My cookbook says that a salad sauce should be made of 1/3 lemon juice and 2/3 oil.I put in 50 ml oil but my hand slipped when adding the lemon juice and the total volume is now 90 ml.
How much oil must I add to have the correct proportions?

A 10 ml B 30 ml C 40 ml D 80 ml

Answers

Answer:

We know that you put (90-50), or 40 ml of lemon juice. If 40 ml of lemon juice is 1/3 of the total sauce, then 80 ml of it should be oil.

So you should add 30 ml more oil to make it proportional.

A carton of paper is priced at $27.00 now. If the papergoes on sale for 25% off the current price, what will be the sale price of the carton?

Answers

If a pack of paper costs $27.00 right now. If the paper is discounted by 25% from its regular price, the carton will be sold for $6.75.

What is the percentage?

It's the ratio of two integers stated as a fraction of a hundred parts. It is a metric for comparing two sets of data, and it is expressed as a percentage using the percent symbol.

Given that a carton of paper costs $27.00 right now, If the price of the paper is discounted by 25%,

The usage of percentages is widespread and diverse. For instance, numerous data in the media, bank interest rates, retail discounts, and inflation rates are all reported as percentages. For comprehending the financial elements of daily life, percentages are crucial.

The sale price of the carton is,

sale price = 25% of the current price

sale price =(25/100)× $27.00

sale price = $6.75

Thus, if a pack of paper costs $27.00 right now. If the paper is discounted by 25% from its regular price, the carton will be sold for $6.75.

Divide the 27 by 4 and that will give you 6.75. Subract the 6.75 from the 27 and theres your answer (20.25) so the sale price is $20.25

How do I solve this?

Answers

Answer:

Step-by-step explanation:

To find the values of a and b, we can use the given information and apply the properties of rectangles and parallel lines.

First, let's calculate the area of the rectangle PQRS. We are given that the area is 84 cm², and since PQRS is a rectangle, its area is equal to the product of its length and width. Therefore, we can set up the equation:

Length × Width = 84

Next, we know that XY is parallel to PS. This means that the length of XY is equal to the length of PS. Since the length of PS is a + b cm, we can write:

Length of XY = a + b

Now, we are given that the area of PXYS is 21 cm². Using the same logic, the area of PXYS is equal to the product of its length and width, so we can set up another equation:

Length of XY × Width of XY = 21

Since the width of XY is 9 cm (given as RY), we can substitute the values into the equation:

(a + b) × 9 = 21

Simplifying this equation, we get:

9a + 9b = 21

Now, we have two equations:

1) Length × Width = 84

2) 9a + 9b = 21

To solve these equations simultaneously, we need to rearrange equation 1) to solve for either length or width. Let's solve for length:

Length = 84 / Width

Substituting in the value of width from equation 2), we get:

Length = 84 / (9a + 9b)

Now, we can substitute this expression for length into equation 2):

(84 / (9a + 9b)) × (9) + 9b = 21

Simplifying this equation, we get:

84 + 9b = 21(9a + 9b)

Expanding, we get:

84 + 9b = 189a + 189b

Combining like terms, we get:

-180b = 189a - 84

Dividing by -180, we get:

b = (189a - 84) / -180

We have found the expression for b in terms of a.

To find the value of a, we can substitute this expression for b into equation 2):

9a + 9((189a - 84) / -180) = 21

Simplifying this equation will give us the value of a.

Please note that without specific numerical values or additional constraints, it is not possible to determine the exact values of a and b. However, by solving the equations as shown above, we can express the values of a and b in terms of each other.

What is the measurement of STU?

Answers

Triangles UTR and RTS are congruent, because they're both right triangles, RS=RU and side TR is in common.

This implies that angles RTS and RTU are congruent, and thus we have

5w-69=w+3 \iff 4w=72 \iff w=(72)/(4)=18

Finally, angle STU is the sum of RTS and RTU, which is the same as 2RTU, since they have the same measure. So, we have

RTS+RTU=2RTU=2(w+3)=2w+6

and since w=18, we have

2w+6=2\cdot 18+6=36+6=42

marsha wants to determine the vertex of the quadratic function f(x) = x2 – x 2. what is the function’s vertex? (1, 1) (1, 3) (1/2,3/2 (1/2,7/4)

Answers

f(x) = x^2 - x + 2
f(x) = x^2 - x + 1/4 + 2 - 1/4
f(x) = (x - 1/2)^2 + 7/4
Therefore, vertex = (1/2, 7/4)

So A would be your answer
