Answer:
10
Step-by-step explanation:
Miguel will circle 10 counters because 5/8 * 16 = 10.
Answer:
A. 10 is the correct answer.
Step-by-step explanation:
The equation is 5/8 x 16.
Here, there are 16 counters. This is also known as 2 rounds of 8, which is the denominator in our fraction. Since 8 is 1/2 times 16, 5 x 2, or 10, is the correct answer.
Hope this helps! :)
It costs $5.50 per hour to rent a pair of ice skates for the first 2 hours. After 2 hours, the rental cost decreases to $2.50 per hour. Using the table you created for the last problem, calculate the cost to rent a pair of ice skates for 4 hours.
Answer: It would cost $16 dollars for 4hrs
Step-by-step explanation:
1. First find the value of the first two hours so $5.50+$5.50=$11
2. Then calculate how much for the last two hours, so $2.50+$2.50=$5
3. Combine the two $11+$5=$16 for 4hrs

What is the length of JN? Please help!
Answer:
Answer is 6 and 2/3. That’s it
Step-by-step explanation:
The length of JN of the second triangle is [tex]6\frac{2}{3}[/tex].
Triangle SimilarityWhat is similarity of triangles?If two triangles have an equal number of corresponding sides and an equal number of corresponding angles, then they are comparable.
Similar figures are described as items with the same shape but varying sizes, such as two or more figures.
Calculation for the length JN:As the two triangles BTL and PJN are similar because the corresponding two angles are given equal in the question.
Thus, the ratios of the side are equal.
[tex]\frac{BT}{JP} = \frac{LT}{JN}[/tex]
[tex]\frac{6}{8} =\frac{5}{JN}[/tex]
[tex]JN =\frac{20}{3}[/tex]
[tex]JN= 6\frac{2}{3}[/tex]
Therefore, the length JN of the triangle comes out to be [tex]6\frac{2}{3}[/tex].

In ∆ABC A= 50°. B = 70° , then B =________
(A) 120° (B) 60° (C) 50 (D) 709
Answer:
(B) 60°
Step-by-step explanation:
The total sum of angles in a triangle is 180°. Since you already know the first 2 angles, you can find the last angle C.
C = 180° - 50° - 70°
= 60°

The ratio of the ages (in years) of two teachers is 8:9. The sum of their ages is 51. What is the age of each teachers?
Answer:
x = 24yrs and y = 27yrs
Step-by-step explanation:
Let the age of one of the teachers be x
Let the age of the other teacher be y
From the second sentence;
x + y = 51 ----------(1)
From the first sentence;
x/y = 8/9 ------------(2)
Making y the subject of formula in equation (1) as follows;
y = 51 -x -------------(3)
Substitute (3) into (2) as follows;
x/51- x = 8/9
Cross multiply as follows:
9*x = 8(51- x)
9x = 408 - 8x
Collecting like terms;
9x + 8x = 408
17x = 408
Divide both sides by 17;
x = 24 yrs
Substitute x = 24 into equation (3) as follows;
y = 51 - 24
y = 27 yrs
why the law of contract has seen so little constitutional transformation?
Answer:
Because the law of contract has to do with private law relation.
Step-by-step explanation:
Given that law of contract has to deal with Private laws involving parties to the contract, but not in any way affecting or involving the state or society. The law of contract has seen so little constitutional transformation. For example law of the contract between manufacturers of cars and consumers or buyers.
This is evident in the fact that people's perception and the reality is that the outcomes of the successful delivery or breach of the law of contract have no direct implication on the other people in the society such as individual rights.

Step-by-step explanation:
Find the coordinates of the midpoint for the line with endpoints; A(-1, 5) and B(2, -3). Use the midpoint formula.
Answer:
(0.5, 1)
Step-by-step explanation:
The midpoint formula says that the midpoint between two points (a, b) and (c, d) is:
[tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]
Here, a = -1, b = 5, c = 2, and d = -3, so the midpoint is:
[tex](\frac{a+c}{2},\frac{b+d}{2})[/tex]
[tex](\frac{-1+2}{2},\frac{5-3}{2})=(\frac{1}{2} ,\frac{2}{2} )=(0.5,1)[/tex]
The answer is thus (0.5, 1).

use the substitution method to solve the system of equations.
x+y=11
-x=-y-9
Like you said, we need to use substitution to solve for y.
[tex]x + y = 11\\-1(-x = -y - 9)\\\\x + y = 11\\x = y + 9\\\\y + 9 + y = 11\\\\2y + 9 = 11\\\\2y = 20\\\\y = 10[/tex]
Now that we've solved for y, we can plug in the number we got into one of the original equations. (You can choose either equation, but I will use the first one.)
[tex]x + 10 = 11\\\\x = 1[/tex]
Now we have the solution of this system.

The table below gives the age and bone density for five randomly selected women. Using this data, consider the equation of the regression line, yˆ=b0+b1x, for predicting a woman's bone density based on her age. Keep in mind, the correlation coefficient may or may not be statistically significant for the data given. Remember, in practice, it would not be appropriate to use the regression line to make a prediction if the correlation coefficient is not statistically significant.
Age 36 39 48 53 58
Bone Density 358 351 330 325 314
Table
Step 1 of 6 : Find the estimated slope. Round your answer to three decimal places.
Answer:
-1.973
Step-by-step explanation:
Given the data :
Age 36 39 48 53 58
Bone Density 358 351 330 325 314
Equation of regression line is in the form:
yˆ=b0+b1x
Where y = predicted variable ;
b0 = intercept ; b1 = slope or gradient ; x = predictor variable
Using The correlation Coefficient calculator :
The regression equation obtained is :
ŷ = -1.97316X + 427.94399
From the equation ;
The slope or gradient (b1) = - 1.97316
Hence, estimated slope to 3 decimal places is : - 1.973
