Okay so let’s start by figuring what the total number of people is. To get that we add 24 and 30.
24+30= 54
So we have a total of 54 people.
Now, how many children are there?
30 children... which means the ratio is 30:54

Thirty children to fifty four people total at the museum.

Hope this helps!

Answer:

  WX = 33

  (x, y) = (2, 10)

Step-by-step explanation:

The hash marks tell you WX is a midline, so has the measure of the average of the two bases.

  WX = (PQ +SR)/2 = (27 +39)/2 = 66/2

  WX = 33

__

The hash marks also tell you ...

  PW = WS

  y +4x = 18 . . . . . . substitute the given expressions

and also

  QX = XR

  2y +x = 22 . . . . . substitute the given expressions

__

If you solve the first equation for y, you get ...

  y = 18 -4x

Substituting that into the second equation gives ...

  2(18-4x) +x = 22

  36 -7x = 22 . . . . . . . simplify

  14 = 7x . . . . . . . . . . . add 7x-22 to both sides

  2 = x . . . . . . . . . . . . divide by 7

  y = 18 -4(2) = 10 . . . find y using the above relation

The values of x and y are 2 and 10, respectively.

__

My favorite "quick and dirty" way to solve a set of linear equations is using a graphing calculator. It works well for integer solutions.

Find the value of x in the triangle (not drawn to scale.)
AlekseyPX

Your answer would be 29

Why?

Because that is a right angle. They always have to be 90° so 90-61=29

Julia has to mow two yards she will need 13/16 gallon of gas to mow the first yard and 2/5 gallon to mow the second yard she has
Mazyrski [523]

Answer:

Julia has  enough gas to mow the two yards.

Step-by-step explanation:

Given:

Julia needs \frac{13}{16} gallon of gas to mow first yard.

Julia needs \frac{2}{5} gallon of gas to mow second yard.

Julia has a total of 1\frac{1}{2} gallon of gas in in her can.

To find whether she has enough to mow both yards.

Solution:

Total gallons of gas needed to mow two yards can be found out by :

⇒ \frac{13}{16}+\frac{2}{5}

Taking LCD =80.

⇒ \frac{13\times 5}{16\times 5}+\frac{2\times 16}{5\times 16}

⇒ \frac{65}{80}+\frac{32}{80}

Adding the numerators.

⇒ \frac{97}{80}

⇒ 1.2125 gallons

Julia has 1\frac{1}{2} gallon = 1.5 gallons of gas in in her can.

Since  1.5>1.21 , thus we can say that Julia has enough gas to mow the two yards.

Suppose h(t) = -4t^2+ 11t + 3 is the height of a diver above the water (in
Bingel [31]
The diver will hit the water when the height is zero, so we will want to set our height function equal to zero
0 = -4t^2 + 11t + 3
we will then factor to find out value of t that make the function equal to zero
0 = (-4t - 1 ) ( t - 3 )
This means our function equals zero when t = -1/4 s and t = 3 seconds
Since time cannot be negative, our final solution is t = 3 seconds
