Maya can run 18 miles in 3 hours, and she can bike 18 miles in 2 hours. When Maya biked for 3 hours and then ran for 1 hour and 30 minutes, what was her average speed?
Answers
Answer: 8
Step-by-step explanation: Speed is distance/time
18/3 = 6 miles per hour running
18/2 = 9 miles per hour biking
3 hour bike = 27 miles
1.50 hour run (0.50 because 30 minutes is half of an hour) = 9 miles
27 + 9/3 + 1.50 = 36/4.5 or 8

The CoffeeShop is creating a new blend of coffee. Coffee A sells
for $5 per pound. Coffee B sells for $9 per pound. The
Coffee Shop will mix 20 pounds of the new blend and sell it for $6
per pound. The following equations represent the problem of
keeping the cost of the blend consistent with the Ingredients.
a + b = 20
5a + 9b = 120
a = pounds of Coffee A and b = pounds of Coffee B
How many pounds of Coffee B should be used in the blend?
Answers
Let x = pounds of $12 per pound coffee
then
20-x = pounds of $9 per pound coffee
.
12x + 9(20-x) = 10(20)
12x + 180 - 9x = 200
3x + 180 = 200
3x = 20
x = 20/3
x = 6 and 2/3 pounds of $12 per pound coffee
.
Amount of $9 per pound coffee:
20-x = 20-20/3 = 60/3 - 20/3 = 40/3
or
13 and 1/3 pounds of $9 per pound coffee

If ABC ≅ DCE,
Angle B = 2x + 31 and Angle E = 7x - 24
x = [?]
Answers
Answer:
The congruence statement tells you that both angle B and angle E are equal, since the triangles are identical!
Step-by-step explanation:
We want to set the equations equal to each other.
2x+31=7x-24
We need to isolate our variable, which is X.
1. Add 24 to both sides.
New Equation: 2x+55=7x
2. Subtract 2x from both sides.
New Equation: 55=5x
3. Divide by 5 from both sides so X is alone!
New Equation: x=11

E 3/4 pounds = 6/8 and 3 packages
of 1 1/8 were purchased to the 6/8 so therefor 3 times
D All packages weigh kore than 1/2 pound since 1/2=4/8 and smallest packages was 5/8 so therefor greater than 4/8
Answer:
D and E are the correct answers
Step-by-step explanation:
A is false: The difference between the greatest and least weights is NOT 1/2.
B is false: 2/9 of the packages weigh 5/8 pounds...not 1/4.
C is false: You can clearly see there were more than 12 packages purchased.
D is true: 3/4 = 6/8 and there is 1 package that weighs 6/8 pounds 1 x 3=3 and there is a total of 3 packages that weigh 1 1/8 pounds.
E is true: 1/2=4/8 and the smallest amount is 5/8 pounds which is over 1/2 pound.

Write the equation of the line that passes through the points (−1,−6) and (−5,1). Put your answer in fully reduced point-slope form, unless it is a vertical or horizontal line.
Answers
Answer:you get two answers. y+6=-7/4(x+5) or y-1=-7/4(x+5)
Step-by-step explanation:
By the way the 7/4 is negative if you could not tell. You get this answer by finding the slope which is 1- -6/-5- -1 and get -7/4. Then you plug it into the formula y-y1=slope(x-x1). When you plug it in you should get that answer.
The equation of the line that passes through the point (-1, -6) and (-5, 1) is
y = (-7/4)x - 32/4
What is an equation of a line?The equation of a line is given by:
y = mx + c
where m is the slope of the line and c is the y-intercept.
Example:
The slope of the line y = 2x + 3 is 2.
The slope of a line that passes through (1, 2) and (2, 3) is 1.
We have,
The equation of a line is y = mx + c
Now,
(-1, -6) and (-5, 1)
Slope = m
m = (1 + 6) / (-5 + 1)
m = 7/-4
m = -7/4
Now,
(-1, -6) = (x, y)
-6 = (-7/4) x -1 + c
-6 = 7/4 + c
c = -6 - 7/4
c = (-24 - 7) / 4
c = -32/4
The equation of the line is y = (-7/4)x - 32/4
Thus,
The equation of the line is
y = (-7/4)x - 32/4

A girl measures the mass of a 8 cm3 block of sugar to be a 12.9 g. What is the density of the brown sugar. Give work.
Answers
Answer:
Density: 1.6g/cm^3
Step-by-step explanation:
Density = mass/volume
Mass: 12.9g
Volume: 8cm^3
12.9/8 = 1.6125
Rounded to tenths place.
1.6 grams/cm^3
Answer:
1.61 g/cm³
Step-by-step explanation:
Density is measured as the mass divided by the volume:
d = m / v, where d is the density, m is the mass, and v is the volume
Here, our mass is 12.9 g and our volume is 8 cm cubed, so plug these in:
d = m / c
d = 12.9 g / 8 cm³
d = 1.6125 ≈ 1.61 g/cm³
The density is 1.61 g/cm³.
write the midpoint of the segment as an order pair.
Answers
Answer:
1. (3, 5)
2. (1/2, 4)
Step-by-step explanation:
To find the coordinates of the midpoint of a segment, find the average of the x-coordinates of the endpoints and the average of the y-coordinates of the endpoints.
1. (1, 2) and (5, 8)
x-coordinate of midpoint = (1 + 5)/2 = 6/2 = 3
y-coordinate of midpoint = (2 + 8)/2 = 10/2 = 5
Midpoint: (3, 5)
2. (0, 1) and (1, 7)
x-coordinate of midpoint = (0 + 1)/2 = 1/2
y-coordinate of midpoint = (1 + 7)/2 = 8/2 = 4
Midpoint: (1/2, 4)
The graph shows the numbers of quarts of yellow paint that must be mixed with different numbers of quarts of red paint to make a certain shade of orange paint.
Based on the graph, write an equation that shows the relationship between the number of quarts of yellow paint, y, and the number of quarts of red paint, x, needed to make the shade of orange paint.
Enter your equation in the space provided. Enter only your equation.
Answers
Answer:
y = 0.4x
Step-by-step explanation:
The graph shows that the relation is linear, so we can model this relation with a linear equation:
y = ax + b
To find the value of the parameters, we should get two points from the line and use their coordinates in the equation.
From point (0,0), we have:
0 = a*0 + b
b = 0
From point (2,5), we have:
2 = 5a + b
a = 2/5 = 0.4
So the equation we want is:
y = 0.4x
Do you have a triangle with 3 angles:60 degrees,60 degrees,and 63 degrees
Answers
Answer:
No
Step-by-step explanation:
The sum of all angles in a triangle is 180°. Because 60 + 60 + 63 = 183 ≠ 180, this is not a triangle.
The sum of all angles in triangle is equeal to 180°
We need to check sum of 60, 60 and 63.
60+60+63=183
183≠180
There is no such triangle
