Step-by-step explanation:
in two months
Decrease of 25%
so you need to do
25%*12 is 3 minutes
Find the difference from 12 minutes
12-3 is 9 minutes.
therefore, his mile time is 9 minutes in two months
After improving his running speed by 25%, Guy would now run a mile time 9 minutes.
It would take for Guy to run a mile after improving his running speed by 25%. Guy's original mile time was 12 minutes. To find his new mile time, we calculate 25% of 12 minutes, which is 3 minutes.
Then, we subtract that from the original 12 minutes: 12 minutes - 3 minutes = 9 minutes. Therefore, Guy's new mile time, after reducing it by 25%, is 9 minutes.
Cual es el volumen en metros cúbicos y en litros de 300 N de aceite de oliva cuyo peso especifico es de 9016 N/ m3
SPANISH
Como el peso específico del objeto es Y = 9016 N / m ^ 3, puede ver que será Y = 300 N / V m ^ 3
V (m ^ 3) = 300 N / (9016 N / m ^ 3)
V (m ^ 3) = 0, =. 033 m ^ 3
1 Litro es 0,001 m ^ 3
(.033 m ^ 3) * (1 L / 0,001 m ^ 3) = 35,937 L
ENGLISH
Since the specific weight of the object is Y = 9016 N/ m^3 you can see that it will be Y = 300 N / V m^3
V(m^3) = 300 N / (9016 N/m^3)
V(m^3) = 0,=.033 m^3
1 Litro es 0,001 m^3
(.033 m^3) * (1 L / 0,001 m^3) = 35,937 L

The specific weight is the weight of the per unit volume of a material. The volume of the olive oil is 34 L.
What is specific weight?The specific weight is the weight of the per unit volume of a material. It is given by the formula,
[tex]\rm Specific\ Weight, \gamma= Density \times g = \dfrac{Weight}{Volume}[/tex]
As the weight of the oil is given and the specific density is also given, therefore, we can find volume as,
[tex]\rm \gamma = \dfrac{Weight}{Volume}\\\\\rm 9016= \dfrac{300}{Volume}\\\\Volume = \dfrac{300}{9016}\\\\Volume = 0.0333\ m^3[/tex]
Now, we know that 1 m³ = 1000 litres, therefore,
[tex]\rm Volume = 0.034\ m^3\\\\Volume = (0.034 \times 1000)\ liters\\\\Volume = 34\ liters[/tex]
Hence, the volume of the olive oil is 34 L.

Pyramids A and B are similar. Pyramid A has a height of 8 in., and Pyramid B has a height of 24 in. Pyramid A has a volume of 384 in3. What is the volume of pyramid B?
Answer:142
Step-by-step explanation:no
The volume of Pyramid B can be calculated by using the ratio of the heights of the similar pyramids, cubed. As the height of Pyramid B is 3 times the height of Pyramid A, its volume is 27 times greater. Thus, Pyramid B has a volume of 10368 cubic inches.
Explanation:
Calculating the Volume of Similar Pyramids
To solve this problem, we can use the properties of similar figures. When two pyramids are similar, the ratio of their volumes is equal to the cube of the ratio of their corresponding linear dimensions. In this case, Pyramid A has a height of 8 inches and a volume of 384 cubic inches. Pyramid B is similar to Pyramid A but has a height of 24 inches, which is 3 times the height of Pyramid A (since 24 in. / 8 in. = 3).
Since the pyramids are similar, the ratio of their volumes will be the cube of the ratio of their heights (in this case, 33 or 27). Therefore, the volume of Pyramid B will be 27 times greater than the volume of Pyramid A.
To find the volume of Pyramid B, we simply multiply the volume of Pyramid A by this ratio:
Volume of Pyramid B = Volume of Pyramid A × (ratio of heights)3Volume of Pyramid B = 384 [tex]in^3[/tex] × 27Volume of Pyramid B = 10368 [tex]in^3[/tex]Thus, the volume of Pyramid B is 10368 cubic inches.
Trina's car uses 12 gallons of gas to travel 144 miles. If she has 6 gallons of gas in the tank, how much more gas will she need to drive 240 miles?
Answer: 14gallons
Step-by-step explanation:
12gallons/144miles = 1gallon/12miles
Therefore 6gallons = 12*6 = 72miles.

