Answer:
64 + 4.5π or 78.13 inches
Step-by-step explanation:
Dear friend,
I hope you are well. The rest of this letter will explain your math problem.
As you can see from the diagram below, there are 3 individual shapes that make up the figure. Let us find the area of each shape individually.
The formula to find the area of a circle is π[tex]r^{2}[/tex]. However, we are finding a semicircle so we must solve for half of a circle. The formula becomes [tex]\frac{1}{2} \\[/tex]π[tex]r^{2}[/tex]. The [tex]r[/tex] in the formula is the radius. It is given the diameter (which is double the radius) is six. Therefore, the radius is 3 in. If plug in the values we get [tex]\frac{1}{2}(3^{2})[/tex]π which is 4.5π I am not sure if you want the answer in terms of π or just the estimated value. The estimated value (using 3.14 instead of π) would be 14.13.
Now we shall find the area of the rectangle. This is a 6x10 inch rectangle. The answer is 60. You probably know how to solve multiplication. 6 can be seen as 6.0. Multiplying by 10 moves the decimal point one number to the right so it becomes 60.0: 60.
The length of the base of the triangle can be found even though the diagram does not directly give us the base length. the length of the base of the rectangle and triangle combined is 14 inches. We know that the rectangle has a base length of 10 because it is given. Therefore we must find the remaining length which is 4 because 14-10=4. The formula for finding the area of a triangle is [tex]\frac{(base)(height)}{2}[/tex] we know that the base is 4 and the height is 6 so we plug in the numbers and simplify to get 12.
We must add each of the areas to find the area of the whole figure. The Semi-circle is 4.5π(14.13) and the rectangle is 60 and the triangle is 4. The answer is 64 + 4.5π or 78.13

Of the 120 math tests, 47 were Bs. What percent of the math tests were Bs? Round to the nearest whole percent.
Answers
Answer:
39.17%
Step-by-step explanation:
Answer:
39%
Step-by-step explanation:
Percent is ALWAYS out of 100, and the unknown is percent so our first part of the equation will be %/100. Now our second part of equation: is/of
Of represets whole the total, and we have our key word “Of the 120 math tests”. We have our total: 120; 47 is our part so second part of equation: 47/120.
Our equation so far: %/100 = 47/120 now we need to multiply the numbers that we have diagonally: 100% x 47; 47/100 we’re multiplying so we’ll move two 0s to the right. Answer: 4700
Now, we’ll divide 4700 by 120. 4700/120. Answer: 39.1666666667. Round to nearest whole means round to nearest ones.
Thus, the answer is 39.
Hope this is helpful!
Carrie and Diana ate lunch at a restaurant.
They ordered 1 pizza that cost $13.02.
Diana ordered chicken wings for $12.99 and a drink for $3.25.
Carrie ordered a salad for $6.25 and a drink for $3.25.
They left a $10.00 tip.
Diana paid for her food, plus half the cost of the pizza and half the tip. What was the total amount Diana paid?
A.$33.78
B.$27.75
C.$27.04
D.$20.77
Answers
Answer:
B) 27.75
Step-by-step explanation:
12.99+3.25=16.24
Half the tip is 5
5+16.24=21.24
Half the pizza is 6.51
21.24+6.51=27.75
The total amount paid by Diana will be equal to $27.75. Hence, option B is correct.
What is arithmetic Operations?The four fundamental operations of arithmetic are addition, subtraction, multiplication, and division of two or even more items.
Included in them is the study of integers, especially the order of operations, which is important for all other areas of mathematics, notably algebra, data management, and geometry.
As per the data given in the question,
Price of pizza = $13.02
Half price of pizza paid by Diana = 13.02/2 = $6.51
Price of chicken wings ordered by Diana = $12.99 and,
Price of drink that is also ordered by Diana = $3.25
Then, tip price is $10 which is paid half by Diana = $5
Then, the total expenditure by Diana will be,
= 6.51 + 12.99 + 3.25 + 5
= $27.75

Explain relationship between the factors of a quadratic expression, the roots of the related quadratic equation, and the x-intercepts if the graph of the related function
Answers
Step-by-step explanation:
So, let's use x2 - 3x - 28 as an example.
It's factors are (x - 7)(x + 4).
The roots are the x-values that make our expression equal 0. In order for x2 - 3x - 28 to equal 0, either of our factors need to equal 0, since 0 times anything is 0.
x2 - 3x - 28 = 0
(x - 7)(x + 4) = 0
x - 7 = 0
x = 7
(7 - 7)(7 + 4) = 0(11) = 0
x + 4 = 0
x = -4
(-4 - 7)(-4 + 4) = -11(0) = 0
That gives us two points on our graph, (7,0) and (-4,0). Where are those? On the x-axis! Thus, there are our x-intercepts.
By the way, for the future, along the x-axis, y = 0, so if you are asked for the x-intercepts (or roots), set y = 0 and solve for x.
Along the y-axis, x = 0, so if you are asked for the y-intercepts, set x = 0 and solve for y.
y = 02 - 3(0) - 28
y = -28
So, the y-intercept(s) of our same equation is y = -28, or (0,-28).
Boom.
Answer:
The x-intercepts are happen are when y = 0. If you tried to substitute y = 0 into a quadratic in the standard form you can not use traditional methods for solving for x.
Y=0 when looking for an x-intercept. Doing the factored form you are finding the x-intercepts. You always want the equation to equal 0 then factor out the equation till you get the numbers for the x-intercept.

The slope will be the same for a straight line no matter which two points you pick as you know. All you need to do is to calculate the difference in the y coordinates of the 2 points and divide that by the difference of the x coordinates of the points(rise over run). That will give you the slope.

Drag each expression to show whether it is equivalent to 4 × 5 or to 2 × 4 × 5.
Answers
Answer:
1st one: 4x5x2: in the 2nd box
2nd one: (4x2)+(4x3) : in the 1st box
3rd one: 2x(4x5): in the 2nd box
Last one: 4x(1+4): in the 1st box
Step-by-step explanation:
For the first one: 4x5x2, you can multiply any 2 numbers together example- you can multiply 4x5, 5x2, 4x2 then multiply the third digit I did 4x5=(20) x2= 40.. 5x2 =10 x4=40.. see they'll all end up to 40.
For the second one: (4x2)=8 (4x3)=12 add 8 and 12 it'll equal 20
For the third one: 2x(4x5) start by multiplying 4 and 5 which is 20, then multiply 20 by 2 =40
For the fourth one: 4x(1+4) 1+4=5, multiply 5 by 4 and get 20
The first box equals 40, the second box equals 20
And always remember to answer the problem in the parenthesis first, then continue with the rest of the problem. Hope this helps!! And I hope I didn't confuse any of you.. Let me know if you have any questions or if I made a mistake somewhere but besides all that have a great day! :)
4 × 5 equivalent to (4×2) + (4×3) and 4(1+4), 2 × 4 × 5 is equivalent to 4×5×2 and 2(4×5)
What is an arithmetic operation?It is defined as the operation in which we do the addition of numbers, subtraction, multiplication, and division. It has a basic four operators that is +, -, ×, and ÷.
= 4×5×2 = 40
=(4×2) + (4×3) = 8+12 = 20
= 2(4×5) = 40
= 4(1+4) = 4(5) = 20
We have:
4 × 5 = 20 2 × 4 × 5 = 40
(4×2) + (4×3) 4×5×2
4(1+4) 2(4×5)
Thus, 4 × 5 equivalent to (4×2) + (4×3) and 4(1+4), 2 × 4 × 5 is equivalent to 4×5×2 and 2(4×5)
