QUESTION 10
When looking at her grades, Susan found that she scored a combined 258 points on her first three tests. She also noticed that on tests two and three, she
scored 10 points fewer than the test before.
Write an equation that fits this problem.
Answer:
let the grade points be a,b,c
a+b+c=258
b=c+10( since she noticed that on tests two and three,she scored 10 points fewer).
Answer:
See belowStep-by-step explanation:
Let the first test score is x, then the next two are x - 10 and x - 20 and the total of three is 258.
We can reflect this as:
x + x - 10 + x - 20 = 258Solving we get:
3x - 30 = 2583x = 258 + 303x = 288x = 288/3x = 96The scores are: 96, 86 and 76

A car is traveling at a steady speed. It travels 2 1/2 miles in 3 1/3 minutes. How far will it travel in 29 minutes? In 1 hour?
Answer:
21.75 Miles
Step-by-step explanation:
s = d / t
d = s * t
s = 1.75 miles / 2.33333333 minutes
s = 0.75 mile/min
d = 0.75 mile/min * 29 minutes = 21.75 miles
The scale on a map says that 6cm represents 8km What is the actual number of kilometers that is represented by 8cm
If a map has a scale where 6 cm represents 8 km, using proportion, the actual distance in km that 8 cm represents is: 10.7 km.
Given the following:
Scale of map: 6 cm represents 8 kmRequired:
Actual distance that 8 cm on the map represents.
We would apply our knowledge of proportion to solve this problem as follows:
Let x represent the actual distance we are looking.
Thus, the following proportion can be made:6 cm = 8 km
8 cm = x km
Cross multiply[tex]x = \frac{8 \times 8}{6} \\\\x = 10.7 $ km[/tex]
Therefore, if a map has a scale where 6 cm represents 8 km, using proportion, the actual distance in km that 8 cm represents is: 10.7 km.

Answer:
The answer is -2.25
Answer:
-2.25
Step-by-step explanation:
1. Between each integer, there are four sections. That means that each section is 1/4, or 0.25
2. Starting at -2, we're going to the left by 0.25 to point B. This can be written as an equation of: [tex]-2 - 0.25 = B[/tex]
3. Now, since -2.25 is the result when subtracting 0.25 from -2, -2.25 is the decimal value positioned at point B.

Answer:
<1 = 58 , <2 = 122, <3 = 58
Step-by-step explanation:
concept #1: a straight line has an angle of 180.
180 -122 = 58
concept #2: a angle across from another(in which they share a common point made by two lines crossing each other) have essentially the same angle degree
<2 = 122
there <3 is also angle degree of <1 which is 58

The midpoint of \overline{\text{AB}}
AB
is M(3, -2)M(3,−2). If the coordinates of AA are (8, 4)(8,4), what are the coordinates of BB?
Answer:
Step-by-step explanation: I am trying to interpret the question: I'll assume:
Line AB has a midpoint, M.
A is (8,4)
B is unknown, but desired
M is (3,-2)
We'll assume a straight line of the form y=mx+b, where m is the slope. m can be calculated by the "Rise" over the "Run" between the points A and M:
Rise = (4-(-2))=6
Run = (8-3)=5
Slope = (Rise/Run) = (6/5)
The line becomes y=(6/5)x+b
Calculate b, the y-intercept (the value of y when x is 0), by entering one of the two known points. I'll choose (8,4).
y=(6/5)x+b
4 = (6/5)(8)+b
b = 4 - (6/5)(8)
b = 4 - (48/5)
b = 4 - (9 3/5) or -5 3/5
The equation becomes:
y=(6/5)x - 5 3/5
Point B will have an x value of -2 [The change in x from A to M was (3-8) = -5. From M to 5 would be another -5 increment, so x goes from 3 to (3-5) or -2.
Find the value of y for x=-2:
y=(6/5)x - 5 3/5
y=(6/5)*(-2) - 5 3/5
y=(-12/5) - (28/5)
y = -(40/5) or - 8
B has coordinates of (-2, -8)
If coordinates of point A is (8, 4), then the coordinate of point B will be (-2, -8).
The "Midpoint-Formula" is used to find the coordinates of a point that lies exactly halfway between two given points. It's given as :Midpoint (M) = ((x₁ + x₂)/2, (y₁ + y₂)/2),
In this case, we have the midpoint as M(3, -2) and one of the endpoints as A(8, 4). We need to find coordinates of other endpoint which is B,
Using the midpoint formula, we rearrange it to solve for the missing coordinates (x₂, y₂),
x₂ = 2 × Mₓ - x₁,
y₂ = 2 × [tex]M_{y}[/tex] - y₁,
Substitute the given values:
We have : Mₓ = 3; [tex]M_{y}[/tex] = -2,
x₁ = 8; y₁ = 4
x₂ = 2 × 3 - 8 = -2; y₂ = 2 × -2 - 4 = -8,
Therefore, the coordinates of point-B is(-2, -8).

9514 1404 393
Answer:
3:10 p.m.
Step-by-step explanation:
The amount that will have leaked is ...
1200 mL -450 mL = 750 mL
The time required for this amount to leak out is ...
(750 mL)/(3 mL/min) = 250 min = 4 h, 10 min
There will be 450 mL left in the carton at 3:10 p.m.
