Answer: None

Step-by-step explanation:

There are no pairs of congruent sides, so the triangles cannot be proven congruent.

Answer:

D. 8x - 3

Step-by-step explanation:

Simply add all the sides up - 2x+3x+3x - 1+1+1 = 8x - 3

Answer: $26

Step-by-step explanation:

   If $19.50 is 3/4, we need to find 4/4.

3/4 -> 0.75

4/4 -> 1

    We will set up a proportion and solve.

[tex]\frac{19.5}{0.75} =\frac{x}{1}[/tex]

19.5 = 0.75x

26 = x

         The professional ball is $26.

Answer:

$26

Step-by-step explanation:

19.50 = 3/4

so

to find 1/4, we do 19.50 / 3 = 6.5

6.5 = 1/4

so the price of a professional ball would be 4/4 (1 whole)

6.5 x 4 = 26

Hope this makes sense.

The recursive definition for the geometric sequence is given as follows:

[tex]a_n = 3a_{n-1}, a_1 = 1.7[/tex]

A geometric sequence is a sequence in which the result of the division of consecutive terms is always the same, called common ratio q.

The nth term of a geometric sequence is given by:

[tex]a_n = a_1q^{n-1}[/tex]

In which [tex]a_1[/tex] is the first term.

The recursive definition of a geometric sequence is given by:

[tex]a_n = qa_{n-1}[/tex]

In this problem, we have that the first term and the common ratio are given, respectively, by:

[tex]a_1 = 1.7, q = \frac{15.3}{5.1} = \frac{5.1}{1.7} = 3[/tex].

Hence the recursive definition is given by:

[tex]a_n = 3a_{n-1}, a_1 = 1.7[/tex]

The volume of the triangular prism is 108 in³

Step-by-step explanation:

Formula used

Volume of a prism = base area × height

Area of a rectangle = width × length

Area of a triangle = 1/2 × base × height

Volume of a cube = s³  (where s is the side length)

---------------------------------------------------------------------------------------------------

⇒ Volume of Figure A = (5 · 7)(2)

                                     = 70 cm³

⇒ Volume of Figure B = (13 · 7)(2)

                                     = 182 cm³

⇒ Total Volume = Volume of Figure A + Volume of Figure B

                           = 70 + 182

                           = 252 cm³

The first statement is false.

Rewritten statement:

The volume of figure A can be found by multiplying (5 · 7)(2).

---------------------------------------------------------------------------------------------------

⇒ Volume of rectangular prism = (15 · 15)(2)

                                                    = 450 mm³

⇒ Volume of central cube = 2³

                                            = (2 · 2 · 2)

                                            = 8 mm³

⇒ Total Volume = Volume of rectangular prism - Volume of cube

                           = 450 - 8

                           = 442 mm³

The third statement is false.

Rewritten statement:

The total volume of the figure is 442 mm³

---------------------------------------------------------------------------------------------------

⇒ Volume of rectangular prism = (12 · 3)(8)

                                                    = 288 in³

⇒ Volume of triangular prism = (1/2 · 12 · 6)(3)

                                                 = 108 in³

⇒ Total Volume = Volume of rectangular prism + Volume of triangular prism

                           = 288 + 108

                           = 396 in³

The second statement is false.

The volume of the triangular prism is 108 in³

Binomial

Step-by-step explanation:

Simplify the expression :

There are 2 terms.

Hence, it is a binomial

Answer:

Linear expression

Step-by-step explanation:

First, simplify the expression.

Given expression: [tex]9p-10q+3-9p[/tex]

Collect like terms:   [tex]9p-9p-10q+3[/tex]

Combine like terms:   [tex]-10q+3[/tex]

As each term of the expression is either a numeric constant or a variable with no exponent, this is a linear expression.

It can also be called a binomial expression since the expression only contains two terms (the constant and the variable).

Answer:

1125 m

Step-by-step explanation:

Given equation:

[tex]h=-5t^2+150t[/tex]

where:

Method 1

Rewrite the equation in vertex form by completing the square:

[tex]h=-5t^2+150t[/tex]

[tex]\implies h=-5t^2+150t-1125+1125[/tex]

[tex]\implies h=-5(t^2-30t+225)+1125[/tex]

[tex]\implies h=-5(t-15)^2+1125[/tex]

The vertex (15, 1125) is the turning point of the parabola (minimum or maximum point).  As the leading coefficient of the given equation is negative, the parabola opens downward, and so vertex is the maximum point.  Therefore, the maximum height is the y-value of the vertex: 1125 metres.

Method 2

Differentiate the function:

[tex]\implies \dfrac{dh}{dt}=-10t+150[/tex]

Set it to zero and solve for t:

[tex]\implies -10t+150=0[/tex]

[tex]\implies 10t=150[/tex]

[tex]\implies t=15[/tex]

Input found value of t into the original function and solve for h:

[tex]\implies -5(15)^2+150(15)=1125[/tex]

Therefore, the maximum height is 1125 metres.

Convert to vertex form y=a(x-h)²+k

Vertex at (15,1125)

As a is negative parabola is opening downwards hence vertex is maximum

Area:-

Answer:

408 ft²

Step-by-step explanation:

Given that,

→ Length (l) = 12 ft

→ Breadth (b) = 34 ft

Formula we use,

→ Area of rectangle = l × b

Then the area will be,

→ l × b

→ 12 × 34

→ 408 ft²

Hence, the area is 408 ft².

We can simplify the ratio 600 : 900 by dividing both terms by the greatest common factor (GCF).

The GCF of 600 and 900 is 300.

Divide both terms by 300.

600 ÷ 300 = 2

900 ÷ 300 = 3

Answer:

x^2 + y^2 = 49

Step-by-step explanation:

The equation of a circle is given by

(h,k) is the center of the circle and r is the radius

The circle is centered and (0,0) and the radius is 7

( x-0) ^2 + (y-0) ^2 = 7^2

Since the unit rate of Tito is greater than that of Jonah, hence Tito is running at a faster rate

The ratio of distance covered by an object to tme taken is unit rate.

Calculate the unit rate for both Jonah and Tito

For Jonah

Unit rate = 5laps/9minutes

Unit rate = 0.56 laps per minute

For Tito

Unit rate = 7laps/11.2minutes

Unit rate = 0.625laps per minute
