.

Answers

Answer:

For the fraction model, fill the whole left bar, and only 1 in the right bar.

The addition equation is:

⅙ + ⅙ + ⅙ + ⅙ + ⅙ + ⅙ + ⅙ = 7/6

Explanation:

Since the bar is divided into sixths (1/6 each), just count by 1/6 each time you fill each one and use the equation to represent the process.

The triangle shown on the coordinate grid is translated 6 units to the right and 3 units down.
Which would be the measure of an angle of the resulting triangle?
(ignore the answer i choose lol) but pls help me

Answers

Answer:

75°

Step-by-step explanation:

Even if a triangle is translated, the original shape stays the same.

So, to get the answer, first add the first two angles of the triangle:

60 + 45 = 105

Then, subtract from 180, because 180 is equaled to all the angles added up on any triangle:

180 - 105 = 75.

So, you get 75°.

The felt costs 9¢ per square inch. She will only pay for the felt used to cover the box, even if there is waste or extra. How much money did Hazel spend on the felt? (1 point)

a
$18.18

b
$27.72

c
$36.36

d
$45.54

Answers

Answer:

C. $36.36

Step-by-step explanation:

You need to find the surface area of the box. Then, calculate how much it will cost.

SA = 2(wl + hl + hw)

SA = 2([11*8] + [6*8] + [6*11])

SA = 2(88 + 48 + 66)

SA = 2(202)

SA = 404 inches

9 cents per inch

0.09*404 = 36.36

Answer:

a) 3/2 or 1 1/2

b) 5/3 or 1 2/3

Step-by-step explanation:

1/2 + 1/2 + 1/2 =

3 x 1/2 =

3/2 or 1 1/2

1/3 + 1/3 + 1/3 + 1/3 + 1/3 =

5 x 1/3 =

5/3 or 1 2/3

Answer: (a) 1 1/2 and (b) 1 2/3

Step-by-step explanation: (a) 1/2 + 1/2 + 1/2 = 1/2 x 3

= 3/2
Now convert this into mixed fractions (basically divide the smaller number of the improper fraction by the the bigger one).

Therefore, 3/2 = 1 1/2 ( 1 1/2 is 1 whole and 1/2)

(b) 1/3 + 1/3 + 1/3 + 1/3 + 1/3 + 1/3 = 1/3 x 5
= 5/3

mixed number = 1 2/3 ( 1 2/3 is 1 whole and 2/3)

Answer:26

Step-by-step explanation:Since angles 1 and 2 are supplementary, it follows that there sum is 180°.

On this note;

Sum of 1 and 2 is;

180 = 124 + (2x + 4)°

(2x + 4)° = 180 -124

From midnight to 2:00 am, the temperature rose
1.55
1.55°C each hour. If the temperature at midnight was
−
7
−7°C, what was the temperature at 2:00 am?

Answers

Answer:

-3.90

Step-by-step explanation:

1) 1.55+1.55 =3.10

2) -7+3.10= (-3.90)

The answer is -3.9 degrees Celsius because 1.55+1.55=3.10 (We do this because 1h= +1.55 so 2h = +3.10) and then we do -7+3.10= 3.90 degrees Celsius (we do this because we do the initial temperature plus the temperature risen in 2 hours)

c.) y = (3x)2 - 36

when x = 0.66

Answers

Answer:

a) y = 55

b) y = 45

c) y = -18

d) y = 5.45

Step-by-step explanation:

y = 15x - 50 when x = 7

y = 15(7) - 50

y = 105 - 50

y = 55

y = 1/2x + 20 when x = 50

y = 1/2(50) + 20

y = 25 + 20

y = 45

y = (3x)2 - 36 when x = 3

y = (3(3))(2) - 36

y = 9(2) - 36

y = 18 - 36

y = -18

y = 2.5x + 3.8 when x = 0.66

y = 2.5(0.66) + 3.8

y = 1.65 + 3.8

y = 5.45
