Multiply simplified answer and give as a mixed number
6 3/5 multiply by 2 1/4

Answers

Answer:

[tex]14\frac{17}{20}[/tex]

Step-by-step explanation:

[tex]6\frac{3}{5} (2\frac{1}{4})\\\\\frac{33}{5} (\frac{9}{4} )\\\\\frac{297}{20} = 14\frac{17}{20}[/tex]

Answer:

14  17/20

Step-by-step explanation:

Convert the mixed numbers to improper fractions first.

So 6 3/5 =33/5  and 2 1/4 =9/4

Then multiply 33/5 x 9/4

33 x 9=297  

5 x 4 =20

Then convert 297/20 back to a mixed number by dividing

14 x20 =280

you have 17/20 left

Is 2(x-y) and 2x-2y equivalent

Answers

Answer:

Yes

Step-by-step explanation:

Start with the 2(x-y) and distribute the 2 to each term

2(x)-2(y)

This would equal

2x-2y

Which matches the second equation making the answer yes.

The pairs of expressions that are equivalent are:

- [tex]\( 2(x-y) \)[/tex] and [tex]\( 2x-2y \)[/tex]

- [tex]\( 4(x+y) \)[/tex] and [tex]\( 4y+4x \)[/tex]

- [tex]\( 21q-7p \)[/tex] and [tex]\( (3q-p)(7) \)[/tex]

Let's simplify each expression to see if they are equivalent.

Step 1

1. [tex]\( 2(x-y) \)[/tex] and [tex]\( 2x-2y \)[/tex]:

  Simplifying [tex]\( 2(x-y) \)[/tex]:

 [tex]\[ 2(x-y) = 2x - 2y \][/tex]

  Yes, they are equivalent.

Step 2

2. [tex]\( 4(x+y) \)[/tex] and [tex]\( 4y+4x \)[/tex]:

  Simplifying [tex]\( 4(x+y) \):[/tex]

 [tex]\[ 4(x+y) = 4x + 4y \][/tex]

  Yes, they are equivalent.

Step 3

3. [tex]\( 21q-7p \)[/tex] and [tex]\( (3q-p)(7) \)[/tex]:

  Simplifying  [tex]\( (3q-p)(7) \)[/tex]:

[tex]\[ (3q-p)(7) = 21q - 7p \][/tex]

  Yes, they are equivalent.

Step 4

4. [tex]\( 4(2a-3v) \)[/tex] and [tex]\( 8a+6v \)[/tex]:

  Simplifying [tex]\( 4(2a-3v) \)[/tex]:

 [tex]\[ 4(2a-3v) = 8a - 12v \][/tex]

  No, they are not equivalent.

Step 5

5. [tex]\( 8(3x+c)-1 \)[/tex] and [tex]\( 8c+24x-1 \)[/tex]:

  Simplifying [tex]\( 8(3x+c)-1 \)[/tex]:

  [tex]\[ 8(3x+c)-1 = 24x + 8c - 1 \][/tex]

  No, they are not equivalent.

Step 6

6. [tex]\( 4p+3c \)[/tex] and [tex]\( (c+2p)(2) \)[/tex]:

  Simplifying [tex]\( (c+2p)(2) \)[/tex]:

[tex]\[ (c+2p)(2) = 2c + 4p \][/tex]

  No, they are not equivalent.

[tex]\( (3q-p)(7) \)[/tex]

Complete correct question:

Determine whether each pair of expressions is equivalent.

2(x-y) and 2x-2y

4(x+y) and 4y+4x

What is the Pythagoras theorem?

Pythagorean theorem, the well-known geometric theorem that the sum of the squares on the legs of a right triangle is equal to the square on the hypotenuse (the side opposite the right angle)—or, in familiar algebraic notation, a² + b² = c².

Given here, Sin C = x/1 and therefore Hypotenuse = 1 and perpendicular =x

thus Base=1-x² by phytogaraen theorem.

Thus Sin A=1-x² /1

Hence, Sin A= 1-x² is the correct answer.

Factor this expression: 40-100m

Answers

Answer:

10(4-10m)

Step-by-step explanation:

You have to find something that can go out of both of the numbers.

10 is the highest that i could find.

So you basically have to put the number on the outside of the racks.

Then divide it.

40-100m

÷10 ÷10

whats left is 4-10m

The variable can't be divided with it since it doesn't have another variable to go with.

Final answer:

The expression '40 - 100m' can be factored by finding a common number, which, for 40 and 100, is 20. On factorizing the expression we get: '-20(2 - 5m)'.

Explanation:

The expression '40 - 100m' can be factored by finding a common number that both 40 and 100 can be divided by. This number is 20, but since we also have -100m, we'll use -20. Therefore, the factored form of '40 - 100m' is '-20(2 - 5m)'. Here is the step-by-step process.

