Answer: 18
Explanation: 18 times 2.5 is 45. 45 +18=63
Answer:
the answer would be 25 because to get the answer you would take 63 and divide it by 2.5 and you will get 25.2 then rounding it to the nearest 10th would be 25
then after you get 25 you would put it into the equation 2.5(x) = 63 which would be 2.5(25)=63. that it y 25 would be the correct answer.

David rode his bike a total of 214 miles from his house to the store. First he rode 34 mile from his house to his school. Then he rode 14 mile from his school to the library. Finally he rode from the library to the store. How many miles did David ride between the library and the store?
Answer:
166 miles
Step-by-step explanation:
Add the 34 miles he rode from home to school and the 14 miles he rode from school to the library.
34 + 14 = 48.
Subtract 48 from 214 to get 166
214 - 48 = 166
David rode 166 miles between the library and the store.

b is NOT equivalent, because the content of parentheses is evaluated first. That makes the expression equal to 2/15, which is not equal to the given expression.

Answer:
A: 8 ft²
B: draw diagonal AC; 4 ft²
Step-by-step explanation:
Part A: The area is given by the formula ...
A = bh . . . . . . . the product of base and height dimensions
A = (9 ft)(8/9 ft) = 8 ft² . . . . area of the parallelogram
__
Part B:
Either diagonal (AC or BD) will divide the parallelogram into two congruent triangles, each with the same base and height as the parallelogram. It is no surprise, then, that the area of either of those triangles is ...
A = 1/2bh
A = 1/2(9 ft)(8/9 ft) = 4 ft² . . . . . . area of triangular half of parallelogram
__
AC divides the figure into congruent acute triangles; BD divides it into congruent obtuse triangles.

Answer:
In the first one you are missing (a +7) so it's going to be 9(a +7) or when you factor that out it will be 9a 63
In the other one you are missing the (a +5) so it's going to be 7a(a + 5) or when you factor it out it will be 7a2 + 35a
Step-by-step explanation:
a2+ 9a + 20 = (a + 4) (a + 5)
a2 + 11a+ 28 = ( a + 7) ( a + 4 )

Three runners competed in a race data were collected at each mile mark for each runner If the runner ran at a constant paste the data would be linear a regression line was fitted to their data Use the residual plots to decide which data set is best fit by regression line and then identify the runner that kept the most consistent pace
Answer:
Runner C
Step-by-step explanation:
Tell me if I'm wrong but 100% sure I'm right
The linear regression for the best fit of the data to identify the runner that kept the most consistent pace is Runner C
What is linear regression line?The connection between the independent (x) and dependent (y) variables in the graph can be graphically represented using regression lines.
In a linear model, the terms are added rather than multiplied, divided, or provided as a non-algebraic function, as has been the case thus far in this section. Analysis of experimental, monetary, and biological data as well as complex system prediction are both possible using linear modelling.
A statistical technique used to build a linear model is called linear regression. The model explains how one or more independent variables Xi relate to a dependent variable y (also known as the response) (called the predictors). The distance between each data point and the regression line is called a residual.
Given data ,
Three runners competed in a race data were collected at each mile mark for each runner
And , If the runner ran at a constant paste the data would be linear
Now , a linear a regression line was fitted to their data
And , In linear regression, consistent data refers to a set of data points that fall in a linear pattern with a small amount of scatter around the line of best fit. The data is said to be consistent if the residuals (the vertical distances between the observed data points and the predicted values on the line of best fit) are relatively small and do not exhibit any patterns or trends.
So , the runner C has the most consistent pace among the three runners
Hence , runner C is the best fit for the regression line

Amir can run 15 kilometers in one hour. How many kilometers can Amir run per minute? There are 60 minutes in 1 hour.
The answer is .25 kilometers a minute.
This is because [tex]speed = \frac{distance}{time}[/tex] so you need substitute then divide to find the answer
You can check this answer by doing 15÷60 which comes out to .25 km a minute.
Answer:0.25m per minute
Step-by-step explanation:
You divided the 15 by the 60 since 15 is the km and 60 minutes and you want to know how far can she run in minutes

Answer:
A. x = {nπ, π/4 +nπ}
Step-by-step explanation:
The zero product rule tells you the solutions are found where the factors are zero:
tan(x) = 0 ⇒ x = nπ
tan(x) -1 = 0 ⇒ x = arctan(1) +nπ = π/4 +nπ

Answer:
domain: x ∉ {-4, 3}range: y ∉ {1}horizontal asymptote: y=1vertical asymptote: x=3Step-by-step explanation:
The expression reduces to ...
[tex]\dfrac{x^2+9x+20}{x^2+x-12}=\dfrac{(x+4)(x+5)}{(x+4)(x-3)}=\dfrac{x+5}{x-3}\quad (x\ne-4)[/tex]
The domain is limited to values of x where the expression is defined. It is undefined where the denominator is zero, at x=-4 and x=3. The graph of the expression has a "hole" at x=4, where the numerator and denominator factors cancel.
the domain is all real numbers except -4 and +3The function approaches the value of 1 as x gets large in magnitude, but it cannot take on the value of 1.
the range is all real numbers except 1As discussed in 'range', there is a horizontal asymptote at y=1. That is the value you would get if you were to determine the quotient of the division:*
(x+5)/(x-3) = 1 + (8/(x-3)) . . . . quotient is 1
There is a vertical asymptote at the place where the denominator is zero in the simplified expression: x = 3.
vertical asymptote at x=3; horizontal asymptote at y=1_____
* For some rational functions, the numerator has a higher degree than the denominator. In those cases, the quotient may be some function of x. The "end behavior" of the expression will match that function. (Sometimes it is a "slant asymptote", sometimes a higher-degree polynomial.)
Which of the following is correctly written in Standard Form?

9514 1404 393
Answer:
(b) 4x- 3y = 6
Step-by-step explanation:
Standard form is ...
ax +by = c
where a, b, c are mutually prime integers and a > 0. (If a=0, then b>0.)
__
A: slope-intercept form with variables on both sides of the equal sign.
B: standard form

Janae solved the equation 3.67 = c − 2.13 , and found the value for c. Janae's solution was c =1.54 Do you agree or disagree with her solution. Explain. Show your work.
Answer:
Solution;
given equation : 3.67 = c - 2.13
On solving equation, we get
c = 3.67 +2.13
c = 5.8
Hence, Janae solution is incorrect. So I disagree.
At his birthday party, Aiden collected 15% of the candy that fell out of the piñata. If Aiden collected 6 pieces of candy, how many pieces of candy fell out of the piñata?
Answer:
40 pieces
Step-by-step explanation:
To make it easier, I'm gonna divide 15 by 3 and then multiply it by 2. Same with 6.
10% of candy = 4 pieces.
Multiply by 10
100% of candy = 40 pieces.
