MATH!!! 15 points ;)) find the volume of the composite figure
andrezito [222]

Answer:

(2*2*1.5*1/3)+(2*1.5*4)= 14

Step-by-step explanation:

To find the area of a pyramid, you use the equation of 1/3 *lwh. When we place the values in there, we get 2*2*1.5*1/3, which is equal to 2. Then we solve the bottom part. Since it is a rectangular prism, we use the equation of lwh. When we insert the values, we get 2*1.5*4, which is equal to 12. Now, we take these two values of 2 and 12 and we combine them, giving us our final answer of 14.

In some​ country's congress, the number of representatives is 25 less than five times the number of senators. there are a total
Nataliya [291]
Let number of senators = x, then:-

number of representatives = 5x - 25  so

x + 5x - 25 = 515
6x = 540
x = 90  
number of reps =  515 - 90 = 425

so there are 90 senators and 425 representatives.

A, B, C, D, E and F are points on a circle. put crosses on the ends of the line that is a diameter of the circle
Step2247 [10]

9514 1404 393

Answer:

  AD is the diameter

Step-by-step explanation:

Angles in a triangle have a sum of 180°, so inscribed angle B is 80° and inscribed angle E is 90°.

An inscribed angle subtends an arc that is twice its measure, so arcs ABD and AED are both 180°. That makes chord AD a diameter.

Points A and D need your cross markings. AD is a diameter of the circle.

An exam has 10 problems. How many ways can (integer points be assigned to the problems if the total of the points is 100 and eac
vovikov84 [41]

Answer:

number of way is \frac{59!}{50)!9!}

Step-by-step explanation:

given data:

total number of problems 100

total points for each problem 5

let ten problems are

x_1, x_2,........., x_{10}

according to the given information

x_1 +x_2 +.......+x_{10} = 100

x_i \geq 5

where i =1 + 10

so, number of way integer point can assign are

   ^{(n+r-1)}C_{(r-1)}

where

r = 10

n = 100 - 10\times 5 = 50

so, we have

^{(59)}C_{9}

\frac{59!}{59-9)!9!}

number of way is \frac{59!}{50)!9!}
