Brenda completes her sixth hiking trail in a state park. A park ranger tells her that she has hiked 25% of the trails. How many trails are there to hike in the state park?

Answer:

an answer is precise when it is an exact number like 10, 2, or 123.

An answer is approximate when the decimal numbers are so close that could round it, and the rounded number would be equivalent to the original number. ex: 10.98 = 11

Answer:

(−3)2

Step-by-step explanation:

Answer: (x-3)2

Step-by-step explanation:

Answer:

156

Step-by-step explanation:

Hey There!

The angle that is equal to 156 and the angle labeled x are corresponding angles meaning that they are congruent angles. Therefore x=156

Answer:

yes; The triangles are congruent by hypotenuse-angle congruence.

Step-by-step explanation:

Answer: yes Question 6

There is not enough information to determine congruency

Question 9

yes; The triangles are congruent by hypotenuse-leg congruence

Step-by-step explanation:

* Lets revise the cases of congruence  

- SSS  ⇒ 3 sides in the 1st Δ ≅ 3 sides in the 2nd Δ

- SAS ⇒ 2 sides and including angle in the 1st Δ ≅ 2 sides and  

including angle in the 2nd Δ  

- ASA ⇒ 2 angles and the side whose joining them in the 1st Δ  

≅ 2 angles and the side whose joining them in the 2nd Δ

- AAS ⇒ 2 angles and one side in the first triangle ≅ 2 angles  

and one side in the 2ndΔ

- HL ⇒ hypotenuse - leg of the first right angle triangle ≅ hypotenuse

- leg of the 2nd right angle Δ

- HA ⇒ hypotenuse - angle of the first right angle triangle ≅ hypotenuse

- angle of the 2nd right angle Δ

- LL ⇒ leg - leg of the first right angle triangle ≅ leg - leg of the

2nd right angle Δ

* Now lets solve the problem

# Question 6

- There are two right angle triangles

- They have two different legs

- There is no mention abut legs equal each other

- There is no mention about hypotenuses equal each other

- There is no mention about acute angels equal each other

∴ There is not enough information to determine congruency

# Question 9

- There are two right angle triangles

- Their hypotenuse is common

- There are two corresponding legs are equal

∵ The hypotenuse is a common in the two right triangles

∵ Two corresponding legs are equal

- By using hypotenuse-leg congruence

∴ yes; The triangles are congruent by hypotenuse-leg congruence

Step-by-step explanation:

Property 5

RHS Criterion for Congruence

Explaining the congruence of triangles using RHS Criterion of Congruence

RHS Criterion stands for Right Angle-Hypotenuse-Side Criterion.

Under this criterion, if the hypotenuse and side of one right-angled triangle are equal to the hypotenuse and the corresponding side of another right-angled triangle, the two triangles are congruent.

Important Notes

Two figures are congruent if they have the same shape and size.

Two angles are congruent if their measures are exactly the same.

Two triangles with equal corresponding angles may not be congruent to each other because one triangle might be an enlarged copy of the other. Hence, there is no AAA Criterion for Congruence.

Hope this helps have a nice day❤️

Answer:

x=20

Step-by-step explanation:

ok so that is a pentagon and if you didnt know all of the angles in a pentagon add up to equal 540

so we setup an equation which would be

7x+4x+5+4x+10+5x-5+6x+10=540 and now we just solve for x

step 1 combine like terms

7x+4x=11x

11x+4x=15x

15x+5x=20x

20x+6x=26x

5+10=15

15-5=10

10+10=20

now we have

20+26x=540

step 2 subtract each side by 20

20-20 cancels out

540-20=520

now we have 26x=540

the final step is to divide each side by 26

26/26 cancels out

540/26=20

x=20

hope this helps :D

Answer:

Both

Step-by-step explanation:

13 = -6(-2)+1

13=13 CORRECT

7 = -6(-1)+1

7=7 CORRECT

Answer:

C

Step-by-step explanation:

y = -6x + 1 so substitute the two answers given x = -1 and x = -2

when x = -1 then y = -6(-1) + 1 so y = 7 so (-1,7)

when x = -2 then y = -6(-2) + 1 so y = 13 (-2,13)

Answer:

17 / 18

Step-by-step explanation:

1/9 + 5/6 needs to be converted to a different equivalent fraction so that the denominators are the same, so;

1/9 = 2/18 and 5/6 = 15/18

2/18 + 15/18 = 17/18!

Answer:

x=15 degrees

Step-by-step explanation:

You know that the right angle is split in half to 45 degrees and 3x degrees. Because a right angle is equal to 90 degrees, 3x has to be equal to 45. Therefore, the equation will be 3x=45. You want to make x equal one so you have to divide 3 by each side. The equation will be x=45/3. Simplify that to get x=15. Therefore, x=15 degrees.

