I think it's would be 5%

Step-by-step explanation:

Since 29 Books are damaged we do 29/580 and then get 0.05 and multiply by 100 and get 5 percent

Answer:

Step-by-step explanation:

Length : Breadth : height = 3 : 4 : 6

Length = 3x

Breadth = 4x

Height = 6x

Volume of cuboid = 576 sq.cm

length * breadth * height = 576

3x * 4x * 6x = 576

       72x³   = 576

             x³ = 576/72

            x³ =   8

            x³ = 2³

x = 2

Length = 3*2 = 6 cm

Breadth = 4* 2 = 8 cm

Height = 6*2 = 12 cm

Total surface area = 2*(lb + bh + hl)

                             = 2 * (6*8 + 8*12 + 12*6)

                            = 2 * (48 + 96 + 72)

                            = 2 * 216

                            = 432 sq.cm

Answer:

x=30, y=5

Step-by-step explanation:

in the first triangle, with 3 congruent angles, Since their angles are congruent l, there sides are also as well. So 8y=40 y=5. This is a right triangle so angle x and the adjacent red angle both form 90 degrees. Since the red angle is a equal angular triangle. It measures 60 degrees so 60+x=90 x=30

Answer:

Step-by-step explanation:

Lara has $12 in quarters.

4 quarters make a dollar.

To find the number of quarters she has therefore, you need to multiply the $12 by the 4 quarters in a dollar to find out the number of quarters in $12.

= 12 * 4

= 48 quarters

Multiply cost by number or friends, INCLUDING BOB, making it 4 people rather than three

18 * 4 = 72

Step-by-step explanation:

step 1. Let's call the amount of money A.

step 2. A = A¡e^(rt) (continuously compounding equation)

step 3. A = A¡e^(rt). A¡ = initial amount. r = rate, t = time.

step 4. A = 2200e^((.053)(7)

step 5. A = $3188.20

Answer:

constant monomial

Step-by-step explanation:

The polynomial, 9, has 1 term and its degree is 0. Therefore, the polynomial is a constant monomial.

The given expression is a constant monomial. Therefore, option A is the correct answer.

A polynomial is a type of algebraic expression in which the exponents of all variables should be a whole number. The exponents of the variables in any polynomial have to be a non-negative integer. A polynomial comprises constants and variables, but we cannot perform division operations by a variable in polynomials.

Here given expression is 9.

A constant monomial is a term with only a constant number. There is no variable in a constant monomial.

So, 9 is a constant monomial.

The given expression is a constant monomial. Therefore, option A is the correct answer.

Answer: 2n - 64

Step-by-step explanation:

If the vairiable n describes the unknown number, and there is twice the number, then we can use the term 2n.

We also have 64 less then that number, and less means to subtract. Therefore, the equation is 2n - 64.

Answer:

2n-64

Step-by-step explanation:

I believe this is the correct answer (Not exactly sure to be honest)

Twice a number means to multiply by 2, so you use the variable (n) and multiply it by 2. For subtracting 64, I believe you usually put it after the (2n) portion of the equation. You may have to flip it though, equation order is important and it's been a while since I've done these so apologies if it's wrong! Good Luck!

Answer:

p(7,-11)

that is the answer of the coordinates

Answer with Step-by-step explanation:

We are given that

g=3

[tex]15g-2(2g+6)[/tex] and [tex]11g-12[/tex]

We have to prove that two expressions are equivalent by evaluating the expressions given

[tex]15g-2(2g+6)[/tex]

Substitute the value of g in the given expression

[tex]=15(3)-2(2(3)+6)[/tex]

[tex]=45-2(6+6)[/tex]

[tex]=45-2(12)[/tex]

[tex]=45-24[/tex]

[tex]=21[/tex]

[tex]11g-12[/tex]

Substitute the value of g in the given expression

[tex]=11(3)-12[/tex]

[tex]=33-12[/tex]

[tex]=21[/tex]

Hence,

15g-2(2g+6) = 11g-12 when g=3

Answer:

22.)

m/8 = 15/24

8×15= 120

120÷24= 5

m=5

23.)9/p = 4/48

9×48= 432

432÷4=108

p=108

24.) 10.50÷3= 3.50

thats $3.50 per pizza.

9 pizzas= $31.50

plus one pizza aka, 31.50+3.50= $35

therefore, 10 pizzas would cost $35

26.) 5/2 = d-2/4

cross multiply:

5×4=2(d-2)

20= 2(d-2) divide both sides by 2

20÷2 = 2(d-2)÷2

10= d-2 exchange places with d and 10 and change signs

-d= -2-10

-d=-12 change the sign on both sides when the variable is negative.

d=12

Step-by-step explanation:

The slope is m = -3 / -4 = 0.75

The adding a value to x shifts the graph that many places to the left.

In g(x) you are adding 2 to x, so the graph moves 2 units to the left.

Answer:

112

Step-by-step explanation:

The interior angles of triangles always add up to 180 so you first add the two interior angles which are already given to get 68 then after that you subtract it from 180 to get the answer of 112.

Answer:

36 minutes

Step-by-step explanation:

Depth of the fjord = 1308 m

Rate at which the submersible dives = 35 meters/minute

Distance to the bottom of the fjord should be 48 m

Distance the submersible has to go underwater is [tex]1308-48=1260\ \text{m}[/tex]

Time is found by dividing the distance the submersible has to go underwater by rate at which the submersible dives

[tex]\dfrac{1263}{35}=36\ \text{minutes}[/tex]

The time taken by the submersible to dive the required distance is 36 minutes.

Answer:

4<x<12

Step-by-step explanation:

8.0+4.0=12.0

8.0-4.0=4.0 or 4

The rules of triangles is that it must be less than the sum you had when you first added 8.0and 4.0 which was 12

So therefore , 4< x < 12

Answer:

45

Step-by-step explanation:

18+27=9(2+3)=9(5)=45

The sum of the numbers 18 and 27 will be 45.

The largest factor of the two numbers which divides both the numbers is called as greatest common factor or GCF. The greatest common multiple is the common number multiplied by both numbers.

The distributive property of binary operations in mathematics generalizes the distributive law, which states that in elementary algebra, equality is always true.

Given sum is 18 + 27. The greatest common multiple between the two numbers is 9 take it common and then solve.

E = 18+27

E =9(2+3)

E =9(5)=45

Therefore, the sum of the numbers 18 and 27 will be 45.
