Layla and Amelia are making bracelets. It takes Layla 45 minutes to make 9 bracelets on her own. Together, Layla and Amelia can make 9 bracelets in 20 minutes. How long will it take Amelia to make 9 bracelets?

Answer:

535 is not equal to 360

Step-by-step explanation:

the total interior angle = 360 degree

180-80=100

180-80=100

180-75=105

180-70=110

180-60=120

100+100+105+110+120= 535 which is not equal to 360. Since the total interior angle is not 360, Jay's measurements are wrong .

The given set A = {10, 11, 12, 13}, has the cardinal number n(A) = 4, and it has 15 non-empty subsets.

In the question, we are given a set A = {10, 11, 12, 13}.

We are asked for the cardinal number of the set n(A).

Also, we are asked for the number of non-empty subsets of A.

The cardinal number of any set A is given as n(A), which represents the number of elements in set A.

For the given set A = {10, 11, 12, 13}, the number of elements are 4.

Thus, the cardinal number of the set A is, n(A) = 4.

The number of non-empty subsets of any set A, with cardinal number n, is given by the formula, 2ⁿ - 1.

The given set A = {10, 11, 12, 13}, has the cardinal number n(A) = 4.

Thus, the number of non-empty subsets of set A = 2⁴ - 1 = 16 - 1 = 15.

Thus, the given set A = {10, 11, 12, 13}, has the cardinal number n(A) = 4, and it has 15 non-empty subsets.

Recall

x+2y=13. equ.1

3x-5y=6. equ.2

equ.1=

x-2y=13

x=13-2y. equ.3

Substitute 'x' into equ.2

therefore y=3

Substitute 'y' into equ.1, equ.2 or equ.3

Recall equ.3

We need 251.33 gallons of the milk with 7% butterfat and 126.67 gallons of the milk with 4% butterfat to make the desire 378 gallons.

Given,

The amount of milk needed in the dairy = 378 gallons

The quantity of butterfat needed in the milk = 6%

We have to find the amount of milk containing 7% and 4% butterfat used to obtain 378 gallons:

Now,

The amount of milk containing 7% butterfat = x gallons.

The amount of milk containing 4% butterfat = y gallons.

Now, we can have the equation as:

x + y = 378

Percentage of butterfat needed = 6%

0.07x + 0.04y = 0.06 x 378

0.07x + 0.04y = 22.68

Solve for x and y :

x + y = 378        ---------------------- (1)

0.07x + 0.04y = 22.68  -------------- (2)

From Equation (1) :

x + y = 378

x = 378 - y ------------------ Substitute into (2)

0.07(378 - y) + 0.04y = 22.68

26.48 - 0.7y + 0.04y = 22.68

26.48 - 0.03y = 22.68

26.48 - 22.68 = 0.03y

3.8 = 0.03y

y = 3.8 / 0.03

y = 126.67 ---- sub into (1)

x + y = 378

x + 126.67 = 378

x = 378 - 126.67

x = 251.33

Therefore,

Amount of milk containing 7% butterfat = x = 251.33 gallons

Amount of milk containing 4% butterfat = y = 126.67 gallons.

That is,

We need 251.33 gallons of the milk with 7% butterfat and 126.67 gallons of the milk with 4% butterfat to make the desire 378 gallons.

The number of tickets for general admission is 75 and with student id's is 105.

Given that,

Tickets of a program at college cost ​$5 for general admission or ​$4 with a student ID.
180 people paid to see a performance and ​$795 was​ collected, how many of each type of ticket were​ sold is to be determined.

Here,
Number of admission with general admission = x
Number of admission with college id = y

According to the given conditions,
x + y = 180
x = 180 - y      - - - - - - (1)
5x + 4y = 795   - - - - - (2)

Now put the value of the equation in equation 2
5 (180 - y) + 4y = 795
900 - 5y + 4y = 795
-y = 795 - 900
-y = -105
y = 105

Now put y in equation 1

x = 180 - 105
x = 75

Thus, the number for tickets with general admission is 75 and with student id is 105.

The required measure of the angle of the trapezoid is 50° and 101°.

The angle can be defined as the one line inclined over another line.
Where angle measures in degree and radian.

Here,
For trapezoid one 1.
The Sum of the adjacent angle is 180°.
So, 130 + ∠C = 180
∠C = 180 - 130
∠C = 50

For trapezoid 2.
Sum of all the angle should be equal to 360°
but ∠Q = ∠S
110 + 48 + 2∠Q = 360
∠Q = 101°

The question is asking :

what number multiplied by the least amount would give me the greatest amount?? Let that number be x, so we can say:

least amount * x = greatest amount

From the plot, we can see that the least amount is 1/8 inches

The greatest amount is 2 inches now we can put it into the formula and find x:

1/8 * x = 2

x = 2/(1/8)

x = 16

Reason:

Your teacher wants you to find out how many elements are in set A.

Focus on the numerators only.

That sequence is 1,2,3,..., 37,38 which consists of 38 numbers.

If you wanted to focus on the denominators, then we go from 3 to 40 which is a gap of 40-3 = 37, but then add on 1 to account for the first item. So we get to 37+1 = 38.

The required measure of the angle K  is 110° and the simplified value of the x is 6.

Here,
In a parallelogram sum of the adjacent angle is 180°, So
18x + 2 + 70 = 180
18x + 72 = 180
18x = 180 - 72
18x = 108
x = 6

Now, angle k
= 18x + 2
= 18 * 6 + 2
= 110

Thus, the required measure of the angle K  is 110° and the simplified value of the x is 6.

Answer:

B

Step-by-step explanation:

The domain of a graph is its turning point

a = amount invested at 6.3%

how much is 6.3% of "a"? (6.3/100) * "a", namely 0.063a.

b = amount invested at 7.1%

how much is 7.1% of "b"? (7.1/100) * "b", namely 0.071b.

we know the total amount invested is $15,000, so whatever "a" and "b" might be, we know that a + b = 15000.

we also know that the yielded amount in interest is $1050, so if we simply add their interest, that'd be 0.063a + 0.071b.

[tex]\begin{cases} a + b = 15000\\ b = 15000 - a\\[-0.5em] \hrulefill\\ 0.063a+0.071b=1050 \end{cases} \\\\\\ \stackrel{\textit{substituting on the 2nd equation}}{0.063a+0.071(\underset{b}{15000-a})=1050}\implies 0.063a+1065-0.071a=1050 \\\\\\ 0.063a-0.071a=-15\implies -0.008a=-15\implies a=\cfrac{-15}{-0.008} \\\\\\ \boxed{a = 1875}\hspace{15em}\boxed{\stackrel{15000~~ - ~~1875}{b = 13125}}[/tex]
