Answer: 722.5 yards
Step-by-step explanation:
85 x 25.5 = 2167.5 feet for 85 wood beams.
Convert 2167.5 feet to yards.
There are 3 feet in 1 yard; so divide 2167.5/3 which equals 722.5 yards
3. What kind of triangle has angles measuring
37°, 85°, and 58°?
Answer:
Acute triangle
Step-by-step explanation:
All of the triangles vertices are under 90 degrees.
For future reference:
Vertex (plural: vertices)= corner
Acute triangle: each vertex <90 degrees
Right triangle: One vertex = 90 degrees
Obtuse triangle: All vertices >90 degrees
someone help i found the slope already.
Answer:
s(x)
Step-by-step explanation:
s(x) is a linear function, so the average rate of change is its slope.
Its slope is 3.
You are correct.
To find the average rate of change of polynomial function t(x) from -2 to 2, find the values of t(x) at x = -2 and at x = 2.
average rate of change = [t(2) - t(-2)]/[2 - (-2)]
t(x) = 0.1(x^3 - x^2 + 2)
t(-2) = 0.1[(-2)^3 - (-2)^2 + 2)]
t(-2) = 0.1(-8 - 4 + 2)
t(-2) = -1
t(2) = 0.1[(2)^3 - (2)^2 + 2)]
t(2) = 0.1(8 - 4 + 2)
t(2) = 0.6
average rate of change = [t(2) - t(-2)]/[2 - (-2)]
average rate of change = [0.6 - (-1)]/4
average rate of change = 1.6/4
average rate of change = 0.4
average rate of change for s(x) = 3
average rate of change for s(x) = 0.4
Answer: s(x)

(Choice A)
A
Greater width always relates to smaller area.
(Choice B)
B
Greater width relates to smaller area as long as the width is less than 10\text{ m}10 m10, start text, space, m, end text.
(Choice C)
C
When there is no width, the area is 20\text{ m}^220 m

(Choice D)
D
When there is no width, the area is 0\text{ m}^20 m
2
0, start text, space, m, end text, squared.
Answer:
When there is no width, the area is 0m²
Step-by-step explanation:
Expressing the area of a rectangle as a function of its width:
Area of a rectangle = Length * width
Since the area of rectangle is related to the width by the multiplication operatkr. We can conclude from the options given that ; if the value of width = 0 ; the the area of rectangular plot = 0
When x :
Area = Length * width
Area = Length * 0
Area = 0
Area = Length * 0
Aea = 0

Mathematics Question!
Mika estimated the sum of 189.27, 15.8, and 11.2 by rounding each number to the nearest whole.
What was Mika’s estimate and what is the actual sum of the numbers?
Enter your answers in the boxes
Mika estimated the sum to be blank. The actual sum is blank
PLEASE DON’T ANSWER IF YOU DON’T NO THE ANSWER!
Answer:
Mika's estimated the sum to be 216. The actual sum is 216.27
Step-by-step explanation:
Mika:
189.27 = 189
15.8 = 16
11.2 = 11
189 + 16 + 11 = 216
Actual:
189.27 + 15.8 + 11.2 = 216.27

Answer:
a = 15, b = -14
Step-by-step explanation:
From the question,
a/5 - b/2 = 10
Multiply all through by 10
(a/5)10 - (b/2)10 = 10×10
2a - 5b = 100...................... Equation 1
a - b = 29 ........................ Equation 2
Solving equation(1 ) and equation (2) simultaneously
using elimination method,
multiply equation (2) by 2.
2a - 2b = 58.................... Equation 3
Substract equation 3 from equation 1
2a - 2a -5b-(-2b) = 100-58
0 - 5b+2b = 42
-3b = 42
b = 42/-3
b = -14.
Substitute the value of b into equation 2
a - (-14) = 29
a +14 = 29
collect like terms
a = 29-14
a = 15.
Hence, a = 15, b =-14

Answer:
90 - 37 will give a solid 53
Step-by-step explanation:
the two sums of A to C to C to B so 22.9(C, B) and 14.1 (A, C)
and know that this angle is 90 degrees, my guess would be to subtract the to given numbers with degrees to earn the sum so 22.9 + 14.1 equals 37
now we add angle degrees and sum and subtract one another,
90 - 37
yeah i kinda drug my way through this whole lesson because i was lazy and now im kinda in deep water so help pls
Answer:
127.5
Step-by-step explanation:
First, we need to find the value of x
since the two angles are connected to a straight line, their sum will be 180 (degrees)
[tex](2x+7)+(6x-9)=180^{o}[/tex]
add the angles together
[tex]\therefore 8x-2=180[/tex]
add 2 to both sides
[tex]\therefore 8x=182[/tex]
divide out by 8
[tex]\therefore x = 22.75[/tex]
now we must determine which angle has the greater value (not visually)
[tex]angle A = 2x+7[/tex]
[tex]\therefore \angle{A} = 2(22.75)+7[/tex]
[tex]\therefore \angle{A} = 45.5+7[/tex]
[tex]\therefore \angle{A} = 52.5[/tex]
[tex]angle B = 6x-9[/tex]
[tex]\therefore \angle{B} = 6(22.75)-9[/tex]
[tex]\therefore \angle{B} = 136.5-9[/tex]
[tex]\therefore \angle{B} = 127.5[/tex]
[tex]\angle{B}>\angle{A}\ \because\ 127.5>52.5[/tex]
so the answer would be 127.5

Mark is installing a mosaic tile backsplash and the shape of the tiles are shaped like regular octagons. Each tile has a length from side to side of 6 in. Once Mark gets a few pieces on the wall, he realized that there is a gap that the tiles do not cover. What size tile must he get to fill the gaps?
Answer:
square with sides of 6 in
Step-by-step explanation:
Tessellation is the arrangement of shapes in repeated patterns without gaps or overlapping.
Tessellation is usually done with regular polygons. Only three regular shapes can tessellate, these are equilateral triangle, regular square and regular hexagon. For other polygon to tessellate, more than one shape must be used. A octagon can be used to make tessellations if it is used together with a square.
Mark uses tiles with shape of octagon of sides 6 in. To fill the gaps, Mark have to uses a square with sides of 6 in
