Answer:
16.08
Step-by-step explanation:
IF Alberts bank account decreased by a total of 193 over a period of 12 days, then;
193 = 12days
To determine the average daily decrease in his account, thwn;
x = 1 day
Divide both equations
193/x = 12/1
12x = 193
x = 193/12
x = 16.08
Hence the average daily decrease in his account is 16.08

Diana bought a total of 22 items including boxes of pizza and sodas for an upcoming event. Each box of pizza cost $8 and each soda cost $1.50. If Diana spent a total of $137, which of the following is a true statement?
A. Diana bought 16 boxes of pizza.
B. Diana bought more sodas than boxes of pizza.
C. Diana bought 6 boxes of pizza.
D. Diana bought an equal number of sodas and pizzas
Answer:
B. I think
Step-by-step explanation:
1.50 times 86 equals 129 witch would mean Diana bought 86 sodas
8 is equal to 1 pizza so Dianna could have bought 1 pizza
86>1
8+129 is 137 so I think the answer is B.

B. Mia left her house 10 minutes before Erick left his house.
C. it took erick only 10 minutes to walk to the park.
D. Erick and Mia arrived at the park at the same time.
E. Erick walked the same distances as Mia during the last 10 minutes
Answer:
please continue i'm facinated on were this story goes
Step-by-step explanation:
From the graph, the correct options are given as,
B. Mia left her house 10 minutes before Erick left his house.
D. Erick and Mia arrived at the park at the same time.
E. Erick walked the same distances as Mia during the last 10 minutes.
The graph is a demonstration of curves that gives the relationship between the x and y-axis.
Here,
The graphs show their distances from home over the same 30-minute period as they walked to the park.
From the graph,
It can be concluded that,
Both reach the park at the same time, as the termination point of the curve is the same.
The graph of mia starts after 10 minutes Erick, which implies Mia left her house 10 minutes before Erick left his house. And Erick walked the same distances as Mia during the last 10 minutes as the slope of the last segment of both curves is the same.

1. A green light blinks every 4 seconds and a yellow light blinks every 5 seconds. When will both lights blink at the same time?
:
2. A red light blinks every 12 seconds and a blue light blinks every 9 seconds. When will both lights blink at the same time?
:
3. Explain how to determine when 2 lights blink together.
:
Answer:
1) both lights will blink at the same time every 20 seconds
2)Both lights will blink at the same time every 36 seconds
3) How to determine when 2 lights will blink together is that you must find the least common factor (LCM) of both numbers and when both hit the same number then that is when both lights blink at the same time.
Step-by-step explanation:
For example for number 1 we have 4 and 5 seconds when the lights blink
4: 4, 8, 12, 16, 20...
5: 5, 10, 15, 20...
we see that the LCM factor is 20 and that is when both lights will hit at the same time.

Answer:
Scalene Triangle
Step-by-step explanation:
We are told that he drew a triangle MNR. Now, the sides are given as;
MN = 2 cm
NR = 4 cm
RM = 3 cm
This means that the 3 sides are not equal. And a triangle with it's 3 sides being unequal is called a scale me triangle.

Roman was studying the life of fish, frogs, and turtles in
Doyle Park. In two hours, he counted 4 more frogs than
turtles. The number of fish he counted was twice the
number of turtles. In total, he counted 68 animals. How
many fish were there?
how many frogs were there? how many turtles were there?
Answer:
16 turtles
20 frogs
32 fish
Step-by-step explanation:
let 't' = # turtles
let '4 + t' = # frogs
let '2t' = # fish
t + 4 + t + 2t = 68
4t + 4 = 68
4t = 64
t = 16 turtles
4 + 16 = 20 frogs
2(16) = 32 fish

Calculate the annual premium for liability insurance
= bodily injury premium + property damage premium
= 310 + 245= 555
Step 2.
Add collision & comprehensive premium deductibles
555+ 148+ 102= 805
Step 3.
Calculate the total annual premium
805 x 1.45= 1167.25

identify the relationship between angles f, b, and a in the above diagram. PLEASE HELP WILL GIVE BRAINLIEST 7TH GRADE MATH
Answer:
Just remember that straight lines are always 180° (a + b = f)
Step-by-step explanation:
Assuming the triangle is equiangular and equilateral, a b and c are the same, so they are interchangeable.
f + c = 180 becuase it is a straight line. you can switch out c with a because they are the same. So:
f+a=180
(switch out with b)
f+b=180
GUESSING this is equiangular, a and b must add up to 120 because they are are both 60.
If a line is 180 degrees and c is 60 (same as a and b) then f will be 180-60 which is 120. 120 is the same as the sum of a and b, so you could write:
a + b = f
The relationship between angles f, b, and a could be as a + b = f.
What is linear pair?Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.
WE can see that the triangle is equiangular and equilateral, Also angles a b and c are the same, so they are interchangeable.
WE know that the base makes the straight line
f + c = 180
So: f + a = 180
Similarly
f + b = 180
Assuming this is equiangular, a and b must be add to 120, they are both 60 degrees
If we consider the line is 180 degrees and c is 60 then f will be 180-60 which is 120.
120 degree is the same as the sum of a and b, so we could write:
a + b = f
Hence, the relationship between angles f, b, and a could be as a + b = f.
