Answer:

a. 120/w = l

120/l = w

b. l times w = 120

Step-by-step explanation:

Step-by-step explanation:

120/W=1

120/W= I

I =W is equal to 10

Answer:

12.4 cm

Step-by-step explanation:

Use the sphere volume formula, V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³

Plug in the volume and solve for r, the radius:

V = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³

7961 = [tex]\frac{4}{3}[/tex][tex]\pi[/tex]r³

1900.55 = r³

12.39 = r

So, the radius of the sphere is approximately 12.4 cm

Answer:

the square root of 5=2.2361

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

Explanation:

The sides are in the ratio 4:7:10

This scales up to 4x:7x:10x showing that the sides are 4x, 7x and 10x. The variable x is some positive real number.

Add up the sides and set this equal to the given perimeter 105. Solve for x.

4x+7x+10x = 105

21x = 105

x = 105/21

x = 5

This value is then plugged into each side

The triangle has sides of 20 cm, 35 cm, and 50 cm.

Note how the ratio 20:35:50 reduces to 4:7:10 after dividing all three parts by the GCF 5. Also, we can see that 20+35+50 = 105 to fully confirm our answer.

Answer:

option b is answer answer

Answer:

its B

Step-by-step explanation:

Answer:

7

Step-by-step explanation:

As we can see, the sides of the bigger triangle is twice that or the smaller

Thus, we have it that for similar sides, we simply have to multiply the smaller side length by 2 to give the larger

We have this as:

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

4y + 10 = 5y+ 3

5y-4y = 10-3

y = 7

Answer:

1. 3240

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:

I think the answer is 20!!!!!

Answer:925

Step-by-step explanation

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:

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.

y = mx + c

So the slope is 5

Answer:

4x+7x-9=90

11x-9+9=90+9

11x=99

x =9

measure of CBD=7x-9

=54

Answer:

Step-by-step explanation:

7x-9+4x=90 degree ( being perpendicular)

11x=90+9

x=99/11

x=9

Angle CBD=7x-9

=7*9-9

=63-9

=54 degree

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:

-8

Step-by-step explanation:

I answered this question a few minutes ago. Value was d = -4

So,

{-12+(-4)}/2

= (-12-4)/2

= (-16)/2

= -8

Answer: A. Multiply the input number by 6

9 x 6 = 54

12 x 6 =72

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:

If IN = 5x – 15 and AT = 55, find x.

the answer is x=14

Step-by-step explanation:

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

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!

24-8 (difference) = 16

16/ 2 numbers = 8 is smallest number

8 + 8(difference) = 16 is largest number

The smaller number is 8

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.

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
