Answer:

21 feet

Step-by-step explanation:

12^2+x^2=20^2(Pythagorean theorem)

144+x^2=400

x^2=400-144

x^2=256

x=sqrt 256

x=16

y^2+12^2=13^2(Pythagorean theorem)

y^2+144=169

y^2=169-144

y^2=25

y=sqrt 25

y=5

distance between A and B=16+5

=21 feet

Answer:

C)  1340 days

Step-by-step explanation:

The composite function you have given is incorrect.

The composite function for this question is:

t(d) = 60d + 20

(as I have proven in a previous question)

Substitute d = 22 into the function:

t(22) = 60(22) + 20

        = 1320 + 20

        = 1340 days

The population in the study are the people that are 71 years of age and older in the United States.

Population simply means the representative sample of a larger group. Here, the population in the study are the people that are 71 years of age and older.

Also, 0.097 is a statistic because it describes the proportion of the people that suffer from the disease for the sample of 856.

The technical conditions are that the sample should be collected from a normal distribution. In this case, since the sample size is large, then the sampling distribution of the sample means is normal.

Answer:

$40.80

Step-by-step explanation:

First, convert the 20% to an actual number that can be used in a calculation. For percent, this is always done by simply dividing the percent, in this case, 20%, by 100%. So, the conversational term "20%" becomes 20% / 100% = 0.20 in terms of a real mathematical number.

Second, you need to find out what 20% of your $34.00 meal cost is. This is always done by multiplying 0.20 by $34.00, or 0.20 x $34.00=$6.80. So, the amount of tip you are going to leave is $6.80.

This makes the total cost of your meal (to write on your charge slip or other payment)

$34.00 + $6.80 = $40.80.

Answer:

$40.80

Step-by-step explanation:

If you pay for the original cost of the dinner AND leave a 20% tip then the total amount paid will be 120% of the original cost (100% + 20% = 120%).

Convert 120% into a decimal:  120% = 120/100 = 1.2

So 120% of $34.00 = 1.2 × 34 = $40.80

Veremos que el otro lado  del triangulo debe medir 20 metros.

Sabemos que para un triangulo rectangulo de catetos P y K, el area es:

A = P*K/2

En este caso, sabemos que el menor de los catetos mide 5 metros, entonces tenemos:

P = 5m

Y tambien sabemos que el area es de 50m^2, reemplazando eso en la ecuación de arriba obtenemos:

50m^2 = 5m*K/2

Ahora podemos resolver esto para K

(50m^2)/5m = K/2

10m = K/2

2*10m = K = 20m

El otro lado debe medir 20 metros.

Answer:

y=-5x+35

Step-by-step explanation:

Use the formula y = mx + b

m = slope, so plug in -5 as the slope

To find x-intercept we set y=0

We want the x-intercept to be 7 so we can plug that into the equation too

0=-5(7)+b

Lastly solve for b and you get your answer

Which is y=-5x-35 :) hope this helps
