Answer:

  (a)  (2x +36)° +(3x +14)° = 90°

  (b)  ∠C = 38°; ∠D = 52°; ∠E = 90°

Step-by-step explanation:

(a) Two acute angles are marked in a right triangle. We know the sum of angles in a triangle is 180°, so if one of those angles is 90°, the sum of the other two angles must be 90°. We can use that fact to write and equation for x.

  (2x +36)° +(3x +14)° = 90°

__

(b) We can collect terms, subtract 50 and ...

  5x +50 = 90 . . . . . . . collect terms, divide by °

  5x = 40 . . . . . . . . . . subtract 50

  x = 8 . . . . . . . . . .. divide by 5

∠C = (3x +14)° = (3·8 +14)° = 38°

∠D = (2x +36)° = (2·8 +36)° = 52°

∠E = 90°

_____

Angle E is marked as a right angle by the little square in that corner. The measure of a right angle is 90°, by definition.

Answer:

Daniel spent $ 19.

Step-by-step explanation:

Given that, while shopping for clothes, Tracy spent $28 less than 2 times what Daniel spent, and Tracy spent $ 10, to determine how much Daniel spent the following equation must be performed:

Daniel: X

Tracy: 2X - 28 = 10

2X - 28 = 10

2X = 10 + 28

X = 38/2

X = 19

2x19 - 28 = X

38 - 28 = X

10 = X

So, Daniel spent $ 19.

Question:

Shopping While shopping for clothes, Tracy spent $28 less than 2 times what Daniel spent. Tracy

Answer:

1 [tex]\frac{1}{2}[/tex]

Step-by-step explanation:

There are a total of 2 friends, if they have 3 cereal bars and want to split it equally then we simply need to divide the number of cereal bars by the number of friends which would give us the number of cereal bars that each individual will get, which will be represented by x

x = 3 / 2

x = 1 [tex]\frac{1}{2}[/tex]

Finally, we can see that each friend will get a total of 1 and a half of a cereal bar.

Answer:

  $2.50

Step-by-step explanation:

The question asks for the total cost of a notebook and pen together. We don't need to find their individual costs in order to answer the question.

Sometimes we get bored solving systems of equations in the usual ways. For this question, let's try this.

The first equation has one more notebook than pens. The second equation has 4 more notebooks than pens. If we subtract 4 times the first equation from the second, we should have equal numbers of notebooks and pens.

  (8n +4p) -4(3n +2p) = (16.00) -4(6.50)

  -4n -4p = -10.00 . . . . . . . . . . . simplify

  n + p = -10.00/-4 = 2.50 . . . . divide by the coefficient of (n+p)

The total cost for one notebook and one pen is $2.50.

__

Additional comment

The first equation has 1 more notebook than 2 (n+p) combinations, telling us that a notebook costs $6.50 -2(2.50) = $1.50. Then the pen is $2.50 -1.50 = $1.00.

One could solve for the costs of a notebook (n) and a pen (p) individually, then add them together to answer the question. We judge that to be more work.

Answer:

110 = 12

110 + 110 + 110 + 110 = 440

so 110 × 4 = 440

4 × 12 = 48 days

Answer:

D. 2

Step-by-step explanation:

The only possible outcomes that Janessa could possibly calculate would be 5 and 6. This is because a single die has 6 possible outcomes. If Janessa's friends rolled a 3 and a 4, and Janessa needs to roll something higher, then the only higher possible outcomes would be a 5 or a 6. Meaning that Janessa can only use a total of 2 desired outcomes for her to actually win the game.

Answer:

210 degrees

Step-by-step explanation:

This question involves the unit circle. The unit circle is generally something you need to memorize, but if you can remember one quadrant you can just change the signs to apply it to other quadrants. In this case, when sinθ = -1/2, θ is 7π/6, which is equal to 210° (remember that π is equal to 180°)

Answer:

68

Step-by-step explanation:

Answer:

x = 68°

Step-by-step explanation:

measure of angle adjacent to 128° equals 52°

60 + 52 + x = 180

x = 180 - 112

x = 68

Answer:

  2580 g

Step-by-step explanation:

The conversions are ...

  1 oz = 1/16 lb

  1 lb = 453.59237 g (exactly)

So, your roast is ...

  (5 11/16 lb)(453.59237 g/lb) = (91·453.59237/16) g ≈ 2579.8066... g

The weight is about 2580 grams.
