Rewrite 0.85 as a fraction in lowest terms.

Answers

Answer:

49/2, 17/20

Step-by-step explanation:

24.5=245/10=245÷5/10÷5=49/2

0.85=85/100=85÷5/100÷5=17/20

Answer:

Mixed numbers

a)  24  1/2  

b) 85/100 = 17/20

Step-by-step explanation:

a) as they asked mixed number we only have to create a fraction for the decimal 0.5 = 1/2 and rewrite 24 1/2 = 24.5

If the question asked for lowest terms 24/5 then 24.5% = 245/1000 = 49/200

b) rewrite 0.85 as a fraction in lowest terms

0.85 = 85% = 85/100 = 17/20

Part 1: Weather Analysis Plot and label the temperatures on a number line. You can create the number line by using a drawing program, by drawing it by hand and sending in a picture, or by describing in detail how the completed number line should look.

Answers

A thermometer can help us determine how cold or hot a substance is. Temperature is in most of the world measured and reported in degrees Celsius (°C). In the U.S. it is common to report temperature in degrees Fahrenheit (°F). In the Celsius and Fahrenheit scales the temperatures where ice melts (water freezes) and water boils are used as reference points.

Help pls, can you solve for x?

Answers

Answer:

X=1.5, but I may be incorrect, hope this helps!

Step-by-step explanation:

FACTS I KNOW:

X has to be less than 2 but greater than 1

Angle B and D are 90 degrees

The complete bottom side is equal to 10

All triangle angles add up to 180 degrees

All angles in rectangles and squares are 90 degrees

All rectangles have 2 sets of 2 of the same sides.

If you take a piece of the top right you could make a rectangle

It would take about .5 of the 2

Therefore X=1.5 approximately, but I may be wrong.


X=1.5 this is not correct dont mind me pls

Answers

This is the slope-intercept form, with -4 the y-intercept and m the slope
This is slope intercept form. M represents your slope, also known as rate of change, y2-y1 / x2- x1, and triangle (delta) y / triangle (delta) x.

B is your y-int. It's the initial amount you start off with.

X=60°

It’s 120 because one of the right angles is 150, and then you mirror it to the other side so 150 - 30 = 120

Step-by-step explanation:

We need to use the formula :-

2 (l + b) × h ---> For Lateral surface area

2(30+30) h = 7200

2×60×h = 7200

120 × h = 7200

h = 7200/120

h = 60 cm

Now, volume = l×b×h

= 30×30×60

= 54000 cm³ is the required answer.

Hope it helps! :D

Answer:

54000cm³

Step-by-step explanation:

7200=4*30x，so x=60

In other words, the length of the vertical side is equal to 60cm

The volume inside the kite=60*30*30=54000cm³
