To know how many there is multiply 12 and 16 to get 192 then add that to 60 to get 250

Answer:

$16.75

Step-by-step explanation:

To get the solution, we are looking for, we need to point out what we know.

1. We assume, that the number 67 is 100% - because it's the output value of the task.

2. We assume, that x is the value we are looking for.

3. If 67 is 100%, so we can write it down as 67=100%.

4. We know, that x is 25% of the output value, so we can write it down as x=25%.

5. Now we have two simple equations:

1) 67=100%

2) x=25%

where left sides of both of them have the same units, and both right sides have the same units, so we can do something like that:

67/x=100%/25%

6. Now we just have to solve the simple equation, and we will get the solution we are looking for.

7. Solution for what is 25% of 67

67/x=100/25

(67/x)*x=(100/25)*x - we multiply both sides of the equation by x

67=4*x - we divide both sides of the equation by (4) to get x

67/4=x

16.75=x

x=16.75

now we have:

25% of 67=16.75

So basically, we have [-83, -77] as the whole thing.
There's a circle that limits [-83, -79) as a shaded zone.

Vera claims that -78.9999 $\geq$ X, which is false.
Vera wrote a relation symbol that doesn't represent the ray's direction. She went the other way around.

Simplify give ur answer in index form.

kherson [118]

$\frac{( {j}^{4} \: \times \: {j}^{8}) ^{3} }{( {j}^{9} \: \div \: {j}^{2}) ^{2} }$

First we calculate the product of the denominator.

$\frac{( {j}^{12}) ^{3} }{( {j}^{9} \: \div \: {j}^{2}) ^{2} }$

Then we calculate the quotient of the numerator.

$\frac{( {j}^{12}) ^{3} }{( {j}^{7}) ^{2} }$

We multiply the exponents of the expression.

$\frac{ {j}^{36} }{ {j}^{14} }$

We divide.

$\boxed{ \bold{ {j}^{22} }}$

If your using pemdas the answer would be roughly 3.6 because you divide 8 and 3 first to get 2.6 repeated then do 2+2=4 then 4-3=1 + the original 2.6 = 3.6

Find the coordinates of the midpoint of the segment whose endpoints are H(8, 13) and K(10, 9).

Wittaler [7]

Good evening

Answer:

Step-by-step explanation:

let Point M(x , y) be the midpoint of segment HK then

x = (8+10)/2 = 18/2 = 9

y = (13+9)/2 = 22/2 = 11.
