Answer:

No.

Step-by-step explanation:

Ratio of any objects can be calculated by dividing the two objects with the common number.

Boys in the sixth grade = 35.

Girls in the sixth grade = 42.

Ratio of boys to girl = \frac{boys}{girls}

Ratio = \frac{35}{42}

Ratio = 5:6. (the numbers are divided by 7).

Thus, the ratio is 5:6 and not the 5:7.

Thus, Lonnie is not correct.

No... 35 divided by 7 is 5 and 42 divided 7 is 6 ... it should actually be 5:6

A triangular prism is shown. a cylinder is cut out of the center of the prism. the triangular base has side lengths of 14 and 10
Whitepunk [10]

The expression that represents the volume, in cubic units, of the shaded region of the composite figure is: A. One-half(14)(10)(8) – π(2.52)(8).

<h3>Expression</h3>

Given:

Base side length=14 and 10 units

Height=8 units

Diameter=5 units


Hence:

Expression= 1-( half 14)(10)(8) - π(2.52)(8)

Expression=1-(7) (10)(8) - π(2.52)(8)

Expression=1- (560)- 63.33

Expression=-559-63.33

Expression=-622.33

Therefore the expression that represents the volume, in cubic units, of the shaded region of the composite figure is: A. One-half(14)(10)(8) – π(2.52)(8).
