The floor of a shed has an area of 70 square feet. The floor is in the shape of a rectangle whose length is 4 feet less than twice the width. Find the length and the width of the floor of the shed.
Answer:
length: 10 ft; width: 7 ft.
Step-by-step explanation:
Factorizations of 70 are ...
70 = 1·70 = 2·35 = 5·14 = 7·10
The last pair of numbers has the relation that 2·7 -10 = 4, so the numbers 7 and 10 can be used for width and length.
The length is 10 ft; the width is 7 ft.
lola uses 44 beads to make a bracelet and 96 beads to make a necklace write an expression to show how you could calculate the total number of beads lola used to make 13 bracelets and 8 necklaces
Answer: 1,340 :)
Step-by-step explanation:
44*13= 572
96*8=768
572+768=1,340
Final answer:
The expression to calculate the total number of beads Lola used to make 13 bracelets and 8 necklaces is 13 × 44 + 8 × 96, with the total being 1340 beads.
Explanation:
To calculate the total number of beads Lola used to make 13 bracelets and 8 necklaces, we need to consider the number of beads used for one bracelet and one necklace individually. For one bracelet, Lola uses 44 beads, and for one necklace, she uses 96 beads.
For 13 bracelets: 13 (bracelets) × 44 (beads per bracelet) = 572 beadsFor 8 necklaces: 8 (necklaces) × 96 (beads per necklace) = 768 beadsNow, we add the two quantities together to get the total number of beads used:
572 beads (for bracelets) + 768 beads (for necklaces) = 1340 beads
Therefore, the expression to calculate the total number of beads used is 13 × 44 + 8 × 96.
To the nearest degree, what is the measure of each exterior angle of a regular heptagon?
Answer:
51°
Step-by-step explanation:
The sum of all exterior angles of any polygon is always 360°.
To find the measure of one of these angles, divide 360° by the number of sides of the polygon
In this case, we have 7 sides, so
m = 360°/7 = 51.42°, or 51° rounded to the nearest degree

A store is having a sale on trail mix and jelly beans. For 2 pounds of trail mix and 3 pounds of jelly beans, the total cost is 13. For 4 pounds of trail mix and 8 pounds of jelly beans, the total cost is $33. Find the cost for each pound of trail mix and each pound of jelly beans.
Answer:
trail mix: $1.25jelly beans: $3.50 per poundStep-by-step explanation:
The difference between double the first purchase and the second purchase is $7 and 2 pounds of jelly beans. Hence a pound of jelly beans is $3.50.
(4t +8j) -2(2t +3j) = (33) -2(13) . . . . . let t and j represent pounds of trail mix and jelly beans, respectively
2j = 7 . . . . . . . . . . simplify
j = 7/2 = 3.50
Using that value in the first purchase, we get ...
2t +3(3.50) = 13
2t = 13 -10.50
t = 2.50/2 = 1.25
A pound of trail mix is $1.25.
A circle centered at (–1, 2) has a diameter of 10 units. Amit wants to determine whether (2, –2) is also on the circle. His work is shown below. The radius is 5 units. Find the distance from the center to (2, –2). The point (2, –2) doesn’t lie on the circle because the calculated distance should be the same as the radius. Is Amit’s work correct? No, he should have used the origin as the center of the circle. No, the radius is 10 units, not 5 units. No, he did not calculate the distance correctly. Yes, the distance from the center to (2, –2) is not the same as the radius.
The distance from the center of the circle at (-1,2) to the point (2,-2) is 5 units and he did not calculate the distance correctly
What is the distance of a line between 2 points?The distance of a line between 2 points is always positive and given by the formula
Let the first point be A ( x₁ , y₁ ) and the second point be B ( x₂ , y₂ )
The distance between A and B is D , and the distance D is
Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²
Given data ,
Let the first point be P = P ( -1 , 2 )
Let the second point be Q = Q ( 2 , -2 )
To find the distance from the center of the circle at (-1,2) to the point (2,-2), we can use the distance formula:
Distance D = √ ( x₂ - x₁ )² + ( y₂ - y₁ )²
Distance D = √[(2 - (-1))² + (-2 - 2)²]
Distance D = √[3² + (-4)²]
D = √[9 + 16]
D = √25 = 5 units
Therefore, the point (2,-2) does lie on the circle.
However, Amit's work does not account for the fact that the center of the circle is not at the origin, but rather at (-1,2). This means that the distance from (-1,2) to (2,-2) must be used to determine if the point is on the circle, not the radius of the circle.
No, he should have used the center of the circle at (-1,2) to calculate the distance.

