Answer:
D There is an infinite number of solutions to the system of equations
Step-by-step explanation:
When you put the first equation in standard form by dividing it by 2, you get ...
x -2y = 4
When you put the second equation in standard form by dividing it by 8, you get ...
x -2y = 4
These are the same equation, so describe the same line. There are an infinite number of (x, y) pairs that will satisfy this equation.
There is an infinite number of solutions.

what is the domain and range for this graph?
sry if it’s a bit blurry but the line goes down at (7,0)
Answer:
We cannot exactly see to well, I recommend you do windows key + shift + x or something similar in order to take a built in screenshot.
IF THE INEQUALITY SIGN ON THE POINT (7,0) IS SOMETHING LIKE "O" THEN THE RANGE IS Y<0
So the range is everything below 0.
IF THE INEQUALITY SIGN IS A DOT INSTEAD OF AN O, THEN IT IS
Y≤0
The domain should be 7, because it never strays off of the x-value of 7.

What is 8/11 divided by 4
Answer:
2/11 or
0.181818
Step-by-step explanation:
Because 8/11 in precent form is 72%
So, 72÷4= 18.
If you put 18 in decimal form, it will be:
.18
For the fraction answer, .18 will be 0.22
And 0.22 in fraction form will be 2/11.
So those are your answers.
I hope this helped :)
The division of the equation A = ( 8/11 ) / 4 is A = 0.1818..
What is an Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
Substituting the values in the equation , we get
Let the first fraction be represented as p = ( 8/11 )
Let the second fraction be q = 4/1
Now , the equation is A = 8/11 divided by 4
On simplifying , we get
A = ( 8/11 ) / 4
A = ( 8/44 )
A = 0.181818181..
Therefore , the value of A is a recurring decimal number
Hence , the equation is A = 0.181818..

Answer:

Step-by-step explanation:
The volume (V) of water in the tank is calculated as
V = lbh (l is length, b is breadth and h is height )
Here l = 80, b = 40 and h = 50 , then
V = 80 × 40 × 50 = 160000 cm³
V ( in litres) = 160000 ÷ 1000 = 160 litres , then
number of times = 160 ÷ 10 = 16

3 baguettes
He pays with a £10 note and gets a 90p change.
Sam works out the cost of one baguette as £1.70
Is he correct?
You must show your working out.
Answer:
He is not correct
2 boxes of eggs =1.30+1.30=2.60
1 bottle of juice cost=£2.60
2.60+2.60=£5.20
£10.00-0.90p=£9.10

Answer:
$1.30
Step-by-step explanation:
What you do is add the original 65 cents to the additional 65 cents that were shown to get 130. Since it's more than 100 you make it into dollars, so the final answer is $1.30.
Answer:
$1.30
Step-by-step explanation:
You need to know how coins look like. The middle one is a quarter and the other four are dimes. We know that quarters are worth 25 cents and dimes are worth 10 cents. Because there are 4 dimes, you do 4x10 which is equal to 40. We know that there is only one quarter so we do 40+25 which is equal to 65. Therefore, the tip is 65 cents Then, you add 65 cents to 65 cents again because Faaz had already put 65 cents there. 65+65 is equal to 130. 130 is equal to 1 dollar and 30 cents. Therefore, the tip is $1.30

This here you use Pythagorean Theorem.
Step-by-step explanation:
a^2+b^2=c^2
The longest side is c. And the two legs are a and b.
So it'd be 11^2+x^2=12^2
121+x^2=144
Subtract 121 from both sides.
x^2=23
Then take the √ of x^2 and 23
So √x^2=√23
x=4.8

A process that makes chocolate candy bars has an output that is normally distributed with a mean of 6 oz. and a standard deviation of .01 oz. Determine three sigma control limits for an x-bar (mean) chart assuming a sample size of 10. Group of answer choices UCL
Answer:
Upper Control Limit = 6.03 oz
Lower Control Limit = 5.97 oz
Step-by-step explanation:
Given - A process that makes chocolate candy bars has an output that is normally distributed with a mean of 6 oz. and a standard deviation of .01 oz.
To find - Determine three sigma control limits for an x-bar (mean) chart assuming a sample size of 10.
Proof -
Given that,
μ = 6
σ = 0.01
Z value for 3 sigma process = 3
Now,
Control limits are - μ ± Zσ
Now,
Upper Control limit (UCL) = μ + Zσ
And
Lower Control limit (LCL) = μ - Zσ
Now,
UCL = 6 + 3( 0.01 )
= 6 + 0.03
= 6.03
⇒UCL =6.03 oz
Now,
LCL = 6 - 3( 0.01)
= 6 - (0.03)
= 6 - 0.03
= 5.97
⇒LCL =5.97 oz
∴ we get
Upper Control Limit = 6.03 oz
Lower Control Limit = 5.97 oz

Answer:
m angle BCA =48 degrees
m angle ABC =70 degrees
m angle BAC=62 degrees
m angle BCD=132 degrees
Step-by-step explanation:
First you know that both interior angles have to equal the exterior angles (sorry I forgot what the name of the property). This means that the equation will be 6x-8+4x+10=12x-24. Simplify this to get 10x-2=12x-24. Simplify again to get 2x=26. Divide each side by 2 to get x=13. Now that you know x is equal to 13, you should plug x into angle ABC, BAC, and BCD. When you finish, angle ABC should be 70 degrees, angle BAC should be 62, and BCD should be 132. To find angle BCA, you know that angle ABC is 70 degrees and BAC is 62 degrees. Every triangle has to equal 180 degrees so the equation should be 180-70-62 which is equal to 48. Therefore, m angle BCA =48 degrees, m angle ABC =70 degrees, m angle BAC=62 degrees, and m angle BCD=132 degrees. With this you can mark the correct choices.

What is the area of a regular pentagon with an 8-cm
apothem and 11.6-cm sides?

Answer:
232.5 cm²
Step-by-step explanation:
232.5
The required area of the regular pentagon with an 8-cm apothem and 11.6-cm sides is 232 cm².
What is surface area?The surface area of any shape is the area of the shape that is faced or the Surface area is the amount of area covering the exterior of a 3D shape.
Here,
To find the area of a regular pentagon, we can use the formula:
Area = (1/2) x Apothem x Perimeter
where Apothem is the distance from the center of the pentagon to the midpoint of any side, and Perimeter is the sum of the lengths of all the sides.
In this case, the apothem is given as 8 cm, and the length of each side is given as 11.6 cm.
To find the perimeter, we can simply multiply the length of one side by 5:
Perimeter = 5 x 11.6 cm = 58 cm
Now, we can plug in these values into the formula:
Area = (1/2) x 8 cm x 58 cm
Area = 232 cm²
Therefore, the area of the regular pentagon with an 8-cm apothem and 11.6-cm sides is 232 cm².
