Answer:
≈ 7.73
Step-by-step explanation:
Area of a circle = π [tex]r^{2}[/tex]
Area of a rectangle = width x height
Circle:
π [tex]3^{2}[/tex] = π 9 ≈ 28.27 area of each circle
1/2 28.27 + 1/2 28.27 = 28.27 = area of the white region
Square:
6 x 6 = 36 = area of the square (green and white combined)
36 - 28.27 ≈ 7.73 (the whole square, minus the white area)
x+3/x-2 - 1-x/x =17/4
find the x with methods
Answer:
The solution set is {-2/9, 4).
Step-by-step explanation:
(x + 3)/(x-2) - (1-x)/x = 17/4
Multiply through by the LCD ( = 4x(x - 2):
(x + 3)4x - 4(1 - x)(x - 2) = 17x(x - 2)
4x^2 + 12x - 4(x - 2 - x^2 + 2x) - 17x^2 + 34x = 0
4x^2 + 12x - 4x + 8 + 4x^2 - 8x - 17x^2 + 34x = 0
-9x^2 + 34x + 8 = 0
We need 2 numbers whose product = -72 ( -9 * 8) and whose sum is 34.
These are +36 and -2, so we write:
-9x^2 + 36x - 2x + 8 = 0
-9x(x - 4) - 2(x - 4) = 0
(-9x + 2)(x - 4) = 0
x = -2/9, 4.

Step-by-step explanation:
The equation of a circle with radius [tex]r[/tex] and center [tex](h, k)[/tex] is given by:
[tex](x-h)^2+(y-k)^2=r^2[/tex]
From this, we can find that the radius of the circle is [tex]\sqrt{4}=2[/tex] and the center of the circle is at [tex](3, 5)[/tex]. Therefore, the coordinates of all points exactly 2 units away from this center point will lie on the circle.

Identity the slope and y intercept
Answer:
3,-2
Step-by-step explanation:
From the attached graph we need to find the slope and the y Intercept . The data that can beextracted from the graph is ,
The line passes through (0,3) and (1.5,0) .Hence the y Intercept here is 3 , since the graph cuts y axis at 3 units above the x axis.
Slope :-
→ m = 3 - 0 / 0 - 1.5
→ m = 3/-1.5
→ m = -2
• Hence the y Intercept is 3 and the slope is (-2) .Which equation can be used to find the volume of this solid? 6 in 8 in. 1 7 in. O V. 758 xa ov-+6+8 o v-7x6x8
Answer:
Option 1: V = pi(6)2(8)
Step-by-step explanation:
This is because when we plug in the value given in the picture.
Formula
The way we write this is by using our "r" which is 6. We plug in the 6 for "r" so the equation will look something like this:
Then we will plug in our height "h", which is 8. So the equation will look something like this:
So that's it. Very simple. Just remember to keep the formula in mind and you will get the hang of it.
I hope this help! :D
Equation to calculate volume of solid is V = 6 × 8 × 7
What is equation?An equation is a formula that expresses equality by connecting two expressions with an equal sign =. Equation consists of variables, constants and coefficients. Right side and left side of an equation are in equality.
There are different types of equations as linear equations, quadratic equation etc.
example: 2x + 5y + 7 = 0 is an equation
here, 2, 5 are coefficients of variables x and y, 7 is a constant value
2x² + 5x + 3 = 0 is a quadratic equation.
Given,
measurement of the sides of solid
length = 6in
Width = 8 in
Height = 7 in
Volume = Length×Width×Height
V = 6 × 8 × 7
Volume = 336 in³
Hence, V = 6 × 8 × 7 is the equation to calculate volume of solid.

What is the measure of angle A?

