When Isabel makes salad dressing, she likes to make it with 3 parts olive oil to 2 parts balsamic vinegar. If Isabel has 120 milliliters of olive oil (and a sufficient supply of balsamic vinegar), how many milliliters of salad dressing can she make? Thanks!
Answers
Let's say Olive oil = O, Balsamic Vinegar = B, Salad Dressing = S
For the salad dressing she uses 3 parts olive oil to 2 parts balsamic vinegar
So we can say for every 3 ml of olive oil, she needs 2ml of balsamic vinegar
We know she has 120ml of olive oil, so first step is to find how much balsamic vinegar she will be using.
Remember, for every 3 ml of Olive Oil, she needs 2ml of Balsamic Vinegar .
if you do 120 divided by 3 = 40
So she is making 40 times the amount of salad dressing.
This means you need to multiply the amount of balsamic vinegar by 40.
B = 40 times 2 = 80 ml
So now for the dressing we know :
She uses 120 ml of olive oil and 80 ml of balsamic vinegar.
So to find how many ml of salad dressing she can make, you just add the two.
S = O + B = 120 + 80 = 200 ml
Using proportions, it is found that she can make 80 milliliters of salad dressing.
This question is solved by proportions, using a rule of three.For 3 parts of olive oil, she uses 2 parts of balsamic vinegar. How many millilitres of vinegar when she has 120 millilitres of olive oil?The rule of three is:
3 parts of olive oil - 2 parts of balsamic vinegar.
120 ml - x ml
Applying cross multiplication:
\(3x = 2(120)\)
\(3x = 240\)
\(x = \frac{240}{3}\)
\(x = 80\)
She can make 80 milliliters of salad dressing.

Answers
Answer:
Step-by-step explanation:
Ice sheets have one particularly special property. They allow us to go back in time and to sample accumulation, air temperature and air chemistry from another time[1]. Ice core records allow us to generate continuous reconstructions of past climate, going back at least 800,000 years[2].
Ice coring has been around since the 1950s. Ice cores have been drilled in ice sheets worldwide, but notably in Greenland[3] and Antarctica[4, 5]. High rates of snow accumulation provide excellent time resolution, and bubbles in the ice core preserve actual samples of the world’s ancient atmosphere[6].
What is the value of the expression 50 - (5 + 2)2 + 6?
Answers
Answer:
I believe it's 42
Step-by-step explanation:
Replace each letter in the expression with the assigned value.
First, replace each letter in the expression with the value that has been assigned to it. To make your calculations clear and avoid mistakes, always enclose the numbers you're substituting inside parentheses. The value that's given to a variable stays the same throughout the entire problem, even if the letter occurs more than once in the expression.
However, since variables "vary", the value assigned to a particular variable can change from problem to problem, just not within a single problem.
Perform the operations in the expression using the correct order of operations.
Once you've substituted the value for the letter, do the operations to find the value of the expression.

The volume of a triangular pyramid is 13.5 cubic meters. What is the volume of a triangular prism with a congruent base and the same height?
Answers
Answer:
The prism is 3 by 3 by 1.5.
Step-by-step explanation:
The prism has a length x and a width x. Since it is a square at the base both length and width are the same amount x. The height is "half the length of one edge of the base". Since the base is x, this makes it 1/2x.
The volume's prism is found using V = l*w*h. Substitute and simplify.
13.5 = x*x*1/2x
13.5 = 1/2 x^3
27 = x^3
3 = x
The prism is 3 by 3 by 1.5.

one side of an isosceles triangle is three times as long as another side of the triangle. If the perimeterof the triangle is 140, then what is the length of the base of the triangle?
Answers
Answer:
20
Step-by-step explanation:
P, perimeter of triangle = a + b + c
We're given P = 140 and it is an isosceles triangle.
We can change P to be 2a + b since 2 sides are equal in an isosceles
So, 140 = 2a + b
One side is 3x longer than the other. The equal sides in the triangle can not be 3x longer than each other since it is equal.
And the isosceles sides are longer than the 1 base side.
So if a = our isosceles sides, and b is our base side, than a is 3x our base side which can be written as a = 3b
Now, 140 = 2(3b) + b, and we can now solve
140 = 6b + b => 140 = 7b
20 = b
Our base length is 20.

