A motorboat travels 189 kilometers in hours going upstream and 693 kilometers in 7 hours going downstream. What is the rate of the boat in still water and what is the rate of the current?
Rate of the boat in still water: km/h
Rate of the current: km/h
Answer:
rate of the boat in still water: 81 km/h
rate of the current: 18 km/h
Step-by-step explanation:
Rate of the boat in still water:81 km/h
Rate of the current: 18km/h
What is speed?Speed tells us how fast something or someone is travelling. You can find the average speed of an object if you know the distance travelled and the time it took. The formula for speed is speed = distance ÷ time.
Given
b= speed of boat in still water c=speed of current
"boat travels 693 kilometers in 7 hours going downstream" Going downstream, the boat travels b+c km per hour. b+c km/hr = 693 km/7hr = 99 km/hr
b+c=99
"boat travels 189 kilometers in 3 hours going upstream" Going upstream, the boat travels b-c km per hour. b-c km/hr = 189 km/3hr = 63 km/hrb-c=63
Add the equations together to eliminate the c terms: b+c=99 b-c=63 2b = 162, therefore, b= 81
b+c= 99, so c = 99 - b= 18

4. The two legs of a right triangle are equal and the square of its hypotenuse is 50. Find the
length of each leg.
Answer:
[tex]Opposite = Adjacent= 5[/tex]
Step-by-step explanation:
Given
[tex]Hypotenuse^2 = 50[/tex]
[tex]Opposite = Adjacent[/tex]
Required
Find the length of each leg
This is calculated using Pythagoras Theorem
[tex]Opposite^2 + Adjacent^2 = Hypotenuse^2[/tex]
[tex]Opposite^2 + Adjacent^2 = 50[/tex]
Represent the opposite and adjacent with x
[tex]x^2 + x^2= 50[/tex]
[tex]2x^2 = 50[/tex]
Divide both sides by 2
[tex]x^2 = 25[/tex]
Take square roots
[tex]x = 5[/tex]
Hence:
[tex]Opposite = Adjacent= 5[/tex]

EQ: How do I solve an inequality with
variables on both sides?
Step-by-step explanation:
The steps to solve inequalities with variables on both sides are:
1. By using basic operations like addition and subtraction, bring all "x" terms to the left side.
2. Bring constants to the right side. If we have any fractions in the given inequality, we have to take L.C.M and simplify.
L.C.M= least common multiple

Identifying Proportional Relationships
Which graph represents a proportional relationship?
Answer:
There aren't any graphs that you attached so i can't see which one is a proportional graph, but the one that is going up by a constant proportional rate of change would be the proportional graph.
Proportional relationship graphs always start at the point 0 for x and y. The line always crosses through to origin. 0
Step-by-step explanation:
Proportional relationships are relationships between two variables where their ratios are equivalent. Another way to think about them is that, in a proportional relationship, one variable is always a constant value times the other. That constant is know as the "constant of proportionality".
Answer:
THERE are no graphs

[tex]x=\frac{-4}{33}[/tex]
Step-by-step explanation:
Let's start with simplifying the equation. To do this, let's simplify the parenthesis. We can use the distributive property to simplify the parenthesis. We now have
[tex]2x-6x+9+3=45[/tex]
Next, we can start adding. We can add 2x and 6x, and 9 and 3.
[tex]-4x+12=45[/tex]
Now that we've simplified the equation, we can start solving the equation. First, let's subtract 12 from each side.
[tex]-4x=33[/tex]
The last thing that we need to do is divide -4 from each side.
[tex]x=\frac{-4}{33}[/tex]

Step-by-step explanation:
Two important ingredients for baking bread are yeast and flour. To make a loaf of
bread of at most 40 servings, maintain a yeast to flour ratio of 1:200. If you're making
a loaf of more than 40 servings, use a ratio of 1:180.
If you're making 40 servings of bread and using 0.35 oz of yeast, how many ounces of
flour do you need?
If you're making 90 servings of bread and using 360 oz of flour, how many ounces of
yeast do you need?
Using proportions, it is found that:
70 ounces of flour are needed for 40 servings of bread and using 0.35 oz of yeast.180 ounces of yeast are needed for the 90 servings of bread using 360 oz of flour.What is a proportion?A proportion is a fraction of total amount, and the measures are related using a rule of three.
For 40 servings:
1 oz of yeast is equivalent to 200 oz of flour. How many oz of flour are needed for 0.35 oz of yeast?The rule of three is:
1 oz yeast - 200 oz flour
0.35 oz yeast - x oz flour.
Applying cross multiplication:
[tex]x = 200(0.35) = 70[/tex]
70 ounces of flour are needed for 40 servings of bread and using 0.35 oz of yeast.
For 90 servings:
1 oz of yeast is equivalent to 180 oz of flour. How many oz of yeast are needed for 360 oz of flour?The rule of three is:
1 oz yeast - 180 oz flour
x oz yeast - 360 oz flour.
Applying cross multiplication:
[tex]2x = 360[/tex]
[tex]x = \frac{360}{2}[/tex]
[tex]x = 180[/tex]
180 ounces of yeast are needed for the 90 servings of bread using 360 oz of flour.

This triangle has one side that lies on an extended line segment.
Based on this triangle, what statement about x is true?
x = 27 because 180−109−44=27
x = 65 because 109−44=65 and 44 + 65 = 109
x = 71 because 180−109=71
x = 153 because 109 + 44 = 153 and 153−44=109
Answer:
65°

Of the eggs produced by salmon,80% hatch, and of those, 25% survive to migrate to the ocean. How many eggs are needed to produce 100 salmon that migrate to the ocean?
Answer:
500 eggs are needed

so 1/4 or the 80 percent make it to the ocean so 20 percent of total salmon make it to the ocean.
so total number of eggs x
1/5x=100
x=500
if my answer helps please mark as brainliest.
Answer:
Step-by-step explanation:
25% of (80% of eggs) = 0.25 × 0.80 × eggs = 100
Eggs = 100/(0.25 × 0.80) = 500
500 eggs are needed to produce 100 salmon.
