

Directions - Identify the key components, create an exponential equation, then answer the questions.  

​Exponential Form:  y=a\cdot b^{x},\ a\ is\ the\ \textit{starting}\ \textit{value},\ b\ is\ the\ base\ (rate).\y=a⋅b  

x

, a is the starting value, b is the base (rate).  

​In a small town, the stray dog population is rapidly increasing. there are currently 15 stray dogs, and it is estimated that the population will triple every year. How many dogs will there be after 1 year? 2 years? 3 years?

​

​1) a =  15  

 4) Dogs after 1 years = 45  

 ​

​2) b =  3  

 ​5) Dogs after 2 years =   135

​3) Equation:    

y= 15 ×3x

Answer:

RT = 20

Step-by-step explanation:

Point S is on line segment

R------------S------------T

RS + ST = RT

Given

ST=3x-8

RT=4x

RS=4x-7,

Step 1

We find x

4x - 7 + 3x - 8 = 4x

4x + 3x -7 - 8 = 4x

7x - 15 = 4x

7x - 4x = 15

3x = 15

x = 15/3

x = 5

Step 2

We find RT

RT = 4x

x = 5

RT = 4 × 5

RT = 20

The numerical length of RT is 20

Answer:

20 percent of them

Answer:

The first number is zero, and the second number is 17

Step-by-step explanation:

If we triple the first number (which is zero), it would still equal zero. Then, if you double the second number the answer would be 34.

Answer:

[tex]P(X=35) =0.2\%[/tex]

Step-by-step explanation:

From the question we are told that

Sample space n = 150

Sample  percentage p = 0.15

Generally people without the disease in the set is give as X

[tex]X= 1-p[/tex]

[tex]X= 0.85[/tex]

35 have kidney disease,

[tex]P(X=35) = C(150,35)*(0.15)^35*(0.85)^115[/tex]

[tex]P(X=35) = 0.0021[/tex]

[tex]P(X=35) =0.2\%[/tex]

Answer:

14.77 feet

Step-by-step explanation:

Using the pythagoras theorem to get the length of the ramp

l² = 13² + 7²

l is the length of the ramp

l² = 169 + 49

l² = 218

l = √218

l = 14.77 feet

Hence the length of the ram is 14.77 feet
