Answer:

What's the question??

Answer:

Slope for AB is 0

Step-by-step explanation:

Y=b

Y = -2

Y= y-intercept because there is no slope so y=b instead of y=mx+b

Answer:

300L per hour

Step-by-step explanation:

The rate of change of volume of blood pumped by the teenager's heart expresses the volume of blood pumped with respect to hour.

Rate of change of volume of blood = [tex]\frac{volume of blood}{time}[/tex]

                           = [tex]\frac{7200L}{24}[/tex]

                           = 300L/hour

The rate of change of volume of blood by the teenager's heart is 300 litres per hour. This implies that his/ her heart pumps 300 litres of blood every hour.

Answer:

m∠ABC = 68°

m∠DEF = 112°

Step-by-step explanation:

Supplementary angles are angles that add up to 180 degrees (they form a straight line).

If ∠ABC and ∠DEF are supplementary, that means that they add up to 180. We can write this in an equation:

Combine like terms.

Divide both sides by 18.

Find the measure of each angle by substituting 10 for x into both expressions for the angles.

m∠ABC = (6x + 8)°

m∠DEF = (12x - 8)°

→ (6x + 8) + (12x - 8) = 180°

→ 6x + 8 + 12x - 8 = 180°

→ 18x = 180°

→ x = 180 ÷ 18

→ x = 10°

Now, we are given that m∠ABC = (6x+8) just subsitute the value of x in it .

→ m∠ABC = (6x + 8)

→ m∠ABC = (6 × 10 + 8)

→ m∠ABC = 60 + 8

→ m∠ABC = 68°

Similarly, subsitute the value of x in m∠DEF = (12x - 8)° we get :

→ m∠DEF = (12x - 8)°

→ m∠DEF = (12 × 10 - 8)

→ m∠DEF = 120 - 8

→ m∠DEF = 112°

Answer:

∠ 2 = 60°

Step-by-step explanation:

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the given angles fro 180° for ∠ 2, that is

∠ 2 = 180° - (57 + 63)° = 180° - 120° = 60°

Answer:

17:14 or 17 to 14

Step-by-step explanation:

since you know there are 14 girls, subtract 14 from 31 and then you'll get 17. since its asking for a ratio of boys to girls not girls to boys, you put boys first, then girls. so your answer will be 17:14

Answer:

I think it is

1: 22.37

2:16.81

3:83.16

Step-by-step explanation:

Answer:

Shape 1: 22.365

Shape 2: 16.81

Shape 3: 83.16

Step-by-step explanation:

I'm going to start with 2, because its the easiest shape to do, which is 4.1*4.1= 16.81. Next is 3, which you find the length by adding 4.1 to 9.1 = 13.2. You then multiply 13.2 by 6.3 = 83.16. Finally for shape 1, you first find the bottom shape,  which you do by dividing 6.3 by 2 so you can get the width of half the triangle. That is 3.15. then you multiply that by 7.1 to get the area of 22.365.

Step-by-step explanation:

Hit Water:

He hits the water when his height, h(t), is 0 meters above water.

0 =  

This is no factorable so we use the quadratic formula.

(-b±√(b²-4ac))/2a

(-10±√(10²-4*-5*3))/2*-5

(-10±√(100+60))/-10

(-10±√160)/-10

(-10±√16*10)/-10

(-10±4√10)/-10

(-10±4√10)/-10         Seperate to two equations

(-10+ 4√10)/-10                          and                (-10- 4√10)/-10

(-10+12.65)/-10                                                 (-10-12.65)/-10  

-.265 Not Solution                                          2.265 Seconds

Becasue there is no negative time

The diver hits the water at 2.265 seconds

For when he is at the same height as the spring board, we need to find the height of the spring board, and we do that by substituting 0 for t because we need the height 0 seconds after he jumps.

h(0) = -5*0^2 +10*0 +3

h(0) = 3   The height of the spring board is 3 so we need to know when he is at 3 meters again.

3= -5t^2 + 10t + 3       Subtract 3 from both sides

0= -5t^2 +10t

0= -5(t^2-2t)       Factor out -5 and divide both sides by -5

0= t^2-2t    

0= t(t-2)      Factor out t.

Solve.

t= 0               t-2=0

                    t= 2

He will be at the same height as the spring board at t= 2 seconds

Answer:

6/25 or 0.48

Step-by-step explanation:

0.4 / (5/6)=0.48

48/100=24/50

X = 6

because 8 - 2 = 6

Answer:

Step-by-step explanation:

p1(-3,2) p2(2,6)

find the slope of the line between these two points

m= 6-2 /2-(-3)

m=4/5

find the slope of the line between p2 and p3(8,-1)

m=-1-6 /8-2

m=-7 / 6

dist= sqrt( (8-(-3))^2+(-1-2)^2)

dist = 11.40175    (1 to 3)   hyp

dist = sqrt( (8-2)^2 + (-1-6)^2)

dist = 9.219544  (2 to 3)

dist = sqrt( (2-(-3))^2 + (6-2)^2)

dist = 6.403124 ( 1 to 2)

use law of cosines to find an angle

law of cosines cos(C) = (a^2+b^2-c^2) / (2ab) =97.61°

cos(A) = (b^2+c^2-a^2) / ( 2bc) = 32.23°

cos(B) = (a^2+c^2-b^2) / (2ac) =50.16°

do the same process as above but for the points in 23

This took me a few hours  :/   granted  I took a break for dinner but still .. pay me for that much work  :D..     if you can't get  23 later re post question I'll work on it later

Answer:

12

Step-by-step explanation:

8x-1+3x+4+3x+9=180

14x+12=180

14x=180-12

x=168/14

x=12

Answer:

8x-1+3x+9+3x+4=180

8x+3x+3x=180+1-9-4

14x=168

x=12

Step-by-step explanation:

Answer:

17.75x + 5.25 [tex]\leq[/tex] 165

x [tex]\leq[/tex] 9

Step-by-step explanation:

The total cost can be represented by 17.75x + 5.25, where x is the number of people.

They can only spend a maximum of $165, so a less than or equal sign has to be used.

The inequality will be 17.75x + 5.25 [tex]\leq[/tex] 165

Now, solve for x:

17.75x + 5.25 [tex]\leq[/tex] 165

17.75x [tex]\leq[/tex] 159.75

x [tex]\leq[/tex] 9

So, x [tex]\leq[/tex] 9 is the answer, meaning 9 people or less can go to the amusement park.

Answer:

[tex]y = \frac{5}{8} + x[/tex]

Step-by-step explanation:

Given

[tex]Kiran = x[/tex]

[tex]Andre = y[/tex]

[tex]Andre = \frac{5}{8}\ minutes\ more[/tex]

Required

Write an equation that represents the scenario

[tex]Andre = \frac{5}{8}\ minutes\ more[/tex] means that Andre read 5/8 minutes more than Kiran and this can be represented as:

[tex]Andre = \frac{5}{8} + Kiran[/tex]

Substitute x for Kiran

[tex]Andre = \frac{5}{8} + x[/tex]

Substitute y for Andre

[tex]y = \frac{5}{8} + x[/tex]

Answer:

Answer:

x = 1.8

Step-by-step explanation:

Given

2.5(10x - 16) = 5 ( divide both sides by 2.5 )

10x - 16 = 2 ( add 16 to both sides )

10x = 18 ( divide both sides by 10 )

x = 1.8

Answer:

333×2+999-999÷2= 333

Step-by-step explanation:

Answer:

333

Step-by-step explanation:

333 x 2 = 666

666 divided by 2 = 333

999 - 999 = 0, so it doesn't do anything to the final number

The answer is 333
