Here’s the answer w the explanation. Answer: Lee’s is beating faster.

Nancy’s heart beats were faster. As you can see from the graph, Nancy is currently going at a rate of 1.25 beats per second as opposed to Lee’s 1.2 beats per second. You can figure this out from dividing
Y/x=rate
I can choose any point of the graph which I can divide.
For this case I choose (20,25)
So I divide 25/20 and I will get 1 5/20 rounding to 1 1/4 and then converted to 1.25 beats per second.
Hope that helps!!

A survey of teens showed that teens in brooklyn, ny aged 13-18 spend 16.9 hours per week online. Teens in charlotte, nc spend 13
creativ13 [48]

To work this out we have to do 16.9  hours - 13.2 hours = 3.7 hours so there is a 13.7hour difference and to show it as an addition equation you do 13.2 hours + 3.7hours = 16.9 hours

Question 3 Determine the leg lengths between the two points: (6, -3) and (-2,4).
Shalnov [3]

Answer:

9

Step-by-step explanation:

→You can use the Pythagorean Theorem to solve this, by plugging in the numbers, like so:

\begin{gathered}a^2+b^2=c^2\\x^2+(x-3)^2=(x+3)^2\end{gathered}

a

2

+b

2

=c

2

x

2

+(x−3)

2

=(x+3)

2

x^2+x^2-6x+9=x^2+6x+9x

2

+x

2

−6x+9=x

2

+6x+9

→Subtract x^2-6x+9x

2

−6x+9 from both sides:

x^2 = 12xx

2

=12x

→Subtract 12x from both sides:

x^2 -12x=0x

2

−12x=0

→Factor out x:

x(x-12)=0x(x−12)=0

→Separate, set = to 0, and solve:

\begin{gathered}x = 0\\x -12=0\end{gathered}

x=0

x−12=0

→ Add 12 to both sides: x = 12x=12

→So we have 0 and 12, as our answers. However, we cannot have 0 as a side length, since this would not be possible.

→All we need to do is take 12, and plug it into the equation for the shortest leg.

\begin{gathered}x - 3=?\\12-3=9\end{gathered}

x−3=?

12−3=9

worty [1.4K]

Answer:

100 Candy Bars

Step-by-step explanation:

Hey!

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

Ayden wants to sell a total of $150 worth of candy bars for his school fundraiser. Each candy bar costs $1.50. How many candy bars will he have to sell in order to meet his goal?

--------------------------------------------------------------------------------------------------------------

We can create an algebraic Equation to solve this.

<u>- We know that Each Candy Bar costs $1.50.</u>

<u>-We multiply the Amount of Candy Bars with the price. </u>

<u>-We know the profit should be $150</u>

⇒ 1.50x = 150

-<u>Divide</u> by 1.50 on both sides

⇒ 1.50x/1.50 = 150/1.50

-<u>Simplify</u>

⇒ x = 100

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

Find the measure of each of the angles. Don’t forget to label your answer
user100 [1]

Answer:

a=125^o

b=55^o

c=55^o

d=55^o

e=125^o

f=55^o

Step-by-step explanation:

step 1

Find the value of x

we know that

(2x+25)^o=(x+75)^o ----> by alternate interior angles

solve for x

Group terms

2x-x=75-25

x=50

step 2

Find the measure of angle a

we know that

a=(x+75)^o ----> by vertical angles

substitute the value of x

a=(50+75)=125^o

step 3

Find the measure of angle b

we know that

a+b=180^o ----> by supplementary angles (form a linear pair)

we have

a=125^o

substitute

125^o+b=180^o

b=180^o-125^o=55^o

step 4

Find the measure of angle c

we know that

c=b ----> by vertical angles

we have

b=55^o

therefore

c=55^o

step 5

Find the measure of angle d

we know that

d=b ----> by corresponding angles

we have

b=55^o

therefore

d=55^o

step 6

Find the measure of angle e

we know that

e=a ----> by alternate exterior angles

we have

a=125^o

therefore

e=125^o

step 7

Find the measure of angle f

we know that

f=d ----> by vertical angles

we have

d=55^o

therefore

f=55^o
