a birthday cake at the bakery was $30 originally. During a sale, a discount of 28% was given. A further 15% discount was given to those customers who ordered a month earlier. How much would a customer who orders a month earlier need to pay for the birthday cake during the sale?
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.

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:
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

A cereal company is putting 1 11 of 4 44 prizes in each box of cereal. The prizes are evenly distributed so the probability of winning any given prize is always 1 / 4 1/41, slash, 4.
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
Uma piscina possui 5 m de comprimento, 3 m de largura e 2,5 m de profundidade. Calcule: a) A quantidade de azulejo necessária para forrar a piscina b) A quantidade de água que cabe nessa piscina. c) seu volume em m3
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
there are 25 gold paper clips and 75 silver paper clips in each box. How many silver paper clips are in 8 boxes. (THIS IS MULTIPLICATION)
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
f(x) = 2x^2 – 7x – 6
Find f(6)
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

A train traveled at a speed of 60 miles per hour for 5 hours. How far did the train travel?
O 12 miles
O 30 miles
O 120 miles
O 300 miles
Answer:
d
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

at a sale this week, a desk is being sold for $589. This is a 38% discount from the original price. What is the original price? WILL GIVE BRAINLIEST IF CORRECT! ( you have to have an 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.
What is a percentage?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:
42% decrease
Step-by-step explanation:
To get the percent increase or decrease, subtract 450 by 261 to get 189. Then divide this by 450 to get 0.42. Multiply this by 100 to get a 42 percent decrease.
