Answer:

x=58 degrees

Step-by-step explanation:

A line is 180 degrees. So x+90+32=180. 32+90=122. Now you do 180-122 and you will get 58.

Answer:

936mm^2

Step-by-step explanation:

Surface area of cuboid 20 mm 8mm 11mm

Surface area of the cuboid=2(20×8+8×11+11×20)

=2(160+88+×220)

=2(468)

=936mm^2

So the answer is936mm^2

Starting with some solution of volume v and an alcohol concentration of 100c % , if you add 180 mL of 45% isopropyl to it, you get a mixture with a total volume of 180 mL + v.

Each mL of the starting solution contains c mL of alcohol. For example, if the concentration of the starting solution is 80% (so c = 0.8), then each mL contains 80% = 0.8 of one mL of alcohol.

Similarly, each mL of the added solution with 45% concentration contains 0.45 mL of alcohol.

You want the new solution to have a concentration of 70%, so that the ratio of the amount of alcohol in it to the total volume is 70%, meaning

cv + 0.45 (180 mL) = 0.7 (180 mL + v)

and you want to solve for v :

cv + 81 mL = 126 mL + 0.7v

cv - 0.7v = 126 mL - 81 mL

(c - 0.7) v = 45 mL

v = (45 mL) / (c - 0.7)

Judging by context clues, c lies somewhere between 0.7 and 1. (It can't be less than 0.7 because mixing this solution with any other solution of smaller concentration will never yield a solution of higher concentration.)

If, for example, c = 0.8, so that your starting solution is at 80% concentration, then you would need

v = (45 mL) / (0.8 - 0.7) = 450 mL

to be mixed with 180 mL of 45% solution to end up with 180 mL + 450 mL = 630 mL of 70% solution.

As another example, if you're mixing pure alcohol, so that c = 1, you would need

v = (45 mL) / (1 - 0.7) = 150 mL

to make a 180 mL + 150 mL = 330 mL batch of 70% solution. The fact that you would need less of a higher concentration solution is not surprising.

Answer:

Density

Step-by-step explanation:

The gram per centimeter cubed is a unit of density in the CGS system, normally used in chemistry, defined as mass in grams divided by volume in cubic centimeters. The official SI symbols are g/cm3, g·cm−3, or g cm−3.

Answer:

1) 16

2) 35

3) 60 degrees

4) 72 degrees

5) (x+7)= 55 y= 70

Step-by-step explanation:

1) Special Triangle - All angles are 60 degrees, so that means all sides are the same length

2) You know that those two angles at the end are the same, so that means each of those side lengths are mirrored.

3) Special Triangle - Each side is the same, so all angles would be 60 degrees

4) You know that those two sides are the same, so their angles would be mirrored

5) You know that those two sides are the same, so their angles would be mirrored, to get 55 on both bottom sides. 55+55= 110 so, you'd need 70 degrees left to make it a triangle as all triangles are fully 180 degrees.

Answer:

They are perpendicular

Step-by-step explanation:

If 2 slopes are negative reciprocals of each other, it means they are perpendicular

Answer:

The lines are perpendicular because they have opposite reciprocal slopes.

Answer: y=1, x=11

Step-by-step explanation: make x in one side in an equation and substitute it in the other and get the value of y then substitute y in one of the equations and get the value of x

x= 8+3y

8+3y+6y=17

9y=9

y=1

X=11

Answer: 1/2

Step-by-step explanation:

I think the slope is 1. hope that helps

Answer:

0.50

Step-by-step explanation:

To answer this question, we have the following data available:

Probability of randomly chosen death caused by a heart disease = 0.27

Probability of randomly chosen death caused by cancer = 0.23

We are to calculate the probability that the death was as a result of either cancer or heart disease.

P(cancer or heart disease)

= 0.27 + 0.23

= 0.50

Thank you!
