abdel purchased a candy bar for $1.47 and ice cream for $3.48. How much change did he receive if he paid a ten-dollar bill.

Answer:

I need the answer choices

Step-by-step explanation:

Answer:

The answer is C.

Have a good day!

Answer:

I agree with both of them

Step-by-step explanation:

A dozen is 12 muffins. Therefore, you pay $3.00 for 12 muffins.

We know that you pay $3.00 for 12 muffins we need to find out how much EACH muffin cost. For that we need to divide $3.00 by 12 which is 0.25.

Now we need to know how much it will cost us for 16 muffins. We use our equation 16*0.25 which is 4. Elena said she will pay 4 so she is right.

Andre said he will buy 8 muffins so we use our equation again 8*0.25 which is 2. He said he will pay 2 so he is right.

Step-by-step explanation:

Answer:

3 11/16 pounds

Step-by-step explanation:

Lynne bought a bag of grapefruit, 1 5/8 pounds of apples, and 2 3/16 pounds of bananas. The total weight of her purchases was 7 1/2 pounds. How much did the bag of grapefruit weigh?'

The Total weight = Weight of grape fruits + Weight of Apples + Weight of Bananas

Let the weight of the grape fruit = x

7 1/2 = x + 1 5/8 + 2 3/16

x = 7 1/2 - (1 5/8 + 2 3/16)

Lowest Common Denominator = 16

x= 7 1/2 - 3 + ( 10+ 3/16)

x = 7 1/2 - 3 + (13/16)

x = 7 1/2 - 3 13/16

Lowest Common Denominator = 16

x= 4 (8 - 13/16)

x = 4 (-5/16)

x = 3 11/16 pounds

Therefore, the bag of grapefruits weighed 3 11/16 pounds

Answer:

x+x+2+x+4=318

3x+6=318

3x=312

x=104

The first number is 104.

Step-by-step explanation:

========================================================

Explanation:

n = some integer

2n = some even integer

2n+2 = next integer after 2n

2n+4 = next integer after 2n+2

The sequence {2n, 2n+2, 2n+4} represents three consecutive even integers. One follows right after another. A more concrete example of consecutive even integers could be something like {2,4,6} or {8,10,12}. The goal is to find which set like this has their numbers add to 318.

We could guess-and-check our way to the answer. In other words, use trial and error. However, a much more efficient way is to use algebra.

Let's add up the three number expressions of 2n, 2n+2, and 2n+4 to get

(2n)+(2n+2)+(2n+4) = (2n+2n+2n) + (2+4) = 6n+6

The three numbers add to 6n+6

This sum must be 318. Let's set 6n+6 equal to 318 and solve for n

6n+6 = 318

6n = 318-6

6n = 312

n = 312/6

n = 52

-----------------------

If n = 52, then,

Note the sequence 104, 106, 108 are all even numbers where they follow right after one another. This shows they are consecutive even numbers.

Furthermore, note how,

104+106+108 = 318

which confirms our answer

Answer:

A function is a relation that assigns exactly one output value to one input value.        

Answer:

4 dollars per pair of socks.

Step-by-step explanation:

You already determined that x and y have a proportional relationship, as y is four times the x value. Therefore, when x is 1, that means one pair of socks will be four dollars.

Another way to solve this is by forming a linear equation.

y = 4x

Any number plugged into x to represent pairs of socks will give the cost, y.

For example: y = 4(7), which simplifies to y = 28.

This means that for every one pair of socks, it costs four dollars.

Answer:

yes and $4

Step-by-step explanation:

7*4=28

11*4=44

13*4=52

15*4=60

Answer:

The plant grew [tex]12\frac{1}{14}[/tex] inches

Step-by-step explanation:

Operations with Fractions

Felipe planted seeds for a science project. One of the plants grew 6 2/7 inches in the first week and 5 11/14 inches in the second week.

We are required to find the total growth during the two weeks. We have to find the sum of:

[tex]6\frac{2}{7}+5\frac{11}{14}[/tex]

Let's convert both fractions to improper form:

[tex]6\frac{2}{7}+5\frac{11}{14}=6+\frac{2}{7}+5+\frac{11}{14}[/tex]

Adding the integers:

[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{2}{7}+\frac{11}{14}[/tex]

Now we find the LCM of 7 and 14 is 14, thus:

[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{4}{14}+\frac{11}{14}[/tex]

[tex]6\frac{2}{7}+5\frac{11}{14}=11+\frac{15}{14}=11+\frac{14+1}{14}[/tex]

[tex]6\frac{2}{7}+5\frac{11}{14}=11+1+\frac{1}{14}[/tex]

[tex]6\frac{2}{7}+5\frac{11}{14}=12+\frac{1}{14}[/tex]

Rewriting as a mixed number:

The plant grew [tex]12\frac{1}{14}[/tex] inches

Answer:

-12° C

Step-by-step explanation:

Temperature at 8 a.m.: -3° C

From 8 a.m. to 1 p.m. the temperature went up 5° C.

-3° C + 5° C = 2° C

Temperature at 1 p.m.: 2° C

By 6 p.m. the temperature was 2° C colder than at 1 p.m.

2° C - 2° C = 0° C

Temperature at 1 p.m.: 0° C

The temperature decreased 3° C per hour from 6 p.m. to 10 p.m.

From 6 p.m. to 10 p.m., it's 4 hours. The temperature decreased 3° C per hour for 4 hours. 4 * 3° C = 12° C. The temperature went down 12° C altogether from 6 p.m. to 10 p.m.

