What percent of 700 is 14 ?
Answer:
2%
Step-by-step explanation:
We are to find out what percentage of 700 is 14.
Assuming [tex] x [/tex] to be the percent of 700 which is 14, we can write it as:
[tex] \frac { x } { 100 } \times 700 = 14 [/tex]
[tex] \frac { x } {100} = \frac {14} {700} [/tex]
[tex] \frac { x } { 1 0 0 } = 0.02 [/tex]
[tex]x=0.02 \times 100[/tex]
[tex]x=2[/tex]
Therefore, 14 is 2% of 700.

A bag contains 14 gray, 7 black and 10 white marbles. A marble is drawn at random. What is the theoretical probability, as a decimal, of drawing a black marble? Round the decimal to the nearest hundredth.
14 + 7 + 10 = 31 marbles total
7/31 = 0.23 or 23%
The probability of drawing a black marble from a bag containing 14 gray, 7 black, and 10 white marbles is 7/31, which, as a decimal rounded to the nearest hundredth, is 0.23.
The theoretical probability of drawing a black marble from a bag containing 14 gray, 7 black, and 10 white marbles can be calculated by dividing the number of black marbles by the total number of marbles in the bag.
To find the total number of marbles, we add up the counts for each color: 14 gray + 7 black + 10 white = 31 marbles in total.
Next, we calculate the probability by taking the number of black marbles and dividing it by the total number of marbles: Probability = (Number of black marbles) / (Total number of marbles) = 7 / 31.
Converting that probability into a decimal gives us approximately 0.2258. However, rounding this to the nearest hundredth, as asked in the question, gives us 0.23. So, the probability of drawing a black marble is 0.23.
What is the measure of each interior angle of a regular polygon with 5 sides?
ANSWER
108°
EXPLANATION
The measure of each interior angle of a regular polygon is given by
[tex] \theta = \frac{(n - 2) \times 180}{n} [/tex]
where n refers to the number of sides of the polygon.
From the question we have n=5 in this case.
We substitute to obtain;
[tex]\theta = \frac{(5 - 2) \times 180}{5} [/tex]
[tex]\theta = \frac{3\times 36}{1} [/tex]
This simplifies to:
[tex]\theta = 108 \degree[/tex]
Hence each interior angles of a regular polygon with 5 - sides is 108°

Sixteen is the same as one and two-tenths times a number added to negative 8.
Answer:
of the number is X, 16 = 1 + (2/10)×X - 8
Answer:
16 = [tex]\frac{6x}{5}[/tex] - 8
Step-by-step explanation:
Topic: One Unkown equation, mixed numbers
first we have to establish our variables, we only have one so we call
x = "a number"
and we start building our one unknown equation part by part by reading
"Sixteen is the same" means in math that "x ="
"one and two tenths" 1 [tex]^{2/10}[/tex]
this means we have (remember how to sum fractions?)
1 + 2 / 10 = 10/10 + 2/10 = 12/10 = 6/5
so " one and two tenths times a number added to negative 8" become [tex]\frac{6x}{5}[/tex] + (-8)
so we have our equation
16 = [tex]\frac{6x}{5}[/tex] + (-8) or 16 = [tex]\frac{6x}{5}[/tex] - 8

[tex]m=-\frac{5}{2}[/tex]
[tex]-\frac{5}{4}+m=-\frac{15}{4}[/tex]
[tex]m+2=-0.5[/tex]
Step-by-step explanation:
Given equation,
[tex]\frac{3}{4}+m=-\frac{7}{4}[/tex]
[tex]\implies m = -\frac{7}{4}-\frac{3}{4}=\frac{-7-3}{4}=-\frac{10}{4}=-\frac{5}{2}[/tex],
Since, [tex]\frac{10}{4}\neq -\frac{5}{2}[/tex]
[tex]\frac{11}{4}+m = -\frac{1}{4}[/tex]
[tex]\implies m = -\frac{1}{4}-\frac{11}{4}=\frac{-1-11}{4}=-\frac{12}{4}=-3\neq -\frac{5}{2}[/tex]
[tex]-\frac{5}{4}+m=-\frac{15}{4}\implies m = -\frac{15}{4}+\frac{5}{4}=\frac{-15+5}{4}=-\frac{10}{4}[/tex]
[tex]m+2=-0.5\implies m = -0.5-2\implies m = -2.5=-\frac{5}{2}[/tex]

Answer:
We can see here that the two sides of both triangle are equal to each other, therefore both triangles are isosceles triangles.
And also the two chords are parallel to each other, which let us know that:
b° = 40°
We also proved that that triangle is an isosceles triangle so:
b° = c° = 40°
Which makes it possible to calculate d°:
b° + c° + d° = 180°
40° + 40° + d° = 180°
d° = 180° - 40° - 40°
d° = 100°

4x=-4r+2d for x. Mary
Final answer:
To solve the equation 4x = -4r + 2d for x, isolate x by performing the same mathematical operations on both sides of the equation.
Explanation:
To solve the equation 4x = -4r + 2d for x, we need to isolate x on one side of the equation. We can do this by performing the same mathematical operations on both sides of the equation. Let's start by moving the terms containing r and d to the other side:
4x + 4r - 2d = 0
Next, we can factor out the common factor of 4:
4(x + r - 0.5d) = 0
Finally, we divide both sides of the equation by 4 to solve for x:
x + r - 0.5d = 0
The solution for x is x = -r + 0.5d.
F(x)=square root of x^2+24x+144. g(x) = square root of x^3 -216
The square root of f(x) is ±(x + 12) and the square root of g(x) is not defined.
What is function?In mathematics, a function is an expression, rule, or law that describes the relationship between one variable (the independent variable) and another variable (the dependent variable).
f(x) = x^2 + 24x + 144
f(x) = x^2 + 2(12)x + 12^2
f(x) = (x + 12)^2
Square root of f(x) is ±(x + 12)
g(x) = x^3 - 216
g(x) = (x - 6)(x^2 + 6x + 36)
Here, (x^2 + 6x + 36) does not have real roots hence it is not possible to find the square root of g(x).

Find the missing value for the exponential function represented by the table below x -2 -1 0 1 2 y 29 20.3 14.21 6.9629
To find the missing value, divide two consecutive y-values to determine the constant factor. Multiply the last given value by the factor to obtain the missing value.
Explanation:To find the missing value for the exponential function represented by the given table, we need to observe the pattern of the function.
The given pattern is:
x -2 -1 0 1 2
y 29 20.3 14.21 6.9629
In this case, we can see that each value of y is obtained by multiplying the previous value by a constant factor.
To determine this factor, we can divide any two consecutive y-values.
For example, dividing 14.21 by 20.3 gives us approximately 0.6988.
So, the missing value can be found by multiplying the last given y-value (6.9629) by this factor.
Hence, the missing value is approximately 4.8616.
