Answer:

0.997= 997/1000

Step-by-step explanation:

It's in the thousandths place so the denominator is 1000. Then the decimal is 997, so that's the numerator

It's on the image the question

Answer:

Ok, so I hope I understood the task. Here goes nothing

Step-by-step explanation:

So, first we calculate the area of the big rectangle,

(√63+√28)*√45 = 15√35

Then we calculate the area of the small rectangle

√7*√5 = √35

Then we do this to get the area left

15√35 - √35 = 14√35

Then we take

$14 \sqrt{35 } \div 15 \sqrt{35} = \frac{14}{15}$

That should explain it

Find the probability.

kvv77 [185]

Answer:

7/36

Step-by-step explanation:

1 die has 6 faces

When two dice are rolled, the total number of outcomes

= 6 × 6 = 36

The Probability of having(5) =

(1 & 4), (2 & 3) , ( 3 & 2), (4 & 1)

= 4

The probability of having (10) =

(5 & 5), (4 & 6) , ( 6 & 4)

= 3

The probability that the score on the dice is either 5 or 10.

P(5) + P(10)

= 4/36 + 3/36

= 7/36

Tara received 28 out of 35 points on her last math test. What percentage score did the teacher record in her grade book for Tara

ZanzabumX [31]

Answer:

80%

Step-by-step explanation:

28/35 = 0.8

Divide. Convert a decimal to a percent by multiplying times 100.

0.8 × 100 = 80

Tara earned an 80%

You could use a calculator as described above or using mental math or pencil and paper:

28/35 = 4/5

Simplify.

4/5 = 8/10 = 80/100

Percent means per hundred, change 28/35 to hundredths as above.

Tara (still) gets an 80%.

A ball is thrown vertically upward. After t seconds, its height h (in feet) is given by the function h(t)=72t-16t^2. What is the

irakobra [83]

Answer:

The maximum height that the ball will reach is 81 ft

Step-by-step explanation:

Note that the tray of the ball is given by the equation of a parabola of negative main coefficient. Then, the maximum value for a parabola is at its vertex.

For an equation of the form

$at ^ 2 + bt + c$

the t coordinate of the vertice is:

$t =-\frac{b}{2a}$

In this case the equation is:

$h(t)=72t-16t^2$

$a=-16\\b=72\\c=0$

Therefore

$t =-\frac{72}{2(-16)}$

$t=2.25\ s$

Finally the maximum height that the ball will reach is

$h(2.25)=72(2.25)-16(2.25)^2$

$h=81\ ft$