Answer:
3 + 2.50m = c
Step-by-step explanation:
Since you don't know how many miles you are traveling in the taxi, you can use the variable m to represent miles. 3 is the original fee. So, 3 + 2.50m = c is your answer.
Sue bought 3.5 yards of material at $8.70 per
yard and 5 yards of lace trim. She spent $32.90 in
total. Calculate the cost of 1 yard of lace trim.
Answer: $.49
step explanation:
Sue bought 3.5 yards of material at $8.70 per yard (3.5x8.70=30.45)
Sue also bought 5 yards of lace trim.
Her total was 32.90 and we want to find out how much the lace trim cost.
We will subtract the initial material to get the subtotal cost for just the lace trim. (32.90-30.45=2.45)
5 yards of lace trim total up to $2.45. To get how much each yard cost we will divide (2.45÷5=.49)
Each yard of lace trim costs $.49 cents
Kendra lives 10 Km from the northern tip of swan lake and 6 Km from the southern tip of swan lake. What is the north - south distance across swan lake?
Answer:
The north - south distance across swan lake is 8 km
Step-by-step explanation:
Look to the attached figure
Kendra's house and the distances between it and the North tip, southern tip of swan lake formed a right Δ
∵ Kendra lives 10 Km from the northern tip of swan lake
- That means the length of the hypotenuse of the right Δ is 10
∴ The hypotenuse of the right Δ = 10
∵ Kendra lives 6 Km from the southern tip of swan lake
- That means the length of the horizontal leg of the right Δ is 6
∴ The horizontal leg = 6
- By using Pythagoras Theorem
∵ (hypotenuse)² = (H.leg)² + (V.leg)²
∴ (10)² = (6)² + (x)²
∴ 100 = 36 + x²
- Subtract 36 from both sides
∴ 64 = x²
- Take √ for both sides
∴ 8 = x
∴ The vertical leg of the right triangle = 8
∵ x represents the north-south distance across swan lake
∴ The north - south distance across swan lake is 8 km

If Abby rolls two number cubes a hundred times, about how many times would she expect a product greater than 10.
Answer:
20 times ??
Step-by-step explanation:
Abby would expect to roll a product greater than 10 about 42 times in 100 rolls of two number cubes.
To determine how many times Abby would expect to roll a product greater than 10 when rolling two number cubes (dice) a hundred times, we can use probability.
Each number cube has six sides, numbered 1 through 6. When two dice are rolled, the possible products range from 1 (1*1) to 36 (6*6).
To find the probability of getting a product greater than 10, we can list out the combinations that result in products greater than 10:
(2, 6), (3, 5), (3, 6), (4, 4), (4, 5), (4, 6), (5, 3), (5, 4), (5, 5), (5, 6), (6, 2), (6, 3), (6, 4), (6, 5), (6, 6)
That's a total of 15 combinations out of 36 possible combinations.
So, the probability of rolling a product greater than 10 is [tex]\( \frac{15}{36} \).[/tex]
To find out how many times Abby would expect this to happen in 100 rolls, we multiply the probability by the number of trials:
[tex]\[ \text{Expected occurrences} = \text{Probability} \times \text{Number of trials} \][/tex]
[tex]\[ \text{Expected occurrences} = \frac{15}{36} \times 100 \][/tex]
[tex]\[ \text{Expected occurrences} \approx \frac{5}{12} \times 100 \][/tex]
[tex]\[ \text{Expected occurrences} \approx 41.67 \][/tex]
So, Abby would expect to roll a product greater than 10 approximately 42 times in 100 rolls.
Jen's garden is 4 feet wide and gas ab area of 28 square feet. What is the length of Jne's garden? how do you know
Answer:
The Length is 7
Step-by-step explanation:
If Jen has a garden with a total area of 28 square feet and it is 4 feet wide to find the length you will divide the total area with the width. This should give you the length of the Garden which is 7. To double check your answer you can multiply the width with the length to get the total area of 28 square feet.
The length of Jen's garden is 7 feet, calculated by dividing the area of 28 square feet by the width of 4 feet.
Explanation:To find the length of Jen's garden, we need to use the information about the garden's area and width. The area of a rectangle (which is the shape we can assume the garden is) is calculated by multiplying the length by the width. Given that Jen's garden has an area of 28 square feet and a width of 4 feet, we can set up the following equation:
Area = Length × Width
28 square feet = Length × 4 feet
To solve for the length, divide both sides of the equation by 4 feet:
Length = 28 square feet / 4 feet
Length = 7 feet
Therefore, the length of Jen's garden is 7 feet. This is how we determine the dimensions of a garden plot by using multiples of length and width. To actually measure the garden, one would use a measuring tape.
