Answer:
S = 4a
Step-by-step explanation:
Rosa saves three times as much money as Anna. If a represents Anna's savings, which relationship shows how much money they have saved,
together?
Let
S = Total money they have saved,
together
a = Anna's savings
Rosa saves three times as much money as Anna
Rosa = 3 * a
= 3a
Total savings = Anna's savings + Rosa's savings
S = a + 3a
S = 4a

Answer:
If the angle is in radians...
Area of sector =½r²¢
Where ¢ is theta.
Since Our angle is degree
We use
Area of Sector = ¢/360 x πr²
¢=theta
radius = Diameter/2
radius = 16/2 = 8m
Area = 126/360 x π x 8²
= 112π/5
=70.37

-3c-11+14c=-14c-11
help me lol
Answer:
0
Step-by-step explanation:
-3c-11+14c=-14c-11
+14c
-3c-11+28c = -11
+11
-3c+28c = 0
25c=0
divide both sides by 25
c=0
Answer:
c=0
Step-by-step explanation:
-3c-11+14c=-14c-11
Combine like terms
-11c -11 = -14c -11
Add 11 to each side
-11c-11+11 = -14c -11+11
-11c = -14c
Add 14c to each side
-11c+14c = -14c+14c
3c =0
Divide by 3
3c/3 = 0/3
c =0

Surface Area
Answer:
107 in ²
Step-by-step explanation:
Surface area of the triangular prism = bh + L(s1 + s2 + s3)
Where,
b = 2 in.
h = 8 in.
s1 = 8.2 in.
s2 = 2 in.
s3 = 8 in.
L = 5 in.
Substitute
Surface area = 2 × 8 + 5(8.2 + 2 + 8)
Surface area = 16 + 5(18.2)
Surfaces area = 16 + 91
Surface area = 107 in ²
What is the inverse of the function f(x) = 2x + 1?
Answer:
[tex]f(x)^{-1}=\frac{x-1}{2}[/tex]
Step-by-step explanation:
start by replacing f(x) for y:
y = 2x + 1
switch y and x:
x = 2y+1
solve for x by first subtracting 1 from both sides:
2y = x-1
divide 2 from both sides:
y = [tex]\frac{x - 1}{2}[/tex]
replace y with [tex]f(x)^{-1}[/tex]:
[tex]f(x)^{-1}=\frac{x-1}{2}[/tex]

The function f(t)=5600(1.006)^{10t}f(t)=5600(1.006) 10t represents the change in a quantity over decades. What does the constant 1.006 reveal about the rate of change of the quantity?
Answer:
If [tex]r = 1.006[/tex], then it means that dependent variables increases by a factor of 1.006 per decade.
Step-by-step explanation:
Mathematically speaking, the function represents an exponential equation, whose form is:
[tex]f(t) = a_{o}\cdot r^{k\cdot t}[/tex] (1)
Where:
[tex]t[/tex] - Independent variable.
[tex]r(t)[/tex] - Dependent variable.
[tex]a_{o}[/tex] - Initial value.
[tex]k[/tex] - Convergence ratio.
[tex]r[/tex] - Increase rate.
If [tex]r = 1.006[/tex], then it means that dependent variables increases by a factor of 1.006 per decade.

