Step-by-step explanation:

By proportion:

80 %      is equivalent to  32 questions

So 100%  ..   ..   ..  ..   ..  ..   (32/80) * 100

= 32 * 5/4

= 160/4

= 40

Answer:

40

Step-by-step explanation:

80/100=32/x

The option (C) LA and (D) ASA are correct because two angles and one side are the same.

Congruent triangles are those that are exactly the same size and shape. Congruent is represented by the symbol ≅ When the three sides and three angles of one triangle match the dimensions of the three sides and three angles of another triangle, they are said to be congruent.

From the triangle DEF and triangle JKL

∠D = ∠J  (given)

∠F = ∠L  (given)

ED = KJ  (given)

∴ Triangle DEF and triangle JKL are congruent by the ASA

ΔDEF≅ΔJKL

Also:

∠F = ∠L  (given)

ED = KJ  (given)

ΔDEF≅ΔJKL by LA

Thus, the option (C) LA and (D) ASA are correct because two angles and one side are the same.

Answer:

Looking at the given points we know that it is going to be rectangle because we have 4 points.  Therefore the figure is a rectangle and the area formula would be [tex]A=l*w[/tex].

You can look at the attached graph and what we see is that our width of the rectangle is from [tex]y=-4[/tex] to [tex]y=3[/tex] which means that our height is 7 units wide.  We can also see that our length starts at [tex]x=-1[/tex] and ends at [tex]x=4[/tex] making us have a length of 5 units.

We then plug in the values and solve

[tex]A = 7\ units * 5\ units[/tex]

[tex]A = 35\ units^2[/tex]

Therefore, the area of our rectangle is [tex]35\ units^2[/tex]

➛ [tex] 22 \times 300 [/tex]

➛ [tex] { \boxed{ \green{6600{ \rm{ {cm}^{3}}} }}} [/tex]

Thus, The volume of Cylindrical Tank is[tex]{ \bold{ \: 6600{ { \bold{ {cm}^{3}}} }}}[/tex].

The correct statement is the first one. g(x) exceeds f(x) by 72.

By looking at the table, we can see that f(x) is a linear function and g(x) is an exponential function, such that:

f(x) = 10 + 3x

g(x) = (1/2)^x

By evaluating these functions in x = -6 we get:

[tex]f(-6) = 10 - 3*6 = -8[/tex]

[tex]g(-6) = (1/2)^{-6} = 64[/tex]

The difference is:

g(-6) - f(-6) = 64 + 8 = 72

Then the correct option is the first one, g(x) exceeds f(x) by 72.

The value of each book in the set will be $6.5 when he sold his books to the second hand store.

When we sell any product above its cost price then there will be profit if the selling price is less then the cost price then there will be loss on the product.

here the total cost of the books sold will be given as:-

[tex]\$29.75+ \$2.75 =\$ 32.5[/tex]

The cost of the each book will be

Step-by-step explanation:

The probability that the number is not a prime number is 5/9.

Probability refers to potential. A random event's occurrence is the subject of this area of mathematics.

The range of the value is 0 to 1. Mathematics has incorporated probability to forecast the likelihood of various events.

The degree to which something is likely to happen is basically what probability means.

Given:

Paul is thinking of a number that is greater than 10 and less than 20.

So, the prime number between 10 and 20 are 11, 13, 17, 19.

So, the probability that the number is not a prime number

= ( 9- 4)/ 9

= 5/9

Hence, the probability that the number is not a prime number is 5/9.

By analyzing the polynomial we have the following conclusions about the five propositions:

1) True

2) True

3) False

4) False

5) True

In this question we have a second order polynomial with two variables (x, y) and we need to determine the truth value of each proposition by applying concepts related to polynomials.:

1) There are four terms - A term is an additive component of the polynomial. Thus, the polynomial has four terms. (True)

2) 6 · x² and 3 · x are like terms - Two components are like terms if they have the same variable. Thus, 6 · x² and 3 · x are like terms. (True)

3) The coefficient on y is 14 - A coefficient is a constant that accompanies a variable. The constant of y is -14. (False)

4) Simplified, the expression is 6 · x² + 5 · x - 14 · y - The simplification of the polynomial is done by applying algebraic properties. The simplified form is 6 · x² + x - 14 · y. (False)

5) The commutative property allows the expression to be written as 6 · x²  - 14 · y + 3 · x - 2 · x - Commutative property indicates that the order of components of the polynomial can be changed without changing the result of the entire polynomial. (True)

The statement is incomplete and incorrectly formatted. Correct statement is shown below:

Determine the truth value of each statement based on the expression 6 · x² - 2 · x - 14 · y + 3 · x.

1) There are four terms.

2) 6 · x² and 3 · x are like terms.

3) The coefficient on y is 14.

4) Simplified, the expression is 6 · x² + 5 · x - 14 · y.

5) The commutative property allows the expression to be written as 6 · x²  - 14 · y + 3 · x - 2 · x.

The statement first, statement second, and statement sixth are true.

It is defined as a three-dimensional space enclosed by an object or thing.

We have:

The original prism has a length of 3 inches, a width of 2 inches, and a height of 1 inches.

The new length = 3+2 = 5 inches

The new width = 2+2 = 4 inches

The new height = 1+2 = 3 inches

The volume of the old prism  = 3×2×1 = 6 cubic inches

The volume of the new prism = 5×4×3 = 60 cubic inches

Srekar, could increase the volume by the same amount by just adding 6 to the height instead of 2 to each side is false becasue:

Volume = 3×2×(1+6) = 42 cubic inches

The volume of the new prism will be 20 times 3 = 60 because there will be 20 cubes in each layer and the height will be 3 so there will be 3 layers of 20 cubes each is true.

Thus, the statement first, statement second, and statement sixth are true.

Explanation:

In other words,

N is some positive whole number.

Add up all those expressions and set the sum equal to the 150 books total. Solve for N.

(1st stack) + (2nd stack) + (3rd stack) = total

(2N+30) + (2N) + (N) = 150

(2N+2N+N) + 30 = 150

5N + 30 = 150

5N = 150-30

5N = 120

N = 120/5

N = 24 which is the number of books in the 3rd stack

2N = 2*24 = 48 is the number of books in the 2nd stack.

2N+30 = 2*24+30 = 48+30 = 78 books in the 1st stack

Check:

1st+2nd+3rd = 78+48+24 = 150
