Can u guys help me answer these 2 questions

Answer:

63 coins

Step-by-step explanation:

I am going to assume you are asking how many dollar coins are in the bag, I apologize if I am wrong.

So first, set up the problem. The total number is 517.6 and each coin weighs 8.1

So you would divide 517.6 by 8.1 to get 63.9012346 (which has too many decimal points so round)

But rounding up would get the wrong number because it would be too light for the amount of coins said to be in there, but rounding down gives you 63.

So 63 times 8.1 is 510.3 and the total could consider the weight of the bag into the total 517.6.

Answer:

  ∠SPR = 48°

Step-by-step explanation:

The relevant relations are ...

Since PR is a diameter, triangle PQR is a right triangle with angle PQR being the right angle.

This makes ∠PRQ complementary to ∠RPQ:

  ∠PRQ = 90° -28° = 62°

Exterior angle RTS is the sum of interior angles TRQ and TQR, so angle TQR can be found to be ...

  110° = 62° +∠TQR

  ∠TQR = 110° -62° = 48° = ∠SQR

__

Angle TQR, also angle SQR, subtends arc SR, so is the same measure as angle SPR, which also subtends the same arc.

  ∠SPR = 48°

Answer:

n < -2

Step-by-step explanation:

-2n – 2 > 2

-2n (– 2 + 2) > 2 + 2

-2n > 4

-2n/-2 > 4/-2

n < -2

Answer:

x = 8

Step-by-step explanation:

To get x, we will use the pythagoras theorem;

10² = x² + (12/2)²

100 = x² + 6²

100 = x² + 36

100 - 36 = x²

64 = x²

Swap

x² = 64

x =√64

x = 8

Hence the value of x is 8

Answer:

a = 19

If the rate of change is -8, everytime you do up for x you will minus 8. For example, x = 10 so y = 27 ; x=11 so y = 27-8 = 19 ; x = 12 so y = 19-8 = 11.

Therefore, when x is 11; y is 19

Answer:

A. -0.8

Step-by-step explanation:

non of the other answers will work because they are positive.

Answer:

A, y = -0.8

Step-by-step explanation:

To solve this, you have leave the y alone.

Subtract 4.2 from both sides.

y + 4.2 - 4.2 = 3.4 - 4.2

y = 3.4 - 4.2

y = -0.8

Answer:

t = 4.7 days

Step-by-step explanation:

The half life formula is

N = No * e ^ (-kt)

Where No is the initial amount of the substance

N = 45 e ^ (-.1483 t)

We want 1/2 of the substance left

22.5 is half of 45 grams

22.5 = 45 e ^ (-.1483 t)

Divide each side by 45

1/2 = e ^ (-.1483 t)

Take the natural log of each side

ln(1/2) = ln (e ^ (-.1483 t))

ln(1/2) = -.1483t

Divide each side by -.1483

ln(1/2) / -.1483 = t

t=4.67395

Rounding to the nearest tenth

t = 4.7 days

Answer:

Pueden jugar 10 partidas en 25 minutos.

Step-by-step explanation:

Sabemos que el tiempo de una partida es:

t = 2min + 30 seg

Queremos saber cuantas partidas se pueden jugar en un total de 25 minutos.

Esto es simplemente igual a la cantidad de veces que podemos "meter" 2 minutos y 30 segundos en 25 minutos, que está dado por el cociente:

N = (25 min)/(2min + 30 seg)

Pero para resolver esto, primero tenemos que tener todos nuestros valores en las mismas unidades.

Sabiendo que 60 se  = 1 min

entonces:

30 seg = (30/60) min = 0.5 min

Entonces podemos reescribir:

t = 2 min + 30 seg = 2 min  + 0.5 min = 2.5 min

Ahora podemos resolver el cociente:

N = (25 min)/(2.5 min) = 10

Esto significa que pueden jugar 10 partidas en 25 minutos.

Answer:

Step-by-step explanation:

The graph has an initial value (y-intercept) of 6 and a slope of 2/3, using the slope intercept formula, the graph has the equation

y = (2/3)x + 6

Answer:

Step-by-step explanation:

The exponential decay function is

[tex]v(t)=a(b)^t[/tex] where a is the initial value of the car, b is the rate of decay, and t is the time in years. Our rate of decay can also be written as (1 - r) where r is the depreciation in decimal form. Our equation looks like this:

[tex]v(t)=10000(1-.07)^t[/tex] which simplifies to

[tex]v(t)=10000(.93)^t[/tex] Now we can solve our problem for any number of years you'd like. We've been tasked to find the value of the car after 3 years, so:

[tex]v(t)=10000(.93)^3[/tex] which simplifies a bit to:

[tex]v(t)=10000(.804357)[/tex] so

v(t) = 8043.57

2. 324×10^-1

Step-by-step explanation:

1. 32.4×10^<2

32.4×100

3240

Answer:

1.

[tex]32.4 \times {10}^{2} = 32.4 \times 100 = 3240[/tex]

2. when you multiply any number has decimal point by 10 power specific number [10^N]

if N is negative move with decimal point move to left On the contrary if N is positive you must move to right

Ex :

[tex]22.4 \times {10}^{ - 1} = 2.24 \\ \\ [/tex]

[tex]22.4 \times {10}^{} = 224[/tex]

Answer:

The kite is 73.4 feet above the ground.

Step-by-step explanation:

125 sin 34=

Cross multiply.

x=69.899112...

x=69.899112...

{Add 3.5, the distance from the ground to her hand:}

Add 3.5, the distance from the ground to her hand:

69.899112...+3.5=

73.399112...

The kite is 73.4 feet above the ground.

A right angled triangle is a triangle (has three sides and three angles) in which one of the angles measure 90°.

Trigonometric ratios is used to show the relationship between the sides of the right angled triangle and its angles.

Let h represent the perpendicular distance from the top of the kite to her hand. The angle of elevation = 34°. Hence:

sin(34) = h/125

h = 69.9 feet

The distance from the kite to the ground = 69.9 + 3.5 = 73.4 feet

Answer:

The formula is the area of the base times the one third of the height.  You need to find one third of the height.  Then multiply it by 8.  "In terms of pi" just means you leave the pi symbol beside your number instead of actually multiplying it.

The smaller number is 8

Answer:

8*8

Step-by-step explanation:

Hre we can divide the time worked (hrs) by the amount made!

Generally I wouldn't do this for the whole table, but considering its not very big we will!

$16/2hrs =8

$24/3hrs = 8

$40/5hrs = 8

From this we can deduce that every hour, 8 dollars are earned.

The equation would be x=8h

but for this 8dollars * 8 hrs is right!

Answer:

0.05 = 5/100

sqrt(0.05] = sqrt(5/100) = sqrt(5)/sqrt(100) = 2.24/10 = 0.224

0.0005 = 5/10000

sqrt [0.0005) = sqrt(5/10000) = sqrt(5)/sqrt(10000) =

= 2.24/100 = 0.0224

0.5 = 50/100

sqrt(0.5) = sqrt(50/100) = sqrt(50)/sqrt(100) = 7.07/10 =

= 0.707

0.005 = 50/10000

sqrt(0.005) = sqrt(50/10000) = sqrt(50)/sqrt(10000) =

= 7.07/100 = 0.0707

Step-by-step explanation:

it would be nice, if you could truly type the full and real question.

you mean sqrt(50) = 7.07

right ?

this assumption leads to the answers above.
