how do you simplify 50 1/2 + -12.3
Answer:
I believe you divide it
Step-by-step explanation:
hope this helps u
Answer:
38.2
Step-by-step explanation:
50 1/2=50.5 1/2=.5
50.5 + -12.3 is the same as 50.5 - 12.3
50.5 + -12.3= 38.2
50.5 - 12.3 = 38.2

Una caja de 30 kg esta apoyada sobre una de sus caras que tiene 40 cm de ancho y 50 cm de largo. La presion que ejerce sobre el suelo sera
Answer:
294N
Step-by-step explanation:
La presion que ejerce sobre el suelo seria la fuerza de la caja contra el suelo. Esto se calcula multiplicando el peso de la caja por el valor de la gravedad de nuestra tierra. En esta situacion no se necesitaria las dimensiones de la caja.
Fuerza = 30kg * 9.8[tex]m/s^{2}[/tex]
Fuerza = 294N
Fuerza tiene un simbolo de N que significa Newtons que serian calculados como kg * m/s^{2} ... entonces la caja ejerce una fuerza de 294N sobre el suelo.

19. passes through (1, 4) and (-1, 1)
Answer:
y = 3/2x + 2.5
Step-by-step explanation:
Use this formula to find the slope. y2-y2/x2-x1
Plug in
1-4/-1-1= -3/-2 = 3/2
So the slope is 3/2
To find the y-intercept use one of the points you were given. (1,4)
Plug in (1,4)
4 = 3/2(1) + b (b is the y-intercept)
4 = 3/2 + b (minus 3/2 on both sides)
2.5 = b or 5/2 = b
y = 3/2x + 2.5
Of 1000 randomly selected cases of lung cancer, 838 resulted in death within 10 years. Construct a 95% two-sided confidence interval on the death rate from lung cancer. (a) Construct a 95% two-sided confidence interval on the death rate from lung cancer. Round your answers to 3 decimal places. (b) Using the point estimate of p obtained from the preliminary sample, what sample size is needed to be 95% confident that the error in estimating the true value of p is less than 0.03
Answer:
0.8152 ≤ p ≤ 0.8608
579
Step-by-step explanation:
Given the following :
Samples size n = 1000
Deaths within 10 years, p = 838
α = 95%
Construction a two way confidence interval:
p ± Zα/2 * √p(1-p) / n
point estimate p = 838/n = 838/1000 = 0.838
Z0.05/2 = Z0.025 = 1.96
0.838 - 1.96√0.838(1-0.838) / 1000
0.838 - 1.96*0.0116514 = 0.8152
0.838 + 1.96√0.838(1-0.838) / 1000
0.838 + 1.96*0.0116514 = 0.8608
0.8152 ≤ p ≤ 0.8608
b) Using the point estimate of p obtained from the preliminary sample, what sample size is needed to be 95% confident that the error in estimating the true value of p is less than 0.03
Error (E) = 0.03
To find the samome size, use the relation:
n = (Zα/2 / E)² * p(1-p)
n = (1.96/0.03)² * 0.838(1-0.838)
n = (1.96/0.03)² * 0.838 * 0.162
n = 4268.4444 * 0.838 * 0.162
n = 579.46
n = 579

Answer:
80 gallons
Step-by-step explanation:
First to find this, we must divide 10 by 4, and yes I know this will give us a decimal, but it must be done. This division will give us 2.5, we must then multiply 2.5 by 32, as we are given 32 gallons for 4 loads of dishes, and if 2.5 times 4 loads is 10 loads, then we must multiply 32 by 2.5 as well, giving us the answer, 80 gallons
Answer:
80 gallons
Step-by-step explanation:
The answer is 80 gallons when using the distributive, and communitive property of multiplication and division.

If It rained for 9.5 hours, how many inches of rain would have fallen?
Answer:
I believe the answer is 6.5 inches of rain
Step-by-step explanation:
6.33 (with 3 repeating forever) OR 6 [tex]\frac{1}{3}[/tex]
If it was 4 inches after 6 hours lets make an equation. h being the number of hours and i being the inches of rain.
[tex]\frac{4}{6}[/tex]xh = i
Now fill it in with what we know
[tex]\frac{4}{6}[/tex]x9.5 = i
Now solve it.
You get:
6.33 (with 3 repeating forever) OR 6 [tex]\frac{1}{3}[/tex]

Tom drove 504 miles in 8 hours. At the same rate, how many miles would he drive in 12 hours
Answer:
756 miles in 12 hours
Step-by-step explanation:
504÷8=63
63 miles per hour
63×12=756
9514 1404 393
Answer:
756
Step-by-step explanation:
If you recognize that 12 (=8 +8/2) is half-again as much as 8, then you would know that Tom would drive half-again as much as 504 miles. That is, he would drive 504 +504/2 = 504+252 = 756 miles in 12 hours.
__
Since the rate is constant, you can write a proportion:
d/12 = 504/8 = distance/time
d = (12/8)(504) 1.5×504 = 756
Tom would drive 756 miles in 12 hours at that rate.
7 days left until launch of products with $668 left in budget. Need to spend $85 on last day. How many dollars do we spend on remaining days?
Answer:
In total, you have $668.00.
To reserve enough for the last day, you need to subtract the last day's budget:
This means that, for the remaining 6 days in the week, you have $583.00.
Assuming an equal amount is being spent each day, you can calculate the daily budget by dividing the remaining total by the number of days left.
To avoid going over budget, you can spend $97.16 per day for the other six days.
Hope this helps!
