Consecutive even integer word problem help please!!
Answer:
Width: 16 in., Length: 18 in.
Step-by-step explanation:
Consecute even/odd problems seem a bit weird at first.
You choose a variable to represent the first integer, say n . Assume it's even (no symbolic way to tell!). If n is even, then the next consecutive integer is n + 2. You add two because you want to skip one integer.
Width: n
Length: n + 2
Area is length multiplied by width, so
[tex]n(n+2)=224\\\\n^2+2n=224\\\\n^2+2n-224=0\\\\(n+14)(n-16)=0\\\\n+14=0 \text{ or } n-16=0\\\\n=-14 \text{ or }n=16[/tex]
The negative solution makes no sense, so use n = 16
Width: 16
Length: 18

Answer:
C. (4 , 3)
Step-by-step explanation:
We are given a system of equations and are asked to find its coordinate value.
To solve, we can keep in mind that both start with y, therefore meaning that we can replace one of the y's with one of the equations.:
[tex]y=\frac{1}{4}x+2\\y=x-1[/tex]
[tex]\frac{1}{4}x+2 = x-1[/tex]
Let's try to get x alone, first subtract 2 from both sides:
[tex]\frac{1}{4}x=x-3[/tex]
Now subtract x from both sides:
[tex]-\frac{3}{4}x=-3[/tex]
Now since the denominator is 4, multiply both sides by 4:
[tex]-3x=-12[/tex]
Lastly, divide both sides by -3 to get x :
[tex]x=4[/tex]
Now that we know x is 4, we can substitute 4 for x in both equations:
[tex]y=\frac{1}4(4)+2\\y=(4)-1[/tex]
[tex]y= 3\\y= 3[/tex]
Y is equal to 3, therfore, our coordinate value is C. (4,3)

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

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.

Define the formula for surface area of a cube.

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

The area of a rectangle is 81cm^2 what are the dimensions if the perimeter is minimum. What is the value of these minimum perimeter?
Answer:
The perimeter is 36 cm
Step-by-step explanation:
Given;
area of the rectangle, A = 81 cm²
let the Length, = L
let the breadth = b
Perimeter, P = 2L + 2b
Area, A = Lb = 81
[tex]L = \frac{81}{b} \\\\P = 2(\frac{81}{b} ) \ + \ 2b\\\\P = \frac{162}{b} \ + \ 2b\\\\P = 162(b^{-1}) \ + \ 2b\\\\minimize \ the \ perimeter \ to \ obtain \ the \ critical \ points;\\\\P' = -162 (b^{-2}) \ + \ 2\\\\P' = \frac{-162}{b^2} \ + \ 2\\\\P' = \frac{-162 \ + \ 2b^2}{b^2} \\\\at \ critical \ points; P' = 0\\\\\frac{-162 \ + \ 2b^2}{b^2} = 0\\\\-162 \ + \ 2b^2 = 0\\\\2b^2 = 162\\\\b^2 = 81\\\\b = +/- \ \sqrt{81} \\\\b = +/- \ \ 9\\\\[/tex]
[tex]since \ the \ breadth \ will \ be \ positive \ ; b = 9 \ cm[/tex]
L = 81/9
L = 9 cm
The perimeter = 2 (L + b)
= 2 (9 + 9)
= 2(18)
= 36 cm

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
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'll mark as brainliest if it lets me;-;

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.
[tex] radius \: \overline {OR} \perp chord \: \overline {AB} [/tex] at C. (given)
[tex] \therefore BC = AC[/tex] (perpendicular dropped from the center of the circle to the chord bisects the chord)
[tex] \therefore 7x-5=4x+10 [/tex]
[tex] \therefore 7x - 4x= 5 + 10[/tex]
[tex] \therefore 3x= 15[/tex]
[tex] \therefore x= \frac{15}{3}[/tex]
[tex] \therefore x= 5[/tex]
[tex] AC = 4x+10=4(5)+10=20+10= 30[/tex]
[tex] BC= 7x - 5=7(5)-5=35-5= 30[/tex]
AB = AC + BC = 30 + 30 = 60

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
