Answer:

0 < x < 1/3

Step-by-step explanation:

Hello! The answer I provided is correct, you know this because any value you can use for X that is in between 0 and 1/3 would make the inequality true.

Step-by-step explanation:

you work with it like with regular equations :

Answer:

24

Step-by-step explanation:

Answer:110

Step-by-step explanation:

24.2/x = 22/100

Where x is the number we are looking for

cross multiply

24.2*100 = 2420

22*x=22x

22x=2420

22x/22=2420/22

x= 110

so 24.2 is 22% of 110

Answer:

If 22% × 110 = 24.2 => Divide 24.2 by 110And see if we get as a result: 22% Note: Multiply a number by the fraction 100/100, and its value doesn't change.

I agree with the statement because primary function of chemical nomenclature is to ensure that a spoken or written chemical name leaves no ambiguity concerning which chemical compound the name refers to: each chemical name should refer to a single substance.  The first separation of importance is to distinguish between inorganic and organic compounds.

Answer:

x = 17

Step-by-step explanation:

The two given angles are supplementary angles, but also all angles on a straight light must add up to 180°:

3x + 14 + 7x - 4 = 180

Add like terms

3x + 7x + 14 - 4 = 180

10x + 10 = 180

Subtract 10 from both sides to isolate 10x:

10x + 10 - 10 = 180 - 10

10x = 170

Divide both sides by 10:

10x ÷ 10 = 170 ÷ 10

x = 17

Answer:

a) 92 m

b) 74 cm

Step-by-step explanation:

a)

2(length) + 2(width) = perimeter

2(x) + 2(73) = 330 m

2x + 146 = 330

2x = 184

x = 92 m

b)

length * width = area

85 * x = 6290 cm²

85x = 6290

x = 74 cm

Answer:

Step-by-step explanation:

The easiest way to answer your question is to graph it. I've enclosed a graph for you. The answer to the  question as it is asked is y ≥ 2.

The answer to your question (which is a much more interesting question) is that there is no 0. A zero of a function must touch or intersect the x axis.

Incase you didn't get the notification on your other post.

Answer:

It's D)

C is incorrect because the constant is + 1, not - 8

A is incorrect because the f doesn't go up by 2 for every x value

B is incorrect because 2/3 * 2 would be 4/3 which is 1 1/3, which is wrong because g goes up by 2 every x.

D is correct because f goes up by 1/3, and the y-intercept is 1 (Where the line meets when the x-axis is 0) and 1/3 * 6x is 6x/3 which is 2x, then add the y-intercept to the equation, which should be 2x + 1

Answer:

Step-by-step explanation:

if <C=90 and <B = 30, then <A=60 (because <A+<B+<C=180, as ABC is a triangle)

if CM is a angle bisector then it divides <C in half, so <ACM=<MCB=45

since <ACM=45;

         <A = 60;

then  <AMC = 180-(45+60),

         <AMC = 180-105,

         <AMC = 75.

Step-by-step explanation:

Answer:

D.

Step-by-step explanation:

An excluded value often comes from a zero in the denominator.

Set each denominator equal to zero creating an equation in x. If there is a solution to the equation, then there are excluded values. If the equation has no solution, then there are no excluded values.

A.

2x^2 = 0

x = 0

excluded value

B.

3x + 3 = 0

3x = -3

x = -1

excluded value

C.

x² - 7 = 0

x² = 7

x = √7 or x = -√7

excluded values

D.

-x² - 5 = 0

x² = -5

x = √(-5) or x = -√(-5)

There is no real solution for x.

no excluded values

Answer: D

Answer:

x = 13

angle A = 97degrees

Step-by-step explanation:

TO GET "x=13"

since the angle is an alternate angle , it adds up to 180deg so :-

A+B =180

6x + 5 + 4x + 45 = 180

then u add the like terms :-

10x + 50 = 180

then u substitute:-

10x = 180-50

10x = 130

10x÷10 = 130 ÷10 ( this is to cancel the 10 )

x = 13

___________________________________________________________________

TO GET "A=97"

since we need the magnitude of A, we need to .... um I dunno how to explain this soo.....

the equation for A = 6x + 5

180 is the sum of the 2 angles so :-

180 - 5 - (13 × 6) 13×6 is because x=13

180 - 5 - 78= 97

I subtracted these since we need to cancel to get to an answer

I hope u get it.... sorry if u can't understand

and sorry once again if this answer.... I did it in a rush

The number of trees calamansi have is 488 trees. The number of tree pomelo trees have in Jacintos farm is 305 trees

From the given information, we learnt that:

The ratio of the calamansi and  pomelo trees in Jacintos farm  = 8:5

If the total number of the ratio = 8 + 5 = 13

The proportion of the calamansi can be estimated as:

= (8/13) × 793

= 488 trees

The proportion of pomelo trees is:

= (5/13) × 793

= 305 trees

Therefore, we can conclude that the number of trees calamansi have is 488 trees and the number of tree pomelo trees have in Jacintos farm is 305 trees.

There are  488 calamansi trees

There are 305 jacintos trees

Let x represent the number of calamansi trees

Let y represent the number of Pomelo trees

8 +5= 13

793/13

= 61

8(61)= 488

5(61)= 305

Hence there are 488 calamansi trees and 305 jacintos trees

Answer:

Option A: y = 6x + 11

Step-by-step explanation:

Given the linear equation in point-slope form, y - 5 = 6(x + 1), and that we must determine its equivalent slope-intercept form, y = mx + b:

First, we must distribute 6 into the parenthesis on the right-hand side of the equation:

y - 5 = 6(x + 1)

y - 5 = 6x + 6

Lastly, we must add 5 to both sides of the equation to isolate y:

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

y = 6x + 11

Therefore, the slope-intercept form is: y = 6x + 11, which matches Option A.

Step-by-step explanation:

Root of the function, where y = 0

f(x) = x² + 2x - 1

0 = x² + 2x - 1

x² + 2x - 1 = 0

x² + 2x = 1

x² + 2x + 1 = 1 + 1

(x + 1)² = 2

x + 1 = ±√2

x = -1 ± √2

Roots → x = -1 ± √2

I think it is 21 since the relationship between 4 and 12 4 * 3 is equal to 12 so I did the same for each side but angles don't change so 7*3=21

Answer:

B) 2,000.

Step-by-step explanation:

As the mean is 6000 the total number of students = 5*6000

= 30,000.

If graduates are excluded we have 4*7000 = 28,000 students.

So the number at graduate level

=  30,000 - 28,000

= 2,000.
