A chemist needs to mix 6 parts acid to 7 parts base for a reaction. If they need a total of 52mL (milliliters) of reaction, how many mL
of acid and base are needed?
Answer:
24 millilitres acid
28 millilitres base
Step-by-step explanation:
First, we need to know how many parts there are in total. We do this by adding the number of parts of acid (6) and base (7). 6+7=13
Then, divide 52 by 13 to find out how many millilitres makes up a part.
52/13=4
Then you multiply this by the number of parts for each substance.
4x6=24 millilitres acid
4x7=28 millitres base

The difference quotient is used to determine the average rate of change of g(x) = 5x2 + 6x on the interval from x = 1 to x = 5. Which statement describes the process correctly?
Answer:
C. The difference quotient is 10x+5h +6, so the average rate of change is 10(1)+ 5(4) + 6 = 36
Step-by-step explanation:
The statement is the difference quotient is 10x+5h +6.
What is average rate of change of function?It is a measure of how much the function changed per unit, on average, over that interval. It is derived from the slope of the straight line connecting the interval's endpoints on the function's graph.
Given function:
g(x) = 5x² + 6x
interval is x= 1 to x=5
so, the average rate of change is
=10(1)+ 5(4) + 6
= 36

You spin a spinner numbered from 1 to 8 twice. Find the probability of getting a 1 on the first spin and a 2 on the second spin.
Answer:
[tex]Probability = \frac{1}{64}[/tex]
Step-by-step explanation:
The sample space of the spinner is:
[tex]Sample\ Space = \{1,2,3,4,5,6,7,8\}[/tex]
So:
[tex]n(S)= 8[/tex]
All of which have the same probability.
Required
Determine the probability of 1, then 2 when spin twice
The probability of the first being 1 is:
[tex]P(1)= n(1)/n(S)[/tex]
[tex]P(1)= 1/8[/tex]
The probability of the second being 2 is:
[tex]P(2)= n(2)/n(S)[/tex]
[tex]P(2)= 1/8[/tex]
So, the required probability is:
[tex]Probability = P(1) * P(2)[/tex]
[tex]Probability =1/8* 1/8[/tex]
[tex]Probability = \frac{1}{64}[/tex]

Cynthia Besch wants to buy a rug for a room that is 19 ft wide and 25 ft long. She wants to leave a uniform strip of floor around the rug. She can
afford to buy 315 square feet of carpeting What dimensions should the rug have?
Answer:
13 x 158
Step-by-step explanation:
L= 2W
A= 315 sq ft^2
A= L*W
315= 2W* W
315/2= 158 = w^2
W^2= 158
W=[tex]\sqrt{158}[/tex]
W= 13
The rug should have a dimension of 15 ft wide and 21 ft long.
What is a rectangle?A Rectangle is a four sided-polygon, having all the internal angles equal to 90 degrees. The two sides at each corner or vertex, meet at right angles.
Let the length of the room be l and h be the width.
So, given that,
l = 19 ft
h = 25 ft
Let w be the width of rug,
Since Cynthia can afford to buy 315 square feet of carpeting
So, area of the rug should be given as,
l*h = 315
Now to carpet the room along its dimension, each side of the width is
w + w = 2w.
So, l =25 - 2w
h = 19 - 2w
Now, ∵ l*h = 315
Put the values we get,
(25 - 2w)*(19 - 2w) = 315
expanding we get,
4w² - 88w + 475 = 315
or, 4w² - 88w + 160 = 0
or, w² - 22w + 40 = 0
using the quadratic equation we get two solutions:
w = 2
w = 20
Since, w = 20 is greater than one of the width of the room i.e 19ft
So,we take the solution w = 2
Thus, dimensions of rug is given as,
l = 25 - 2*2 = 21 ft
h = 19 - 2*2 = 15 ft
Thus, the rug should have a dimension of 15 ft wide and 21 ft long.

i honestly forgot how to solve this
Answer:
c must be -4
Step-by-step explanation:
x^2 - 5x + c = 0 is a quadratic whose coefficients are a = 1, b = -5 and c = c.
The discriminant is b^2 - 4ac, and we know that b^2 - 4ac = 41.
Substituting -5 for b and 1 for a, we get:
(-b)^2 - 4(1)(c) = 41, or 25 - 4c = 41, or -4c = 16. Thus, c must be -4, and the quadratic is
x^2 - 5x - 4

Jan walks 2 miles at a constant rate of 3 miles per hour and then runs 1 mile at a constant rate of 8 miles per hour.
(a) What is Jan’s average speed for the entire trip?
(b) Is the average speed in part (a) equal to the average of Jan’s two speeds?
Answer:
(a).4.36 mph
(b) No
Step-by-step explanation:
We are given that
Jan covered distance,s1 =2 miles
Speed of Jan, a=3 mph
s2=1 mile
b=8mph
a.
We have to find the Jan' s average speed for the entire trip.
Average speed =[tex]\frac{2ab}{a+b}[/tex]
Using the formula
Average speed=[tex]\frac{2(3)(8)}{3+8}=4.36mph[/tex]
b.
Average speed with two speed
Average of Jan’s two speeds
[tex]=\frac{a+b}{2}[/tex]
=[tex]\frac{3+8}{2}=5.5 mph[/tex]
[tex]4.36\neq 5.5[/tex]
Hence, the average speed in part (a) is not equal to the average of Jan’s two speeds.
