Mr. Ramirez purchase 20 concert tickets for a total of 225 the concert tickets cost 15 for adults and 10 for children under the age of 12 solve the system equation from part a algebraically

Answer:

Step-by-step explanBecause many objects are not regularly shaped their volume cannot be determined using a volume formula. The volume of these objects can be found by water displacement. A volume of water sufficient to cover the object is placed in a graduated cylinder and the volume read. The object is added to the cylinder and the volume read again. The difference between the two volumes is the volume of the object. This method is demonstrated using the same battery used above.

D1=25°

B3=25°

B1=30°

Step-by-step explanation:

1. O1+O2=360°(revolution)

310°+O2=360°

O2=360°-310°

=50°

O2=2D1(centre theorem)

50°=2D1

D1=25°

2. D1=B3=25°(tan chord theorem)

3. B2+B3=A=60°(tan chord theorem)

B1+B2+B3=90°(Radius perpendicular Tangent)

B1+60°=90°

B1=90°-60°

=30°

Answer:

Area = 9(7w -1) cm²

Step-by-step explanation:

Area of a triangle is given by the expression,

Area = [tex]\frac{1}{2}(\text{Base})(\text{height})[/tex]

From the picture attached,

Base of the triangle = 18 cm

Height of the triangle = Vertical distance of the third vertex from the base joining other two vertices = (7w - 1)

Area = [tex]\frac{1}{2}(18)(7w-1)[/tex]

        = 9(7w - 1) square cm

Therefore, expression for the area of the given triangle will be,

Area = 9(7w -1) cm²

Answer:

C

Step-by-step explanation:

Answer:

[tex] \displaystyle V_{ \text{pyramid}}= 64 \: {cm}^{3} [/tex]

Step-by-step explanation:

we are given surface area and the length of the square base

we want to figure out the Volume

to do so

we need to figure out slant length first

recall the formula of surface area

[tex]\displaystyle A_{\text{surface}}=B+\dfrac{1}{2}\times P \times s[/tex]

where B stands for Base area

and P for Base Parimeter

so

[tex] \sf\displaystyle \: 144=(8 \times 8)+\dfrac{1}{2}\times (8 \times 4) \times s[/tex]

now we need our algebraic skills to figure out s

simplify parentheses:

[tex] \sf\displaystyle \: 64+\dfrac{1}{2}\times32\times s = 144[/tex]

reduce fraction:

[tex] \sf\displaystyle \: 64+\dfrac{1}{ \cancel{ \: 2}}\times \cancel{32} \: ^{16} \times s = 144 \\ 64 + 16 \times s = 144[/tex]

simplify multiplication:

[tex] \displaystyle \: 16s + 64 = 144[/tex]

cancel 64 from both sides;

[tex] \displaystyle \: 16s = 80[/tex]

divide both sides by 16:

[tex] \displaystyle \: \therefore \: s = 5[/tex]

now we'll use Pythagoras theorem to figure out height

according to the theorem

[tex] \displaystyle \: {h}^{2} + (\frac{l}{2} {)}^{2} = {s}^{2} [/tex]

substitute the value of l and s:

[tex] \displaystyle \: {h}^{2} + (\frac{8}{2} {)}^{2} = {5}^{2} [/tex]

simplify parentheses:

[tex] \displaystyle \: {h}^{2} + (4 {)}^{2} = {5}^{2} [/tex]

simplify squares:

[tex] \displaystyle \: {h}^{2} + 16 = 25[/tex]

cancel 16 from both sides:

[tex] \displaystyle \: {h}^{2} = 9[/tex]

square root both sides:

[tex] \displaystyle \: \therefore \: {h}^{} = 3[/tex]

recall the formula of a square pyramid

[tex]\displaystyle V_{pyramid}=\dfrac{1}{3}\times A\times h[/tex]

where A stands for Base area (l²)

substitute the value of h and l:

[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{3}\times \{8 \times 8 \}\times 3[/tex]

simplify multiplication:

[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{3}\times 64\times 3[/tex]

reduce fraction:

[tex] \sf\displaystyle V_{ \text{pyramid}}=\dfrac{1}{ \cancel{ 3 \: }}\times 64\times \cancel{ \: 3}[/tex]

hence,

[tex] \sf\displaystyle V_{ \text{pyramid}}= 64 \: {cm}^{3} [/tex]

