If a person run 1.3 miles in 10 minutes, how far can he run in 2.5 hours?
Answer:
23.4m
Step-by-step explanation:
1 hour = 60 min
2.5 hours = 180 min
180 ÷ 10 =18
18 × 1.3 = 23.4
Dan’s school is planning a field trip to an art museum. Bus company A charges a $60 rental fee plus $4 per student Bus company B charges $150 plus $2 per student. How many students would have to go for the cost to be the same?
Answer: 45 students
Step-by-step explanation:
Company A’s charge can be represented by: 4s+60
Company B’s charge can be represented by: 2s+150
s is the charge per student
To find the cost at which they are the same, I will set both equations equal to each other.
4s+60=2s+150
-2s -2s
2s+60=150
-60 -60
2s=90 Divide both sides by 2
s=45
So when 45 students are going, the cost for both companies are the same.

Solve the equation
2(x+5)=-2
Answer:
x = -6
Step-by-step explanation:
Distribute the 2 into the brackets:
2x + 10 = -2
leave the 2x alone on one side:
2x = -2 -10
2x = -12
divide both sides by 2:
x = -6

Answer:
a = 60
60°, 60°, 120°, and 120°
Step-by-step explanation:
So we know that the sum of the angle measures of the quadrilateral is 360° and that the four angle measures are a, 2a, a, and 2a. This means that the sum of a, 2a, a, and 2a should equal 360.
a + 2a + a + 2a = 360
Combine like terms.
6a = 360
Divide both sides by 6.
a = 60
So the value of a would be 60.
Now to find the angle measures from least to greatest, we would have to find the values of a, 2a, a, and 2a.
a = 60
2a = 120
a = 60
2a = 120
So the angle measures from least to greatest is 60°, 60°, 120°, and 120°.
I hope you find my answer and explanation to be helpful. Happy studying.
Answer:
a=60 degrees
Step-by-step explanation:
Total angle measurements=360 so
2a+2a+a+a=360
2(60)+2(60)=240
240+60+60=360
----------------------------
So a=60

State if each triangle is acute, obtuse, or right.
2)

14 ft
197 ft
B) Acute
A) Right
C) Obtuse
Hi!
Your answers should be : 1. Obtuse | 2. Acute | 3. Obtuse
Here's a little tip for you to remember if you cant get an answer off of brainly: if its 90ft (or degrees or what ever you want to call it) then its right, if its over 90ft its Obtuse, and if its under 90ft its Acute.
Hope this helps!

Given A(-1,4), B(2,-5), and C(3, 4), which coordinate pair will make AB perpendicular to CD ?
Answer:
The coordinate pair of the point D that will make AB perpendicular to CD is the D(6, 3)
Step-by-step explanation:
The slope of the given line AB can be presented as follows;
[tex]Slope, \, m =\dfrac{y_{2}-y_{1}}{x_{2}-x_{1}}[/tex]
[tex]m =\dfrac{-5-4}{2-(-1)} = \dfrac{-9}{3} =-3[/tex]
The slope of a perpendicular line to a given line is equal to the negative reciprocal of the slope of the given line
Therefore, the slope of the perpendicular to a line that has a slope of m is -1/m
The slope of the perpendicular to the line AB is therefore [tex]-\dfrac{1}{3}[/tex]
From which we get the equation of the perpendicular to the line AB given as follows;
y - 4 = -1/3 × (x - 3)
y - 4 = -x/3 + 1
y = -x/3 + 1 + 4
y = -x/3 + 5
When x = 6, y = -6/3 + 5 = 3
Therefore, the coordinate pair of the point D that will make AB perpendicular to CD is the D(6, 3).
Using the slope concept, it is found that the coordinate pair is:
[tex]D\left(x, \frac{x}{3}+9\right)[/tex]
The slope of a coordinate pair [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex] is given by the change in y divided by the change in x, that is:
[tex]m = \frac{y_2 - y_1}{x_2 - x_1}[/tex]
If two segments are perpendicular, the multiplication of their slopes is -1.
For segment AB, the slope is:
[tex]m = \frac{-5 - 4}{2 - (-1)} = -\frac{9}{3} = -3[/tex]
At segment CD, we want that:
[tex]-3m = -1[/tex]
[tex]m = \frac{1}{3}[/tex]
Considering D(x,y), we have that:
[tex]\frac{y - 4}{x - 3} = \frac{1}{3}[/tex]
Writing y as a function of x:
[tex]x - 3 = 3(y - 4)[/tex]
[tex]3y - 12 = x - 3[/tex]
[tex]3y = x + 9[/tex]
[tex]y = \frac{x}{3} + 9[/tex]
Thus, the coordinate pair is:
[tex]D\left(x, \frac{x}{3}+9\right)[/tex]

2) yes, positive plus negative can be negative if the negative is bigger than the positive ex.(5-15=-10
3) yes, negative plus negative is negative

When the table says that there has been a RISE, that means that you should ADD. When the table says there has been a FALL, that means you should SUBTRACT.
The second row and the second column is saying a RISE, meaning that you should ADD 8 and 2. 8 + 2 = 10. So the answer for that one would be 10 degrees celcius (third column, second row.) The numbers in bold are your equation for the second row and fourth column.
Here are the rest: AT MEANS AFTERNOON TEMPERATURE :)
3rd row: AT = -8 [degrees celcius] EQUATION: -2 - 6 = -8
4th row: AT = 3 [degrees celcius] EQUATION: -4 + 7 = 3
5th row: AT = -3 [degrees celcius] EQUATION: 6 - 9 = -3
6th row: AT = -10 [degrees celcius] EQUATION: -5 - 5 = -10
7th row: AT = 0 [degrees celcius] EQUATION: 7 - 7 = 0
Woohoo! We're done with that part now.
(b) So, as I said before, a RISE means you must ADD. If you have a rise in -7 degrees celcius, how would you write that mathematically? You would write it like this: + ( - 7 ). You are ADDING NEGATIVE SEVEN. I know it sounds weird, but it is what it is. NOW. Adding negative 7 IS THE EQUIVALENT of saying subtract seven. Here's an example:
10 + ( - 7 ) = 3 (this is true)
10 - 7 = 3 (this is also true)
Therefore, for b you would say that you agree because +(-7) is the equivalent of say 'minus 7'.
Hopefully, you can use what I explained to help you with number 2. If you need more help you can just comment on this post and I'll help you. :))

How many boys are there in a group of 27 students if there are four-fifths as many girls as there are boys?
Answer:
15 boys
Step-by-step explanation:
There are 27 students. The number of girls is only 4/5 of the number of boys. I started by splitting the class. 14 boys and 13 girls doesn't work, so I changed it to 12 and 15. If it was 12 girls and 15 boys, the girls would have 4/5 of the boys, so it must be 12 girls and 15 boys.
