Step-by-step explanation:

I assume the fraction 3/5 is raised to the 3rd power.

I assume this is the given expression.

[tex] (\dfrac{3}{5})^3 [/tex]

The base is 3/5    True

The base is 3     False

The exponent is 3    True

The expanded form is [tex] \dfrac{3}{5} \times \dfrac{3}{5} \times \dfrac{3}{5} [/tex]       True

The expanded form is [tex] \dfrac{3 \times 3 \times 3}{5} [/tex]     False

[tex] (\dfrac{3}{5})^3 = \dfrac{9}{15} [/tex]      False

[tex] (\dfrac{3}{5})^3 = \dfrac{27}{125} [/tex]      True

Answer:

Answer:

3

Step-by-step explanation:

The missing number in the sequence is 52.

In order to determine the missing number, the pattern in the sequence has to be determined.

The difference between the second and first number is 144 - 127 = 17

The third number is 3 times smaller than the second number: 144 / 48 = 3

The difference between the fourth number and the third number is 66 - 48 = 18.

The fifth number is 2 times smaller than the fourth number: 66/33 = 2

Based on this sequence, the sixth number would be 19 more than the fifth number. 33 + 19 = 52

Answer: B) The coordinate of L is (3,-2).

Step-by-step explanation:

Given that L is the midpoint of JK, we can apply the following equation to obtain the coordinates of point L:

L=(5+1/2, 3-7/2)

As a result of resolving this, we obtain

L=(6/2, -4/2)

L=(3,-2)

Therefore the answer is (3,-2)

Answer:

130 cents, or $1.30.

Step-by-step explanation:

To find the total cost of the meal, add the costs of each product.

Since the cost of the sandwich was 80 cents, the cost of the milk was 20 cents and the cost of the pie was 30 cents, then the total cost of the meal (in cents) is:

[tex]80+20+30[/tex]

Add the numbers from left to right. Since 80+20 is equal to 100, then:

[tex]80+20+30=100+30[/tex]

Finally, notice that 100+30 is equal to 130:

[tex]100+30=130[/tex]

So, the total cost of the meal was 130 cents. Each 100 cents is equal to 1 dollar. Then, 130 cents is the same as $1.30.

Therefore, the cost of the meal was 130 cents, or $1.30.

Step-by-step explanation:

Acceleration is the rate of change of velocity over time

His final velocity is 14.4 meters per second

From the question, we have:

Using the first equation of motion, we have:

[tex]v = u + at[/tex]

So, the equation becomes

[tex]v = 0 + 1.8 * 8[/tex]

[tex]v =14.4[/tex]

Hence, the final velocity is 14.4 meters per second

Answer:

The dimension of the room is Length of 5m and Width of 8m

Step-by-step explanation:

Formula for perimeter of a rectangle is;

P = 2(L + W)

Where;

L is length

W is width

We are given;

Width; W = 1.6L

Perimeter; P = 26 m

Thus;

2(1.6L + L) = 26

2(2.6L) = 26

5.2L = 26

L = 26/5.2

L = 5 m

W = 1.6 * 5

W = 8 m

Answer: 81/8 kg

Using statistical concepts, it is found that the variance for this data set is of 22 oz squared.

From the second bullet point, the variance can also be interpreted as the sum of squared deviations divided by the sample size.

In this problem, the sum of squared deviations is 220 and the sample size is 10, hence, the variance for this data set is of 22 oz squared.

Answer:

Area is  220 cm²

Step-by-step explanation:

Firstly divide the polygon into  rectangle and triangle

For rectangle  area

 Area = A  =  L × W = 11 × 18 = 198 cm²

For triangle

Area =  A =  1/2 bh = 1/2 × (15-11) × (18-7) = 1/2 × 4 ×11 = 44/2 = 22 cm²

Add them

     198 + 22 = 220cm²
