what is the answer to 3?

Answer:

15%

Step-by-step explanation:

Total families:

[tex]45 + 38 + 27 + 10 = 120[/tex]

Difference between the families:

[tex]45 - 27 = 18[/tex]

Percentage calculation:

[tex]\% = \frac{18 \times 100}{120} = 15\%[/tex]

I don't believe it is scalene, maybe try looking it up?

Answer:

NO

Step-by-step explanation:

A scalene triangle has no sides equal. This triangle has two sides equal with 13 inches. This triangle is isosceles.

Answer:

a. 2/3

b. [tex]\sqrt{2}[/tex]

c. 3

d. 5

e. 2

f. Undefined

Step-by-step explanation:

a. [tex]f(x)=\frac{|x-3|}{x+2}[/tex]

To find f(1), plug in 1 where every x is in the equation

[tex]f(1)=\frac{|1-3|}{1+2}=\frac{|-2|}{3}=\frac{2}{3}[/tex]

b. [tex]f(x) = \sqrt{x+1}[/tex]

[tex]f(1) = \sqrt{1+1}=\sqrt{2}[/tex]

c. [tex]f(x) = x^2+5x-3[/tex]

[tex]f(1) = (1)^2+5(1)-3=1+5-3=6-3=3[/tex]

d. [tex]f(x)=\frac{2x+3}{x}[/tex]

[tex]f(1)=\frac{2(1)+3}{1}=\frac{5}{1}=5[/tex]

e. [tex]f(x) = |2x-4|[/tex]

[tex]f(1) = |2(1)-4|=|2-4|=|-2|=2[/tex]

f. [tex]f(x)=\frac{7-2x}{x-1}[/tex]

[tex]f(1)=\frac{7-2(1)}{1-1}=\frac{5}{0}[/tex]

This equation is undefined when x=1 because 0 is the denominator of the fraction.

Answer: A

Step-by-step explanation:

[tex]\frac{6.3\cdot \:10^8}{9\cdot \:10^2}[/tex]

[tex]=\frac{6.3\cdot \:10^6}{9}[/tex] --> Exponent rule for division, 10^8/10^2 = 10^6

= 700,000 --> In scientific notation, 7.0×10^5

Answer:

$272559.70

Step-by-step explanation:

So, let's start with what we know

This problem should be solved with the formula

A = P ( 1 + r/n)^nt

The variable A is the final amount

A = 3000000

This is the amount we want to achieve

The variable P is the principle, the amount of money you put in a bank to earn interest

We have to solve for this value

The variable r is the interest rate

r = 0.065

Note: I converted the percent to a decimal, so we can use it in the formula

The variable n is the amount of times interest is compounded

n = 12

The interest is compounded monthly in a year, so 12 times

The variable t is the amount of time you have to earn the interest

t = 37

So, let's solve for the value P with the values we know

3000000 = P ( 1 + 0.065/12)^(12x37)

3000000 = P(11.0067628047)

3000000 / 11.0067628047 = P(11.0067628047) / 11.0067628047

272559.702905 = P

P = 272559.70

Note: I rounded to the nearest cent, since there isn't a value of USD lower than 1 cent.

So, there you have it, a principle of 272559.70 will get you 3000000 in 37 years given that interest is compounded monthly at 6.5% interest rate

All you need to do is subtract the coefficient.

Step-by-step explanation:

For example a minus b is c. So this is simply going to be c times d to the e you can do that if these two are the same.

Answer:

x = 9

Step-by-step explanation:

2x + 15 = 5x - 12 (since it is parallel)

15 + 12 = 5x - 2x

27 = 3x

x = 9

Answer:

it's 11 and x is 12

Answer:

y = 15

Step-by-step explanation:

since the triangles are similar then the ratios of corresponding sides are in proportion, that is

[tex]\frac{y}{33}[/tex] = [tex]\frac{10}{22}[/tex] ( cross- multiply )

22y = 330 ( divide both sides by 22 )

y = 15

Answer:

(x +2) (x+ 8)

Step-by-step explanation:

2x^2 + 20x + 32

you have to multiply 32 by 2 bc the leading coefficient is >1, now find which multiples of 64 add up to 20, which is 16, and 4

(2x +4) (2x +16)   u have to simplify these bc the leading coefficient is >1, the gcf is 2, so divide by 2

(x + 2) (x + 8)

Answer:

4

Step-by-step explanation:

TW is the midsegment of the trapezoid UVXY

=> 2TW = XY + UV

=> 2(z - 2) = 4z - 34 + z

=> 2z - 4 = 5z - 34

=> 5z - 2z = 34 - 4

=> 3z = 30

=> z = 10

Answer: z = 10

Ok done. Thank to me :>
