what negative number is the same distance from 0 as the number +4

Answer:

9 1/7

Take 5 4/7 + 3 13/21 and get 9 1/7

x - 3y = -11
-x + 2y = 7

We minus these equations : x - 3y - (-x + 2y) = -18

= x - 3y + x - 2y = -18
2x - 5y = -18

Now, we add these equations :

x - 3y = -11
-x + 2y = 7
-> x - 3y - x + 2y = -4
-y = -4
y = 4

Replace it in 2x - 5y = -18

2x - 20 = -18

2x = -18 + 20 = 2
x = 1

Recheck : 1 - 3 x 4 = -11

-1 + 8 = 7.

Step-by-step explanation:

Reduce the ratio by its halves (50 percent) and simplify.

Although for this case, you could reduce it even further, because this is a ratio, not the true height.

If this is a test, I would not recommend that.

By solving a linear equation, we can see that you should use 4lb of the $2.4/lb mix.

First, if you use x pounds of the $2.4/lb mix, the total mass of mixture that you will have is:

(x + 5lb).

And that mass must cost $1.5/lb, so the costs on the left side must be equivalent to the cost on the right side.

x*$2.4/lb + 5lb*($1.5/lb) = (x + 5lb)$1.9/lb

Now we need to solve this for x

x*$2.4/lb +  5lb*($1.5/lb) = x*$1.9/lb + 5lb*$1.9/lb

x*$2.4/lb - x*$1.9/lb  = 5lb*$1.9/lb -  5lb*($1.5/lb)

x*$0.5/lb = $2

x = $2/($0.5/lb) = 4lb

You should use 4lb of the $2.4/lb mix.

Using the Central Limit Theorem, it is found that the distribution of the sample mean of six randomly selected bottles is approximately normal, with mean 473 ml and standard error of 1.22 ml.

The Central Limit Theorem establishes that, for a normally distributed random variable X, with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the sampling distribution of the sample means with size n can be approximated to a normal distribution with mean [tex]\mu[/tex] and standard deviation [tex]s = \frac{\sigma}{\sqrt{n}}[/tex].

In this problem, for the population, we have that:

[tex]\mu = 473, \sigma = 3[/tex]

Answer:

the answer is number is the last one

Answer:

  $282

Step-by-step explanation:

The price per ticket can be found by dividing the total cost by the number of tickets, then subtracting the value of any per-ticket add-ons.

  5(x +17) = 1495 . . . . . total cost of 5 tickets with 17 per ticket ins charge

  x +17 = 299 . . . . . . divide by 5

  x = 282 . . . . . . . price of 1 ticket

The price of one ticket is $282.

Step-by-step explanation:

cosine is cos(angle)= adjacent/hypotenuse

sine is sin(angle) = opposite/hypotenuse

Tangent is tan(angle)= opposite/adjacent

for all of those

if the equation is something like tan(69)= x/69

multiply both sides by 69 so it will end up as x=69tan(69) and put that in the calculator

if it is something like tan(69)= 69/x

just swap x and tan(69)

it is much easier

it will then be 69/tan(69) and put that in the calculator

Answer:

7/12

Step-by-step explanation:

Draw a rectangle with 12 squares. 5 of them will be pop and 7 will not.

The equation will be 12/12 = 5/12 + n. You will subtract 5/12 from each side and get 7/12 = n.

Answer:

the answer is 40.8 m2

Step-by-step explanation:

The area of a figure is the amount of space the figure occupies

The surface area of the figure is 34.8 square meters

How to determine the area of the shape

From the question, we have:

The dimensions of the congruent squares are 3 m by 3 m

The dimensions of the parallelogram are height of 2.8 m, and base of 6 m

So, the area of the figure is:

Area = 2 * Area of square + Area of parallelogram

This gives

Evaluate the products

Evaluate the sum

Hence, the surface area of the figure is 34.8 square meters

so the answer is 40.8 m2

The area of a figure is the amount of space the figure occupies

Hence, The surface area of the figure is 34.8 square meters

To multiply means to add a number to itself a particular number of times. Multiplication can be viewed as a process of repeated addition.

Now, From the question, we have:

The dimensions of the congruent squares are 3 m by 3 m

The dimensions of the parallelogram are height of 2.8 m, and base of 6 m

So, the area of the figure is:

Area = 2 × Area of square + Area of parallelogram

This gives;

Area = 2 × 3 × 3 + 2.8 × 6

Area = 18 + 16.8

Area = 34.8 m²

Hence, The surface area of the figure is. 34.8 square meters

Answer:

[tex] \frac{1}{1.5} [/tex]

Step-by-step explanation:

Let B represent Bill age

A be adam age

C be charlie age

We know that

[tex]b = 2a[/tex]

We also know that

[tex]c = b - 3[/tex]

And we know that

[tex]a + b + c = 27[/tex]

Fist let subsitue c for b-3

[tex]a + b + (b - 3) = 27[/tex]

[tex]a + 2b - 3 = 27[/tex]

[tex]a + 2b = 30[/tex]

We know that b=2a so

[tex]a + 2(2a) = 30[/tex]

[tex]a + 4a = 30[/tex]

[tex]5a = 30[/tex]

[tex]a = 6[/tex]

Plug that in first equation to solve for b

[tex]b = 2(6)[/tex]

[tex]b = 12[/tex]

Finally plug that in the final equation to solve for c.

[tex]6 + 12 + c = 27[/tex]

[tex]c = 9[/tex]

Know we want the ratio of Adam age, a to Charlie age, c.

So we have

[tex] \frac{6}{9} = \frac{2}{3} = \frac{1}{1.5} [/tex]

Step-by-step explanation:

When you reflect a point across the line y = x, the x-coordinate and y-coordinate change places. If you reflect over the line y = -x, the x-coordinate and y-coordinate change places and are negated (the signs are changed). the line y = x is the point (y, x). the line y = -x is the point (-y, -x).
