The car consumes 6 liters per 100 km. How many kilometers can you drive with this car if the tank has 42 liters?
Answer:
If 100km enables consumption of 6lts
what about 42lts
42/6 multiply by 100km
42/6*100= 700km
The car will consume 42lts in 700 km.

Answer:
B
Step-by-step explanation:
Given
x² - 9x + 18 = 0 ← in standard form
(x - 3)(x - 6) = 0 ← in factored form
Equate each factor to zero and solve for x
x - 3 = 0 ⇒ x = 3
x - 6 = 0 ⇒ x = 6
solution is x = 3, x = 6 → B
School administrators in Boston want to assess the efficacy of a new reading program they wish to put in place. Therefore, they randomly assign some schools in the city to institute the new reading program and other schools to remain on the traditional reading program. When performing the analysis to determine whether students using the new reading program perform better, the educators control for socioeconomic status, a variable known to be related to educational outcomes. What kind of analysis have the educators performed
Answer:
The selection of the schools is done by random sampling, the remaining schools are considered as the control and stratified sampling for the selection of students for analysis is considered
Step-by-step explanation:
Based on the scenario, the following key highlights are presented:
The sampling for selection is carried out randomly.The control group is maintained.The selection of students for analysis is considered with a specific socio-economic status.This indicates that the selection of the schools is done by random sampling, the remaining schools are considered as the control and stratified sampling for the selection of students for analysis is considered.

(450) + (28.75x) = 967.50
solve for x
Answer:
18
Step-by-step explanation:
Hello,
In order to solve for x, we need to isolate the variable on one side of the equation.
To do this, we subtract 450 from both sides of the equation, and this will give you:
28.75x = 517.5
As mentioned, we need to isolate x, so we divide both sides by 28.75. This will give the following.
x = 18
Hope this helps!

2. Describe a rigid motion or composition of rigid motions that maps the rectangular bench at (0, 10)and
the adjacent flagpole onto the other short rectangular bench and flagpole.
Answer:
See Explanation
Step-by-step explanation:
Given
Let the bench be B and the flagpole be T.
So:
[tex]B = (0,10)[/tex] --- given
The flagpole is represented by the triangular shape labelled T.
So, we have:
[tex]T = (6,9)[/tex]
See attachment for the rectangular bench and the flagpole
From the attached image, the location of the other bench is:
[tex]B' = (0,-10)[/tex]
And the location of the other flagpole is:
[tex]T' = (-6,9)[/tex]
So, we have:
[tex]B = (0,10)[/tex] ==> [tex]B' = (0,-10)[/tex]
[tex]T = (6,9)[/tex] ==> [tex]T' = (-6,9)[/tex]
When a point is reflected from [tex](x,y)[/tex] to [tex](x,-y)[/tex], the transformation rule is reflection across x-axis.
So the rigid transformation that takes [tex]B = (0,10)[/tex] to [tex]B' = (0,-10)[/tex] is: reflection across x-axis.
When a point is reflected from [tex](x,y)[/tex] to [tex](-x,y)[/tex], the transformation rule is reflection across y-axis.
So the rigid transformation that takes [tex]T = (6,9)[/tex] to [tex]T' = (-6,9)[/tex] is: reflection across y-axis.

AX and EX are secant segments that intersect at point X.
What is the length of DE?
1 unit
3 units
4.5 units
4 2/3 units
Answer:
DE=4
Step-by-step explanation:
got it right on edg
The length of DE is given as: 3 Units. (Option B)
A line that joins two points on a curve is called a Secant Line.
What is the Secant Theorem?
Two secant theorem states that if two secant lines are drawn from a point outside a circle a relationship is formed between the line segments.
How do we arrive at the length of DE?Based on the Secant Theorem, from the figure, we know that:
AX * BX = EX * DX
Assuming that the length of DE equals X,:
AX * BX = EX * DX
Equals
(7+2) X (2) = (x + 3) (3)
To solve for x we expand the brackets to state:
9 * 2= 3x + 9
3x = 18-9
3x= 9
x = 9/3
X which is same as DE = 3 Units.

im confused-
Step-by-step explanation:
1. the height of a water bottle in a bathtub, w, is a function of time, t. Let P represent this function. Height is measured in inches and time is in minutes.
match each statement in function with a description.
A: P(0)=0
1. after 20 minutes, the bathtub is empty
2. the bathtub starts out with no water
3. the height of the water is 4 inches
4. the height of the water is 10 inches after 4 minutes.
3. After 10 minutes, the height of the water is 4 inches
Answer:
1) P(20) = 0
2) P(0) = 0
3) P(10) = 4
4) P(4) = 10
Step-by-step explanation:
We are told that the function P(t) denotes the height of the water in the bath tub.
At P(0) = 0, it means that after 0 minutes, there is no water in the bath tub.
1) If after 20 minutes, the bathtub is empty, then we can depict the function as; P(20) = 0
2) The bath tub starts out with no water. It means at 0 minutes, there was no water in the tub. Thus;
P(0) = 0
3) If after 10 minutes, the height of the water is to be 4 inches, then;
P(10) = 4
4) If the height is 10 inches after 4 minutes, then;
P(4) = 10

Find the area of the square. Round to one decimal place.
Answer:
309.8 mm
Step-by-step explanation:
17.6 x 17.6= 309.76
309.76 rounded is 309.8
Answer:
309.8
Step-by-step explanation:
The formula for area of square is one of its sides times another (or its side squared).
So if one of the side is 17.6, it would be 17.6^2 which is 309.76.
You then round one decimal place and get 309.8

coordinate point (0,b)
Slope= -6/5
Y-Intercept = 2
Point-Slope Form:
Answer:
y - 2 = -⁶/₅xStep-by-step explanation:
The point-slope form of the equation of the line passing point (x₁, y₁) and with the slope of m is: y - y₁ = m(x - x₁)
m = -⁶/₅
Y-Intercept = 2 ⇒ point (0, 2) ⇒ x₁ = 0, y₁ = 2
