The given figure consists of rectangular and triangular prisms. The birdseed that it will take to fill Sharri’s birdhouse completely is 5100

The given figure consists of rectangular and triangular prisms. The volume of the prism is expressed as:

Volume of the rectangular prism = lwh
Vr =10 * 15 *30
Vr = 4500 square cm

For the triangular prism

Vt = BH

B = 0.5 * 4 * 15
B = 30 square units

H = 20cm

Vt =20 * 30
Vt = 600 square units

Total volume = 4500 + 600 = 5100

Hence the birdseed that it will take to fill Sharri’s birdhouse completely is 5100

Step-by-step explanation:

Distance between Miami and Naples = 107 miles

Distance between Miami and Jacksonville is about three times this distance.

Distance between Miami and Jacksonville = 3 * 107 miles

= 321 miles

Landon estimates the distance between Miami and Jacksonville is about 400 miles

The estimate is too high

He should have estimated 107 miles to 110 miles which gives a total of 330 miles

Estimated 400 miles compared to 330 miles is too high

Answer:

64 m2

Step-by-step explanation:

12x6=72m2

2x4=8m2

72-8=64m2

The area for the given dimensions of Jared's classroom is, 64 m²

An area is total space occupied by two-dimensional or flat surfaces. In other words we can say that it is a number of unit squares present in a closed figure. We use various units for measurement of area like, cm², m², ft², mm².

Given that,

The dimensions of Jared's classroom are,

12 m, 4 m, 6 m, 4 m, 2 m, 8 m

we can divide the area of classroom in two parts,

first A₁, having side lengths of 6 m & 8 m

second A₂, having side lengths of 4 m & 4 m

Jared's classroom area =  A₁ +  A₂

A₁ = 6 × 8

      =  48

A₂ = 4 × 4

     = 16

A =  A₁ +  A₂

  = 16 + 48

  =  64

The area of classroom is 64 m²

Step-by-step explanation:

The right triangle formula: c^2 = a^2 + b^2

                                  c is the hypotenuse side of the triangle

                                  a and b are the legs of the triangle.    

 Find the hypotenuse :   c^2 = (24)^2 + (34)^2

                                          c = square root of (  (24)^2 + (34)^2)

                                          c = square root of ( 576 + 1,156)

                                          c = 41.6173

Answer:

{-8, -4}

Step-by-step explanation:

Rewrite this function y=x2 +12x +32 as y = x^2 + 12x + 32; " ^ " indicates exponentiation.

Set this x^2 + 12x + 32 equal to zero (to find the zeros):  

x^2 + 12x + 32 = 0.  Let's solve this using the quadratic formula, which applies when ax^2 + bx + c = 0:

       -b ± √(b^2 - 4·a·c)

x = -------------------------------

                    2a

The coefficients of the given quadratic are {1, 12, 32}.  Thus, the discriminant is

b^2 - 4ac, or 12^2 - 4(1)(32), or 144 - 128, or 16. Therefore, we have:

       -12 ± √16                                                     -12 ± 4

x = --------------------    which simplifies to:    x = --------------- = { -8, -4}

              2                                                                  2

The zeros are {-8, -4}

Answer:

it takes the bears 12 days to eat honey together.

Step-by-step explanation:

1/x+9+1/x+16=1/x

(solve this using cross multiplication)

= x^2 = 144

x=12

answer: 12

explanation:

let x=two bears eating honey together

let x+9=first bear

let (x+9)+7=second bear     **because we know the second day takes 7 more days to eat the same amount of honey as the first bear**

since the bears can finish a barrel of honey over multiple days, they can only finish part of the barrel of honey in one day.

therefore...

x/(x+9)+x(x+16)=1 or x*1/(x+9)+x*1/(x+16)=1     **the equation equals 1 because you are trying to find how much honey they eat in one day aka 1=single day**

if you solve, you get x=-12; x=12. it can only be the positive value so x=12 is your answer. your welcome fellow rsm students.

Answer:

The theoretical probability is 1/18

Step-by-step explanation:

Firstly, we need to know the total number of possible results

By rolling two cubes, there are a total of 36 possible results

Now, the sum of 3 can be gotten by the addition of 1 to 2 or 2 to 1

If we have 1 on the first cube and 2 on the second, we have the correct sum

we can also have 2 on the first cube and 1 on the second

This gives a total of 2 possible ways of getting 3

The probability can be calculated by dividing the number of ways to get 3 by the total number of possible results

we have this simply as 2/36 = 1/18

Hey there! I  have this same question, but i think you typed it wrong. A rectangular prism has a length of 1 1/4cm, not 114. A width of 4 cm, and a height of 3 1/4 cm, not 314. The answer to this question would be 16.25 cubic cm, but if you typed it right, then you should use the other answer.  Hope this helped!!
