A formula for the volume of a pyramid is V = 3 . which expression can be used to find V, the
volume of the pyramid, in cubic inches?

Answer:

A:  angle A is 90°, angle B is 90°, angle C is 90°, and angle D is 90°

B:  angle A is 80°, angle B is 80°, angle C is 100°, and angle C is 100°

D:  angle A is 60°, angle B is 50°, angle C is 120°, and angle D is 130°

Step-by-step explanation:

The sum of opposite angles of a cyclic quadrilateral is 180°

It must satisfy the following:

A+C=180° and B+D=180°

Only choice A and B and D satisfy.

The correct options are options A, B, and D.

A quadrilateral having all its corners on a circle plus opposite angles' sum is 180° called a cyclic quadrilateral.

A) ∠A =90°

∠B=90°

∠C =90°

∠D =90°

∠A + ∠C = 180°

∠B + ∠D =180°

So, this quadrilateral can come from a cyclic quadrilateral.

B) ∠A =80°

∠B=80°

∠C =100°

∠D =10 0°

∠A + ∠C = 180°

∠B + ∠D =180°

So, this quadrilateral can come from a cyclic quadrilateral.

Similarly, options C, D, and E also can be checked whether they can come from a cyclic quadrilateral or not.

C) Cannot come from a cyclic quadrilateral since ∠A + ∠C =140°≠180°.

D) ∠A + ∠C = 180°

∠B + ∠D =180°

So,  this quadrilateral can come from a cyclic quadrilateral.

E)Cannot come from a cyclic quadrilateral since∠A + ∠C = 170°≠180°.

Therefore, The correct options are options A, B, and D.

Each new number adds 10 (you could also write the equation 3 + 10n where n is the position of the number in the sequence)

The blanks are 23 and 43

Step-by-step explanation:

In two numbers it goes up by 20, so in one it will go up by 10.

This means the blanks are 13 + 10 = 23 and 33 + 10 = 43

Answer:

a)(4+x) + (4+x) + x= 26

b) x=6

Step-by-step explanation:

pavan=x

brother 1=4+x

brother 2=4+x

brother 1=brother 2

a)

(4+x) + (4+x) + x= 26

b)

(4+x) + (4+x) + x= 26

=> 8+3x=26

=>

take 8 to 26

=>

3x=26-8=18

take 3 to 18 side

x=18/3=6

therefore pavan saves 6$ per month

Answer:

y>3x+2

Step-by-step explanation:

1. use y2-y1/x2-x1 to find the slope (3)

2. since the y-intercept is already give as (0,2) we have the equation y=3x+2

3. finally since the left side is shaded, that would mean everything greater than that equation can equal y therefore y>3x+2

Answer:

[tex]Length = 98[/tex]

Step-by-step explanation:

Given

[tex]AO = 5x - 1[/tex]

[tex]BO = 4x + 9[/tex]

Required:

The length of the diagonal

Since AO and BO are diagonals that meets at O, we have:

[tex]AO=BO[/tex]

This gives

[tex]5x - 1 = 4x + 9[/tex]

Collect Like Terms

[tex]5x - 4x = 1 + 9[/tex]

[tex]x = 10[/tex]

Subsitute 10 for x in [tex]AO = 5x - 1[/tex]

[tex]AO = 5 * 10 - 1[/tex]

[tex]AO = 50 - 1[/tex]

[tex]AO = 49[/tex]

The length of the diameter is:

[tex]Length = AO * 2[/tex]

[tex]Length = 49 * 2[/tex]

[tex]Length = 98[/tex]

Answer:

adult tickets = 118

student tickets = 354

Step-by-step explanation:

a = number of adult tickets

s = number of student tickets

a + s = 472

3a = s

substitute for s

a + 3a = 472

reduce

4a = 472

divide by 4

4a/4 = 472/4

a = 118

s = 354

a. Slope of 0.536 means that when there is an increase in carbohydrate content, there will be sn increase in 0.536 grams of sugar content.

b. Coefficient of Determination, R^(2) = 0.544^(2) = 0.295936 = 0.296. Percent of variation = 29.6

c. For carbohydrate content of 29 grams,

Predicted amount of sugar per cup for Raisin Bran = -5.10 + 0.536*29 = 10.444 gram

d. Residual value= Actual value - Predicted value

8.556 = Actual sugar content - 10.444

Actual sugar content = 8.556 +10.444

Actual sugar content = 19

So, the Raisin Bran actually have 19 grams of sugar per cup.

Answer: It is 136.

Step-by-step explanation:

2 kilometers to 72 meters simplest form is 1:36.

Suppose the  real measurements were "a" and "b"

Then their ratio will be formed as

[tex]\dfrac{a}{b} = \dfrac{p \times x}{q \times x} = \dfrac{p}{q}[/tex]

where x is a common factor (not 1)

This shows that to get the real measurements from the given ratio, we need to assume to have some factor possibly cancelled from both the numerator and the denominator.

Thus, a = px, b = qx

1. To Find common denominator:

2 x 2/ 72 x 2

Commonest denominator: 2

2. Divide the two terms:

2 x 2 = 2/ 72 = 36

3. Convert into rate form:

1:36

Therefore, 2 kilometers to 72 meters simplest form is 1:36.

Answer:

60

Step-by-step explanation:

last year 1/5 of the class played sports, so s = (1/5) c

the next year, s increased by 5, c increased by 10 and the fraction changed to 1/4, so for the next year (s+5) = (1/4)(c+10)

To solve this we can substitute s = (1/5)c from the first equation into the second, so

((1/5)c + 5)=(1/4)(c+10), simplify both sides

(1/5)c + 5 = (1/4)c + 10/4, simplify 10/4 to 5/2

(1/5)c + 5 = (1/4)c + 5/2, multiply both sides by 20 to eliminate fractions (least common multiple of 2, 4 and 5)

4c + 100 = 5c + 50, subtract 4c, subtract 50 from both sides

50 = c, number of students in class last year was 50, this year is 10 more, so this year is 60
