Answer:

The angle that us congruent to angle 6 is angle 2 and angle 3.

Answer:

what the questionnnnnn

Answer:

2 feet

Step-by-step explanation:

This is because you have to use ratios:

18:12 :: 3:x

you can then figure out 18/12=1.5, so you have to figure out what what 1/1.5 or 2/3 of what 3 is.  you then multiply 3 by 2/3 and get 2 feet

Answer:

2 ft

Step-by-step explanation:

use cross multiplication

12 is to 18 as x is to 3

12 / 18 = x / 3

12 × 3 = 18x

now solve for x

36 = 18x

divide by 18

2 = x

So a 3 ft baby elephant casts a 2 ft shadow

Answer:

$0.5

Step-by-step explanation:

Given data

Cost of 5 pencils= $2.50

Required

The cost per pencil

The cost per pencil is

Cost of 5 pencils divided by 5

=2.5/5

=$0.5

This is the constant of proportionality

For any number of pencils x

The cost is

Cost =0.5x

Hence the cost of one pencil is $0.5

Answer:

[tex]\frac{dy}{dx}[/tex] = - [tex]\frac{18x}{(3x^2+1)^4}[/tex]

Step-by-step explanation:

Differentiate using the chain rule

Given

y = f(g(x)) , then

[tex]\frac{dy}{dx}[/tex] = f'(g(x) × g'(x)

Given

y = [tex]\frac{1}{(3x^2+1)^3}[/tex] = [tex](3x^2+1)^{-3}[/tex] , then

[tex]\frac{dy}{dx}[/tex] = - 3[tex](3x^2+1)^{-4}[/tex] × [tex]\frac{d}{dx}[/tex] (3x² + 1 )

    = - 3[tex](3x^2+1)^{-4}[/tex] × 6x

    = - [tex]\frac{18x}{(3x^2+1)^{4} }[/tex]

Answer:

they need 130 per day signature

Answer:

0

Step-by-step explanation:

to simplify distribute the negative sign

x + 4 - (x - 4)

x + 4 - x + 4; which cancels the x and 4

0

Answer:

8

Step-by-step explanation:

-(x-4) : -x+4

x+4 -x+4

simplify: x+4 -x+4=8

Answer:

Step-by-step explanation:

first we are told that side and ae and a f are the same

so that means one side of each triangle is the same

next we are told that that the lines coming off of those sides are both right angles. so we know these are both right triangles

and b/c both of those angle are right angles... the sides ab and ac have to also be the same length.. or the angle could not be a right angle

therefore since two sides are the same length then all 3 must be the same lengths

and b/c all three are the same these two triangles are the same .. congruent

Answer:

6 13/14

Step-by-step explanation:

Answer: You simply square the linear scale factor 6 and we get 6^2 = 6*6 = 36

You can think of a square with sides of 2 by 2, so the area is 4 If you multiply each dimension by 6, then the square is now 12 by 12 and the new area is 144.

Step-by-step explanation:

1/2 base x height

(40 divided by 2) x 30 =600m^2

Step-by-step explanation:

semi perimeter(s) = (30+40+50)/2

= 60

a=30 b=40 c=50

area = √s(s-a)(s-b)(s-c)

= √60(60-30)(60-40)(60-50)

= √60×30×20×10

=√360000

=600

Answer:

5 more man should be added

Step-by-step explanation:

Inverse Proportion

The time needed to complete a job is inversely proportional to the number of men working on it.

It means the more men working, the less time needed to complete the job.

We know 20 men can complete the job in 15 days. If the job must be completed in 12 days, then more men are needed, thus the number of men needed is:

[tex]20*\frac{15}{12}=\frac{300}{12}=25[/tex]

25 men are needed which means 25-20 = 5 more men should be added.

5 more man should be added

Answer:

8/35

Answer:

I'm pretty sure it's 16, but my initial thought was 17 from a pattern, but 16 just seems so random.

The pattern was the first number plus the number 2 times before it.

Ex: 3 + 4 = 7

3 + 6 = 9

3 + 7 = 10

This question is hard. Sorry if I'm wrong.

Answer:

x is greater than or equal to 3. x ≥ 3

Step-by-step explanation:

Answer:

x ≥ 3

The arrow goes to the right, the dot is shaded in and x is at 3.

Therefore, x ≥ 3.

Answer:

w = 42

Step-by-step explanation:

-w/6 + 9 = 2

subtract 9 from both sides

-w/6 + 9 - 9 = 2 - 9

-w/6 = 2 - 9

-w/6 = -7

multiply both sides by -6

-w/6 * -6 = -7 * -6

w = -7 * -6

w = 42

Answer:

4x-18y-18/12

Step-by-step explanation:

x/3 - 2(y+1)/4

1. Find the Least Common Multiple for the denominators (in this case it is 12)

4x/12 - 6(3y+3)/12

2. Use PEMDAS

4x/12 - 18y+18/12

3. Distribute the arithmetic sign

4x/12 + -18y-18/12

4. Combine the fractions

4x-18y-18/12
