Answer: 1.25 litres
Step-by-step explanation:
Two litres of paint is sufficient to paint 1 ⅗ doors.
To find out the amount of paint needed to paint one door, you can use direct proportion:
2 litres : 1 ⅗ door
x 1 door
Cross multiply to get:
1 ⅗ x = 2
x = 2 / 1 ⅗
x = 2 ÷ 8/5
x = 2 * 5/8
x = 1.25 litres
Which expression represents all the solutions to the inequality
3(2x - 8) > 4x + 26?
Answer:
x > 25
Step-by-step explanation:
3(2x−8)>4x+26
Step 1: Simplify both sides of the inequality.
6x−24>4x+26
Step 2: Subtract 4x from both sides.
6x−24−4x>4x+26−4x
2x−24>26
Step 3: Add 24 to both sides.
2x−24+24>26+24
2x>50
Step 4: Divide both sides by 2.
2x

Answer:
x = 122°
Step-by-step explanation:
since it is a right triangle, the sum of the other 2 interior angles = 90°
the angle opposite x = 90° - 32° = 58°
58° and angle x are supplementary angles. Their sum is 180°.
180° - 58° = 122°

Answer:
The Y intercept is two
Step-by-step explanation:
The y intercept is the point on a graph where the graph crosses the y axis.
Basically, it is the value of y when x is 0 is (x,y)
Looking at the attached graph, our y intercept is (0,2), meaning that the y-intercept is 2.
The answer is: the Y-INTERCEPT is 2
What is the value of triangle in the equation shown? 8 x 4 = (triangle x 7) - (triangle x 3)
9514 1404 393
Answer:
triangle = 8
Step-by-step explanation:
The right side can be factored so that you have ...
8 x 4 = (triangle x 7) - (triangle x 3)
8 x 4 = triangle x (7 - 3) . . . . use the distributive property
8 x 4 = triangle x 4 . . . . . . simplify
8 = triangle . . . . . . . . . . divide both sides by 4

Number 3 determine the inverse
Answer:
So Imma use the explanation area to answer this (I'll link a video on how I solved this.)
Step-by-step explanation:
F(x)=1/3(-5x -4)³-3 (Multiply 1/3 by -5x & -4. Be sure to move the unused parts of the equation down)
F(x)= -1.66x -1.33³-3 (Here we need to use our exponent)
F(x)= -1.66x -2.37 -3 (Here we need to subtract -3 from -2.37)
F(x)= -1.66x - 0.629 (You need to subtract 0.629 from the right side and left side)
-0.629 = -1.66x (Now since X is attached by multiplication, we need to divide both sides by -1.66)
0.378 = x (this means that your inverse is 0.378)

A patient who originally weighed 340 pounds lost 60 pounds. What percent of his original weight did he lose?
Answer:
82.35%
Step-by-step explanation:
60 divided by 340=0.17647058823
Multiply that by 100 and you get 17.647058823
Next, round and you get 17.65
100-17.65=82.35

Answer:
The slope of the graph is 21.875 mi/gal
Step-by-step explanation:
What we simply have to do here is to calculate the value for the slope of the graph
Firstly, let us take out two
points to use in the slope formula
We have;
(0,0) , (8,175)
The slope equation is;
m = (y2-y1)/(x2-x1)
m = (175-0)/(8-0) = 175/8 = 21.875 mi/gal

What is the volume of this prism?
Answer:
160 u^3
Step-by-step explanation:
For the sake of ease, I will split this prism into 2 prisms. One prism will be 2x4x5 while the second one will be 4x5x6. The volume of the prism will be the sum of the volume of both prisms.
Prism A: Volume would be lwh or 2*4*5=40
Prism B: Volume would also be lwh which is 4*5*6=120
40+120=160
The volume is 160 units^3

