Answers
Answer:
Step-by-step explanation:
hi sorry if this is wrong but the answer is Dena wants to make a birdhouse with the leftover wood. but She needs 105 3/5 of wood
Dena needs 1.15 centimeters more of wood is needed to make the birdhouse.
What is an expression?An expression is a combination of terms that are combined by using mathematical operations such as subtraction, addition, multiplication, and division.
A. To find the total length of wood left over, we need to add the lengths of all 5 pieces of wood.
We can represent each piece of wood with a fraction and then add all the fractions.
The total length of wood can be represented as:
12.7 + 26 3/10 + 15 4/5 + 21 1/4 + 19.2 = (12.7 + 26 + 15 + 21 + 19.2) + (3/10 + 4/5 + 1/4)
To simplify the expression, we can convert the mixed numbers (26 3/10 and 21 1/4) to improper fractions and convert the fractional part of decimals (3/10 and 4/5) to decimals:
12.7 + 26 3/10 = 12.7 + 26.3
15 4/5 = 15 + 0.8
21 1/4 = 21 + 0.25
3/10 = 0.3
4/5 = 0.8
So, the expression becomes:
12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2 = (12.7 + 26.3 + 15 + 0.8 + 21 + 0.25 + 19.2) + 0.3 + 0.8 = 104.45
Therefore, the total length of wood left over is 104.45 centimeters.
B. To determine how much more wood will be needed for the birdhouse, we can subtract the total length of wood left over from the required length:
105 3/5 - 104.45 = (105 + 0.6) - 104.45 = 105.6 - 104.45 = 1.15
Therefore, 1.15 centimeters more of wood is needed to make the birdhouse.

If two sectors have an area of 12π square units, and one sector is from a circle with radius 6 units, while the other is from a circle with a radius of 4 units, how do the central angles for these sectors compare?
Answers
Answer:
Thus, the ratio of the central angles is 4 : 9.
Step-by-step explanation:
Area, A = 12 π square units
radius, R = 6 units
radius, r = 4 units
Area of sector is given by
\(A=\frac{\theta }{360}\times \pi r^{2}\)
For first sector
\(12\pi=\frac{\theta }{360}\times \pi \times 6^{2}\\\\\theta = 120^{o}\)
For second sector
\(12\pi=\frac{\theta' }{360}\times \pi \times 4^{2}\\\\\theta' = 270^{o}\)
So, the ratio is
\(\frac{\theta}{\theta'}=\frac{120}{270} =4 : 9\)
Answer:
4 : 9
Step-by-step explanation:
Given:
Two sectors, each has an area of 12pi, but with radii r1=6 and r2=4 units.
Find ratio of central angles.
Solution:
Let A = central angle
Area of a sector = pi r^2 (A/360)
Since both sectors have the same area,
pi r1^2 (A1/360) = pi r2^2 (A2/360)
simplifying
A1 r1^2 = A2 r2^2
Therefore
A1 : A2 = r2^2 : r1^2 = 4^2 : 6^2 = 4 : 9

Answers
Answer:
C
Step-by-step explanation:
the greater than or less then symbol means at least and $425 means it has to be added in each month.
Answer:
25,000 ≥ 425x + 17,350
We know that x is the number of months. While 425 is the amount of money he is depositing every month. If he were to be spending it would have been a negative -17,350 ,which it is not. So, we can assume that 17,350 is the original amount of money he had in his account. At most would mean he could only have up to 25,000 which correspond with the "25,000 is greater than or equal to 425x + 17,350" So I think the answer is ..............................................................................................................................................B) Chris has $17,350 in his savings account. He will deposit $425 each month. What is x, the number of months Chris must deposit $425 to have at most $25,000 in his savings account?

-2/15 = -0.133
This gives you (-0.33)(-0.133)
Next, multiply both brackets together.
(-0.33)(-0.133) = appx. 0.044
Now that you have the product of the two brackets, calculate 5/6
5/6 = 0.833
Finally, sum it all up. Since the last two numbers are negative, we subtract them.

