What is 15% of 20? *

Step-by-step explanation:

m(x + n) = n

mx + mn = n

mx = n - mn

x = (n - mn)/m

x(a + b) = b(c - x)

ax + bx = bc - bx

ax + bx + bx = bc

x(a + b + b) = bc

x(a + 2b) = bc

x = bc/(a + 2b)

mx = n(m + x)

mx = mn+ nx

mx - nx = mn

x(m - n) = mn

x = mn/(m-n)

Step-by-step explanation:

Answer:

The new interest rate is about 0.1038.

As a percent, this is about 10.4%.

Step-by-step explanation:

We are given:

[tex]\displaystyle A=250(1.1)^t[/tex]

From this, we can determine that the interest rate is compounded annually at 10%.

We want a new equation that keeps A and P but the interest rate is compounded quarterly.

Compound interest is given by:

[tex]\displaystyle A=P(1+\frac{r}{n})^{nt}[/tex]

Since we are compounding quarterly, n = 4. Since the rate is 10%, r = 0.1. P stays at 250. Therefore:

[tex]\displaystyle A=250(1+\frac{0.1}{4})^{4t}[/tex]

Add:

[tex]\displaystyle A=250(1.025)^{4t}[/tex]

Rewrite:

[tex]A=250((1.025)^4)^t[/tex]

So:

[tex]A\approx 250(1.1038)^t[/tex]

Therefore, the approximate new interest rate is 1.1038 - 1 or about 0.1038.

As a percent, this will be 0.1038 or about 10.4%.

Answer:

21.4% of 855=182.97

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 855 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 855 is 100%, so we can write it down as 855=100%.

4. We know, that x is 21.4% of the output value, so we can write it down as x=21.4%.

5. Now we have two simple equations:

1) 855=100%

2) x=21.4%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

855/x=100%/21.4%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 21.4% of 855

855/x=100/21.4

(855/x)*x=(100/21.4)*x       - we multiply both sides of the equation by x

855=4.67289719626*x       - we divide both sides of the equation by (4.67289719626) to get x

855/4.67289719626=x

182.97=x

x=182.97

now we have:

21.4% of 855=182.97

Answer:

[tex]\sqrt{15.25}[/tex]

Step-by-step explanation:

To find the distance, we can use the distance formula:

[tex]d=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}[/tex] when the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]

Plug in the points (-6.25,5) and (-3.75,2)

[tex]d=\sqrt{(-6.25-x_1)^2+(5-y_1)^2}\\d=\sqrt{(-6.25-(-3.75))^2+(5-2)^2}\\d=\sqrt{(-6.25+3.75)^2+(5-2)^2}\\d=\sqrt{(-2.5)^2+(3)^2}\\d=\sqrt{6.25+9}\\d=\sqrt{15.25}[/tex]

Therefore, the distance between the two coordinates is [tex]\sqrt{15.25}[/tex], or approximately 3.91.

Answer:

2.5

Step-by-step explanation:

The computation of the XW is shown below

As triangle UVX is a right angle

So

VU^2 = XU^2 - VX^2

VU^2 = 15.7^2 - 8.5^2

VU^2 = 246.49 - 72.25

VU^2 = 174.24

VU = 13.2

As VU = WX because of same point tangent

NOw XW is

= UX - UW

= 15.7 - 13.2

= 2.5

Answer: see below

Step-by-step explanation:

Just apply Proportionality Theorem at correct time, with correct proportions, It tells, the ratio of two corresponding arms always equal.

So, 1) AB/BC = AJ/JI

2.5/2.25 = AJ/1.8

AJ = 2.5* 1.8 / 2.25

AJ = 2

2) BC/CD = JI / IH

2.25/CD = 1.8/1.2

CD = 2.25 * 1.2 / 1.8

CD = 1.5

3) CD/DE = IH/HG

1.5/3.5 = 1.2 / HG

HG = 1.2 * 3.5 / 1.5

HG = 2.8

4) For GF, we should use "Pythagoras Theorem"

h² = a² + b²

GF² = 6.5² - 6²

GF² = 42.25 - 36

GF = √6.25

GF = 2.5

5) Perimeter = 2.5 + 2.25 + 1.5 + 3.5 + 6.5 + 2.5 + 2.8 + 1.2 + 1.8 + 2

P = 26.55

6) Area = 1/2 * b * h

A = 1/2 * 9.65 * 10.3

A = 49.70

Answer: 24 raisins

Step-by-step explanation:

30% of the mixture are raisins which means that 70% are peanuts.

That 70% translates to 56 peanuts.

The total of the mixture is therefore:

= 56 / 70%

= 80 mixture of raisins and peanuts

Raisins are 30%:

= 30% * 80

= 24 raisins

3m+6=24

3m=18

m=6

So mike traveled 6 miles by taxi.

We know that the taxi driver chargers $3 per mile, so we say M is the mile variable, and for every M there is $3. So 3m+6 (initial fee) is the first part of the formula.

We set 3m+6=24 (24 being the total amount the taxi driver is charging)
