Answer:
x = 7
Step-by-step explanation:
Given:
∠DEF = 117°
∠DEG = (12x + 1)°
∠GEF = (5x - 3)°
Find:
value of x
Computation:
∠DEF = ∠DEG + ∠GEF
117° = (12x + 1)° + (5x - 3)°
117° = 17 x - 2
x = 7
Answer:
7
Step-by-step explanation:
(12x + 1) + (5x - 3) = 117
17x - 2 = 117 Combine like terms
17x = 119 Add 2 to both sides
x = 7 Divide both sides by 17
What is the volume of a sphere with a radius of 5.9 inch rounded to the nearest 10th of a cubic inch
Answer:
860.3
Step-by-step explanation:
43·π·5.93≈860.28954in³
860.28954 = 860.3
The volume of the sphere is V = 859.9 inches³
What is a Sphere?A sphere is symmetrical, round in shape. It is a three dimensional solid, that has all its surface points at equal distances from the center. It has surface area and volume based on its radius. It does not have any faces, corners or edges.
The Surface Area of a Sphere = 4πr²
The Volume of a Sphere = ( 4/3 ) πr³
where r is the radius of the sphere
Given data ,
Let the radius of the sphere be r = 5.9 inches
Now , Volume of a Sphere = ( 4/3 ) πr³
On simplifying , we get
V = ( 4/3 ) ( 3.14 ) ( 5.9 )³
V = 859.853 inches³
Hence , the sphere has volume of 859.9 inches³

Evaluate the following
expression using x = 5:
3(3x + 5)
[tex] \huge\color{skyblue}\boxed{\colorbox{black}{Answer ☘}}[/tex]
Let's substitute x with 5 to find the value of given expression ~
[tex] \sf3[(3 \times 5) + 5][/tex][tex] \sf3(15 + 5)[/tex][tex] \sf3(20)[/tex][tex] \sf60[/tex]The value of the expression is 60.
What is the value of the expression?
According to the BODMAS rule, when there is a mathematical expression with a bracket, the terms in the bracket should be solved first. So the value of the expression in the bracket would be solved first.
(3(5) + 5)
(15 + 5)
= 20
The second step is to multiply 20 by 3.
20 x 3 = 60

Eq 1 X+Y=16
Eq 2 6x+9y=120
Solve by substitution
Solve step by step
Answer:
X = 8, Y = 8
Step-by-step explanation:
Step 1) Solve for Y w/ bottom equation to yield - y = -2/3x + 40/3.
Step 2) substitute equation into x + y = 16 to get 1/3x + 40/3 = 16 multiply by 3 to clear the fractions and get x + 40 = 48 - subtract 40 by both sides to get x = 8.
Step 3) Plug x = 8 into the bottom equation to get 48 + 9y = 120, subtract 48 by both sides to get 9y = 72 and then divide by 9. The product is y = 8.

find the value of x²+y² if
x+y=9 xy=14
Step-by-step explanation:
It's a system of equations.
From the first one we isolate x:
x = 9-y
And we substitute in the second one:
(9-y)y = 14
-y^2 + 9y - 14 = 0
y^2 - 9y + 14 = 0
D = 25
y1/2 = (9 +- 5)/2 = 2 or 7
y = 2 => x = 7
y = 7 => x = 2
x^2 + y^2 = 7^2 + 2^2 = 53
