So, the formula to find the are of a triangle is A=1/2bh
So the height of the triangle is 3 m and the base is 4 m.
So, you have to do A= 1/2×3×4, which equals to 6 m²
So, the area of the triangle is 6 m²
For the rectangle however, the formula to find the area is A=bh
So the base of the rectangle is 6 and the height is 3
So, you do A=6×3, which is 18
So, the area of the rectangle is 18 m²
Now, for the semi-circle, the formula to find the area is A= 1/2×pi×r²
So the radius of the semi-circle is 3 because 6÷2=3
So, what you do is A=1/2×3.14×3²,which equals 14.13
Finally, you have to add all the answers you just got, which would be 6+18+14.13, which would equal 38.13
So, your final answer would be 38.13 m²

By simplifying the given linear equation and combining like terms, we find that the single solution is x = 0. Verification confirms that this solution is valid as it satisfies the original equation.
Explanation:
The equation presented by the student is a linear equation with the variables on both sides. To solve this equation, we will combine like terms and isolate the variable x on one side of the equation.
First, let's simplify the equation by combining like terms:
-4x - 7 + 10x = -7 + 6x
Combine x terms on the left side and numerical terms on the right:
6x = 0
Finally, divide by the coefficient of x to solve for x:
x = 0
This value of x is the single solution to the equation. It's important to note that there are no other solutions in this case, as it's a simple linear equation and not a quadratic or higher-order polynomial equation.
Verification
To verify that x = 0 is indeed a solution, we can substitute it back into the original equation:
-4(0) - 7 + 10(0) = -7 + 6(0)
All terms involving x drop out, confirming that -7 = -7 is an identity, making x = 0 a valid solution.

Rewrite the exponential function y = 12 (0.56)^(t/4).
Round your answer to two decimal places.
Answers
y = 12 (0.56)^(t/4)
y=12(0.56^(1/4))^t
but
0.56^(1/4)=0.8651
thus plugging the value in y we get:
y=12(0.8651)^t
in two decimal places we get:
y=12(0.87)^t
The exponential function will be written as:
y = 12 (0.56) ^ (t/4)
y=12 (0.56^ (1/4)) ^t
but
0.56^ (1/4) = 0.8651
thus plugging the value in y we get:
y=12 (0.8651) ^t
in two decimal places we get:
y=12 (0.87) ^t

ehat is the value of y=3x2-18x+15
Answers
The value of the equation y = 3x^2 - 18x + 15 can be found by substituting different values of x and calculating the corresponding value of y.
Explanation:The value of the equation y = 3x^2 - 18x + 15 can be found by substituting different values of x and calculating the corresponding value of y. For example, if we substitute x = 1, we get y = 3(1)^2 - 18(1) + 15 = 0. So, when x = 1, y is 0.
To find more values, we can create a table of values by substituting different x values into the equation. The resulting values of y can be plotted on a graph to see the pattern and shape of the equation.
Table of Values:
x = 0, y = 15x = 1, y = 0x = 2, y = 9x = 3, y = 18This equation represents a quadratic function in the form of y = ax^2 + bx + c, where a = 3, b = -18, and c = 15.

If the probability of winning a carnival game was 2/5 and Max played it five times, write an expression that would calculate the probability he won the first three games and lost the last two
Answers
Prob(losing carnival game) = 3/5
Prob (Max wins first 3 games, but loses last 2 games)
= Prob(Max wins game 1) * Prob(Max wins game 2) * Prob(Max wins game 3) * Prob(Max loses game 4) * Prob(Max loses game 5)
The probability of Max winning the first three games while losing the rest two is 0.023.
What is Probability?The probability helps us to know the chances of an event occurring.
[tex]\rm Probability=\dfrac{Desired\ Outcomes}{Total\ Number\ of\ outcomes\ possible}[/tex]
As it is given that the probability of winning the game is 2/5. Since the sum of all the probability of an event is 1, therefore, the probability of losing the game can be written as,
Sum of all probability = Probability of winning + Probability of losing
[tex]1 = \dfrac25+\text{(Probability of losing)}\\\\\text{(Probability of losing)}=\dfrac35[/tex]
Thus, the probability of losing the game is 3/5.
As we need to calculate the probability of Max winning the first three games while he losing the rest two. Therefore,
[tex]P = \dfrac25 \times \dfrac25 \times \dfrac25 \times \dfrac35 \times \dfrac35 = \dfrac{72}{3125} = 0.023[/tex]
Hence, the probability of Max winning the first three games while losing the rest two is 0.023.

