(just the first question) pls help my work is due tonight i will give brainliest

Answer:

2nd and 4th options are correct

Step-by-step explanation:

Here, let’s work with the number of tablespoon of lemon juice

From the question ;

2 servings = 1/2 tea spoon

So 4 servings = 2 * 1/2 = 1 tea spoon

Let us convert this to table spoon

3 teaspoon = 1 table spoon

1 teaspoon = x table spoon

3 * x = 1

x = 1/3 tablespoon

As we can see, this is not any part of the options

Let us check for 6 servings

6 servings = 3 * 1/2 = 1.5 tea spoon

From the question;

3 tsp = 1 tbsp

1.5 tsp = x tbsp

x * 3 = 1.5

x = 1.5/3

x = 1/2 tbsp

As we can see, second option is correct

second part

we are working with vinegar

For 2 servings = 2 tbsp of vinegar

4 servings = 2 * 2 = 4 tbsp of vinegar

From the question

2 tbsp = 1/8 cup

4 tbsp = x cup

x = (4 * 1/8)/2 = 1/2/2 = 1/4 cup

For 6 servings

= 3 * 2 = 6 tbsp

From the question;

2 tbsp = 1/8 cup

6 tbsp = x cup

2 * x = 6 * 1/8

x = 6 * 1/8 * 1/2

x = 3/8 cups of vinegar

So therefore, options 4 and 2 are correct

Answer:

0.75

Step-by-step explanation:

The complete question is attached below.

The dots on the numbers of the dot plot represent the number of boxes it took Vera to get all the prizes.

Therefore, the probability of getting all the prizes in 9 or fewer boxes is the sum of the number of times it took her to get 4 prizes in 9 boxes or fewer.

Hence:

P(x ≤ 9) = P(x = 4) + P(x = 5) + P(x = 6) + P(x = 7) + P(x = 8) + P(x =9)

P(x ≤ 9) = (4 / 36) + (6 / 36) + (3 / 36) + (4 / 36) + (4 / 36) + (6 / 36)

P(x ≤ 9) = 27 / 36

P(x ≤ 9) = 3 / 4 = 0.75

Answer:

600

Step-by-step explanation:

75 x 8 = 600

Answer:

the answer is 600 silver paper clips

Step-by-step explanation:

So the question asks how many SILVER PAPER CLIPS are in 8 boxes. The questions adds 25 GOLD CLIPS just to throw you off. You do not do nothing with it, it just there to mess with your mind. Also it says 75 silver clips in EACH box and there are 8 boxes. So you multiply 75 with 8 and get 600 SILVER PAPER CLIPS

Answer:

The correct answer is d.

Step-by-step explanation:

Let's solve each answer and see which one matches.

Note that in each case, you simply add or subtract from x inside the radical to move left or right respectively.  Similarly, just add or subtract to the full expression to move up or down respectively. Doing so we get:

a) [tex]f(x) = \sqrt[3]{x + 7} + 3[/tex]

b)[tex]f(x) = \sqrt[3]{x - 3} - 7[/tex]

c)[tex]f(x) = \sqrt[3]{x - 3} + 7[/tex]

d)[tex]f(x) = \sqrt[3]{x - 7} + 3[/tex]

So d is the correct answer.

Answer:

a) 70 azulejos

b) 37500 litros

c) 37.5m³

Step-by-step explanation:

A piscina tem 5 m de comprimento, 3 m de largura e 2,5 m de profundidade.

Comprimento = 5m

Largura = 3m

Profundidade (altura) = 2,5 m

Calcular:

a) A quantidade de ladrilhos necessária para cobrir a piscina

Isso é calculado como a área de superfície da votação

A = 2 (wl + hl + hw)

A = 2 × (3 × 5 + 2.5 × 5 +2.5 × 3)

A = 70 m²

Observe que:

1 m² = 1 azulejo

70 m² = 70 azulejos

b) A quantidade de água que pode caber na piscina.

1 m³ = 1000 litres

O volume de uma piscina = Comprimento × Largura × Altura

= 5m × 3m × 2.5m

= 37.5m³

1 m³ = 1000 litros

37.5m³ =

37.5 × 1000 litros

= 37500 litros

c) seu volume em m³

O volume de uma piscina = Comprimento × Largura × Altura

= 5m × 3m × 2.5m

= 37.5m³

Step-by-step explanation:

The train traveled for a distance of 300 miles

What is Speed?

Speed is defined as the rate of change of position of an object in any direction. Speed is measured as the ratio of distance to the time in which the distance was covered. Speed is a scalar quantity as it has only direction and no magnitude

Speed = Distance / Time

Given data ,

Let the speed of the train be S = 60 miles per hour

The time taken by the train to reach the destination = 5 hours

So ,

The distance traveled by the train = Speed of the train x Time taken

                                                         = 60 x 5

                                                         = 300 miles

Therefore , the distance traveled by the train is 300 miles

Hence , The train traveled for a distance of 300 miles

Answer:

f(6)=24

Step-by-step explanation:

[tex]f(x) = 2x^2 - 7x - 6\\f(6) = 2(6)^2 - 7(6) - 6=2*36-42-6=24[/tex]

Answer:

f(6) = 24

Step-by-step explanation:

f(x) = 2x² – 7x – 6: f(6)

f(6) = 2(6)² - 7(6) - 6

= 2 × 36 - 42 - 6

= 72 - 48

f(6) = 24

Thus, f(6) = 24

Step-by-step explanation:

Answer: 950

Step-by-step explanation: x= original price

so we know that the desk cost x dollars and after 38% discount the desk was 589

589= discounted price= original price x-the 38%

589=x-0.38x=0.62 x

x=589/0.62=950

The original price of the desk is $950.

The percentage is calculated by dividing the required value by the total value and multiplying by 100.

Example:

Required percentage value = a

total value = b

Percentage = a/b x 100

Example:

50% = 50/100 = 1/2

25% = 25/100 = 1/4

20% = 20/100 = 1/5

10% = 10/100 = 1/10

We have,

The original price = 100%

Selling price = $589

Discount = 38%

100% - 38% = 589

62% = $589

Multiply 100/62 on both sides.

100% = 100/62 x 589

100% = $950

Thus,

The original price of the desk is $950.

Answer:

$18.36

Step-by-step explanation:

In this question, we have to find the cost of the cake for the customer who orders a month early.

We know that the original price of the cake is $30.

We also know that there was a 28% discount and a 15% discount added to the purchase.

Remember, You don't add discount percentages together, you discount the prices separately.

Solve:

First, apply the 28% discount.

30 · 0.28 = 8.40

30 - 8.40 = 21.60

Now apply the 15% discount to the new price.

21.60 · 0.15 = 3.24

21.60 - 3.24 = $18.36

They needed to pay $18.36 for the cake.
