This is a Desmos question please help me
Answer:
B
Step-by-step explanation:
If the 2 lines were parallel, then
5x - 10 = 70 ( alternate angles )
Add 10 to both sides
5x = 80 ( divide both sides by 5 )
x = 16
For the 2 lines to be parallel then x = 16
Answer:
B.16
Step-by-step explanation:
First I would Make an equation:
For example set (5x-10)=70
Add 10 to both sides:
5x-10+10=70+10
Simplify:
5x=80
Divide both sides by 5:
5x/5=80/5
simplify:
x=16
In conclusion the answer is B.16

The number from the equation is less than 11
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 number be = x
Now , the equation is
Sum of a number and 3 more than twice the number is less than 36
Let us assume the sum of the numbers is 36
So ,
x + 3 more than twice the number = 36
And ,
x + ( 3 + 2x ) = 36
On simplifying the equation , we get
3x + 3 = 36
Subtracting 3 on both sides , we get
3x = 33
Divide by 3 on both sides , we get
x = 11
But , the inequality equation is less than 36
So , x < 11
Therefore , the number is less than 11
Hence , the number from the equation is less than 11

Complete parts a. and b. below. a. How many text messages would have to be sent or received in order for the plans to cost the same each month? In order for the plans to cost the same. text messages would have to be sent or received
Answer:
a. 50 texts per month (you didn't include part b, sorry!)
Step-by-step explanation:
the difference in the plans is $10, so you have to find the number of texts that equal $10
$10/$0.20 = 50 text messages

A hot dog vendor at Wrigley Field sells hot dogs for $1.50 each. He buys them for $1.20 each. All the hot dogs he fails to sell at Wrigley Field during the afternoon can be sold that evening at Comiskey Park for $1 each. The daily demand for hot dogs at Wrigley Field is normally distributed with a mean of 40 and a standard deviation of 10.a. If the vendor buys hot dogs once a day, how many should he buy?b. If he buys 52 hot dogs, what is the probability that he will meet all of the day’s demand for hot dogs at Wrigley?
Answer:
43 ; 0.88493
Step-by-step explanation:
Using the Zscore formula :
Zscore = (x - m) / s
m = mean ; s = standard deviation
Profit = $1.5 - $1.2 = $0.3
Loss = $1.2 - $1 = 0.2
Cummlative probability :
Profit / (profit + loss)
0.3 / (0.3 + 0.2) = 0.3 / 0.5 = 0.6
To obtain the x, at Z at 0.6 = 0.26
m = 40 ; s= 10
Hence,
0.26 = (x - 40) / 10
0.26 * 10 = x - 40
2.6 = x - 40
2.6 + 40 = x
x = 42.6 `; 43 approximately
Probability of meeting day's demand at Wrigley
x = 52
P(x < 52) :
Zscore = (52 - 40) / 10
P(Z < 1.2)
Z = 0.88493

11. An old machine requires three times as many hours to complete a job as
a new machine. When both machines work together, they require 9 hours
to complete a job. How many hours would it take the new machine to
finish the job operating alone?
Answer:
Step-by-step explanation:
[tex]9(r_n+r_o)=1\\ \\ r_n+r_o=\frac{1}{9}\\ \\ r_o=\frac{r_n}{3}\\ \\ r_n+\frac{r_n}{3}=\frac{1}{9}\\ \\ \frac{4r}{3}=\frac{1}{9}\\ \\ 4r=\frac{1}{3}\\ \\ r=\frac{1}{12}\\ \\ \text{So working alone it would take the new machine 12 hours to finish the job.}[/tex]

A is the poin 3,5 and b is the point 0,k if the distance of ab is 5 units find the possible value of k
Answer:
K is either 9 or 1
Step-by-step explanation:
Sqrt((0 - 3)² + (k - 5)²) = 5
Square both sides
(0 - 3)² + (k - 5)² = 5²
(0 - 3)² + (k - 5)² = 25
-3² + (k - 5)² = 25
9 + (k-5)(k-5) = 25
9 + k² - 5k - 5k + 25 - 25 = 0
k² - 10k +9 = 0
k² - 9k - k + 9 = 0
k(k - 9) - 1(k - 9) = 0
k - 1 = 0 ; k = 1
k - 9 = 9; k = 1
K = 9 or k = 1
K is either 9 or 1
