Based on the description of the diagram, we get simplified expression is 6 + 3c.
Describe Algebraic Expression?An algebraic expression is a mathematical phrase that consists of variables, constants, and arithmetic operations (such as addition, subtraction, multiplication, and division), as well as exponentiation and roots. These expressions are used to represent mathematical relationships and formulas in a concise and standardized way.
Based on the description of the diagram, we can simplify the expression as follows:
There are 4 squares labeled 1, so their total value is 4.
There are 2 rectangles labeled c, so their total value is 2c.
There are 2 squares labeled 1, so their total value is 2.
There is 1 rectangle labeled c, so its value is c.
Therefore, the expression represented by the diagram simplifies to:
4 + 2c + 2 + c
6 + 3c
So the simplified expression is:
6 + 3c.

Billy wants to find out which cafeteria food is the favorite in his school for students. He surveys 100 students. 29 students select sub sandwiches, 35 select steak and gravy, and 36 select fried chicken. if you select one of these students. What is the probability it will be a student who prefers chicken
Answer choices
A. 7/20
B. 9/25
C. 40%
D.29/100
Answer:
36% or 9/25
Step-by-step explanation:
35+36+29=100 so 100-35-29=64 and 36 are left so you divide 9/25 and you get 0.36 and you put it into a percentage and the answer is 36% or 9/25.
The probability it will be a student who prefers chicken is, 36/100.
What is probability?Probability is a mathematical term, which can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event. The possibility that an event will occur is measured by probability.
Probability of Event = Favorable Outcomes/Total Outcomes = X/n
Given that,
He surveys 100 students,
29 students select sub sandwiches,
35 select steak and gravy,
and 36 select fried chicken
The probability of selecting a student who prefers fried chicken can be found by dividing the number of students who prefer chicken by the total number of students surveyed:
36/100 = 36%.
This can also be expressed as a decimal or a percentage:
0.36 or 36%.

The "unit rate" is always the y-value for x=1 when the relationship is proportional (as it is here).
That point is not specifically shown on the graph. It would be (1, 1/6).
Above are two different models of the same triangle. If the area of the model on the left is 24 sq cm, what is the area of the model on the right?
The area of the model on the right = area of model on the left × 3² = 216 sq. cm.
What is a Model?A model represents a real object on a drawing paper.
Given that the model is triangular in shape, the model on the right is 3 times the model on the left.
Therefore, area of model on the left = area of model on the left × 3².
Area of model on the left = 24 × 9
Area of model on the left = 216 sq. cm.

Find the simple interest and amount when principal = Rs. 6000, rate = 6% per annum and time = 4 years
Given:
Principal = Rs. 6000
Rate of simple interest = 6% per annum.
Time = 4 years
To find:
The simple interest and amount.
Solution:
Formula for simple interest:
[tex]I=\dfrac{P\times r\times t}{100}[/tex]
Where, P is principal, r is the rate of interest and t is the number of years.
Putting P=6000, r=6 and t=4, we get
[tex]I=\dfrac{6000\times 6\times 4}{100}[/tex]
[tex]I=60\times 6\times 4[/tex]
[tex]I=1440[/tex]
Now,
[tex]Amount=Principal+Interest[/tex]
[tex]Amount=6000+1440[/tex]
[tex]Amount=7440[/tex]
Therefore, the simple interest is Rs. 7440 and the amount is Rs 7440.

The size is 22.6 degrees, but how did they get it?
Answer:
Step-by-step explanation:
a). Since, BC is perpendicular to the plane FEDC, measure of angle BCD = 90°
By applying Pythagoras theorem in ΔBCD,
BD² = BC² + CD²
BD² = (10)² + (24)²
BD = √676
BD = 26 cm
B). Surface area of the wedge = Sum of all the surfaces of the wedge
Area of BCD = Area of AEF = [tex]\frac{1}{2}(\text{Base})(\text{Height})[/tex]
= [tex]\frac{1}{2}(10)(24)[/tex]
= 120 cm²
Area of CDEF = Length × Width
= ED × CD
= 26 × 24
= 624 cm²
Area of BCFA = 10 × 26 = 260 cm²
Area of ABDE = ED × BD
= 26 × 26
= 676 cm²
Total surface area of the wedge = 2(120) + 624 + 260 + 676
= 1800 cm²
C). Volume of the triangular prism = Area of the triangular base × Height
= (Area of BCD) × DE
= 120 × 26
= 3120 cm³
d). By applying sine rule in the right triangle BCD,
sin(∠BDC) = [tex]\frac{\text{Opposite side}}{\text{Hypotenuse}}[/tex]
= [tex]\frac{BC}{BD}[/tex]
m(∠BDC) = [tex]\text{sin}^{-1}(\frac{10}{26})[/tex]
= 22.6°

Gavin drank 3/4 of a liter of orange juice from the container, which was 3/8 of the orange juice that was originally in the container. How much orange juice was originally in the container?
Answer:
Originally there were 2 liters.
Step-by-step explanation:
--
3/8 of the orange juice = 3/4 liter
1/8 of the orange juice = 3/4 ÷ 3
1/8 of the orange juice = 3/4 x 1/3
1/8 of the orange juice = 1/4 liter
Find 8/8, which is one whole.
1/8 of the orange juice = 1/4 liter
8/8 of the orange juice = 1/4 x 8
8/8 of the orange juice = 2 liters
There were originally 2 liters of orange juice in the container

It will take ---------
seconds for the ball to hit the ground??
Answer:
Step-by-step explanation:
It will hit the ground when height is equal to zero.
-16t^2+64t=0
-16t(t-4)=0
t=4 seconds
