PLEASE HELP!!!!!!!!!!!!!!!!!

Answer:

Your heart rate is 1.1 beats per second. Your friend's heart rate is 1.2 beats per second. Yes, the rates have the same rate (bps).

Step-by-step explanation:

Your heartbeat = 22:20 (can  be reduced to 11:10) or 22/20 = 1.1 bps

Friend's heartbeat = 18:15 (can be reduced to 6:5) or 18/15= 1.2 bps

55-15=40

40÷10=4

Answer:

Correct option is A

Since it is an equilateral triangle, the lengths of the sides are equal

So, x+3 y=3 x+2 y−2=4 x+

2

1

​

y+1

x+3 y=3 x+2 y−2

y=2 x−2

2 x−y=2 ...(1)

Also, 4 x+

2

1

y+1=x+3 y

8 x+y+2=2 x+6 y

6 x+2=5 y

6 x−5 y=−2   ...(2)

Multiplying e q(1) by  5 we get,

10 x−5 y=10      ...(3)

Subtracting e q(2) from e q(3) we get,

4 x=12⇒x=3

y=2 x−2=4

The length of one side of equilateral triangle = x+3 y =3+3(4)=15 units

Hence, the area of the parallelogram is 143 in².

Answer:

Step-by-step explanation:

The pairs of angles referenced in statements 1 and 2 are "corresponding" angles, so the Corresponding Angle Postulate applies.

The Reflexive Property is what says something is the same as itself. This is used in statement 3.

The upshot of the AA Similarity postulate is to say triangles are similar (as in statement 4).

Answer:

x = 114 , ∠A = 132 , ∠B = 114 and ∠D = 124

Step-by-step explanation:

The polygon has 7 sides

A 7 sided polygon has angles that add up to 900 degrees.

So if we add all the measures of the angles and set it to 900 we can solve for x

900 = x + 18 + 132 + 130 + 130 + x + 10 + 138 + x

step 1 : combine like terms

18+132+130+130+10+138 = 558

x + x + x = 3x

We now have 3x + 558 = 900

step 2 : subtract 558 from both sides

900 - 558 = 342

we then acquire 342 = 3x

step 3 : divide both sides by 3

342 / 3 = 114 and 3x / 3 = x

we're left with x = 114

Now we plug in the value of x into the x's to find the measures of the unknown angles

∠B = x and x = 114 so ∠B simply has a measure of 114°

∠A = x + 18

x = 114

∠A = 114 + 18 = 132°

∠D = x + 10

x = 114

∠D = 114 + 10 = 124°

So we can conclude x = 114 , ∠A = 132 , ∠B = 114 and ∠D = 124

Hence, value of x is 4

The value of x from the expression is 4

Equations are expressions separated by an equal sign

Given the expression

4x = 16

We are to get the value of x

Divide both sides by 4

4x/4 = 16/4

x = 4

Hence the value of x from the expression is 4

Answer:

h = [tex]\frac{T - 2\pi r^{2}}{2\pi r}[/tex]

Step-by-step explanation:

T= 2rπh + 2πr²

Subtract terms that don't include the indicated variable from both sides:

T= 2rπh + 2πr²   ⇒   T - 2πr² = 2rπh

Divide values being multiplied by indicated variable from both sides:

T - 2πr² = 2rπh   ⇒   [tex]\frac{T - 2\pi r^{2}}{2\pi r}[/tex] = h

Answer: x= 55 because 60 + 65 =125 and 180 - 125 = 55

Step-by-step explanation:

The sum of three angles in any triangle is 180. Therefore you add the two angles that you have and use that number to subtract it by 180. Then you will have your answer. Also you can get the answer to y by subtracting the value of x from 180.

-3/12

Step-by-step explanation:

In negative numbers, it's basically the opposite of regular numbers.

Let's explain negative numbers as debts. Let's say you owe a friend 1 dollar, and another 2 dollars. In a sense, you'll have -1 dollars, and -2 dollars. Which one is the greater number? It'll be -1 as you're only losing 1 dollar. Same goes here. Although 1 is a greater number than 3/12, in negative form it isn't.

Answer:

Step-by-step explanation:

No doubt you have examples showing the wording that is expected to be used here. We have made a guess.

power of a ratio: the numerator is raised to the power, as is the denominator. (a/b)^c = (a^c)/(b^c)

power of a product: each factor is raised to the power. (ab)^c = (a^c)(b^c)

power of a power: the powers are multiplied. (a^b)^c = a^(bc)

quotient of powers: the result when one power is divided by another is the difference of the numerator and denominator powers. (a^b)/(a^c) = a^(b-c)

The order of operations tells you to simplify inside parentheses first. Doing that reduces the work somewhat.
