Answer:
159 degrees
Step-by-step explanation:
A full semicircle (or half circle) has a degrees of 180. And x is equal that semicircle so x = 180, now if we subtract 21 from 180 we get 159, so X = 159.
5x + 7 = 2x - 8 can anyone say how to solve please
Answer:
x = - 5
Step-by-step explanation:
Given
5x + 7 = 2x - 8 ( subtract 2x from both sides )
3x + 7 = - 8 ( subtract 7 from both sides )
3x = - 15 ( divide both sides by 3 )
x = - 5

The length of a rectangle is 36
centmeters and the width is 9
centimeters. A similar rectangle has
a width of 3 centimeters.
what is
the length of the decond triangle?
Answer: 12cm
Step-by-step explanation:
They are similar, so we can set an equation of:
the ratio of length and width of the big triangle equal to the ratio of length and width of the small(second) triangle.
36:9 = x:3
36/9 = x/3
9x = 3(36) by use the cross multiply
9x = 108
x = 12 cm

Find the perimeter of the figure.
Answer:
87
Step-by-step explanation:
So there are 5 numbers listed. You can obviously see the two small sides are 9. They are the same size. Then you have the three 9s on the top. This is important. So far we are at 75ft. The complication comes in at what is the unknown side. Well if you see the three 9s on top. Two are going horizontal along with the 30. So 9+9 is 18. 30-18 is 12. So that side is 12. Answer is 87.
Hope this helps
Does this triangle have a hypotenuse about 38 feet long
Find the area of the composite shape below.
help to get sum coin
Answer:
Composite Area = 1105.94
Step-by-step explanation:
Remark
The two semi circles at each end make an entire circle with radius 11. The width of the central rectangle = the diameter of the circle. The area should be able to be found.
Width
2*radius = width
width = 2 * 11
width = 22
Area of the circle
Area = pi * r^2
r = 11
Area = 3.14 * 11^2
Area = 3.14 * 121
Area = 379.94
Area of the rectangle
Area = L * W
L = 33
W = 22
Area = 33 * 22
Area = 726
Total Area
Total Area = Area of Rectangle + Area of the Circle
Total Area = 726 + 379.94 = 1105.94
Why is (a+b)(a-b) = a2-b2
Answer:
see explanation
Step-by-step explanation:
(a + b)(a - b)
Each term in the second factor is multiplied by each term in the first factor, that is
a(a - b) + b(a - b) ← distribute parenthesis
= a² - ab + ab - b² ← collect like terms
= a² - b²
This is a standard algebraic identity, called the difference of squares

Diego and Jada are both trying to write an expression with fewer terms that is equivalent to
7a + 5b - 3a + 4b
Jada thinks 10a - 1b is equivalent Diego thinks 4a + 9b is equivalent
Answer: Diego, 4a + 9b is equivalent
Step-by-step explanation:
7a + 5b - 3a + 4b
= (7a - 3a) + (5b + 4b) We rerange the variables, and put them together with (), which make it more clear to solve.
= 4a + 9b

Averigua: Cuantos habitantes tiene tu localidad y cuantos tu provincia Calcula A qué porcentaje de la población del Ecuador con responder xf 13 puntos y responden esta pregunta porfa ❤❤❤❤❤❤❤✨
Answer:
La Provincia del Guayas comprime el 25.1% de la población de Ecuador. A su vez, la Ciudad de Guayaquil tiene una población igual al 15.58% de la población ecuatoriana.
Step-by-step explanation:
Dado que vivo en la Provincia del Guayas, y en la ciudad de Guayaquil, los datos de población solicitados son los siguientes:
-Provincia del Guayas: 4.387.434 habitantes, es decir, un 25.1% del total de la población de Ecuador, que es de 17.475.570 habitantes, conforme surge del siguiente calculo:
17.475.570 = 100
4.387.434 = X
4.387.434 x 100 / 17.475.570 = X
438.743.400 / 17.475.570 = X
25,10 = X
-Ciudad de Guayaquil: 2.723.665 habitantes, es decir, un 15.58% del total de la población de Ecuador, conforme surge del siguiente cálculo:
17.475.570 = 100
2.723.665 = X
2.723.665 x 100 / 17.475.570 = X
272.366.500 / 17.475.570 = X
15.58 = X

Answer:
1. $9.86
2. $531.51
3. $49.81
4. $6.03
5. $25.13
Step-by-step explanation:
1. 15% of 65.75 = 9.8625 about 9.86 (asks only for the amount for the tip)
2. 18% of 450.50 = 81.01
450.50 + 81.01 = $531.51(Asks for total; the price of the food including tip).
3. 25% of 39.85 = 9.9625
39.85 + 9.9625 = 49.8125 about 49.81 (asks for total; the price of the food including tip).
4. 12% of 50.25 = 6.03 (Asks only for the amount of the tip)
5. 20% of 125.67 = 25.13400 about 25.13 (Only asks the amount of the tip)

Find the solutions of the quadratic equation 3x^2 – 2x +4= 0.
Answer:
C. x =(1±i√11)/3
Step-by-step explanation:
Use the quadratic formula to find the solutions.
(−b±√b²−4(ac))/2a
Substitute the values a=3, b=−2, and c=4 into the quadratic formula and solve for x.
2±√(−2)²−4⋅(3⋅4)2⋅3
Simplify.
x=(1±i√11)3
