Answer:

64

Step-by-step explanation:

If you measure the cubes inside for the length, width and height, you get:

Length - 5 cubes

Width -5 cubes

Height - 3 cubes

The volume of the prism is 5 * 5 * 3 = 75. This means the prism can hold a total of 75 cubes

The amount of cubes already in there is 11

so 75 - 11= 64

Answer:

Step-by-step explanation:

L=2W+4

P=2(L+W), using L from above makes this

P=2(2W+4+W)

P=2(3W+4)

P=6W+8

6W=P-8

W=(P-8)/6, since we are told P=26

W=(26-8)/6

W=18/6

W=3 cm, and since L=2W+4

L=2(3)+4

L=6+4

L=10 cm

So the dimensions of the envelope with a perimeter of 26cm is 3cm by 10cm

Answer:

g(x) = [tex]2^{x}[/tex] + 3

Step-by-step explanation:

Given f(x) then f(x) + c is a vertical translation of f(x)

• If c > 0 then a shift up of c units

• If c < 0 then a shift down of c units

Here the shift is 3 units up, then

g(x) = [tex]2^{x}[/tex] + 3

Answer:Number of students eating lunches other than salads or sandwiches= 10

Step-by-step explanation:

Number of students in the cafeteria=20

Number of students eating salads=1/10 X 20= 2

Number of students eating sandwiches= 2/5 x 20 = 8

Number of students eating lunches other than salads or sandwiches=

Number of students in the cafeteria -(

Number of students eating salads +Number of students eating sandwiches)

=20-(2+8)

=20-10

=10 students.

Answer:

Option D, the volume is 15.625 cubes

Step-by-step explanation:

For a cube of side length L, the volume is:

V = L^3

for the smaller cubes, we know that each one has a side length of 1 in, then the volume of each small cube is:

v = (1in)^3 = 1 in^3

Then:

1 in^3 is equivalent to one small cube

Here we know that the side length of our cube is (2 + 1/2) in

Then the volume of this cube will be:

V = [ (2 + 1/2) in]^3

To simplify the calculation, we can write:

2 + 1/2 = 4/2 + 1/2 = 5/2

Then:

V = ( 5/2 in)^3 = (5^3)/(2^3) in^3 = 125/8 in^3 = 15.626 in^3

This means that 15.625 small cubes will fill the prism.

So the correct option is D.

Step-by-step explanation:

If the 1st cookie cake is 8" for its diameter and the 2nd cookie cake will have twice the length diameter of the 1st cookie cake .You will do 2 × 8 to get the diameter of the 2nd cookie cake.

First cookie cake diameter is 8".

Second cookie cake's diameter is 16".

Since we need the radius to find the area of the 2nd cookie cake we're going to do 16 / 2 which equals 8 so 8 is the radius.

A=(pi)r^2

A=(pi)8^2 *to the 2nd power means times by the same number

A=(pi)64

A= (3.14)(64)

A=200.96

=200.96^2

pi= 3.14 *for this problem

Step-by-step explanation:

step 1. the volume of a cone (V) is (1/3)(pi)r^2h

step 2. V = (1/3)(pi)8^2(12)

step 3. V = (1/3)(pi)(768)

step 4. V = 256pi

step 5. V = 804.2 yd^3

Answer:

the correct answer is A

step by step explanation

Figure A is NOT a quadrilateral. Then the correct option is A.

The quadrilateral has four sides and four angles. The sum of internal angles is 360 degrees. In a quadrilateral, there are four vertices.

A rectangle's opposite sides are parallel and equal, and each angle is 90 degrees. In a rhombus, opposite sides are parallel and all sides are equal. In a parallelogram, opposite sides are parallel and equal.

Figure A is NOT a quadrilateral. Because two corners of the figure are rounded and in the quadrilateral, all the vertices are shaped.

Figure A is NOT a quadrilateral. Then the correct option is A.

Answer:

-2x + 2y = -8     is x=y+4

2x + y = 5          is x= −1/ 2 y+ 5/ 2

Step-by-step explanation:

Answer:

3x+2y=-3

Step-by-step explanation:

Slope = -3.000/2.000 = -1.500

x-intercept = -3/3 = -1

y-intercept = -3/2 = -1.50000

2x-3y=-15

Slope = 1.333/2.000 = 0.667

x-intercept = -15/2 = -7.50000

y-intercept = 15/3 = 5

Answer:

Step-by-step explanation:

Number of calories in burger = x

Number of calories in hotdog = y

y = x - 220

x + 2y = 1,420

Substitution:

x + 2 * (x - 220) = 1,420

x + 2x - 440 = 1,420

3x = 1,420 + 440

x = 1,860 / 3

x = 620 calories

y = x - 220

= 620 - 220

= 400 calories

The calories in each item are :

"Calorie cafe"

Number of calories in burger = x

Number of calories in hotdog = y

Equations:

                 y = x - 220--------------1

                 x + 2y = 1,420----------2

Substitution:

Putting Value of x in equation 1.

Therefore, the calories in each item are the number of calories in burger is 620 calories and number of calories in hotdog is 400 calories.
