A painter uses 2 1/2 cans of paint 1/4 of a room. How much of a room could he paint with 1 can of paint?
Answer:
1/10
Step-by-step explanation:
First, convert your numbers to decimals.
2.5 cans of paint cover 0.25 area of a room.
Equation:
2.5=0.25
If you divide 2.5 by 5, you'll get 0.5.
But what you do to one side, you do it to the other.
0.25÷5= 0.05
So now you have your new equation
0.5=0.05
since you want 1 can of paint, multiply it by 2.
1= 0.1
convert it back to fraction: 1/10

Answer:
[tex]x^2+2x+1[/tex]
Step-by-step explanation:
When given the following expression,
[tex](x+1)(x+1)[/tex]
One must multiply every term in one of the parenthesis by every term in the other, thus, the resulting expression formed,
[tex](x)(x)+(1)(x)+(1)(x)+(1)(1)[/tex]
After distributing, simplify the expression, perform the multiplication and combine like terms,
[tex]x^2 + 2x + 1[/tex]

A circle with center O is shown. Create the equation for the circle.
Answer:
(5 - 1)^2 + (1 - 1)^2 = 4^2
Step-by-step explanation:
Circle equation: ( x - h )^2 + ( y - k )^2 = r^2
(h,K) is the coordinate of the center.
Center: (1,1)
(x,y) choose a point that could be the radius. (I choose the one on the top left side).
Point: (5,1)
Diameter: 8
Radius: 4
Plug in:
( x - h )^2 + ( y - k )^2 = r^2
(5 - 1)^2 + (1 - 1)^2 = 4^2 (or 16)
Solve to see if it's true,
(5 - 1)^2 + (1 - 1)^2 = 4^2 (or 16)
4^2 + 0^2 = 4^2
16 = 16 (This is true, therefore, the equation is correct).
Answer:(x-1)^2 + (y-1)^2=16

The concert tickets for Saturday were reduced from $50 to $30. By what percentage was the concert tickets reduced?
Answer:
40% price reduction
Step-by-step explanation:
The tickets were reduced by 40% because 20 is 2/5 or 40% of 50 and that was the amount of the price reduction.
Answer:
%40
Step-by-step explanation:
Here is why:
Because every dollar coutns as 2% of the price so 20 * 2 is 40 and you will get %40!

Find the number of distinct permutations of the letters in the word MATHEMATICS
Answer:
4989600
step by step explanation:
Step by step workout
step 1 Address the formula, input parameters and values
Formula:
nPr =n!
(n1! n2! . . . nk!)
Input Parameters & Values:
Total number of alphabets (n) & subsets (n1, n2, . . nk) in the word "MATHEMATICS"
n = 11
Subsets : M = 2; A = 2; T = 2; H = 1; E = 1; I = 1; C = 1; S = 1;
n1(M) = 2, n2(A) = 2, n3(T) = 2, n4(H) = 1, n5(E) = 1, n6(I) = 1, n7(C) = 1, n8(S) = 1
step 2 Apply the input parameter values in the nPr formula
=11!
(2! 2! 2! 1! 1! 1! 1! 1! )
=1 x 2 x 3 x 4 x 5 x 6 x 7 x 8 x 9 x 10 x 11
{(1 x 2) (1 x 2) (1 x 2) (1) (1) (1) (1) (1)}
=39916800
8
= 4989600
In 4989600 distinct ways, the letters of word "MATHEMATICS" can be arranged.
Name two triangles that are congruent by ASA.
Answer:
correct
Step-by-step explanation:
Angle-Side-Angle (ASA) Postulate:
If two angles and the included side of one triangle are congruent to two angles and the included side of another triangle, then the two triangles are congruent.
<C = <G
CA = GD
<A = <D
Triangle CAT = Triangle GDO are the two triangles that are congruent by the ASA Postulate.

In ΔIJK, the measure of ∠K=90°, IJ = 8.6 feet, and KI = 4.5 feet. Find the measure of ∠I to the nearest tenth of a degree.
Answer:
m∠I = 58.4°
Step-by-step explanation:
cos = adjacent side/hypotenuse
It is always helpful to have a picture. In your case KI is adjacent to ∠I and IJ is the hypotenuse.
So cos I = KI/IJ = 4.5/8.6
arccos (4.5/8.6) = m∠I
m∠I = 58.4°
It is necessary for you to memorize the definitions of the trig functions in order to do these types of problems. OK?
Brewsky's is a chain of micro-breweries. Managers are interested in the costs of the stores and believe that the costs can be explained in large part by the number of customers patronizing the stores. Monthly data regarding customer visits and costs for the preceding year for one of the stores have been entered into the regression analysis and the analysis is as follows: Average monthly customer visits 1,462 Average monthly total costs $ 4,629 Regression Results Intercept $ 1,496 b coefficient $ 2.08 R2 0.86814 What is the percent of the total variance that can be explained by the regression equation
Answer:
The answer is "88.9%"
Step-by-step explanation:
The Variance percentage indicates through the REgression equation but, the R-Square, it becoming the determination coefficient. 88.871% of the variance could be explained according to the above results.
3/5 of a number is 21 find the number
Answer:
35
Step-by-step explanation:
To find the original number multiply by the reciprocal of [tex]\frac{3}{5}[/tex] , that is
number = [tex]\frac{5}{3}[/tex] × 21 = [tex]\frac{105}{3}[/tex] = 35
A bag contains 6 red marbles, 4 blue marbles and 7 green marbles. If three marbles are drawn out of the bag, what is the probability, , that all three marbles drawn will be green?
Answer:
Step-by-step explanation:
Not large
Total number of marbles = 4 + 7 + 6 = 17
Number of green marbles = 7
Probability of first marble being green = 7/17
Probability of the second marble being green = 6/16
Probability of the third marble being green = 5/15
Probability (3 green) = 7 / 17 * 6/16 * 5/15 = 210 / 4080 = 0.05147

Step-by-step explanation:
find the amplitude of the function. y=1.5sin4x
Answer:
amplitude is 1.5
Step-by-step explanation:
If amplitude of f(x) is a, the amplitude of f(cx + d) is also a, for any d and non-zero c.
If amplitude of f(x) is a, the amplitude of cf(x) + d is c*a, for any d and any c.
From that we know that amplitude of y=1.5sin4x is the same as amplitude of y=1.5sinx, and 1.5 times more than amplitude of y=sinx. And we know that amplitude of sinx is 1.
Thus, amplitude of y=1.5sin4x is 1.5

Answer:
[tex]y=-\frac{1}{9}(x-2)^2-3[/tex]
Step-by-step explanation:
When a quadratic equation is in the form [tex]y=a(x-h)^2+k[/tex] (vertex form):
The x-coordinate can be found by identifying which value makes [tex](x-h)^2[/tex] equal 0The y-coordinate can be found by identifying the k value (y=k)Therefore, if the vertex of the function is at (2,-3), h needs to be 2 for [tex](x-h)^2[/tex] to equal 0 and k needs to be -3. The only equation that displays this is G:
[tex]y=-\frac{1}{9}(x-2)^2-3[/tex]
