Answer: It will take 1 second for the ball to reach a height of 5 meters.

Step-by-step explanation:

Given: The function [tex]h=10t-5t^2[/tex] can be used to find the height(h) of the ball in meters after t seconds.

Now, put h= 5 meters, we get

[tex]5=10t-5t^2[/tex]

[tex]\Rightarrow\ 1=2t-t^2\ \ \[\text{divide both sides by 5}]\\\\\Rightarrow\ t^2-2t+1=0\\\\\Rightarrow(t-1)^2=0\\\\\Rightarrow (t-1)=0\\\\\Rightarrow t=1[/tex]

Hence, it will take 1 second for the ball to reach a height of 5 meters.

Answer:

- 12x + 24

Step-by-step explanation:

Since the perimeter is 2(length) + 2(width) your equation would start out as:

2[-2(3x-1)] + 2(10x)

2[-2(3x-1)] + 20 = 2(-6x + 2) + 20

2(-6x + 2) + 20 = - 12x + 24

Answer:

Decrease or decline in water level per day

Step-by-step explanation:

Given the question above ;

The situation which could be repress Ted by a negative number is the decrease in the water level of the pool being measured :

It could be expressed as - 1 1/2 inches per day

Fall, decrease, loss or reductions are usually modeled in mathematics using the negative sign as it portrays a negative adjustment or reduction in the original amount of a commodity, item or phenomenon.

Furthermore, total decline after 5 days will be ;

-1 1/2 * 5 = (-3/2 * 5) = - 15/2 = - 7.5 inches

The answer is C.

Step-by-step explanation:

The truck can hold up to 22 boxes.

Answer:C

Step-by-step explanation:

Answer:

Yes

Step-by-step explanation:

To determine whether a relation is a function or not, we can do a vertical line test. First, get something like a ruler, put it vertical, then scan it on the relation. If the ruler hits one point of the line, then it is a function. If the ruler hits two points at once, then it is not a function. This passes the vertical line test, because when the ruler hits the relation it only hits one point at a time, making it a function. I hope this helps, I hope it's not wrong but I don't think it is.

Answer:

The shoreline is reduced by 0.5 foot every 10 years

y = -6

The line is horizontal, meaning it is zero slope, and the line is located on -6, making the equation y = -6

Answer:

25 jefes

100 oficiales

175 suboficiales

Step-by-step explanation:

Se nos dice que hay 600 soldados que está representado por una fracción de 600

Podemos obtener el número total de personas en el cuartel.

Representemos el número total de personas en el cuartel como: B

2/3 × B = 600

2B / 3 = 600

Cruz multiplicar

2B = 600 × 3

B = 1800/2

B = 900

Por lo tanto, el número total de personas en el Cuartel es de 900 personas.

De la pregunta se nos dice que:

el resto son oficiales, suboficiales y jefes.

Calcule el número total de personas en el cuartel con 1

El resto se representa como:

1 - 2/3 = 1/3

El número de jefes es 1/12 del resto

Por lo tanto,

= 1/12 de 1/3

= 1/12 × 1/3

= 1/36

El número total de personas = 900

Por tanto, el número de jefes = 1/36 × 900

= 25 jefes

Tenemos 25 jefes

El número de oficiales es cuatro veces mayor que el número de jefes.

= Número de oficiales = 4 (1/36)

= 4/36

= 1/9

El número total de personas = 900

Por lo tanto, el número de oficiales = 1/9 × 900

= 100 oficiales

Tenemos 100 oficiales

El número de suboficiales se calcula como:

900 - (600 + 25 + 100)

= 900 - 725

= 175

Answer:

c) 50

Step-by-step explanation:

Exterior angles equal the sum of opposite interior angles.

Answer:

z=6

Step-by-step explanation:

2(2z−3)=18

Divide each term by 2 and simplify.

2z−3=9

Move all terms not containing z to the right side of the equation.

2z=12

Divide each term by 2 and simplify.

z=6

Hope this helps! :) Plz mark as brainliest!

Answer:

z =6

Step-by-step explanation:

so we simplify from both side.

2( 2z - 3)  = 18

   *2      *2

4z - 6  = 18

     + 6   +6

 4z  = 24

then we divide both sides from 4

4z / 4  =  24/ 4

z = 6

The teacher will give 162 note cards to the fifth student.

Students                       =  1    2    3    4    5
Number of handing     =   2   6   18   54   ?
out note cards

It is pattern of series, its ratio with preceding values remains equal.

Here,
First term(a) = 2
common ratio(r) = 3
Nth term = ar^(n-1)

5th term =  2 x 3^(5-1)
               =  2 x 3^4
               = 162

Thus, the teacher will give 162 note cards to the fifth student.

Answer:

Step-by-step explanation:

21) 64=8(r+2)

Step 1: Simplify both sides of the equation.

64=8(r+2)

64=(8)(r)+(8)(2)(Distribute)

64=8r+16

Step 2: Flip the equation.

8r+16=64

Step 3: Subtract 16 from both sides.

8r+16−16=64−16

8r=48

Step 4: Divide both sides by 8.

8r

8

=

48

8

r=6

29) Step 1: Simplify both sides of the equation.

−4(r+6)=−63

(−4)(r)+(−4)(6)=−63(Distribute)

−4r+−24=−63

−4r−24=−63

Step 2: Add 24 to both sides.

−4r−24+24=−63+24

−4r=−39

Step 3: Divide both sides by -4.

and you get r= 39\4

hope that helps

Answer:  r = 6

Step-by-step explanation:

64= 8(r+2)

64/8  = 8(r+2) / 8  divide both sides by 8

    8 = r + 2       The eights cancel out

- r = 2 + 8         Move the variable to the left and change its sign

- r = - 6             to get id of the negative -r make  the 6 a positive

 r=6

-4(r + 6) = -63

- 4r - 24 = -63    Distribute 4 through ( ) -4 x4  -4 x6

-4r =63 + 24      Move -24 to the right (making it a positive )

-4r = 39

-4r / -4 = 39 /4  divide both sides by -4

r= 39/4

Answer:

44 minutes

Step-by-step explanation:

With regards to the above information, we can calculate the minutes in which Martina's call lasted as shown below;

We can make y represent the minutes

15 - 8y/100 = 11.48

15 - 0.08y = 11.48

15 - 11.48 = 0.08y

0.08y = 3.52

y = 3.52/0.08

y = 44

It therefore means that Martina's call lasted for 44 minutes.

If Talia makes 2 mistakes every 3 minutes then the ratio is 2:3

Going along with that if you know how ratios work then that should be easy. But this is also the long way. You dont really need to know ratios you just need to know the steps but knowing ratios would be helpful.

You first divide

18 / 3  =  6

Then multiply
