Explanation:
Use of a calculator will show that
2/3 = 0.6666...
where the 6's go on forever. Your teacher only wants 2 significant figures though. That means you'll round to the nearest hundredth to get 0.67
The 0 to the left of the decimal point is not a significant figure. The reason being is because we can rewrite 0.67 into 6.7*10^(-1); we can see the coefficient 6.7 having two sig figs.

Solve the simultaneous equation 4x + 3y = -2 8x + 3y = 14
Answer:
x = 4 and y = -6
Step-by-step explanation:
Solve by elimination by multiplying the first equation by -2:
-8x - 6y = 4
8x + 3y = 14
Add them together and solve for y:
-3y = 18
y = -6
Plug in -6 as y into one of the equations and solve for x:
8x + 3y = 14
8x + 3(-6) = 14
8x - 18 = 14
8x = 32
x = 4
So, the solution is x = 4 and y = -6
Answer:
x = 4
y = -6
Step-by-step explanation:
4x + 3y = -2
8x + 3y = 14
Multiply the second equation by -1
4x + 3y = -2
-8x - 3y = -14
--------------------------
-4x = -16
Divide by -4
-4x/-4 = -16/-4
x = 4
4x+3y = -2
4*4 +3y = -2
16 +3y = -2
3y = -2-16
3y = -18
y = -6
Find the sum of the first 41 terms of the following series, to the nearest integer. 4, 12,20,...
Answer:
Sum of the first 41 terms = 6724
Step-by-step explanation:
[tex]a_{41} = a_1 + (n - 1 )d = 4 + (41 - 1) \times 8= 4 + 40 \times 8 = 324\\\\S_n = \frac{n}{2}(a_1 + a_n)\\\\s_{41} = \frac{41}{2} (4 + 324) = \frac{41}{2} \times 328 = 41 \times 164 = 6724[/tex]
The sum of the first 41 terms of the following series, to the nearest integer, is 6724.
What is an arithmetic sequence?A series of integers called an arithmetic progression or arithmetic sequence (AP) has a constant difference between the terms.
Given:
An arithmetic sequence,
4, 12,20,...
The common difference d,
d = 20 - 12 = 8.
To find the sum of the first 41 terms:
We will find the 41st term.
Remember that,
aₙ= a₁ + (n-1)d
a₄₁ = 4 + (40)8
= 324
The sum of the first 41 terms,
Sₙ = (41/2)(4 + 324) = 6724.
Therefore, the sum is 6724.

Answer:
[tex]x^{\circ}+105^{\circ}=180^{\circ},\\x^{\circ}=z^{\circ},\\180^{\circ}-z^{\circ}=y^{\circ}[/tex]
Step-by-step explanation:
Statement 1:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 2:
True - These two angles are vertical angles (opposite to each other at intersection of two lines). All vertical angles are equal.
Statement 3:
False - These two angles are vertical and therefore are equal. Thus, they cannot have a difference of 105.
Statement 4:
False - Two of these angles form one side of a line which is equal to 180 degrees. Since the third angle is greater than zero, they cannot all add up to 180 degrees.
Statement 5:
True - These two angles are supplementary (add up to 180 degrees) because they form one side of a line.
Statement 6:
False - These two angles are supplementary (add up to 180 degrees) because they form one side of a line and therefore cannot be equal to 105.
Answer and Step-by-step explanation:
The answers are:
x + 105 = 180 (Supplementary angles = 180 degrees)
x = z (Vertical angles are congruent)
180 - z = y (Supplementary angles = 180 degrees)

WILL GIVE BRAINLIEST: What is the local minimum value of the function g(x)=x^4-5x^2+4? (Round answer to the nearest hundredth)
Answer:
Step-by-step explanation:
you can find where the first derivative is 0 to find the critical points
g'(x) = ( x^4 -5x^2 +4)' = 4x³-10x
g'(x) =0, make y =0 to find find where g'(x) is 0
4x³-10x =0 , factor 2x
2x(2x²-5)= 0 , each factor must be 0
2x= 0, so x= 0
2x²-5 =0, so x = ±√5/2
we now have 3 critical points -√5/2, 0, and √5/2
make intervals (-∞, -√5/2), (-√5/2, 0) , (0, √5/2) and (√5/2, +∞)
pick a point to test on each interval: -2, -1, 1 and 2 for example, and
calculate g'(x) = 4x³-10x at those points
for x= -2 we have 4(-2)³-10(-2) = -12 , negative number, decrease
for x= -1 we have 4(-1)³-10(-1) =6, positive number, increase
for x= 1 we have 4(1)³-10(1) = -6, negative number, decrease
for x= 2 we have 4(2)³-10(2) = 12, positive number, increase
we went from a decrease to an increase on intervals (-∞, -√5/2), (-√5/2, 0) so x= - √5/2 ≈ -1.58 is a minimum
we went from a decrease to an increase on intervals (0, √5/2), (√5/2, +∞) so
x= √5/2 ≈ 1.58 is a minimum as well

Answer:
Step-by-step explanation:
x+5+x+7x-5=180 degree (being the interior angles of a triangle)
9x=180
x=180/9
x=20 degree
Answer:
x° = 20°
Step-by-step explanation:
Sum of angles of triangles = 180°
Therefore,
(x + 5) + (7x - 5) + x = 180
x + 5 + 7x - 5 + x = 180
9x = 180
x = 20
∠M = (x + 5) = 20 + 5 = 25°
∠L = (7x - 5) = 140 - 5 = 135°
∠N = x = 20°

How do I solve this step by step?
Answer:
x > 67
Step-by-step explanation:
x+3 >70
subtract from each side
x+3-3 > 70 -3
x > 67
Algebra
To solve this, simplify the algebra inequality.
Subtract three from both sides.
x>67
Meaning, x is bigger than 67.

I need help with this question
Answer:
O = 41 degrees
Step-by-step explanation:
the sum of all angles in a triangle is always 180 degrees.
the graphic shows that this triangle has 2 equal sides. that means that both angles at O and at M are equal.
so, we know all three angles and can calculate
7y + 2×(4y - 15) = 180
7y + 8y - 30 = 180
15y = 210
y = 14
so, the angle at O is
O = 4×14 -15 = 56 - 15 = 41 degrees
Math help please due soon thanks
Answer with step-by-step explanation:
I'll use the list of referents you had on your other question and I believe this is a reference to that list.
Part A:
Use the reference of an adult stride (about 1 yard) to estimate the dimensions and length of the lawn edging. The dimensions can be used to find the area, in square yards, that is required to fill both sides of the flower beds.
Part B:
Similarly, you can use an adult stride of about 1 yard as a reference to measure to dimensions of the paved area and the dimensions of the brick. Using these dimensions, you can find area of the paved walkway and the area (surface area of top only) in square yards. Use these areas to find the approximate number of bricks needed to fill the walkway.
Solve for q. Write your answer as “q=___”
Answer:
7q-46= 3q +6
7q-3q = 6+ 46
4q= 52
4q/4= 52/4
q= 13
Answer:
Hello! q = 22
Step-by-step explanation:
This is a supplementary angle meaning it will add up to 180 degrees so...
22 × 7 = 154 154 - 46 = 108
3 × 22 = 66 66 + 6 = 72
108 + 72 = 180 therefore q = 22 hope that helps!
