Where is the blue dot on the number line?
Answer:
where is the picture and can you answer the questions on my page for points
Answer: Where is the number line or the blue dot?
Answer this CORRECTLY! The question will be placed first, I'll place the graphs and in order from A - D, then I want to see what you can do. 100 Points Sounds Nice....
Answer:
Option D
Step-by-step explanation:
x-axis is the Celsius and
y-axis is the Farenheit
If you look at the points in the table, you will notice that the only graph that contains points (0,32), (10,50), (15,59) is option D. You can assume point (30,86) will also be in the graph by looking at the way the line is going.
This is the same as graphing a line with a point (x,y).

a) 1.0 mile
b) 5.0 mile
c) 5.8 mile
d) 0.8 mile
Answer:
d) 0.8 mile
Step-by-step explanation:
Coordinate of object B = (6, 6)
Coordinate of object C = (1, 4)
Coordinate of the archaeologist = (6, 1)
✍️Distance between Object B (6, 6) and the archaeologist (6, 1):
Distance = |6 - 1| = 5 units = 5 miles
✍️Distance between Object C (1, 4) and the archaeologist (6, 1):
Using the distance formula, [tex] d = \sqrt{(x_2 - x_1)^2 + (y_2 - y_1)^2} [/tex], we would have:
[tex] d = \sqrt{(6 - 1)^2 + (1 - 4)^2} [/tex]
[tex] d = \sqrt{(5)^2 + (-3)^2} [/tex]
[tex] d = \sqrt{25 + 9} [/tex]
[tex] d = \sqrt{34} = 5.8 units = 5.8 miles [/tex] (nearest tenth)
Comparing how far each object is from the archaeologist, object C is 0.8 mile (5.8 - 5 = 0.8) farther than object B.

The length of a rectangle is the same as the length of each side of a square.
The length of the rectangle is 4 cm more than 3 times the width of the rectangle.
The area of the square is 66 cm? more than the area of the rectangle.
Find the length and the width of the rectangle.
You must show all your working.
I searched your question and here is what I found:
Step-by-step explanation:
L = 4 + 3W (from the second condition)
L2 = 66 + LW (combining the first and third condition)
L2 = 66 + L(L-4)/3
3L2 = 198 + L2 -4L
2L2 + 4L -198 = 0
(2L - 18)(L + 11) = 0; discarding the negative root for lack of practicality , L = 9
from the first equation W = (L - 4)/3 = 5/3 = 1 2/3; 1.67
Hence the length of the rectangle is 9 cm and the width is 1.67 cm
check;
2nd condition; L = 4 + 3*1.67 = 9 (proven)
1st and 3rd condition; 92 = 66 + 9*1.67 = 81 (proven)
The length of the rectangle is 9 cm.
The width of the rectangle is 5/3 cm.
What is a rectangle?A rectangle is a two-dimensional shape where the length and width are different.
The area of a rectangle is given as:
Area = Length x width
We have,
Rectangle:
Length = 3w + 4
Width = w
Area = (3w + 4)w
Square:
Side = 3w + 4
Area = (3w + 4)²
Now,
The area of the square is 66 more than the area of the rectangle.
This means,
(3w + 4)² = (3w + 4)w + 66
9w² + 16 + 24w = 3w² + 4w + 66
9w² - 3w² + 24w - 4w + 16 - 66 = 0
6w² + 20w - 50 = 0
2 (3w² + 10w - 25) = 0
3w² + 10w - 25 = 0
3w² + (15 - 5)w - 25 = 0
3w² + 15w - 5w - 25 = 0
3w(w + 5) - 5(w + 5) = 0
(3w - 5)(w + 5) = 0
w + 5 = 0 and 3w - 5 = 0
w + 5 = 0
w = -5 (rejected since its negative)
3w - 5 = 0
3w = 5
w = 5/3
Now,
Length.
= 3w + 4
= 3 x 5/3 + 4
= 5 + 4
= 9
Width = 5/3
Thus,
The length and width of the rectangle are 9 and 5/3.

Explain why when dividing fractions with the same denominator, you can find the quotient by dividing the numerators. Support your answer with an example using one or more mixed numbers.
By dividing fractions with the same denominator, you can find the quotient as the same as numerators.
To explain when dividing fractions with the same denominator, you can find the quotient to as the same as the numerators.
Here,
Let's assume a fraction a / b
While dividing the fraction a / b with the fraction with the same denominator 1 / b,
= a / b ÷ 1 / b
While dividing the fraction by another fraction then the result shows the fraction as multiplication of the numerator of one fraction with the denominator of another fraction over the multiplication of the denominator of one fraction with the numerator of another fraction.
= a / b * b / 1
= a
Thus, by dividing fractions with the same denominator, you can find the quotient as the same as numerators.

A researcher wants to know if eating a mint affects whether people can distinguish between two popular orange juice brands. To conduct an experiment, the researcher places participants in two groups. The treatment group will eat a mint before drinking a juice, while the control group will not eat a mint before drinking. Then the participants will guess the juice brand.
Randomization is important when assigning the participants to the treatment and control groups to ensure
that there will be the same number of participants in both groups.
that the experiment results can be generalized to all people.
that both groups have participants that like both popular juice brands.
that both groups are roughly equivalent with regards to demographics and juice preferences.
Answer:
D
Step-by-step explanation:
Just took the quiz trust me
Randomization helps to eliminate the effect of sampling bias in an experiment. Therefore, random assignment of participants ensures equivalence in terms of the demographic and juice preference.
When subjects are randomly assigned to the groups, it eliminates the possible bias which may arise from personal preference which subjects have for a particular juice and which may yield a trend which isn't as a reflection of the actual study.
Therefore, the elimination of bias as a result of random assignment helps to strike a balance between the treatment and control samples regarding preference.

Answer: 1.25 p , where p= Weight of Jordan's dog
Step-by-step explanation:
Let p = Weight of Jordan's dog .
Given: Emmett apostrophe's dog with 25% more than Jordan star.
Then, weight (in pounds) of Emmett apostrophe s dog = p +25% of p
= p +0.25 p [We divide a number by 100 to remove %]
= p(1+0.25)
= p(1.25)
=1.25 p
Hence, the expression represents the weight in pounds of Emmett apostrophe's dog=1.25 p
