Answer :
no. of days used to repair 1250m of road = 5
no. of days used to repair 1m of road = 5/1250
no. of days used to repair 8000m of road (8*1000m ) = 5/1250*8000= 32 days

The first side of a triangle is 4 inches longer then twice th second side the third side of a trianhle
Question:
The first side of a triangle is four inches longer than twice the
second side. The third side of the triangle is 5 inches shorter than
the sum of the other two sides. The perimeter is 72 inches. Find
the lengths of the three sides.
Answer:
The sides of the triangle are: 11.5, 27 and 33.5
Step-by-step explanation:
Let the first side be f, the second be s and the third be t.
So, we have:
[tex]f =4 + 2s[/tex]
[tex]t = f + s - 5[/tex]
[tex]Perimeter = 72[/tex]
Required
Determine the length of the three sides
Perimeter is calculated as:
[tex]Perimeter = f + t + s[/tex]
Substitute values for f and t
[tex]Perimeter = 4+2s + f+s-5 + s[/tex]
[tex]Perimeter = f+2s +s+s-5+4[/tex]
[tex]Perimeter = f+4s-1[/tex]
Substitute values for f and Perimeter
[tex]72 = 4+2s+4s-1[/tex]
[tex]72 = 2s+4s-1+4[/tex]
[tex]72 = 6s+3[/tex]
Collect Like Terms
[tex]6s = 72 -3[/tex]
[tex]6s = 69[/tex]
[tex]s= 11.5[/tex]
[tex]f =4 + 2s[/tex]
[tex]f = 4 + 2 *11.5[/tex]
[tex]f = 27[/tex]
[tex]t = f + s - 5[/tex]
[tex]t=27+11.5 - 5[/tex]
[tex]t=33.5[/tex]
The sides of the triangle are: 11.5, 27 and 33.5

Answer:
(B)
Step-by-step explanation:
x is on the left side of the < symbol, so the shaded portion of the line will be on the left side of the boundary dot.
The boundary dot is plotted at the constant, which is 1/2 = 2/4. That plot is shown in selection B.
_____
Additional comment
I like to write inequality solutions using the < or ≤ symbols because the relative positions of numbers and variables match their relative positions on the number line. In this problem, we have x < 1/2, so the shaded portion of the line is on the left of the boundary dot, just as x is on the left of 1/2 in the inequality.

Alex bought a present for his friend. The box, with its dimensions, is shown below.
If Alex has 60 square inches of wrapping paper, does he have enough paper to wrap the gift? (Assume that the shape of the wrapping paper doesn't matter.)
O yes because the gift has a surface area of 48 square inches
O no because the gift has a surface area of 96 square inches
O yes because the gift has a surface area of 32 square inches
O no because the gift has a surface area of 64 square inches
Answer:
yes because the gift has a surface area of 48 square inches
Step-by-step explanation:
Surface area formula:
A = 2(wl + hl + hw)
2 · (4 · 4 + 1 · 4 + 1 · 4) = 48

The length of Bryan’s garden is 4 meters longer than 3 times the width. The perimeter of his garden is 72 meters. What are the dimensions (l, w) of his garden?
Answer:
8 m = width
28 m = length
Step-by-step explanation:
Let w = width
3w + 4 = length
P = 2w + 2l
= 2w + 2(3w + 4) = 72
2w + 6w + 8 = 72
8w + 8 = 72
8w = 64
w = 8 m = width
3w + 4 = 24 + 4 = 28 m = length

Answer:
Step-by-step explanation:
How many people used the public pool altogether? There isn't enough info
Anyways,
You would write two equations and solve using substitution / elimination / graphing
one equation is:
1.5x + 2.25y = 1258.5

Answer:
aproximately 23.5 I believe
Step-by-step explanation:
ok, so first you square 17, which is 289. then you square 29, which is 841. subtract 289 from that:
841-289=552
now take the square root of 552
aproximately 23.5 I believe
Answer: 23cm
Step-by-step explanation:
a² + b² = c²
x² + 17² = 29²
x² + 289 = 841
x² = 552
√x² = √552
x ≈ 23 cm
Which of the following relations are functions?^^
Answer:
its c because the x is not repeating so let's say x are people and y is the are the location. multiple x values can give the the same y but an x value can only give one y if x give more than one y value, or in other words repeats itself, then is not a function
