Answer:

c. 7.6 > 7.575

Step-by-step explanation

The ones place is the same, so you move onto the digit in the next place. 6 is more than 5 so 7.6 is greater and that's what it says.

You can apply this to the rest and see they are all untrue, remember, when it's negative the smaller digit means it's greater

Answer:

the answer is c. 7.6 > 7.575 have a good day hope this helps

Step-by-step explanation:

Answer:

the answer would be the last one because 275% equal 2.75 if you decide it

Answer: false, false, true, true, true

Step-by-step explanation:

Answer:

The acute interior angles of a right triangle are complementary.

Step-by-step explanation:

that if an acute angle and the obtuse angle is added, its sum is 180 degrees. ⟹ (5θ + 4°) + (θ – 2°) + (3θ + 7°) = 180°.  A supplementary angle can be composed of one a cute angle and another obtuse angle. Thanks 0. y = 180 -x. range of x = [1º 89º] then range of y is [91º 179º] so this proves that always the supplementary to acute angle is always obtuse.

I hope this helped have a good rest of your day  

Answer:

Always

Step-by-step explanation:

Let's name the acute angles x and y,

We are given that it's a right triangle so one angle is 90 degrees.

Sums of angles in a triangle add up to 180 degrees.

So,

x+y+90=180

x+y=90

The acute angles add up to 90 degrees so they are complementary.

Answer:

The first period

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

That would be 6 4/9 plus 5/9.  Note that 4/9 + 5/9 = 9/9 = 1.

Therefore, 6 4/9 plus 5/9 = 6 4/9 + 5/9 = 6 9/9 = 7

Answer:

A.

Step-by-step explanation:

We know that 5/9 is more than 50%. This is because 5 is more than half of 9. Therefore, the answer is A.

If this has helped please mark as brainliest

Answer:

A.

Step-by-step explanation:

If you look up 5/9, you will find that 5/9 is equal to 0.55 repeating which is greater then 0.497

5b - 5 + 10, when b = 5.

(5×5) - 5 + 10

= 25 - 5 + 10

= 20 + 10

Answer:

2x+28≤23

Step-by-step explanation:

The sum of a number times 2 and 28 is

2x+28

is at most 23

≤23

So it is 2x+28≤23

Answer: should be 200

Step-by-step explanation:

Answer:

81  

Step-by-step explanation:

if the height is 9 you just have to multiply 9x9 and u get the answer 81

So, (578÷2)(100÷2) = 28950 when reduced to the simplest form. As the numerator is greater than the denominator, we have an IMPROPER fraction, so we can also express it as a MIXED NUMBER, thus 578100 is also equal to 53950 when expressed as a mixed number.

Answer:

39/50

Step-by-step explanation:

--Answer--

1. $85

2. $15

--Explanation--

1. 15% off of 100 just means moving the decimal in 15 over by 2 to the left.

From there, multiply 100 x 0.15.

Then you get 15, so that's how much tax you are paying. Meaning Subtract 15 from 100 to get the price it originally was before tax. 100 - 15 = 85.

2. $15 dollars tax from moving decimal 2 to the left of 15%.

Answer:

B

Step-by-step explanation:

Dilation is changing it and it would not move Quadrants. Reflection would change the slope and I do not know if you can even do it from one to four (I also don't know which one is 1 and which one is 4).

All I know is that translation moves it without changing anything. It is a transformation bc it is translation.

Answer:

B

Step-by-step explanation:

a translation doesn’t change the size, rotation, or anything. it just moves

so B makes the most sense

Answer:

Start by finding the mean of the data set.

Find the absolute value of the difference between each data value and the mean.

Find the sum of the absolute values and divide the sum by the number of data values.

Step-by-step explanation:

Before I Also Didn't Know How To Find M.A.D Then I Learned.

Answer:

after finding the mean, subtract the mean from each given number, but have it to where it never goes below zero. from there you take your new numbers and redo the same process as mean and the number you get after that is your M.A.D

Answer: 7/8 inches

Step-by-step explanation: There are 3 x's for 1/8 so that is 3/8. There are 2 x's for 1/4 which is 2/4, but you need to have the same denominator so you do 2 times the numerator and denimator which is 4/8. 3/8 + 4/8 = 7/8

Answer:

2. Not Right Triangle

3. Not Right Triangle

Step-by-step explanation:

1. 28² + 45² = 2809 --> 53² = 2809

2. 6² + 6² = 72 --> 8² = 64

3. 4² + 10² = 116 --> 12² = 144

Answer:

Step-by-step explanation:

Use the given (x, y) coordinates in the transformation formula and simplify.

This transformation translates each point right 1 and down 6.

  (x, y) ⇒ (x+1, y-6)

  P(-5, 4) ⇒ P'(-5+1, 4-6) = P'(-4, -2)

  Q(1, 4) ⇒ Q'(1+1, 4-6) = Q'(2, -2)

  R(1, 1) ⇒ R'(1+1, 1-6) = R'(2, -5)

Additional comment

The notation is a bit unconventional. It appears that P' (P prime) is being represented as P^I, which would be interpreted as P with an exponent of I (eye). The "prime" is usually an apostrophe. P' conventionally means the image of point P after some transformation.
