what is the value of (-x)-y if x= (-1/5) and y=(-7/15)

Answer:

31136

Step-by-step explanation:

To find the how much an number increased by a percent. Divide the percent by 100. 23/100=0.23.

Then multiply 0.23 by the original number which is 25,314. Which gives us about 5822.

Then since it INCREASED, we are going to add that number it increased to the original. 25314+5822= 31136.

Answer:

Good Luck, hope it helps:)

Step-by-step explanation:

23% of 25,314 = 25,314 x .23 = 5822 then add that to the original population. 25,314 + 5,822 = 31,136

Answer:

A

Step-by-step explanation:

In order to compare all three numbers, you must change them all to have the same form, either all decimal form, all fraction, or all percentages.

The easiest ways to compare are decimal and percentage, as they're practically the same thing. For simplicities sake, though, let's turn all the numbers into decimal.

Since 0.85 is already in decimal form, leave it as it is.

3/4 can be turned into a decimal by putting it into a calculator, but intuitively you should know that it's 0.75. If you don't know a fraction intuitively, you just need to make the fraction into a multiple of denominator 100 and take the numerator. For example:

[tex]\frac{3}{4} * \frac{25}{25} = \frac{75}{100}[/tex]

Numerator is 75.0, now simply move the decimal place up to to get the decimal form 0.75.

91% can be changed into a decimal by moving the decimal place left 2 places. 91.0% turns into 0.91.

Now that you can see the numbers, just rearrange them from least to greatest

0.75<0.85<0.91

equal to A

Answer:

(1,2)

Step-by-step explanation:

Eliminate y-term

[tex](x + 2x) + (4y - 4y) = 9 - 6 \\ 3x = 3 \\ x = \frac{3}{3} \\ x = 1[/tex]

Substitute x = 1 in any given equations.

I choose to substitute in the first equation.

[tex]x + 4y = 9 \\ 1 + 4y = 9 \\ 4y = 9 - 1 \\ 4y = 8 \\ y = \frac{8}{4} \\ y = 2[/tex]

Answer Check

Substitute both x-value and y-value in any given equations.

[tex]x + 4y = 9 \\ 1 + 4(2) = 9 \\ 1 + 8 = 9 \\ 9 = 9[/tex]

The first equation is true. However, we have to check the second equation as well. (Although the first true equarion has already raised the high possibility of right answer.)

[tex]2x - 4y = - 6 \\ 2(1) - 4(2) = - 6 \\ 2 - 8 = - 6 \\ - 6 = - 6[/tex]

Both equations are true for (1,2). Thus the answer is (1,2)

Answer:

The congruent supplements theorem states that 2 angles are supplementary if they add up to 180 degrees, not 90 degrees.

He should have stated the complimentary theorem instead.

Step-by-step explanation:

The correct statement will be,'if ∠1 +∠2 = 180° and if ∠1 +∠3 = 180°, then ∠2 =∠3'.

Given:

∠1 +∠2 = 90° and if ∠1 +∠3 = 90°, then ∠2 =∠3

To find:

The error in Jayden's reasoning

Solution:

According to Congruent Supplements Theorem, the sum of supplementary angles is equal to 180°, not 90°.

[tex]\angle 1 +\angle 2 = 180^o\\\angle 1 +\angle 3 = 180^o\\\text{From this, we can conclude that}:\\\angle 2 = \angle 3[/tex]

The error in Jayden's reasoning was 90°.

The correct statement will be,'if ∠1 +∠2 = 180° and if ∠1 +∠3 = 180°, then ∠2 =∠3'.

Answer:

55 boxes of ice cream

Step-by-step explanation:

Tubs of ice cream : boxes of ice cream = 3 : 1

If the factory makes 165 tubs of ice cream in a day, how many boxes of ice cream bars were made?

Boxes of ice cream made in a day = x

Tubs of ice cream : boxes of ice cream = 165 : x

Equate both ratios to find x

3 : 1 = 165 : x

3/1 = 165/x

Cross product

3 * x = 1 * 165

3x = 165

x = 165/3

x = 55

Boxes of ice cream made in a day = 55

1 1/4 liters of paint

Step-by-step explanation:

Clare is painting some doors that are all the same size. She used 2 liters of paint to cover 1LaTeX: \frac{3}{5}3 5 doors. How many liters of paint are needed for 1 door?

From the above question, we can deduce that:

2 liters of paint covers 1 3/5 doors

Hence:

1 3/5 doors = 2 liters of paint

1 door = x liters of paint

Cross Multiply

1 3/5 doors × x liters = 2 liters × 1 door

x liters = 2 liters × 1 door/ 1 3/5 doors

x liters = 2 ÷ 1 3/5

x liters = 2 ÷ 8/5

x liters = 2 × 5/8

x liters = 5/4 liters

x liters = 1 1/4 liters of paint

Hence: 1 1/4 liters of paint is needed for 1 door

(1)

Calculate the circumference (C) of the wheel

C = πd (d is the diameter )

   = 3.14 × 8 = 25.12 cm

Now divide the distance travelled by the circumference.

times rotated = 12560 ÷ 25.12 ≈ 500

----------------------------------------------------------------

(2)

The area (A) of a circle is calculated as

A = πr² ( r is the radius )

Find r by using the circumference (C)

2πr = 50.24 ( divide both sides by 2π )

r = 50.24 ÷ 6.28 = 8 , then

A = 3.14 × 8² = 3.14 × 64 ≈ 200.96 ft² ( student 3 )

-----------------------------------------------------------------

C = πd = 3.14 × 30 = 94.2 ≈ 94 m

Answer:

Step-by-step explanation.

The slope is the change in y over the change in x. If you look at the change in y, it goes from 2 to 3, and 3-2=1. If you look at the change in x, it goes from -1 to 3, and 3-(-1)=4 (if you subtract a negative it adds the number instead). IF you put the change in y over the change in x, you get 1/4, which is D

60%20 is 3 is the answer.

The value of fraction will be 1/3.

A fraction is a part of whole number, and a way to split up a number into equal parts. Or, A number which is expressed as a quotient is called fraction. It can be written as the form of p : q, which is equivalent to p / q.

Given that;

The expression is,

''A fraction of 60 is 20.''

Now,

Let the value of fraction = x

So, We can formulate;

⇒ x of 60 = 20

⇒ x × 60 = 20

⇒ x = 20/60

⇒ x = 2/6

⇒ x = 1/3

Thus, The value of fraction = 1/3

Distribution table for the question is attached below :

Answer:

0.533

Step-by-step explanation:

Let :

M = math

D = Drama

Probability that a randomly chosen student takes math or drama ; P(M u D)

Recall:

P(A u B) = p(A) + p(B) - p(A n B)

P(M u D) =  p(M) + p(D) - p(M n D)

Probability = required outcome / Total possible outcomes

From the table :

P(M) = 119 / 302

P(D) = 67 / 302

P(M n D) = 25 / 302

Therefore,

P(M u D) = 119/302 + 67/302 - 25/302

P(M u D) = (119 + 67 - 25) / 302

P(M u D) = 161 / 302

P(M u D) = 0.5331125

P(M u D) = 0.533 ( 3 decimal places)