B) -(2x + 3) = -2x - 6
⇒ -2x - 6 = -2x - 6
C) 4(2x - 1) = 6x - 4 +2x

Step 2: 47
Step 3: 84
Step 4: 114
Step-by-step explanation:
Step 2: The width is 21, and the length is 36.
Sum is addition, so it would be 21 + 36.
21 + 36 = 47
Step 3: 47 x 2 = 84
Step 4: Perimeter is all around, whilst area is on the inside. The length is 21, so it is 21 + 21. 21 + 21 is 42. The width is 36, so it is 36 + 36, which is 72. 72 + 42 = 114.

Answers
Here are the pairs matched with their products:
- (-5)(4.2) matches with -21
- (-7)(-3) matches with 21
- (2.5)(-9) matches with -22.5
Pairs (4) and (5) do not have corresponding products in the given options.
(-5)(4.2) = -21
(-7)(-3) = 21
(4)(5) = 20
(2.5)(-9) = -22.5
So, the pairs of numbers and their products are as follows:
(-5)(4.2) = -21 matches with -21.
(-7)(-3) = 21 matches with 21.
(4)(5) = 20 matches with 20.
(2.5)(-9) = -22.5 matches with -22.5.

Determine the translation used to create the image. 5 units down 5 units up 1 unit down 1 unit up
Answers
Answer:
The translation used to create the image from polygon ABCD to polygon A' B' C' D' is 5 units down.
Step-by-step explanation:
You can see this by observing that all of the y-coordinates in A' B' C' D' are 5 units less than their corresponding y-coordinates in ABCD. Specifically, the y-coordinates of the vertices in ABCD are (-1, -5, -5, -1), and the y-coordinates of the vertices in A' B' C' D' are (-6, -10, -10, -6).
Therefore, the vertical shift or translation used to create the image is 5 units down.
Answer:
5 units down.
Step-by-step explanation:
To solve this question, we need to compare the coordinates of the corresponding vertices of the two polygons and see how they change. A translation is a type of transformation that slides a figure by a certain distance and direction without changing its size or shape. The rule of a translation can be written as (x, y) -> (x + h, y + k), where h and k are the horizontal and vertical shifts, we can see that:
A (1, -1) maps to A’ (1, -6), which means x stays the same and y decreases by 5.B (3, -5) maps to B’ (3, -10), which means x stays the same and y decreases by 5.C (7, -5) maps to C’ (7, -10), which means x stays the same and y decreases by 5.D (5, -1) maps to D’ (5, -6), which means x stays the same and y decreases by 5.We can see that all the vertices have the same change in their coordinates: x stays the same and y decreases by 5. This means that the translation used to create the image is 5 units down. The rule of this translation can be written as (x, y) -> (x, y - 5). Therefore, the answer is 5 units down.

Name a combination of coins that is 130% of the value of a dollar.
Answers
Answer:
5 quarters, 1 nickel
Step-by-step explanation:
A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.
What are percentages?A percentage is a number or ratio that can be expressed as a fraction of 100. If we have to calculate the percent of a number, divide the number by the whole and multiply by 100. Hence, the percentage means, a part per hundred. The word percent means per 100. It is represented by the symbol “%”
Given: A dollar and to find its 130% equivalent in the form of coins.
A nickel is worth 5 cents
A dime is worth 10 cents
A quarter is worth 25 cents
Now a dollar is equivalent to 100 cents
Thus 130% of a dollar is equivalent to
130/100 ×100 +100 =230 cents
Therefore a combination of 8 quarters which is equal to 200 cents and 2 dimes and 2 nickel is equal to 230 cents as
8×25+2×10+2×5=230 cents.
Hence, A combination of coins which is equivalent to 130% of a dollar is equal to 8 quarters,2 dimes and 2 nickels.
