23.21 to the nearest hundredth​

2 hours. It's extremely simple this is elementary grade, he needs to travel 25 miles and he's going 12.5 miles an hour, 12.5 x 2 = 25 So in 2 hours he reaches his destination.

The time it will take will be 5 hours.

"The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity. Ratios can be classified into two types. One is part to part ratio and the other is part to whole ratio. The part-to-part ratio denotes how two distinct entities or groups are related. For example, the ratio of boys to girls in a class is 12: 15, whereas, the part-to-whole ratio denotes the relationship between a specific group to a whole. For example, out of every 10 people, 5 of them like to read books. Therefore, the part to the whole ratio is 5: 10, which means every 5 people from 10 people like to read books."

The speed of the bike = 12.5 miles/hour

So, the distance will be = [tex]25/2 * 5 = 125/2[/tex]

Time taken = [tex]125/2 * 1/12.5[/tex]

= 5 hours

Hence, the time taken to get to the zoo = 5 hours

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

Answer:

4.69 feet

Step-by-step explanation:

If the table is a square, all the sides are equal and the area is the length of one side squared.  A=l^2

The length must then be the square root of the area. The square root of 22 square feet is 4.6904 feet. Rounded to the nearest tenth, that is 4.69 feet.

THATSS ALL I NOW IT SOO GOOD

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:

Step-by-step explanation:

jk get that work

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: 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:

1 1/2 = 3/2

1/3 * 3/2 = 1/2

Answer: acute

Step-by-step explanation: it is less than 90 degrees so it is less the right angle

120 degrees.

Angle MNT is equal to its opposite angle, (I cant tell you the angle as one of the points is not showing, it uses T and Q)

Remember, all triangles have angles that when added together, equal 180 degrees.

So, add 35 and 25, which is 60.

Now subtract 60 from 180, 120.

Have a great day!
