Answer:
written out in the explanation.
Step-by-step explanation:
Area of a circle = [tex]\pi r^{2}[/tex]
Circumference of a circle = [tex]2\pi r[/tex]
The radius is the center point of a circle to the edge of a circle. The diameter is a line from one edge of a circle to the opposite edge.
So, the radius is simply half of the diameter.
For circle A, the radius is 12. Therefore, the diameter is 24.
The circumference is 2·[tex]\pi[/tex]·12 ≈ 75.39822 inches. rounded, the circumference is 75.4 inches.
The area is [tex]\pi 12^{2}[/tex] ≈ 452.38934. rounded, the area is 452.39.
For B,
you have already solved the diameter and radius correctly, good job :). The steps for finding the circumference are the same as for circle A.
the circumference is 2·[tex]\pi[/tex]·6 ≈ 37.69911. rounded, the circumference is 37.7 inches.
the area is [tex]\pi 6^{2}[/tex] ≈ 113.09734. rounded, the area is 113.1.
For C,
the circumference is 12. We can use the circumference equation to solve for the radius.
12 = [tex]2\pi r^{2}[/tex]
divide both by 2[tex]\pi[/tex]
7.63943726841 = [tex]r^{2}[/tex]
square root of 7.63943726841 = 2.76395319577
radius = 2.76395 inches. rounded, the radius is 2.8 inches.
so, radius ·2 = 5.52790639154.
meaning diameter = 5.52791. rounded, the diameter is 5.5 inches.
the area is [tex]\pi 2.76395^{2}[/tex] ≈23.99994. rounded, the area is 24.
Marco picked 8 1/2
pounds of apples at an orchard last weekend. He used
1/4
of the apples to make a pie for a party. Then, he used 3 1/8
pounds of apples to make applesauce. How many pounds of apples does Marco have left?
Answer:
3 1/4 pounds
Step-by-step explanation:
Marco starts with 8 1/2 pounds, to make things easier rewrite it as 8.5.
He uses 1/4 (or .25) of the apples. 8.5 * .25 = 2.125. Subtract this 2.125 from the 8.5 since it's what's being used. 8.5 - 2.125 = 6.375
Then he uses 3 1/8 (or 3.125) pounds. Subtract 3.125 from the 6.375 we got previously to get 3.25.
Marco has 3.25 pounds left which can be rewritten as 3 1/4 pounds.

Answer:
327.5 feet²
Step-by-step explanation:
Let's divide the figure into multiple shapes (Refer to image). To determine the area of the figure, we need to find the area of the divided shapes, then sum it up to obtain the area of the figure.
Determining the area of the triangle:
Given dimensions:
Height = 11 feetDetermining the base of the triangle:
[tex]22 + b + 5 = 7 + 8 + 17[/tex]
[tex]27 + b = 32[/tex]
[tex]b = 32 - 27[/tex]
[tex]b = 5 \ \text{ft}[/tex]
Substituting the base and the height:
[tex]\text{Area of triangle} = \frac{1}{2} \times \text{Base} \times \text{Height}[/tex]
[tex]\text{Area of triangle} = \frac{1}{2} \times 5\times11[/tex]
Simplifying the R.H.S to determine the area:
[tex]\text{Area of triangle} = 5\times5.5[/tex]
[tex]\text{Area of triangle} = 27.5 \ \text{ft}^{2}[/tex]
Determining the area of rectangle₁
Given dimensions:
Length = 17 feetBreadth = 5 feetSubstitute the length and the breadth:
[tex]\text{Area of rectangle}_{1}} = LB[/tex]
[tex]\text{Area of rectangle}_{1}} = (5)(17)[/tex]
Simplify the R.H.S to determine the area:
[tex]\text{Area of rectangle}_{1}} = 85 \ \text{feet}[/tex]
Determining the area of rectangle₂
Given dimensions:
Length = 5 + 7 feetBreadth = 8 feetSubstitute the length and the breadth:
[tex]\text{Area of rectangle}_{2} = LB[/tex]
[tex]\text{Area of rectangle}_{2} = (7 + 5)(8)[/tex]
Simplify the R.H.S to determine the area
[tex]\text{Area of rectangle}_{2} = (7 \times 8) + (5 \times 8)[/tex]
[tex]\text{Area of rectangle}_{2} = 56+ 40[/tex]
[tex]\text{Area of rectangle}_{2} = 96 \ \text{feet}^{2}[/tex]
Determining the area of rectangle₃
Given dimensions:
Length = 17 feetBreadth = 7 feetSubstitute the length and the breadth:
[tex]\text{Area of rectangle}_{2} = LB[/tex]
[tex]\text{Area of rectangle}_{2} = (17)(7)[/tex]
Simplify the R.H.S to determing the area:
[tex]\text{Area of rectangle}_{2} = 119\ \text{feet}^{2}[/tex]
Determining the area of the figure:
A (Figure) = A (Triangle) + A (Rectangle₁) + A (Rectangle₂) + A(Rectangle₃)
= 27.5 + 85 + 96 + 119
= 327.5 feet²
An exam has two papers. Anil scores 22 out of 80 on paper 1 and 75 out of 100 on paper 2. Work out his percentage score for the exam.
Answer:
53.89%
Step-by-step explanation:
total no. obtainable = 80 + 100 = 180
total scores acquired = 22 + 75 = 97
percentage = (total acquired/total possible) × 100
= (97/180) × 100
= 53.89 %

Answer:
24040.625
Hope this helped! I'm not good at explaining the steps, but this is the answer.
please please help me
Answer:
A. 36
Step-by-step explanation:
Right triangle angles in degrees always add up to 180° degrees. In addition, it must have a right angle (hence the name right triangle), which is 90 degrees.
Given the angle in degrees is 54, we can add 90 and 54 and subtract it from 180 to find the missing angle.
[tex]54+90=144[/tex]
Now, subtract from 180.
[tex]180-144=36[/tex]
Therefore, the degrees of the missing angle is 36.

Randall wants to buy a pizza. He can select from 5 different sizes, 4 types of crust, and 12 toppings for his pizza. Which of the following shows how to find all the different possible choices of 1 size, 1 crust, and 1 pizza topping Randall can buy?
Answer:
240
Step-by-step explanation:
5x4x12=240
if you multiply the amount of sizes he can get times the amount of crust sizes he can get you get the pizza it's self (20)
now including the toppings (12) this means 20x12 gets you the amount of toppings on those induviduale pizza's.

Dante is solving the system of equations below.
r+S-=-4
2r-35+=1
3r-2s+21= 3
He writes the row echelon form of the matrix. Which matrix did Dante write?
Answer:
The answer is the first matrix. Image attached.
Step-by-step explanation: Given that Dante is solving the system of equations:
In solving the above system of equations, Dante writes the row echelon form of the matrix. We are to select the correct row echelon of the matrix that he wrote.
We know that a matrix is said to be in row echelon form if the leading entry in each nonzero row is a 1 and each column containing a leading 1 has zeros everywhere else.
In the given options, these conditions are satisfied by the first option only. And also, if we write the solution from this matrix, we will have
r = -1, s = 0 and t = 3.
If we substitute these values in the given system, it will get satisfied.
Thus, the first matrix, attached herewith, is the correct matrix.
