Answer:
Step-by-step explanation:
∠A + ∠B = 90 {∠A & ∠B are complementary}
x + 16 + x - 12 = 90
x + x + 16 - 12 = 90 {Combine like terms}
2x + 4 = 90 { Subtract 4 form both sides}
2x = 90 - 4
2x = 86 {divide both sides by 2
x = 86/2
x = 43

Total Quantity of Blue and white paint =6.2 pints
Quantity of White paint =2/ 5 x 6.2 pints = 2.48 pints
Quantity of blue paint =Total Quantity -Quantity of White paint
=6.2 pints-2.48 pints
=3.72 pints

A bucket of paint has spilled on a tile floor. The paint flow can be expressed with the function r(t) = 3t, where t represents time in minutes and r represents how far the paint is spreading.
The flowing paint is creating a circular pattern on the tile. The area of the pattern can be expressed as A(r) = πr2.
Part A: Find the area of the circle of spilled paint as a function of time, or A[r(t)]. Show your work.
Part B: How large is the area of spilled paint after 10 minutes? You may use 3.14 to approximate π in this problem.

What is the slope and y intercept of 3x = 9y-9
Answer:
y = 1/ 3 x − 1
Step-by-step explanation:
y intercept is -1 and slope is 1/3x
The slope and y-intercept will be [tex]\rm m=\frac{1}{3} \ and \ c=-1[/tex]. The slope and the intercept are found with the help of the standard equation;
What is the slope?A numerical assessment of a line's angle relative to the ground is known as the slope.
The inclination of any line, ray, or line segment is the fraction of the perpendicular to the horizontal distance between any two positions on it.
The given linear equation in the problem is;
[tex]\rm 3x = 9y-9[/tex]
On dividing the whole equation by 3 we will get;
[tex]\frac{1}{3} x=y-1 \\\\ y= \frac{1}{3} x+1[/tex]
Compare the equation with the standard equation;
[tex]\rm y = mx+c[/tex]
Where m is the slope and c is the intercept. After comparing we will get;
[tex]\rm m=\frac{1}{3} \\\\ c=-1[/tex]
Hence the slope and y-intercept will be [tex]\rm m=\frac{1}{3} \ and \ c=-1[/tex].

3cm and a density of
20g/cm3
Answer:
work out the area which is 4x5x3 this being 60 then divide this by 20 to get 3
The answer is 3kg
Answer:
[tex]density = mass \div volume \\ 20 = x \div 4 \times 3 \times 5 \\ 20 = x \div 60 \\ 20 \times 60 = x \\ x = 1200 \\ 1200 \div 1000 = 1.2kg[/tex]
