Answer:
x = 4.5
Step-by-step explanation:
Solve for x by using the quadratic formula
x = -12 + or - [tex]\sqrt{144+2160}[/tex] / 8
so (-12 + 48) / 8 or (-12 - 48) / 8
so 36/8 or -60/8, they just want the positive solution so x = 4.5
Write the equation in standard form of the line that
passes through the point (4, -2) and has a slope of -1/2.
Answer:
x+2y=0
Step-by-step explanation:
y-y1=m(x-x1)
y-(-2)=-1/2(x-4)
y+2=-1/2x+4/2
y+2=-1/2x+2
y-(-1/2x)=2-2
y+1/2x=0
1/2x+y=0
2(1/2x+y)=2(0)
x+2y=0

Answer:
140 square feet
Step-by-step explanation:
The total area can be calculated by splitting this irregular shape into two quadrilaterals.
In this case, I am splitting it horizontally, but you can do it vertically and get the same answer!
I'm left with a 10 by 8 ft rectangle and an 15 by 4 ft rectangle. So, the total area is equivalent to:
[tex]10*8 + 4*15\\80 + 60\\=140[/tex]

Answer:
b. y = x + 4
Step-by-step explanation:
So we know at x = 0, or the middle black line, the red line is touching 4 so y = 4. 4 is the y intercept so the equation should say "+ 4"
Then, we can see that when the red line increases up by 1 value, it also increases 1 value to the right so that would be 1/1 which equals to 1x.
Therefore the correct answer is y = x + 4

A shipping container will be used to transport several 100-kilogram crates across the country by rail. The greatest weight that can be loaded into the container is 27500 kilograms. Other shipments weighing 6800 kilograms have already been loaded into the container. Write and solve an inequality which can be used to determine xxx, the number of 100-kilogram crates that can be loaded into the shipping container.
Answer:
x ≤ 207 crates
Step-by-step explanation:
Greatest weight of the container = 27,500 kilograms
Weight of other shipment = 6,800 kilograms
Weight of a crate = 100 kilograms
Number of 100-kilogram crates that can be loaded into the shipping container = x
The inequality is
27,500 ≤ 6800 + 100x
27,500 - 6800 ≤ 100x
20,700 ≤ 100x
x ≤ 20,700 / 100
x ≤ 207 crates

Answer:
∠ V = 130°
Step-by-step explanation:
In a parallelogram opposite angles are congruent and consecutive angles are supplementary.
∠ S and ∠ V are not opposite angles, they are consecutive, then
∠ S + ∠ V = 180°
50° + ∠ V = 180° ( subtract 50° from both sides )
∠ V = 130°

3 people invest in a business in the ratio 2:3:5.if the profit from the business is $450 000.how much does each person get?
Answer:
$90,000;$135,000;$225,000Step-by-step explanation:
In this question we have to find the share of each person
First we have to find the sum of all the ratios,
[tex]2 + 3 + 5 \\ = 10[/tex]
Then we have to represent their share as a fraction and then multiply it by the total value,
The share of first person:-
[tex] \frac{2}{10} \times 450000 \\ = 2 \times 45000 \\ = 90000[/tex]
So the first person share is $90,000
The share of second person:-
[tex] \frac{3}{10} \times 450000 \\ = 3 \times 45000 \\ = 135000[/tex]
So the second person share is $135,000
The share of third person:-
[tex] = 450000 - (135000 + 90000) \\ = 450000 - 225000 \\ = 225000[/tex]
So the third person share is $225,000

Step-by-step explanation:
Hey There! Allow me to explain how to solve this (I will not say the answer bc I also don't know but here is how you can find it). As you see the shape is a Cyclinder & the formula for it is V=Bh or V=πr2h. You might wanna start with solving the problems (8x - 4) & (11x + 12) Use the order of PEMDAS (Parrenthesis, Exponets, Multiplication, Division, Addition, Subtraction.) to solve is so if solving (8x - 4) And if x = 8 than first begin with mutiliplying 8 x 8 (Because it says 8x and x = 8 which means we are multiplying) than subtract that with 4 (Which will be 64 - 4). Than for (11x + 12) you will wanna do 11 x 8 which is 88 added by 12 which that will be 100. Than use the formula (V=Bh or V=πr2h) And you should have you're answer! I hoped this help and sorry for not finding the answer but atleast I explained to you on how to solve it! <3

a. y=-2.5x+50
b. slope=-2.5. y-intercept=50
Answer:
slope is -2.5
y-intercept is (0,50)
slope y-intercept is y= -2.5x + 50
Step-by-step explanation:
to find the slope you use rise/run the rise is 5 and the run is -2 which is 5/-2 or -2.5
the y-intercept is where the line hits a perfect point on the y-axis which would be at 50 in your case
y=mx+b
m= slope and b= y-intercept
why is m the slope? because the slope is the unknown variable

Answer:
x=40
Step-by-step explanation:
x + 320 = 360
-320 -320
x = 40
Answer:
x=40
Step-by-step explanation:
So, since the figure has 4 sides, we know that the sum of the interior angles is 360. To check: (n-2)*180=(4-2)*180=28180=360.
That means x equals 360 minus the sum of the other three angles.
100+120+100=320
360-320=40
x=40 degrees
Which two angles do NOT represent adjacent angles?
A 21 and 26
B 23 and 22
C23 and 24
D 25 and 22

Lab group A got a residual of 14.1005 grams of silver at the end of an experiment. Lab group B got a residual of 11.023 grams of silver at the end of a similar experiment. Using significant digits, find how much more silver lab group A got compared to lab group B.
A. 3.077 g
B. 3.0775 g
C. 3.078 g
D. 3.75 g
Answer:
C. 3.078
Step-by-step explanation:
14.1005 - 11.023 = 3.0775
Then you round the ten thousands place turning 75 into 8 equaling 3.078
Subtraction is a mathematical operation. The amount of silver lab group A got compared to lab group B is 3.0775 gm more.
What is subtraction?Subtraction is a mathematical operation that reflects the removal of things from a collection. The negative symbol represents subtraction.
The amount of silver that group A got is 14.1005gm, while the amount of silver that group B got is 11.023 grams. Therefore, the amount of silver lab group A got compared to lab group B is,
14.1005 gm - 11.023 gm = 3.0775 gm
Hence, the amount of silver lab group A got compared to lab group B is 3.0775 gm more.