Eva buys online tickets to a play for her family. Each ticket costs $45.00 and there is a fee of $17.99. The total cost for tickets including the fee is $422.99. How many tickets does Eva buy?
45.00x +17.99 = 422.99 (Setup Equation)
45.00x = 405 (Subtract 17.99 from both sides)
x = 9 (Divide both sides by 45.00)
Answer:
9
Step-by-step explanation:
First, you write out the equation. We don't know how many tickets Eva bought, so it can be represented by x. Each ticket costs 45 dollars. The amount of tickets times 45 plus the fee will equal 422.99, so the equation will look like this:
45x + 17.99 = 422.99
Subtract 17.99 from both sides:
45x = 405
Divide 45 on both sides:
x = 9
Eva bought 9 tickets

paul and krystal spent 1 1/2 hours at the pool. for half of that time,they swam laps what equation can be used to find the amount of time they spent swimming laps
a.1 1/2 - 1/2
b.1 1/2 ÷1/2
c.1/2 × 1 1/2
d.1/2 + 1 1/2
Your answer is (C) !
The correct equation to find the amount of time they spent swimming laps is:
[tex]c. \( \frac{1}{2} \times 1 \frac{1}{2} \)[/tex]
To find the amount of time Paul and Krystal spent swimming laps, we need to determine what half of 1 1/2 hours is. This can be calculated by multiplying 1 1/2 by 1/2.
Let's look at the options:
a. [tex]\( 1 \frac{1}{2} - \frac{1}{2} \):[/tex] This would subtract 1/2 hour from 1 1/2 hours, which is not what we need.
b. [tex]\( 1 \frac{1}{2} \div \frac{1}{2} \):[/tex]This would divide 1 1/2 hours by 1/2, which is not what we need.
c. [tex]\( \frac{1}{2} \times 1 \frac{1}{2} \):[/tex]This is the correct operation, as it multiplies 1 1/2 hours by 1/2 to find half of the time.
d.[tex]\( \frac{1}{2} + 1 \frac{1}{2} \):[/tex] This would add 1/2 hour to 1 1/2 hours, which is not what we need.
So, the correct equation to find the amount of time they spent swimming laps is:
[tex]c. \( \frac{1}{2} \times 1 \frac{1}{2} \)[/tex]
Let's calculate it:
[tex]\[\frac{1}{2} \times 1 \frac{1}{2} = \frac{1}{2} \times \frac{3}{2} = \frac{3}{4} \text{ hours}\][/tex]
Therefore, Paul and Krystal spent [tex]\( \frac{3}{4} \)[/tex] hours (or 45 minutes) swimming laps.
What are the dimensions of this matrix?Help!!!
Answer:
The dimensions ⇒ 3 × 4
Step-by-step explanation:
* Any matrix has two dimensions
- Raw and column
- The dimensions very important in the operations on matrices
- We called the number of raw m and the number of column n
- We must write the number of raw before the number of column
- m × n is the dimensions of the matrix
* Example : If the dimension of a matrix is 2 × 3, that
means the matrix has 2 raw and 3 column
* Now lets look to our problem
∵ It has 3 raw and 4 column
∴ Its dimensions is 3 × 4

