2. The speed limit on a city street is 35 kilometers per hour. Write and graph an inequality to
describe a car’s possible speed.
Answer:
[tex]x\leq 35[/tex] where [tex]x[/tex] denotes speed of the car
Step-by-step explanation:
Given: The speed limit on a city street is 35 kilometers per hour.
To write and graph: an inequality to describe a car’s possible speed.
Solution:
Let the speed of a car be [tex]x[/tex] kilometers per hour.
As the speed limit on a city street is 35 kilometers per hour,
[tex]x\leq 35[/tex]
First draw the graph of [tex]x=35[/tex] (see figure a.)
Plot the points [tex](35,0),(35,5),(35,10),(34,15)[/tex]
Take a point on the left side of line x = 35 say [tex](x,y)=(0,0)[/tex] and put it in [tex]x\leq 35[/tex]
[tex]0\leq 35[/tex] which is true.
So, shade the graph on the left side of line x = 35
See the graph b.
the pink part represents the inequality [tex]x\leq 35[/tex]

In choice a:
The smallest square line would be from the production.
[tex]Sales = -7.567857143 + 0.917857143 \times Makeup\ Videos.[/tex]
Purchases of Cosmetics & Makeup Demo Clips are the factors used in the calculation.
In choice b:
The proportions of its variance of maquillage sales reveal by it's a linear relation to maquillage video tutorials is [tex]99.53 \ \%[/tex].
In choice c:
Because the vector Cosmetics Demonstration videos are critical with 5.11E-07 p-value, which is less than 0.05 and[tex]R^2 = 99.53[/tex]. It may assume that increasing making-up purchases is attributed to tutorials for online makeup.

Answer:
B) x<= 0
Step-by-step explanation:
of you look at the graph, the line stops at the coordinates (0, 9)
the x coordinate here is 0. so x<0.
since it's a closed circle around where the line ends, the domain becomes
x <=0
the rest of the line goes on for infinity, so that's all of the equation.

Which triangle's circumcenter would lie on the triangle?
123
The triangle's circumcenter would lie on the triangle will be middle of the hypotenuse. Then the correct option is A.
What is the triangle?The polygonal shape of a triangle has a number of sides and three independent variables. Angles in the triangle add up to 180°.
It is the close curve of an equidistant point drawn from the center. The radius of a circle is the distance between the center and the circumference.
We know that the circumcenter is the circle that passes through the vertices of the triangle.
In a right-angle triangle, the hypotenuse represents the diameter of the circle. Then the center of the circle lies in the middle of the hypotenuse of the right-angle triangle.
The triangle's circumcenter would lie on the triangle will be middle of the hypotenuse. Then the correct option is A.

Solve the following equation for f. Be sure to take into account whether a letter is capitalized or not.
N2=6f+H
Answer:
f = (N² - H)/6
Step-by-step explanation:
Step 1: Write equation
N² = 6f + H
Step 2: Solve for f
Subtract H on both sides: N² - H = 6fDivide both sides by 6: (N² - H)/6 = fRewrite: f = (N² - H)/6In ΔLMN, \overline{LN} LN is extended through point N to point O, \text{m}\angle NLM = (x-4)^{\circ}m∠NLM=(x−4) ∘ , \text{m}\angle MNO = (4x-17)^{\circ}m∠MNO=(4x−17) ∘ , and \text{m}\angle LMN = (x+9)^{\circ}m∠LMN=(x+9) ∘ . What is the value of x?X?
Answer:
11°
Step-by-step explanation:
Kindly find the diagram attached.
From the diagram we are given two interior angles ∠NLM and ∠LMN and exterior angle ∠MNO.
You must understand that sum of interior angles is equal to the exterior angles.
∠NLM+ ∠LMN = ∠MNO
Given parameters
∠NLM = x-4
∠LMN = x+9
∠MNO = 4x-17
Substitute the given parameters into the equation above;
x-4+x+9 = 4x-17
2x+5 = 4x-17
2x-4x=-17-5
-2x = -22
x = -22/-2
x = 11°
Hence the value of x is 11°

