What is the length of the missing side of the triangle below? (round to the nearest tenth)

Answer:

My theory is that it is a pyramid and that you have to find the volume of it??

6*7=42

42*3=126??????

????

i dont know sorry if wrong

Answer:

C=7

Step-by-step explanation:

Because it's a right angle in total we know the 2 expressions combined will equal 90.

(8c-5)+(6c-3)=90

Answer:

15

Step-by-step explanation:

use Pythagorean's theorem a²+b²=c²

so 9²+12²=15²

Answer:

13.7

Step-by-step explanation:

c^2 - b^2 = a^2

16.5^2 - 9.2^2 = a^2

272.25 - 84.64 = square root of a

square root of 187.61

= about 13.66 or 13.7

Answer:

9.2square +16.5square whole under root

Step-by-step explanation:

use a calculator sorry I don't have one on me

Answer:

y = -5/3x+8

Step-by-step explanation:

Equation: y=mx+b

You find the slope (m) by calculating the distance between the two points. For the y axis, 3 is -5 away from 8. For the x axis, 3 is 3 away from 0. You then devide y by x, which gives you -5/3.

To get the y intercept (b), you just look at the graph, where it's at 8.

God luck!

Answer:

y = -5/3x + 8

Step-by-step explanation:

Points on the graph: (0, 8) and (3, 3)

Slope:

m=(y2-y1)/(x2-x1)

m=(3-8)/(3-0)

m= (-5)/3

m= -5/3

Slope-intercept:

y - y1 = m(x - x1)

y - 8 = -5/3(x - 0)

y - 8 = -5/3x

y = -5/3x + 8

As we know that,

[tex]\bigstar \: \boxed{\sf {Area_{(Trapezium)} = \dfrac{1}{2} \times ( a + b) \times h}} \\ [/tex]

Substituting values, we get :

[tex] \longmapsto [/tex] Area = [tex]\sf \dfrac{1}{2} [/tex] × ( 60 + 40 ) × 30 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = [tex]\sf \dfrac{1}{2} [/tex] × 100 × 30 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = 1 × 100 × 15 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = 100 × 15 ft[tex] \sf ^2 [/tex]

[tex] \longmapsto [/tex] Area = 1500 ft[tex] \sf ^2 [/tex]

Therefore,

Answer:

120% = 120/100 = 1.2

Step-by-step explanation:

100 points = 100%, so 120 points = 120%

120% = 120/100 = 1.2

Answer: 117

Step-by-step explanation:

Formula for arithmetic sequence is:

= a + (n - 1)d

22nd term = a + (n - 1)d

= a + (22 - 1)d = a + 21d

where, a = 12

d = 17 - 12 = 5.

Therefore, 22nd term will be:

= a + 21d

= 12 + 21(5)

= 12 + 105

= 117

The 22nd term is 117

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:

[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.
