Answer:

[tex]0.5(4x + 6) = 5x + 24.7 \\ 2x + 3 = 5x + 24.7 \\ 3 - 24.7 = 5x - 2x \\ - 21.7 = 3x \\ \frac{ - 21.7}{3} = \frac{3x}{3 } \\ x = - 7.2333[/tex]

Answer:

x=-37.4

Step-by-step explanation:

0.5(4x + 6) = 5x + 24.7          (0.5*4x=4.5x)

4.5x+6=5x+24.7

4.5x-5x+6=5x-5x+24.7

-0.5x+6=24.7

-0.5x+6-6=24.7-6

-0.5x=18.7

-0.5x/-0.5=18.7/-0.5

x=-37.4

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.

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.

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

Answer: The distance between the points is 2 and 1/2 units.

Step-by-step explanation:

We want to calculate the distance between the points:

First, to calculate the difference between the vectors (a,b) and (c,d) we have:

(a, b) - (c, d) = (a -c, b - d)

(-2 + 1/2, -3) and (1, - 3)

First, we calculate the difference of the two ponts:

(-2 + 1/2, -3) - (1, - 3) = (-2 + 1/2 - 1. -3 - (-3)) = (-3 + 1/2, 0 )

now this is the distance vector, we can calculate the magnitude of the distance by calculating the magnitude of this vector, this is:

d = √((-3 +1/2)^2 + 0^2) = √(-3 + 1/2)^2 = (3 - 1/2) = 2 + 1/2

Answer:

(sum of terms) / (number of terms)

the numbers in the data set are :

3,3,3,4,6,6,7,8

they are already arranged in order, so no need to rearrange.

add the numbers together to find the total :

3 +3 +3 +4 +6+ 6+7 +8

= 40

ALSO,

find how many number of terms they are --- this is 8

Last

use the mean formula to solve :

(sum of terms) / (number of terms)

= 40/8

= 5

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:

Thus, the volume of Pyramid B is 10368 cubic inches.

Answer:

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.

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.

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.

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
