Answer:

Step-by-step explanation:

You see the hunderth digit has a 8, so you round up. 0.9+0.1=1 so you add 1 to 3, so 3.987 rounded is 4

To round it to the nearest tenth you have to look at the number beside the tenths place and if that number is 5 or above u round the tenths place up. So since that number is an 8 u round the 9 to 0 which then changes the 3 to 4 so your final answer should be 4.0

Find the distance between the points (7, – 9) and ( – 2, – 4).

Masja [62]

Answer:

7.07106781187

Step-by-step explanation:

Let us use the distance formula:

$d = \sqrt{(x_2 - x_1)^2 + (y_2-y_1)^2}$

x2=2

x1=7

y2=4

y1=9

$d = \sqrt{(2 - 7)^{2} + (4-9)^2}$

$d = \sqrt{(-5)^2 + (-5)^2}$

$d = \sqrt{25 + 25}$

$d = \sqrt{50}$

d=7.07106781187 (round to whatever digit neccesary)

Hope this helps!!

BRAINLY ❗️❗️❗️ 1️⃣2️⃣. The triangle shown has an area of 8 15/16 square feet, and 5 1/2 ft base. What is the height, in inches?

svetlana [45]

The formula of area of triangle is

$Area,A = \frac{1}{2}bh$

where b is the base and h is the height .

First we need to convert the mixed fraction to improper fraction, and on doing so we will get

$Area,A= 8 \frac{15}{16} = \frac{143}{16} \\ Base, b = 5 \frac{1}{2} = \frac{11}{2}$

Substituting the values of A and b, we will get

$143/16=(1/2)(11/2)h \\ 143/16=(11/4)h \\ 13/4=h=> h = 3\frac{1}{4}feet$

Q # 4 please help to solve

galina1969 [7]

The second choice - 3.1%

All you have to do is multiply the probability by itself five times to get the total probability for the next five days.

1/2*1/2*1/2*1/2*1/2
= 1/2!
= 1/32
= 0.0313
= 3.13%

3.13 rounded off to the nearest tenth is 3.1%
There is 3.1% probability that Shania will arrive at school on time for the next five days.
