Answer:

Surface Area: 10.24 square feet

Step-by-step explanation:

In order to find the surface area, part the figure into 5 shapes; 1 being a square, the other 4 being equivalent triangles

Now find the area of the square, provided the dimensions 0.8 by 0.8:

A = 0.8 * 0.8 = 0.64 square feet

The area of the triangles are equivalent knowing that the share similar dimensions, 0.8 feet for the base and 6 feet for the height, so let us find the area of one at first:

A = 1/2 * 0.8 * 6 = 3 * 0.8 = 2.4 square feet

This means that the area of all 4 triangles are:

A = 2.4 * 4 = 9.6 square feet

The total surface area of this pyramid would then be the sum of the area of all 5 shapes, triangles and square:

Surface Area = 9.6 + 0.64 = 10.24 square feet

What is the product of (7 x 10^-5) x (5 x 10^-8) (7 x 10^-5) x (5 x 10^-8) = ? x 10^?

arsen [322]

Answer:

$3.5\times10^-^1^2$

Step-by-step explanation:

$(7 \times 10^-5) \times (5 \times 10^-8)$

Evaluate

$(7 \times 5)\times(10^-^5\times10^-^8)$

$35\times10^-^5^-^8$

$35\times10^-^1^3$

$35\times10^1\times10^-^1^3$

$3.5\times10^1^-^1^3$

$3.5\times10^-^1^2$

Thus, the answer is $3.5\times10^-^1^2$

a sporting good store received an order of 90 baseball caps, of which 18 were green. if 1 of the 90 caps is selected at random,

makvit [3.9K]

Visualize that out of the 90 caps, how many were green? 18 were green. So how many were not green? 90 caps - 18 caps = 72 caps. That means 72 caps were not green in that sporting good order. Therefore, the probability of one cap selected at random from the total 90 caps will not be green will be 72/90 which is roughly 0.8 or 80 percent.

The sum of twice a number and 18 less than the number is the same as the difference between -10 and the number. What is the numb

Lera25 [3.4K]

Answer:

n=-14

Step-by-step explanation:

2n+18-n=-10-n

n+18=-10-n

+n +n

2n+18=-10

-18 -18

2n=-28

/2 /2

n=-14

Five guys walk into a bar, how many ways can they sit so as to be arranged from oldest to youngest?

Ipatiy [6.2K]

There are 24 ways in which 5 guys can sit if arranged from oldest to youngest.

We have,

Five guys.

Now,

We know that,

Total number of ways to arranged around a table (n) = (n-1)!

So,

For n = 5,

I.e.

(n - 1)! = (5 - 1)! = 4!

So,

Total number of ways to arranged Five guys rom oldest to youngest (n) = (n-1)!

i.e.

= (5 - 1)! = 4!

We get,

= 4 × 3 × 2 × 1

i.e.

Total number of ways to arranged Five guys rom oldest to youngest (n) = 24.

Hence we can say that there are 24 ways in which 5 guys can sit if arranged from oldest to youngest.

Rewrite the set T = { 5a + 2b; a,b belong Z} as a list of its elements

Mamont248 [21]

Answer:

T={...,-3,-2,-1,0,1,2,3,4,....}

Step-by-step explanation:

We are given that T={5a+2b; a,b belongs Z}

We have to rewrite the given set T as a list of its elements

Substitute a=0 and b=0

Then we get 5(0)+2(0)=0

Substitute a=-1 and b=2 then we get

5(-1)+2(2)=-1

Substitute a=2 and b=0

Then , 5(2)+2(0)=10

If a=0 and b=1

Then, 5(0)+2(1)=2

Substitute a=0 and b=2

Then, 5(0)+2(2)=4

If substitute a=1 and b=1

5(1)+2(1)=7

If substitute a=-1 and b=3

Then, we get 5(-1)+2(3)=1

Then, T={...,-3,-2,-1,0,1,2,3,4,....}
