Answer:

(C) Sophie used the wrong height for the pyramid.

Step-by-step explanation:

she should have subtracted 4 from 30 because that was apart of the prism

The total volume is 7448  cubic millimeters. Sophie has made mistake in copying height of pyramid.

Volume is the measure of the capacity that an object holds.

Formula to find the volume of the object is Volume = Area of a base × Height.

Given that, a rectangular prism with a length of 28 millimeters, width of 21 millimeters, and height of 4 millimeters.

Volume of rectangular prism = Length×Width×Height

= 28×21×4

= 2352 cubic millimeters

A rectangular pyramid with a base of 28 millimeters by 21 millimeters and height of 26 millimeters.

Volume of a rectangular pyramid = (lwh)/3

= (28×21×26)/3

= 15288/3

= 5096 cubic millimeters

Total volume = 2352+5096

= 7448  cubic millimeters

Hence, Sophie has made mistake in copying height of pyramid.

Answer: 60 cm

Step-by-step explanation:

The actual length of the boat is 10.8 meters.

The scale model length is 1/18 of the actual boat.

Length of scale model will therefore be:

= 10.8 * 1/18

= 0.6 meters

A meter is 100 centimeters.

= 0.6 * 100

= 60 cm

When x = 4, the value of y that is missing is 16.

When x equals 6, the value of y is 24.

The graph shows a linear connection.

Given is a table of values of x and y,

x = 1, 2, 3, 4, 5

y = 4, 8, 12, ?, 20

We need to find the missing value of y corresponding to x = 4, the nature of the graph and the value of y when x = 6.

To find the missing value of y corresponding to x = 4, we can observe the pattern in the given values.

From the given values, we can see that the relationship between x and y is a linear one, where the value of y increases by 4 for each unit increase in x.

To find the missing value of y when x = 4, we can use this linear relationship.

Since y increases by 4 for each unit increase in x, we can calculate:

y = 4 + (4 × (x - 1))

Substituting x = 4 into the equation:

y = 4 + (4 × (4 - 1))

y = 4 + (4 × 3)

y = 4 + 12

y = 16

So, the missing value of y corresponding to x = 4 is 16.

Now, to find the value of y when x = 6, we can use the same linear relationship:

y = 4 + (4 × (x - 1))

Substituting x = 6 into the equation:

y = 4 + (4 × (6 - 1))

y = 4 + (4 × 5)

y = 4 + 20

y = 24

Therefore, when x = 6, the value of y is 24.

In summary:

The missing value of y when x = 4 is 16.

The value of y when x = 6 is 24.

The nature of the graph is a linear relationship.

Answer: 55 degrees

Step-by-step explanation:

so we only need to focus on the triangle with m<1 we know that it is a right triangle so there's already 90 degrees.

if we do 180 - 145 that gives us another angle measurement which is 35

now to find angle 1 we need to add 90 + 35 = 125

since there's 180 degrees in a triangle we do 180 - 125 and that gives us 55 which is the missing angle
