Answer 1

9514 1404 393

Answer:

  B.  18

Step-by-step explanation:

The vertical angles are supplementary to the same angle.

  4x +(2y+x) = 180

  (2y-x) +(2y+x) = 180

We can solve the second equation first to find the value of y:

  4y = 180 . . . . simplified

  2y = 90 . . . . .divide by 2

Substituting into the first equation, we have ...

  5x +2y = 180

  5x +90 = 180

  5x = 90

  x = 18  . . .  matches choice B

The maximum heart rate is the highest heart rate achieved during maximal exercise. In general, you get the most benefits and reduce the risks when you exercise within your target heart rate zone. Usually this is when your exercise heart rate (pulse) is about 80 percent of your maximum heart rate. The formula M = 0.8 ( 220 − A ) M = 0.8 ( 220 - A ) , gives the recommended maximum heart rate, M M , in beats per minute, for a person who is A A years of age. Determine the age of a person whose target heart rate is 128 beats per minute. The recommended maximum heart rate is 128 beats per minute for a person who is years old.

Answers

Answer:

160 years

Step-by-step explanation:

The formula for the heart rate is given by :

M=0.8 (220−A) ...(1)

M is the maximum heart rate in beats per minute and A is the age in years

Put M = 128 beats per minute in the above formula.

128=0.8(220-A)

160=220-A

A=220-160

A = 160 years

So, the age of person is 160 years if heart rate is 128 beats per munute

q(x)= -2x+1
r (x)=x²+2
Find the value of r r(q (2)).

Answers

Answer:

r(q(2)) = 11

Step-by-step explanation:

given r(x) = x^2 + 2, and q(x) = -2x + 1.

Here is the equation to the composite function:

r(q(x)) = (-2x+1)^2 + 2 = 4x^2-4x+3 .

Then just substitute the input and solve:

r(q(2)) = 4(2)^2- 4(2) + 3 = 16 - 8 + 3 = 16 - 5 = 11

______________________________

Or if you don't like this, first find the answer to q(2) = -2(2) + 1 = -3

Then substitute this value into the second equation r(x).

r(x) → r(-3) = (-3)^2 + 2 = 9 + 2 = 11

Describe a transformation that could be used to show that alternate interior angles are congruent.

Answers

Answer:

Step-by-step explanation:

From the picture attached,

Let 'l' be the original line having one angle ∠BAC.

If the original line 'l' is shifted or translated to line 'm', angle BAC will replace the angle BDE.

Since, measure of angles are preserved in the translation,

m∠BDE = m∠BAC [corresponding angles]

Since, ∠BDE ≅ ∠MDA [Vertical angles]

Therefore, m∠MDA = m∠BAC

Hence, alternate interior angles (∠MDA) and (∠BAC) will be congruent when line 'l' is translated to line 'm'.

Kevin was playing a trivia game. For each correct answer he scored 1 1 / 2 points. For each incorrect answer he scored - 1 / 2 point. What was his final score if he got 8 correct and 3 incorrect?

Answers

Answer:

42.5

Step-by-step explanation:

Point for correct score  = [tex]\frac{11}{2}[/tex]  = 5.5

Point for incorrect score = [tex]\frac{1}{2}[/tex] = 0.5

Unknown:

Final score = ?

Solution:

Number of correct score  = 8

   Points gained  = 8 x 5.5 = 44

Number of incorrect score  = 3

  Points lost  = 3 x 0.5  = 1.5

His final score  = 44 - 1.5  = 42.5

Answers

Answer:

Step-by-step explanation:

From the information given;

We are to take a look at a 2⁵ factorial design.

The factorial design consists of carrying out the design of equipment by testing it by modifying not the parameters one by one but by modifying several simultaneous parameters.

An experiment is termed to be a 2⁵ factorial experiment if in the experiment 5 factors are studied consecutively with each at two-level.

Thus, there are five factors and 2 levels in the experiment.

Answer:

L = 20

W = 10

Step-by-step explanation:

L = (w + 10)

NL = (w + 13)

Divide 299 by 13:

299 ÷ 13 = 23

So, 23 x 13 = 299

L = 23

W = 13

Subtract 3 from both to get the original length and width
