Answer:
Step-by-step explanation:
Given the perimeter of the rectangular shape = 170m
Length of the diagonal = 130m
Perimeter = 2L + 2W
diagonal d² = L² + w²
L is the length of the terrain
w is the width
140 = 2L + 2W
70 = L+W ..... 1
130² = L²+w² ..... 2
from 1, L = 70-w
substitute into 2;
130² = (70-w)²+w²
130² = 4900-140w + 2w²
16900 = 4900-140w + 2w²
2w²-140w - 12000 = 0
w²-70w - 6000 = 0
On factorizing;
(w+50)(w−120) = 0
w - 120 = 0
w = 120 m
Since L = 70 - w
L = 70 - 120
L = -50m
Hence the dimension is 120m by 50 m

Answer:
25 should be the answer.
Step-by-step explanation:
8* x + y + y; use x=9, and y = 10
Answer:
If we have 8 * x + y + y:
We have to first substitute in x and y where they should be:
=> 8 * 9 + 10 + 10
According to the order of operations(PEMDAS(parenthesis, exponents, multiplication, division, addition, subtraction, multiplication and division is you go from left to right order, and same with addition and subtraction.)), we do the multiplication first(8*9):
=> 72 + 10 + 10
Now we just add them up:
=> 92
Which weighs more: a pumpkin that weighs 3.2 kilograms, or a cat that weighs 9 pounds?
Answer:

15 16 18 01:34:02 Kate begins solving the equation (6x – 3) = }(6x – 4). When she adds 2 to both sides, the equation 4x = 3x results. Which solution will best illustrate what happens to x ? Her work is correct and is shown below. (6x – 3) = (6x – 4) O The equation has infinite solutions. O The equation has one solution: x = 0. 4x - 2 = 3x - 2 O The equation has one solution: x = 4 O The equation has no solution.
The true statement is that the equation has one solution; x = 0
How to determine the equation solution?We have:
2/3(6x – 3) = 1/2(6x – 4)
When 2 is added to both sides, the equation becomes
4x = 3x
Subtract 3x from both sides of the equation
x = 0
Hence, the equation has one solution; x = 0

A computer store buys a computer system at cost of 572.40 cents the selling price was first at 9:54 but then the store was advised at 20% markdown on the system answer parts a and b
Answer: See explanation
Step-by-step explanation:
A. Find the current sale price. Round to the nearest cent if necessary.
B) Members of the stores loyalty club can and additional 10% off their computer purchases. How much do club members pay for the computer with their discount.
A. Current sales price will be:
= $954 - (20% × $954)
= $954 - (0.2 × $954)
= $954 - $190.80
= $763.20
B. Club members will pay:
= $763.20 - (10% × $763.20)
= $763.20 - (0.1 × $763.20)
= $763.20 - $76.32
= $686.88

What do you think is the importance of having a hyperboloid structure in most of the power plants?
Answer:
Cooling Tower
A power plant consists of many components, but cooling towers are some of the most important. The function of a cooling tower is to release the excess heat (or waste heat) to the atmosphere by cooling down hot fluid (water, in most cases) to a lower temperature.

The teachers need to buy eggs and plastic spoons for the egg race event. The teachers want to have 1 egg for every spoon. The eggs are sold in packs of 6 , and the spoons are sold in packs of 10 . If the teachers want to buy exactly 30 spoons and have no leftovers, they need to buy
Answer:
5 packs of eggs
3 packs of spoons
Step-by-step explanation:
Eggs are sold in packs of 6
Spoons are sold in packs of 10
The teachers want to have 1 egg for every spoon
Find the Lowest common multiple of 6 and 10
6 = 12, 18, 24, 30, 36, 42, 48, 54, 60
10 = 20, 30, 40, 50, 60
The lowest common multiple of 6 and 10 is 30
If the teachers want to buy exactly 30 spoons and have no leftovers
Eggs are sold in packs of 6
Number of packs needed = 30 /6
= 5 packs
Spoons are sold in packs of 10
Number of packs needed = 30/10
= 3 packs
The teacher will buy 5 packs of eggs and 3 packs of spoons to have exactly 30 spoons and have no leftovers

Answer: -9/4
Step-by-step explanation:
First you subtract 7/2 from both sides of the equation
3x + 7/2 - 7/2= x - 1 - 7/2
Next what you do is simplify one you add 3 + 7/2 which is 9/2
Then you subtract X from both sides of the equation
3x - x = x - 9/2 - x
combine the terms
2x = -9/2
divide both sides of the equation by the same term
2x/2 = 9/2 / 2
cancel the terms and divide the numbers
x=-9/4

Solve 6.1−0.3≥c+1.
please help me
Answer:
c≤ 24/25
Step-by-step explanation:
"0.3" was replaced by "(3/10)". 2 more similar replacement(s). Simplify 3/10
61 3
(—— - ——) - (c + 1) ≥ 0 then simplify 61/10
10 10
3.1 Adding fractions which have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
61 - (3) 29
———————— = ——
10 5
29
—— - (c + 1) ≥ 0
5
4.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 5 as the denominator :
c + 1 (c + 1) • 5
c + 1 = ————— = ———————————
1 5
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Rewrite the whole as a fraction using 5 as the denominator :
c + 1 (c + 1) • 5
c + 1 = ————— = ———————————
1 5
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:
29 - ((c+1) • 5) 24 - 5c
———————————————— = ———————
5 5
24 - 5c
——————— ≥ 0
5
Multiply both sides by 5
5.2 Multiply both sides by (-1)
Flip the inequality sign since you are multiplying by a negative number
5c-24 ≤ 0
5.3 Divide both sides by 5
c-(24/5) ≤ 0
5.4 Add 24/5 to both sides
c ≤ 24/5

Answer:
The ladder will go approximately 35.71 ft up the building.
Step-by-step explanation:
The 50 ft ladder is leaning against a building and the base of the ladder is 35 feet from the base of the building.
It means the ladder will form a right triangle with the building with the following dimensions:
base = 35 f t hypotenuse = 50 f t height = ?Using the Pythagorean Theorem to determine the height,
[tex]a^2+b^2=c^2[/tex]
Here,
a is the heightb is the basec is the hypotenuseSubstitute the given values into the equation to determine the height:
[tex]a^2+b^2=c^2[/tex]
[tex]a^2+\left(35\right)^2=\left(50\right)^2[/tex]
[tex]a^2+1225=2500[/tex]
[tex]a^2=1275[/tex]
[tex]\mathrm{For\:}x^2=f\left(a\right)\mathrm{\:the\:solutions\:are\:}x=\sqrt{f\left(a\right)},\:\:-\sqrt{f\left(a\right)}[/tex]
[tex]a=\sqrt{1275},\:a=-\sqrt{1275}[/tex]
[tex]a\:=\:35.71,\:\:\:a\:=\:-35.71[/tex]
We know that height can not be negative. Thus,
[tex]a=35.71[/tex] ft
Therefore, the ladder will go approximately 35.71 ft up the building.
