Point E is located at (–5, 2). Point M is the reflection of point E across the y-axis. What is the distance between E and M?

1 answer:

3 0

The distance between E and M will be twice the distance from either to the y-axis. That distance is given by their x-coordinates.

The distance between E and M is 10 units.

Write a proportion using the ratio WV/WX. Pls help ASAP!!

algol13

Answer:

$\frac{WV}{WX}=\frac{VY}{VX}$

Step-by-step explanation:

we know that

In the right triangle WVX

$cos(W\°)=\frac{WX}{WV}$

Remember that

$cos(W\°)=sin(Y\°)$ ------> equation A

Because are complementary angles

In the right triangle VXY

$sin(Y\°)=\frac{VX}{VY}$

substitute the values in the equation A

$\frac{WX}{WV}=\frac{VX}{VY}$

Rewrite the expression

$\frac{WV}{WX}=\frac{VY}{VX}$

Karl’s and eddie’s ages added together are equal to 65. 10 years ago, Karl was twice as old as Eddie. How old are they now

trapecia [35]

Answer:

Karl is 40
Eddie is 25

Step-by-step explanation:

10 years ago, the sum of their ages was 65 -2·10 = 45.

If Karl was twice as old as Eddie, his contribution was 2/3 of the sum and Eddie's was 1/3. That is, Karl was (2/3)(45) = 30 and Eddie was 15 at that time.

Now, Karl is 40 and Eddie is 25.

This can be solved using a system of equations.

e = 65 -k

(k -10) = 2(e -10)

Substituting the first equation into the second gives ...

k -10 = 2((65 -k) -10)

k -10 = 110 -2k . . . . . . . simplify

3k = 120 . . . . . . . . . . . . add 10+2k

k = 40

e = 65 -40 = 25

Jessie has a container that contains 18 3/4 cios of ice cream. How many 1/3-cup servings of ice cream are in the container

ladessa [460]

Hi there!

18 × $\frac{3}{4}$ = amount of ice cream in container

13.5 = amount of ice cream in container

Let's replace the number of cups by "C" :

13.5 = C × $\frac{1}{3}$

Isoltate "C" by dividing each side of the equation by $\frac{1}{3}$

40.5 = C

Which means that your answer is : There are 40.5 1/3-cup servings of ice creamin the container!

There you go! I really hope this helped, if there's anything just let me know! :)
