Answer:

22- b

23- d

24- b

Step-by-step explanation:

22- perimeter =2(length + width)=2(40+20)=120

23- width =100m

length = 3×width =3×100=300

perimeter =2(300 +100)= 800

24= hanz perimeter = 40m

Arthur's perimeter =42m

hence Arthur needs more fence

The amount by Cesar’s minimum monthly payment increase will be $91.44.

Cesar only has 12 months left before he pays off his credit card completely.

His current balance = $3,750

                       APR = 17.5%

Now we use the formula :

[tex]\rm Present \ value \ of \ anuity= P=( 1-\frac{1+r}{r} })^{-n}[/tex]

PV = Present Value

P   = Periodic payment

r    = rate per period

n   = number of period

Now for the first case:

PV of annuity = $3,750

P =?

r = 17.5% annually = % monthly  monthly

n = 12 months

Now we put the values in the formula

[tex]3750=P(1-\dfrac{(1+\dfrac{17.5}{1200})^{-12}}{\dfrac{17.5}{1200} } )[/tex]

[tex]P=\dfrac{3750}{\dfrac{1-0.8405}{0.01458} }[/tex]

[tex]P=342.91[/tex]

Now for the second Case :

PV of annuity = 3750 + 1000 = 4750

P =?

r = 17.5% annually = % monthly =  monthly

n = 12 months

Putting the values in the formula

[tex]4750=P(1-\dfrac{(1+\dfrac{17.5}{1200})^{-12}}{\dfrac{17.5}{1200} } )[/tex]

[tex]P=\dfrac{4750}{1-\dfrac{1+\frac{17.5}{1200} }{\frac{17.5}{1200} } }[/tex]

[tex]P=\dfrac{4750}{\dfrac{0.1595}{0.01458} } =434.35[/tex]

Cesar's increased monthly payment will be

434.35 - 342.91 = 91.44

Hence, the amount by Cesar’s minimum monthly payment increase will be $91.44.

The correct expression is 5[tex]z^{4}[/tex] + 29 + 8[tex]y^{3}[/tex]

distributive law, in mathematics, the law relating the operations of multiplication and addition, stated symbolically, a(b + c) = ab + ac; that is, the monomial factor a is distributed, or separately applied, to each term of the binomial factor b + c, resulting in the product ab + ac.

according to the question

Apply multiplicative distribution law

5[tex]z^{4}[/tex] - 3 + 8[tex]y^{3}[/tex] + 32

Combine like terms

Step-by-step explanation:

The number of lemonade should Justin give to each person is 7 with one lemonade still left.

It is given that Justin has 64 ounces of lemonade to divide among 9 people.

We have to find out that how much lemonade should he give to each person.

What will be the value of each part , if 120 is divided in 6 equal parts ?

The value of each part will be 120 divided by 6 or 120 ÷ 6 or 20 i.e., 120 is divided into 6 equal parts of 20 each.

As per the question ,

No. of ounces of lemonade to divide among 9 people = 64

No. of lemonade each people will get = 64 ÷ 9

or

64 ÷ 9 = 7.1111

So , we can't equally divide it because if 7 each is divided between 9 people , one lemonade will still be left.

i.e.,

7 × 9 = 63

64 - 63 = 1

1 still left

Thus , the number of lemonade should Justin give to each person is 7 with one lemonade still left.

Answer:

  11.78 in³

Step-by-step explanation:

The formula for the volume of a cone is ...

  V = 1/3(πr²h)

The cone's radius is half its diameter, so is 1.5 inches. The volume is ...

  V = 1/3π(1.5 in)²(5 in) = 3.75π in³ ≈ 11.78 in³

The cone can hold about 11.78 cubic inches of liquid.

Answer:

The value of x = 5

The value of z = 107

Step-by-step explanation:

=> (6x+43)° +107° = 180° { linear pair }

=> 6x+43 +107 = 180

=> 6x + 150 = 180

=> 6x = 180-150

=> x = 30/6

=> x = 5

Now solve for z ,

107 = z { Vertically opposite angle }

Answer:

$152

Step-by-step explanation:

To find Yoko's hourly pay, we will divide the $323 she made after working by 17, which is the number of hours she worked:

323 ÷ 17 = 19

We now know that Yoko makes $19 an hour (dang, she's probably a doctor or something) however, we're not done yet.

We will multiply $19 by 8 hours of work to see how much she'll make after 8 hours:

19 × 8 = 152

Yoko makes $152 after 8 hours of work.

Step-by-step explanation:

f(x) = 5x - 20

f(-1) = 5(-1) - 20 = - 5 - 20

= - 25

g(x) = x² + 5x - 11

g(2) = 2² + 5(2) - 11 = 4 + 10 - 11

= 3

Thus, f(-1) + g(2) = - 25 + 3 = - 22

Answer:

Step-by-step explanation:

Substituting x as -1 in f(x), f(-1)

F(-1)=5(-1)-20

F(-1)=-5-20

F(-1)=-25

Substituting x as2 into g(x), g(2)

G(x) =2^2+5(2)-11

G(x)=4+10-11

G(x)=3

F(-1)+g(2)=-25+3

=-22

perimeter=2(85)+π(12.5)=220+2×12.5π
