one hectameter is =how much cm?
A=100
B=10000
C=10
D=1000​

Answer:

10mins

Step-by-step explanation:

you can draw a rtd chart for this problem

             rate (m/min)|  time (mins)  | distance (m )

regular: (300/x)  | x  | 300m

fist 1/4 : (300/x) | 75: (300/x)  | 75m

last 3/4:  | (300/x)+15 | 225:(300/x + 15) | 225m

then, make an equation for the times:

x= (75: (300/x)) + (225: ( (300/x)+15) + 2.5 = x

// get the 2.5 mins from the stop for honey, and we know that regular speed is equal to the one with a stop

solve equation to get x=-20/3 , x=10, because speed is positive, x=10 is the most reasonable answer

Answer:

Each monthly payment is of £560.

Step-by-step explanation:

Sue buys a car costing £8000 plus 20% VAT?

She has to pay:

8000 plus 20% of tax. So

[tex]T = 8000 + 0.2*8000 = 9600[/tex]

She pays £4000 deposit and then chooses to pay the balance in ten equal monthly payments.

4000 deposit, and then 9600 - 4000 = 5600 divided in ten equal monthly payments.

5600/10 = 560

Each monthly payment is of £560.

Answer:

50%

Answer:

EX :A jar contains 10 red marbles, 4 white marbles, and 2 blue marbles. Two ... To solve this question, you can solve for the probability of choosing 2 marbles that are pink and ... There are two even numbers and three odd numbers, so P (even) = 2/5 and P (odd) = 3/5. ... In a bag, there are 10 red, 15 green, and 12 blue marbles.

b.5b/8=2/5

5b=2×8/5

b=16/5×1/5=16/25

Answer:

Step-by-step explanation:

The person I sent it to couldn't see it either. I'm going to take a chance and say the Chord (AB) and the Tangent line form a 50 degree angle. If this is incorrect, I won't know, from the diagram, what else to try.

If I'm right then <OAB = 40 degrees because 90 - 50 = 40 because <AOC is a right angle (property of radii and tangents).

<ABO also = 40 (the triangle is isosceles by two legs being radii).

That means that BOA = 180 - 40 - 40 = 100

Answer:

4/3

10/3

24/3

...........

Answer:

4/3

10/3

24/3 or 8

Step-by-step explanation:

x = y - 2/3

2 - 2/3 = 2/1 - 2/3 = 6/3 - 2/3 = 4/3

y = x + 2/3

8/3 + 2/3 = 10/3

y = x + 2/3

22/3 + 2/3 = 24/3 = 8

Answer:

70%

Step-by-step explanation:

Because 100% - 30% = 70%

Answer:

sin

sin 20 = x/15

15 sin 20 =x

Step-by-step explanation:

We want to find the opp/ hyp

sin 20 = opp / hyp

sin 20 = x/15

15 sin 20 =x

math kinda sucks. :) Brainliest pls???

Step-by-step explanation:

Answer:

0.1 = 10% probability that the class length is between 51.5 and 51.7 min, that is, P(51.5 < X < 51.7) = 0.1.

Step-by-step explanation:

A distribution is called uniform if each outcome has the same probability of happening.

The uniform distributon has two bounds, a and b, and the probability of finding a value between c and d is given by:

[tex]P(c \leq X \leq d) = \frac{d - c}{b - a}[/tex]

The lengths of a professor's classes has a continuous uniform distribution between 50.0 min and 52.0 min.

This means that [tex]a = 50, b = 52[/tex]

If one such class is randomly selected, find the probability that the class length is between 51.5 and 51.7 min.

[tex]P(51.5 \leq X \leq 51.7) = \frac{51.7 - 51.5}{52 - 50} = \frac{0.2}{2} = 0.1[/tex]

0.1 = 10% probability that the class length is between 51.5 and 51.7 min, that is, P(51.5 < X < 51.7) = 0.1.

Answer:

7

Step-by-step explanation:

-2, -3 and -2, 4 have the same x coordinate, so you only need to find the difference between -3 and 4.

Answer:

To find the area of a composite figure, separate the figure into simpler shapes whose area can be found. Then add the areas together. Be sure than none of the simpler figures have overlapping areas. To calculate the area of a composite shape you must divide the shape into rectangles, triangles or other shapes you can find the area of and then add the areas back together. To find the area of a rectangle, multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area. This is the same as saying length2 or length squared.

Answer:

An expression is a syntactic construct. It must be well-formed: the allowed operators must have the correct number of inputs in the correct places, the characters that make up these inputs must be valid, have a clear order of operations, etc.

Answer:

13.5 hr.

Step-by-step explanation:

Let h = no. of hours

Total cost = 12 + 8h = 120

8h = 108

h = 13.5 hr.

Answer:

48

Step-by-step explanation:

Remark

Use a^2 + b^2 = c^2 to solve for the height.

Givens

c = 10

b = 6

h = ?

Solution

b^2 + h^2 = c^2

6^2 + h^2 = 10^2

36 + h^2 = 100            Subtract 36

h^2 = 100 - 36

h^2 = 64                      Take the square root of both sides

sqrt(h^2) = sqrt(64)

h = 8

The height = 8

Area = 1/2 * b * h

Area = 1/2 *12 * 8

Area = 48

You might wonder where the 12 came from. It wasn't given The base is the whole line across the bottom. 1/2 of it is six. The whole base = 12
