Answer:
2685-279=2,406
2,406÷2=1,203
Step-by-step explanation:
Ricky hit 1,203. because Pedro hit 279 so subtract it from 2685 and then divide by 2 and then you get Ricky's and you also get pedros if you add 1203 and 279 which gives you 1482.

In each of these Law of Sines problems, you are given side a and angles B and C and asked for side c (problems 1, 3, 4) or side b (problem 2). The solution is basically the same for each:
Find the missing angle. Find the side from ...
c = a·sin(C)/sin(A)
__
1. angle A = 180°-89°-58° = 33°
c = (18 m)sin(89°)/sin(33°) ≈ 33.0 m
__
2. angle C = 180°-13°-17° = 150°
b = (58 mi)sin(13°)/sin(150°) ≈ 26.1 mi
__
3. angle A = 180°-61°-89° = 30°
c = (16 mi)sin(61°)/sin(30°) = 28.0 mi
__
4. angle A = 180°-39°-127° = 14°
c = (10 mi)sin(127°)/sin(14°) ≈ 33.0 mi

Step-by-step explanation:
A store sells cashews for $5.00 per pound and peanuts for $1.50 per pound. The manager decides to mix 10 pounds of peanuts with some cashews and sell the mixture for $3.00 per pound. How many pounds of cashews should be mixed with the peanuts so that the mixture will produce the same revenue as would selling the nuts separately?
There should be __ pounds of cashews in the mixture.
(Type an integer or a decimal.)
Answer:
7.5 pounds
Step-by-step explanation:
The computation is shown below:
let us assume x be the pounds of cashews,
and the total pounds will be x + 10
Now the equation is
10($1.5) + x(5.00) = (10 + x)(3.00)
15 + 5x = 30 + 3x
2x = 15
x = 7.5 pounds
A manufacturer of a new nicotine nasal spray claims that their product has a 30% success rate for smoking cessation. In a clinical study involving 150 smokers, 93 of them quit smoking. Test the hypothesis that the success rate claimed by the manufacturer is valid at the 5% level of significance.
answer:
we reject null and conclude that this manufacturers claim is false
Step-by-step explanation:
p = 30% = 0.30
p^ = 93/150 = 0.62
we state the hypothesis
H0: p = 0.30
h1: p not equal to 0.30
we find the z test stattistics
[tex]z=\frac{p^--p}{\sqrt{\frac{p(1-p)}{n} } }[/tex]
[tex]z=\frac{0.62-0.30}{\sqrt{\frac{0.30(1-0.30)}{150} } }[/tex]
[tex]z=\frac{0.32}{\sqrt{\frac{0.30*0.70}{150} } }[/tex]
[tex]z=\frac{0.32}{0.03741}[/tex]
z = 8.5538
at alpha = 0.05
z-critical = Z₀.₀₅/₂ = Z₀.₀₂₅
= 1.96
we compare z critical with the test statistic
z statistic > z critical so we have to reject H₀ and conclude that the manufacturers claim is not valid at 0.05 level of significance.

