Katherine is conducting an experiment with bacteria where she cools the temperature of one bacteria to -51°C and the other bacteria to -76°C. What was the temperature difference in the two experiments?
Answer:
Difference in temperature = 25°C
Step-by-step explanation:
Given:
Temperature 1 = -51°C
Temperature 2 = -76°C
Find:
Difference in temperature
Computation:
Difference in temperature = Temperature 1 - Temperature 2
Difference in temperature = -51°C - [-76°C]
Difference in temperature = -51°C + 76°C
Difference in temperature = 25°C

The parallelogram is shown below I have an area of 135 units. Find the missing base
Answer:
9
Step-by-step explanation:
The area of a parallelogram is base * height.
The area is given as 135
The height is given as 15
You do not need to use 17
Area = base * height Substitute
135 = base * 15 Divide by 15 on both sides
135/15 = base*15/15
base = 9
What is the Y and x intercept of 9X-6Y= 72
Answer: The y-intercept is -12
The x-intercept is 8
Step-by-step explanation: Factor out 3
Divide all by 3 to simplify.
9x - 6y = 72 is equivalent to
3x - 2y = 24
At this point, you can substitute 0 for x and solve for y
3(0) -2y = 24. -2y/-2 = 24/-2
y = -12
And substitute 0 for y and solve for x.
3x -2(0) = 24. 3x/3 = 24/3
x = 8
OR Change to slope intercept form:
y = mx + b. b is the y intercept.
-2y = -3x + 24. Solve for y.
Divide all by-2
y = 3x/2 - 12.
The y-intercept is -12
To find the x-intercept, substitute 0 for y and solve for x.
0 = 3x/2 -12 Add 12 to both sides.
12 = 3x/2. Multiply both sides by 2/3
8 = x
The x-intercept is 8
Select the slope-intercept form of an equation for a line with y-intercept -2 and slope 6.
Answer:
y = 6x - 2
Step-by-step explanation:
slope intercept form is y = mx + b
m = slope
b = y-intercept
They give us the slope (m) which is 6 and the y-intercept (b) which is -2. PLug it into the equation
y = mx + b
y = 6x - 2

Joseph’s lunch at the diner costs $15 without tax. He left the waiter a 21% tip. What was his total cost of the lunch, including tip, without tax?
Answer:
18.15
Step-by-step explanation:
21% of 15 is 3.15 so 15 plus 3.15 = 18.15

1. The Sharks Aquatic Club recently held a fundraiser to raise money for a local charity. The swimmers received money for each lap that they swam during a one-week period. The three swimmers who raised the most money were Rita, John, and Rodell. Together they swam a total of 2125 laps. John swam three times as many laps as Rita, and Rodell swam 25 more laps than John. How many laps did each swimmer swim?
Answer:
Rita = 300
John = 900
Rodell = 925
Step-by-step explanation:
rita = x (let
john = 3x ( john swims three times more than rita
rodell = 25 + 3x ( rodell swims 25 more than john
x + 3x + 25 + 3x = 2125
or, 7x + 25 = 2125
or, 7x = 2125 - 25
or, x = 2100/7
x = 300
hence,
x = 300
3x = 3 × 300
= 900
25 + 3x = 25 + 900
= 925

Josiah want to gp to the movies with his friends. Tickets are $8.50 plus he must play Fangalingo a $3 transaction fee for purchasing the tickets online. Write an equation that represents the number of tickets that Josiah can buy with $45.50
Answer:
The equation that represents the number of tickets that Josiah can buy with $45.50
3 + 8.50x = 45.50
The number of number of tickets that Josiah can buy with $45.50 is 5 ticketa
Step-by-step explanation:
Let the number of tickets be represented by x
Tickets are $8.50 plus he must play Fangalingo a $3 transaction fee for purchasing the tickets online.
The equation that represents the number of tickets that Josiah can buy with $45.50
$3 + $8.50 × x = $45.50
3 + 8.50x = 45.50
Solving further for x
3 + 8.50x = 45.50
8.50x = 45.50 - 3
8.50x = 42.50
x = 42.50/8.50
x = 5
Hence, the number of number of tickets that Josiah can buy with $45.50 is 5 ticketa

What is y= 4/5x+2 written in standard form?
Answer:
[tex]-\frac{4}{5}[/tex]x + y = 2
Step-by-step explanation:
Standard Form: Ax + Bx = C
y = [tex]\frac{4}{5}[/tex]x + 2
[tex]-\frac{4}{5}[/tex]x + y = 2
Answer:
4/5x-y=-2
Step-by-step explanation:
standard form
Ax+By=C.
y= 4/5x+2
subtract 4/5x from both sides
-4/5x+y=2
multiply both sides by negative 1
4/5x-y=-2

Answer:
x = 3 and 1/3
Step-by-step explanation:
First, get the interior angle of the 114 by subtracting 114 from 180, and you should get 66. Next, add the two known interior angles of 66 and 64 to get 130. With the knowledge that the 3 interior of all triangles add up to 180, you should know that 3x-40 is equal to 180 -130, or 50. With 3x+40 = 50, start by subtracting 40 from both sides for 3x = 10. Finally, divide both sides by 3 to get x = 3 and 1/3
b) The sum of the ages of the father and son is 44 years. After 8 years, the age of
father will be twice the age of the son. Find their present ages,
Let the present age of father = x years
and the present age of son = y years
according to the first condition
x + y =44 ........(i)
according to the second condition
x+8 = 2(y+8)
or x+ 8 = 2y + 16
or x- 2y = 8 ............(ii)
solve the equation (i) & (ii) we get
x + y =44
x- 2y = 8
••••••••••••••••••••••••
3y = 36
or y = 12
put the value of y in equation (i), we get
x + 12 =44
or x = 32
so the present age of father = x =32 years
and the present age of son = y = 12 years.
