Step-by-step explanation:

72÷9= 8, so the boat was only doing 8mph going upstream (against the current) the return trip downstream only took 4 hours. 72÷18=4 meaning the boat was traveling at 18mph downstream (no current) there is a 10mph difference between upstream and downstream therefore the current had to be running at 10 mph. so the speed of the tug boat is 8mph without a current and the current is running at 10mph.

The polynomial [tex]x^3+ px^{2}-x-2[/tex] contains x - 1 as a factor.

The value of p = 2.

Given:

The polynomial [tex]x^3+ px^{2}-x-2[/tex] contains x - 1 as a factor.

Comparing x - 1 with x - a then

Substitute the value of x = 1, then we get

[tex]$1^3+p*1^2-1-2 = 0[/tex]

[tex]$1^{3}+p \cdot 1^{2}-1-2=0$$[/tex]

Apply rule [tex]$1^{a}=1$[/tex]

[tex]$&1^{3}=1,1^{2}=1 \\[/tex]

[tex]$&1+1 \cdot p-1-2=0[/tex]

Multiply: p-1 = p

1+p -1-2=0

Group like terms

p+1-1-2 = 0

Add/Subtract the numbers: 1-1-2 = -2

p-2 = 0

Add 2 to both sides

p-2+2 = 0+2

Simplify

p = 2

Therefore, the value of p = 2.

Step-by-step explanation:

the balloon was at 595 feet

595

then it dropped 495 feet

525-495= 30

the equals 30 means that it is currently 30 feet above the ground

and if it dropped another 15 feet it would not reach the ground, which is zero, the balloon would still be 15 feet above the ground

30-15= 15

so the balloon never reached zero

Answer: angle 1 = 56  and angle 2 = 124

Step-by-step explanation:

Supplementary angle equal 180 degrees

   let X be angle 1 and X +68 be angle 2

    x + x + 68 = 180

     2x + 68 = 180

          - 68     - 68

      2x = 112

        x = 56

        x + 68 = 56 + 68 = 124

Answer:

61 Nickels and 39 Dimes

Step-by-step explanation:

you have $3 and 5 cents in nickels and 3$ and 90 cents in Dimes

it all equals 100 coins all together

The number of dimes is 39 dimes

The number of nickels 61 nickels

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the number of dimes be = x

Let the number of nickels be = y

So , total number of coins = 100

x + y = 100   be equation (1)

And , the total amount = $ 6.95

The cost of one dime = $ 0.10

The cost of one nickel = $ 0.05

So , total cost = 0.10x + 0.05y = 6.95   be equation (2)

Now , on simplifying equation (1) and equation (2) , we get

x + y = 100

10x + 5y = 695   be equation (3)

Divide equation (3) by 5 , we get

2x + y = 139   be equation (4)

Now , Subtracting equation (1) from equation (4) , we get

x = 39

Therefore , the number of dimes is 39 dimes

Substituting the value of x in equation (1) , we get

x + y = 100

y + 39 = 100

Subtract 39 on both sides of the equation , we get

y = 61

Therefore , the number of nickels is 61 nickels

Hence ,

The number of dimes is 39 dimes

The number of nickels 61 nickels
