Anna and Betty share 24 sweets in the ratio 3:5. How many sweets do they get each?
Answer:
Anna 9 and Betty 15
Step-by-step explanation:
sum the parts of the ratio , 3 + 5 = 8 parts
divide number of sweets by 8 to find value of one part of the ratio
24 ÷ 8 = 3 ← value of 1 part of the ratio , then
3 parts = 3 × 3 = 9
5 parts = 5 × 3 = 15
Anna gets 9 sweets and Betty gets 15

Answer:
Step-by-step explanation:
Given the x-intercepts at -1 and 5, that means y=0 at x=-1 and x=5.
So (x+1) and (x-5) are root for the parabola.
y = (x+1)*(x-5)
That is the quadratic equation for Question B.
Back to A, the x-coordinate of vertex of this parabola is at x=2.
This is because the parabola is symmetrical at its vertex so the vertex must be at the mid-point between its x-intercepts, x=(-1+5)/2=2.

For the given similar polygons, the value of x equal to 30.
Similar PolygonsTwo polygons are classified as similar when their angles are congruent and their sides are proportional.
If the polygons of this exercise are similar. You can write:
[tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}[/tex]
Then,
[tex]\frac{LK}{QR}=\frac{JK}{PR}=\frac{JL}{PQ}\\ \\ \frac{18}{12}=\frac{x}{20}=\frac{21}{14}[/tex]
It is possible to note that the scale factor is [tex]\frac{3}{2}[/tex]. See it.
[tex]\frac{18:6}{12:6}=\frac{3}{2} \\ \\ \frac{21:7}{14:7}=\frac{3}{2}[/tex]
Therefore, you can find x from:
[tex]\frac{18}{12}=\frac{x}{20}\\ \\ 12x=18*20\\ \\ 12x=360\\ \\ x=\frac{360}{12} =30[/tex]

The ordered pairs in the table lie in the graph of the linear function whose equation is
y = 3x + 2.
Which ordered pair does not lie on the graph of this function?
A. (10, 32)
B. (8, 13)
C. (–5, –13)
D. (–8, –22)
y = 3x + 2 = 3 * x + 2
point (10 ; 32) on the line ?
so here we can read : x = 10 and y = 32
if x = 10
then y has to be = 3 * 10 + 2 = 30 + 2 = 32
so yes - on the line
same reasoning for the rest
The ordered pairs which does not lie on the graph of the function are (8,13).
What is function?Function is relationship between two or more variables expressed in equal to form. In a function each value of x must have corresponding value of y.
The value which we put in the function is domain of the function and the value which we will get is known as codomain of the function.
How to find ordered pairs?We have been given a function y=3x+2 and we have to find the ordered pairs which does not lie on graph of function. The ordered pairs which lie on the graph must satisfy the function and the ordered pairs which does not lie on the graph must not satisfy the function.
First ordered pair is (10,32)
32=3*10+2
32=30+2
32=32
It lies on graph.
Second ordered pair is (8,13)
12=3*8+2
12=24+2
12≠26
So it does not lie on graph of function y=3x+2.
Hence the ordered pair which does not lie on the graph of function y=3x+2 is (8,13).

Range of a function is the extent to which any function may be varied. The range of the given function y= -3sin(x)-4 is [-7,-1].
What is a Range?The range of a function is the extent to which any function may be varied.
We know that the general range of the function of sin(x) is between [-1,1].
-1 ≤ sin(x) ≤ 1. . . . . . . . . .(A)
As our required function is y = -3sin(x) - 4
Now, in order to get this function, we will multiply each side in Equation (A) by -3, therefore,
-3 ≤ -3 sin(x) ≤ 3
Further, subtract from 4 from each side of the equation.
-7 ≥ -3sin(x)-4 ≥ -1
Hence, the range of the given function y= -3sin(x)-4 is [-7,-1].

Write the following ratios in its simplest form 56:112:28
Answer:
2 : 4 : 1
Step-by-step explanation:
First take common factors by factorization.
56 = 14 x 4 = 28 x 2
112 = 14 x 8 = 28 x 4
28 = 14 x 2 = 28 x 1
Remove the 28 common factor.
Therefore,
56 : 112 : 28
