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.

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:

In 5 hours, he will go 3 ¾ kilometers far.

Answer:

The size of the larger of the two segments = 6

Step-by-step explanation:

Attached below is the triangle  ( DOG )

perimeter of Triangle = 33

DO = 10

DG = 12

OG = x

formula for perimeter = DO + DG + OG = 33

                                   = 10 + 12 + OG = 33

hence: OG = 33 - ( 10 + 12 ) = 33 - 22 = 11

third side ( x ) = 11

Finally determine the length of the larger of the two segments of side ( OG)

from the diagram below

[tex]\frac{y'}{x'} = \frac{12}{10}[/tex]   -------------------- ( 1 )  

where x' = 11 - y'

hence equation 1 becomes

10y' = 12x'

10y' = 12 ( 11 - y' )

10y' = 132 - 12y'

22y' = 132

∴ y' = 132 / 22 = 6

hence x' = 5

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.

[tex]\frac{8}{3}[/tex] = 2.67

V = 9 x 2.67

Step-by-step explanation:

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:

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

Step-by-step explanation:

The equivalent to the complex number i³² is 1.

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

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

[tex]2 \dfrac25[/tex]

Step-by-step explanation:

The first pipe drains 1/4 of the pool every hour, and the second pipe drains 1/6 of the pool every hour. Combined, they drain [tex]\dfrac14 + \dfrac16 = \dfrac{5}{12}[/tex] of the pool per hour. Therefore, it will take 12/5 hours, or 2 2/5 hours.

(brainliest pls ty)

Both pipe are together then they take 6 hour to fill the pool.

In 1 hour they fill the pool is 110 hours

In 1 hour pipe A can fill the pool = x/1

​In 1 hour pipe B can fill the pool= y/1

​so

4 hours=x/4

6 hours=y/6

If both pipe are together then they take 6 hour to fill the pool.

If the are together then in 1 hour they fill the pool.

x/1 +  y/1 = 6/1+4/1= −−−−(1)

=10 hours

Example:A swimming pool may be filled using two pipes in 12 hours. Only half of the pool can be filled if the larger pipe is utilized for 4 hours and the smaller pipe for 9 hours.

10,000 divided by 240 minutes, or 4 hours, yields approximately 41.6. With the drain blocked, your pool would therefore fill at a rate of about 41 gallons per minute.

However, 'b' is the y axis intercept (the point where is crosses the y axis and 'm' is the slope of the line.  The 'm' and the 'b' can be positive or negative numbers.

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
