A staining solution bottle in a medical laboratory contains 30 ounces (oz). A blood staining test requires 3/4 oz of solution. A

tissue staining test requires 1/2 oz of solution. If four blood tests and five tissue tests are performed, how many oz of solution are left in the bottle

Answer:

24.5 oz

Step-by-step explanation:

First lets calculate the blood tests, 3/4 oz of solution.

3/4 multiplied by four tests= 3. (.75*4=3)

So 3 oz of Blood Tests were performed, now lets calculate the amount of tissue staining tests for performed.

1/2 multiplied by five tests= 5/2 or 2.5 oz of tests. (.5*5=2.5)

3oz+2.5=5.5oz

Now let's subtract that amount by 30.

30-5.5=24.5

A line passes through the points (6,5) and (2,2) . Select Yes or No to tell whether each equation describes this line. Equation
Marta_Voda [28]

ANSWER

y-5=\frac{3}{4}(x-6),Yes

y-5=-\frac{4}{3} (x-2),NO

y-2=-\frac{3}{4} (x-6),NO

y-2=\frac{3}{4}(x-2),Yes


EXPLANATION

The line passes through these two points, (6,5) and(2,2).


We can use these two points to determine the slope of the line.

The formula for finding the slope of a line when at least two points are known is m=\frac{y_2-y_1}{x_2-x_1}.


We can choose (x_1,y_1)=(6,5) and (x_2,y_2)=(2,2) or (x_1,y_1)=(2,2) and (x_2,y_2)=(6,5).


We shall get the same result.


m=\frac{2-5}{2-6} =\frac{-3}{-4} =\frac{3}{4}.


We now determine the equation of the line using the poit-slope formula,


y-y_1=m(x-x_1).


When we choose (x_1,y_1)=(6,5), then we will obtain,


y-5=\frac{3}{4}(x-6) as the point-slope form.


When we choose (x_1,y_1)=(2,2), then we will obtain,


y-2=\frac{3}{4}(x-2) as the point-slope form.

What is the missing number pls help
aivan3 [116]

Answer:

So in order to find the missing number, we must find the difference with the numbers that we were given.

Problem #1

42-30= 12 and 84-69= 15. It's possible that each difference increases by one Let's see...

30+12= 42

42+13= 55

55+14 = 69

69+15 = 84

So for 1., all you have to do is keep adding the difference and increase it by 1 each time. If you wanted to keep increasing, you would add 84+16, then 100+17, etc.

Problem #2: As for the second one, I had trouble solving it, sorry :(.

Problem #3

3. For the third problem, 27-22= 5 and 9-1=8. It looks like each difference increased by 1.

27-22 = 5

22-6 = 16

16-7 = 9

9-8= 1

valina [46]

Yes. It is a wise financial decision because lots of places can be up to 1,000 a month. You would be taking 1,000 out of your check. Giving you only $1,000 for grocerys, car payment, insurence, etc. Only paying $500 can lead to you having more money for other thing. Maybe you wanna go out with your friends, ok? You are spending $1,000 on your apartment and don't have the money, as to where if you are only spending $500, you would have the money to go out and have fun. So, it is a very wise financial decision.


Hope this helped!
