Find the area of the trapezoid a21 b22.50 c11.25 d42

Answer:

314,880

Step-by-step explanation:

If the population decreases by 1.6% per year, this means the population is 98.4% of the population of the previous year. What this means is we can multiply the current population, 320,000, by 98.4/100, as 98.4/100 is equivalent to 98.4%. This gets us 314,880.

Answer:

314880

Step-by-step explanation:

Respuesta. La probabilidad de sacar um 3 seria de 16.66% osea un sexto ,de sacar un numero par es de tres sexto osea del 50% y de sacar un numero impar es de tres sexto osea 50% igual ke los pares y de sacar un numero menor k 7 es de 6 sobre 6 osea 100%.

El valor uno corresponde al suceso seguro: lanzamos un dado al aire y la probabilidad de que salga cualquier número del 1 al 6 es igual a uno (100%). El resto de sucesos tendrá probabilidades entre cero y uno: que será tanto mayor cuanto más probable sea que dicho suceso tenga lugar.

Answer: 1/8 pounds of roasted almonds

Step-by-step explanation:

There are six friends and each of them are to receive and equal piece out of a 3/4 pound of roasted almonds.

The almonds each friend will get will therefore be the 3/4 pack divided by 6:

= 3/4 ÷ 6

= 3/4 * 1/6

= 3/24

= 1/8 pounds of roasted almonds

When dividing by a number, you can instead multiply by the inverse of that number.

Answer:

You would receive $510.08 in return.

Step-by-step explanation:

In order to find the answer, you can use the formula to calculate the future value:

FV=PV*(1+i)^n

FV=future value

PV= present value= 500

i= interest rate=0.03/12=0.0025 per month

n= number of periods of time= 8

Now, you can replace the values in the formula:

FV=500*(1+0.0025)^8

FV=500*(1.0025)^8

FV=510.08

According to this, the answer is that you would receive $510.08 in return.

Answer:

1/2

Step-by-step explanation:

12 out of 24 is 1/2

5/7 = 35 kg

1/7 = 7 kg

Peter weighs 49 kg

49 - 8 = 41 kg

Ailen weighs 41 kg

49 + 41 = 90kg

Their total weight is 90 kg

Answer:

Step-by-step explanation:

parallel lines never cross

Answer:

The second answer is correct

Answer:

In this equation, we can start by understanding that "x" has a value of 8, as given in the ordered pair. When multiplied by 5, this leads to "40 - 2y = 30". Next, we can subtract 40 from both sides of the equation. This leads us to a value of "-2y = -10". The next step would be to divide both sides by -2 as a way of isolating "y", which leads us to a final value of "y = 5". The final ordered pair would be (8,5).

Answer:

the y intercept is -2

Step-by-step explanation:

the y intercept is always the value on the end

Answer slope-intercept form is y = mx+ b y = m x + b, where m m is the slope and b b is the y-intercept. y = mx +b y = m x + b Find the values of m m and b b using the form y = mx+b y = m x + b.

Answer:

x = 20°

Step-by-step explanation:

3x - 10° + 5x + 30° = 180° { being co-interior angles }

8x + 20 ° = 180°

8x = 180° - 20°

8x = 160°

x = 160° / 8

x = 20°

Answer:

c on edge

Step-by-step explanation:

just took the quiz

The equation representing the circle A is (x – 4)² + (y + 5)² = 36.

A circle is a spherical shape without boundaries or edges. A circle is a closed, curved object with two dimensions in geometry.

The general equation of circle is given by equation

( x - h )² + ( y - k )² = r²

Where,  ( h, k ) is the centre and 'r' is the radius.

As, the circle has a shift of 4 units on the +x axis.

The circle has a shift of the 5 units on the -y axis.

As, the circle has a radius of 6 units from the graph.

So, (h,k) = (4, -5).

Substitute the values of (h,k) in the general equation of the circle.

( x - 4 )² + ( y - (-5) )² = 6²

( x - 4 )² + ( y + 5 )² = 36

Therefore, the equation of circle becomes ( x - 4 )² + ( y + 5 )² = 36.

Answer:

step 1. y - y1 = m(x - x1). This is the standard line equation given a point and a slope.

step 2. parallel lines have the same slope so the slope is -4.

step 3. y - (-5) = -4(x - (-4)).

step 4. y + 5 = -4x - 16.

step 5. y = -4x - 21.

Step-by-step explanation:

turn the percentage into a decimal (0.89) and multiply it by the number of questions

Answer: 178

Step-by-step explanation: hope this help

Answer:

no solution

Step-by-step explanation:

Given

- 2(v - 2) = - 3 - 2v ← distribute left side

- 2v + 4 = - 3 - 2v ( subtract 4 from both sides )

- 2v = - 7 - 2v ( add 2v to both sides )

0 = - 7 ← not possible

This indicates the equation has no solution

90(5/6)

75

9514 1404 393

Answer:

  75

Step-by-step explanation:

90 = 6 × 15

There are 15 6-day periods in 90 days. The gardener will have mowed ...

  15 × 5 = 75

times in those 15 periods.

He will mow 75 times in a 90-day period.

__

If you like, you can set up a proportion for the unknown number of mowings (m).

  mows/days = m/90 = 5/6

Multiply by 90 to solve for m.

  m = 90(5/6) = (90/6)(5) = 15(5) = 75 . . . . . . this should look like the above

Given:

The  function that represents how the amount of fuel changes as a function of distance flown is

[tex]f(x)=-0.9x+665[/tex]

where x represents miles flown, and f(x) represents the amount of fuel remaining.

To find:

The rate of change for this scenario.

Solution:

The slope intercept form of a linear function is

[tex]y=mx+b[/tex]        ...(i)

Where, m is the slope or rate of change and b is the y-intercept.

We have,

[tex]f(x)=-0.9x+665[/tex]        ...(ii)

On comparing (i) and (ii), we get

[tex]m=-0.9[/tex]

Therefore, the rate of change for this scenario is -0.9. It means, the amount of fuel in the airplane is decreasing by 0.9 gallons per mile.
