Answer:

  MO = 25

Step-by-step explanation:

Point O between parallel lines PQ and MN divides segment PM in the same proportion that it divides segment QN.

  MO/OP = NO/OQ

  MO/20 = 20/16 . . . . . . use the given numbers

  MO = 20(20/16) . . . . . multiply by 20

  MO = 25

Answer:

65 degrees

Step-by-step explanation:

the angles are corresponding, and corresponding angles always have the same angle measures

If a ∥ b and m∠1 = 65°, The measure of m∠2 will be 65°.

When two lines or rays converge at the same point, the measurement between them is called an "Angle." when a transverse line crosses two straight lines, corresponding angles are formed.

When two lines are crossed by a third line, these angles are generated at equivalent corners or corners corresponding to the transversal.

It is given that,  a ∥ b and m∠1 = 65.

If the transversal meets two parallel lines, the corresponding angles theory asserts that the corresponding angles are congruent. In other words, the angles formed when a transversal crosses two parallel lines will always be equal.

Since corresponding angles always have the same angle measures, the angles are said to be corresponding.

As a result,

m∠1 =m∠2

m∠1 = 65°

m∠2=65°

Thus, if a ∥ b and m∠1 = 65°, The measure of m∠2 will be 65°.

i THINK 43% but im not for sure

Step-by-step explanation:

Answer:

equation

Step-by-step explanation:

Inverse operations are used to solve simple algebraic equations to more difficult equations that involve exponents, logarithms, and trigonometry. Mathematically, inverse operations are opposite operations. Addition is the opposite of subtraction; division is the opposite of multiplication, and so on.

[RevyBreeze]

Answer:

equation

Step-by-step explanation:

To isolate the variable, we must reverse the operations acting on the variable. We do this by performing the inverse of each operation on both sides of the equation. Performing the same operation on both sides of an equation does not change the validity of the equation, or the value of the variable that satisfies it.

Answer:

He forgot to multiply by 1/2 when finding the area of the above triangle.

Now we find the correct area;

A = BH x 1/2 (formula for finding area of triangle)

A = 10 x 24 x 1/2

A = 240 x 1/2

A = 240/2

A = 120

Now the rectangle's formula which is just (W x L) where "w" is the width and "l" is the length;

A = W x L

A = 24 x 15

A = 360

Now we add both the sums of the two areas:

120 + 360 = 480 square feet, the information provided here is your explanation.

Given parameters:

   Expression;

                        6¹²

Identify the exponent and the base in the expression;

                         6¹²

An exponent is a power to which a number or variable is raised.

Generally, it signifies the number of times a number should be repeatedly multiplied.

The base is the number that is being multiplied.

So, in this problem, exponent is 12 and base is 6.

Answer:

X = -1/2 or X = 0.50

Step-by-step explanation:

8x - 1 + 4x + 7

    Combine like terms

12x + 6 = 0

     Isolate X

12x + 6 = 0

      - 6 = 0

12x = -6

12x/12 = -6/12

X = -1/2

Answer:

y = 2x + 3

Step-by-step explanation:

to find the perpendicular line then you have to find the negative reciprocal which is 2 and to get that you flip the fraction and change the sign so

(-1/2) → 2/1 or 2

the y-intercept coordinate is (0, 3) so the y-intercept is 3

Slope of the Perpendicular line=2

The number of minutes that she practiced on Tuesday compared to Monday will be 103 minutes.

The analysis of mathematical representations is algebra, and the handling of those symbols is logic.

PEMDAS rule means the Parenthesis, Exponent, Multiplication, Division, Addition, and Subtraction. This rule is used to solve the equation in a proper and correct manner.

Melissa practiced piano for 5/6 of an hour on Monday and 8/9 of an hour on Tuesday.

The number of minutes that she practiced on Tuesday compared to Monday will be

⇒ (5/6) + (8/9)

⇒ 31/18

⇒ 103 minutes

The number of minutes that she practiced on Tuesday compared to Monday will be 103 minutes.

Step-by-step explanation:

Hopefully I didn't misinterpret

Starting bpm = 91

Resting bpm = 72.8

=========================================================

Explanation:

A 30% increase is represented by the multiplier 1.30 because

100% + 30% = 1.00 + 0.30 = 1.30

So Krystal's initial heart rate is 1.30*70 = 91 bpm.

If you wanted, you can think of it like this

30% of 70 = 0.30*70 = 21 is added onto the initial 70 bpm to get 70+21 = 91 bpm.

-----------

To decrease by 20%, we use the multiplier 0.80 since

100% - 20% = 1.00 - 0.20 = 0.80

Losing 20% of something means we keep the remaining 80%

So,

80% of 91 = 0.80*91 = 72.8 bpm.

-----------

Here's one way to find the final bpm in one single line

1.30*0.80*70 = 72.8

in which you could write it like this

(1 + 0.30)*(1 - 0.20)*(70) = 72.8

The second way may be a bit longer, but I find it's more descriptive to see where the percentage increases vs percentage decreases are.
