Karla has spent $39 on food. She bought milk, cheese, and meat. The milk cost half as much as the cheese and the meat cost four times as much as the cheese. Which equation would help you find the cost of the cheese?

Let c = the amount spent on cheese

Click on the correct answer:

1)C+ 4c/5c=39

2)C+2c + 4c = 39

3)C+.5c + 4c = 39

4)C(.5c+ 4c) = 39

Answer:

100

Step-by-step explanation:

1/10(3n+50)=35

3n+50=35*10

3n+50=350

3n=350-50

3n=300

n=300/3

n=100

Answer:

24 units^2. :)

Answer:

She would make $35.

Step-by-step explanation:

If you do 10 x 3.5, you will get the answer of $35.

Answer:

$30

Step-by-step explanation:

She would be getting paid by the HOUR, and she has worked 3.5 hours. If she gets paid every HOUR, that means that she would be paid three times when working 3.5 hours. The answer would be $30.

The person who wrote the question might want $35 dollars as the answer, but logically the answer should be $30.

Answer:

Step-by-step explanation:

The equation of the line in slope-intercept form:  y = mx + b, where m is a slope and b is y-intercept

Slope of  line that passes through two given points:  [tex]m=\dfrac{y_2-y_1}{x_2-x_1}[/tex]

(0, 8)    ⇒    x₁ = 0,  y₁ = 8

(3, 3)      ⇒    x₂ = 3,  y₂ = 3

[tex]\bold{m=\dfrac{3-8}{3-0}=\dfrac{-5}3=-\dfrac53}[/tex]

b = 8

Therefore the equation:   y = -⁵/₃x + 8

Step-by-step explanation:

Answer:

1.39

Step-by-step explanation:

Given the quadratic equation :

2x^2+3x-8 = 0

We could apply the quadratic equation formula :

a = 2 ; b = 3, c = - 8

The formula is stated as :

-b±sqrt(b² - 4ac)/2a

To save computation tune, we could use a calculator :

The roots are : - 2.886 ; 1.386

The positive solution rounded to the nearest hundredth is : 1.39

Answer:

500

Step-by-step explanation:

I believe the answer is D) The mean cannot be determined from the available information.

The mean in math means the sum of all the numbers divided by how many numbers there are. There is no information about how many numbers there are nor any information of which numbers exist and which numbers don't.

The data set only tells us the first number, last number, and median-- things a box-and-whisker plot would tell us; perhaps a different way of representing data would work better to help us find the median like a dot plot or a bar graph.

If this is incorrect, please, don't refrain to tell me. Thank you.

Answer:

so I'm not 100% sure but in these types of questions you are supposed to divide

so you have a pack of 24 bottles for 7.99

so you would do 7.99÷24 = 0.33

then to check it you can multiply

0.33× 24 bottles and it gives you 7.93 which is super close to 7.99 anyway I hope this helps ...

Answer:

Here we can not see the options, so i will answer in a general way.

When we have a function y = f(x), we define:

x as the input

y as the output.

so f(x) is some kind of "machine", in wich we put an input x, and the "machine" does something and returns an output y.

In, this case, we have:

y = f(x) = 4*x - 3

then if we give this function different inputs, we will get different ouputs.

for example, if we use the input x = 0, then the output is:

y = f(0) = 4*0 - 3 = -3

Then if we made a table for inputs and outputs, we will have the data:

[tex]\left[\begin{array}{ccc}inp&out\\x&y\\0&-3\end{array}\right][/tex]

We can rewrite this table in a general way as:

[tex]\left[\begin{array}{ccc}inp&out\\x&4*x - 3\end{array}\right][/tex]

This means that for every input x, the output is always 4*x - 3.

To complete this type of tables, we usually use different values of x, for example here I will use some different ones:

y = f(3) = 4*3 - 3 = 12 - 3 = 9

y = f(10) = 4*10 - 3 = 40 - 3 = 37

y = f(-1) = 4*-1 - 3 = -4 - 3 = -7

Then we will have a table like:

[tex]\left[\begin{array}{ccc}inp&out\\3&9\\10&37\\-1&-7\end{array}\right][/tex]

Concluding, the thing that will always represent the output of our function is: 4*x - 3.

Answer:

$2.24

Step-by-step explanation:

Since we are trying to find a percentage of something, we can multiply whatever we're trying to find a percentage from by 0.X where X is equal to the number of the percentage. So in this case it's 15%. We can multiply $14.90 by 0.15 and we get 2.23500. Since we cannot have 2.235 dollars, we must round up decimal places.

The tip would be 2 dollars and 24 cents. ($2.24).

Horace measured a circular lid and found d, the diameter, was 8 inches and C, the circumference, was 25 inches. Which expression represents an approximate value for pi?

Answer:

pi = 3.125

Step-by-step explanation:

We are given;

Diameter; d = 8 inches

Circumference; C = 25 inches

Formula for circumference of a circle is;

C = πd

We are trying to find the value for pi(π)

Thus; π = C/d

π = 25/8

π = 3.125

Answer:

57

Step-by-step explanation:

if 1 = 123 degrees, and the angles add up to 360, then 6 would be 57. Because you would do 123 is 5 and 8, and so 246 is adding those angles. So now you have 7 and 6. 360 - 246 is 114, and since 7 and 6 are equal, just divide that by 2

Answer:

18sqrt5  or 40.249

Step-by-step explanation:

by pythagorean theorem

Hypotenous^2=altitude^2+base^2

c^2=a^2+b^2

c^2=(18)^2+(36)^2

c^2=324+1296

c^2=1620

taking sqrt root

c=18sqrt5=40.249

Answer:

in right angled triangle BCD

by using Pythagoras law

P²+B²=H²

A²+B²=C²

36²+18²=x²

x=√1620=18√5m

x=18√5 m is your answer

Step-by-step explanation:

Answer:

Purple Diamond = 2  Green Moon = 7.5 Pink Trapezium = 30

Step-by-step explanation:

T = Pink Trapezium

D = Purple Diamond

M = Green Moon

Line 1 = T = 30 x 1 = 30

Line 2 = (D x D) x (M) = (2x2) x (7.5) = 4 x 7.5 = 30

The key is the weight of the line multiples to 30

Just like graphs do with x/y

If x is horizontal then y is vertical

= x/y we get the gradient which is the same as division or dividing 30/30 = 1 being the base weight amount

and same as 30/7.5 = 4 and simplifying 4 to (2 x 2)that means an easier way to see the number of (2x2) being the base weight = 1 x 2  then 1 x 2 then as we have found 4 its simplification we can divide it into 30 to show 30/4 = 7.5 for the Moon or for (M) above.

The 4 number is simplification and (+ 2 )(+ 2) is its factorization before it turns to 30 to show 30 = (2 x 2 x 7.5)  or 2^2 x 7.5 = 30. Etc. Etc.

Question:

The shaded portion of the bar model in Part A shows 3/8. What percent is equivalent to 3/8? Enter the correct answer in the box.

Answer:

The equivalent is 37.5%

Step-by-step explanation:

Given

[tex]\frac{3}{8}[/tex]

Required

The equivalent

The model is not shown, but the question can still be solved.

We have:

[tex]\frac{3}{8}[/tex]

Multiply by 100%

[tex]\frac{3}{8} = \frac{3}{8} * 100\%[/tex]
