Answer=17 km in 30 min
Answer:
See below.
Step-by-step explanation:
This problem and the answers don't work.
The way the problem is written, the answer is 17 km.
There is no such answer.
There is a mistake somewhere.
If the man is walking at the speed of 3/4 km/h, then in 30 minutes, which is half of 1 hour, he walk 3/8 km. There is no answer of 3/8 km in the choices.

What is the area of the triangle abc?
Answer:
Your answer is 35!
Step-by-step explanation:
I'm sure of it!
table shows pairs of coordinates. Plot these in the coordinate plane. Be sure to label the axes.
Answer:
I'm not sure how I can show you because you have to plot the points, not give a straight answer but I'll give you an idea.
Step-by-step explanation:
POINT 1: For the first point you are going to find 4 on the X axis and go up by 3. Plot your point there
POINT 2: Find the number 2 on the X axis and go up by 6
BTW keep in mind that the X axis is the the horizontal line that divides the coordinate plane half. If you folllow my intrustions for the first 2 points, you'll get an idea of how to grph the 3rd point!

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].

Answer:
6.8
Step-by-step explanation:
This is the answer because:
1) The square root of 46 is 6.78232998...
2) The nearest tenth of this is 6.8 because we have to round 7. Since 8 is greater than 5, we have to round 7 up.
Therefore, the answer is 6.8

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
= 2 : 4 : 1

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.

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).

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
