last question i have to ask ‘calculate the area of the shaded space’ please and thank you.
Answer:
21.5 square m
Step-by-step explanation:
You find the area of the shaded space by finding the area of the square and the removing the area of the circle.
The area for the square is 10x10=100.
All you have to do is follow the formula, (3.14)r^2. However, the 10 is NOT the diameter! The radius is half of the diameter. So, it's 3.14x5x5, which is 3.14x25=78.5.
Then, you can do 100-78.5=21.5

What is the slope of the line in this graph? please help urgent
Answer:
(b) 5/7
Step-by-step explanation:
When determining slope from a graph, it is convenient to locate points on the graph where it crosses grid lines. This graph crosses the origin, and the point (7, 5). The slope is found by counting grid squares or by the slope formula ...
m = (y2 -y1)/(x2 -x1)
m = (5 -0) /(7 -0) = 5/7 . . . . . . . . . using points (0, 0) and (7, 5)
The slope of the line is 5/7.

Ο Α. 1536
O B. 43
O C. 133
O D. 47°
Answer:
<3=C. 133
Step-by-step explanation:
Well, angle 2 and angle 3 are corrisponding angles, meaning that they are on the same line, and a line is always equal to 180, and 47 degrees is a part of that line, and you need the other part of that line for angle 3, so you simply subtract 180-47=133 degrees

The distance from earth to the moon is about 3.84 times 10^6 meters. what is one fourth of this distance
If the distance from the earth to the moon is about 3.84 x 10⁶.One-fourth of this distance will be 960,000
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 basic four operators that are +, -, ×, and ÷.
It is given that, the distance from the earth to the moon is about 3.84 x 10⁶.
One-fourth of this distance is found by dividing the total distance by 4.
We'll apply division by Splitting into equal halves or groups, the division may be used to decide how to distribute a dish of cookies evenly among a group.
Suppose the one-fourth of this distance will be x,
(1/4)× 3.84 x 10⁶ =x
x=(3.84 x 10⁶)/4
x=960,000
Thus, if the distance from the earth to the moon is about 3.84 x 10⁶. One-fourth of this distance will be 960,000

Triple u then divide 3 by the result?
Answer:
[tex]beinggreat78~is~here~to~help![/tex]
The equation should look something like this.
[tex]\frac{u(3)}{3}[/tex]
Be careful with your use between cubing and multiplying; Cubing is multiplying the number by itself multiple times, while multiplying is like repeated adding, yet much easier.
In this case, if it says triple, I highly recommend multiplying by 3, which is what I did, it only looks different because it is in parentheses.

Which value of x makes the following equation true? 2(x + 7) = x + 19 OA. 5 OB. 12 O C. 19 OD -2
2(x + 7) = x + 19
Use distributive property on left side;
2x + 14 = x + 19
Subtract 14 from both sides:
2x = x + 5
Subtract 1 x from both sides:
X = 5
F(x) =3x+8 find the inverse of f(x)
Answer:
Step-by-step explanation:
Hi!
To find the inverse, first we express your function as:
y = 3x - 8
Then, we interchange x and y variables:
x = 3y - 8
From there, we isolate y:
x + 8 = 3y
x/3 + 8/3 = y
Then, the inverse, g(x) = (x+8)/3.
We can check this by getting g(f(x)):
(f(x) + 8)/3 = (3x - 8 + 8)/3 = 3x /3 = x.
This is correct by the definition of the inverse function.
You can also think about the inverse as a "reverse function", so for example, in f(x) = 3x-8, x is multiplied by 3, then 8 is subtracted from it.
If we are to go from f(x) to x, we first add 8 (to reverse the subtraction), then divide by 3 (to reverse the multiplication).
This means g(y) = (y+8)/3, the same answer.
Hope this helps!

What is the volume of the figure?
Answer:
V = 76 ft³
Step-by-step explanation:
We can find the volume of the figure by finding the sum of volume of the small rectangular prism and big rectangular prism.
V of a rectangular prism = length*hight* width
V = V (big rectangular prism) + V (small rectangular prism)
V = (8·4·2) +(3·2·2)
V = 64 + 12
V = 76 ft³
i do not know this answer, i need help
Answer:
18 kilometers
Step-by-step explanation:
if you know the perimeter, then all you have to do is add up what you have, 10+7=17 and then subtract it giving you the bits that you dont know, so 35-17=18 kilometers.
Answer:
s = 9 Km
Step-by-step explanation:
the perimeter is the sum of the 4 sides
given perimeter = 35 , then
10 + 7 + s + s = 35
17 + 2s = 35 ( subtract 17 from both sides )
2s = 18 ( divide both sides by 2 )
s = 9 Km

1. 2(8x – 1) + 2(2x + 4)
2. 16x – 2 + 4x + 8
3. (20x + 6)
Step-by-step explanation:
The perimeter of the rectangle with length 8x - 1 and width 10x + 3 is 20x + 6
The formula for calculating the perimeter of a rectangle is expressed as:
P = 2( l + w)
Given the following parameters
length l = 8x - 1
width w = 2x + 4
Substitute the expressions for the length and width into the formula;
P = 2(8x - 1 + 2x + 4)
P = 2(10x + 3)
Distribute 2 over each term in the parenthesis
P = 2(10x) + 2(3)
P = 20x + 6
Hence the perimeter of the rectangle with length 8x - 1 and width 10x + 3 is 20x + 6

Which loan has the lowest total repayment?
==========================================================
Explanation:
Refer back to this related question
https://brainly.com/question/27362373
In that link I detail how to find that
Loan A has a monthly payment of $348.50Loan B has a monthly payment of $518.02Loan A has a duration of 5 years, aka 5*12 = 60 months. Over those 60 months, you'll pay back a total of 60*348.50 = 20,910 dollars for loan A.
Loan B has a shorter duration of 3 years = 3*12 = 36 months. Therefore, you'll pay back 36*518.02 = 18,648.72 dollars in total for loan B.
---------------
Summary total repayment
Loan A = 20,910 dollarsLoan B = 18,648.72 dollarsWe have loan B as the winner in terms of the lowest total repayment. The longer a loan is, the higher chances are that you'll pay back more in interest (thereby making the total repayment larger).
Answer :
Loan BExplanation :
Loan A's monthly payment → $348.50Loan B's monthly payment → $518.02Cost of Loan A repayment
Duration = 5 years = 5 x 12 = 60 monthsCost = 60 x 348.50 = $20,910Cost of Loan B repayment
Loan B has a shorter duration of 3 years = 3*12 = 36 months. Therefore, you'll pay back 36*518.02 = 18,648.72 dollars in total for loan B.
Duration = 3 years = 3 x 12 = 36 monthsCost = 36 x 518.02 = $18,648.72Clearly, Loan B has the lowest total repayment.
