A pack of clothes pins has 1 quarter yellow 2 thirds red and the rest blue how much blue pins are there
Answer: 1/12
Step-by-step explanation:
First make all the fractions have the same denominator. To do that, multiply the fractions by a number that will get them the same denominator. In this case, multiply 1/4 by 3, and 2/3 by 4.
1/4 x 3/3 = 3/12
2/3 x 4/4 = 8/12
then you have 3/12 + 8/12 = 11/12
so, blue is 1/12
Answer:
1/12 of the pins are blue
Step-by-step explanation:
¼ yellow & ⅔ red
First you have to find a common denominator.
4×3 =12 & 3×4 =12 so the common denominator is 12.
Now × the numerator on the fraction with the same number that you x the denominator and you will get 3/12 and 8/12.
3/12 +8/12 = 11/12
12/12 - 11/12 = 1/12
Therefor 1/12 of the pins are blue

HELPP(David saves 12 % of his monthly salary.
If he saves $17.75, what is his monthly
salary?)
Answer:
147.92
Step-by-step explanation:
Let the monthly salary be x
He saves 12 % and that is 17.75
x* 12% = 17.75
Change to decimal form
x *.12 = 17.17
Divide each side by .12
x*.12 /.12 = 17.75/.12
x =147.91666666
Rounding to the nearest cent
x = 147.92
Santiago buys a new computer for $3000. He pays it off in 2 years and pays $480 in simple interest. What was the interest rate?
Answer:
8%
Step-by-step explanation:
We can solve this by making use of the simple interest formula
I= PRT/100
480= 3000×R×2/100
480= 6000R/100
Cross multiply
48000= 6000R
R= 48000/6000
= 8%
Hence the rate is 8%

What is exponential regression?
Exponential regression refers to the process of arriving at an equation for the exponential curve that best fits a set of data.
What is the general form of the exponential regression equation?[tex]y =a b^{x}[/tex] is the general form of the exponential regression equation.
Let the exponential regression equation be [tex]y = ab^{x}[/tex].
Taking natural logarithm both the sides of [tex]y = ab^{x}[/tex]
⇒ [tex]ln y = a + x ln b..(i)[/tex]
For the value of a and b substitute the value of y and x from the given table.
substitute, y = 100 and x = 0 in equation (i)
⇒ [tex]ln100= a + 0[/tex]
⇒ a = 4.6
Substitute, y = 15, x = 1 and a = 4.6 in equation (i)
⇒ [tex]ln15 = 4.6 +( 1)lnb[/tex]
⇒[tex]2.7 - 4.6 = lnb[/tex]
⇒[tex]lnb = -1.9[/tex]
⇒ b = [tex]e^{-1.9}[/tex]
⇒ b = 0.149
⇒b = 14.9%
Hence, the value of b indicates 14.9% of the contaminants remains in water after each round of filters.

To do this, we make use of Euler's formula
[tex]F + V - E = 2[/tex]
Where
[tex]F \to Faces; V \to Vertices; E \to Edges[/tex]
[tex](a):\ Faces = 8; Vertices = 12; Edges = 6[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]8 + 12 - 6 = 2[/tex]
[tex]14 = 2[/tex]
The above equality is false. Hence, (a) does not exist
[tex](b):\ Faces = 6; Vertices = 6; Edges = 4[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]6 + 6 - 4 = 2[/tex]
[tex]8 = 2[/tex]
The above equality is false. Hence, (b) does not exist
[tex](c):\ Faces = 20; Vertices = 30; Edges = 12[/tex]
Using: [tex]F + V - E = 2[/tex]
[tex]20 + 30 - 12 = 2[/tex]

40) A 10 ft. ladder positioned against a house makes a 65 degree angle with the ground. How far away
from the house is the base of the ladder?
A. 4 feet
B. 6 feet
C. 9.06 feet
D. 4.22 feet
Answer:
Distance of ladder from base = 4.22 feet (Approx.)
Step-by-step explanation:
Given:
Length of ladder = 10 feet
Angle with ground = 65°
Find:
Distance of ladder from base
Computation:
Length of ladder (hypotenuse) = 10 feet
Distance of ladder from base (Base)
Using trigonometry function
Cosθ = Base / Hypotenuse
Cosθ = Distance of ladder from base / Length of ladder
Cos65 = Distance of ladder from base / 10
0.4226 = Distance of ladder from base / 10
Distance of ladder from base = 0.4226 x 10
Distance of ladder from base = 4.226
Distance of ladder from base = 4.22 feet (Approx.)
