Answers

Answer:

The two will retain its unit place value

Step-by-step explanation:

We are given the number 506,092

Which is stated in words as

"Five hundred and six thousand and ninety two"

2 represents 2 units in the number

When we shift 2 by two places to the right, the number becomes

50,609,002

We can still see that "two" still retains it unit place value and the whole number now reads fifty million six hundred and nine thousand and 2

m∠ABC=(6x+8)° and m∠DEF=(12x-8)°.
If ∠ABC and ∠DEF are supplementary,what
is the measure of each angle?

Answers

Answer:

m∠ABC = 68°

m∠DEF = 112°

Step-by-step explanation:

Supplementary angles are angles that add up to 180 degrees (they form a straight line).

If ∠ABC and ∠DEF are supplementary, that means that they add up to 180. We can write this in an equation:

(6x + 8) + (12x - 8) = 180

Combine like terms.

18x = 180

Divide both sides by 18.

x = 10

Find the measure of each angle by substituting 10 for x into both expressions for the angles.

m∠ABC = (6x + 8)°

6(10) + 8 = 68°

m∠DEF = (12x - 8)°

12(10) - 8 = 112°
Answer :

→ (6x + 8) + (12x - 8) = 180°

→ 6x + 8 + 12x - 8 = 180°

→ 18x = 180°

→ x = 180 ÷ 18

→ x = 10°

Now, we are given that m∠ABC = (6x+8) just subsitute the value of x in it .

→ m∠ABC = (6x + 8)

→ m∠ABC = (6 × 10 + 8)

→ m∠ABC = 60 + 8

→ m∠ABC = 68°

Similarly, subsitute the value of x in m∠DEF = (12x - 8)° we get :

→ m∠DEF = (12x - 8)°

→ m∠DEF = (12 × 10 - 8)

→ m∠DEF = 120 - 8

→ m∠DEF = 112°

At her restaurant .Yolanda open 285 cans of tomato sauce .She need to use 4 can of for one pan of lasagna how many pans of lasagna could yolanda make if she uses all if she all the cans what is the answer in a mixed numder

Answers

Answer:

71 1/4 pans of lasagna

Step-by-step explanation:

4 cans of tomato sauce = 1 pan of lasagna

285 cans of tomato sauce = x pan of lasagna

4 = 1

285 = x

Cross product

4*x = 285*1

4x = 285

x = 285/4

x = 71 1/4 pans of lasagna

Hari's weekly allowance varies depending on the number of chores he does. He received $22 in allowance the week he did 16 chores, and $16 in allowance the week he did 4 chores. Write an equation for his allowance in slope-intercept form.

Answers

9514 1404 393

Answer:

  y = 0.5x +14

Step-by-step explanation:

If we let x and y represent the number of chores and Hari's allowance, respectively, then we have the two points (16, 22) and (4, 16). We can use the 2-point form of the equation for a line to find the equation.

  y = (y2 -y1)/(x2 -x1)(x -x1) +y1

  y = (16 -22)/(4 -16)(x -16) +22 . . . . substitute

  y = -6/-12(x -16) +22 . . . . simplify

  y = 1/2x -8 +22 . . . . eliminate parentheses

  y = 0.50x +14

What is 365 divide by 3

Answers

Answer:

121.666667

Step-by-step explanation:

When 365 is divided by 3 the result or quotient is 121.66.

To calculate 365 divided by 3, we can perform long division:

Set up the division problem.

Determine how many times 3 can fit into the first digit of the dividend (3). The answer is 1.

Bring down the next digit (6) to the right of 3.

Determine how many times 3 can fit into the new number (36). The answer is 12.

Now, bring down the next digit (5) to the right of 12.

Determine how many times 3 can fit into the new number (53). The answer is 17.

Since there are no more digits to bring down, the division is complete.

The final result is: 365 ÷ 3

= 121.666...

Hence, 365 is divided by 3 to get 121.66.

Step-by-step explanation:

plzz follow me

(-4,0) is the solution of the set to the system of inequalities

What is Inequality?

a relationship between two expressions or values that are not equal to each other is called 'inequality.

The given two inequalities are

y<-3x-6 and 4x-2y<-8

Let us check for (-4, 0)

0<-3(-4)-6

0<6

4x-2y<-8

4(-4)-2(0)<-8

-16<-8

So (-4, 0) is the solution of the inequalities.

Now let us check for (0, 2)

replace y value as 2 and x as 0.

2<-3(0)-6

2<-6

Which is not true.

Hence, (-4,0) is the solution of the set to the system of inequalities.

What is the exact question? It seems like you are asking for the Pythagorean theorem. Ok, I’ll try to help if that’s the case.

a^2 + b^2 = c^2
4^2 + 5^2 = c^2
16 + 25 = c^2
41 =c^2
6.403124237432849 = c

So now since we have the answer, we need to figure out if this result and 6 are equal.

6^2 = 36

25 + 16 = 41

41 and 36 are not equivalent so if the case is that u want me to find the Pythagorean theorem, then the answer is that they aren’t equal. And the real answer is that c equals 6.403124237432849. Which means that 4in, 5in, 6in is not the correct order. And that 16in, 25, 41 is the correct order.
