Solve the equation y-12=4y

andre [41]

Hi there!

$y - 12=4y 

We need to subtract 4y from both sides 

y-12-4y = 4y - 4y 

3y - 12=0 

3y = 0 + 12 

3y=12 

Divide both sides by 3 

-3y/3 = 12/-3 

y= -4$

Can y’all help me? Thanks :)

Answer:

Step-by-step explanation:

Soooo, by looking at the picture we can tell that it is a right trapezoid

The formula for the area is

(b1+b2)/2*h

(Base 1+ Base 2)/ 2 * height

Now we can plug in the numbers:

(5+15)/2*6

20/2*6

10*6

=60

1 gallon of paint per sq. foot

So Isha needs 60 gallons of paint

The weights of certain machine components are normally distributed with a mean of 8.04 g and a standard deviation of 0.08 g. Fin

NISA [10]

Answer:

The bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.

Step-by-step explanation:

We are given that

Mean, $\mu=8.04 g$

Standard deviation, $\sigma=0.08g$

We have to find the two weights that separate the top 3% and the bottom 3%.

Let x be the weight of machine components

$P(Xx_2)=0.03$

$P(X$

=0.03

From z- table we get

$P(Z1.88)=0.03$

Therefore, we get

$\frac{x_1-8.04}{0.08}=-1.88$

$x_1-8.04=-1.88\times 0.08$

$x_1=-1.88\times 0.08+8.04$

$x_1=7.8896$

$\frac{x_2-8.04}{0.08}=1.88$

$x_2=1.88\times 0.08+8.04$

$x_2=8.1904$

Hence, the bottom 3 is separated by weight 7.8896 g and the top 3 is separated by weight 8.1904 g.

Hello!

2.
To find the area of a kite we use the equation $\frac{pq}{2}$

p is the line in the kite that goes from top to bottom
q is the line in the kite that goes from left to right

put in the values

$\frac{10 * 11}{2}$

Multiply

$\frac{110}{2}$

Divide

55

The answer is 55
------------------------------------------------------------------------------------------------------
4.

I believe the answer is 770 yds squared
------------------------------------------------------------------------------------------------------
6.

The ratio is 12:7
------------------------------------------------------------------------------------------------------
8.

I do not know how to do 8 sorry
------------------------------------------------------------------------------------------------------
10.
I can't see the whole picture put I will do my best

Since the angle inside the circle is 50° the side is also 50°
------------------------------------------------------------------------------------------------------
12.
I do not know how to do 12 sorry

Hope this helps!