Cylinder radius is 2 cm height is 10cm what is the surface area
Given:
Radius of a cylinder = 2 cm
Height of the cylinder = 10 cm
To find:
The surface area of the cylinder.
Solution:
The total surface area of the cylinder is:
[tex]A=2\pi rh+2\pi r^2[/tex]
Where, r is the radius and h is the height of the cylinder.
Putting [tex]r=2[/tex] and [tex]h=10[/tex] in the above formula, we get
[tex]A=2\pi (2)(10)+2\pi (2)^2[/tex]
[tex]A=40\pi +2\pi (4)[/tex]
[tex]A=40\pi +8\pi [/tex]
[tex]A=48\pi [/tex]
Therefore, the surface area of the cylinder is [tex]48\pi [/tex] square cm and its approximate value is 150.8 square cm.
Kumar bought some mangoes. The price of each mango () is found to be 6 more than the total number of mangoes bought by him and the total amount paid for all the mangoes is 280. Represent the situation mathematically and find the total number of mangoes bought by Kumar.
Answer:
Price = 20, Amount = 14
Step-by-step explanation:
A = Amount of Mangoes
P = Price for 1 Mango
P = A + 6
280 = P * A
insert A+6 for P
280 = (A+6) * A
280 = 6A + A²
280=1*a^2+6*a | Vertausche beide Seiten der Gleichung.
1*a^2+6*a=280 | quadratische Ergänzung: ergänze auf beiden Seiten (3)^2
1*a^2+6*a+(3)^2=3^2+280 | Rechne 3 hoch 2 aus.
1*a^2+6*a+(3)^2=9+280 | addiere 9 und 280
1*a^2+6*a+(3)^2=9+280 | Fasse die rechte Seite mit Hilfe der binomischen Formel zusammen.
1*(1*a+(3))^2=289 | Auf beiden Seiten Quadratwurzel ziehen.
1*a+(3)=+-*289^0.5
1*a_1+(3)=289^0.5
1*a_1+3=289^0.5 | Ziehe die Wurzel aus 289
1*a_1+3=17 | -3
1*a_1=14
The total number of mangoes bought by Kumar are 14.
What is mathematical equation?"An equation is a mathematical statement with an 'equal to' symbol between two expressions that have equal values is called mathematical equation. For example, 3x + 5 = 15. There are different types of equations like linear, quadratic, cubic, etc."
We have,
Total amount for mangoes(P) = 280
Price of one mango is equal to 6 more than the total number of mangoes (A) i.e., P = A+6
By using mathematical equation from the question
P×A = 280.....(1)
Substitute P = A+6 in equation (1)
⇒ (A+6) × A = 280
⇒[tex]A^{2}+6A =280[/tex]
Add [tex]3^{2}[/tex] on both sides of above equation
⇒[tex]A^{2}+6A+3^{2} = 280+3^{2}[/tex]
⇒[tex]A^{2}+2.(1)(3A)+3^{2} =289[/tex] (∵ [tex](a+b)^{2} = a^{2}+2ab+b^{2}[/tex])
⇒[tex](A+3)^{2} =289[/tex]
⇒[tex]A+3 = \sqrt{289}[/tex]
⇒[tex]A=17-3[/tex]
⇒[tex]A=14[/tex]
Hence, The total number of mangoes bought by Kumar are 14.

Helpppp does anyone know
======================================================
Explanation:
We can apply the remote interior angle theorem. Some math books or teachers may refer to this as the "exterior angle theorem". They're the same idea just with different names.
According to that theorem, the interior angles x and 53 add up to the exterior angle 158
x+53 = 158
x = 158-53
x = 105
This theorem only works if neither interior angle is adjacent to the exterior angle. Hence the "remote" part.
----------
If you wanted a slightly longer approach, then let y be the missing angle that isn't marked in the diagram. Angle y is adjacent to the 158 degree angle.
We can find y by noting how 158 and y are supplementary
158+y = 180
y = 180-158
y = 22
Then we use the fact that adding three angles of any triangle always gets us 180 degrees
x+y+53 = 180
x+22+53 = 180
x+75 = 180
x = 180-75
x = 105
Effectively, this example helps reinforce why the remote interior angle theorem is true.

Select the correct answer. Which graph represents the solution to this inequality? A. B. C .
Answer: C
Step-by-step-explanation: Given
- (12x + 8) ≤ - 2x + 11 ← distribute parenthesis on left side
- 3x - 2 ≤ - 2x + 11 ( add 3x to both sides )
- 2 ≤ x + 11 ( subtract 11 from both sides )
- 13 ≤ x , thus
x ≥ - 13
Since x can equal - 13 then a solid circle at - 13 represents the solution
Since x greater than - 13 then the arrow is facing to the right of - 13 on the number line.
Then the graph representing the solution is C

Question 3
Find the equation of the line joining (-2,4) and (3,7)
Answer:
y = (3/5)x+26/5 or 5y = 3x+26
Step-by-step explanation:
Applying,
The equation of a line in two point form
(y₂-y₁)/(x₂-x₁) = (y-y₁)/(x-x₁)............... Equation 1
From the question,
Given: y₂ = 7, y₁ = 4, x₂ = 3, x₁ = -2
Substitute these values into equation 1
(7-4)/[3-(-2)] = (y-4)/(x+2)
3/5 = (y-4)/(x+2)
5(y-4) = 3(x+2)
5y-20 = 3x+6
5y = 3x+6+20
5y = 3x+26
y = (3/5)x+26/5
Hence the equation of the line is y = (3/5)x+26/5 or 5y = 3x+26
