Answer:

Sadie took 47 minutes to finish her test.

Step-by-step explanation:

Let Laura's time be x minutes.

Then we have:

x + 3x - 16 = 68

4x = 84

x = 21 minutes.

So Sadie took 3(21) - 16 = 63-16

= 47 minutes.

Can someone help pls!!!
natita [175]
Answer: 42.14 cm^2

square:

Area of a square=s^2
A=14^2
A=196

circle (the two semi circles are the same as one circle):

Area of a circle=(pi)(r)^2

divide 14 (diameter) by 2 to find the radius

A=(3.14)(7)^2
A=(3.14)(49)
A=153.86

subtract the area of the two semi circles from the area of the square to get the answer

196-153.86=42.14

In the figure below, one side of the right triangle is a diameter of the semicircle.
olga55 [171]

Answer:

Option (A)

Step-by-step explanation:

One side of the given triangle is a diameter of the semicircle given.

Measure of the diameter = 10 units

Total area of the semicircle = \frac{1}{2}\pi (r^{2})

                                              = \frac{1}{2}\pi (5)^2

                                              = 39.27 square units

Area of the right triangle = \frac{1}{2}(\text{Base})(\text{Height})

                                         = \frac{1}{2}(6)(8)

                                         = 24 square units

Area of the shaded region = Area of the semicircle - Area of the right triangle

                                            = 39.27 - 24

                                            = 15.27 square units

                                            ≈ 15 square units

Therefore, option (A) will be the answer.

What is the quotient of 10?
olya-2409 [2.1K]

A quotient is the result of dividing one number by another. For example, the quotient of 6 and 3 equals 6/3 or 2. In your problem above it is asking you to provide the quotient of 10 and 2 meaning you divide the 2 into the ten and end up with 10/2 or 5.

So I think the answer is 10/2 or 5

Of all the species in the world, 4 out of every 5 are insects what percentage of species are insects
Fiesta28 [93]

Answer:

80%

Step-by-step explanation:

So you basically, just make it a ratio. Since a percentage is out of 100, just make the 5 into 100. To get 5 to 100, you times 20. Then you do the same thing to the 4 which you get 80.