Lmk if you have any questions!
Have a great day! :)
Answer:
100 by 190 in.
Step-by-step explanation:
Ratios are only equal if both numbers are divided by the same number.
10 : 19 = (10 × 10) : (19 × 10)
10 : 19 = 100 : 190
You have not mentioned if there is more than one answer so lets check the rest:
10 : 19 = (10 × 10.7) : (19 × 10 and 3/19)
10 : 19 ≠ 107 : 193
10 : 19 = (10 × 10.7) : (19 × 10)
10 : 19 ≠ 107 : 190
10 : 19 = (10 × 10) : (19 × 10 and 3/19)
10 : 19 ≠ 100 : 193

What is the measure of ZXZY?
Answer:
measure of angle XZY = 52 degrees
Step-by-step explanation:
The sum of measure of angles of a circle is 360 degrees.
therefore, m(arc XY) = 360 - (110 + 146)
m(arc XY) = 360 - 256
= 104 degrees
angle XZY is an inscribed angle.
By the inscribed angle theorem, the measure of an inscribed angle is half the measure of the intercepted arc.
So, m( angle XZY) = 1/2 * 104
= 52 degrees.

what is pi and how invented it??
Answer:
Step-by-step explanation:
The Egyptians calculated the area of a circle by a formula that gave the approximate value of 3.1605 for π. The first calculation of π was done by Archimedes of Syracuse (287–212 BC), one of the greatest mathematicians of the ancient world.
Answer:
π is a mathematical constant. Its commonly used value is 3.14. There is a expanded value for π. It appears in many formulas in all areas of mathematics and physics. In maths, it is commonly used for solving of circles and spheres.
The π was invented by Archimedes of Syracuse. He was one of the greatest mathematicians of the ancient world.
21) Two functions each have an initial value of 1. One function is linear and has a slope of 10
while the other function is exponential with a growth factor of 1.1.
A) At what x-value does the exponential function's output exceed the linear?
Answer:
A) x = 68.55
Step-by-step explanation:
The initial value of a function can be the value of the function when x = 0.
So we have a linear equation:
f(x) = a*x + b
with a slope of 10, then:
f(x) = 10*x + b
and we know that:
f(0) = 1 = 10*0 + b
1 = b
Then the linear function is:
f(x) = 10*x + 1
And we have an exponential function g(x)
A general expoential function is written as:
A*(r)^x
where r is the growth factor, here we know that it is equal to 1.1
Then:
g(x) = A*(1.1)^x
And we know that:
g(0) = 1, then:
A*(1.1)^0 = A*1 = 1
Then A = 1
g(x) = (1.1)^x
So our two functions are:
f(x) = 10*x + 1
g(x) = (1.1)^x
We want to find the value of x such that the exponential function's output exceeds the linear one. This is kinda hard to do analytically, so we can do it graphically.
Below you can see the graphs of both functions, where we can see that for x = 68.55, the exponential function's output exceeds the one of the linear function.
If we want to find the point analytically, we need to solve:
10*x + 1 = (1.1)^x
Which is a transcendental equation, which means that can not be solved in close form. So usually we solve them graphically.
Here we can also check that for the found value:
g(68.55) = (1.1)^68.55 = 687
f(68.55) = 10*68.55 + 1 = 685.6
So this is not the exact value at which g(x) overcomes f(x), but is a good approximation.

Answer:
in right angled triangle MNO
relationship between base and hypotenuse is given by cos angle
cosx°=b/h
cosx°=OM/MN
x°=cos-1(26/99)=74.77=74.8°
Answer:
∠ M ≈ 74.8°
Step-by-step explanation:
Using the cosine ratio in the right triangle
cos M = [tex]\frac{adjacent}{hypotenuse}[/tex] = [tex]\frac{OM}{MN}[/tex] = [tex]\frac{26}{99}[/tex] , then
∠ M = [tex]cos^{-1}[/tex] ([tex]\frac{26}{99}[/tex] ) ≈ 74.8° ( to the nearest tenth )
What is the exponential function (0,25) (1,50) (2,100) (3,200) (4,400)
Answer:
Step-by-step explanation:
If it is exponential dividing any term by the preceding term will be a constant, the common ratio or rate. 50/25=100/50...=2 The initial value, a, (at x=0) is 25 so the general form is
y=ar^x we have a=25 and r=2 so
y=25(2^x)
