1) 2^2/5^2
2) 5/2^2
3) 5/2
4) 5^2/2

Answers

Its: 3) 5/2

Explanation:

too complicated

It’s 3) 5/3
Explanation:

5^-3 x 2^2 x 5^6
_____________

2^3 x 5^2

Now workout the numerator and the denominator.
Multiplication means add the indices.
Same denominators so add up the indices, 5^-3 x 5^6 –> -3 + 6 = 3

5^3 x 2^2
________

2^3 x 5^2

Divide means take the indices away.(Same base number only)
5^3 divided by 5^2 —> 3-2 = 1
5^1 = 5

2^2 divided by 2^3 —> 2-3 = -1
2^-1 = 1/2 or 0.5
Then the answer is 5/0.5 which is 2.5
And 5/2 is equal to 2.5 so it must be number 3

or you can do 20 times 5 which is 100 and 8 times 5 which is 40 so thats why 40/100

BRAINLIEST PLEASE !!! :)

8 meters is equivalent to the fraction 2/5 of 20 meters.

Given that:

Given part, 8 meters

And whole part, 20 meters

To express 8 meters as a fraction of 20 meters, simply divide the given part by the whole.

The formula is given below,

Fraction = (Part) / (Whole)

Put the given values in above formula and calculated as:

Fraction = (Part) / (Whole)

Fraction = 8 m / 20 m

Now, simplify the fraction by canceling out the common factor of 4:

Fraction = (8 m / 4) / (20 m / 4)

Fraction = 2 m / 5 m

So, 8 meters is equivalent to the fraction 2/5 of 20 meters.

Answers

Answer:  D) 8

Explanation:

The green, light blue, and red bars all indicate scores that are 70 or higher.

We add up the heights of those bars to find out how many people passed.

green bar = height of 2light blue bar = height of 5red bar = height of 1

So 2+5+1 = 8 people passed.

Unfortunately 2 people (dark blue bar) got below 70 so they didn't pass.

Please answer the following questions 1 2 and 3 with showing your work fully!

Answers

Answer:

1. Point of intersection = (4, 360)

2. (4, 360) number of hours and the total cost of the repairs is the same for both repair shops

3. Amy's Auto Repair: $280

Step-by-step explanation:

1.  y = 100 + 65x    and    y = 40 + 80x

Equate the equations and solve for x:

y = y ⇒ 100 + 65x = 40 + 80x

subtract 65x from both sides ⇒ 100 = 40 + 15x

subtract 40 from both sides ⇒ 60 = 15x

divide both sides by 15 ⇒ 4 = x

Therefore, x = 4

Substitute x = 4 into either of the equations to find y:

⇒ y = 40 + (80 x 4) = 40 + 320 = 360

Point of intersection = (4, 360)

2. The two lines intersect at (4, 360)

In this context, the point of intersection is where the number of hours and the total cost of the repairs is the same for both repair shops.

3. Substitute x = 3 into the equations and compare:

Mike's repair shop:  y = 100 + (65 x 3) = 295

Amy's auto repair: y = 40 + (80 x 3) = 280

Therefore, Amy's Auto Repair is the cheapest (as 280 < 295) and the cost is $280.

What multiplies to give you 15 and adds to give you -8?

Answers

Answer:

-5 and -3 because if you multiply both the answer is 15 and if you plus both the answer is -8.

Answer:

Step-by-step explanation:
Take one number as x.

Given,
x + ? = -8
? = - 8 - x

So, second number is -8 - x

Now,
x ( -8 - x) = 15
-8x - x² = 15
-8x - x² - 15 = 0
-x² - 8x - 15 = 0
(-x² - 3x) + (5x - 15) = 0
x (-x - 3) + 5 (-x - 3) = 0
(- x - 3)(x + 5) = 0

Answer is D:45

We are able to figure this out because we know that these are opposite angles, which means that we know 50 = (3y +5), and 70 = (2x +4)

A variable next to a number means we have to multiply them. We take 50-5 and get 45. What times 3 is 45? 15!

70-4= 66, 2 times what equals 66? 33!

That just leaves us to find the sum of the two, which means we have to add 33+15 which equals 45!

(SAT Prep) If the lengths of two sides of a triangle measure 8 and 13 what could the length of the third side measure
(A) 6

(B) 21

(C) 3

(D) 4
Hint its not D.

Answers

Answer:

A)6

Step-by-step explanation:

Use the triangle inequality theorem, which states that the third side of a triangle can not be greater than or equal to the sum of the other two sides, and can be no less than the or equal to the difference of the two other sides.

The sum is 8+13=21

The difference is 13-8=5

So if we call our third side x, then

[tex]5

If the lengths of two sides of a triangle measure 8 and 13 units, using triangle inequality theorem, the length of the third side could be 6 units.

What is triangle inequality theorem?

The triangle inequality theorem describes the relationship between the three sides of a triangle. According to this theorem, for any triangle, the sum of lengths of two sides is always greater than the third side.

Given the two sides be 8 and 13 units.

Let the third side be x units.

First,

8 + 13 > x

21 > x

x < 21

Second,

8 + x > 13

x > 5

Third,

13 + x > 8

True for all values of x.

So,

5 < x < 21

From the given options, only 6 satisfies our condition.
