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?
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
Do you have a triangle with 3 angles:60 degrees,60 degrees,and 63 degrees
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

Answer:
12.04 = BC
Step-by-step explanation:
A tangent intersects at 90 degrees
We know AB and AC
We can use the Pythagorean theorem
a^2 + b^2 = c^2
AC^2 + AB^2 = BC^2
8^2 + 9^2 = BC^2
64+ 81 = BC^2
145 = BC^2
Take the square root of each side
sqrt(145) = BC^2
12.0415945 BC
To the nearest hundredth
12.04 = BC

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.
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

60 total fourth graders and 43 are girls. To find the number of boys, subtract.
60 - 43 = 17 boys
If 5 girls were absent, subtract.
43 - 5 = 38 girls present
If 4 boys were absent, subtract.
17 - 4 = 13 boys present
Therefore, there were 13 boys present.
Best of Luck!
Answer:
13 boys were present
Step-by-step explanation:
→ In total there is 60 fourth graders at the Small Tree School.
→ 43 of them are girls and this information is given to us which means that there is 17 boys because 60 - 43 = 17
→ We want to know know how many boys were at the school on Friday considering that 5 fourth grade girls and 4 fourth grade boys were absent
→ We know that there is a total of 17 boys and 4 fourth grade boys were absent so 17 - 4 will give us the number of boys that were present on Friday so 17 - 4 = 13. 13 boys were present considering 5 fourth grade girls and 4 fourth grade boys were absent

[tex]x^{2} +\frac{b}{a} x+(\frac{b}{2 a} )^{2} = \frac{-c}{a} + (\frac{b}{2 a}) ^{2}[/tex]
Step-by-step explanation:
Step(i):-
Given quadratic equation ax² + bx + c = 0
step(ii):-
ax² + bx = -c
Step(iii):-
Dividing 'a' on both sides , we get
[tex]\frac{ax^{2} +bx }{a} = \frac{-c}{a}[/tex]
[tex]x^{2} + \frac{bx}{a} = \frac{-c}{a}[/tex]
Step(iv):-
Adding [tex](\frac{b}{2 a} )^{2}[/tex] on both sides , we get
[tex]x^{2} +\frac{b}{a} x+(\frac{b}{2 a} )^{2} = \frac{-c}{a} + (\frac{b}{2 a}) ^{2}[/tex]

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.
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

The changing speed of a car is modeled by the function S(t) = –4t + 35, where t is time in seconds. Interpret the model.
A. The car has an initial speed of 0 units and is speeding up to a speed of 35 units by 4 units per second.
B. The car has an initial speed of 4 units and is speeding up by 35 units per second.
C. The car has an initial speed of 35 units and is slowing down by 4 units per second.
D. The car has an initial speed of 35 units and is speeding up by 4 units per second.
Answer:
The car has an initial speed of 35 units and is slowing down by 4 units per second.
Step-by-step explanation:
The changing speed of a car is modeled by the function :
[tex]s(t)=-4t+35[/tex]
t is time in seconds
Initial speed means at t = 0
s(0) = 35 units
Here the change in speed is negative, it means that the car is slowing down by this rate.
So, the correct answer is : The car has an initial speed of 35 units and is slowing down by 4 units per second.
Kendle wants to play several games of laser tag. She has $35 to play g games. Each game of lazer tag costs $5. Select the equation that matches this situation.
Answer:
35 ÷ 5 = g
Step-by-step explanation:
First, you snatch her/his money to do math, then you take the $35 and look the the thing that tells you how much games cost then do 35 ÷ 5 but since you cant solve it just put 35 ÷ 5 = g , and last but not least you take Kendle's money because no lazer tag during a pandemic and run home before you get yelled at because you were at a lazer tag place and took someones money.
Answer:
35/5=g
Step-by-step explanation:

Answer:
The answer is 40
Step-by-step explanation:
The reason for this is because. . .
(-1,-4) , (3,6)
so you have count from -1 to 3 and u will get 4, because if you can put (-1,-4) and (3,6) on a graph. If you did that then u must count horizantolly from -1 to 3 since they are on the x-axis. In the end you will get 4 since 3 minus -1 is 4. Also if your counting horizantally then that's ur width.
width = 4
To find the length, it is very simple. Subrtract 6 from -4 and you will get 10. And since the y-axis is being counted vertically, that is your length.
length = 10
To find the area, u have to do width times length so in this case you have to do 4 time 10 and you will get 40.
area = 40
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?
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

1.Choose the best description for ∠1 and ∠2 in the following figure.
2. Determine whether the angles are adjacent angles, a linear pair, or vertical angles. Some pairs of angles may have more than one relationship.
THE PICTURES ARE IN ORDER THE LAST TWO ARE FOR NUMBER 2
Answer:
1 ) Adjacent angles,
2 ) See solution below
Step-by-step explanation:
Question 1. Provided ∠ 1 and ∠ 1 are near one another, they can be referred to as adjacent ∠s;
Solution; Adjacent angles
Question 2.
Angles 5, and 6 are consecutively near one another, and thus are adjacent angles,
Angles 5 and 9 are supplementary knowing that they lie on a straight angle, so that they can be best named a linear pair, provided there are only two of these angles,
Angles 5 and 8 are opposite to one another so that they are ≅, thus should be names as vertical angles
Solution;
Angle | Adjacent Angles | Linear Pair | Vertical angles
∠ 5, 6 | Check! | |
∠ 5, 9 | | Check! |
∠ 5, 8 | | | Check!
