Answer:
$29
Step-by-step explanation:
8x9=71
100-71=29
Answer:
28
Step-by-step explanation:
It's 28 because 9 x 8 = 72
So 100 - 72 = 28
The radius of a circle is increased by 3 in., which increases the area by 100 in. Find the radius of the original circle. Round to the nearest hundredth.
Answer:
3.81 inches
Step-by-step explanation:
πr² + 100 = π(r+3)²
divide by π and simplify:
r² + (100/π) = r² + 6r + 9
100/π = r² + 6r + 9
31.8309886184 - 9 = r² +6r
r² = 6r - 22.8309886184
0 = 6r - 22.8309886184
22.8309886184 = 6r
divide by 6:
3.80516476973 ≈ 3.81 inches

The square of a number x is 16 more than six times the number
Form an equation in x and solve it.
Answer:
x= 8
Step-by-step explanation:
x^2 = 6x+16
TAKE RHS OVER TO LHS TO EQUATE IT TO 0
x^2 - 6x - 16 = 0
FACTORISE
(x-8)(x+2) =0
Therefore
x-8= 0 or x+2= 0
x= 8 or x= - 2
Sub and see which works
8^2 = 6(8) + 16
64= 64
-2^2 = 6(-2) + 16
-4= 4
So the answer must be
x= 8

Molly and Tess like to shop at the mall. Molly has $280 in her bank account and spends $40 every trip
The number of trips that Molly and Tess did was 7.
What is the arithmetic operator?Arithmetic operators are four basic mathematical operations in which summation, subtraction, division, and multiplication involve.,
As per the given,
Molly has $280 in her bank account and spends $40 on every trip.
Number of trips = Account balance / spent in every trip
⇒ $280/$40 = 7
Hence "The number of trips that Molly and Tess did was 7".

During a walk-a-thon, Noah's time in hours, t, and distance in miles, d, are related by the equation ⅓ d = t. A graph of the equation includes the point (12, 4). Identify the independent variable. What does the point (12, 4) represent in this situation? What point would represent the time it took to walk 7 ½ miles?
Answer:
The Indapendent virable is: t
Noah took 4 hours to walk 12 miles
(7 1/2, 2 1/2)
Step-by-step explanation:
I hope this is right!
The point that represents the time it took to walk 7 ½ miles is (2.5, 7.5).
What is coordinate?Coordinate, is represented as the values on the x-axis and y-axis of the graph. while the coordinate x is called abscissa and the coordinate of the y is called ordinate.
Here,
The independent variable in this situation is time (t).
Point (12, 4) represents that Noah walked for 4 miles in 12 hours.
To find the point that represents the time it took to walk 7 ½ miles, we need to solve for t in the equation ⅓ d = t.
Substituting d = 7.5, we get:
⅓ (7.5) = t
Simplifying, we get:
t = 2.5
Therefore, the point that represents the time it took to walk 7 ½ miles is (2.5, 7.5).

Jason wants to add a fence to his yard to make it the shape of a rectangle. What is the measure of angle MKJ in the portion of the yard not inside the fence?
Answer:
[tex]\angle MKJ = 34[/tex]
Step-by-step explanation:
Given
[tex]\angle LKJ = 124[/tex]
Required
Find [tex]\angle MKJ[/tex]
From the attachment:
The measure of [tex]\angle MKJ[/tex] is calculated using the following expression:
[tex]\angle MKJ + \angle LKM = \angle LKJ[/tex]
Where
[tex]\angle LKM = 90[/tex] -- right-angled.
The expression becomes
[tex]\angle MKJ + 90 = 124[/tex]
[tex]\angle MKJ = 124 - 90[/tex]
[tex]\angle MKJ = 34[/tex]

What is 3 divided by 6 Keep change flip?
Step-by-step explanation:
Multiply by the reciprocal, also sometimes referred to as "Keep, Change, Flip." Here is how it works. You rewrite the division question as a multiplication question by flipping the second fraction over. Next, keep the first number, change the division to multiplication and then flip the second fraction over.
Use the given set to determine the solution for each equation.
7t + 26 = 61 {3, 5, 7, 9}
t=_________
Answer:
5
Step-by-step explanation:
you have to subtract 26 on both sides.
so then the equation turns into 7t = 35
then you dive both sides by 7, leaving the equation as t=5
Carran is building a fence around his rectangular yard. The fence will cover the front and the 2 sides of the yard. The
front of the yard is 4 feet more than twice the length of one side of the yard. The sides of the yard are the same length. If
the perimeter of the yard is 80 feet, what are the dimensions of the fence?
9514 1404 393
Answer:
sides: 12 feetfront: 28 feetStep-by-step explanation:
Let x represent the length of one side of the yard. Then the width of the yard is 2x+4, and the perimeter is ...
P = 2(L +W) . . . . . . . . . . formula for perimeter of a rectangle
80 = 2(x + (2x+4)) . . . . . with values from the problem filled in
40 = 3x +4 . . . . . . . . divide by 2, collect terms
36 = 3x . . . . . . . . . subtract 4
12 = x . . . . . . . . . divide by 3. This is the length of the side fence.
2x +4 = 2(12) +4 = 28
The fence is 12 feet on the sides and 28 feet on the front. (Its total length is 52 feet.)
Find the diameter of each circle. Round your answer to the nearest tenth
Please help and explanation will give BRAINLIST
Answer:
7.2
Step-by-step explanation:
to find the diameter you always times it by 2
whilst to find the radius you do diameter ÷ 2
so if you times 3.6 x 2 = 7.2
also, you can't round 7.2 to the nearest tenth because it's already in that form
Answer:
Step-by-step explanation:
a radius is the length of a line segment from the center of a circle to the edge of the circle
a diameter is the length of a line segment from both edges of a circle and passing through the center of a circle
the line segment in the diagram looks like a radius (assuming the black dot represents the center of the circle)
if you left the line segment where it is and then rotate another the line segment in the diagram around so that is straight in line with the original line segment you would see that you just created a diameter
the diameter is twice as long as one radius
a diameter = 2 times a radius d = 2r d = diameter r = radius
so d = 2 x 3.6 use your own calculator to solve
