Answer:
Decrease or decline in water level per day
Step-by-step explanation:
Given the question above ;
The situation which could be repress Ted by a negative number is the decrease in the water level of the pool being measured :
It could be expressed as - 1 1/2 inches per day
Fall, decrease, loss or reductions are usually modeled in mathematics using the negative sign as it portrays a negative adjustment or reduction in the original amount of a commodity, item or phenomenon.
Furthermore, total decline after 5 days will be ;
-1 1/2 * 5 = (-3/2 * 5) = - 15/2 = - 7.5 inches

Tony’s Pizzeria customers were asked what kind of pizza topping they prefer. Tony learned that 20 customers selected pepperoni, 12 selected mushrooms, and 8 selected pepperoni and mushrooms. What is the probability that a randomly selected customer selected pepperoni but not mushrooms?
A.1/2
B.2/5
C.3/5
D.3/8
Answer:
A. 1/2
Step-by-step explanation:
First, find how many customers there were:
20 + 12 + 8
= 40
20 customers selected pepperoni only, so to find the probability that they chose pepperoni but not mushrooms, divide the amount by the total:
20/40
= 1/2
So, the probability is 1/2

Which point does NOT lie on the graph of y=f−1(x)
(−4, −2)
(−1, −3)
(5, 1)
(24, 2)
Answer:
(3, - 4 )
Step-by-step explanation:
Given a point (x, y ) on the graph of y = f(x) then the corresponding point on the inverse function is (y, x ), thus
(- 4, 3 ) is a point on f(x), then
(3, - 4 ) is the corresponding point on (x)

Nicole is making tuna salad for her office colleagues. It takes 2/5 of a pound of canned tuna to make 5 portions of salad. She uses 1 1/5 pounds of canned tuna for every 2 onions used. If Nicole uses a total of 4 onions, then how many portions of salad does she make?
Answer:
30 portions of salad
Step-by-step explanation:
Given that :
2/5 pounds of canned tuna = 5 portions of salad
For every 2 onions used, 1 1/5 pounds of canned tuna is used ;
Number of onions used = 4
If 4 onions were used, number of canned tuna used is ;
4 /2 * 1 1/5
= 2 * 1 1/5
= 2 * 6/5
= 12 / 5 = 2 2/5 pounds of canned tuna
Number of Portions of salad made :
2/5 pounds = 5 portions of salad
12/5 pounds = x
2/5 * x = 12/5 * 5
2/5x = 60 /5
2/5 x = 12
x = 12 ÷ 2/5
x = 12 * 5 /2
x = 60/2
x = 30 portions of salad

Jacki evaluated the expression below. 2 cubed (3 minus 1) + 4 (8 minus 12) = 2 cubed (2) + 4 (4) = 8 (2) + 16 = 16 + 16 = 32. What was Jacki's error?
Answer:His error lies in the subtraction of 12 from 8 , he wrote 4 instead of -4 , as 8-12 gives -4 instead of 4.
Step-by-step explanation:
Step 1
Rewriting this to a mathematical expression 2 cubed (3 minus 1) + 4 (8 minus 12) and solving correctly gives
2³(3-1)+ 4(8-12)
=8(2) + 4(-4)
= 16 +(-16)
16-16=0
Step 2-----Jacki's evaluation
2³(3-1)+ 4(8-12)
= 2³(2) +4(4)
= 8(2) +16= 16+ 16 =32
His error lies in the subtraction of 12 from 8 , he wrote 4 instead of -4 , as 8-12 gives -4 instead of 4.

The scale on a map is 5cm=25miles. Kyle measured the distance from his house
to the store and it was 13cm. How many miles away is the store from Kyle's
house?
Answer:
65 cm
Step-by-step explanation:
The unit rate of the scale is 1cm=5miles
so you would multiply 13 cm by 5 miles to get 65cm
Answer:
65 miles
Step-by-step explanation:
25 divided by 5 = 5
13 x 5 = 65
In an AP. 19th term is 52 and 38th term is 128. Find the sum of the first 56 terms.
19th term of an AP = 52
38th term = 128
Find:the sum of the first 56 terms
Solution:We know that,
nth term of an AP – a(n) = a + (n - 1)d
Hence,
→ a + (19 - 1)d = 52
→ a + 18d = 52 -- equation (1)
Similarly,
→ a + (38 - 1)d = 128
→ a + 37d = 128 -- equation (2)
Subtract equation (1) from (2).
→ a + 37d - (a + 18d) = 128 - 52
→ a + 37d - a - 18d = 76
→ 19d = 76
→ d = 76/19
→ d = 4
Substitute the value of d in equation (1).
→ a + 18 * 4 = 52
→ a = 52 - 72
→ a = - 20
We know,
Sum of first n terms of an AP – S(n) = n/2 * [ 2a + (n - 1)d ]
Hence,
→ S(56) = 56/2 * [ 2 (- 20) + (56 - 1) * (4) ]
→ S(56) = 28 * [ - 40 + 55 * 4 ]
→ S(56) = 28 * [ - 40 + 220 ]
→ S(56) = 28 * (180)
→ S(56) = 5040
Hence, the sum of first 56 terms of the given AP is 5040.
I hope it will help you.
Regards.
The sum of the first 56 terms of the given AP is 5040.
What is an arithmetic progression?The sequence in which every next number is the addition of the constant quantity in the series is termed as the arithmetic progression. A number series is a number-based sequence. In the number series questions, we must identify the rules that lead to the formation of a number series.
Given that in an AP. 19th term is 52 and 38th term is 128.
nth term of an AP – a(n) = a + (n - 1)d
a + (19 - 1)d = 52
a + 18d = 52 -- equation (1)
Similarly,
a + (38 - 1)d = 128
a + 37d = 128 -- equation (2)
Subtract equation (1) from (2).
a + 37d - (a + 18d) = 128 - 52
a + 37d - a - 18d = 76
19d = 76
d = 76/19
d = 4
Substitute the value of d in equation (1).
a + 18 * 4 = 52
a = 52 - 72
a = - 20
Sum of first n terms of an AP – S(n) = n/2 * [ 2a + (n - 1)d ]
S(56) = 56/2 * [ 2 (- 20) + (56 - 1) * (4) ]
S(56) = 28 * [ - 40 + 55 * 4 ]
S(56) = 28 * [ - 40 + 220 ]
S(56) = 28 * (180)
\S(56) = 5040
Hence, the sum of the first 56 terms of the given AP is 5040.

What’s the slope?
( “M”only)
Answer:
slope (m) = [tex]\frac{5}{6}[/tex]
Step-by-step explanation:
Find the slope by using the following equation:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
([tex]x_1 , y_1[/tex]) = (1 , 2)
([tex]x_2 , y_2[/tex]) = (7 , 7)
Plug in the corresponding numbers to the corresponding variables:
slope (m) = [tex]\frac{7 - 2}{7 - 1} = \frac{5}{6}[/tex]
slope (m) = [tex]\frac{5}{6}[/tex]
~
[tex] \LARGE{ \underline{ \purple{ \bf{Required \: answer:}}}}[/tex]
We can find the slope (m) by using the formula:
[tex] \rm{m = \dfrac{y2 - y1}{x2 - x1} }[/tex]The points given to us:
(x1 , y1) = (1 , 2)(x2 , y2) = (7 , 7)Plugging the given values of x1, y1, x2 and y2 to find the slope:
[tex] \rm{m = \dfrac{7 - 2}{7 - 1} }[/tex]
This is equals to,
[tex] \rm{m = \dfrac{5}{6} }[/tex]
And this is our required result....
