What shapes do I need to use to find the surface area? (How many of each shape)
Answer:
Area of Plane Shapes-
1. Triangle Area = ½ × b × h b = base h = vertical height
2. Square Area = a2 a = length of side
Step-by-step explanation:
The surface area of a solid object is a measure of the total area that the surface of the object occupies. The mathematical definition of surface area in the presence of curved surfaces is considerably more involved than the definition of arc length of one-dimensional curves, or of the surface area for polyhedra (i.e., objects with flat polygonal faces), for which the surface area is the sum of the areas of its faces. Smooth surfaces, such as a sphere, are assigned surface area using their representation as parametric surfaces. This definition of surface area is based on methods of infinitesimal calculus and involves partial derivatives and double integration. Surface area is the total amount of space that all of the surfaces of an object take up. It is the sum of the area of all the surfaces of that object.[1] Finding the surface area of a three-dimensional shape is moderately easy as long as you know the correct formula. Each shape has its own separate formula, so you'll first need to identify the shape you’re working with. Memorizing the surface area formula for various objects can make calculations easier in the future. Here are a few of the most common shapes you might encounter.
1
Define the formula for surface area of a cube.
2
Measure the length of one side.
3
Square your measurement for a.
4
Multiply this product by six.
An Angle measures 64 more than the measure of its supplementary angle what is the measure of each angle
Answer:
Original angle = 122*
Supplementary angle = 58*
Step-by-step explanation:
A supplementary angle is one of two angles that make up 180*
If one angle is 30*, its supplementary angle is 150*. 30 + 150 = 180.
So in this case we have two angles, the original and the supplementary angle. The original angle is 64* more than the supplementary angle. The key word is MORE.
The formula to figure it out would look like this: x + (x + 64) = 180
x is the supplementary angle
x + 64 is the original angle (64 MORE than its supplementary angle)
180 is the total measure of the two angles because they are supplementary and we know that supplementary angles always equals 180* when added together.
Take the formula and do a little algebra.
x + (x + 64) = 180
Subtract 64 from both sides
x + x = 116
Combine the x's
2x = 116
Divide both side by 2
x = 58
Remeber we know that the original angle is 64 more than the supplementary angle, so we'll add the 64 to the value of x and we get 122.
x + 64 = 122
Check our work:
x + (x + 64) = 180
58 + 58 + 64 = 180
Given :
An angle which measures 64° more the measure of its supplementary angle.⠀
To Find :
The measure of its supplementary angle.⠀
Solution :
Let's assume the one of the supplementary angle as x and the other angle as (x + 64)° .Now,
⠀
According to the Question :
⠀
[tex]\longrightarrow\qquad \sf{{x + (x + 64) {}^{ \circ} = {180}^{ \circ} }}[/tex]
⠀
[tex]\longrightarrow\qquad \sf{{x + x + 64 {}^{ \circ} = {180}^{ \circ} }}[/tex]
⠀
[tex]\longrightarrow\qquad \sf{{2x + 64 {}^{ \circ} = {180}^{ \circ} }}[/tex]
⠀
[tex]\longrightarrow\qquad \sf{{2x = {180}^{ \circ} - 64 {}^{ \circ}}}[/tex]
⠀
[tex]\longrightarrow\qquad \sf{{2x = {116}^{ \circ} }}[/tex]
⠀
[tex]\longrightarrow\qquad \sf{{x = \dfrac{{116}^{ \circ}}{2} }}[/tex]
⠀
[tex]\longrightarrow\qquad \mathfrak{\pmb{{x = {58}^{ \circ} }}}[/tex]
⠀
Therefore,
One angle = 58°Other angle = 58° + 64° = 122°⠀
Henceforth ,
The measure of the two angles are 122° and 58° .I need help with this
Answer:
D.
Step-by-step explanation:
You pass 3x to the other side so you get 4y = -16 - 3x
to clear y you divide both sides by 4
y = (-16-3x )/ 4
you can simplify this so it so it gives us
y = -4 - 3/4x

Which expression is not equal to the expression shown?
3³ ÷ 3⁻⁴
____________________Solution :-Given Information :-Equation 1 ( question )➢ 3³ ÷ 3⁻⁴Equation 2 ( option 1 )➢ 3⁻³ ÷ 3⁴Equation 3 ( option 2 )➢ 3 × 3⁶Equation 4 ( option 3 )➢ 3⁷ ÷ 3⁰Equation 5 ( option 4 )➢ 3³ × 3⁴To Find :-Which expression is not equal to the expression shown. Calculation :-Let's first solve all the equations and then check which equation is not equal to equation given in question.
Solving Equation 1 ( question ) :-⇒ 3³ ÷ 3⁻⁴ = 3³⁻⁽⁻⁴⁾
⇒ 3³⁺⁴ = 3⁷ = 2,187
Solving Equation 2 ( option 1 ) :-⇒ 3⁻³ ÷ 3⁴ = 3⁻³⁻⁴
⇒ 3⁻⁷ = 0.000457
Solving Equation 3 ( option 2 ) :-⇒ 3 × 3⁶ = 3⁷
⇒ 3⁷ = 2,187
Solving Equation 4 ( option 3 ) :-⇒ 3⁷ ÷ 3⁰ = 3⁷ ÷ 1
⇒ 3⁷ ÷ 1 = 2,187
Solving Equation 5 ( option 4 ) :-⇒ 3³ × 3⁴ = 3³⁺⁴
⇒ 3⁷ = 2,187
From the calculation of above equations, We have found that only Equation 2 ( option 1 ) 3⁻³ ÷ 3⁴ is not equal to Equation 1 ( question ) 3³ ÷ 3⁻⁴
Therefore, 3⁻³ ÷ 3⁴ ≠ 3³ ÷ 3⁻⁴
Hence, Option 1 is the correct answer.
____________________Final Answer :-Option 1 ) ⟶ 3⁻³ ÷ 3⁴ is the correct answer. ____________________

