Answer:

Sorry if this is wrong but I think they ran at the same pace

Step-by-step explanation:

So if it is 1/6 then you do 60 divided by 6 it is ten then 60 divided by 5 is 12 so 1/5 is 12 and 1/6 is ten add it it is 60 the subtract it by 12 five times it is zero sorry if wrong

The volume of the square base pyramid is 588 ft³

The Volume of the rectangular prism is 120 ft³

The Volume of a rectangular pyramid is 360 ft³

<h3>What is volume of a shape?</h3>

Volume can be defined as the 3-dimensional space enclosed by a boundary or occupied by an object.

Volume of a square base pyramid = 1 / 3 × B × h

where

B = base area

Therefore,

Volume of a square base pyramid = 1 / 3 × 7² × 12

Volume of a square base pyramid = 1764 / 3 = 588 ft³

Volume of a rectangular prism = lwh

Volume of a rectangular prism =  6 × 5 × 4 = 120 ft³

Volume of a rectangular pyramid = 1 / 3 lwh

Volume of a rectangular pyramid = 1 / 3 × 10 × 12 × 9 = 1080 / 3 = 360 ft³

Determine the 42nd term of the sequence<br>12, 14, 16, ....​
Maslowich

Answer:

94

Step-by-step explanation:

the general formula for the nth term of this arithmetic sequence is

a(n) = 12 + 2(n-1).

The 42nd term would then be a(42) = 12+ 2(42 - 1) = 12 + 82 = 94

Please for the love of god anwser my question lay correctly I really need your help :( I will give 25 points :)! This is geometr
tangare [24]

Answer:

\displaystyle \rm  A_{ \text{c  - pentagon}} =41

\rm \displaystyle P _{ \rm c - pentagon} =  20+ 4 \sqrt{2}

Step-by-step explanation:

we have a square and a triangle

we want to figure out the area and the perimeter of the pentagon

to figure out the area of the pentagon we can use the given formula:

\displaystyle \rm  A_{ \text{c  - pentagon}} = A_{ \text{squre}} - A_{ \text{triangle}}

let's figure out A_{\rm square}:

since the given shape is a square Every angle of its 90° Thus the triangle is a right angle triangle

therefore the height is 4

\displaystyle A _{ \rm triangle} =  \frac{1}{2}  \times b \times h

substitute h and b

\displaystyle A _{ \rm triangle} =  \frac{1}{2}  \times 4 \times 4

reduce fraction:

\displaystyle A _{ \rm triangle} =   2 \times 4

simplify multiplication:

\displaystyle A _{ \rm triangle} =   8

likewise square

\displaystyle A _{ \rm squre} =  {s}^{2}

substitute s:

\displaystyle A _{ \rm squre} =  {7}^{2}

simplify square

\displaystyle A _{ \rm squre} =  49

hence,

\displaystyle \rm  A_{ \text{c - pentagon}} =49- 8

\displaystyle \rm  A_{ \text{c  - pentagon}} =41

to figure out perimeter

let's figure out hypotenuse first

\displaystyle h =  \sqrt{ {4}^{2}   +  {4}^{2} }

\displaystyle h =  \sqrt{ 16  +  16}

\displaystyle h = 4 \sqrt{2}

therefore,

\rm \displaystyle P _{ \rm c - pentagon} = 3 + 3 + 4 \sqrt{2}  + 7 + 7

\rm \displaystyle P _{ \rm c - pentagon} = 6 + 4 \sqrt{2}  + 14

\rm \displaystyle P _{ \rm c - pentagon} =  20+ 4 \sqrt{2}

Slope is -2/5 and the y-intercept is 100
Mrrafil [7]

Answer:

y=-\frac{2}{5}+100

Step-by-step explanation:

With the given information, we can write the line equation in slope intercept form. y=mx+b

The slope, m, is -2/5

The Y-intercept, or b, is 100.

Replace m with -2/5 and b with 100.

y=mx+b\\y=-\frac{2}{5}x+100
