Find the diameter of each circle.
Answer:
Diameter Length: ( About ) 5.4 km; Option B
Step-by-step explanation:
~ Let us apply the Area of the Circle formula πr^2, where r ⇒ radius of the circle ~
1. We are given that the area of the circle is 22.9 km^2, so let us substitute that value into the area of the circle formula, solving for r ( radius ) ⇒ 22.9 = π * r^2 ⇒ r^2 = 22.9/π ⇒ r^2 = 7.28929639361.... ⇒
radius = ( About ) 2.7
2. The diameter would thus be 2 times that of the radius by definition, and thus is: 2.7 * 2 ⇒ ( About ) 5.4 km
Diameter Length: ( About ) 5.4 km
You are stacking wooden blocks (cubes) whose sides are all 1 1/4 inches how many blocks do you need to stack or build a block tower that is 7 1/2 inches tall
Answer: You need to stack 6 blocks to build the block tower.
Step-by-step explanation:
Hi, to answer this question we simply have to divide the tower's height (7 1/2) by the side length of the cubes (1 1/4).
Mathematically speaking:
7 1/2 ÷1 1/4 = (7x2+1) /2 ÷ (1x4+1)/4 = 15/2 ÷ 5/4 = (15x4) / (2x5) = 60/10 =6 cubes
You need to stack 6 blocks to build the block tower.

What is an equation of the line that passes through the points (6,0) and (−1,−7)
Answer: y= 1x - 6
Step-by-step explanation:
(6,0) (-1,-7)
0-(-7)= 7
6-(-1)= 7
7/7= 1 so the slope is 1 and we just need to find the y-intercept and we will do that by using the formula y= mx +b
-7= 1(-1) + b
-7= -1 + b
+1 + 1
b= -6 so the y-intercept is -6.
Answer:
y= 1x - 6

Dylan invested $7,200 in an account paying an interest rate of 2.3% compounded quarterly. Assuming no deposits or withdrawals are made, how much money, to the nearest dollar, would be in the account after 12 years?
Answer:
$9,481.01
Step-by-step explanation:
The formula for compound amounts is
A = P(1 + r/n)^(nt), where n is the number of compounding periods per year, t is the number of years, P is the initial amount invested and r is the annual interest rate as a decimal fraction.
Here,
A = ($7,200)(1 + 0.023/4)^(12*4)
Evaluating this we get:
A = ($7,200)(1.00575)^48, or
A = ($7,200)(`1.3168) = $9,481.01
Answer:
9,481.01

What is important to keep in mind when selecting a sample?
a. The sample should be chosen based on specific criteria, such as the youngest students in the class.
b. The sample should be chosen at random so that it is fair.
c. The sample should consist of every person in the population being studied.
d. The sample size should always be exactly one person or piece of data.
Answer: b. The sample should be chosen at random so that it is fair.
Step-by-step explanation:
One of the most important things when selecting a sample is that the sample must be totally random if the sample is not random (for example, selecting only the youngest people in a group or things like that) there is a high probability that the sample will be biassed towards something, so the study may not be really accurate for all the population.
The correct option is b. The sample should be chosen at random so that it is fair.
The length and breadth of a rectangular shaped plot is 1215 m and 527 m respectively. Find its perimeter.
Answer:
3484m
Step-by-step explanation:
Perimeter of a rectangle= 2(L+B) where L= Length and B= Breadth
Length of the plot= 1215m
Breadth= 527m
∴ Perimeter of the plot= 2(1215m+527m)
= 2(1742m)
= 3484m

5x + 8 - 3x = -10
x = -9
x = -1
оооо
X = 1
O x= 9
Answer:
x = -9
Step-by-step explanation:
5x + 8 - 3x = -10
Combine like terms
2x +8 = -10
Subtract 8 from each side
2x+8-8 = -10-8
2x = -18
Divide each side by 2
2x/2 = -18/2
x = -9
Grace has $81 in her bank account and deposits $68 per month into her account. Jasmine has $53 and deposits $75 per month into her account. Enter the number of months it will take for both Grace and Jasmine to have the same amount of money in their accounts.
Answer:
4 months
Step-by-step explanation:
Let the number of months that they deposit into their accounts be m.
Grace has $81 in her bank account and deposits $68 per month into her account. This means that after m months, she will have:
81 + 68m
Jasmine has $53 and deposits $75 per month into her account. This means that after m months, she will have:
53 + 75m
To find the number of months it will take for them to have the same amount, we equate the amount that they each have:
81 + 68m = 53 + 75m
Collect like terms and simplify:
81 - 53 = 75m - 68m
28 = 7m
=> m = 28 / 7 = 4
It will take 4 months for them to have the same amount.

A regular hexagon and a regular octagon are joined as shown on the diagram
Work out the size of angle x
Answer:
x = 105°
Step-by-step explanation:
The shape above is a regular hexagon and a regular octagon the both of them have the same interior angle through out. For a polygon to be regular all it interior angle are the same .
sum of interior angles of a polygon = (n - 2)180°
where
n = number of sides
Therefore,
sum of interior angle of a hexagon = (6 - 2)180
sum of interior angle of a hexagon = (4)180
sum of interior angle of a hexagon = 720
each angle of a regular hexagon = 720/6 = 120°
sum of interior angles of an octagon = (8- 2)180
sum of interior angles of an octagon = (6)180
sum of interior angles of an octagon = 1080
each angle of a regular octagon = 1080/8 = 135°
All the angle around a point add up to 360°. So if we take the interior angle from 360° we will get angle x
360 - (135° + 120°)
360 - 255
x = 105°
Answer:
105

Dreg earns $6.80 per hour. On Saturday he worked from 9:00 A.M.
to 3:30 P.M. How much did he earn?
Answer:
$44.20
Step-by-step explanation:
First, calculate how many hours he worked. From 9:00am-3:30pm he worked 6.5 hours. We're going to multiply the hourly rate, $6.80 by how many hours he worked. Since he also worked an extra half hour and not a full hour we're going to divide $6.80 by 2. Then add both of the calculations up to get the asnwer.
6.8(6)=40.8
6.80/2=3.4
40.8+3.4=44.2
He earned $44.20.
Quadrilateral A^ prime B^ prime C^ prime D^ prime is the image of quadrilateral ABCD under a rotation about point Q
A: -90
B: -60
C: 60
D: 90
When a shape is rotated, it must be rotated through a point.
The rotation from [tex]ABCD[/tex] to [tex]A'B'C'D'[/tex] is (d) [tex]90^o[/tex]
To determine the angle of rotation from [tex]ABCD[/tex] to [tex]A'B'C'D'[/tex], we use the following steps
Connect a point and the image of the point to the center of rotation.Measure the angle at the point of rotationDraw an arrow from [tex]ABCD[/tex] to [tex]A'B'C'D'[/tex] to determine the direction of rotation.See attachment for illustration.
From the attached image;
We draw A and A' to point QThen we measure the angle at Q; this gives [tex]90^o[/tex].The arrow from [tex]ABCD[/tex] to [tex]A'B'C'D'[/tex] indicates a clockwise directionHence, the angle of rotation is D: 90
