Answer:

17.58 KL

Step-by-step explanation:

.

Answer:

17.584 kl.

Step-by-step explanation:

1 kl = 1,000,000 cm^3.

So the answer is  17.584 kl.

The axis of symmetry is the fold line that splits the parabola down the middle.

Now, since a parabola is symmetrical, every point, except the vertex, will have a mirror image of another point if we folded the parabola over the axis of symmetry.

So if we know the axis of symmetry is x = 3 and one of our points

has the coordinates (5, 0), the other point will have the coordinates (3, 0).

The axis of symmetry is always halfway between the x-intercepts.

Step-by-step explanation:

Emi evaluated (46 - 78)² as -(32)². The variance of the given data is 274. Therefore, option C is the correct answer.

Given that, the population data set is 87, 46, 90, 78, and 89.

Here, mean = [tex]\bar x[/tex] =78 and n=5

We know that, mean [tex]\bar x=\frac{\sum x_i}{n}[/tex] and variance = [tex]\sigma^2=\frac{\sum (x_i-\bar x)^2}{n}[/tex].

Here, σ² = [(87-78)²+(46-78)²+(90-78)²+(78-78)²+(89-78)²]/5

= (9²+(-32)²+12²+0²+11²)/5

= (81+1024+144+121)/5

= 1370/5

= 274

So, the variance is 274.

Therefore, option C is the correct answer.

Answer:

P =3Q +21

Step-by-step explanation:

Given: Rahim was asked to make p the subject of this formula

Q = p/3 - 7

He started his answer as follows

3Q = p - 21 hence p =

To Find, Complete Rahim's final answer.

Solution:

Q = p/3 - 7

Multiply both sides by 3

3Q = 3(p/3 - 7)

3Q = 3 × p/3 - 3 × 7

3Q = p - 21

Adding 21 both sides

3Q + 21 = p -21 +21

3Q + 21 = p

interchange sides

p = 3Q + 21

hence p =3Q +21

Answer:

I just learned this about a few weeks ago I hope this helps.

Step-by-step explanation:

Since it's cosine you're only looking at Adjacent and the hypotenuse which the adj is 20 and the hyp is 25 so since cosine is adj/hyp you do 20/25 then simplify it to 20/25 divide both by 5 so it's simplified to 4/5.

Then you do Cos-1(4/5)=36.869 which is rounded to the tenth 36.9 but rounded to the hundredth 36.87.

Answer:

8.5

Step-by-step explanation:

First we need to get BC using the pythagoras theorem

BC² = AC² + AB²

BC² = 8² + 15²

BC² = 64+225

BC² = 289

BC = √289

BC = 17

DB = 1/2BC

DB = 1/2 * 17

DB = 8.5

Hence the length of DB is 8.5

Answer:

49.5 ounces the flower

3 pounds, 1.5 ounces

Step-by-step explanation:

Given that :

24 cupcakes 9 ounces of flower

Number of ounces of flower required for 132 cupcakes will be x

Using cross multiplication method :

24 cupcakes = 9 ounces

132 cupcakes = x ounces

Cross multiply :

24 * x = 132 * 9

24x = 1188

divide both sides by 24 to isolate x

x = 49.5

Hence, 49.5 ounces the flower is required for 132 cupcakes

To express in pounds :

1 pound = 16 ounces

49.5 ounces = 3 pounds 1.5 ounces

Answer: 150mm

Step-by-step explanation:

We should note that 10 millimeter = 1 centimeter. Therefore, 70cm to mm will be:

= 70 × 10 = 700mm

Frog one jumped 70cm = 700mm

Frog two jumped 850mm

The difference between the distance will be:.

= 850mm - 700mm

= 150mm

Step-by-step explanation:

y= 1 + 3x

the first one is 2. we replace x with 2. now we have 1+3*2. We would have to multiply 3 and 2 which is 6. Now we have 1+6. which equals 7. Next one is 4 times 3 equals 12. 12 + 1 =13. Next one 6 times 3 equals 18. 18 + 1 = 19. The same thing for the next one

Answer:

100

Step-by-step explanation:

Remark

If two opposite arcs are given by being opposite vertically opposite angles, then the value of both the vertically opposite angles are equal to

Vertically opposite angle = 1/2 (arc1 + arc2)

Givens

Arc1 = 60

Arc2 = 100

Solution

The red dot angle = 1/2 (60 + 100)

The red dot angle = 1/2(160)

The red dot angle = 80

Because the red dot angle and <3 are on the same line with the same common point, they are supplementary.

<3 and red dot = 180

<3 + 80 = 180                          Subtract 80 from both sides

<3 = 180 - 80

<3 = 100

Answer:

x - y = 5

Explanation:

As you can see in the first problem the ration is x to y = 8 to 3. This means for every 8 x values, there are 3 y values. Therefore, x - y should be the same as 8 - 3, which is 5.
