Answer:

Jim.

Step-by-step explanation:

Descending results in a greater depth so we add the measurements when they descend and rising results in a lower depth so we minus the measurements when they rise. The surface area has no depth yet, so it is 0 feet depth.

Jim = 8 + 20 - 7 + 12

     = 33

Carla = 0 + 15 -7 + 20

         = 28

Since 33 feet is deeper than 28 feet, Jim rested at a greater depth.

Answer:

65%

Step-by-step explanation:

What you need to do is add both the clean and the dirty mugs together to get a total amount of mugs (60) and then divide 39 by 60 because you are dividing the mugs that you want to find the percentage of by the total amount of mugs. The equation would look like this:

39/60=0.65

therefore, the answer is 65%

Answer:

A 33 degree change

Step-by-step explanation:

67-34=33

Answer: 4x³-19x+15

Step-by-step explanation:

We are given f(x) and g(x). Since we need to find f(x)·g(x), we multiply f(x) and g(x).

[tex](2x+5)(2x^2-5x+3)[/tex]                               [distribute by FOIL]

[tex]4x^3-10x^2+6x+10x^2-25x+15[/tex]           [combine like terms]

[tex]4x^3-19x+15[/tex]

Now we know [tex]4x^3-19x+15[/tex] is the correct answer.

Answer:

0.56%

Step-by-step explanation:

Percentage error

[tex] = \frac{2500 - 2486}{2500} \times 100 \\ \\ = \frac{1400}{2500} \\ \\ = 0.56\%[/tex]

The crowd at a sporting event is estimated to be 2,500 people, the exact attendance is 2,486 people, the percentage error is, 0.56%

The percentage is a mathematical term, which means a number or a ratio which is represented in fractions of 100. We use the '%' symbol to represent the percentage.

Formula for percentage;

Percentage = (present quantity/whole quantity)×100

Given that,

The crowd estimated to be 2,500 people

The exact attendance is 2,486 people

Percentage error = ?

Percentage error = (estimated value- exact value)/estimated value×100

Percentage error =   (2,500 - 2,486) /2500×100

                             =  0.56%

So, the percentage error is 0.56%

Answer:

[tex]r \cdot 4 = z[/tex]

Step-by-step explanation:

An expression means that we don't know enough to create an equation. So, this means we will mostly be using variables.

John runs r amount every day. We need to create an expression for if he runs r amount for 4 days.

[tex]r \cdot 4 = z[/tex]

r = how much he runs per day

4 = how many days he runs

z = how much he runs this week

This is your expression!

Answer:

r * 4 = a

Step-by-step explanation:

If John runs the same amount everyday (r) for the past four days, we can multiply 4 by r

r * 4

We don't have enough information to write the answer to the expression so in its place we can put a variable. (In this case, I chose a)

r * 4 = a

So a possible expression for this problem is r *4 = a

Hope this helps! Have a great day! :)

Answer:-2

Step-by-step explanation:

-y+2x=-1 needs to be changed to y=-2x-1 so that you can set the two equation equal to each other in order to solve for x. That makes it -2x-1=1/2x+4

-4= -4

-2x-5 = 1/2x

+2x = +2x

-5 = 2.5x

div. 2.5 div. 2.5

X= -2

Check: y= -2(-2)-1 Y=3

y=1/2(-2)+4 Y=3

834 and 799

Step-by-step explanation:

x+y=1633

x-y=35

2x= 1668

x=834

y=799

Answer:

((819.458,813.542)

Step-by-step explanation:

sum of two numbers=1633

x+y=1633----equation (i)

their difference=35

(x-y)^2=35----equation (ii)

solve simultaneous equation by using substitution method

x+y=1633

make x the subject of the formula

x=1633-y---(i)

substitute equation (i)into (ii)

(x-y)^2=3

(1633-y-y)^2=35

(1633-2y)^2=35

apply square root both sides

√(1633-2y)^2=√35

1633-2y=√35

-2y=√35-1633

-2y=-1627.08392

divide both sides by -2

y=813.5419601

substitute the value of y in equation (i

x=1633-y

x=1633-813.5419601

x=819.4580399

therefore the two numbers are (819.458, 813.542)

Answer:

-3

Step-by-step explanation:

the answer is negative 3, because when x is two, y is three

Answer:

f(2) = -3

Step-by-step explanation:

This is the answer because:

1) The question is basically asking what the y-cordinate is.

2) In order to find the y-cordinate, look at the graph and find where 2 is on the x-axis. Then, see wheree the y-coordinate is on the same line a the x-cordinate which is 2.  

3) When you line up the cordinates, you can see that where x is 2, y is -3.

Therefore, the answer is -3.

Answer:

4x+6

Step-by-step explanation:

The perimeter of the field can be obtained by calculating the distance around the field.

in this case, we know that the shape of the field is a rectangle.

The perimeter of a rectangle can be obtained by using the formula

[tex]2(l+b)[/tex]

The width of the rectangle is given as x yards

The length of the rectangle is given as x +3 yards

Therefore, an expression to determine the perimeter of the rectangle can be given as

Answer:

y=-3x+8

Step-by-step explanation:

y=mx+b

(m=slope and b=y-intercept)

Answer:

Step-by-step explanation:

let’s use this equation y = mx + b

where m = slope

and b = y intercept

since slope is -3, m = -3

and since y intercept is 8, b = 8

so the equation is

y = -3x +8

Answer:

9.072

Step-by-step explanation:

Answer:

9.072

Step-by-step explanation:

For this problem, we will simply use the property of 0 and addition to accumulate a sum.

Note, any digit not shown to the right of a decimal can be written with a zero. So 5.9 can be rewritten as 5.900.

Let's perform the addition.

5.900

+ 3.172

-----------

9.072

Using the idea of zeros to the right of the decimal, we are able to trivially complete this sum.

Hence, the answer is 9.072.

Cheers.
