Answer:
32% goes to 30%. 22% goes to 20%. 74% goes to 70%. 51% goes to 1/2.
Step-by-step explanation:
Just treat is as rounding. When you round, 32 goes to 30 because the 2 is 4 or less. 22 and 74 each respectively round to 20 and 70. 1/2 is equal to 50%. And 51% rounds to 50%, or 1/2.
The correct value of the percent on the left with the appropriate estimate on the right is,
32% - 30%
22% - 20%
74% - 70%
51% - 1/2
What is mean by Percentage?A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.
To Calculate the percent of a number , divide the number by whole number and multiply by 100.
Given that;
To match the percent on the left with the appropriate estimate on the right.
Now, We can simplify as;
32% = 0.32
22% = 0.22
74% = 0.74
51% = 0.51
20% = 0.20
70% = 0.70
1/2 = 0.5
30% = 0.3
Thus, The correct value of the percent on the left with the appropriate estimate on the right is,
32% - 30%
22% - 20%
74% - 70%
51% - 1/2

A scientist determines that the number of bacteria in a culture is modeled by the formula A(t)=4,000e0.02t, where t is the number of minutes after observation begins.
Using the exponential model given, the number of bacteria in the culture after 9 minutes after the observation began will be 4789
Given the exponential model :
[tex] A(t) = 4000e^{0.02t} [/tex] [tex] A(t) = Number\:bacteria\:in\:the\:culture\:after\:t\:minutes [/tex] t = number of minutes after observation beginsThe number of bacteria in the culture 9 minutes after the observation began can be calculated thus :
[tex]t = 9 \: minutes [/tex]
Substitute 9 for t in the exponential equation :
[tex] A(t) = 4000e^{0.02\times9} [/tex]
[tex] A(t) = 4000e^{0.18} [/tex]
[tex] A(t) = 4000 \times 1.1972173 [/tex]
[tex] A(t) = 4788.87 [/tex]
Therefore, the number of bacteria in the culture after 9 minutes will be about 4789

Solve v times w squared+ y= x. Solve for w. Please show me how you got the answer!
[tex]▪▪▪▪▪▪▪▪▪▪▪▪▪ {\huge\mathfrak{Answer}}▪▪▪▪▪▪▪▪▪▪▪▪▪▪[/tex]
let's solve for " w "
[tex]vw {}^{2} + y = x[/tex][tex]vw {}^{2} = x - y[/tex][tex] {w}^{2} = \dfrac{x - y}{v} [/tex][tex]w = \sqrt{ \dfrac{x - y}{v} } [/tex]Answer:
w = √( x - y ) / v
Step-by-step explanation:
in this situation, we are actually asked to make w the subject of the formula
this !means that we should make w be equal to every other variable meaning;
w = y + x
note that this is just an example
so, let us get started
we have;
vw² + y = x
first of all we have to move the y to the right hand side
it is more like collecting like terms so that at the end of the day we only end up with w on that side
vw² = x - y
now, we have to remove the ²
we will do that by square rooting both sides
√( vw )² = √( x - y )
the square root will remove the square because they are opposites of each other.
it is more like a multiplication sign canceling a division sign or when we bring a subtraction sign to the other side of the equation and it turns to an addition sign.
in our case, it is like bringing the square to the other side of the equation and it turns to a square root sign
so,
vw = √( x- y )
we ate almost done.
it is now time to remove the v by dividing through by v
this means that we remove the multiplication sign bonding the v and w through division just like the square root removing the square
vw / v = √( x - y ) / v
w = √( x - y ) / v
therefore , our answer is
w = √( x - y ) / v

Step-by-step explanation:
Actually, the function g(x) is irrelevant here. We need only evaluate the function f(x) = 3x + 1 at x = -2:
f(-2) = 3(-2) + 1 = -6 + 1 = -5

Answer:
x = 15.9
Step-by-step explanation:
Since this is a right triangle, we can use the Pythagorean theorem
a^2 + b^2 = c^2 where a and b are the legs and c is the hypotenuse
6^2 + x^2 = 17^2
36+ x^2 = 289
x^2 = 289-36
x^2 =253
Take the square root of each side
sqrt(x^2) = sqrt( 253)
x = 15.90597
Rounding to the nearest tenth
x = 15.9

Since all sides are equal length, the angles must be equal also.
All angles must be 60 degress and 60+60+60 =180
Answer:
60 degrees for all sides
Step-by-step explanation:
all equal and 60+ 60+ 60= 180

Answer:
[tex]y = \frac{4}{5} x - \frac{22}{5} [/tex]
Step-by-step explanation:
[tex]y = mx + b[/tex]
[tex] - 2 = \frac{4}{5} (3) + b \\ - 2 = \frac{12}{5} + b \\ - 2 - \frac{12}{5} = b \\ - \frac{10}{5} - \frac{12}{5} = b \\ - \frac{22}{5} = b[/tex]
Therefore, the equation of the line that goes through point (3, -2)and has slope ⅘ is
[tex]y = \frac{4}{5} x - \frac{22}{5} [/tex]

What's the slope of (6, 5) and (3, 7.5) ?
Answer:
The slope of (6, 5) and (3, 7.5) is 5/-6.
As a decimal: (-0.83333333333...)
Step-by-step explanation:
Formula for slope:
[tex]m=\frac{y^2-y^1}{x^2-x^1}[/tex]
('m' means slope.)
[tex](x^1,y^1) =[/tex] coordinates of the first coordinate point
[tex](x^2,y^2)=[/tex] coordinates of the second coordinate point.
--------------------------
Coordinates:
[tex](6,5)(3,7.5)[/tex]
-------------------------
Now, I will simply plug the numbers into the formula.
[tex]m=\frac{7.5-5}{3-6} =\frac{2.5}{-3} =5/-6[/tex]
As a decimal: (-0.83333333333...)
The slope of the given points is 0.833
Slope, m, is given by the formula
[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
From the question
[tex]x_{1} = 6[/tex]
[tex]y_{1} = 5[/tex]
[tex]x_{2}=3[/tex]
[tex]y_{2}=7.5[/tex]
Putting the above parameters into the formula
[tex]m = \frac{y_{2} -y_{1} }{x_{2} -x_{1} }[/tex]
We get
[tex]m =\frac{7.5-5}{3-6}[/tex]
∴ [tex]m= \frac{2.5}{-3}[/tex]
[tex]m = 0.833[/tex]
Hence, the slope of the given points is 0.833