0° C - 12° C = -12° C

Temperature at 10 p.m.: -12° C

Answer: -12° C

Answer:

Step-by-step explanation:

2 real roots and 2 complex

Following are the solution to the given polynomial equation:

Given:

Polynomial equation: [tex]\bold{n(x) = 3x^4 - 9x^3 + x^2 -3x}[/tex]

Factor: [tex]\bold{(x -3)}[/tex]

To find:

A number of roots for the polynomial n(x).

Solution:

Polynomial equation: [tex]\bold{n(x) = 3x^4 - 9x^3 + x^2 -3x}[/tex]

[tex]\to \bold{(x -3)=0}\\\\\to \bold{x =3}\\\\[/tex]

Putting the of x into the given Polynomial function:

[tex]\to \bold{n(3) = 3(3)^4 - 9(3)^3 + (3)^2 -3(3)}\\\\\to \bold{n(3) = 3\times 81 - 9\times 27 + 9 -3 \times 3}\\\\\to \bold{n(3) = 243- 243 + 9 -9}\\\\\to \bold{n(3) = 0}\\\\[/tex]

Let divide the Polynomial function by the factor:

[tex]\to \bold{\frac{3x^4 - 9x^3 + x^2 - 3x}{x-3}}\\\\\to \bold{\frac{ x(3x^3 - 9x^2 + x - 3)}{x-3}}\\\\\to \bold{\frac{ x(3x^2(x - 3)+1(x - 3))}{x-3}}\\\\\to \bold{\frac{ x(x - 3) (3x^2+1)}{x-3}}\\\\\to \bold{x(3x^2+1)}\\\\[/tex]

So, the factors are [tex]\bold{x, (x-3),\ and \ (3x^2+1)}[/tex].

Calculation of the roots:

[tex]\bold{x=0 \ \ \ \ \ \ \ \ \ \ \ \ \ x-3=0 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 3x^2+1 =0}\\\\\bold{x=0 \ \ \ \ \ \ \ \ \ \ \ \ \ x=3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ 3x^2 = -1}\\\\\bold{x=0 \ \ \ \ \ \ \ \ \ \ \ \ \ x=3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x^2 = -\frac{1}{3}}\\\\\bold{x=0 \ \ \ \ \ \ \ \ \ \ \ \ \ x=3 \ \ \ \ \ \ \ \ \ \ \ \ \ \ \ x^2 = (- \sqrt{\frac{1}{3}})^2}\\\\[/tex]

Therefore the final answer is "Option A".

Answer:

65 degrees

Step-by-step explanation:

The question is not complete but we can assume that m<4 and m<8 are complementary i.e they both act at right angle.

If the both act at right angle, then m<4 + m<8 = 90

Given

m<4 = 25°

Substitute into the formula

m<4 + m<8 = 90

m<8 = 90 - m<4

m<8 = 90 - 25

m< 8 = 65 degrees

Hence the measure of m<8 is 65 degrees

Note that we assumed that both angles acts at right angles

Answer:

See Below.

Step-by-step explanation:

The sum of an A.P. is given by:

[tex]\displaystyle S_n=\frac{n}{2}(a+x_n)[/tex]

Where n is the number of terms, a is the initial term, and xₙ is the last term.

Therefore:

[tex]\displaystyle S_{30}=\frac{30}{2}\Big(a+x_{30}\Big)=15(a+x_{30})[/tex]

And likewise:

[tex]\displaystyle S_{20}=\frac{20}{2}\Big(a+x_{20}\Big)=10(a+x_{20})\\\\ S_{10}=\frac{10}{2}\Big(a+x_{10}\Big)=5(a+x_{10})[/tex]

Substitute:

[tex]15(a + x_{30}) = 3(10 (a + x_{20}) - 5(a + x_{10} ))[/tex]

Distribute:

[tex]15a+15x_{30}=30a+30x_{20}-15a-15x_{10}[/tex]

Simplify:

[tex]15x_{30}=30x_{20}-15x_{10}[/tex]

Simplify:

[tex]x_{30}=2x_{20}-x_{10}[/tex]

The nth term for an A.P. is:

[tex]x_n=a+d(n-1)[/tex]

Where a is the initial term and d is the common difference.

So, it follows that:

[tex]x_{30}=a+d(30-1)=29d+a\\ x_{20}=a+d(20-1)=19d+a\\ x_{10}=a+d(10-1)=9d+a[/tex]

Therefore:

[tex]29d+a=2(19d+a)-9d-a[/tex]

Which follows that:

[tex]29d+a=38d+2a-9d-a\\ \\ 29d=29d \\\\ d\stackrel{\checkmark}{=}d[/tex]

Answer:

60.6 on delta math

Step-by-step explanation:

The rate of the flow will be 1.12 x 10⁻⁴ cubic meters per meter.

The rate of the flow of the fluid is defined as the volume of the fluid through a confined space or cross-section in a unit of time. The unit of the rate of flow is gallons per minute or cubic meter per minute.

Given that water flows through a pipe at a rate of 89 quarts per hour the value of the rate of flow in cubic meters per month will be calculated as below:-

1 quartz = ( 1 / 1056.688) cubic meters

1 quartz = ( 89 / 1056.688)

1 quartz = 0.08 cubic meters

1  quartz per hour = 0.08 / ( 24 x 30) cubic meters per month

1  quartz per hour =1.12 x 10⁻⁴ cubic meters per month

Therefore, the rate of the flow will be 1.12 x 10⁻⁴ cubic meters per meter.
