Answer:

33

Step-by-step explanation:

Answer:

5

Step-by-step explanation:

AC=√(3^2+4^2)=√(9+16)=√(25)=5

Step-by-step explanation:

step 1. the diagram is very unclear and should be redone

step 2. I'll assume 9r - 17 and 3r + 13 are vertical angles and are equal

step 3. 9r - 17 = 3r + 13

step 4. 6r = 30 or r = 5

step 5. I'll assume 4s - 3 and 7s - 24 are alternate interior angles and are equal

step 6. 4s - 3 = 7s - 24

step 7. 3s = 21 or s = 7.

Answer:

10.9

Step-by-step explanation:

Your gonna use the Pythagorean theorem to find x

5^2+x^2=12^2

x^2= 12^2- 5^2

x^2= 144-25

x^2= 119

x= root 119 or 10.9

Answer:

x = -37.5

Step-by-step explanation:

Set up a proportion so -5/12.5 = 15/x

Solve for x so -5x = 15(12.5) so -5x = 187.5 so x = -37.5

y=-2/3x+4

Step-by-step explanation:

i found the slope using rise and run equation, its -2/3

i just saw that the y-intercept is -4, and yeah.

Answer:

  a) $2.40

  b) $16.80

  c) y = -2.40x +16.80

Step-by-step explanation:

a. Dylan's daily spending is the opposite of the slope of the line on the graph. That slope can be found using the slope formula:

  m = (y2 -y1)/(x2 -x1)

  m = (4.8 -12)/(5 -2) = -7.2/3 = -2.4

Dylan spends $2.40 at lunch every day.

__

b. The y-intercept can be found from the formula ...

  b = y1 -m(x1)

  b = 12 -(-2.40)(2) = 16.80

Dylan's dad gives him $16.80 at the beginning of each week.

__

c. The slope-intercept equation is ...

  y = mx + b

  y = -2.40x +16.80

Answer:

7 is B

8 is C

9 is D

Step-by-step explanation:

Hey There!

So as you can see in the first image the slope of a line that passes through the coordinates (-3,1) and (5,-7) is -1

As you can see in the second image the equation of the line that passes through the points (-2,5) and (3,15) is y=2x+9

The last one is D because the equation is a=2b-3

The statement that says a is equal to 3 LESS then TWICE B is correct cause its saying that 2b - 3 is equal to a

Answer:

After about 9 minutes.

Step-by-step explanation:

We can write an exponential function to model the decay of Herodium-100.

We are given that it decreases by half every minute.

The standard exponential function is given by:

[tex]f(m)=A(r)^m[/tex]

Where A is the initial amount, r is the rate, and m is the rate (in this case, in minutes).

Mathman initially has 2000 mL of Herodium-100. Therefore, A = 2000.

And since it decreases by half every minute, r = 1/2. Thus:

[tex]\displaystyle f(m)=2000\Big(\frac{1}{2}\Big)^m[/tex]

Mathman needs to rest when the Herodium-100 levels drop to 4 mL. Therefore, we can substitute 4 for f(m) and solve for m:

[tex]\displaystyle 4=2000\Big(\frac{1}{2}\Big)^m[/tex]

Solve for m. Divide both sides by 2000:

[tex]\displaystyle \frac{4}{2000}=\frac{1}{500}=\Big(\frac{1}{2}\Big)^m[/tex]

We can take the natural log of both sides:

[tex]\displaystyle \ln\Big(\frac{1}{500}\Big)=\ln\Big(\frac{1}{2}^m\Big)[/tex]

By logarithm properties:

[tex]\displaystyle \ln\Big(\frac{1}{500}\Big)=m\ln\Big(\frac{1}{2}\Big)[/tex]

Therefore:

[tex]\displaystyle m=\frac{\ln(1/500)}{\ln(1/2)}\approx 8.9657\approx 9\text{ minutes}[/tex]

Mathman will have to rest and replenish after 9 minutes.

Answer:

3 points = 6

2 points = 32

Step-by-step explanation:

Points scored = 82

Let

Number of 2 points goals = x

Number of 3 point goals = y

2x + 3y = 82 - - (1)

x = 5y + 2 - - - (2)

(1) Becomes :

2(5y + 2) + 3y = 82

10y + 4 + 3y = 82

13y = 82 - 4

13y = 78

y = 78/13

y = 6

x = 5y + 2

x = 5(6) + 2

x = 30 + 2

x = 32

Answer:

140x^2−384x+37

Step-by-step explanation:

(10x+−1)(14x+−37)

=(10x)(14x)+(10x)(−37)+(−1)(14x)+(−1)(−37)

=140x^2−370x−14x+37

Answer:

X=9

Step-by-step explanation:

Pull out like factors :

  -4x + 36  =   -4 • (x - 9)

 Solve :    -4   =  0

This equation has no solution.

A a non-zero constant never equals zero.

 Solve  :    x-9 = 0

Add  9  to both sides of the equation :

                     x = 9

Answer:

Total number of balloons= 160

Step-by-step explanation:

Giving the following information:

Number of balloons inflated by Zoey= 24

Proportion of balloons inflated= 15%

To calculate the total number of balloons, we need to use the following formula:

Total number of balloons = Number of balloons inflated by Zoey / Proportion of ballons inflated

Total number of balloons= 24 / 0.15

Total number of balloons= 160

Answer:

fast multiply 5 by 39 to get the total age of the five people now as you are told those per 5 so imagine the six person being you if you enter you're going to add to their ages so they mean is going to be for six people so take the six people x their mean age now we have two different total ages for the five people and for the six people subtract the total age of the 5 from the 6th total ages to get the age of the person who entered the room if you don't understand please ask me and be willing to help

Answer:

The age of the person who entered the room is 21.

Step-by-step explanation:

Mean of 5 peoples = 39

i.e.

Sum / 5 = 39

Sum = 39 x 5

Sum = 195

Mean after one person enters the room = 36

Let x be the age of the new person.

Then

Mean = (Sum + x)/ 6

36 = (195 + x)/6

36 x 6 = 195 + x

216 = 195 + x

x = 216 - 195

x = 21