8 - 19x = 65

-19x = 65 - 8

-19x = 57

Answer:

x = -1, 7

Step-by-step explanation:

Given question is incomplete; find the complete question in the attachment.

x² - 6x - 7 = 0

Step 1,

Isolate the constant by ADDING 7 both the sides of the equation.

x² - 6x - 7 + 7 = 0 + 7

x² - 6x = 7

Step 2

Add 9 to both sides of x² - 6x = 7 to form a perfect square trinomial while keeping the equation balanced.

x² - 6x + 9 = 7 + 9

Step 3

Write the trinomial x² - 6x + 9 as (x - 3) squared.

x² - 2(3)x + 9 = 16

(x - 3)² = 4²

Step 4

Use the square root property of the equality to get x - 3 = ± 4

(x - 3)² = 4²

[tex]\sqrt{(x-3)^2}=\sqrt{4^2}[/tex]

(x - 3) = ±4

Step 5

Isolate the variable to get solution of -1 and 7

x - 3 = ± 4

x = -3 ± 4

x = -1, 7

Answer:

1. Isolate the constant by adding 7 to both sides of the equation.

2. Add 9 to both sides of x2 – 6x = 7 to form a perfect square trinomial while keeping the equation balanced.

3. Write the trinomial x2 – 6x + 9 as  x – 3 squared.

4. Use the square root property of equality to get x – 3 = ± 4.

5. Isolate the variable to get solutions of –1 and 7.

Answer:

b = 19

Step-by-step explanation:

To make it short and sweet, since one angle is 45 degrees and one angle is 90 degrees, the unknown angle is 45 degrees also. That makes it an isosceles triangle with both legs equal.

b = 19

Answer:

30 ft

Step-by-step explanation:

This situation forms a right triangle

a ² +b ²= c ²

50 ² + 40 ²= c ²

2,500 + 1,600 = c ²

900  = c ²

√900 = √c²

30 = c

Answer:

[tex]\boxed {\boxed {\sf 250 \ people}}[/tex]

Step-by-step explanation:

Let's set up a proportion using the following setup.

[tex]\frac {buses}{people}=\frac {buses}{people}[/tex]

We know 30 buses can carry 1,500 people.

[tex]\frac {30 \ buses}{1500 \ people}=\frac {buses}{people}[/tex]

We don't know how many people 5 buses can carry, so we say 5 buses carry x people.

[tex]\frac {30 \ buses}{1500 \ people}=\frac {5 \ buses}{x \ people}[/tex]

[tex]\frac {30 }{1500 }=\frac {5 }{x }[/tex]

Cross multiply. Multiply the numerator of the first fraction by the second fraction's denominator. Then, multiply the first denominator by the second numerator.

[tex]30*x=1500*5\\30x=7500[/tex]

Solve for x. It is being multiplied by 30. The inverse of multiplication is division. Divide both sides by 30.

[tex]30x/30=7500\\x=250[/tex]

5 buses can carry 250 people.

Answer:

65

Step-by-step explanation:

<S = <t

x + 50 = 3x + 20

2x = 30, x = 15

. <t = <v

3x + 20 = 45 + 20 =  65

Answer:

b.  65 degrees.

Step-by-step explanation:

m < RST = m < STU (alternate angles), so

x + 50 = 3x + 20

50 - 20 = 3x - x

2x = 30

x = 15.

Now m < RVT = m < RST  ( opposite sides of a parallelogram are equal).

So m < RVT = x + 50 = 15 + 50 = 65.

Answer:

A. m(arc BC) = 16°

B. m(arc BAC) = 344°

Step-by-step explanation:

From the picture attached,

AB is the diameter of the circle.

Since, measure of an arc is always same as the central angle of arc.

Therefore, m(arc AC) = m(∠ADC) = 164°

m(arc AB) = 180°

m(arc BC) = 360° - m(arc AB) + m(arc AC)

                = 360° - (180° + 164°)

                = 360° - 344°

                = 16°

m(arc BAC) = m(arc AB) + m(arc AC)

                   = 180° + 164°

                   = 344°

Answer:

add all of the angles together and set them equal to 360 and solve
