What is the value of 3a - 8b / 3b
when a = -2 and b = -4?

Answer:

[tex]\angle 2 =145^\circ[/tex]

Step-by-step explanation:

Given

[tex]\angle 4 = 55^\circ[/tex]

Required

Find [tex]\angle 2[/tex]

From the attached image, we have:

[tex]\angle 5 = 90[/tex] --- right angle

So, we have:

[tex]\angle 5 +\angle 4 = 90 + \angle 4[/tex]

Substitute: [tex]\angle 4 = 55^\circ[/tex]

[tex]\angle 5 +\angle 4 = 90 + 55[/tex]

[tex]\angle 5 +\angle 4 = 145[/tex]

To solve for [tex]\angle 2[/tex], we have:

[tex]\angle 2 =\angle 5 +\angle 4[/tex] --- Vertically opposite angles

So:

[tex]\angle 2 =145^\circ[/tex]

Answer:

x = 5

Step-by-step explanation:

Since this shape is a quadrilateral, the sum of the interior angles is 360.

Equation:

81 + 20x - 16 + 15x + 30 + 16x + 10 = 360

51x + 105 = 360

51x = 360 - 105

51x = 255

x = 5

Answer:

B. The graph of his the graph of g vertically shifted up 1 unit.

Step-by-step explanation:

[tex]Given:-[/tex]

[tex]g(x)=x^2[/tex]

[tex]h(x)=g(x)+1[/tex]

[tex]so,h(x)=x^2+1[/tex]

Answer:

I got 21 ft

Step-by-step explanation:

I converted all of the measurements that were shown in feet to inches (there are 12 inches in 1 foot), then added all of the sides together. Once I got that answer, I converted the inches back to feet by dividing the sum of the sides by 12.

A = 28.26 sq yds

Step-by-step explanation:

diameter (D) = 6 yds

radius (r) = D/2 = 3 yds

A = πr^2

= (3.14)(3 yds)^2

= 28.26 sq. yds

Answer:

780

Step-by-step explanation:

24 - 67 = - 43

- 43 - 88 = - 131

- 131 + 77 - 77 = - 131

- 131 + 78 = - 53

- 53 - 55 = - 108

- 108 + 888 = 780

=========================================================

Explanation:

We have c^2 + 2c, where 2 is the coefficient of the c term

This halves to 2/2 = 1, and then we square that to get 1^2 = 1.

Adding 1 to c^2+2c will result in c^2+2c+1, allowing it to be factored. This is because it's a perfect square

The rule we use is

(a+b)^2 = a^2 + 2ab + b^2

Answer: c

3295000

Step-by-step explanation:

3295×999+3295

3295 * 999 = 3291705

3295×999+3295

3295 * 999 + 3295

3291705 + 3295 = 3295000

Answer:

0.189

4.525

Step-by-step explanation:

v/1 + 2/v + 4v/3 = 11

we can eliminate denominators if we distribute 3v to each term:

3v(v/1 + 2/v + 4v/3) = 3v(11)

3v² + 6 + 4v² = 33v

7v² - 33v + 6 = 0

factor this trinomial:

there are no factors of 6 that would add to -33 so we can use the quadratic formula to solve:  (-b ± √b²-4ac) / 2a

a = 7

b = -33

c = 6

[33 ± √(-33)² - 4(7)(6)] / 2(7)

(33 ± √1089 - 168) / 14

(33 ± √921) / 14

(33 ± 30.35) / 14

(33+30.35) / 14 =  4.525

(33-30.35) / 14 =  0.189

Answer:

X= -12 Y=10

Step-by-step explanation:

The solution is, Solve of the system of equations.

9x+11y=2 & 3x+4y=4 is, x = -12 & y =10.

An equation is a  mathematical statement that is made up of two expressions connected by an equal sign.  In its simplest form in algebra, the definition of an equation is a mathematical statement that shows that two mathematical expressions are equal. For instance, 3x + 5 = 14 is an equation, in which 3x + 5 and 14 are two expressions separated by an 'equal' sign.

here, we have,

given that, the system of equations.

9x+11y=2 .......(1)

3x+4y=4 ...........(2)

now, for solving, multiply (2) by 3 & subtract from (1),

we get,

9x + 11y =  2

9x + 12y = 12

---------------------

y= 10

from (1), we get, x = -12

Hence, The solution is, Solve of the system of equations.

9x+11y=2 & 3x+4y=4 is, x = -12 & y =10.

Answer:

The median is 6.

Step-by-step explanation:

To find the median, put the numbers in order then find the middle number. In this data set, there are 2 numbers, so you add those 2 and divide by 2.

5+7 equals 12. 12 divided by 2 is 6.

Answer:

10m = height

Step-by-step explanation:

Volume of a Cylinder = πr²(h), where r is the radius and h is the heigh of the circle, therefore;

=> 1000π = π(10)²(h)

=> 1000π = 100π(h)

=> 1000π/100π = h

=> 10 = h

Answer:

750 monkeys (probable chance)

Step-by-step explanation:

100 : 50

100 square miles to a 2:1 ratio of 50 monkeys

Simply, insert the new area into the ratio to get the result.

1500 ---> 2:1

1500/2 = 750

1500:750

Thus, there would probably be 750 monkeys inhabiting a 1,500 square mile jungle.

Answer:

12 and 10

Step-by-step explanation:

Answer:

11 and 21

Step-by-step explanation:

Let the first number equal x. If the first number, the second number is ten more, and can represented as x + 10. Now, the sum is 32, so we can add the two numbers to get 32:

x + x + 10 = 32

2x + 10 = 32

2x = 22

x = 11

If the first number 11, the second number is 10 more, and therefore is 21.
