Mrs. Hales then tells Kyle to write an equation showing that the volume, V, of each of his prisms is equal to l × w × h

Answer:

[tex]a_{n}[/tex] = 1.3n - 4.7

Step-by-step explanation:

There is a common difference d between consecutive terms

d = - 2.1 - (- 3.4) = - 0.8 - (- 2.1) = 0.5 - (- 0.8) = 1.8 - 0.5 = 1.3

This indicates the sequence is arithmetic with nth term ( explicit rule )

[tex]a_{n}[/tex] = a₁ + (n - 1)d

where a₁ is the first term and d the common difference

Here a₁ = - 3.4 and d = 1.3 , then

[tex]a_{n}[/tex] = - 3.4 + 1.3(n - 1) = - 3.4 + 1.3n - 1.3 = 1.3n - 4.7

A recursive rule allows a term in the sequence to be found by adding d to the previous term, that is

[tex]a_{n}[/tex] = [tex]a_{n-1}[/tex] + 1.3 : a₁ = - 3.4

Answer:

Slope, sometimes referred to as gradient in mathematics, is a number that measures the steepness and direction of a line, or a section of a line connecting two points, and is usually denoted by m. Generally, a line's steepness is measured by the absolute value of its slope, m.

Step-by-step explanation:

use Pythagorean's theorem a²+b²=c²

so 9²+12²=15²

Answer:

the third one

Step-by-step explanation:

the y-intercept is -2 with a slope of 1/3

Step-by-step explanation:

Since, The formula of Pythagoras is A² + B² + C²

(therefore)* let A be 8 mm

B be 6 mm

Therefore, 8² + 6² = 64 + 36

= 100

= 10( after squaring it )

Step-by-step explanation:

difference means subtraction, in in order to avoind PEMDAS making it the difference of 3 times 8 and x, you need to add parentheses.

sorry if that made no sense lol

Answer:

A. 3(8-x)

Step-by-step explanation:

the difference means subtracting and the times means multiple

to multiple the difference of 8 and x, you must find a way to changed the order in a way that one portion is solved before the other. you must add parenthesis to force 8 to subtract from x before 8 can be multiplied by 3.

therefore 3(8-x)

Answer:

Volume left = 404.32 cubic inches

Step-by-step explanation:

volume of a cylinder = [tex]\pi[/tex][tex]r^{2}[/tex]h

volume of ice cream in the cylindrical tub = [tex]\frac{22}{7}[/tex] x [tex]5^{2}[/tex] x 9

                                           = [tex]\frac{22}{7}[/tex] x 25 x 9

                                           = 707.1429

Volume of ice cream in the cylindrical tub is 707.14 cubic inches.

The ice cream scoop has a spherical volume, so that;

volume of a sphere = [tex]\frac{4}{3}[/tex][tex]\pi[/tex][tex]r^{3}[/tex]

r = [tex]\frac{2.5}{2}[/tex]

 = [tex]\frac{5}{4}[/tex] inches

volume of the scoop = [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](\frac{5}{4} )^{3}[/tex]

                                  = [tex]\frac{4}{3}[/tex] x [tex]\frac{22}{7}[/tex] x [tex]\frac{125}{64}[/tex]

                                  = 8.1845

volume of the scoop is 8.19 cubic inches.

If he scoops 37 scoops,

volume of the 37 scoops = 37 x 8.1845

                                          = 302.8265

volume of 37 scoops is 302.83 cubic inches.

Volume of ice cream left in the tub = 707.1429 - 302.8265

                                                           = 404.3164

Volume of ice cream left in the tub is 404.32 cubic inches.

Answer:

109

Step-by-step explanation:

Formula

<ZHG + <IHZ = <IHG

Givens

<ZHF = 11x - 1

<IHZ = 24

<IHG = 12x + 13

Solution

11x - 1 + 24 = 12x + 13             Combine terms on the left

11x + 23 = 12x + 13                  Subtract 13 from both sides

     - 13             - 13  

11x + 10 = 12x                           Subtract 11x from both sides

-11x           -11x

        10 =   x

Answer

11x - 1 = 11*10 - 1 = 110 - 1 = 109

Answer:

Joe hit 11 balls       Roy hit 41

Step-by-step explanation

Joe = J

Roy = 4J-3 (4times Joe  less 3)

J+ 4J-3 = 52

5J -3 = 52

Add 3 on both sides  

5J = 55

Divide both sides by 5

J= 11

Joe = 11

11X4 = 44

44-3 = 41

Roy 41

11+41 = 52

Answer:

X=80

Step-by-step explanation:

I suppose the graph will be like this:

Since isosceles trapezoid, red lines are parallel.

X+x+20= 180

2x+20=180

2x=160

X=80

Given:

The table of values of a linear function.

To find:

The equation of linear function in slope intercept form.

Solution:

The slope intercept form of a linear function is:

[tex]y=mx+b[/tex]

Where, m is the slope and b is the y-intercept.

If a linear function passes through two point, then the equation of the linear function is:

[tex]y-y_1=\dfrac{y_2-y_1}{x_2-x_1}(x-x_1)[/tex]

Consider any two points from the given table. Let the two points are (-6,12) and (-5,14). So, the equation of the linear function is:

[tex]y-12=\dfrac{14-12}{-5-(-6)}(x-(-6))[/tex]

[tex]y-12=\dfrac{2}{-5+6}(x+6)[/tex]

[tex]y-12=\dfrac{2}{1}(x+6)[/tex]

[tex]y-12=2x+12[/tex]

Adding 12 on both sides, we get

[tex]y-12+12=2x+12+12[/tex]

[tex]y=2x+24[/tex]

Therefore, the slope intercept form for the given linear function is [tex]y=2x+24[/tex].

Answer:

A 2 ounce bag costs $1.2.

Step-by-step explanation:

With the information provided, you can use a role of three to find the cost of a 2 ounce bag given that you know that a six ounce bag costs $3.60.

6 ounce bag → 3.60

2 ounce bag →   x

x=(2*3.60)/6

x=7.20/6

x=1.2

According to this, the answer is that a 2 ounce bag costs $1.2.
