a boat is going 144 miles upstream on a river. the speed of the boat in still water is 60 miles per hour. the speed of the river current is 80% less than the speed of the boat in still water. how long does the journey take?
Answers
Answer:
45
Step-by-step explanation:
Answer:
3 hours
Step-by-step explanation:
the speed of the river current is 80% less
80% of 60 is 48
so the speed is now 48 mph, because the river is pushing the boat back (duh)
144 miles/ 48 mph is 3 hours.

Which system of equations can be represented by this matrix?
Answers
You put the numbers in order of the letters and if a letter is missing you put 0
Answer: C
Step-by-step explanation: As you most likely know, the matrix represents the system of equations. If you assume that x is the far left column, that y is the column adjacent to it, and that y is to the left of the line, you can assume that these are the equations represented:
1x-3y+2z=-9
1x+0y+1z=1
0x+2y-1z=7
which can be simplified to
x-3y+2x=-9
x+z=1
2y-z=7

Oat porridge is sold in two sizes of box.
Size of box Weight of porridge
small
large
6259
350g
Walter buys 5 large boxes of oat porridge and some small ones too.
In total, he buys 4175g of porridge.
Work out the number of small boxes of oat porridge Walter buys.
Note: Make your final answer clear by writing ... small boxes.
Total marks: 3
Answers
Answer:
3 boxes of small porridge
Step-by-step explanation:
625g x 5 = 3125
4125-3125=1000
1000 divided by 350 = 2.8
so there will be 2 full boxes of small porridge and 1 not full box of porridge.
Walter buys 3 small boxes of oat porridge.
What is an expression?When used to represent a quantity or a mathematical relationship, symbols and/or numbers are combined to form an expression in mathematics. It may contain exponents, brackets, variables, constants, and mathematical operations like addition, subtraction, multiplication, and division.
To begin, let's determine how much porridge is contained in the five enormous boxes:
5 x 625 = 3125g
Determine how much porridge is contained in the little boxes since we know that Walter purchases 4175g in total.
4175 - 3125 = 1050g
Assuming that there are 350g of porridge in each small box, we can calculate the number of small boxes by dividing the total weight of the porridge by the weight of each small box:
1050 / 350 = 3
Therefore, Walter buys 3 small boxes of oat porridge.

Solve the following problem:
Which triangles are similar? Which sides are proportional?
Answers
9514 1404 393
Answer:
ΔA₁CA ~ ΔBCB₁
Step-by-step explanation:
The triangles share angle C. The 30° angles are also congruent, so the triangles are similar by the AA theorem.
It is convenient to name the similar triangles by matching the similar angles. Here, angle A₁ matches the acute angle at B, and (of course) angle C matches itself. So, we can name the triangles using those two angles in that order.

You take out a loan from the bank for $4350. The bank charges an annual simple
interest rate of 15% and you are going to pay the loan back in 4 years. What is the
total amount of INTEREST you will pay back to the bank?
Answers
Answer:
He will have $4491.38 after 5 year
Step-by-step explanation
Simple Interest = (Principal × rate × time)/100
SI = (4350 × 0.65 × 5)/100
SI = 141.375
Interest after 5 years = $141.38
The total money he will have after 5 years is
$4350 + $141.38
= $4491.38
Answer:
I think the total amount would be $2610
Step-by-step explanation:
because you would multiply $4350 times 15% to get 652.5 a year so just multiply that by 4 and you have your answer which is $2610 the total amount of interest.
Leanne is picking out some movies to rent, and she is primarily interested in children's movies and comedies. She has narrowed down her selections to 18 children's movies and 7 comedies. Step 2 of 2 : How many different combinations of 3 movies can she rent if she wants at least one comedy
Answers
Answer:
If she wants at least one comedy, there are 1484 different combinations.
Step-by-step explanation:
The order in which she wants to pick the movies is not important. So, we use the combinations formula to solve this question.
Combinations formula:
[tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
In this question:
She wants combinations of 3 movies, with at least one comedy. The easiest way to find this is finding the total number of combinations of 3 movies, from the set of 25(18 children's and 7 comedies), and subtract by the total number without comedies(which is 3 from a set of 25). So
Total:
3 from a set of 25.
[tex]C_{25,3} = \frac{25!}{3!(25-3)!} = 2300[/tex]
Without comedies:
3 from a set of 18.
[tex]C_{18,3} = \frac{18!}{3!(18-3)!} = 816[/tex]
At least one comedy:
[tex]2300 - 816 = 1484[/tex]
If she wants at least one comedy, there are 1484 different combinations.
6. A Civil War cannon is placed at the base of a hill. The cannon is fired at an angle toward the hill. The path of the cannon ball is parabolic and can be represented by y=-0.04x2 + 4x + 1, where y represents the height of the ball in meters and x represents the horizontal distance of the ball from the cannon. The incline of the hill can be represented by the equation y = 0.8125x. How far will the cannon ball have moved horizontally from the cannon when it hits the hill?
Answers
Answer: 80
Step-by-step explanation:
Following are the solution to the given question:
Its canon is placed on the floor, as we knew from the very first part. So, for Canon, [tex]y = 0[/tex]. Consider the origin, which is located at the bottom of a hill. So, to find the canon's x value, we must solve the quadratic formula: [tex]-0.04x^2 + 4x + 1 = 0[/tex] , which has only one negative solution,[tex]0.25.[/tex] We know that the x value cannot be positive as this would suggest that the cannon is located inside of the hill. This hill's equation is[tex]y = 0.8125x[/tex] , and we understand that now the cannonball will collide with it at the junction of the hill line and its hyperbolic path. So, when the formulas are combined, we get[tex]\to 0.8125x =-0.04x2 + 4x + 1\\\\\to 0.04x^2 - 3.1875 - 1 = 0\\\\[/tex]
It has the only positive root as [tex]80[/tex]. As a result, the y value is [tex]0.8125\times 80 = 65[/tex]The horizontal distance will be the x value + the [tex]0.25 = 80.25[/tex]Its horizontal distance = x value+[tex]0.25= 80+0.25 = 80.25[/tex]Learn more:
