We conclude that:

Step-by-step explanation:

Given the expression

[tex]\left(5p^3\right)\:\left(-1m^8p^2\right)[/tex]

Apply the rule:

[tex]a\left(-b\right)=-ab[/tex]

so the expression becomes

[tex]\left(5p^3\right)\left(-1\cdot \:m^8p^2\right)=-5p^3\cdot \:1\cdot \:m^8p^2[/tex]

Apply the rule:

[tex]a^b\cdot \:a^c=a^{b+c}[/tex]

so the expression becomes

                             [tex]=-5p^{3+2}\cdot \:1\cdot \:m^8[/tex]         ∵ [tex]p^3p^2=p^{3+2}[/tex]

                             [tex]=-5p^5\cdot \:1\cdot \:m^8[/tex]

                             [tex]=-5p^5m^8[/tex]

Answer:

3 1/4

Step-by-step explanation:

Laura walked 6 1/2 laps of a circular path in 2 hours. At that rate, she walk circular path in one hour is, 3 1/4 laps.

Rate is a ratio of change in one quantity w.r.t. change in another quantity.  The net change in one quantity  is written as, Δy and the net change in another quantity is written as, Δx.

So formula for the rate is,

m = change in one quantity/change in another quantity = Δy/Δx

Given that,

Laura walked 6 1/2 laps of a circular path in 2 hours,

Suppose, she walked at constant speed

So, we can say that

Whatever, distance she walked in 2 hour that will be double of the distance she walked in 1 hour,

Therefore, laps of the path she did  walk in one hour is (13/2)/2 =13/4

Hence, laps she walked is 3 1/4

Answer: Mom bought 10 chickens

Step-by-step explanation: if each chicken had 2 wings and there were 20 wings you divide

Answer:

3. Zack has 6 times more seeds than Ben, if Ben has 5 seeds, just multiply how many seeds Ben has by 6, which means Zack planted 30 seeds (This can be written Z=B*6, where Z is how many seeds Zack has, and B is how many seeds Ben has)

1.  If there are a total of 40 cards divided into 8 groups of students, that means that each group got 5 card (40 ÷ 8 = 5)

2. If each chicken has 2 wings, and she has a total of 20 wings, that means that she bought a total of 10 chickens (20 ÷ 2 = 10)

Answer:

  7 1/8 yd

Step-by-step explanation:

The perimeter is the sum of the three side lengths. They are all the same, so we can use multiplication to find their sum.

  P = 3·(2 3/8 yd) = 6 9/8 yd  . . . . .  9/8 = 1 1/8

  P = 7 1/8 yd

The perimeter is 7 1/8 yards.

Answer:

[tex]perimeter \: of \: the \: triangle \\ = 2 \frac{3}{8} +2\frac{3}{8} + 2 \frac{3}{8} \\ = 3 \times 2 \frac{3}{8}\\= 3 \times \frac{19}{8} \\ = \frac{57}{8} \: yd \\ = 7 \frac{1}{8} \: yd[/tex]

Answer:

45 strawberry muffins

Step-by-step explanation:

In order to solve this equation you are going to have to multiply 150 by 1/5 bananas and 1/2 blueberry in order to get how much strawberry muffins were made. So first we are going to convert 1/5 and 1/2 into decimals:

1/5 = 0.2

1/2 = 0.5

Now we are going to multiply 0.2 and 0.5 by 150 in order to figure out how much banana and Blueberry muffins were made:

0.2 * 150 = 30

0.5 * 150 = 75

So 30 banana muffins were made and 75 blueberry muffins were made, now that we know this we are going to add 30 and 75 together and subtract the answer from 150. THe reason we are subtracting 75 + 30 from 150 is because we are trying to segregate the strawberry muffins from the total number:

75 + 30 = 105

now we subtract:

150 - 105 = 45

So the number of strawberry muffins made was 45.

I hope this helps.

Answer:

The total number of strawberry muffins are: 45

Step-by-step explanation:

Total baked muffins = 150

1/5 of the muffins are banana, so

Banana muffins = 1/5 × 150

                          = 30

1/2 of the muffins are blueberry, so

Blueberry muffins = 1/2 × 150

                              = 75

The rest are strawberry, so

Strawberry muffins = Total muffins - Banana muffins - Blueberry muffins

                                 = 150 - 30 - 75

                                  = 45

Therefore, the total number of strawberry muffins are: 45

Answer:

r = 1.68 ft

Step-by-step explanation:

Volume of a sphere, V = 4/3πr³

V = 20 ft³

π = 3.14

r = ?

V = 4/3πr³

20 = 4/3 × 3.14 × r³

20 = (4×3.14×r³)/3

Cross product

20 × 3 = 4 × 3.14 × r³

60 = 12.56r³

r³ = 60/12.56

= 4.7771

r = 3√4.7771

= 1.6842

Approximately

r = 1.68 ft to the nearest hundredth

Answer:

2 block east from home

Step-by-step explanation:

Given an expression for how many blocks east Robert is from his home after finding his wallet as the sum 7+​(−​5),

Simplifying the given expression

7+(-5) = 7-5 (note that the product of a plus and minus sign will give a minus sign)

7-5 = 2

Hence Robert will be 2 block east from home

Answer:

93 Sq.ft

Step-by-step explanation:

Formula for total surface area of a cylinder is;

TSA = 2πr² + 2πrh

In the question, we have Half cylinder, thus; TSA for half cylinder is;

TSA_½ = (2πr² + 2πrh)/2

TSA_½ = πr² + πrh

r = 3/2 = 1.5 ft

h = 5 ft

Thus;

TSA_½ = π(1.5)² + π(1.5 × 5)

TSA_½ = 30.63 Sq.ft

Surface area of rectangular prism is;

SA = 2(lw + lh + wh)

We have;

l = 5 ft

h = 2 ft

w = 3 ft

Thus;

SA = 2((5 × 3) + (5 × 2) + (2 × 3))

SA = 2(15 + 10 + 6)

SA = 62 Sq.ft

Thus, surface area of treasury is;

S.A_t = TSA_½ + SA

S.A_t = 30.63 + 62

S.A_t = 92.63 approximately 93 Sq.ft

Hence, ption B is true.

Step-by-step explanation:

Given the expression

[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}[/tex]

solving the expression

[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}[/tex]

as

[tex]\sqrt{x^2y^3}=xy\sqrt{y}[/tex]

[tex]2\sqrt{x^3y^4}=2xy^2\sqrt{x}[/tex]

so the expression becomes

[tex]\:\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=xy\sqrt{y}+2xy^2\sqrt{x}+xy\sqrt{y}[/tex]

Group like terms

                                        [tex]=2xy^2\sqrt{x}+xy\sqrt{y}+xy\sqrt{y}[/tex]

Add similar elements

                                        [tex]=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]

Therefore, we conclude that:

[tex]\sqrt{x^2y^3}+2\sqrt{x^3y^4}+xy\sqrt{y}=2xy^2\sqrt{x}+2xy\sqrt{y}[/tex]

Hence, option B is true.
