Answer 1

Step-by-step explanation:

a) given slope=m1=a/3

slope of parallel line=m2=5/6

parallel lines have equal slopes:

m1=m2

a/3=5/6

a=5/6×3

a=5/2

b) m1=a/3

m2=-2/9

lines are parallel:

m1=m2

a/3=-2/9

a=-2/9×3

a=-2/3

c)m1=a/3

m2=6

Slopes are perpendicular:

m1×m2=-1

a/3×6=-1

a×2=-1

a=-1/2

d)m1=a/3

m2=6/7

lines are perpendicular:

m1×m2=-1

a/3×6/7=-1

a×2/7=-1

a=-7/2

29 dekagrams equals 2900 what

Answers

Answer:

It equals 2900 decigrams

Step-by-step explanation:

29 dekagrams = 290 grams

290 grams = 2900 decigrams

Therefore, 29 dekagrams = 2900 decigrams

The equivalent weight in grams for a given weight in dekagrams is approximately 10 times the weight in dekagrams.

To find the equivalent weight in grams for a given weight in dekagrams, you can use the conversion factor that 1 dekagram (dag) is equal to 10 grams.

Given the information that 29 dekagrams equals 290 grams, you can set up a proportion:

[tex]\(\frac{29 \text{ dag}}{290 \text{ g}} = \frac{1 \text{ dag}}{x \text{ g}}\)[/tex]

Cross-multiplying:

[tex]\(29x = 290 \times 1\)[/tex]

Solving for x:

[tex]\(x = \frac{290}{29}\)\\\\\(x \approx 10\)[/tex]

Therefore, the equivalent weight in grams for a given weight in dekagrams is approximately 10 times the given weight in dekagrams.

On Monday it snowed 8 in. On Tuesday the
snow melted 3 in. On Wensday it showed
another 5 in. How much snow
was on the
ground after it snowed on Wednesday?

Answers

Answer:

10in

Step-by-step explanation:

8-3=5

5+5=10

Answer:

10 inches.

Step-by-step explanation:

Assuming that before Monday, there was no snow.

On Monday, it snowed 8 inches, which is a net positive of 8:

0 + 8 = 8in total.

On Tuesday, it melted 3 inches, which is a net negative of 3:

8 - 3 = 5in total.

On Wednsday, it snowed another 5 inches, which is a net positive of 5:

5 + 5 = 10in total.

10 inches total of snow was on the ground on Wednesday.

The length of a rectangle is 15 cm and the width is 8 cm which is the perimeter of the rectangle

Answers

Answer:

46

Step-by-step explanation:

Perimeter = 2(15 + 8)

Perimeter = 46

Answer:

46 cm

Step-by-step explanation:

To calculate the perimeter of a rectangle, you have to add the length with itself then add the width with itself. After that, you add both of the sums together to get the answer. For this particular question, this is what you have to do.

1.Add the length with itself 15+15=30

2.Add the width with itself 8+8=16

3. Add both sums 30+16=46

In conclusion, the perimeter of the rectangle is 46 centimeters.

I used pathagorus theorem .All explaination is in the pic below.

please help me with this. thanks a lot​

Answers

Answer:

Part A)

Approximately 318.1318 meters.

Part B)

Approximately 137.7551 meters.

Step-by-step explanation:

The path of a projectile is given by the equation:

[tex]\displaystyle y = \sqrt{3} x -\frac{49x^2}{9000}[/tex]

Part A)

The range of the projectile will be given by the difference between its starting point and landing point. In other words, its two zeros.

Let y = 0 and solve for x:

[tex]\displaystyle 0 = \sqrt{3}x - \frac{49x^2}{9000}[/tex]

Factor:

[tex]\displaystyle 0 = x\left(\sqrt{3} - \frac{49x}{9000}\right)[/tex]

Zero Product Property:

[tex]\displaystyle x = 0 \text{ or } \sqrt{3} - \frac{49x}{9000} = 0[/tex]

Solve for each case:

[tex]\displaystyle x = 0 \text{ or } x = \frac{9000\sqrt{3}}{49}\approx 318.1318[/tex]

Hence, the range of the projectile is approximately (318.1318 - 0) or 318.1318 meters.

Part B)

Since the equation is a quadratic, the maximum height is given by its vertex. Recall that the vertex of a quadratic is given by:

[tex]\displaystyle \text{Vertex} = \left(-\frac{b}{2a}, f\left(-\frac{b}{2a}\right)\right)[/tex]

In this case, a = -49/9000 and b = √3.

Find the x-coordinate of the vertex:

[tex]\displaystyle x = - \frac{(\sqrt{3})}{2\left(\dfrac{-49}{9000}\right)} = \frac{4500\sqrt{3}}{49}[/tex]

Then the maximum height will be:

[tex]\displaystyle \displaystyle \begin{aligned} y\left(\frac{4500\sqrt{3}}{49}\right) &=\sqrt{3} \left(\frac{4500\sqrt{3}}{49}\right) -\frac{49\left(\dfrac{4500\sqrt{3}}{49}\right)^2}{9000} \\ \\ &= \frac{13500}{49} -\frac{6750}{49}\\ \\ &=\frac{6750}{49}\\ \\ &\approx 137.7551\text{ meters}\end{aligned}[/tex]

The maximum height reached by the projectile will be 137.7551 meters.

At a hotel 3/4 of 100 rooms are occupied today yesterday 4/5 of 100 rooms were occupied on which day were more rooms occupied in by how much

Answers

Answer:

Yesterday 4/5 and by 5 more people

Step-by-step explanation:

Ok so 3/4 of 100 is just 100/4*3, which is 75. 4/5 of 100 is 100/5*4, therefore, equaling 80. So 80 > 75, and when you find by how much more you do 80-75, which is 5. I hope this helps and if you have any questions you can comment them on this answer

Answer:

The answer is 4/5

Step-by-step explanation:

well 3/4 of 100 is 75. 4/5 of 100 is 80.

one fourth is equal to 25. We know that because we divide 100/4 and since there's 3 out of 4 (25x3=75)

one fifth is equal to 20. (100/5 = 20) 4 times 20 equals 80

We know that 3 + 5 = 8 so 3t + 5t must be 8t.

We still have the 4y left over so we get 8t + 4y. We cannot simplify this expression anymore

So, the answer is [tex]8t + 4y[/tex] as our answer.

Option B is correct

The number of real number solutions for the given equation is, 1.

Step-by-step explanation:

Given the equation:  

Since, this is a quadratic equation of the form of  

where a =1 , b = -10 and c =25.

The discriminant of a quadratic equation is,  

then;

Discriminant =  = (100-100) = 0