C.) 45 degrees
D.) 55 degrees
The measure of angle A.
Solution:-[tex]{\boxed{\mathcal{\red{B.\:Angle\: A \:=\: 40° \:}}}}[/tex]✅
Step-by-step explanation:-We know that,
[tex]\sf\pink{Sum\:of\:angles\:of\:a\:triangle\:=\:180°}[/tex]
➪ 90° + x + 51 + x + 41 = 180° ( 90° since it is a right-angled triangle )
➪ 2 x + 182° = 180°
➪ 2 x = 180° - 182°
➪ x = [tex] \frac{ - 2}{2} [/tex]
➪ x = -1°
Now,
Measure of angle A = x + 41
= (-1°) + 41
= 40°
[tex]\sf\red{Therefore, \:the\: measure\:of \:∠\: A\: is \:40°.}[/tex]
To verify:-90° + (-1°) + 41 + (-1°) + 51 = 180°
✒ 182°- 2°= 180°
✒ 180° = 180°

Xander has $15 and make $4 a day. Aislyn has $10 and makes $4 a day. When will they have the same amount of money?
Answer: Never because Aislyn cannot catch up if they make the same amount of money per day.
Step-by-step explanation:
Assume that the day they will have the same amount of money is x.
The amount that Xander will have on that day is:
= 15 + 4x
The amount that Aislyn will have on that day is:
= 10 + 4x
Equate the two fractions:
15 + 4x = 10 + 4x
15 - 10 + 4x = 4x
5 = 4x - 4x
5 = 0x
What this means is that they will never have the same amount of money because they are increasing by the same amount so Aislyn will never catch up.

The sun of two numbers is 17. One number is 3 less than 2/3 of the other number what is the lesser number?
A. 5
B. 3
C. 7
D. 12
Answer:
lesser # is 5
other # is 12
Step-by-step explanation:
x = lesser #
x + y = 17
x = 2/3y - 3
let 'y' = 17-x
substitute 'y':
x = 2/3(17-x) - 3
x = 34/3 - 2x/3 - 9/3
add 2x/3 to each side to get:
5x/3 = 25/3
multiply each side by 3/5 to get:
x = 25/5 or 5
5 + y = 17
y = 12

what is the geometric mean of 14 and 6
Answer:
8
Step-by-step explanation:
The geometric mean of two numbers 14 and 6 is 2√21.
What are arithmetic and geometric mean?An arithmetic mean can be obtained by taking the sum of all the numbers and dividing it by the number of numbers.
In the case of geometric mean, we multiply the numbers and raise them to the reciprocal of a total number of numbers.
Given, Two numbers 14 and 6.
Now, 14×6 = 84.
Now, we have to take the square root of 84 as we have two numbers.
Therefore, The geometric mean of 14 and 6 is,

Mezclas de alimentos. Un chef repostero creó una solución de azúcar de 50 onzas constituida por 34% de azúcar con una solución de azúcar al 20% y otra solución al 40%. ¿Qué cantidad utilizó de la solución de azúcar al 20% y de la solución al 40%?
Answer:
Las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.
Step-by-step explanation:
Podemos estimar la proporción de ingredientes mediante el siguiente promedio ponderado:
[tex]0.34= \frac{0.2\cdot m_{A} + 0.4\cdot m_{B}}{m_{A}+m_{B}}[/tex] (1)
Donde:
[tex]m_{A}[/tex] - Masa de la solución al 20 %, en onzas.
[tex]m_{B}[/tex] - Masa de la solución al 40 %, en onzas.
Podemos simplificar la formula como sigue:
[tex]0.2\cdot x + 0.4\cdot (1-x) = 0.34[/tex] (2)
Donde [tex]x[/tex] es la proporción de la solución al 20 % dentro de la solución final, sin unidades.
Ahora resolvemos para [tex]x[/tex] en (2):
[tex]0.4-0.2\cdot x = 0.34[/tex]
[tex]0.2\cdot x = 0.06[/tex]
[tex]x = \frac{0.06}{0.2}[/tex]
[tex]x = 0.3[/tex]
Este resultado quiere decir que la solución al 34 % es el resultado de 30 % de la solución al 20 % y 70 % de la solución al 40 %. Si conocemos que la solución final tiene una masa de 50 onzas, entonces las cantidades empleadas para su preparación son: 15 onzas de solución al 20 % y 35 onzas de solución al 40 %.
