Answer:

[tex]6\frac{1}{12}\ yd[/tex]

Step-by-step explanation:

The correct question is

Marcella bought 12 1/4 yards of ribbon. She uses 2 1/2 yards of ribbon for gift packages and 3 2/3 yards to tie balloons.

How many yards of ribbon does Marcella have left?

we know that

To find out how many yards of ribbon Marcella has left, add up the yards of ribbon used for the gift packages plus the yards of ribbon used to tie the balloons. and subtract this result from the total yards of ribbon bought by Marcella

so

[tex]12\frac{1}{4}-(2\frac{1}{2}+3\frac{2}{3})[/tex]

but first convert mixed number to an improper fractions

[tex]12\frac{1}{4}=\frac{12*4+1}{4}=\frac{49}{4}[/tex]

[tex]2\frac{1}{2}=\frac{2*2+1}{2}=\frac{5}{2}[/tex]

[tex]3\frac{2}{3}=\frac{3*3+2}{3}=\frac{11}{3}[/tex]

substitute in the expression above

[tex]\frac{49}{4}-(\frac{5}{2}+\frac{11}{3})[/tex]

[tex]\frac{49}{4}-(\frac{5*3+2*11}{6})[/tex]

[tex]\frac{49}{4}-(\frac{37}{6})[/tex]

[tex]\frac{3*49-37*2}{12}[/tex]

[tex]\frac{73}{12}\ yd[/tex]

Convert to mixed number

[tex]\frac{73}{12}\ yd=\frac{72}{12}+\frac{1}{12}=6\frac{1}{12}\ yd[/tex]

Final answer:

After calculating the total ribbon used in yards and subtracting it from the amount Marcella bought, we find that she has 5 13/42 yards of ribbon left.

Explanation:

To determine how many yards of ribbon Marcella has left, we need to subtract the total amount of ribbon she used from the initial amount she bought. Marcella originally bought 12/14 yards of ribbon. She used 2 1/2 yards for gift packages and 3 2/3 yards for tying balloons.

To make the subtraction easier, we'll first convert the mixed numbers to improper fractions. The mixed number 2 1/2 becomes 5/2 when we multiply 2 (the whole number) by the denominator (2) and then add the numerator (1), resulting in 4 + 1 = 5 over the original denominator 2. Similarly, 3 2/3 becomes 11/3 when we multiply 3 (the whole number) by the denominator (3) and then add the numerator (2), resulting in 9 + 2 = 11 over the original denominator 3.

Now, let's perform the subtraction:

First, simplify 12/14 to 6/7 by dividing both the numerator and denominator by 2.

Next, find a common denominator for all three fractions. The least common denominator for 2, 3, and 7 is 42.

Convert each fraction to have the denominator of 42.

12/14 yards (or 6/7 yards when simplified) is (6/7) * (42/42) which equals 36/42 yards.

2 1/2 yards as an improper fraction is 5/2, and when converted to have a denominator of 42, it becomes (5/2) * (21/21) which equals 105/42 yards. Similarly, 3 2/3 yards is 11/3, and when converted to have a denominator of 42, it becomes (11/3) * (14/14) which equals 154/42 yards.

Now subtract both of these amounts from 36/42 to find out how much ribbon Marcella has left:

36/42 - 105/42 - 154/42 = (36 - 105 - 154)/42 = -223/42

Because we cannot have a negative amount of ribbon, we realize we made an error. We should add the fractions instead of subtracting:

36/42 - (105/42 + 154/42) = (36/42) - (259/42)

This simplifies to -223/42, which is an improper fraction. To convert this back to a mixed number, we divide 223 by 42.

223 divided by 42 is 5 with a remainder of 13, so Marcella has 5 13/42 yards of ribbon left. However, we need the positive value since ribbon length cannot be negative. Thus, we keep the positive difference:

Marcella has 5 13/42 yards of ribbon remaining.

In conclusion, after Marcella uses ribbon for gift packages and tying balloons, she is left with 5 13/42 yards of ribbon.

Answer:

The amount of electricity bill is $52.60.

Step-by-step explanation:

Given:

Victoria whit used 578 kwh of electricity.

The rate is 9.1 cents per kw-hr.

Now, to find the amount of her electric bill.

Electricity used = 578 kwh.

Rate of electricity = 9.1 cents per kw-hr.

So, to get the amount we multiply the electricity used by the rate of electricity:

[tex]Amount\ of\ electric\ bill=Electricity\ used\times rate\ of\ electricity[/tex]

[tex]Amount\ of\ electric\ bill=578\ kwh\times 9.1\ cents[/tex]

[tex]Amount\ of\ electric\ bill=5259.8\ cents.[/tex]

Thus, the amount of electricity bill = 5259.8 cents.

Now, converting the amount from cents to $ by dividing:

$1 = 100 cents.

So, 5259.8 cents ÷ 100 = $52.60 .

therefore, the amount of electricity bill is $52.60.

Answer:

None of these

Step-by-step explanation:

A perpendicular bisector is a segment which intersects a given segment at a 90° angle, and passes through the given segment's midpoint. Since point T divides segment SU into two parts with lengths 46 and 62 units, VT is not a perpendicular bisector.

A median of the triangle is a segment joining a vertex to the midpoint of the opposite side. Since point T divides segment SU into two parts with lengths 46 and 62 units, VT is not a median.

