What is the answer to this problem and why 60+60×0+1=

Answers

Answer 1
Answer: The answer is 61 because 60+60=120*0=0=1=61
Answer 2
Answer: 60 + 60 x 0 + 1 = 61

Let's go into the, "why" part!

Try to remember this mnemonic:
PEMDAS

Parenthesis
Exponent
Multiplication
Division
Addition
Subtraction

This is what is called the ORDER of OPERATIONS!

Normally you go straight down the list, but...
Keep in mind that Multiplication and Division are on the same priority. Same with Addition and Subtraction.

So first we look to see if there is any numbers in parenthesis. There is not. Any exponents? Nope!
How about Multiplication or Division?
Yep!!!!! Bingo!

60 + 60 x 0 + 1= ?

Do the multiplication first. 60 x 0 = 0 (Because anything times 0 equals 0)

Addition and subtraction come next!

60 and 0 are out so we are left with!

60 + 1 = ?

61!

ΔABC is a right triangle and ∠B is a right angle. If sin ∠A = 3/5, then what is the ratio for tan ∠C?

Answers

Answer:

Tan \ \angle C=(3)/(4)

Step-by-step explanation:

-The sine of an angle in a right triangle is given as:

Sin \ \theta=(Opposite)/(Hypotenuse)\n\n\therefore Sin \ \angle A=(3)/(5)

-From this Trigonometric ratio, we calculate the length of the adjacent as:

b^2+h^2=H^2\n\nb^2=5^2-3^2\n\nb^=4\n\n\therefore Adjacent=4

We then calculate tan ∠C

Tan \ \ theta=(Opposite)/(Adjacent)\n\nTan  \ \angle C=(3)/(4)

Answer:

4/3

Step-by-step explanation:

The right triangle is a 3-4-5 triangle- the opposite side of a is 3 (based on 3/5 which is opp/hyp) and the hypnotuse is 5. The ohter side is 4 no matter how it is solved individually. For tan, it is opp/adj so the opp of angle c is 4 and the adj is 3. Therefore it is 4/3. :D The other person flipped it.

A flower bed is in the shape of a triangle with one side twice the length of the shortest side and the third side is 12 feet more than the length of the shortest side.Find the dimensions if the perimeter is 136 feet​

Answers

x - the shortest side

2x

x + 28

The sum of these must be equal to the perimeter of the flower bed, so

x + 2x + x + 28 = 184

4 x + 28 = 184  Combined like terms

4x = 156  Subtracted 28 from both sides

x = 39  Divided both sides by 4.

So the dimensions are 39 feet, 78 feet, and 67 feet

A rectangle is shown. The length of the rectangle is labeled as 8 cm, and the width is labeled as 6 cm. What will be the perimeter and the area of the rectangle below if it is enlarged using a scale factor of 4.5? (5 points)Perimeter = 46 cm, area = 131.25 cm2
Perimeter = 126 cm, area = 972 cm2
Perimeter = 46 cm, area = 972 cm2
Perimeter = 126 cm, area = 131.25 cm2
Perimeter = 46 cm, area = 131.25 cm2
Perimeter = 126 cm, area = 972 cm2
Perimeter = 46 cm, area = 972 cm2
Perimeter = 126 cm, area = 131.25 cm2

Answers

Answer:

Perimeter = 126 cm, area = 972 cm2

Step-by-step explanation:

Rectangle perimeter:

  • P = 2(w + l)

Rectangle area:

  • A = wl

When scaled, the perimeter will change by same factor but the area by the square of same factor.

Applying to the given rectangle

Perimeter:

  • P = 2(6 + 8)(4.5) = 126 cm

Area:

  • A = 6*8*4.5² = 972 cm²

Correct choice is B

Answer:

Perimeter = 126cm

Area = 972cm^2

Step-by-step explanation:

6*4.5 = 27

8*4.5 = 36

Perimeter = 27*2+36*2= 126 cm

Area = 27*36 = 972 cm^2

What is the solution to the linear equation?
2.8y + 6 + 0.2y = 5y – 14

Answers

Answer:

y = 10

Step-by-step explanation:

Simplifying

2.8y + 6 + 0.2y = 5y + -14

Reorder the terms:

6 + 2.8y + 0.2y = 5y + -14

Combine like terms: 2.8y + 0.2y = 3y

6 + 3y = 5y + -14

Reorder the terms:

6 + 3y = -14 + 5y

Solving

6 + 3y = -14 + 5y

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.

Add '-5y' to each side of the equation.

6 + 3y + -5y = -14 + 5y + -5y

Combine like terms: 3y + -5y = -2y

6 + -2y = -14 + 5y + -5y

Combine like terms: 5y + -5y = 0

6 + -2y = -14 + 0

6 + -2y = -14

Add '-6' to each side of the equation.

6 + -6 + -2y = -14 + -6

Combine like terms: 6 + -6 = 0

0 + -2y = -14 + -6

-2y = -14 + -6

Combine like terms: -14 + -6 = -20

-2y = -20

Divide each side by '-2'.

y = 10

Simplifying

y = 10

Answer:

y= 11

Step-by-step explanation:

we have:

2.8y + 6 + 0.2y = 5y – 14

or 3y + 6 = 5y -14

and 3y + 6 - 6 = 5y -16 -6

and 3y = 5y -22

and 3y - 5y = -5y +5y -22

so -2y = -22

finally y = -22/-2

or y=11

Hope that useful for you.
