Answers

[ -4, 5 ]

notice the brackets, as opposed to parentheses.

the brackets mean, -4 is a bound and it is included in the range, and 5 is the other bound and 5 is also included in the range too.

so, whatever number "x" is, we know that is between -4 and 5, so it could be -3, -2, 1, 4 or such.

keeping in mind that, for the negative side of the numbers, the closer to 0, the greater the number, therefore, -4 is greater than -5 and is also greater than -1,000,000, because -4 is closer to 0 than those two.

so, "x" is greater than -4, and includes it, but is also less than 5, but it can be 5 too.

12^2 +b^2 = 20^2 because of the Pythagorean theorem

B=16

Answer:

Option B : 16

Step-by-step explanation:

Refer the attached file

Given :

In ΔABC , AB = b , BC = 12  , AC= 20

To Find : value of b i.e. Length of AB

Solution:

Since we are given a right angles triangle so we can use Pythagoras theorem i.e.

[tex](Hypotenuse)^{2} =(Perpendicular)^{2} +(Base)^{2} [/tex]    ---(a)

Now in a given triangle AB is Perpendicular , BC is Base and AC is Hypotenuse.

So, putting values in (a)

[tex](AC)^{2} =(AB)^{2} +(BC)^{2} [/tex]

[tex](20)^{2} =(b)^{2} +(12)^{2} [/tex]

[tex]400 =(AB)^{2} +144 [/tex]

[tex]400-144  =(b)^{2} [/tex]

[tex]256 =(b)^{2} [/tex]

[tex]\sqrt{256} =b[/tex]

[tex]16=b[/tex]

Thus the value of b is 6

Hence Option B is correct.

Answers

-10y + 9x = - 9....A
10y + 5x = - 5.....B

You should see right away that -10y and 10y cancel out.

We are left with

14x = -14

x = -14/14

x = -1

Plug x = -1 into EITHER equation A or B to find y.

I will use equation A.

-10y + 9(-1) = - 9

-10y - 9 = - 9

-10y = - 9 + 9

- 10y = 0

y = 0/-10

y = 0

URGENT NEEDS TO ME SUBMITTED BY MIDNIGHT!! The ratio of girls to boys in Mr. Hansen’s class is 4:5. The ratio of girls to boys in Ms. Luna’s class is 8:10. Which equation correctly compares these ratios?

Answers

If the ratio of girls to boys in Mr. Hansen's class is 4:5, and the ratio of girls to boys in Ms. Luna's class is 8:10, then the equation that correctly compares the ratio of both Mr. Hansen's class and Ms. Luna's class are 4/5 = 8/10.

4:5 ≡ 8: 10 is the correct way to compares these ratios.

What are equivalent?

" Equivalent means when two or more things have same value but different expression."

According to the question,

Ratio of girls to boys in Mr. Hansen's class = 4 : 5

Ratio of girls to boys in Ms. Luna's class = 8 : 10

Compare both the ratio's we get,

As

[tex]\frac{8}{10} =\frac{2}{2} * \frac{4}{5}[/tex]

Therefore,

4 : 5 ≡ 8 : 10

Hence, 4:5 ≡ 8: 10 is the correct way to compares these ratios.

The sides of an equilateral triangle are increasing at a rate of 10 cm/min. at what rate is the area of the triangle increasing when the sides are 30 cm long?

Answers

Area of a triangle is given by

[tex]Area= \frac{1}{2} ab\sin C= \frac{1}{2} s^2\sin C[/tex]

Since the sides of an equilateral triangle are equal.

Differentiating the area of the triangle, we have:

[tex] \frac{dA}{dt} = \frac{dA}{ds} \cdot \frac{ds}{dt} =(s\sin C) \frac{ds}{dt} [/tex]

where

[tex] \frac{ds}{dt} =10\,cm/min \\ s=30 \, cm[/tex]

[tex]\therefore \frac{dA}{dt} =(30\sin60)\times10=300\sin60=259.8\, cm^2/min[/tex]

Therefore, the rate is the area of the triangle increasing when the sides are 30 cm long is 259.8 cm^2 / min

Ali,s dod weighs 8 times as many as her cat.Together, the two pets weigh 54 pounds.HOW much does Ali's dog weigh

Answers

Ali dog = 8units
cat = 1 unit
total = 9 units
9u= 54
1u=6
8u= 48 pounds
There are a few steps in order to get the correct answer.

First you have to look at the facts about what we know:
 - her dog is 8 times as much as her cat
 - her dog and cat together equal 54 pounds

Now you need to create the equations based on what you know:
Let's say x is her dog and y is her cat

x+y=54  (both dog & cat equal 54)
x=8y  (dog is 8 times as much as cat)

Step 1 -
Put in what we know x is for our first equation and solve for y (cat):

8y+y=54  (Combine like terms)
 9y=54  (Divide by 9 on each side to get y by itself)
  y=6
Now we have solved for y, but we still don't know what x is.

Step 2 - 
Put in y into our first equation to solve for x (dog): 

x+6=54  (Subtract 6 from both sides to get x by itself)
 x=48 
Now we have solved for x also. So now we have both x and y.

But to check our work we just have to put the numbers into the original equations: 

x+y=54  ---->  48+6=54  (Correct)
 x=8y  ---->  48=8(6)  (Correct)

You now have your final answer. Ali's dog weighs 48 pounds and her cat weighs 6 pounds.

Transitive property: if 3x plus y equals 7 and 7 equals 5x minus 2y then

Answers

3x + y = 7
7 = 5x - 2y

THEN 3x + y = 5x - 2y ... it's like you're taking out the middle man "7"

Transitive property states that if x = y and y = z then x = z.

3x + y = 7 and 7 = 5x - 2y

Using the transitive property we get,

3x + y = 5x - 2y.

What is transitive property?

It states that if x, y and z are the three quantities, and if x is related to y by a rule, and y is related to z by the same rule, then we can say x is related to z by the same rule.

Example:

x + 1 = 2 and 2 = x + 9 then x + 1 = x + 9

We have,

3x + y = 7 and 7 = 5x - 2y

Using transitive property we can say that,

3x + y = 5x - 2y

Thus using the transitive property we have,

3x + y = 5x - 2y.

The product of two numbers is 44. find the sum of the two numbers s(x) as a function of one of the numbers, x. s(x)

Answers

Call the numbers x and y. According to the first sentence, xy = 44. You can rearrange to solve for y: y = 44/x. The sum of the numbers, s(x), is x + y, but we just found a way of expressing y in terms of x. Therefore: the sum expressed as a function of one of the numbers (x) is:

s(x) = x + 44/x