The graph below can be used to solve which equation?
Answer:
Ix + 2I - 5 = -(x - 1)*(x - 3)
Step-by-step explanation:
In the graph, we can see two functions a red one, f(x), and a blue one, g(x)
And the equation would be f(x) = g(x)
The red one is an absolute value function, we can see that the vertex is at x = -2 and at y = -5, and it has a slope equal to 1.
Remember that for an absolute value equation with a vertex (a, b) is:
f(x) = Ix - aI + b
Then in this case, the absolute value equation is:
f(x) = Ix - (-2)I - 5
f(x) = Ix + 2I - 5
The blue equation is a quadratic equation, with roots 1 and 3, and we can see that it opens down, so the leading coefficient is negative.
Remember that for a quadratic equation with roots a and b, with leading coefficient A is:
g(x) = A*(x - a)*(x - b)
Then in this case the quadratic equation is something like:
g(x) = -N*(x - 1)*(x - 3)
Then the equation will be something like:
f(x) = Ix + 2I - 5 = g(x) = -N*(x - 1)*(x - 3)
Ix + 2I - 5 = -N*(x - 1)*(x - 3)
The only option that has this shape is the first option (the top one) such that N = 1, then:
Ix + 2I - 5 = -(x - 1)*(x - 3)
is the correct option.
5.3x - 9 + 7.6x simplify pls
Answer:
12.9x-9
Step-by-step explanation:
add 5.3x and 7.6x
Answer:
12.9x-9
Step-by-step explanation:
First you have to combine the like terms which are 5.3x + 7.6x= 12.9x. Then you just rewrite the equation 12.9x-9. You just leave the 9 by it self because there's no other like terms.
More examples -
5.3x+−9+7.6x
Combine Like Terms:
=5.3x+−9+7.6x
=(5.3x+7.6x)+(−9)
=12.9x+−
One angle of an isosceles triangle measures 138°. Which other angles could be in that isosceles triangle?
Answer:
2 21 degree angles
Step-by-step explanation:
An isosoles triangle has two congruent angles and every triangle's sum of interior angles equals 180 degrees. 138*2>180, so the 138 degree angle cannot be congruent to any of the other angles. Therefore:
180=138+2x
42=2x
21 degrees=x
Use the figure below to find the value of x and y.
x = 4, y = √12
x = 4, y = 8
x = 4√3, y = √6
x = 4√6, y = 8√3
Answer:
Step-by-step explanation:
from the pic
cos(30deg) = 4√3 / y = √3 / 2
y = 4 * 2 = 8
sin(30deg) = x/y = 1/2
x = y/2 = 8/2 = 4
ans is x = 4, y = 8
Answer:
Step-by-step explanation:
As the given triangle is a right-angled triangle,
tan(30degree) = x / (4√3) = 1/√3
x = 4
sin(30degree) = x / y = 1/2
y = 8
make b the subject of the formula a=\sqrt(b+6)
Making 'b' the subject of formula gives b = a² - 6
How to determine the subject of formulaIt is important to note that the subject of formula is described as a variable that is made up to stand alone in an equation.
The subject of formula is the variable that is worked out on on side of the equation sign.
From the information given, we have the equation;
a = [tex]\sqrt{(b + 6)}[/tex]
To make 'b' the subject of formula, we take the following steps;
Find the square of both sides, we get;
a² = [tex](\sqrt{(b + 6)} ^2[/tex]
Cancel out the square, we get;
b + 6 = a²
collect the other terms on one end of the equation, we have;
b = a² - 6
Hence, the equation is b = a² - 6

Answer:
B. AC = 22, BC = 22, AB = 44
C. AC = 30, BC = 30, AB = 60
Step-by-step explanation:
B.
[tex] radius \: \overline {OR} \perp chord \: \overline {AB} [/tex] at C. (given)
[tex] \therefore AC = BC[/tex] (perpendicular dropped from the center of the circle to the chord bisects the chord)
[tex] \therefore 2x - 6 = x + 8[/tex]
[tex] \therefore 2x - x= 6 + 8[/tex]
[tex] \therefore x= 14[/tex]
[tex] AC = 2x-6=2(14)-6=28-6= 22[/tex]
[tex] BC= x + 8=14 + 8= 22[/tex]
AB = AC + BC = 22 + 22 = 44
C.