If this has helped you, please mark this answer as the brainliest

(7x - 23)° + (11x + 23)° = 180°

7x - 23° + 11x + 23° = 180°

18x = 180° / : 18

x = 10°

Answer: 8

Step-by-step explanation:

Answer: 8 pizzas.

Step-by-step explanation:If she is ordering 4 pizzas for 15 people then that simply means that the fraction is 4/15, 15*2 is 30, so that means that our next fraction (Equivalent fraction) will be like this 4/15 = -/30. What ever. Happens to the numerator must happen to the denominator and vice versa. So 4*2 is 8. So the answer is 8.

Answer:

Lateral surface area of the storage shed = 336 ft²

Step-by-step explanation:

The shed is in the shape of a rectangular prism. The lateral surface area of the storage shed can be calculated below. The lateral area is the sides of the prism.

lateral area of a rectangular prism = 2h (l + w)

where

l = length

h = height

w = width

h = 8 ft

l = 14 ft

w = 7 ft

lateral area of a rectangular prism = 2h (l + w)

lateral area of a rectangular prism = 2 × 8 × (14 + 7)

lateral area of a rectangular prism = 16 (21)

lateral area of a rectangular prism = 336 ft²

Lateral surface area of the storage shed = 336 ft²

Answer:

Folow the steps to learn what transformations were determined.

Step-by-step explanation:

First we would have to graph the parent function which is f(x) = x^2. Start by finding your x and y values. Find the y values by plugging in the x values into the parent function.

X    Y

2    4

1     1

0    0

-1     1

-2    4

Once these points are plotted you can start determining what are the transformations. Find the difference between the parent function and f(x) = (x + 4)^2 + 2 by looking below.

Vertical Shifts:

f(x) + c moves up,

f(x) - c moves down.

Horizontal Shifts:

f(x + c) moves left,

f(x - c) moves right.

The parent function has to be transformed left 4 and up 2. In order to do this shift each point from earlier left 4 and then up 2. In conclusion you will have two functions graphed (parent function and the transformed function).

Answer:

l = 6 cm

Step-by-step explanation:

Given that,

The volume of a cuboid, V = 384 cm³

The base and height are 8 cm

We need to find the length of the cuboid. The formula for the volume of a cylinder is given by :

[tex]V=l\times b\times h\\\\l=\dfrac{V}{bh}\\\\l=\dfrac{384}{8\times 8}\\\\l=6\ cm[/tex]

So, the length of the cuboid is 6 cm.

Answer:

(3,-2)

Step-by-step explanation:

The solution is, there is  no solution to the system.

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 the equation y=-2x+1

and given another equation y=mx+b in order for us to have no solution we must guarantee that both lines do not intersect.

Recall that m is the slope of the second equation and b the y-intercept. To guarantee that both lines don't intersect, they must be parallel.

To have this result, we must have that they have the same slope but different y intercept.

That is take m = -2 and b any value different to +1. For example, the b = 6.

So, y = -2x+6 = -2(x-3) is another equation that gives no solution to the system.

#SPJ7

Answer:

the answers B and D are correct

Answer:

B & D

Step-by-step explanation:

It can-t be A, because that would mean 20², which equals 400, would equal 20.

B is correct because even though it's negative, negative times negative = positive, which would mean that (-sqrt of 20)(-sqrt of 20)=20.

C is wrong because sqrt -20 is an imaginary number,which is a completely different topic.

D is correct because it's the same thing as B, but without the 2 negaties cancelling each other out.

E is the same as A, except it's '-20' x '-20', whcih is still 400, which is still wrong

Answer:

they're all wrong, it should be [3,4,7,9]

Step-by-step explanation:

The formula for exponetial equation decay is

[tex]y = a(b) {}^{x} [/tex]

where a is the initial value and b is the decay factor.

A will be 56 since that our initial value.

b will be 0.9 since we are constantly decaying by 0.9.

so our equation is

[tex]y = 56(0.9) {}^{x} [/tex]

Answer:

368 milliliters.

Step-by-step explanation:

Compound A + Compound B = 1 drug

4 + 7 = 1 drug

11 milliliters = 1 drug, so 1012 milliliters = 92 drugs

Multiply the compounds by the amount of drugs, e.g.

4 x 92 = 368 ( Compound A )

7 x 92 = 644 ( Compound B )

368 + 644 = 1012

368 milliliters of Compound A are needed to make 1012 milliliters of the drug.

Hope this helps :)
