HOPE IT HELPS U MARK ME AS BRAINLIEST PLEASEBrandon has a total of 187 postage stamps in his collection.
• he has 48 stamps that are each 14 millimeters wide.
• he has 139 stamps that are each 12 millimeters wide.
what is the total width of the stamps in Brandon's collection?
please help!
Answer:
233.4 Centimeters
Step-by-step explanation:
48 x 10 = 480
48 x 4 = 192
480 + 192 = 672
139 x 10 = 1390
139 x 2 = 272
1390 + 272 = 1662
1662 + 672 = 2334
2334mm = 233.4cm

Step-by-step explanation:
0.1 = 1/10
2 ⅒
Answer:
2 1/10
Step-by-step explanation:
To convert the decimal 2.1 to a fraction, just follow these steps:
Step 1: Write down the number as a fraction of one:
2.1 = 2.1
--------
1
Step 2: Multiply both top and bottom by 10 for every number after the decimal point:
As we have 1 numbers after the decimal point, we multiply both numerator and denominator by 10. So,
= (2.1 × 10)
(1 × 10) = 21
------
10
Now you have to simplify, 2 1/10.

In 60 seconds , Darrell walks 90
90
meters. Describe the unit rate at he wall
Answer:
1.5 sec by meters
Step-by-step explanation:
90 meters/60 sec=1.5
Darrel walks at a unit rate of 1.5 m/sec.
What is speed?Speed is defined as the rate of change of position in unit time.
Mathematically,
Speed = Distance/Time
Now it is given that,
Distance in walk by Darrell = 90 meters
Time taken by Darell to walk 90 meters = 60 seconds
Therefore Speed i.e unit rate of walk is given as,
Unit rate of walk = Distance in walk by Darrell / Time taken by Darell to walk 90 meters
⇒ Unit rate of walk = 90/60 m/sec
⇒ Unit rate of walk = 3/2 m/sec
⇒ Unit rate of walk = 1.5 m/sec
Thus, Darrel walk at a unit rate of 1.5 m/sec.

A triangle has sides with lengths of 17 inches, 20 inches, and 28 inches. Is it a right triangle?
Answer:
no
Step-by-step explanation:
Pythagoras theorem
a2 + b2 = c2
the hypotenuse side is always the longest so its 28
:
[tex]17 { }^{2} + 20 ^{2} = 28 ^{2} [/tex]
289+ 400 =784
689 = 784
so the triangle is not a right angled triangle

We see an increase of 10y per x, which is where we get "10x"
This means that at x = 1, y = 15, which is where we get "+ 15"
21.)
Plug in 6 for x
y = 10(6) + 15
y = 60 + 15
y = 75

Write the equation of the line through
(0, 4) and (2, 0) in slope-intercept form.
Answer: y = -2x + 4
Step-by-step explanation: slope intercept form is "y=mx+b" where m is the slope and b is they y intercept. the y intercept is when x=0 and it's given to us in the question. the y intercept is (0,4). so y=4. we can plug that into the equation to now have y=mx + 4.
now we need to find the slope. we can do this by plugging the two points into the formula [tex]\frac{y2-y1}{x2-x1}[/tex]. so we'd have [tex]\frac{0-4}{2-0}[/tex] to get -4/2 which is -2. -2 is the slope.
so the final answer is y = -2x + 4
