I’m confused if someone can explain 15points

Answer:

D(0.10) + Q(0.25) = 10.45

Q = D + 25 (or Q - D = 25)

Step-by-step explanation:

D = number of dimes

Q = number of quarters

D(0.10) + Q(0.25) = 10.45

Q = D - 25 (or D - Q = 25)

We multiply the number of dimes she has by $0.10, because that is the worth of each dime, and we multiply the number of quarters she has by $0.25 because that is the worth of each quarter. We then set that equal to $10.45, the overall value of her coins.

Because she has 25 less dimes than quarters, the number of dimes she has should be 25 less than the number of quarters she has. So the number of quarters she has should be equal to the number of dimes she has plus 25.

Make 1 2/3 into a improper fraction. Now you have 5/3. 5/3-(1/3*5)=0

Therefore, 5x1/3=5/3=1 2/3

Answer:

This guy is wrong. 1 2/3 is equal to 5/3. But that is not the answer(like that dummy above said)

The Question is asking "How many 1/3's are in 1 2/3" (5/3)

The answer is 5, not 5/3's.

Answer:

6

Step-by-step explanation:

Place this digit in the quotient on top of the division symbol. Multiply the newest quotient digit (6) by the divisor 8 . Subtract 48 from 48 . The result of division of 48÷8 48 ÷ 8 is 6

The required, 49 divided by 8 gives 6 as the quotient and 1 as the remainder.

To divide 49 by 8, you can use long division to find the quotient.
Determine how many times the divisor (8) can fit into the new number (49). In this case, 8 goes into 49 six times. Subtract the result (48) from the number you brought down (49). 49 - 48 = 1. Write the result (1) below the line.  

    6
 _______

8 | 49

   -  48   (8 times 6)

   ______

        1   (Remaining 1 after subtracting)

Therefore, 49 divided by 8 gives 6 as the quotient and 1 as the remainder.

Step-by-step explanation:

(3,-5/2)

The midpoint of the line segment with these endpoints (-3, -8) and (9, 3) will be (0, 0.5).

Let AB be the line segment and C be the mid-point of line segment AB. Let the coordinate of point A (x₁, y₁), the coordinate of point B (x₂, y₂), and the coordinate of the mid-point (x, y).

Then the coordinate of the mid-point of the line segment is given as,

(x, y) = [(x₁ + x₂) / 2, (y₁ + y₂) / 2]

The endpoints of the line segment are given below.

(-3, -8) and (9, 3)

The midpoint of the line segment is calculated as,

(x, y) = [(-3 + 3) / 2, (-8 + 9)/ 2]

(x, y) = (0/2, 1/2)

(x, y) = (0, 0.5)

The midpoint of the line fragment with these endpoints (- 3, - 8) and (9, 3) will be (0, 0.5).

Step-by-step explanation:

Reflect over the Y axis, then translate (x+[-2], y+[-3])

The composition of transformations that map ABCD to EHGF will be [(x + 6), (y + 1)].

Change is referred to as transformation. As a result, a geometric transformation entails making modifications to any geometric shape.

Vertices of the quadrilateral ABCD having coordinate A,B,C,D are  (-5, 2),(-3, 4), (-2, 4),(-1, 2) respectively.

The image quadrilateral A'B'C'D' is formed by reflecting the supplied quadrilateral ABCD across the x-axis.

The rule for a point's reflection across the x-axis is:

(x, y) → (x , -y)

The picture point A' coordinates will be,

A(-5, 2) → A'(-5, -2)

Point E is produced by translating point A', as shown in the diagram. The rule for translating a point by h units right and k units up is as follows:

A'(x+h, y+k) → E(x', y')

By comparing coordinates of A' and E,

-5 + h = 1

h = 6

-2 + k = -1

k = 1

That is to say, the translation rule will be:

[(x + 6), (y + 1)]

Hence, the composition of transformations that map ABCD to EHGF will be [(x + 6), (y + 1)].

Answer:

1. 68%

2. 95%

3. 99.7

Step-by-step explanation:

Standard deviation of mean will be 68%, 95%, and 99.73% respectively.

A statistical rule known as the empirical rule, which is also known as the three-sigma rule or the 68-95-99.7 rule, states that almost all observed data for a normal distribution will be within three standard deviations of the mean or average.

Given according to the empirical rule, 68% of observations will fall within the first standard deviation (µ ± σ), 95% will fall within the first two standard deviations (µ ± 2σ), and 99.7% will fall within the first three standard deviations(µ ± 3σ) .

Hence SD  of mean will be 68%, 95%, and 99.73%

Step-by-step explanation:

just to sum all the given measurements:

19+31+15=65.

The number of hours Kelly drove longer than Joshua is 13/30 hours.

A fraction is written in the form of a numerator and a denominator where the denominator is greater that the numerator.

Example: 1/2, 1/3 is a fraction.

We have,

The number of hours driven by Kelly.

= 5/6 hours

The number of hours driven by Joshua.

= 2/5 hours

Now,

The difference between the number of hours driven by Kelly and Joshua.

= 5/6 - 2/5

= (25 - 12)/30

= 13/30

Thus,

Kelly drove 13/30 hours longer.

Step-by-step explanation:

Given

The above sample space

A = Event of an occurrence of 3 or 4 then a head

(a): List out the sample space:

The rolls of the dice come first, followed by the toss of the coin.

So, the sample space are:

[tex]S = \{(1,H),(2,H),(3,H),(4,H),(5,H),(6,H),(1,T),(2,T),(3,T),(4,T),(5,T),(6,T)\}[/tex]

The number of the sample space is:

[tex]n(S) = 12[/tex]

First, we list out the outcomes of event A

[tex]A = \{(3,H),(4,H)\}[/tex]

The number of outcome is:

[tex]n(A) = 2[/tex]

The probability of A is then calculated as:

[tex]P(A) = \frac{n(A)}{n(S)}[/tex]

[tex]P(A) = \frac{2}{12}[/tex]

Answer:

packages of buns = 1,260

packages of patties = 840

Jars of pickles = 1,680

Step-by-step explanation:

packages of buns = 3

packages of patties = 2

Jars of pickles = 4

Number of people = 420

Each person of the 420 people gets packages of buns, packages of patties, and jars of pickles in the ratio 3:2:4

packages of buns needed for 420 people = 3 × 420

= 1,260

packages of patties needed for 420 people = 2 × 420

= 840

Jars of pickles needed for 420 people = 4 × 420

= 1,680

packages of buns = 1,260

packages of patties = 840

Jars of pickles = 1,680

To feed at least 420 people minimum number of packages of buns, packages of patties, and jars of pickles needed is 1,260, 840, 1,680 respectively.