Danielle and Emilia brought apples, bananas, and oranges to a fruit sale.
The bananas were sold for $0.50 each, while the apples and oranges
were sold for $0.75 each. They sold 50 pieces of fruit and earned $33.50
total. If Danielle and Emilia sold twice as many bananas as oranges, how
many apples did they sell? Show your work.
*
Can you please Write the system which models this situation as well!!
Answer:
26 apples
Step-by-step explanation:
bananas, b= $0.50
oranges, o= $0.75
apples, a = $0.75
Total fruit sold = 50
Total Earned = $33.50
b + o + a = 50 Because the total number of all 3 fruits sold is 50
.5b + .75o + .75a = $33.50 The number of each fruit, multiplied by the price of each fruit, and added together is $33.50
They sold twice as many bananas than oranges.
If o is oranges, then 2o = b because there are twice as many bananas so:
b + o + a = 50
2o + o + a = 50
3o + a = 50
Now we can solve.
3o + a = 50
a = 50 - 3o
.5b + .75o + .75a = $33.50
.5(2o) + .75o + .75a = $33.50
o + .75o + .75a = $33.50
1.75o + .75a = $33.50
Two equations and 2 unknowns.
a = 50 - 3o
1.75o + .75a = $33.50 Plug in a to solve for o.
1.75o + .75(50 - 3o) = $33.50
1.75o + .75*50 - .75*3o = $33.50
1.75o + 37.5 - 2.25o = $33.50 Combine like terms
1.75o - 2.25o +37.5 = $33.50
-.5o + 37.5 = 33.5 Add .5o to each side so it cancels on the left.
37.5 = 33.5 + .5o Subtract 33.5 from each side
37.5 -33.5 = .5o
4 = .5o Divide each side by .5
4/.5 = o
8 = o
Now plug into a = 50 - 3o
a = 50 - 3(8)
a = 50 - 24
a = 26
So even though we know they sold 26 apples, let's finish solving to check our work.
b + o + a = 50
b + 8 + 26 = 50
b + 34 = 50
b = 50 - 34
b = 16
b = 2o
b = 2 (8)
b = 16 Which works! Now the last step of checking our work:
.5b + .75o + .75a = $33.50
.5(16) + .75(8) + .75(26) = $33.50
8 + 6 + 19.5 = $33.50
14 + 19.5 = $33.50
33.5 = $33.50 Yes! It works too!
bananas = 16
oranges = 8
apples = 26

What is the 7th term of the geometric sequence?
2, 8, 32, 128, ...
To find the 7th term of the geometric sequence 2, 8, 32, 128, ..., we must first determine the common ratio between consecutive terms.
The common ratio, denoted by 'r', is found by dividing any term by its preceding term. In this case, dividing 8 by 2 gives us a common ratio of 4. Now that we know the common ratio, we can use the formula for the nth term of a geometric sequence, which is given as: [tex]aₙ = a₁ * r^(n-1)[/tex]
Here, aₙ represents the nth term of the sequence (the term we are trying to find), a₁ is the first term (2 in this case), r is the common ratio (4 in this case), and n is the position of the term we are trying to find (7 in this case). Plugging in the given values, we get: a₇ [tex]= 2 * 4^(7-1) = 2 * 4^6 = 2 * 4 * 4 * 4 * 4 * 4 * 4 = 2 * 4,096 = 8,192[/tex]Therefore, the 7th term of the geometric sequence 2, 8, 32, 128, ... is 8,192.

On a scale drawing of Caleb's house, the four bedroom walls each measure 10 inches wide by 6 inches tall. The scale of the drawing is 1 inch = 1.5 feet. Caleb will paint all four walls. If a gallon of paint covers 250 square feet, how many gallons of paint will Caleb need?
Answer:
Approximately 2 gallons of paint are required to paint four bedroom walls
Step-by-step explanation:
Dimensions of the four bedroom walls = 10 inches wide by 6 inches tall
As 1 inch = 1.5 feet,
10 inches [tex]=10(1.5)=15[/tex] feets
6 inches [tex]=6(1.5)=9[/tex] feets
Dimensions of the four bedroom walls = 15 feets wide by 9 feets tall
Area of one wall = product of the dimensions [tex]=15(9)=135[/tex] square feets
Area of four walls = [tex]4(135)=540[/tex] square feets
Area of four walls covered by a gallon of paint = 250 square feets
So,
Amount of paint required = [tex]\frac{540}{250}=2.16[/tex]
That is approximately 2 gallons of paint are required to paint four bedroom walls
