For this question, I would first see what one child is equal toby divide the children by the percentage.
15÷3= 5
Each child is worth 5%. If you know each child is worth 5%, and the total number of students are 100%, then you can divide.
100÷5= 20
There are 20 students in the class. To make sure our answer is right, we can check to see if 3 students are 15 percent.
3÷20= .15×100= 15
So yes, there are 20 students in the class.

How would I solve this and what’s the answer ?

natali 33 [55]

To solve this you just move the letters and numbers around until you get a different equation that is the same as the original equation.

You can also rule out the last two answers because they don’t have all the values.

P = pie

s=2prh can be written as s/2ph=r if we divide s by 2ph because we need to isolate r because all the answers have r isolated.

So the answer would be b s/2ph=r

Sorry that’s really badly worded and confusing, but I hope it helps.

If you are given the graph of h(x) = log6X, how could you graph m(x) =log6(X+3)?

bonufazy [111]

Answer:

Translate each point of the graph of h(x) 3 units left ⇒ 4th answer

Step-by-step explanation:

Let us revise the translation of a graph

If the function f(x) translated horizontally to the right by h units, then its image is g(x) = f(x - h)
If the function f(x) translated horizontally to the left by h units, then its image is g(x) = f(x + h)
If the function f(x) translated vertically up by k units, then its image is g(x) = f(x) + k
If the function f(x) translated vertically down by k units, then its image is g(x) = f(x) - k

∵ $h(x)=log_{6}(x)$

∵ $m(x)=log_{6}(x+3)$

∵ x in h(x) is changed to (x + 3) in m(x)

- From the 2nd rule above, that means the graph of h(x)

is translated 3 units to the left

∴ The graph of h(x) is translated 3 units to the left

∴ Each point on the graph of h(x) is translated 3 units to the left

∴ Translate each point of the graph of h(x) 3 units left

Look to the attached figure to more understand

The red line represents h(x)

The blue line represents m(x)

In parallelogram DEFG, DH = x + 2, HF = 2y, GH = 4x - 3, and HE = 5y + 1. Find the values of x and y. The diagram is not to scal

Svetllana [295]

Answer:

x = 6, y = 4

Step-by-step explanation:

The diagonals of a parallelogram bisect with each other at the point of intersection with equal sides across the point of intersection.

DH = HF ⇒ x + 2 = 2y
GH = HE ⇒ 4x - 3 = 5y + 1

x + 2 = 2y,

4x - 3 = 5y + 1

x = 2y - 2,

4(2y - 2) - 3 = 5y + 1

x = 2y - 2,

8y - 8 - 3 = 5y + 1

x = 2y - 2,

8y - 11 = 5y + 1

x = 2y - 2,

8y - 5y = 11 + 1

x = 2y - 2,

3y = 12

x = 2y - 2,

y = 4

x = 2*4 - 2,

y = 4

x = 6,

y = 4

Find the third angle in a triangle when the other two angles are (2a-32)° and (3a+22)°

kati45 [8]

Answer:

(190-5a)°

Step-by-step explanation:

Sum of internal angles of a triangle equals to 180°

If the third angle is x, then we have:

(2a-32)°+(3a+22)° +x = 180°
(5a- 10)° +x= 180°
x= (180+10-5a)°
x= (190-5a)°

The third angle is: (190-5a)°