Antuan deposited $2590 into a 3 year CD at an interest rate of 2.3% compounded quarterly.
How much interest did the account earn after the three years? Show your work.
Answer:
the interest rate is $183.89 =~ $ 184
Step-by-step explanation:
In this question, Antuan deposited $2590 into a 3 year CD (Certificate of Deposit) at an interest rate of 2.3% compounded quarterly. We need to find the interest account earned after 3 years.
Formula used will be :
[tex] Interest = P ( 1 + r/n) ^ n ^ t - P[/tex]
Where
P= Principal amount
r= interest rate (in decimals)
n= no of times the interest is compounded
t = no of years
Here we are subtracting P because we only need interest amount and not the future value.
Using this formula and finding the value will be:
P= $2590
r = 2.3 % or 0.023
n = 4
t = 3
[tex]Interest = 2590 * ( 1 - 0.023 / 4) ^ 4^ * ^ 3 - 2590[/tex]
[tex]Interest= 2590 (1.071) -2590\\Interest= 2773.89 - 2590\\Interest= 183.89[/tex]
So the interest rate is $183.89 =~ $ 184
Each exterior angle of a regular n-gon shaped gazebo at Logan Park measures 22 1/2. Each exterior angle of a regular n-gon shaped gazebo at Cerro Park measures 15 15/23. By how many sides the gazebo at Logan Park is different from the gazebo at Cerro Park?
Answer:
the exterior angles of a polygon sum to 360
so the number of sides is 360/45
-PlushDna
Answer:
The difference in number of sides from one park to the next is 7
Step-by-step explanation:
For all polygon's the exterior angles combine to measure to 360 degrees. So to find the number of sides of each gazebo, we simply divide 360 by the measure of each individual exterior angle. We'll start with Logan Park.
360/22.5 = 16 sides
Now we can do the same with Cerro Park.
360/15.65 = 23 sides
Therefore, the difference in sides would be 7
23 - 16 = 7

Solve the triangle given two angles and one side.
Answer:
a = 102.05
b = 393.76
B = 93°
Step-by-step explanation:
The law of sines tells you ...
a/sin(A) = b/sin(B) = c/sin(C)
Since the sum of angles in a triangle is 180°, angle B must be ...
B = 180° -72° -15° = 93°
and the unknown sides must be ...
a = c/sin(C)·sin(A) = 375·sin(15°)/sin(72°) ≈ 102.05192
B = 93°
b = 375·sin(93°)/sin(72°) ≈ 393.75796

Answer:
50°
Step-by-step explanation:
As usual, the diagram is not drawn to scale.
The chord divides the circle into two arcs that have a sum of 360°. If we let "a" represent the measure of the smaller arc, then we have ...
a + (a+160°) = 360°
2a = 200° . . . . . . . . . . . subtract 160°
a = 100°
The measure of the angle at A is 1/2 the measure of the subtended arc:
acute ∠A = a/2 = (1/2)·100° = 50°
_____
Comment on this geometry
Consider a different inscribed angle, one with vertex V on the circle and subtending the same short arc subtended by chord AB. Then you know that the angle at V is half the measure of arc AB. This is still true as point V approaches (and becomes) point A on the circle. When V becomes A, segment VA becomes tangent line l, and you have the geometry shown here.
∠ABC is a 40∘ angle. Point A is at (7, 1) Point B is at (3, 2) Point C is at (8, -1) If ∠ABC is rotated 180∘ about the origin, what are the new points on the image and what is the new angle degree measurement?
Answer:
The new points would be (-7, -1), (-3, -2) and (-8, 1). The angle would not change
Step-by-step explanation:
When you rotate points by 180 degrees, you simply change the sign on the ordered pairs. This will give you the new points.
Also, spinning the points will not change the angle between them. Therefore it stays the same.

ANSWER
8π ft
EXPLANATION
The circumference of a circle is calculated using the formula C=πd.
Where d=8 is the diameter of the circle.
We substitute d=8 into the formula to obtain,
C=8π ft.
Because we are looking for the exact circumference, we leave the answer in terms of π.
Answer:
The correct answer is,
circumference = 8π feet
Step-by-step explanation:
Formula:-
Circumference of a circle = 2πr
Or circumference = πd
Where 'r' is the radius of circle and 'd' is the diameter of circle
It is given that, diameter of circle is 8 feet
To find the circumference
Here d= 8 feet
Circumference = πd = π * 8 = 8π feet

Using Cramer's Rule, the value of x in the given system of linear equations is approximately -5.09.
Explanation:To solve the system of linear equations using Cramer's Rule, we need to find the determinants of the coefficient matrix and the matrices obtained by replacing the corresponding column of the coefficient matrix with the constant matrix. Let's find the determinants:
Determinant of the coefficient matrix = |3 -4| = (3)(-6) - (4)(1) = -18 - 4 = -22
Determinant of the matrix obtained by replacing the x column = |-18 -4| = (-18)(-6) - (-4)(1) = 108 - (-4) = 112
Now, using Cramer's Rule:
x = Determinant of the matrix obtained by replacing the x column / Determinant of the coefficient matrix
x = 112 / -22 = -5.09
Therefore, the value of x in the given system of linear equations is approximately -5.09.
