If in four seconds, she can type six words, then we can guess that in eight seconds (4x2) she can type twelve words (6x2). Now, thats only for eight seconds, and we need two more to make ten. In four seconds, she types six words, so we need only two seconds, which would be half of six (3). And the 12+3 gives us 15 words in ten seconds. Sorry if its wrong, but hope i helped somehow :)

How many halves are in three wholes
vlabodo [156]

Answer:

6

Step-by-step explanation:

1/2 + 1/2 = 1

1/2 + 1/2 = 1

1/2 + 1/2 = 1

There are 6 halves that equal 3.

Another way to do this is:

1/2x = 3

3 / 1/2 = 6

x = 6

Can anyone please help me what is x<br>​
Masja [62]

Step-by-step explanation:

the side on the left of 155 is 180-155 which is 25

the one on top of 120 is 180-120 which is 60 so the one on the right of x is 180-(25+60) which is 95

now the value of x is 180-95 which is 85.

in the second one x=180-100 because the angle on the bottom of x is corresponding to the one that's equal to 100, so x=180-100 which is 80

for the first one x=85

the second one x=80

Mary wants to fill in a cylinder vase. At the flower store they told her that the vase should be filled 3/4 for the flowers to
Alex Ar [27]

Answer:

About 376.99 cubic inches

Step-by-step explanation:

Cylinder has a volume of:

V=\pi r^2h

Where

V is the volume

r is the radius

h is the height

We need to find the volume of the cylinder, then multiply that answer by 3/4 to get the solution to this problem. First, the full volume of the cylinder.

Given

r = 4

h = 10

So,

V=\pi r^2h\\V=\pi (4)^2 (10)\\V=502.65

Now, we multiply by 3/4:

502.65*\frac{3}{4}=376.99

Mary should be vase to 376.99 cubic inches

Solve the equation 4*e+2=1 (mod5)
otez555 [7]

Here's a way to do it.

Let 4e +2 = 5n +1 . . . . . . for some integer n

Then e = (5n -1)/4 = n + (n -1)/4

We want (n-1)/4 to be an integer, so let it be integer m.

... m = (n -1)/4

... 4m = n -1

... 4m +1 = n

Substituting this into our expression for e gives

... e = (5(4m+1) -1)/4 = (20m +4)/4 = 5m +1

e = 5m+1 for any integer m
