Answer:
31, 43, 57
Step-by-step explanation:
Work out the differences between the terms of the sequence:
[tex]1 \underset{+2}{\longrightarrow} 3 \underset{+4}{\longrightarrow} 7 \underset{+6}{\longrightarrow} 13 \underset{+8}{\longrightarrow} 21[/tex]
The differences between terms increase by 2 each time.
Therefore, from inspection of the pattern, the next three terms in the sequence are:
21 + 10 = 3131 + 12 = 4343 + 14 = 57If x and y are in direct proportion and y is 80 when x is 10, find y when xx is 15.
Answer:
y = 120
Step-by-step explanation:
If x = y, they can be written as a fraction to show their proportionality as [tex]\frac{10}{80}[/tex]. This is equal to [tex]\frac{1}{8}[/tex], so when x = 1, y = 8. To find when y is equal to x when x = 15, just multiply y by 15. 15(8) = 120, so y = 120 when x = 15.
Answer:
120
Step-by-step explanation:
set up a proportion: 80/10=y/15
solve: 80*15=10y
1200=10y
y=120

Answer:
Marc: 8 meters & 4 seconds
Prisha: 6 meters & 3 seconds
Step-by-step explanation:
Marc: If Marc travels 8 meters in 4 seconds it means that he has a speed of 2m/s
Prisha: If Prisha travels 6 meters in 3 seconds it means that she has a speed of 2m/s
To find speed we simply have to divide distance by time
The way that I figure out the answer was by trial and error. This is when we have to get random numbers and try them.

Which is an equation of a direct proportion?
The correct answer is y = -2x.
Direct proportion can also be known as Direct variation. When the ratio of two quantities equals constant, we call it Direct Proportion. Direct Proportion is denoted by [tex]\alpha[/tex] .
Let us consider two quantities a and b, then the direct proportion between a and b can be expressed as,
a [tex]\alpha[/tex] b
=> [tex]a/b = k[/tex] ( where k is constant)
=> [tex]a = kb[/tex] [tex]--- >[/tex] 1
Substitute a=x and b=y in 1, and then we get
[tex]x = ky[/tex]
Therefore, the general form of an equation which satisfies direct proportion is x = ky.
[tex]y=1/2x-2, y=-2x+3,y=4/x[/tex] are not in the form of [tex]x = ky[/tex].
So, The equation of direct proportion is y = -2x.

Draw a right-angled isosceles triangle and write its measures.
Answer:
45 ∘,45 ∘ ,90 ∘
Step-by-step explanation:
Since, the angle is right angled isosceles triangle. One of the angles will be 90 ∘
. let the other two angles be x
Thus, sum of angles = 180
90+x+x=180
2x=90
x = 45 ∘
The measure of each angle is: 45 ∘ ,45 ∘ ,90 ∘