An altitude of the triangle is a segment passing through a vertex and perpendicular to (i.e., forming a right angle with) a line containing the base (the side opposite the vertex). The diagram doesn't show the right angle at point T (VT is not perpendicular to SU), then VT is not an altitude.

Thus, option None of These is true.

Step-by-step explanation:

The GCF is the common "thing" in each one of the terms in our polynomial.  Since 3 doesn't divide evenly out of 10, 3 is not a GCF.  But b-squared is common in both.  So for part A. the GCF is b-squared.

part B.  Factor out the GCF:

[tex]b^2(3b+10)=0[/tex]

For part C. What are the solutions?  The solutions are found in the Zero Product Property which states that if the factors of a polynomial, when multiplied together, equal 0, then either one of the factors or both of the factors have to equal 0 because 0 times anything equals 0.  That means that

[tex]b^2=0[/tex] and/or 3b + 10 = 0

Solving the first equation:

[tex]b^2=0[/tex] and b = 0.

Solving the second equation:

3b + 10 = 0 and

3b = -10 so

Option A is correct, A shows a mapping diagram which represents a function from x → y

A relation is a function if it has only One y-value for each x-value.

A mapping diagram that represents a function from x to y is a diagram that shows a set of ordered pairs (x, y), such that each x-value has exactly one corresponding y-value

For option A, the ordered pairs are (4, 5)(5,5),(6,1),(8,2).

For each value of x there is only one value of y or else the values of x are not repeated so the diagram represents a function.

In other option the x has 2 values of y.

A mapping diagram that represents a function from x → y include the following: A. mapping diagram A.

In Mathematics, a function is typically used for defining and representing the relationship that exists between two or more variables such as an ordered pair.

This ultimately implies that, a function is typically used in mathematics for uniquely mapping an input variable (Set A) to an output variable (Set B).

Based on the mapping diagram shown above, we can reasonably infer and logically deduce that the inputs (4, 5), (5, 5), (6, 1), and (8, 2) are ordered pairs that represents a function because they indicate unique mappings of each input value to an output value.

Answer:

38 [tex]ft^{2}[/tex]

Step-by-step explanation:

We can see this figure as

WHOLE RECTANGLE - PORTION OF RECTANGLE CUT OUT

We know area of a rectangle is length * width

If this was the WHOLE RECTANGLE, the area would have been:

5 * 10 = 50 sq. ft.

The portion cut out is also a rectangle with dimensions:

Length = 6

Width = 5 - 3 = 2

Thus,

Area = 6 * 2 = 12 sq. ft.

So, the area of the figure is 50 - 12 = 38 sq. ft.

Prove that a triangle with the sides (a − 1) cm, 2√a cm and (a + 1) cm is a right angled triangle.

Answer:

∆ABC is right angled triangle with right angle at B.

Step-by-step explanation:

Given : Triangle having sides (a - 1) cm, 2√a and (a + 1) cm.  

We need to prove that triangle is the right angled triangle.

Let the triangle be denoted by Δ ABC with side as;

AB = (a - 1) cm

BC = (2√ a) cm

CA = (a + 1) cm  

Hence,

[tex]{AB}^2 = (a -1)^2[/tex] 

Now We know that

[tex](a- b)^2 = a^2+b^2 - 2ab[/tex]

So;

[tex]{AB}^2= a^2 + 1^2 -2\times a \times1[/tex]

[tex]{AB}^2 = a^2 + 1 -2a[/tex]

Now;

[tex]{BC}^2 = (2\sqrt{a})^2= 4a[/tex]

Also;

[tex]{CA}^2 = (a + 1)^2[/tex]

Now We know that

[tex](a+ b)^2 = a^2+b^2 + 2ab[/tex]

[tex]{CA}^2= a^2 + 1^2 +2\times a \times1[/tex]

[tex]{CA}^2 = a^2 + 1 +2a[/tex]

[tex]{CA}^2 = AB^2 + BC^2[/tex]

[By Pythagoras theorem]

[tex]a^2 + 1 +2a = a^2 + 1 - 2a + 4a\\\\a^2 + 1 +2a= a^2 + 1 +2a[/tex]

Hence, [tex]{CA}^2 = AB^2 + BC^2[/tex]

Now In right angled triangle the sum of square of two sides of triangle is equal to square of the third side.

This proves that ∆ABC is right angled triangle with right angle at B.

 0.580   0.805   1.160   1.085   1.345   1.470

We can order the data on increasing way:

[1] 0.58 0.68 0.72 0.89 1.01 1.16 1.28 1.33 1.36  1.45 1.47

And for this case we got this:

The minimum on this case is: [tex]Minimum =0.58[/tex]

The maximum would be: [tex]Maximum = 1.47[/tex]

In order to find the median we need to find the value on the 6 position from the data ordered, and we got:

[tex]Median = 1.16[/tex]

And in order to obtain the boxplot we can use R to grapth the boxplot"

> boxplot(data,main="Boxplot")

And the result is on the figurea attached.

The five-number summary of the given data set is 0.58, 0.72, 1.16, 1.36, 1.47, representing the minimum, first quartile, median, third quartile, and maximum values of the data. These can be used to create a box plot to visualize the data.

The five-number summary of a data set includes the minimum, first quartile, median, third quartile, and maximum values of the data set. Here's how we can find those for the given radiation absorption rates:

So, the five-number summary is: 0.58, 0.72, 1.16, 1.36, 1.47.
