Answer: 74.9 millimeters
Step-by-step explanation:
From the question, a photo of a beetle in a science book was.increased to 535% as large as its actual size and the beetle.has a actual size of 14 millimeters,
The size of the beetle on the photo will be 535% of 14 millimeters. This will be:
= 535% of 14
= 535/100 × 14
= 5.35 × 14
= 74.9 millimeters

Answer:
1
Step-by-step explanation:
Follow the signs rule:
IF:
There is a + sign, and the number directly next is +, add
There is a + sign, and the number directly next is -, subtract
There is a - sign, and the number directly next is +, subtract
There is a - sign, and the number directly next is -, add
In this case, there is a plus sign, and a negative sign, therefore, subtract:
5 + (-4) = 5 - 4 = 1
1 is your answer.

Answer: C. 17.5 feet
Step-by-step explanation:
The attached photo shows the triangle ABC formed by the ladder and the wall. It is a right angle triangle because one of its angles is 90 degrees. The ladder is the hypotenuse of the triangle. To determine the height of the wall, we would find BC by applying Pythagoras theorem
Hypotenuse^2 = opposite ^2 + adjacent^2
18^2 + 4.5^2 + BC^2
BC^2 = 324 - 20.25 = 303.75
BC = √303.75 = 17.5 feet.
Step-by-step explanation:
AC= 8x-14
AC+14=8x
x=(AC+14)÷8
EC=2x+11
EC-11=2x
x=(EC-11)÷2
