$88
Explanation:
Adults $12x5 = 60
Child $7x 4=28
60+28=88
Answer:
Shape a has 1 order of rotational symmetry and 1 line of symmetry
Shape b has 2 orders of rotational symmetry and 0 line of symmetry
Rotational symmetry is how many times a shape can be rotated and look the same.
Lines of symmetry are how lines can be put through the shape to make it symmetrical or the same on both sides
Answer:
From general equation of a line:

m » slope, b » y-intercept.
but perpendicularly:

at point (6, 2):

therefore, equation is :

Answer:
<em>The rate of the equation is r when r is a constant</em>
Step-by-step explanation:
We need to solve for the rate of the equation
d = rt
Differentiating on both sides with respect to time
= 
Considering r as a constant
= r×
where,
= 1
= r
<em> The rate of the equation is r when r is a constant</em>
<em> </em>
The equation: 6r-3=45
6r=48
Answer: r=8