circumference=2*3.14*3
=18.84cm2=rounded to the nearest tenth=18.8cm2
The closest answer is 18.9cm2
Hope this helps you.
Answer:
The area of the circle is equal 28.3 cm² to the nearest tenth.
Step-by-step explanation:
To find the area of the circle that has a radius of 3, we will simply use the formula;
Area of a cirle = π r²
where π is a constand and r is the radius.
From the question given π = 3.14 and r=3
We can now proceed to insert the value into the formula;
Area of a cirle = π r²
=3.14×3²
=3.14×9
=28.26
≈28.3 cm²
Therefore, the area of the circle is equal 28.3 cm² to the nearest tenth.

108/72 = 1.5
132/80= 1.65
I would say A and B are similar, not C
Step-by-step explanation: We are given three rectangular figures A, B and C.
We need to determine which polygons are similar and which are not.
Note: The sides of similar figures are in proportion.
Let us check first A and B figures.
150/108 = 50/36
100/72 = 50/ 36.
We can see 150/108 = 100/72 = 50/ 36.
Sides are in proportion of Polygons A and B.
So, the Polygons A and B are Similar.Let us check first A and C figures.
150/132 = 25/22
100/80 = 5/4.
We can see 150/132 ≠ 100/80.
Sides are not in proportion of Polygons A and C.
So, the Polygons A and C are Not Similar.Let us check first B and C figures.
108/132 = 9/11.
72/80 = 9/10.
We can see 108/132 ≠ 72/80.
Sides are not in proportion of Polygons B and C.
So, the Polygons B and C are Not Similar.A repairman leans the top of an 8 ft ladder against the top of a stone wall the base of the ladder is 5.5 ft from the wall about how tall is the wall round to the nearest tenth of a foot

B. 5 1/12
C. 4 1/2
D. 1 5/12
Answers
Brand had 2 5/12 cups of chili left over from the second batch (option A). This was determined by solving the equation 1 1/3 + x = 3 3/4 using improper fractions and subtraction.
To find out how many cups of chili were left over from the second batch, we need to solve for x in the equation 1 1/3 + x = 3 3/4. Firstly, convert the mixed numbers to improper fractions: 1 1/3 becomes 4/3 and 3 3/4 becomes 15/4.
Now the equation looks like this: 4/3 + x = 15/4. To find x, subtract 4/3 from both sides of the equation.
15/4 - 4/3 = (15*3 - 4*4)/(4*3) = 45/12 - 16/12 = 29/12.
Now convert the improper fraction back to a mixed number. 29/12 is 2 and 5/12. So Brand had 2 5/12 cups of chili left over from the second batch (option A).

Solve: q to the second power =36
Answers
The equation q^2=36 has two solutions because both a positive and a negative number squared can result in a positive number. The solutions are q=6 and q=-6, illustrating the concept of integer powers and square roots.
Explanation:To solve the equation q squared equals 36 (q2 = 36), we look for the number that, when multiplied by itself, gives the product of 36. In mathematics, finding a value that satisfies this condition involves taking the square root of both sides of the equation. Thus, we have two potential solutions since both positive and negative values can be squared to yield a positive result.
The square root of 36 is 6, so our equation gives us two possible solutions: q = 6 or q = -6. This demonstrates the concept of integer powers, where for instance, raising 4 to the power of 3 (43) means multiplying 4 by itself three times. When dealing with the square root, we are essentially doing the opposite: we are asking what number multiplied by itself gives us the original number under the square power.
