0.985 rounded to the nearest tenth

1 answer:

8 0

They always try to trick you with this. Remember anything 5 or above would round up, anything 4 and under would round down. So look for the tenth place. that's the 9. The number to the right is 8 which is greater than 5. That means round up. You can't round it to 0.1 because that takes it back down. So you just move it over. The answer is 1.0.

A bug completes one lap along the edge of a circular planter of radius 11.7 cm in 13.91 s. How fast was it traveling? 1. 10.8518

IrinaK [193]

Answer:

8.5.28492 cm/s

Step-by-step explanation:

We are given that

Radius of circular planter=11.7 cm

Time taken by bug =13.91 s

We have to find the speed of bug.

We know that

Speed = $\frac{distance}{time}$

Distance traveled by bug = $2\pi r$

Distance traveled by bug = $2\times 3.14\times 11.7$

Because $\pi=3.14$

Speed of bug= $\frac{2\times 3.14\times 11.7}{13.91}=5.28224 cm/s$

Hence, speed of bug=5.2822 4 cm/s

Answer:8.5.28492 cm/s

To the nearest square inch, how much fabric will she use to make all three triangles? 139 square inches 172 square inches 417 sq

horrorfan [7]

Applying the trigonometric area formula, the amount of fabric she will need to make all the three triangles is: C. 417 square inches.

<h3>What is the Trigonometric Area Formula?</h3>

The trigonometric area formula is expressed as: Area = 1/2 × ab × sin(C).

Find the area of one of the triangles:

a = 17 in.

b = 17 in.

C = 74°

Area = 1/2 × (17)(17) × sin(74) ≈ 139 sq. in.

Area of the three triangles = 3(139) = 417 square inches.

Seventh grade students were asked whether they participated in an after school activity. Complete the table below.

Natalka [10]

Answer:

Relative frequency of male nonparticipation is O.42

Step-by-step explanation:

Figure 1 is your partially filled frequency table.

1. Complete the table

(a) Total No

Total Yes + Total No = Total

102 + Total No = 187

Total No = 187 - 102

= 85

(b) Female No

Male No + Female No = Total No

40 + Female No = 85

Female No = 85 - 40

= 45

(c) Female Yes

Female Yes + Female No = Female Total

Female Yes + 45 = 95

Female Yes = 95 - 45

= 50

(d) Male Yes

Male Yes + Female Yes = Total Yes

Male Yes + 50 = 102

Male Yes = 102 - 50

= 52

(e) Male Total

Male Yes + Male No = Male Total

52 + 40 = Male Total

Male Total = 92

Figure 2 shows the completed table.

2. Frequency of Male No

There are 92 males, of whom 40 do not participate in an after-school activity.

The relative frequency of male nonparticipation is

40/92 = 0.43