In parallelograms opposite angles are congruent and angles that are on the same line are supplementary
This means that ∠TUR and ∠URS are supplementary angles
Supplementary angles have a sum of 180°
That being said we can find the missing angle ( ∠ URS ) by subtracting the measure of the given angle ( ∠TUR which has a measure of 160° ) from 180
so ∠URS = 180 - ∠TUR ( 160 )
180 - 160 = 20
Hence, ∠URS = 20°

x=0
Step-by-step explanation:
x°+65°+109°+136°=310°
we know that this whole equation equals 310.
so we add all the numbers equaling x+174+136=310 : x+310=310
x clearly equals 0 and even then you can subtract 310 from both sides which still gives you 0.

Step-by-step explanation:
x°+ 65° + 109° + 136° = 310°
Add all of the degrees on the left side together.
x° + 310° = 310°
Subtract 310° from both sides.
x° + 310° = 310°
- 310° - 310°
+ 310° and - 310° cancel out. 310° - 310° is 0.
x° = 0°
So, x° = 310° is your answer.

A toy store sells accessories to go with the latest action figure. The store projects that it will sell a certain number of accessories for every box of a dozen action figures it orders. Let d represent one box of a dozen action figures. A new accessory, the Laser Saber, has sales equal to 1.5 times the difference of the number of Invisible Shields and X-Ray Vision Glasses.Part AWrite an expression to represent the number of Laser Sabers sold.Part BHow would you write an equivalent expression for the price in simplified form? Explain.Part CAdd the expressions to find the total number of all four accessories sold.Part DIf the toy store sold 78 of the latest action figure, how many accessories did it sell? Explain.
Answers
Answer:
a) 12d + 9
c) 30d + 12
d) 207
Explanation:
First, we need to write an expression for each accessory.
Since d is the number of boxes, we get:
Turbo Jet Pack. Six times the number of boxes plus seven
6d + 7
X-Ray Vision Glasses. Five less than two times the number of boxes
2d - 5
Invisible Shield. One more than ten times the number of boxes
10d + 1
Part A.
Then, the Laser Saber has sales equal to 1.5 times the difference of the number of Invisible Shields and X-Ray Vision Glasses.
1.5((10d + 1) - (2d - 5))
Because 10d + 1 is the number of invisible shields and 2d - 5 is the number of X-Ray Vision Glasses.
Now, we can simplify the expression as
1.5(10d + 1 - 2d + 5)
1.5(8d + 6)
1.5(8d) + 1.5(6)
12d + 9
Part C.
Then, we need to add all the expressions before to get:
(6d + 7) + (2d - 5) + (10d + 1) + (12d + 9)
(6d + 2d + 10d + 12d) + (7 - 5 + 1 + 9)
30d + 12
Therefore, the total number of all four accessories is 30d + 12
Part D.
To know how many accessories did it sell, first, we need to find how many dozens are 78 action figures, so
78/12 = 6.5
Therefore, they sold 6.5 boxes of the action figure. Now we can find the number of accessories sold, replacing d with 6.5 in the expression of part C, so
30d + 12
30(6.5) + 12
195 + 12
207
Then, they sold 207 accessories.

Therefore, integrate the norm of the curve's tangent vector over a specified interval. An example curve could be y = x^2, with the arc length calculated by integrating the square root of 1 + (2x)^2 over a given interval.
A line integral can determine the arc length of a curve c by integrating the norm of the curve's tangent vector over a specified interval. The formula for arc length is given by the integral of the middle of the curve's derivative with respect to its parameter. This involves taking the square root of the sum of the squares of the components of the derivative and integrating this result over the interval of interest. An example of a curve that is not part of a circle could be the curve defined by the equation y = x^2. To calculate its arc length, we would first need to find its derivative, which is y' = 2x. Then, we would integrate the square root of 1 + (2x)^2 over the interval of interest, such as from x = 0 to x = 2.
Therefore, integrate the norm of the curve's tangent vector over a specified interval. An example curve could be y = x^2, with the arc length calculated by integrating the square root of 1 + (2x)^2 over a given interval.
