Please give the correct value of c.​

Answer:

Charly has the better buy

Step-by-step explanation:

The unit cost is

=16.8/7

=$2.4

Her friend Charles bought 5 pounds of pretzels at the supermarket for $12.75

Unit cost

=12.75/5

=$2.55

Charly got the best deal because the unit cost per item is less than that of the friend

Answer:

4594.76 USD will be in the account on Burt's 18th birthday.

Step-by-step explanation:

Since interest rate is constant in time, we can use the definition of composite interest to determine how much money will be on Burt's 18th birthday, that is:

[tex]C = C_{o}\cdot \left(1+\frac{r}{100} \right)^{t}[/tex] (1)

Where:

[tex]C_{o}[/tex] - Initial amount, measured in US dollars.

[tex]C[/tex] - Current amount, measured in US dollars.

[tex]r[/tex] - Annual interest rate, measured in percentage.

[tex]t[/tex] - Time, measured in years.

If we know that [tex]C_{o} = 1250\,USD[/tex], [tex]r = 7.5[/tex] and [tex]t = 18[/tex], then the money in the savings account on Burt's 18th birthday is:

[tex]C = (1250\,USD)\cdot \left(1+\frac{7.5}{100} \right)^{18}[/tex]

[tex]C = 4594.76\,USD[/tex]

4594.76 USD will be in the account on Burt's 18th birthday.

Answer:

4%

Step-by-step explanation:

8 divided by 200 equals 0.04

0.04 times 100 equals 4

Therefore 4 percent of the people had a mild allgergic reaction.

Answer:

I. Not a function

II. Not a function

III. Yes, function

IIII. Yep!

(I messed up the numbering in the explanations, sorry 3 is 4 and 4 is 3)

Step-by-step explanation:

Hi!

For a function, every x value must have exactly 1 y value.

f(2) can't equal both 0 and 10. It can only equal 0 or 10. So, because of this, we have a test called the vertical line test. Basically, you drag a line through a graph, and if there is any x value that goes to two (or more) different y-values, then that graph is not the graph of the function.

Let me try to give a practical explanation.

I.

In this graph, everything looks fine until we reach x=6. (I'm assuming the graph goes by ones). Do you see the problem? Yep! x has two different y values.

y= 4 and y= 6.

So, this isn't a function. Why? Because there are two y values for each x value (aka, this doesn't pass the V.L.T)

II.

(1,2), (2,5) , (3,8) , (2,-5) (1,-2)

We have two groups of problem points.

(2,5) and (2,-5) and (1,2) and (1,-2)

Here, each x value goes to a different y value. Therefore, this isn't a function

III. y=x^2

This is your typical parabola. See the graph that I attached.

Notice that -2 and 2 both go to 4. Two different x-values going to the same y-value is fine, but one x can't go to to different y values.

IIII.

(-4,1) , (0,3) , (4,5) , (6,6)

Check 1: Does any x-value go to multiple y values? Nope! So, this is a function.

Answer:

A, B, C and E are true. Only D is false.

Step-by-step explanation:

Step-by-step explanation:

y - 8 = -8(x + 2)

y - 8 = -8x - 16

y = -8x - 8

The slope-intercept form is y = -8x - 8.

Answer:

y = -8x - 8

Step-by-step explanation:

First distribute the -8 into the parentheses

next get the the y by itself

add 8 to both sides and you get

y = -8x - 8

Answer:

0.70710678 is 2 root 1/2 simplified

Step-by-step explanation:

Given:

A test has 10 questions worth 100 points.

Points of each multiple choice question = 4

Points of each open-response question = 12

To find:

The number of multiple choice questions.

Solution:

Let x be the number of multiple choice questions and y be the open-response questions.

According to the question,

Total question : [tex]x+y=10[/tex]         ...(i)

Total points : [tex]4x+12y=100[/tex]      ...(ii)

Form (i), we get

[tex]y=10-x[/tex]         ...(iii)

Putting this in (ii), we get

[tex]4x+12(10-x)=100[/tex]

[tex]4x+120-12x=100[/tex]

[tex]-8x=100-120[/tex]

[tex]-8x=-20[/tex]

Dividing both sides by -8, we get

[tex]x=\dfrac{-20}{-8}[/tex]

[tex]x=2.5[/tex]

Since x is the number of multiple choice questions, so it cannot be a faction value.

Therefore, the number of multiple choice questions in test are either 2 or 3.

Answer:

The interest earned is $302.18

Step-by-step explanation:

Compound Interest

It occurs when the interest is reinvested rather than paying it out. Interest in the next compound period is earned on the principal sum plus previously accumulated interest.

The formula is:

[tex]{\displaystyle A=P\left(1+{\frac {r}{n}}\right)^{nt}}[/tex]

Where:

A = final amount

P = initial principal balance

r = interest rate

n = number of times interest applied per time period

t = number of time periods elapsed

The investment described in the question is of P=$600 at a rate of r=6%=0.06 for t=7 years compounded annually. The compounding period coincides with the time of interest rate, thus n=1.

Applying the formula:

[tex]{\displaystyle A=600\left(1+{\frac {0.06}{1}}\right)^{1*7}}[/tex]

[tex]{\displaystyle A=600\left(1.06}\right)^{7}}[/tex]

A = $902.18

The interest is:

I = A - P = $902.18 - $600 = $302.18

The interest earned is $302.18

Answer:

y=3x

Explanation: Since the line passes through (0,0), the y-intercept is 0. The rate of change is 3, which can be onserved if you you plot these points on a corrdinate graph. Therefore, the equation is y=3x.

Answer:

you're lazy count the squares

Step-by-step explanation:

i think i counted 73. You can count the squares again. Then that is the area cm^2

the perimeter i counted 64

Count the edges of the squares and you'll get perimeter. I counted roughly so count carefully.

Step-by-step explanation:

20 ÷ 2 = S

S represents the students that have straight A's the next year. You would simply divide the current number of students by 2 and it will give you half the student number you had before. And those are the students who still are getting straight A's.

it has gone up 4 lines and left -2 making it go for a (4,-2)