A bucket that weighs 3 lb and a rope of negligible weight are used to draw water from a well that is 50 ft deep. The bucket is filled with 42 lb of water and is pulled up at a rate of 2.5 ft/s, but water leaks out of a hole in the bucket at a rate of 0.25 lb/s. Find the work done in pulling the bucket to the top of the well. Show how to approximate the required work by a Riemann sum. (Let x be the height in feet above the bottom of the well. Enter xi* as xi.)
Answer:
the work done in pulling the bucket to the top of the well is 2125 ft-lb
Step-by-step explanation:
Given that;
Weight of the bucket is 3 lb
weight of water which can be filled in the bucket is 42 lb
Total weight of bucket and water = 3 + 42 = 45 lb
distance, the bucket filled with water is to be pulled 50 ft
now, let at any time t be the bucket at distance x ft from the bottom of the well
then, t = x/2 × S
where S is the rate at which water is leaking from the bucket
so at this time t, the amount pf water which leaked from the bucket is;
⇒ x ft / 2.5 ft/s × 0.25 lb/s
= 0.25 lb.s⁻¹ / 2.5 ft.s⁻¹ × x ft
= 0.1 lb/ft × x ft
= 0.1x lb
now, as x represent the distance that the bucket has been raised, we the force F applied to the bucket x to be;
F = ( 45 - 0.1x ) lb
so, the required worked by Riemann sum as;
[tex]\lim_{n \to \infty}[/tex]ⁿ∑_[tex]_{i=1}[/tex] ( 45 - 0.1x[tex]_i[/tex]* ) Δx
so, the work done, pulling the bucket up will be;
[tex]\lim_{n \to \infty}[/tex]ⁿ∑_[tex]_{i=1}[/tex] ( 45 - 0.1x[tex]_i[/tex]* ) Δx = [tex]\int\limits^{50}_0 {(45-0.1x)} \, dx[/tex]
= [ 45x - 0.1[tex]\frac{x^2}2}[/tex] ]⁵⁰₀
= 45 × 50 - 0.1/2 × (50)²
= 2250 - 125
= 2125 ft-lb
Therefore, the work done in pulling the bucket to the top of the well is 2125 ft-lb

thank you

Alexis is working for a GPS company. The GPS software has recently been updated with a new algorithm and Alexis needs to
check to see if it is calculating properly. Alexis places Charlotte area on a grid and finds Charlotte to be at (6,7) and Gastonia
is at (-1,4). What is the distance between them, if each unit is two miles?
Answer:
2root(58) == 15.23 miles
Step-by-step explanation:
Find distance between two points --> root( (x2 - x1)^2 + (y2 - y1)^2 ) = root (3^2 + 7^2) = root ( 58), as one unit is two miles then 2* root(58) = 15.23 miles.

Step-by-step explanation:
Hillary works at a video store. she earns $8.50 per hour plus 12% commission on all the weekly sales she makes. If she works 24 hours in a week, which expression best describes her sales (x) if she earns at least $324 during that week
Answer: See explanation
Step-by-step explanation:
Let her sales be represented by x.
Based on the information given in the question, the equation to calculate her sales goes thus:
(8.50 × 24) + (12% × x) ≥ 324
204 + (0.12 × x) ≥ 324
204 + 0.12x ≥ 324
0.12x ≥ 324 - 204
0.12x ≥ 120
x ≥ 120/0.12
x ≥ 1000
Her sales is at least $1000

Anna walks 3 kilometers a day. How many METERS does she walk in 5 days?
Answer:
15000 meters in five days
Step-by-step explanation:
There are 1000 meters in a kilometer.
3 x 1000 = 3000
3000 meters per day
3000 x 5 = 15000
15000 meters for 5 days
Answer:
15km or 15000m
Step-by-step explanation:
We have a speed, which is 3 km a day, and a time which is 5 days.
If speed is equal to distance/time
Distance must equal speed multiplied by time, or 3 times 5.
This gives us 15km
If a kilometer is 1000 meters, then 15km is 15 times 1000, or 15000

Answer: y = (16/3)*x - 13.33
Step-by-step explanation:
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Then for our particular case, we know that the line passes through the points (4, 8) and (1, -8)
Then the slope for this line will be:
a = (8 - (-8))/(4 - 1) = 16/3
Then our line is something like:
y = (16/3)*x + b
We need to find the value of the y-intercept b.
We know that this line passes through the points (4, 8) and (1, -8)
Then we can just replace the values of one of these points in our linear equation, for example, if we se the first one we get:
x = 4 and y = 8
replacing that in our equation we get:
8 = (16/3)*4 + b
8 - (16/3)*4 = b
-13.33 = b
Then the equation for our line is:
y = (16/3)*x - 13.33

Step-by-step explanation:
The equivalent to the complex number i³² is 1.
What is a complex number?A complex number is a component of a number system that includes the imaginary unit, represented by the letter i as an extension of the real numbers.
Given:
i³²
As we know that i² = -1
The i³² can be written as,
(i²)¹⁶
Put the value of i² = -1
(-1)¹⁶
As the power is an even number, so the result will be a positive number,
i³² = (-1)¹⁶ = 1
