Answer:
Step-by-step explanation:
Maximum capacity of the elevator = 2000 pounds
Combined weight of the elevator = 428 pounds
A). Let the possible weights that can be added to the elevator = w pounds
B). Therefore, inequality representing this situation will be,
428 + w < 2000
C). By solving the given inequality,
(428 + w) - 428 < 2000 - 428
w < 1572 pounds
Now we draw this inequality on a number line.
What is the length of the arc by a central angle of 85 degrees and a radius of 8cm to the nearest tenth of a cm?
9514 1404 393
Answer:
11.9 cm
Step-by-step explanation:
Arc length is given by ...
s = rθ . . . . . . θ is the central angle in radians
Your central angle is 85°, so is (85/180)π radians = 17/36π radians.
Then the arc length is ...
s = (8 cm)(17/36π) ≈ 11.9 cm
The length of the 85° arc is about 11.9 cm.

Find the perimeter of quadrilateral ABCD with vertices A=(1,1) B=(4,4) C=(7,1) D=(4,-2). Explain your answer.
we have the coordinates of ABCD
there are 2 ways of doing this one is you find the distance of ab, bc, cd and da and then add the answers together. there is another way but i dont remember it properly so i am just gonna do it this way
distance between 2 point = [tex]\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}[/tex]
AB
[tex]d = \sqrt {(4 - 1)^2 + (4 - 1)^2}[/tex]
[tex]d = \sqrt {(3)^2 + (3)^2}[/tex]
[tex]d = \sqrt {9 + 9}[/tex]
[tex]d = \sqrt 18[/tex]
AB = 4.24
now repeat the same with all
BC= 4.24
CD= 4.24
DA= 4.24
so its a square with all the same sides so perimeter is 4 x 4.24
perimeter is 16.96

A company used 7.4 x 105 sheets of paper a month, the accounting department used 8.9 x 103 sheets. How many were used by other departments during the month
Answer:
731,100
7.311 × 10^5
Step-by-step explanation:
The computation of the number of sheet used by other department is given below:
Given that
The company used 7.4 × 10^5 sheets of paper So it would be 740,000
And, The accounting department used 8.9 × 10^3 sheets so it would be 8,900
Now the number of sheet used by other department is
= 740,000 - 8,900
= 731,100
= 7.311 × 10^5

C. x^-6x-7=0
Method:
Why:
D. x^2-17x-7=0
Method:
Why:
A. square root property
[tex]3x^2-192=0\\x^2-66=0\\x^2=66\\x= -\sqrt{66} or \sqrt{66}[/tex]
it has one value with x which is x^2 and it cn be easily solved without having to factorise, quadratic formula cant be used as it need ax^2+bx+c=0 format
B. factorising
[tex]x^2-x-6=0\\x^2+2x-3x-6=0\\(x+2)(x-3)=0\\x+2=0 and x-3=0\\x= -2 \\x= 3[/tex]
i just felt like this was easier to factorise than the other 2 options left
C. Completing the square
[tex]x^2-6x-7=0\\(x-3)^2=0\\x= -1\\x= 7[/tex]
same reason personal preference
D- Quadratic
[tex]x^2-17x-7=0\\x=\frac{-(-17)+\sqrt{(-17)^2-4(1)(-7)} }{2(1)} \\x=\frac{-(-17)-\sqrt{(-17)^2-4(1)(-7)} }{2(1)}\\x=17.4\\x=-0.402[/tex]
the 17 kinda threw me off and i didnt wanna get on factorising or doing completing the square so quadratic formal

Answer:
600 square feet
Step-by-step explanation:
I notice it says "Estimate" in bold. Therefore, you would round all of the measurements. They're all pretty simple to round (to the nearest tens place). From here, you subtract the length of the large room from the length of both rooms. So, 50 - 30 = 20. This is the length of the small room. We now multiply this by the width of the small room (since area of a rectangle is length * width) and we get:
20 * 30 = 600, our final answer
Hope it made sense. I would appreciate Brainliest, but no worries.
Write an equation (any form) for the quadratic graphed below. Y=
Answer:
y = -2x^2 - 4x - 1
Step-by-step explanation:
We can see that the graph passes through (-2, -1), (-1, 1) and (0, -1).
Let's solve
ax^2 + bx + c = y
a(-2)^2 + b(-2) + c = -1
4a - 2b + c = -1
a(-1)^2 + b(-1) + c = 1
a - b + c = 1
a0^2 + b0 + c = -1
c = -1
we got c = -1 so we input it into the other 2
4a - 2b - 1 = -1
4a - 2b = 0
2a - b = 0
2a = b
a - b - 1 = 1
a - b = 2
a = b + 2
Let's input b = 2a
a = 2a + 2
-a = 2
a = -2
b = 2a = 2*(-2) = -4
c = -1
y = -2x^2 - 4x - 1
the stove you have to bake in is an old one and only has the temperature in ° Fahrenheit. You are making rusks and have to dry them overnight at a temperature of 176°.Convert this temperature to ° Celsius
Answer:
[tex]80^{\circ} C[/tex]
Step-by-step explanation:
You are making rusks and have to dry them overnight at a temperature of 176° F.
The given temperature is in Fahrenheit. We need to convert it into °C.
The relation between Fahrenheit and °C is given by :
[tex]C=\dfrac{5}{9}(F-32)[/tex]
Put F = 176
So,
[tex]C=\dfrac{5}{9}(176-32)\\\\C=\dfrac{5}{9}\times 144\\\\C=80^{\circ} C[/tex]
So, the temperature is equal to [tex]80^{\circ} C[/tex].

A car uses 1 liter of gas every 12 kilometers. How many meters can the car travel on 3 liters of gas? 36 meters 3,600 meters 360 meters 36,000 meters
Answer:
36,000 meters. 12km= 12,000m multiply by 3l of gas.
Step-by-step explanation:
The car will travel 36000 meters using 3 liters of gas as per linear equation.
What is a linear equation?"A linear equation is an equation in which the highest power of the variable is always 1. It is also known as a one-degree equation. The standard form of a linear equation in one variable is of the form Ax + B = 0. Here, x is a variable, 'A' is a coefficient and 'B' is constant".
Given, a car uses 1 liter of gas every 12 kilometers.
Therefore, using 3 liters of gas, the car will go
= 3 × 36 kilometers
= 36 kilometers
= 36000 meters
With 3 liters of gas, the car will travel 36000 meters.
