John can cover 2 miles in 1 minute

Step-by-step explanation:

There are 180 minutes in 3 hours. So 360 ÷ 180 = 2

Enjoy your day! ( ･U･)♡

Step-by-step explanation:

no it does not form a right triangle. 

a+b+c = 250

1002 + 502 does not equal 1002

nor 1002 + 1002  does not equal 502

so therefore the sides are 100, 100, and 50 but these do not make a right triangle

Answer:

your so funny for a annoying kid

Step-by-step explanation:

A convenience store purchased a magazine and marked it up 100% from the original cost of $2.30. A week later, the store placed the magazine on sale for 50% off. What was the discount price?

The reciprocal of a whole number is a fraction with the whole number as the denominator.

Set up the equation:

10 * 1/x = 5 * 1/3

Simplify:

10/x = 5/3

Multiply both sides by 3:

30/x = 5

multiply both sides by x:

30 = 5x

Divide both sides by 5:

x = 6

Answer: 6

Answer:

Step-by-step explanation:

4x² + 20x + 25 = (2x)² + 2* 2x *5 + 5²

{Compare with a² + 2ab + b² = (a+ b)²}

                         = (2x + 5)²

                         = (2x +5)*(2x+5)

Side of the square = 2x+ 5

Answer:

Part A is (2x+5)^2. Part B is  (2x+3y)(2x-3y).

Step-by-step explanation:

Part A: The polynomial is prime. When you split the middle term, it becomes 4x^2+10x+10x+25. Then rewrite using the common factor from the two pairs. 2x(2x+5)+5(2x+5). Rewrite in factored form, which is (2x+5)(2x+5). Then combine which is, (2x+5)^2. The length of each side is (2x+5)^2.

Part B: The polynomial is prime. Rewrite 4x^2 as (2x)^2 and 9y^2 as (3y)^2, which looks like (2x)^2-(3y)^2. Both terms are perfect squares. The answer is (2x+3y)(2x-3y).

Answer: Multiple answers

Step-by-step explanation:

P.E.M.D.A.S (order of operations)

Parentheses, Exponents, Multiplication and Division, Addition and Subtraction (From left to right)

M=Multiplication

D=Division

Multiplication is done before division.

So, multiply 1.21*2 for the first problem, and 1.20*2 for the other 2 problems.

1.

24/(1.21)2 becomes 24/2.42

24/2.42= 9.9173553719 (or 9.92 rounded, or 9.9)

2.

29/(1.20)2 becomes 29/2.4

29/2.4= 12.0833333333 (or 12.08 rounded, or 12.1)

3.

40/(1.20)2 becomes 40/2.4

40/2.4= 16.6666666667 (or 16.7 rounded)

I am not sure if you have to round your answers up, so I provided those answers as well in case.

Hope this helps!

Answer:

23:18,23 to 18,23/18

Step-by-step explanation:

the three ways to write a ratio are colon,the word to, and the divide symbol .

The triangle that does not have the y angle, equate all of its angles to 180 degrees and solve for x. Once you solve for x, substitute that value to the angles in the other triangle, and then add them all up and equate it to 180 degrees to solve for y.

Answer:

Step-by-step explanation:

So the sum of 128 and x+10 is on a straight line which is 180º right?, so:

x + 10 + 128 = 180

x = 180 - 128 - 10

x = 42º

Answer:

42

Step-by-step explanation:

x +10 +128 = 180   {Linear pair}

x  + 138 = 180

x = 180 - 138

x = 42

Answer:

2400 eggs

Step-by-step explanation:

1. To find out how many eggs the poultry farmer had originally, we have to reverse the steps of him selling and eating this eggs.

2. (Solving)

Therefore, he had 2400 eggs originally.

Answer:

A  8º

B  76º

C  74º

D  128º

Step-by-step explanation:

The sum of the angles is 360

(3x + 10) + (3x + 4) + (x + 50) + (5x + 8) = 360

Combine like terms

12x + 72 = 360

Subtract 72 from both sides

12x = 288

Divide both sides by 12

x = 24

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

A (3x+10) = 3*24 + 10 = 82

B (3x+4) = 3*24 + 4 = 76

C (x+50) =  24 + 50 = 74

D (5x+8) = 5*24 + 8 = 128

devide both sides on 3 and x=6

as u can see 3*6=18

u have to find a number hat when its multiplied on 3 equals 18

so x(the number were searching for) is 6

Answer:

x = 6

Step-by-step explanation:

1. Divide Both Sides By The Coefficient

18/3 = 3x/3

6 = x

2. Move the variable to the Left

x = 6

Answer:

4 days

Step-by-step explanation:

June starts on Monday

for 30days we have 4 weeks starting from Monday to Sunday and extra 2 days which are Monday and Tuesday

so we have 5 mondays and tuesdays

4 wed, thu, fri, sat, sun

Aliza played piano on june1 monday

So aliza played basketball on 5 tues + 4 thurs = 9 days

for calculating both basketball and paino

piano day should be on tuesday or thursday

from the below picture u can see pink dots are piano days

and yellow circles are both piano and basketball days

so on alternate weeks they are coinciding

so there are 4 days

Answer:

Step-by-step explanation:

-3-5=-8

-11-(-3)=-11+3=-8

-19-(-11)=-19+11=-8

it is an A.P. and c.d.=-8

so nth term is

an=a1+(n-1)d

an=5-(n-1)(-8)

an=5+8n-8

an=8n-3

Answer: 2.4

Step-by-step explanation:

Because they are similar, the lengths of the sides will have the same ratio.

We will use side AB and side XY since it shows both sides.

This shows that the ratio is 3:4

We can then use that to find out that XZ also uses the ratio 3:4

3.2 / 4 = 0.8

0.8 * 3 = 2.4

XY is equal to 2.4

Answer:

If you're trying to find h, then the answer is A.

Step-by-step explanation:

5.3 x 2.98 = 15.79, which rounds up to 15.8.

15.8 + 3 = 18.8

Answer:

A. 2.98

Step-by-step explanation:

When you substitute h for the answers shown, you get different numbers.

When you substitute h for 2.98 you are given 15.794

15.794 + 3 is 18.794

Rounding 18.794 to the next tenth is 18.8

Answer: A. 2.98
