Whats the question?

Step-by-step explanation:

The answers to all the parts are -

Equation : (1/2)n + n = 90

Apples picked up by Nate : 60

Apples picked up Laura : = 30

A mathematical expression is made up of terms (constants and variables) separated by mathematical operators. A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.

We have Nate and Laura picked apples. Laura picked 1/2 as many as Nate picked. Together they picked 90 apples.

Let [n] stand for the number Nate picked. Then, the number of apples picked up by Laura will be (1/2)n. Then, we can write -

Equation : (1/2)n + n = 90

1.5n = 90

n = (90/1.5)

n = 60

Apples picked up by Nate : 60

Apples picked up Laura : 60/2 = 30

Therefore, the answers to all the parts are -

Equation : (1/2)n + n = 90

Apples picked up by Nate : 60

Apples picked up Laura : = 30

Answer: Based on the given data, the coconut has a height of 210 units and it hits the ground between 4 to 5 seconds where the height is less than zero or a negative number, this means that probably the coconut was buried in the ground at these times. The correct answers are:

The values of h(t) when t = 4 and 5 should be 0. This could also be without the assumption that the coconut is buried after falling.

Answer:

36 - 1/2x = 0

72 minutes

Step-by-step explanation:

there is a total of 3 feet in the pool at the start, 1 ft = 12 in, and 3 ft = 36 in. the pool is losing water, so we have to subtract. it is losing water at a rate of -1/2 in per minute, and we don't know how many minutes it will take

we have to set it equal to 0 because we are trying to find out how long it will be until the pool is completely drained, which is when there will be no water left, so it will be 0

subtract 36 from both sides

-1/2x = -36

divide both sides by -1/2

x = 72

72 minutes

Substitute y = 2x - 4 to x + 2y = 12:

x + 2(2x - 4) = 12    use distributive property

x + (2)(2x) + (2)(-4) = 12

x + 4x - 8 = 12     add 8 to both sides

5x = 20    divide both sides by 5

x = 4

Put the value of x to the first equation:

y = 2(4) - 4

y = 8 - 4

y = 4

Answer:

x=4, y=4

Step-by-step explanation:

y=2x-4;

x+2y=12

We can use substitution since the first equation is solved for y

Where ever you see y in the second equation, replace it with 2x-4

x + 2(2x-4) = 12

Distribute the 2

x+4x-8 = 12

Combine like terms

5x-8=12

Add 8 to each side

5x-8+8=12+8

5x=20

Divide by 5

5x/5 = 20/5

x =4

We still need to solve for y

y = 2x-4

We know x =4

y = 2(4) -4

y = 8-4

y=4

Answer:

260 in economy

100 in business

Step-by-step explanation:

ok so out of 18 seats 13 are economy and 5 are business and since 18 times 20 is 360 we multiply each of these by 20 so 13 times 20 is 260 20 times 5 is 100 there you go

Answer:

Pi is a never ending number.

The answer is B) because it is not a never ending number

Also, the question in the picture asks which is a rational number, not irrational

Answer:

y = 0 and z = 5

Step-by-step explanation:

the denominator of the expression cannot equal zero as this would make the expression undefined Equating the denominator to zero and solving gives the values that y and z cannot be

solve y(z - 5) = 0

equate each factor to zero and solve

y = 0 ← excluded value

z - 5 = 0 ⇒ z = 5 ← excluded value

Answer:

  q = 10

Step-by-step explanation:

The desired form is a rearrangement of the given equation, divided by the leading coefficient.

A monic polynomial is one with a leading coefficient of 1. The desired form requires that we start from that condition. In order to avoid fractions, we can begin by subtracting the constant term on the left.

  2x^2 -20x +49 = 19 . . . . . . given

  2x^2 -20x = -30 . . . . . . . . subtract 49

  x^2 -10x = -15 . . . . . . . . . divide by 2

The square of the binomial a+b is given by ...

  (x +b)^2 = x^2 +2bx +b^2

That is the constant term on the right is the square of half the coefficient of x. To achieve this perfect square trinomial in our equation, we need to add the square of half of -10.

  x^2 -10x +25 = -15 +25 . . . . . . add (-10/2)^2 = 25 to both sides

  (x -5)^2 = 10 . . . . . . . . . . . write in the desired form

The value of q in the form ...

  (x -p)^2 = q

is 10.

Answer:b = (2A - hB)/h

Step-by-step explanation:

See , we know area of a trapezoid is equal to 1/2*(sum of parallel sides)* perpendicular distance between parallel sides.

Here B and b are parallel sides which we know by comparing the equation.

And 'h' here is the perpendicular distance between parallel sides.

We have to write the equation in terms of one of the parallel sides 'b'

Our formula is A = 1/2*h*(B+b)

I.e. 2A = h*(B+b) (Multiplying both sides by 2)

I.e. 2A - hB = hb

I.e. b = (2A - hB)/h

Answer:

Density = 1.042  grams /cm^3

Step-by-step explanation:

Work out the mass of each of three in a unit volume (cm^3)

Givens

Mixture

35 cm^3 Apple Juice = 1.04 grams / cm^3 * 35 cm^3 = 36.4 grams

25 cm^3 Fruit = 1.6 grams/cm^3 * 25 cm^3 =                  40    grams

270 cm^3 water = 0.99 * 270                                        267.3 grams

Total Mixture

Density

Density = mass / volume = 343.7 / 330 = 1.0415

Answer

1.042 grams / cm^3  

The density of the resulting drink is; 1.042 grams per cm³.

To find the density of the resulting drink, we need to first determine the mass of each of the constituents.

The masses of the constituents can be found as follows;

For apple juice;

For fruit syrup;

For sparkling water;

Therefore, the total mass of the drink is;

And, since the total volume of the drink is 330cm³

Density of the drink = 1.042 grams per cm³.

Answer:

5 mililmiters = 0,005 meters = 0,000005 kilometers

2 kilometers = 2000 meters

Step-by-step explanation:

km  / hectometer / decameter / meter / dcm / centimeter / milimeter

1000 m /     100  m   /    10   m     <     1  >    0,1 m/    0,01  m     /  0,0001 m

1 meter = 0,  1 decimeters / 0, 01 centimeters /0, 000 1 millimeters

1 meter = 10 decameters / 100 hectometers / 1000 kilometers

so 5 millimeters = 0,005 meters = 0, 000 005 kilometers

so  2 km = 2 000 meters  = 2 000 000 millimeters

the reference unit of measure is the meter.

The factored equivalent expression for 12z+36 is 12(z + 3) after factoring out the common factor of 12.

When asked to write all factored equivalent expressions for 12z+36, we look for common factors. Both terms have a common factor of 12. Factoring out the 12, we get 12(z + 3). There are no other common factors, and the expression cannot be factored further as both terms within the parentheses are prime with respect to each other.

Answer:

y = 6/5 x-1  slope intercept form

6x-5y = 5  standard form

Step-by-step explanation:

We have the points  (0,-1) and (-5,-7)

We can find the slope using

m = (y2-y1)/(x2-x1)

 = (-7--1)/(-5-0)

 = (-7+1)/(-5-0)

 = -6/-5

 = 6/5

We also have the y intercept ( when x=0)  It is -1

We can use the slope intercept form of the equation y = mx+b

y = 6/5 x-1

Depending on what you mean when you say simplify your answer

We can put it in standard form  ax+by = C

Multiply both sides by 5

5y =5* 6/5 x-1*5

5y = 6x-5

Subtract 6x from each side

-6x+5y = 6x-6x-5

-6x+5y = -5

Multiply by -1

6x-5y = 5