Identify numbers that both 40 and 100 can be divided by evenly; in this case, 20.

Factor out the common number from the original expression, which gives '-20(2 - 5m)'.

Find the area(now I need to make this 20 words longfheieh)

Answers

Given:

Image of the figure

To find:

The area of the figure.

Solution:

The image is splitted into two shapes.

One is rectangle and the other is trapezium.

Reference image for answer is attached below.

Rectangle:

Length = 10 cm

Width = 2.8 cm

Area = length × width

        = 10 × 2.8

Area = 28 cm²

Trapezium:

Top base = 6 cm

Bottom base = 10 cm

Height = 7.2 - 2.8 = 4.4 cm

Area = [tex]\frac{1}{2} \times(b_1+b_2)\times h[/tex]

        [tex]$=\frac{1}{2} \times(6+10)\times 4.4[/tex]

        [tex]$=\frac{1}{2} \times16\times 4.4[/tex]

Area = 35.2 cm²

Area of the figure = 28 cm² + 35.2 cm²

                              = 63.2 cm²

The area of the figure is 63.2 cm².

50 POINTS SUMMARISE THIS ARTICLEYou're mostly stuck inside, you are home from school and the coronavirus pandemic is making the future seem less certain by the day. The coronavirus is a flu-like illness that first arose in China. The virus has now infected people around the globe. Like 27 percent of Americans, you might seek comfort in a familiar place: the refrigerator.Food can be one of the easiest and most immediate ways to make ourselves feel better in stressful times. While enjoying our food is a good thing, experts say emotionally eating lots of food with little nutritional value can weaken our immune systems and worsen our moods at a time when it's especially important to stay positive and protect our bodies.If we want to be able to feel better, given the situation that we're in, we have to think about how we want to fuel our body in ways that we can stay more at ease," said Eva Selhub, a doctor with expertise in stress, resilience and mind-body medicine.Why do my eating habits matter right now?Selhub says that people may feel guilty or shameful for eating highly processed foods with a lot of sugar. Eating these foods can also cause inflammation in the body that increases fatigue, anxiety and depression. Selhub added that our bodies have various ways of connecting our stomachs to our brains, so eating nutritious foods can help control our moods. How can I tell if I'm eating because of emotion and not because of hunger?Eating as a result of stress tends to be an automatic instinct, like putting your hand into a bag of potato chips without thinking about it, said Deanna Minich, a nutritionist with the American Nutrition Association. Physical hunger lasts longer and is more receptive to a variety of foods, rather than just foods with little nutrition.How can I prevent or limit emotional eating in this uncertain time?Although food makes us feel better by releasing dopamine and serotonin in our brains, Selhub said the effect wears off quickly. To stop emotional eating, she suggested doing a gut-check before you reach for a snack: "Am I about to eat because I'm physically hungry, or because I feel stressed or sad?"If the answer is the latter, Selhub said you should consider turning to other sources of comfort: breathing exercises, movement, spirituality, social interactions, hobbies or time in nature, among others. Stick to your normal eating schedule of two or threemeals a day, even if your daily routine has changed, she said."Whether you're alone or with other people, make it a ritual of nurturing - that you're nurturing yourself, that you're fueling yourself," Selhub said.For extra help if you want to stay on track with trying to get in shape or lose weight, she suggested finding or creating an online support group.What if anxiety has the opposite effect on me and I struggle to eat enough?Although many people eat extra when they feel anxious, you may have trouble eating at all. Stress can trigger in your body an elevated physiological state as if you were facing an immediate danger, like early humans may have felt when being chased by a lion, Selhub said.To digest food properly, we need a relaxed digestive system, Minich said. Warm teas can help your body loosen up, while protein shakes and electrolyte packets provide energy.At the very least, Minich said you should drink a lot of water to stay hydrated. To return to regular eating patterns, though, she said it's important to address the underlying stress, like by physically moving or doing a simple meditation.What should I be trying to eat during this public-health crisis?Making good food choices starts when you're scanning the - hopefully still stocked - grocery-store shelves and deciding what to take home, Minich said. To the extent that you can buy fresh, colorful foods, you should, she said.Absent the option of purchasing fresh produce and meat, Minich said frozen almost always beats canned when it comes to nutrition. Frozen food is preserved in close to its original state and usually has little interaction with the plastic it's stored in, she said, whereas canned food touches its metal container and the plasticizer used to seal it. Canned food is also usually stored in a high-salt or high-sugar solution.Minich also suggested using spices to reduce stress-inflicted inflammation and eating foods with vitamin C to strengthen your immune system. Now is a good time to share recipes with friends and family, she said, and to make sure you're also paying attention to other aspects of your health, such as moving your body and getting enough sleep.Ultimately, Minich said eating well heightens our sense of well-being, increases our curiosity and makes us happier."And I think this is the time that we need more well-being and happiness," she said.
