Answer:

1. 15.708

2. The radius would be half of the distance across the drain, or half of the diameter. Half of 3.8cm, or 3.8cm / 2 is 1.9cm.

The circumference is the distance around the drain, or if you trace the entire circle. The formula to find the circumference of a circle is 2 multiplied by pi and the radius of the circle, or C = 2(pi)r. Here, we just found the radius, so the circumference is 2 * pi (which is approximately 3.14) * 1.9cm, or approximately 11.9cm!

Step-by-step explanation:

The total amount of money saved will be 50 - 16c

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.

Given are 4 friends who are buying tickets for a concert. The cost to buy one ticket is c dollars. If you buy all the tickets together, there is a discount and the cost is (5c - 12.5) dollars.

When buyed separately, the total cost = $4c

When bought together, the total cost = $4(5c - 12.5)

Money saved = 4c - 4(5c - 12.5) = 4c - 20c + 50 = 50 - 16c

Therefore, the total amount of money saved will be 50 - 16c

Answer:

The answer would be 81 brown ducks.

Step-by-step explanation:

All we have to figure out 75% of 108.

0.75 multiplied by 108 is 81

So the answer would be 81 brown ducks.

Answer:

The length of Bob's snake = x = 80 inches

The length of Mary's snake = y = 30 inches

Step-by-step explanation:

Let the length of Bob's snake = x

the length of Mary's snake = y

From the above question:

Bob's pet snake is 10 inches shorter than three times the length of Mary's pet snake.

x = 3 × y - 10

x = 3y - 10

If both their snakes laid together end to end measure 110 inches, how long is Bob's snake?

x + y = 110 inches

Substance 3y - 10 for x

3y - 10 + y = 110

Add 10 to both sides of the Equation

3y + y -10 + 10 = 110 + 10

4y = 120

y = 120/4

y = 30 inches

x + y = 110 inches

x + 30 inches = 110 inches

x = 110 inches - 30 inches

x = 80 inches

Answer to the problem: 189 beech trees

Answer:

$19.50 I think?

Step-by-step explanation:

use long division if a calculator is not allowed.

Answer: 18.5% of the bill.

Step-by-step explanation:

Since the bill was 42 dollars while the total amount was 49.77, we need to subtract 42 by 49.77.

49.77 - 42 = 7.77.

So the tip was $7.77.

But then we also have to find the tip as a percentage.

So we should do 7.77 divided by 42, because 42 is the original amount.

7.77 ÷ 42 = 0.185, but as a percent you have to move to the left two places. So the decimal is 18.5.

In conclusion, the tip was 18.5% of the bill.

Hope this helps!

Responder:

Los valores de y son 3/5 y -1

Los valores de x son = -12/5 y -4

Explicación paso a paso:

Dadas las eqautions;

x + 3 = y ...... 1

x ^ 2- 16y ^ 2 = 0 ..... 2

Sustituya la ecuación 1 en 2 que tendremos;

x ^ 2- 16y ^ 2 = 0

x² - 16 (x + 3) ² = 0

x²-16 (x² + 6x + 9) = 0

x²-16x²-96x-144 = 0

-15x²-96x-144 = 0

15x² + 96x + 144 = 0

5x² + 32x + 48 = 0

Al factorizar tendremos;

5x + 12 = 0 yx + 4 = 0

x = -12/5 y -4

Obtenga los valores de y;

recuerda que y = x + 3

Si x = -12/5

y = -12/5 + 3

y = 3/5

Si x = -4

y = -4 + 3

y = -1

Por tanto, los valores de y son 3/5 y -1

Answer:

Khalid’s rate is ___140_ miles per hour. Jesse’s rate is _150___ miles per hour. So, _Jesse’s___ train traveled at a faster speed.

Step-by-step explanation:

The general equation of a straight line is

y = mx + b

for y = 150x

We have the slope as 150

This is 150 miles/hour

This relates to Jesse’s train speed

for Khalid, we have his own speed obtainable from the graph

The speed is simply the slope of the graph

We proceed to select two points from the graph and find the slope

The points are; ((1,140) and (4,560)

Mathematically, the slope will be;

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

m = (560-140)/(4-1) = 420/3 = 140 miles per hour

Given :

A parallelogram has sides 8 ft and 14 ft the height corresponding to the 14 ft base is 4 ft.

To Find :

The height corresponding to the 8 ft base.

Solution :

Since, both parallelogram are similar. So, ratio of the sides of parallelogram is similar in both the cases.

[tex]\dfrac{h_1}{h_2}=\dfrac{b_1}{b_2}\\\\\dfrac{8}{14}=\dfrac{h_1}{4}\\\\h_1 = \dfrac{8\times 4}{14}\\\\h_1 = 2.285 \ ft[/tex]

Therefore, the height corresponding to the 8 ft base parallelogram is 2.285 ft.

The equation is y = -x - 4.

Answer:

9x² + 16y² - 24xy

Step-by-step explanation:

(3x - 4y)²

⇒ (3x)² + (4y)² - 2 (3x) (4y)                                            {(a - b)² = a² + b² - 2ab}

⇒ 3²x² + 4²y² - 2 (12xy)

⇒ 9x² + 16y² - 24xy

Answer:

A=2.5

B=2

Step-by-step explanation:

A parallelogram has to have the opposite sides equal each other. In this case side LM and side ON have to be equal.

We can compare the two sides using algebra.

4b+7=8b-1

Using simple methods, we can isolate b on a single side.

1+7=8b-4b

8=4b

b=2

From this we learn b is 2. To find out the value of A on side MN and LO, we will plug in the value for b at all instances of B in this equation.

2a = 2b+1

2a = 2(2)+1

2a=4+1

2a=5

a=2.5
