Answer:

The rate of the boat is 75.17 km/h and the rate of the stream is 17.83 km/h

Step-by-step explanation:

System of Equations

Let's call:

B = speed (rate) of the boat in still water

S = speed (rate) of the stream

The boat travels 172 km in 3 hours when going upstream, that is when the speed of the stream subtracts its own speed. The speed is the distance divided by the time, thus:

[tex]\displaystyle B-S=\frac{172}{3}[/tex]

Multiplying by 3:

3B - 3S = 172        [1]

The boat travels 372 km in 4 hours downstream when the speed of the current adds to its own:

[tex]\displaystyle B+S=\frac{372}{4}=93[/tex]

B + S = 93

Solving for B:

B = 93 - S       [2]

Substituting in [1]

3(93 - S) - 3S = 172

Operating:

279 - 3S - 3S = 172

279 - 6S = 172

Subtracting 279:

- 6S = 172 - 279

- 6S = -107

Multiplying by -1 and solving for S:

[tex]S = \frac{107}{6}\approx 17.83\ km/h[/tex]

From [2]:

[tex]B = 93 - \frac{107}{6}[/tex]

[tex]B=\frac{451}{6}\approx 75.17\ km/h[/tex]

Answer:

8 percent

27000-25000=2000

do that as a percent

Answer:

C) 30

Step-by-step explanation:

As, angle 8 = 150°

So angle 6 = 30°

As, they are supplementry to each other

Now, Angle 5 + Angle 6 = 180°

So,as angle

So, Angle 5

Angle 5 + 30° = 180°

Angle 5 = 180° - 30°

Angle 5 = 150°

So therefore, Angle 5 = 150°

Answer:

15 feet

Step-by-step explanation:

Use the Pythagorean theorem which is a^2 + b^2 = c^2

a and b represents the legs of the triangle

c represents the hypotenuse (which is the chain)

Answer: 15ft chain length

Step-by-step explanation: A right triangle is formed from the picture. Using pythagorean theoreom

12^2+9^2=c^2

225=c^2

15=c

Answer:

4 gallon = 16 quarts

Step-by-step explanation:

Consider the provided information.

We need to convert gal into qt

We know that 1 gallon = 4 quarts

Now in the given question, we have 4 gal.

Multiply both the sides by 4

1×4 gallon = 4×4 quarts

4 gallon = 16 quarts

Hence, 4 gallon is equal to 16 quarts.

Answer:

2.3 and 1.8

Step-by-step explanation:

Answer:

<ABC = 51°

Step-by-step explanation:

Given

<A = 2x -15°

<B = x - 5°

< C = 148°

Now

<A + <B = < C ( Exterior angle of a triangle is equal to the sum of two opposite interior angles)

2x -15° + x - 5° = 148°

3x - 20° = 148°

3x = 148° +20°

3x = 168°

x = 168° / 3

X = 56°

Now for Angle B

= 56° - 5°

= 51°

Hope it helps :)

Answer:

D

Step-by-step explanation: So, multiplying two rationals is the same as multiplying two such fractions, which will result in another fraction of this same form since integers are closed under multiplication. Thus, multiplying two rational numbers produces another rational number.

Answer:

The product of a rational number and an irrational number is irrational.

Step-by-step explanation:

The product of a rational number and an irrational number is irrational. For example, let p= 1 be a rational number and q= 3.567be an irrational number if multiplied together the result would be 3.567, which is an irrational number.

Answer:

Required two variable relation is 45x =y

Step-by-step explanation:

Speed of isabella car is v = 45 miles per hour

now, According to question she takes Y miles( = distance) in X hours (= time)

from The relation of velocity i.e.

velocity = [tex]\frac{distance}{time }[/tex]

on substituting the values in the above relation we get,

v = 45 = [tex]\frac{y}{x}[/tex]

on further rearranging of terms we get,

[tex]45x[/tex] = y

HENCE, required relation is 45x =y , which is a two variable equation.

Answer:

I need to empty 2 bottles to get Medicine A to 98% of the total bottles

Step-by-step explanation:

The first step is to find out what 99% of 200 is. This will give us how many bottles of "Medicine A"  are present.

99% of 200 is 198. This means that there are 198 bottles of Medicine A present.

The next step is to find out what 98% of 200 is. This will give us the number of bottles of "Medicine A " that will be left remaining.

98% of 200 is 196. There neede to be 196 bottles left after I have taken out and emptied a few bottles of Medicine A.

The last step is to subtract 196 from 198 bottles, to get the number of bottles that I need to empty.

This will be 198 - 196 = 2 bottles

I need to empty 2 bottles to get Medicine A to 98% of the total bottles

20 i think

Step-by-step explanation:

if it was 100 it would be 10. 100x2=200. thats how i got 20

Step-by-step explanation:

The sum of two opposite interior angles equals an exterior angle

50+?=115

?=115-50=65°

Answer:

60 degrees

Step-by-step explanation:

angles on a straight line add up to 180 degrees.

so do 180-115=60

because its an equilateral triangle, you can check whether it adds up to 180

60+60+50=180
